EXECUTION OF WAIT-AND-SEE DATA ON STATISTIC MULTIPLEX TRANSMISSION ENCODER

摘要

PROBLEM TO BE SOLVED: To obtain a method and a system that provide a wait-and-see data capability to an existing statistic multiplex transmission encoder platform such as a multi-channel video data encoder. ;SOLUTION: The encoder is provided with a wait-and-see data processor 160 as a plug-in card or an external device connected to an existing multi-channel encoder 170. The wait-and-see data processor is connected to a quantization level processor 130 and a packet multiplexer 140 in the multi-channel encoder as if the wait-and-see data processor were another multi-channel encoder. The wait-and-see data processor executes a special rate control method by encoding data and transmitting the encoded data to a PM only when a global quantization level QL indicates that a spare bandwidth is valid. It is assumed that the spare bandwidth is valid when the global quantization level QL is lower than a threshold value.;COPYRIGHT: (C)2001,JPO
