© 2003 Sony Corporation Introduction 2 DVD Handycam TECHNOLOGY HANDBOOK CAMCORDERS: AN INTRODUCTION CAMCORDERS: AN INTRODUCTION Sony led the way in video camcorders. The first consumer cassette camcorder was developed by Sony. And in 1985, Sony's compact, lightweight 8mm Handycam® camcorders expanded the world of home video by making memories easy to shoot, play, and share anytime, anywhere. Sony also led the way in digital technology. Sony CD and MD recording raised the standard of excellence in music reproduction. And Sony DV Handycam models adopted digital video for high-quality recording and multi-generation editing. Now, Sony takes the next step in digital video: DVD Handycam® camcorders. They use DVD discs as their digital recording medium -- so movies can be shot on disc, stored on disc, edited in the camcorder, even uploaded to a PC for creative editing and easy sharing. DVD offers significant advantages over cassette tape. Discs allow instant access and rapid scene search without fast-forward or rewind. They record video, audio, even still images. They're more compact and durable as a storage and playback medium. Best of all, DVD recordings can be played back on PCs, DVD players, even PlayStation® 2 video game consoles -- for instant compatibility with over 100 million playback devices around the globe. Sony DVD Handycam camcorders are new and exciting. This handbook explains basic DVD technology, highlights DVD Handycam camcorder features, answers common questions, and helps you understand and appreciate the exciting possibilities of this next step in camcorder evolution.

Today, DVD is accepted worldwide, in use for a broad range of applications -- and its next major impact will be felt in the home video recording market. The development of DVD started 12 years ago. Inspired by the success of the CD (Digital Audio Compact Disc) format for music and data recording, manufacturers began working toward the goal of a new disc format that would hold two or more hours of high-quality video recording. In 1994, two standards were proposed: “MMCD,” from Sony and Philips, and “SD,” from Toshiba and Pioneer. At the end of 1995, an agreement was reached on a common standard. At this point the DVD Consortium was formed and DVD was ready for marketing. Its first applications were for prerecorded movies and computer software (DVD-ROM). Recording standards soon followed; the DVD-R Book and DVD-RAM Book standards were defined in 1997. In 1999, the DVD-RW Book defined a 4.7 GB rewritable disc format using a short-wavelength red semiconductor laser. Currently, standardization efforts are underway to define a next-generation optical disc system using blue laser technology. 1996 1997 DVD-Video DVD-R/DVD-RAM/DVD+RW 1998 1999 DVD-RW 2000 2001 2002 DVD+R Next-generation optical disc DVD Advantages 1 2 DVD is more compact DVD is more durable Because DVD discs are more compact than videocassettes, they take up less space inside the camcorder and are easier to carry, shelve and archive. Videocassette recording requires contact between videotape and recording head. In the DVD system, the optical laser pickup does not touch the disc itself, so there is far less wear during recording and playback. 3 4 DVD provides random access Videotapes must be wound and rewound on their reels, which takes time and creates wear. DVD discs never require rewinding -- and the search process is virtually instantaneous. DVD recordings can't be erased Videotapes can be erased within a VCR or by exposure to strong magnets. With DVD, there is no danger that contents may be accidentally erased. DVD Handycam TECHNOLOGY HANDBOOK 5 DVD MEDIA TECHNOLOGY DVD MEDIA TECHNOLOGY Although a 12cm (4-3/4") DVD is the same size as a standard CD, its high-density format allows more than 7 times more data to be recorded on a single disc. The Basic Structure of a DVD DVD consists of a dual-layered disc 12cm (4-3/4") or 8cm (3-1/8") in diameter. Each layer has a thickness of 0.6mm (1/32"). Various kinds of DVD suit the needs of various applications, such as DVD-ROM (for playback only), DVD-R (for onetime recording), and DVD-RW (for rewritable recording). ●Structure of DVD-ROM Protection Layer Record Layer Base 6 DVD Handycam TECHNOLOGY HANDBOOK DVD MEDIA TECHNOLOGY DVD-ROM for Playback Only DVD-ROM discs are for commercial prerecorded movies, computer software programs, etc. Data is stored in the form of microscopic “pits” in the record layer of the disc. These pits are scanned by a laser and then “read” as minute reflections. These minute changes in reflection are converted to signals for further processing. There are four different DVD configurations: single-sided discs with one or two recordable layers, and double-sided discs with one or two recordable layers. ●Record Layer of DVD-ROM Pit Track pitch 0.74µm DVD-R for Recording Once DVD-R discs are for recording only