Abstract
In a local storage and playback broadcast system, multiple copies of one or more processing parameters used in individual receivers for the local storage and playback are broadcast. In some embodiments each processing parameter is associated with each packet in the program so that a copy of each parameter is broadcast with each packet. In some embodiments the program is divided into segments, each segment having a header, and a copy of the parameter is broadcast in each segment header.
Claims34
A wireless broadcast signal comprising:
- audio program information broadcast for local storage and playback in a receiver, wherein the program information is divided into a plurality of fixed length data units;
- and
- multiple copies of a processing parameter, wherein the processing parameter is defined for use by the receiver during local storage or playback of the program information, and at least one copy of the processing parameter is associated with each data unit in the plurality of data units.
A method of transmitting information comprising:
- defining program information for transmission to a receiver;
- dividing the program information into a plurality of fixed length data units;
- defining a processing parameter for use by the receiver during subsequent local storage or playback of the program information by the receiver;
- associating the processing parameter with each data unit in the plurality of data units;
- and
- broadcasting to the receiver a wireless signal containing each fixed length data unit and the processing parameter associated with each data unit, such that one copy of the processing parameter is broadcast for each data unit broadcast.
A receiver comprising:
- a logic unit;
- a memory electrically coupled to the logic unit;
- a receiver unit electrically coupled to the logic unit;
- and
- an output unit electrically coupled to the logic unit;
- wherein the receiver unit is configured to receive a wireless signal that includes program information divided into a plurality of fixed length data units and that further includes at least one copy of a particular processing parameter associated with each data unit in the plurality of data units;
- and
- wherein the logic unit is configured to use the processing parameter during subsequent local storage in the memory or playback of the program information. The receiver of claim 27, wherein the signal further includes a plurality of frames, wherein each frame includes a unique frame header and one or more of the data units, and wherein each frame header includes at least one copy of the processing parameter associated with each data unit in each frame.
