摘要
A play-out apparatus and method for switching a channel in a digital multimedia broadcasting receiver are provided which can decrease a delay occurring in a channel switching time. A demultiplexer demultiplexes a signal received from a transmitter and outputs video data. A time stamp adapter changes a time stamp for indicating a play-out time of the video data such that the video data can be immediately output from a playback buffer without a Coder-Decoder (CODEC) delay, and outputs the video data including the changed time stamp. The playback buffer buffers and outputs the video data output from the time stamp adapter according to the changed time stamp. A video decoder decodes and outputs the video data output from the playback buffer according to the changed time stamp. A display unit plays the decoded video data out.
