A method for data transmission, comprising the steps of:
- receiving a multimedia stream through an electronic medium, the stream comprising a plurality of vectors;
- and
- based on the vectors, adding a plurality of error protection units to the multimedia stream.
A method for data transmission, comprising the steps of:
- receiving a video stream through an electronic medium, the stream comprising a plurality of vectors;
- assigning an importance to the vectors;
- based on the importance, partitioning the video stream;
- and
- based on the importance, adding a plurality of error protection units to the video stream.
A method for data transmission, comprising the steps of:
- generating a video transmission;
- converting the video transmission to a video stream, the video stream comprising a plurality of vectors;
- based on the importance, partitioning the video stream;
- and
- based on the importance, adding a plurality of error protection units to the video stream.
A system comprising:
- a motion-vector extractor for extracting one or more motion vectors from a video stream;
- a video stream partitioner for partitioning the video stream;
- an error-protection controller for adding error protection to the video stream;
- an analysis software tool for assigning an importance to each of the motion vectors, controlling the error-protection controller to add error protection based on the assigned importance, and controlling the video stream partitioner for partitioning the video stream based on the assigned importance;
- and
- a transmitter for sending the video stream to a device.
A computer-readable medium, having stored thereon, computer executable process steps operative to control a computer to document source files, the steps comprising:
- receiving a multimedia stream through an electronic medium, the stream comprising a plurality of vectors;
- and
- based on the vectors, adding a plurality of error protection units to the multimedia stream.
