Abstract

A system and a method transfer multiple data channels between a server and a terminal via a stream session over a network. The system and the method utilize a bitstream switching, a fast buffer filling and/or a fast playback start to facilitate a switch from a first data channel and a second data channel. The first data channel and/or the second data channel is delivered to and/or is transferred to the terminal from the server over the network via a streaming session. The server transfers second data of the second data channel to the terminal via one or more tracks which are encoded at more than one bitrate and/or are configured in one or more configurations. The terminal requests a change between the first track and/or the second track without terminating the stream session for the first data channel between the terminal and the server.
