In the alternate format of high-definition video mode, known as 1080p, the p would stand for progressive scan. 1080i is generally used in place of 1440x1080, at a frame rate of 29.97 (30000/1001), while 1080p is usually used in place of 1920x1080 (full HD), at a frame rate of 23.976 fps (24000/1001). 1080p 1080p is the shorthand name for a category of HDTV video modes. The number 1080 represents 1,080 lines of vertical resolution (1,080 horizontal scan lines), while the letter p stands for progressive scan (meaning the image is not interlaced). 1080p can be referred to as full HD or full high definition although 1080i is also "Full HD" (1920x1080 pixels). The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels. This creates a frame resolution of 1920×1080, or 2,073,600 pixels in total. The frame rate in hertz can be either implied by the context or specified after the letter p (or i), such as 1080p30, meaning 30 Hz. 2 panes Users see two sites on one monitor in two panes. The two panes are of the same size. Each pane is about 1/4 of the screen. Use 2-pane as an adjective. 2CIF 2CIF defines a video with a resolution of 352 × 576 pixels and using progressive scanning. 2SIF 2SIF defines a video with a resolution of 352 × 480 pixels and using progressive scanning. 3 panes Users see three sites on one monitor in three panes. Each pane is about 1/3 of the screen. Use 3-pane as an adjective. 4CIF 4CIF defines a video resolution of 704 ×576 pixels. 4SIF 4SIF defines a video with a resolution of 704 × 480 pixels and using progressive scanning. 720p 720p is the shorthand name for a category of HDTV video modes. The number 720 stands for the 720 horizontal scan lines of display Issue 01 (2013-03-27) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 129 HUAWEI TE30 Videoconferencing Endpoint User Guide E Terminology resolution (also known as 720 pixels of vertical resolution), while the letter p stands for progressive scan or non-interlaced. When broadcast at 60 frames per second, 720p features the highest temporal (motion) resolution possible under the ATSC standard. Progressive scanning reduces the need to prevent flicker by filtering out fine details, so sharpness is much closer to 1080i than the number of scan lines would suggest. broadcast (site) All sites, except for the site being broadcast, view the site that is broadcast. On the Broadcast Site screen, users can choose between Broadcast Single and Broadcast in Turn. broadcast single (site) Broadcast one specified site. built-in MCU An built-in unit of an endpoint, using the built-in MCU, the endpoint can hold a multipoint conference that supports multiple functions, such as site access, video exchange, audio mixing, data processing, and signaling interaction. call absent (sites) Place calls to all the sites that are on the site list but are absent from the conference. call site Place a call to a site to add the site to the conference. cascading Multiple MCUs are connected in series at different layers to allow the number of participants to expand beyond what a single MCU can support. In cascading mode, an MCU in an upper layer can control an MCU in a lower layer. camera preset Users can control a camera by zooming, panning, and tilting the camera or changing the focus. Then, users can store this camera position and assign a number to this position. This preset position is a camera preset. During a conference, users can move the camera to a camera preset by selecting the relevant number. CIF CIF (Common Intermediate Format), also known as FCIF (Full Common Intermediate Format), is a format used to standardize the horizontal and vertical resolutions in pixels of YCbCr sequences in video signals, commonly used in video teleconferencing systems. It was first proposed in the H.261 standard. continuous presence A feature in multi-point conferencing that allows the video endpoint to see images from multiple video endpoints at the same time. All parties remain continuously visible or 'present' for the duration of the call and the user can have control over the screen layout. Continuous presence is better suited for team collaboration since it allows participants to see the reactions (body language) of all participants, not just the speaker. Issue 01 (2013-03-27) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 130 HUAWEI TE30 Videoconferencing Endpoint User Guide E Terminology delete site Remove a site from the site list. dual stream During a conference, two channels of video streams can be sent or received simultaneously. For example, one channel is used for transmitting video (such as video captured by a camera) and the other channel is used for transmitting presentation (such as a computer desktop). The two channels of videos can be displayed on two displays. end conference End a conference. In this case, all sites leave the conference. full-duplex A full-duplex, or sometimes double-duplex system, allows communication in both directions, and, unlike half-duplex, allows this