Abstract
A receiver receives a digital signal. The digital signal contains a frame of robust VSB data and ATSC data, and the digital signal further contains a map. The map contains information indicating a location of the robust VSB data and ATSC data in the frame. A decoder of the receiver decodes the digital signal. A processor of the receiver processes at least one of the robust VSB data and the ATSC data according to the location information contained in the map.
Claims77
A method comprising:
- receiving a digital signal, wherein the digital signal contains robust VSB data, and wherein the digital signal further contains a map permitting a receiver to process the robust VSB data, wherein the robust VSB data contains a duplicate of the map;
- and,
- processing the robust VSB data and the duplicate of the map in response to the map.
An apparatus comprising:
- a receiver that receives a digital signal, wherein the digital signal contains a frame of first and second 8 VSB data, wherein the first and second 8 VSB data have different bit rates, wherein the digital signal further contains a map, wherein the map contains information indicating a location of at least one of the first and second 8 VSB data in the frame;
- a decoder that decodes the digital signal;
- and,
- a processor that processes the first 8 VSB data according to the location information contained in the map.
An electrical signal comprising a map, first data symbols, and second data symbols, wherein the first and second data symbols have the same constellation, wherein the first and second data symbols have different bit rates, wherein the first and second data symbols are intermixed in a data frame, and wherein the map contains information indicating a location of at least one of the first and second 8 VSB data in the electrical signal.
An apparatus comprising
- a receiver that receives a digital signal, wherein the digital signal contains a frame of first and second 8 VSB data, wherein the first and second 8 VSB data have the same constellation, wherein the first and second 8 VSB data have different bit rates, wherein the digital signal further contains a map, wherein the map contains information indicating a location of the first 8 VSB data in the frame;
- a decoder that decodes the digital signal;
- and,
- a processor that discards the second VSB data and that processes the first 8 VSB data.
An apparatus comprising:
- a receiver that receives a digital signal, wherein the digital signal contains a frame of robust VSB data, ATSC data, or both, wherein at least the ATSC data has PID numbers associated therewith, wherein the digital signal further contains a map, wherein the map contains information indicating a location of the robust VSB data in the frame;
- a first processor that processes the robust VSB data based upon the map;
- and,
- a second processor that processes the ATSC data based upon PID numbers.