once. Since data recorded to disc cannot be erased, DVD-R is a good choice for data that requires long-term storage. Unlike commercially recorded DVD-ROM discs, DVD-R discs are recorded by a process of chemical change within the surface of the disc. After a DVD-R disc is recorded, data is read by the optical pickup in a manner similar to the process of reading a DVD-ROM disc; this similarity makes DVD-R recordings compatible with DVD playback units. Recorded (or “written”) areas of a disc are called “grooves”; unrecorded (or “unwritten”) area is called “land.” ●Record Layer of DVD-R Groove Land Track pitch 0.74µm DVD Handycam TECHNOLOGY HANDBOOK 7 DVD MEDIA TECHNOLOGY DVD MEDIA TECHNOLOGY DVD-RW for Repeatable Recording DVD-RW discs allow repeated recording, erasing, and re-recording of data. Data is rewritable approximately 1,000 times. This capability makes DVD-RW widely used in applications that require data editing and future updating. The recording and playback process is basically similar to the process of DVD-R recording. In the case of DVD-RW, however, the chemical change that takes place within the surface of the disc during recording is reversible, allowing data to be erased and re-recorded. DVD-RW recordings are also compatible with most DVD players. ●Record Layer of DVD-RW Groove Land Track pitch 0.74µm DVD Handycam camcorders use both DVD-R and DVD-RW discs. Discs are 8cm (3-1/8") in diameter; they can be single-sided with one recordable layer, or double-sided with one recordable layer per side. Other DVD Formats In addition to DVD-ROM, DVD-R and DVD-RW, the following DVD standards also are currently being marketed. DVD-RAM A rewritable media allowing up to 100,000 reliable rewriting operations. It cannot be played back on standard DVD players; only players supporting DVD-RAM can be used. 8 DVD+R A once-only recording media similar in capability to DVD-R. DVD+RW A rewritable media similar in capability to DVD-RW. DVD Handycam TECHNOLOGY HANDBOOK DVD MEDIA TECHNOLOGY DVD Capacity DVD-ROM, DVD-R and DVD-RW discs 12cm (4-3/4") in size, which all share the same “one layer, one side” structure, have a storage capacity of 4.7 GB -approximately 7 times larger than the capacity of a CD disc the same size. DVD Handycam camcorders use smaller DVD-R or DVD-RW discs 8mm (3-1/8") in size. 12cm (4-3/4")-diameter disc 4.7GB These smaller discs, single-sided with one recordable layer per side, have storage capacity of 1.4 GB. Small double-sided discs with one recordable layer per side are also available for DVD Handycam camcorder recording; these discs have a storage capacity of 2.8 GB -- enough to hold approximately two hours of video recording. 8cm (3-1/8")-diameter disc 1.4GB About Lasers and Lenses DVD recording uses a short-wavelength red semiconductor laser. The wavelength of this laser is 650nm (nanometers). The NA (numerical aperture) of the object lens used for optical pickup is 0.6. This combination yields a small-diameter “spotlight” and high-density recording capacity. By comparison, CD recording uses a semiconductor laser with a wavelength of 780nm and a NA of 0.45. ●Comparison of CD-ROM and DVD-ROM CD-ROM DVD-ROM the minimum pitch size 0.83µm the minimum pitch size 0.4µm diameter of spot 1.4µm Track pitch 1.6µm diameter of spot 0.9µm Track pitch 0.74µm DVD Handycam TECHNOLOGY HANDBOOK 9 DVD VIDEO RECORDING APPLICATIONS DVD VIDEO RECORDING APPLICATIONS There are two video recording applications for DVD discs: DVD-Video, offering maximum compatibility, and DVD-VR (Video Recording), for simple in-camera editing. What is an Application Standard? An application standard, such as DVD-Video or DVD-VR, is not the same as a physical standard, such as DVD-ROM, DVD-R, or DVD-RW. A physical standard refers to the disc itself; application standards refer to the recording process, and determine the recording method to be used for various purposes. For the purpose of recording video with maximum flexibility for playback compatibility, the DVD-Video application standard is used. For recording video with limited playback compatibility but additional in-camera editing, the DVD-VR (Video Recording) application standard is used. About Each Application Standard DVD-Video DVD-Video was first developed for commercial DVD movies. DVD-Video creates recordings that cannot be edited in the camcorder. It allows up to 2 hours of moving images and sound. MPEG 2 coding is used for video; Dolby AC-3 coding is used for sound. DVD-Video recordings can be played back on virtually all DVD players. DVD-VR DVD-VR modified the concept of DVD-Video, allowing user-friendly editing functions for consumer recording. DVD-VR recordings can be played back on a limited number of DVD players that support the DVD-VR application standard. ●How physical standards compare to application standards Physical standard DVD-R Application standard DVD-RW DVD-Video Although DVD-R can only be written once, it can be played back on many models of DVD player. feature DVD-VR DVD-RW is rewritable for further recording and can be initialized for re-use, even after finalizing. However, not all models of DVD player can play DVD-RW. DVD recorded in the DVD-Video standard can be played back on many models of DVD player. : Can be played back on a DVD player. 