SVC enables high flexibility for implementation and optimization in various application scenarios. It provides a
In video conferencing, efficient scalable video coding provides certain benefits in the transmission of video streaming. For example, a video conference with heterogeneous clients where multiple bit streams of the same video content differing in picture size, frame rate and bit rate should be provided simultaneously. An SVC solution could make use of simulcasting, in which multiple SVC streams are made available to the different clients, allowing each client to select the picture size, frame rate, and bit rate that best suits its needs. This provides a scalable bit stream set from which representations with lower resolution or quality can be obtained. A video client with restricted resources such as display resolution, processing power, or battery power, needs to decode the lowest available bit stream.
