Abstract
A transmission system includes a multiplexing apparatus and a message authentication code generating apparatus. The multiplexing apparatus multiplexes MMTP packets for video data and audio data to be transmitted to generate multiplexed data. The message authentication code generating apparatus generates a message authentication code in accordance with a message authentication scheme, using data except for at least either a time stamp or a packet counter in the MMTP packet included in the multiplexed data. The message authentication code generating apparatus adds the message authentication code to the MMTP packet.