10 DVD Handycam TECHNOLOGY HANDBOOK DVD recorded in the DVD-VR standard can be edited. DVD VIDEO RECORDING APPLICATIONS Video Coding Format DVD Handycam camcorder movies recorded by the DVD-Video application standard use MPEG 2 coding to fit more data on a disc. Widely employed in communication and broadcasting, MPEG 2 offers excellent image quality and flexible data handling. Within the MPEG 2 standard, DVD-Video recordings adopt MP@ML (Main Profile at Main Level) -- a profile that provides advanced functions, at a level that maintains high-quality images. DVD Handycam camcorder recordings also use VBR (Variable Bit Rate) coding. Bit rate defines the amount of data that flows in a given period of time. High bit rates yield better images, but require an increased amount of data; low bit rates require less data, but at the expense of image quality. By varying the bit rate depending upon the visual content of each video scene, DVD-Video recording can maintain excellent image quality while minimizing the amount of data that must be recorded -- and maximizing the recording capacity of a single disc. Audio Coding Format For audio, DVD Handycam camcorders adopt the Dolby AC-3 (2-channel) format. This format provides an ideal balance between audio quality and data requirements -- and is also suitable for a wide range of channel configurations, including monaural, 2-channel stereo, and 5.1-channel surround sound applications. Another audio recording format, Linear PCM (Pulse Code Modulation), offers excellent audio quality without data compression. Although this audio format is suitable for prerecorded music, music videos, etc., its data requirements are higher. About Initializing and Finalizing “Initializing” means preparing a disc for recording. DVD-R discs do not require initializing. DVD-RW discs must be initialized, and this is done inside the DVD Handycam camcorder. Each time you insert a new or uninitialized DVD-RW disc, you will see a prompt that asks if you wish to initialize your disc. Initializing erases all previously recorded information. If your disc has already been initialized and partially recorded, it does not require initializing for subsequent recording sessions. “Finalizing” DVD-R and DVD-RW discs means preparing them for playback. In order to play back your recordings on DVD players or computers with DVD-ROM drives, you need to finalize your disc. But even without finalizing, you can always view the contents of your recording using the DVD Handycam camcorder as your playback device -- viewing scenes on your camcorder's screen, or on your TV screen by connecting direct A/V output on your camcorder to video audio inputs on your TV. Once a DVD-R disc has been finalized, no further recording is possible. DVD-RW discs, however, can be “unfinalized” and initialized again for further recording. DVD Handycam TECHNOLOGY HANDBOOK 11 THE DVD HANDYCAM CONCEPT THE DVD HANDYCAM CONCEPT Sony DVD Handycam camcorders bring unique and exciting advantages to the world of video recording. The Concept 2 1 Compatibility with DVD Players Fast Search & Access DVD-R and DVD-RW discs recorded by DVD Handycam camcorders in the DVD-Video application can be easily played back on most existing DVD players -- making DVD-Video discs compatible with most decks, computers and PlayStation 2 consoles worldwide. DVD offers many advantages over videocassette tape systems, including fast search and access to scenes by selecting thumbnail images. DVD Handycam camcorders automatically create thumbnail images during the finalization process; these images can be used for instant access to the scene you want. Thumbnail images are viewable whether you use your camcorder playback or play back scenes on your DVD player or PC computer. 