Abstract
Methods and apparatus for transmitting and receiving broadcast signals are provided. The method for transmitting a broadcast signal includes encoding mobile data for forward error correction (FEC), encoding signaling data, forming data groups including the encoded mobile data and the encoded signaling data and transmitting a signal frame that includes the data groups.
Claims20
A method of processing broadcast data in a digital transmitter, the method comprising:
- generating a broadcast signal including a frame,
- wherein the frame includes first signaling data, second signaling data, third signaling data and service data for a service,
- wherein the first signaling data includes first information for identifying the service and second information for indicating whether the service is hidden or not,
- wherein the second signaling data is used to provide service acquisition information for the service,
- wherein the second signaling data is carried in a dedicated channel identified by a unique value,
- wherein the second signaling data includes third information for identifying the service and fourth information for indicating whether the service is active or inactive,
- wherein the frame is composed of multiple sub-frames,
- wherein the multiple sub-frames are concatenated in the frame, and
- wherein the third signaling data includes fifth information related to the first signaling data and sixth information related to the multiple sub-frames;
- and
- transmitting the broadcast signal.
