Abstract
A method and apparatus is provided for providing local screen data of a source device, such as a personal computer, to a sink device, such as a television, game console, or home theatre system, at a rate determined by the sink device. In one example, the method and apparatus responds to requests from the sink device to provide local screen data by serving the local screen data to the sink device from a circular buffer. The local screen data is written to the circular buffer in FIFO order based on the requests from the sink device, and read from the circular buffer based on the requests.
Claims28
A method of providing local screen data to a sink device, comprising:
- responding to requests from the sink device to provide local screen data at a rate determined by the sink device by serving the local screen data to the sink device from a circular buffer.
A computer-readable storage medium storing instructions that, when executed by a processor in a source device, cause the processor to:
- respond to requests from a sink device to provide local screen data at a rate determined by the sink device by serving the local screen data to the sink device from a circular buffer.
An apparatus for providing local screen data to a sink device, comprising:
- a local screen data control system including
- a circular buffer, and
- a controller operative to respond to requests from the sink device to provide local screen data at a rate determined by the sink device by making the local screen data available to the sink device from a circular buffer.
