摘要： Disclosed is a media gateway that processes AV signals offered over various channels into AV stream data and wirelessly transmits the AV stream data to a client such as PC or TV The media gateway includes: a broadcast signal receiver for selecting a broadcast signal and dividing the selected broadcast signal into video and audio signals; a video decoder for decoding the video signal into a displayable image signal; an A/D converter for digitally converting the audio signal; an encoder for encoding the digitally converted audio signal and the image signal; a data communication unit for transmitting/receiving AV stream data and a client control command to/from a data communication unit on a client side; and a main processor for controlling a tuner in the broadcast signal receiver according to a client control command conforming to HTTP standards received through the data communication unit and transmitting AV stream data obtained by encoding a broadcast signal of a channel selected by the tuner to a client side.
