Method and system for switching between video streams in a continuous presence conference

Номер: CN102957893A
Автор: Halavy Avishay, Be Ery Efrat, Harel Erez
Принадлежит:

An MRC system includes an MRM and an MRE that handle needs for Intra frames in an efficient way, improves the conferees experience, and reduces the load on the resources associated with that MRC videoconference by reducing the number of Intra frames and lowering the impact of Intra frames when they are needed. In some embodiments, when a requiring MRE requests an Intra frame for a video stream received from a presenting MRE, an MRM may respond by requesting the presenting MRE to send a temporary video stream toward the requiring MRE while sending in parallel a normal stream toward the rest of the MREs.
