Abstract
A system for communicating video data in a digital media device includes an application layer having one or more applications and further includes a device driver layer associated with an operating system and video hardware of the digital media device. A video abstraction layer (VAL) coupled to the application layer and to the device driver layer includes a send queue containing ordered references to buffers that are each capable of containing video data. The VAL also includes a receive queue containing ordered references to buffers each capable of containing video data. The send queue and receive queue are used in substantially the same manner for both incoming video data received into the digital media device and outgoing video data to be communicated from the digital media device.
