  • Patent number: 8953580
    Abstract: Provided is a method of processing and transmitting transport stream packets and processing the transmitted transport stream packets. A time stamp is generated in a medium access control (MAC) layer based on time information managed by the MAC layer, and a data frame including the transport stream packets is retransmitted based on an algorithm different from that used for a general data frame when a transmission error occurs. Therefore, there is no need to transmit and receive additional synchronization packets in order to precisely transmit the transport stream packets between transmitting and receiving terminals, and it is possible to reduce performance deterioration caused by latency and jitter.