to happen simultaneously. Land-line telephone networks are full-duplex, since they allow both callers to speak and be heard at the same time. A good analogy for a full-duplex system would be a two-lane road with one lane for each direction. G.711 G.711, also known as Pulse Code Modulation (PCM), is a very commonly used waveform codec. G.711 uses a sampling rate of 8,000 samples per second, with the tolerance on that rate 50 parts per million (ppm). Non-uniform quantization (logarithmic) with 8 bits is used to represent each sample, resulting in a 64 kbit/s bit rate. There are two slightly different versions; μ-law, which is used primarily in North America, and A-law, which is in use in most other countries outside North America. G.722 G.722 is a ITU-T standard 7 kHz wideband speech codec operating at 48, 56 and 64 kbit/s. It was approved by ITU-T in November 1988. Technology of the codec is based on sub-band ADPCM (SB-ADPCM). G.728 G.728 is an ITU-T standard for speech coding operating at 16 kbit/s. It is officially described as Coding of speech at 16 kbit/s using low-delay code excited linear prediction. give floor After the chair site gives floor to a site, the other sites view and hear the site. All the sites, except the chair site and the site that is given the floor, are muted. H.239 H.239 is an ITU-T recommendation from the H.32x Multimedia Communications' macrofamily of standards for multimedia communications over various networks. The H.239 recommendation is titled "Role management and additional media channels for Issue 01 (2013-03-27) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 131 HUAWEI TE30 Videoconferencing Endpoint User Guide E Terminology H.3xx-series terminals". Practical importance of this recommendation is its setting forth a way to have multiple video channels (for example, one for conferencing, another for presentation) within a single session (call). H.261 H.261 is a 1990 ITU-T video coding standard originally designed for transmission over ISDN lines on which data rates are multiples of 64 kbit/s. It is one member of the H.26x family of video coding standards in the domain of the ITU-T Video Coding Experts Group (VCEG). The coding algorithm was designed to be able to operate at video bit rates between 40 kbit/s and 2 Mbit/s. The standard supports two video frame sizes: CIF (352x288 luma with 176x144 chroma) and QCIF (176x144 with 88x72 chroma) using a 4:2:0 sampling scheme. It also has a backward-compatible trick for sending still picture graphics with 704x576 luma resolution and 352x288 chroma resolution (which was added in a later revision in 1993). H.263 H.263 is a video codec standard originally designed as a low-bitrate compressed format for videoconferencing. It was developed by the ITU-T Video Coding Experts Group (VCEG) in a project ending in 1995/1996 as one member of the H.26x family of video coding standards in the domain of the ITU-T. H.263v2 (H.263+) added support for flexible customized picture formats and custom picture clock frequencies. Previously the only picture formats supported in H.263 had been Sub-QCIF, QCIF, CIF, 4CIF, and 16CIF, and the only picture clock frequency had been 30000/1001 (approximately 29.97) clock ticks per second. H.264 H.264/AVC/MPEG-4 Part 10 (Advanced Video Coding) is a standard for video compression. The final drafting work on the first version of the standard was completed in May 2003. H.264/AVC is the latest block-oriented motion-compensation-based codec standard developed by the ITU-T Video Coding Experts Group (VCEG) together with the ISO/IEC Moving Picture Experts Group (MPEG), and it was the product of a partnership effort known as the Joint Video Team (JVT). The ITU-T H.264 standard and the ISO/IEC MPEG-4 AVC standard (formally, ISO/IEC 14496-10 - MPEG-4 Part 10, Advanced Video Coding) are jointly maintained so that they have identical technical content. H.264 is used in such applications as Blu-ray Disc, videos from YouTube and the iTunes Store, DVB broadcast, direct-broadcast satellite television service, cable television services, and real-time videoconferencing. H.323 H.323 is a recommendation from the ITU Telecommunication Standardization Sector (ITU-T) that defines the protocols to provide audio-visual communication sessions on any packet network. The H.323 standard addresses call signaling and control, multimedia transport and control, and bandwidth control for point-to-point and multi-point conferences. half-duplex A transmitting mode in which a half-duplex system provides for communication in both directions, but only one direction at a time (not simultaneously). Typically, once a party begins receiving a signal, it must wait for the transmitter to stop transmitting, before replying. hang up (site) Hang up a remote site and remove the site from the conference. Issue 01 (2013-03-27) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 132 HUAWEI TE30 Videoconferencing Endpoint User Guide E Terminology HD Refers to a video system of higher