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.
Claims24
A method comprising:
- receiving a current frame comprising a frame sync segment and a plurality of data segments, wherein the current frame contains a current map indicating a location of at least first and second differently coded data in a first frame, a next map indicating a location of at least first and second differently coded data in a second frame, and a count indicating the number of frames until the next map becomes the current map;
- and,
- processing the at least first and second differently coded data in the first frame in response to the current map.
A method of transmitting a current frame having a frame sync segment and a plurality of data segments comprising:
- inserting a current map, a next map, and a count into the current frame, wherein the current map indicates a location of at least first and second differently coded data in a first frame, wherein the next map indicates a location of at least first and second differently coded data in a second frame, and wherein the count indicates the number of frames until the next map becomes the current map;
- and,
- transmitting the current frame.
A method comprising:
- receiving a frame comprising first and second fields each having a frame sync segment and a plurality of data segments, wherein the first field contains a current map and count information, wherein the second field contains a next map and count information, wherein the current map indicates location of at least first and second differently coded data in a current frame, wherein the next map indicates location of at least first and second differently coded data in a future frame, and wherein the count information indicates the number of frames until the next map becomes the current map;
- and,
- processing the at least first and second differently coded data in the current frame in response to the current map.
A method of transmitting a frame having first and second fields each having a frame sync segment and a plurality of data segments comprising:
- inserting a current map and count information into the first field, wherein the current map indicates location of at least first and second differently coded data in a current frame;
- inserting a next map and count information into the second field, wherein the next map indicates location of at least first and second differently coded data in a future frame, and wherein the count information indicates the number of frames until the next map becomes the current map;
- and,
- transmitting the first and second fields of the frame.
