The objective of this document is to describe a new video complexity verifier (VCV). This verifier, when used as a part of the Hypothetical Reference Decoder (HRD), characterizes the amount of delay and buffer-size that is needed to decode and present a given bit stream at a certain level of computational capacity at the decoder. The VCV model proposed by Nokia is extended and integrated with the Video Buffer Verifier (VBV) specified by the current HRD. In addition to reducing the level of computational capacity required at the receiver to decode the bit stream, the new VCV model allows the bit stream to be decoded at multiple decoding speeds. These advantages are achieved at the cost of introducing further delay, while additional memory may often be unnecessary. Simulation results illustrate these gains.