3 4 Editing with a PC Movies and Still Images Data recorded on DVD Handycam camcorders can be easily played back and editing on a PC. Video can be transferred from camcorder to PC by inserting the DVD-R or DVD-RW disc into the disc drive of a PC, or by connecting the camcorder to the PC via USB. USB 2.0 provides high-speed data transfer. Both DVD-Video and DVD-VR discs can be edited. With DVD, a single media can record both movies and still images. Still images are recorded on the disc as JPEG files. DVD Handycam camcorders allow you to play an automatic, continuous “slide show” of your still images on your TV screen. Both movies and still images can be recorded on the same DVD-R or DVDRW disc. 5 6 High-Density, High-Quality Data High Fidelity Audio By adopting MPEG 2 and VBR (Variable Bit Rate) data compression, DVD Handycam recording maintains superb picture quality while permitting high-capacity recording on the disc. By using Dolby AC-3 (2-channel) audio recording, DVD Handycam camcorders provide high-quality stereo sound for lifelike realism. About Thumbnail Display DVD Handycam recorded screens are capable of displaying recorded contents in the form of thumbnail images -- six images per screen. Thumbnails can show both movies scenes and still images. These thumbnail images are automatically created when you finalize your disc. Unlike systems that only identify movies or images by time and date, thumbnail images are more useful because they give you a visual record of what each scene or still thumbnails on DVD Handycam 12 DVD Handycam TECHNOLOGY HANDBOOK image shows. Before finalizing, you can always use your DVD Handycam camcorder as your playback device using the LCD screen or by connecting the supplied AV cable to your TV. After finalizing a recorded disc, you can view dated thumbnails on your TV screen using a standard DVD player or on your PC computer screen. You can also display the title of your finalized DVD recording. thumbnails on DVD players THE DVD HANDYCAM CONCEPT Playback Compatibility The DVD Handycam camcorder recording system is based on international DVD standards, so DVD Handycam recordings can be played back on a vast universe of playback devices -- including most DVD players, personal computers with DVD drives, and PlayStation 2 video game consoles.

For video recording and playback, which requires a large amount of data, bit rate is expressed in Mbps (“megabits per second”). In general, a higher bit rate results in higher-quality picture and sound. Bit rate can also be constant or variable. ❏ Coding In a digital video or audio signal, coding (or encoding) refers to the process of converting data from one form to another -- for example, into a compressed form so more data can be recorded and stored on a DVD disc. During playback, the compressed data is decoded to its original form. ❏ Constant Bit Rate Constant Bit Rate (CBR) means that all scenes are converted at the same rate; its purpose is to simplify the coding and decoding process. ❏ Dolby AC-3 The audio system used in DVD Handycam recordings. In the Dolby AC-3 system, audio can be recorded in 2-channel stereo, monophonic, or 5.1 channel surround sound (using six speakers for front left/right, center, rear left/right, and subwoofer). Audio compression only takes place in the frequency range beyond human hearing. ❏ DVD Applications DVD is a multipurpose medium used for storing moving and still images, audio and data. Its official name is “Digital Versatile Disc.” There are various applications for DVD discs, including high-capacity storage of computer software and data. DVD video applications include DVD-Video, used for high-quality commercial recordings, and DVD-VR (Video Recording), used for personal video recordings that can be re-written (recorded more than once) and edited. ❏ DVD Capacity CD-sized DVD discs (4-3/4" or 12cm in diameter) can have one or two sides, and each side can contain one or two recordable layers. For a single-sided disc, dual-layer recording allows for up to 8.5 GB of data. For a double-sided disc, single-layer recording holds up to 9.4 GB. A doublesided disc with two recording layers can hold up to 17 GB of data. DVD Handycam camcorder use smaller 3-1/8" (8cm) discs. A double-sided DVD Handycam disc has one recording layer per side and holds up to 2.8 GB of data; it allows up to 2 hours of recording. 20 DVD Handycam TECHNOLOGY HANDBOOK ❏ DVD Formats DVD discs for video recording exist in various formats or standards. DVD-ROM is a playback-only format used for commercial movies. DVD-R is a format that can be recorded only once. DVD-RW can be recorded, edited and re-written (re-recorded). DVD-RAM, DVD+R and DVD+RW are alternate recordable formats not compatible with Sony DVD Handycam camcorders, which use only discs that conform to DVD-R and DVD-RW standards. ❏ DVD-Video The application for DVD recordings that do not require editing. DVD-Video allows up to 2 hours of high quality moving images and sound on a single disc, using MPEG 2 coding for movies and Dolby AC-3 (Dolby Digital 2-Channel) or linear PCM recording for sound. DVD-Video is an optical disc format that also allows for special playback features such as multiple screen ratios, captions, language options, and simultaneous multi-angle viewing of a scene. ❏ DVD-VR The application for which Sony DVD Handycam camcorders are designed. DVD-VR (or DVD Video Recording) provides added in-camera capabilities such as re-recording, editing, playlist display, etc. ❏ Finalizing Finalizing a disc enables its recorded contents to be played back on other equipment. Once finalized, DVD-R