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.
Claims14
A transmitting device for communicating via a multimedia communication link, the transmitting device comprising:
- compression circuitry to receive blanking period data corresponding to blanking states of video blanking periods, the compression circuitry compressing the blanking period data into compressed blanking period data, wherein for at least a video blanking period of the video blanking periods that comprises one or more data islands, the compression circuitry compresses the blanking period data for the video blanking period by dividing the blanking period data for the video blanking period into different portions that are separated by the one or more data islands and separately compressing each of the different portions with run length coding;
- and
- an interface to transmit signals corresponding to the compressed blanking period data via one or more multimedia channels of the multimedia communication link.
A receiving device for communicating via a multimedia communication link, the receiving device comprising:
- an interface to receive, via one or more multimedia channels of the multimedia communication link, signals corresponding to compressed blanking period data;
- and
- decompression circuitry to decompress the compressed blanking period data into blanking period data corresponding to blanking states of video blanking periods,
- wherein, for a least a video blanking period of the video blanking periods, the compressed blanking period data for the video blanking period includes different portions that are separated by one or more data islands, and the decompression circuitry decompresses the different portions into the blanking period data with run length decoding.
A method comprising:
- receiving blanking period data corresponding to blanking states of video blanking periods;
- compressing the blanking period data into compressed blanking period data, wherein for at least a video blanking period of the video blanking periods that comprises one or more data islands, the blanking period data for the video blanking period is compressed by dividing the blanking period data for the video blanking period into different portions that are separated by the one or more data islands and separately compressing each of the different portions with run length coding;
- and
- transmitting signals corresponding to the compressed blanking period data via one or more multimedia channels of a multimedia communication link.
A method comprising:
- receiving, via one or more multimedia channels of a multimedia communication link, signals corresponding to compressed blanking period data;
- and
- decompressing the compressed blanking period data into blanking period data corresponding to blanking states of video blanking periods,
- wherein, for a least a video blanking period of the video blanking periods, the compressed blanking period data for the video blanking period includes different portions that are separated by one or more data islands, and the compressed blanking period data for the video blanking period is decompressed by decompressing the different portions into the blanking period data with run length decoding.
