Abstract
According to an embodiment of the present disclosure, there is provided a method and apparatus for transmitting/receiving a digital broadcast. The method for transmitting a digital broadcast, the method comprising: configuring AV data; configuring broadcast data; configuring application signaling information (ASI) by considering at least one of the AV data and the broadcast data or combination thereof; configuring an MPEG-based transport stream by multiplexing the AV data, the broadcast data and the ASI; and transmitting the MPEG-based transport stream, wherein the ASI includes data for driving an application executed by a broadcast receiver.
Claims19
A method for transmitting a digital broadcast, the method comprising:
- configuring AV data;
- configuring broadcast data;
- configuring application signaling information (ASI) by considering at least one of the AV data and the broadcast data or combination thereof,
- configuring an MPEG-based transport stream by multiplexing the AV data, the broadcast data and the ASI;
- and
- transmitting the MPEG-based transport stream,
- wherein the ASI includes data for driving an application executed by a broadcast receiver.
A method for receiving a digital broadcast, the method comprising:
- distinguishing AV data, broadcast data and application signaling information (ASI) by receiving an MPEG-based transport stream and demultiplexing the transport stream;
- processing the AV data;
- processing the broadcast data;
- and
- checking the ASI and driving an application based on information in the ASI.
An apparatus for transmitting a digital broadcast, the apparatus comprising:
- an AV data configuration unit configured to configure AV data;
- a broadcast data generator configured to configure broadcast data;
- an application signaling information (ASI) configuration unit configured to configure ASI by considering at least one of the AV data and the broadcast data;
- a multiplexer configured to configure an MPEG-based transport stream by multiplexing the AV data, the broadcast data and the ASI;
- and
- a data transmitter configured to transmit the MPEG-based transport stream,
- wherein the ASI includes data for driving an application executed by a broadcast receiver.
