4. Technology of video conferencing
Video conferencing system multimedia data transmission, the larger the amount of data source signal sounds and moving images, can not be transferred on the general conditions of the digital line. Based on the practical effects of the requirements,
the propagation of sound and image signal should be continuously smooth , other auxiliary functions can easy to use. Therefore, Tone image compression, communication line conditions, data sharing and other aspects of the application have high technical requirements in the sound system.
5. Trends of video conferencing
The current application of video conferencing market for all to see, but in the future there are many things need to do, in order to better apply to all areas of society. Improvements include transmission quality, integrity, cost, depending on the audio / visual. In respect of standards, Resource Reservation Protocol (RSVP) helps to avoid network congestion and ensure the transmission quality video conferencing; Although Real-time Transport Protocol (RTP) can not guarantee the integrity of data transmission, it can use the timestamp method to handle timing relationships, then the data transmission process sequence is not disrupted.
Video communication will become easier, the cost will be lower, the traditional meeting model has been far from meeting the needs of the Internet age. The video conferencing system as a support for people in real-time remote information exchanges, collaborative work system, so that members can collaborate remotely intuitive, real video/audio communication.
