Method and apparatus for adaptive streaming using scalable video coding scheme

A method for receiving a video streaming service, the method comprising:

• transmitting bit rate information including a bit rate decodable in a terminal, to a server;
• receiving layer information and layer data corresponding to a layer selected by the server, from the server to decode a video corresponding to the bit rate decodable in the terminal;
• and
• decoding the video corresponding to the bit rate decodable in the terminal, by using the layer information and the layer data, in which the layer selected by the server is selected from among the layer data generated for the corresponding video in accordance with a layer coding scheme using residual data.

An apparatus which provides a video streaming service, the apparatus comprising:

• a scalable coding unit which generates layer data for a corresponding video in accordance with a layer coding scheme using residual data;
• a controller which receives bit rate information including a bit rate decodable in a terminal, from the terminal and which selects a layer for decoding a video corresponding to the decodable bit rate from among the generated layer data;
• and
• a multiplexer which multiplexes layer information and layer data corresponding to the selected layer and which transmits the multiplexed layer information and layer data to the terminal.

An apparatus which receives a video streaming service, the apparatus comprising:

• a controller which transmits bit rate information including a bit rate decodable in a terminal, to a server;
• a demultiplexer which receives and demultiplexes layer information and layer data corresponding to a layer selected by the server, from the server to decode a video corresponding to the bit rate decodable in the terminal;
• and
• a scalable decoding unit which decodes the video corresponding to the bit rate decodable in the terminal by using the layer information and the layer data,
• in which the layer selected by the server is selected from among the layer data generated for the corresponding video in accordance with a layer coding scheme using residual data.
