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.
Claims16
A method for processing broadcast data in a digital transmitter, the method comprising:
- generating a broadcast signal,
- wherein the broadcast signal includes first signaling data, second signaling data and service data for a service, further the service data is carried via at least one collection of at least one data channel,
- wherein the first signaling data includes first information for identifying the at least one collection of the at least one data channel,
- wherein the at least one collection includes a service signaling channel carrying the second signaling data, further the second signaling data is used to provide service acquisition information for the service,
- wherein the service signaling channel is a dedicated channel identified by a pre-assigned value,
- wherein the second signaling data includes second information for identifying the service, and third information for indicating whether the service is active or inactive;
- and
- transmitting the broadcast signal.
