Media gateway

Abstract

A 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 AID 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.

What is claimed is: 
     
         1 . A media gateway, comprising:
 a receiver configured to receive a first content file of a first standard and a second content file of a second standard different from the first standard, to divide the first content file into a first video signal and a first audio signal, and to divide the second content file into a second video signal and a second audio signal;   a video decoder configured to decode the first and second video signals;   an audio converter configured to convert the first and second audio signals;   an encoder configured to encode the converted first audio signal and the decoded first video signal into a first streaming signal of a third standard, and to encode the converted second audio signal and the decoded second video signal into a second streaming signal of the third standard; and   a data communication unit configured to transmit the encoded streaming signals of the third standard to a client device for display on the client device.   
     
     
         2 . The media gateway of  claim 1 , wherein the first standard corresponds to a different encoding from the second standard. 
     
     
         3 . The media gateway of  claim 1 , wherein the first and second video signals are decoded into first and second displayable image signals, respectively. 
     
     
         4 . The media gateway of  claim 1 , wherein the first and second audio signals are converted into first and second digital audio signals, respectively. 
     
     
         5 . The media gateway of  claim 1 , wherein the signal receiver is configured to select one of the first streaming signal of the third standard or the second streaming signal of the third standard to be transmitted to the client device. 
     
     
         6 . The media gateway of  claim 1 , further comprising:
 a controller configured to retrieve a representative image of at least one of the first and second content files.   
     
     
         7 . The media gateway of  claim 6 , wherein the data communication unit is further configured to transmit, to the client device for display on the client device, the representative image of at least one of the first and second content files. 
     
     
         8 . The media gateway of  claim 1 , wherein the receiver is configured to receive the first content file from a first source and the second content file from a second source different from the first source. 
     
     
         9 . A media gateway, comprising:
 a receiver configured to receive first content data and a second content data from different sources, to divide the first content data into a first video signal and a first audio signal, and to divide the second content data into a second video signal and a second audio signal;   a video decoder configured to decode the first and second video signals;   an audio converter configured to convert the first and second audio signals;   an encoder configured to encode the converted first audio signal and the decoded first video signal into a first streaming signal, and to encode the converted second audio signal and the decoded second video signal into a second streaming signal; and   a data communication unit configured to transmit the encoded streaming signals to a client device for display on the client device.   
     
     
         10 . The media gateway of  claim 9 , wherein the first and second video signals are decoded into first and second displayable image signals, respectively. 
     
     
         11 . The media gateway of  claim 9 , wherein the first and second audio signals are converted into first and second digital audio signals, respectively. 
     
     
         12 . The media gateway of  claim 9 , further comprising:
 a controller configured to retrieve a representative image corresponding to at least one of the first and second content data.   
     
     
         13 . The media gateway of  claim 12 , wherein the data communication unit is further configured to transmit, to the client device for display on the client device, the representative image of the at least one of the first and second content data. 
     
     
         14 . A media gateway, comprising:
 a receiver configured to receive first content data having a first file format and a second content data having a second file format, to divide the first content data into a first video signal and a first audio signal, and to divide the second content data into a second video signal and a second audio signal;   a video decoder configured to decode the first and second video signals;   an audio converter configured to convert the first and second audio signals;   an encoder configured to encode the converted first audio signal and the decoded first video signal into a first content signal, and to encode the converted second audio signal and the decoded second video signal into a second content signal, the first and second content signals having the same file format; and   a data communication unit configured to transmit at least one of the first and second content signals to a client device for display on the client device.