and DVDRW discs are read as though they were commercial recorded DVD movies -- allowing them to be played back on most DVD players. A finalized disc can no longer be re-recorded, but DVD-RW discs can be “unfinalized” to return them to recordable state. ❏ Groove/Land On a DVD disc, “groove” describes the spiral field where data is written to a recordable layer; “land” describes areas where data is not written. In the case of DVD-ROM, reading is carried out by an optical pickup following “pits” in the surface of the disc. In the case of DVD-R and DVD-RW, reading is carried out by an optical pickup following grooves in the surface of the disc. ❏ Initializing Initializing a disc allows the disc to be recorded or written on. Initializing a previously recorded disc will erase all existing data on the disc. DVD-R discs to not need to be initialized. DVD-RW discs must be initialized. The DVD Handycam camcorder system provides an “initializing” prompt each time a new DVD-RW disc is inserted. GLOSSARY ❏ Laser The DVD Handycam recording system uses a shortwavelength red semiconductor laser device to record data. This device passes current to a semiconductor and emits a strong beam of light. Gallium arsenic is used to generate the short-wavelength red laser beam that reads digital data on a DVD disc. ❏ Object Lens This lens performs two tasks: first, focusing the laser onto the disc surface; second, collecting the reflected laser light and concentrating it on the photodiode detector. The performance of the object lens largely depends on the value of its numerical aperture (NA). ❏ Pit ❏ Linear PCM Recording Linear PCM (Pulse Code Modulation) is an audio system that converts analog to digital signals without compression; it is used primarily in high fidelity music recording. DVD Handycam camcorders do not use Linear PCM recording. Pits describe the microscopic hollows within the surface of a DVD-ROM or CD-ROM disc. Data is read in a spiral motion and is determined by the length and number of pits that occur. The discs used by DVD Handycam camcorders do not have pits; instead, their data is carried by changes in reflection on the disc's surface. ❏ MPEG MPEG (Moving Pictures Experts Group) is an international group that establishes industry-wide standards for digital signal compression. These standards are known as MPEG 1, MPEG 2, MPEG 4, etc. ❏ Playlist The function that arranges movie scenes and still images on a DVD disc. Playlists can be set up for editing and playback purposes; recorded scenes and still images are not changed by being put in playlist order. ❏ MPEG 2 MPEG 2 is a digital standard for demanding video applications. It offers high quality images with data compression that reduces the amount of data that must be processed. Rather than processing complete video frames, the MPEG 2 system processes only the differences between adjacent frames. ❏ Track A data-recording field in the shape of a spiral or concentric circle. CD and DVD tracks have a spiral structure; floppy disc and hard disc tracks are concentric. The distance between adjacent tracks is called “track pitch.” ❏ Variable Bit Rate ❏ MP@ML The MPEG 2 standard allows various parameter setups for picture formats and coding modes. MP@ML (Main Profile at Main Level) is the parameter setup adopted for DVD-Video and DVD-VR (Video Recording) applications. “Profile” refers to the combination of functions provided; “Level” refers to the level of resolution and frame rate. ❏ Numerical Aperture Variable Bit Rate (VBR) changes its data conversion process depending on the amount of movement (or “dynamics”) in a given scene; its purpose is to reduce data requirements to a minimum while maintaining high image quality. ❏ Visual Index A DVD Handycam function that displays movie scenes and still images as “thumbnail” images on a multi-image screen, making it easy to find a specific scene or image for playback. Numerical Aperture (NA) value determines the performance of an object lens; the larger the value, the more data can be written at any one time. ❏ Optical Pickup This device combines a short wavelength semiconductor red laser, a pair of 45-degree mirrors, an object lens and a photodiode. In the DVD Handycam system, light emitted from the laser is bent at a 45-degree angle, passes through the object lens, reflects off the surface of the DVD disc, is concentrated by the object lens and detected by the photodiode. • Manufactured under license from Dolby Laboratories. “Dolby” and the double-D symbol are trademarks of Dolby Laboratories. • Microsoft and Windows are trademarks or registered trademarks of Microsoft Corporation in the United States and / or other countries. • PlayStation is registered trademarks of Sony Computer Entertainment Inc. • All other product names mentioned herein may be the trademarks or registered trademarks of their respective companies.
