Paper Abstract

It is highly desirable for many broadcast video applications to be able to provide support for many diverse user devices, such as devices supporting different resolutions, without incurring the bitrate penalty of simulcast encoding. On the other hand, video decoding is a very complex operation, while the complexity is very dependent on the resolution of the coded video. Low power portable devices typically have very strict complexity restrictions and reduced-resolution displays. For such environments total bitrate efficiency of combined layers is an important requirement, but the bitrate efficiency of a lower layer individually, although desired, is not a requirement. In this paper, we propose a complexity constrained scalable system, based on the Reduced Resolution Update mode that enables low decoding complexity, while achieving better Rate-Distortion performance than an equivalent simulcast based system. Our system is targeted on broadcast environment with some terminals having very limited computational and power resources.
