    The authors address the buffer size requirements for a CCSDS-based packetized and multiplexed video transfer system. The objective is to minimize the delay of the video data through the buffer and at the same time maintain continuous video data flow at the output. Due to the various delays, multiplexer operation, and buffer data accumulation in the system, the buffer size must be properly chosen t... View full abstract»
