摘要： 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.

摘要： Provided are a method and apparatus for supporting a multiband wireless fidelity (WiFi). The method for supporting the multiband WIFI includes: assigning a category and a frequency band for traffic, based on one or more characteristics of the traffic; packetizing the traffic in a media access control (MAC) unit corresponding to the assigned frequency band; and transmitting the packetized traffic by using the assigned frequency band in a physical layer (PHY) unit corresponding to the assigned frequency band.