resolution than standard-definition (SD) video, most commonly at display resolutions of 1280×720 (720p) or 1920×1080 (1080i or 1080p, full HD). High definition (HD) refers to an the increase in display or visual resolution of television formats (HDTV), high definition video (used in HDTV broadcasting, digital film and computer HD video film formats), high definition multimedia interface (HDMI), an all-digital audio and video interface capable of transmitting uncompressed streams and other formats for recording and transmitting visual and audio communications. hide video During a conference, a site can hide its video to prevent other sites from viewing the video of the site. intelligent mode A video transforming mode, in this mode, cut the video first and then stretch the video. Ensure that the aspect ratio of the video remains unchanged. For example, to change wide-screen video to narrow-screen video, cut the left and right sides of the wide-screen video, and then stretch the video to full screen. lock conference (presentation) After the chair site locks a conference and if site A is sharing presentation, the other sites in the conference cannot share presentation until site A stops sharing presentation. lock site (presentation) After the chair site locks the presentation, only the site that is currently sharing the presentation can continue sharing presentation. Other sites cannot share presentation. presentation During a conference, the local site can share the content input by a computer with remote sites, such as an excel file, a diagram, or a presentation. release chair Pass the chair control to another site. request chair Request chair rights and become the chair site. request floor Request to speak. During a conference, users can request the floor from the chair site. revoke chair After the chair rights are revoked, there is no chair site in the conference. If the site that revokes the chair rights wants to become the chair site, the site needs to request chair rights. revoke presentation After the chair site revokes the presentation token, the relevant site stop sharing the presentation. Issue 01 (2013-03-27) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 133 HUAWEI TE30 Videoconferencing Endpoint User Guide E Terminology S-Video Separate Video[1], more commonly known as S-Video, also called Y/C, and sometimes incorrectly [2] referred to as Super Video[3], is an analog video signal that carries video data as two separate signals: luma (luminance) and chroma (color). This differs from composite video, which carries picture information as a single lower-quality signal, and component video, which carries picture information as three separate higher-quality signals. S-Video carries standard definition video (typically at 480i or 576i resolution), but does not carry audio on the same cable. SIF Source Input Format (SIF) defined in MPEG-1, is a video format that was developed to allow the storage and transmission of digital video. 625/50 SIF format (PAL/SECAM) has a resolution of (360 or) 352 x 288 active pixels and a refresh rate of 25 frames per second. 525/59.94 SIF Format (NTSC) has a resolution of (360 or) 352 x 240 active pixels and a refresh rate of 29.97 frames per second. site group A group of conference sites. If certain sites attend a conference frequently, users can define these sites as a group to facilitate site management. start presentation Start sharing local-site presentation with remote sites. stop broadcasting (site) Stop broadcasting a site. The other sites stop viewing the site. stop presentation Stop sharing local-site presentation with remote sites. SVGA Super Video Graphics Array or Ultra Video Graphics Array, almost always abbreviated to Super VGA, Ultra VGA or just SVGA or UVGA is a broad term that covers a wide range of computer display standards. Originally, it was an extension to the VGA standard first released by IBM in 1987. Unlike VGA—a purely IBM-defined standard—Super VGA was defined by the Video Electronics Standards Association (VESA), an open consortium set up to promote interoperability and define standards. When used as a resolution specification, in contrast to VGA or XGA for example, the term SVGA normally refers to a resolution of 800 × 600 pixels. video The video is generally output from the HD OUT 1 interface of an HD video terminal and is captured by a camera. view single (site) View any site. view site View any site. On the View Site screen, users can choose between View Single and View in Turn. voice activation This function is used for discussion or arguing scenarios. The site with the loudest voice is broadcast. XGA XGA, the Extended Graphics Array, is an IBM display standard Issue 01 (2013-03-27) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 134 HUAWEI TE30 Videoconferencing Endpoint User Guide E Terminology introduced in 1990. Today, it is the most common appellation of the 1024×768 pixels display resolution, but the official definition is broader than that.
