Abstract
A transmitting device for communicating via a multimedia communication link includes a compression circuitry that receives blanking period data corresponding to blanking states of video blanking periods. The compression circuitry compresses the blanking period data into compressed blanking period data. The transmitting device also includes an interface that transmits signals corresponding to the compressed blanking period data via one or more multimedia channels of the multimedia communication link.
Claims20
A transmitting device for communicating via a multimedia communication link, the transmitting device comprising:
- a circuit to receive data island data that includes at least one of auxiliary data or audio data;
- a compression circuit to receive blanking period data describing video blanking states, the compression circuit to compress the blanking period data into compressed blanking period data but not to compress the data island data;
- and
- an interface circuit to transmit the data island data and the compressed blanking period data via the multimedia communication link during one or more video blanking periods.
A receiving device for communicating via a multimedia communication link, the receiving device comprising:
- an interface circuit to receive data island data and compressed blanking period data via a multimedia communication link during one or more video blanking periods, the data island data including at least one of auxiliary data or audio data;
- and
- a decompression circuit to decompress the compressed blanking period data but not-decompress the data island data, the compressed blanking period data decompressed into blanking period data describing video blanking states.
A method for communicating via a multimedia communication link, the method comprising:
- receiving data island data that includes at least one of auxiliary data or audio data;
- receiving blanking period data describing video blanking states;
- compressing the blanking period data into compressed blanking period data but not compressing the data island data;
- and
- transmitting the data island data and the compressed blanking period data via the multimedia communication link during one or more video blanking periods.
A method for communicating via a multimedia communication link, the method comprising:
- receiving data island data and compressed blanking period data via a multimedia communication link during one or more video blanking periods, the data island data including at least one of auxiliary or audio data;
- and
- decompressing the compressed blanking period data into blanking period data but not decompressing the data island data, the compressed blanking period data decompressed into blanking period data describing video blanking states.
