Abstract: A device and method for playing digital video are disclosed. The device includes multiple graphics processing units. The method involves using the multiple graphics processors to decode and output compressed audiovisual stream to a display and a speaker. Audiovisual bit streams possibly containing multi-stream video are efficiently decoded and displayed by sharing decoding-related tasks among multiple graphical processing units.
