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. |
