Home > FAQs Video Conferencing FAQs Videoconferencing is a method of communication using electronic devices to provide live video and audio between two or more sites. The conferences may be between individuals or groups at each site. Videoconferencing enables people to interact and call meetings at a moments notice between distant parties. They can talk through ideas and exchange information as if they were in the same room. The result is increased productivity and reduced costs. This is partly due to fewer travel, accommodation and entertainment expenses, but more importantly because of the time saved by not travelling to meetings. video conferencing enables faster decision-making. Videoconferencing allows you to meet for scheduled or unscheduled meetings, crisis resolution, interviews and design meetings. It also allows you to meet clients or suppliers, distribute expertise more effectively, run training courses, and play a video tape via remote vision. video conferencing enables you to show objects, documents, photos and high res still images. You can also share printed documents, electronic whiteboards, give a PowerPoint presentation and record the entire meeting on video. With Sony video conferencing , you can do virtually everything you do in a face-to-face meeting. A basic video conferencing system includes a Video camera, microphone, CODEC, video monitor, speaker and network connection. Sony's Multipoint software allows up to 10 sites to meet together at a moments notice using an ISDN and / or IP network. A standard telephone call can also participate. If more than 10 sites are required, then these can be connected via an external service provider. Only one unit requires the multipoint software and the other participants just need a standards compliant videoconference system to participate. Two units require the multipoint software and the other participants need a standards compliant videoconference system to participate. The two units with multipoint software are cascaded (connected) together with up to an four additional systems connected to each of them. A CODEC is the equipment that processes the video and audio signals and manages the communications. The CODEC converts analogue audio and video signals to digital signals and than compresses and transmitts these to the distant site where they are decoded, expanded and played out on the monitor and
speakers. ISDN (Integrated Services Digital Network) is just like a telephone line, but is fully digital so you get a guaranteed data rate. ISDN is available virtually everywhere in the world. Calls are charged based on time and distance. For video conferencing on ISDN, look for compliance with the H.320 standard or over your IP network look for compliance with the H.323 standard. This ensures connectivity, pictures (H.261) and sound (G.711). Extra features included as options under H.320 & H.323 include far end camera control and input selection (H.281), better audio quality (G.722 and G.728) and better video quality (H.263 or H.264). For Dual stream the new standard is (H.239). Most video conferencing systems support at least one extra (auxiliary) video input, apart from the main camera. This input can be used to connect a document camera so that you can include hardcopy documents, objects, OHP slides, printed photos, medical images or 35mm slides into your video meetings. You can also connect a VCR or Handycam to replay video footage. Sony video conferencing systems also include a memory stick slot to store and transmit presentations in the form of JPEG images from a PC or photos from your digital camera. You can also record the video meeting on a VCR for reference later. There are several ways to do this including:
