Apparatus for transmitting/receiving bitstream in network and method thereof

If by a video bitstream in a communication network to the two logic channels during transmission of the communication has been established, this has to efficient use of the two channels a bit stream reception apparatus and method for reliably transmitting a video bit stream are disclosed. The invention process and transmitting process of encoding into a bitstream according to the source to the predetermined coding type, while transmitting the coded bit stream in the process, each layer of the communications protocol adds a header information of each protocol to a payload, the It includes separate from the bit stream transmitted in the process the step of transmitting the header information.
