Abstract: A method of identifying a parameter set for decoding a multi-layer video representation. The method includes identifying the parameter set based on a parameter set identifier and one or more layer identifiers indicating a layer of the video representation. Optionally, the method may further include returning the identified parameter set from a parameter set database, and activating the parameter set. Identifying parameter sets using both a parameter set identifier and one or more layer identifiers is advantageous in that the length of the parameter set identifier codeword may be shorter. This results in bitrate savings, since the number of bits which need to be transmitted is reduced. Corresponding computer program products and video decoders for decoding a multi-layer video representation are disclosed.

Abstract: A method and system for gracefully reducing demands for shared decompression resources required to present multiple video streams concurrently such that their streaming video content is simultaneously available for further processing or display. In particular, it relates to the use of presentation time stamps or incoming frames with reference to a time base dock and a threshold to determine if the decompression resources are falling behind in their ability to process incoming frames in real time. If this occurs then frames are dropped, i.e. discarded without being decompressed, with preference given to dropping incremental frames rather than key frames.
