Abstract
An asynchronous switching system and method for processing SDI data streams, the system and method utilizing one or more buffers for cleaning up an output of a dirty IP switch.
Claims20
An apparatus for switching video signals and cleaning up a resulting video output comprising:
- first and second buffers;
- first and second video frame sources;
- capacity provided to a cleaner by the first buffer accommodates less than three video frames;
- capacity provided to the cleaner by the second buffer accommodates less than two video frames;
- a first frame package sent from the first video frame source provides a frame package received by the first buffer;
- the first buffer plays out the first frame package and loops back to replay out a portion of the frame package again;
- after the first frame package is sent, a second frame package is sent from the second video frame source and provides a frame package received by the second buffer;
- and,
- detection of a start-of-frame in the second buffer results in play from the second buffer.
6 more elements
A method for switching video signals and cleaning up a resulting video output comprising the steps of:
- a first video frame source sending a first frame package to load a first buffer;
- the first buffer playing out the first frame package and looping back to replay out a portion of the frame package again;
- and,
- after the first frame package is sent, a second video frame source sending a second frame package to load a second buffer;
- wherein detection of a start-of-frame in the second buffer results in transition from first buffer playback to second buffer playback at the start of the frame in the second buffer.
