![HUAWEI TE30 Videoconferencing Endpoint User Guide 12 Troubleshooting Issue 01 (2013-03-27) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 95 Problem Possible Cause Solution local video but not the remote video. value of Video bandwidth[frame rate] is 0, no video is sent from the remote site. administrator to solve this problem. If the remote video is displayed as a blue screen, the remote site hides its video by sending a blue screen. Contact the remote site administrator to solve this problem. The video output port is set to display the local video. Set the video output port to display the remote video. The local video is in black and white or blinks in black and white. The mode of the video output port is set incorrectly. Ensure that the mode of the video output port and the cable in use match each other. Check that the cable is connected correctly. Replace the cable if necessary. While the TE30 is in a conference, the remote video is not clear. For example, there is artifacts, frozen image, or discontinuity in the video output. Faults exist on the local video module: Perform a local video loopback test. If the video quality is poor, faults exist on the local video module. Send the TE30 to the local distributor for maintenance. The remote camera is set to focus on a near or far scene: When the remote camera is not set to focus automatically and the scene captured by a remote camera is changed, the captured video is of poor quality. Set the remote camera to focus automatically. When the conference rate is lower than 256 kbit/s, the audio protocol is set incorrectly. For example, you can access the Status screen. If the conference rate is 256 kbit/s and the audio bandwidth is 64 kbit/s, the video bandwidth will be only 196 kbit/s. In this case, the video quality is poor. If the conference rate is lower than 256 kbit/s, set the audio protocol to G.728 to reduce the bandwidth used for audio transmission. Low video bandwidth is available for the local site because the network is busy. Do not initiate conferences in busy hours of the network. Certain data is lost during transmission, because the quality of a network connection device such as an Replace the relevant network connection device.](https://usermanual.wiki/Huawei-Technologies/TE30/User-Guide-1940089-Page-103.png)
![HUAWEI TE30 Videoconferencing Endpoint User Guide E Terminology Issue 01 (2013-03-27) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. 134 S 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.
