Abstract:
1. A method of selectively decoding an input stream, said method comprising: receiving an encoded input stream for display as a plurality of frames in a display window; determining, while receiving the encoded input stream, that an overlay is to be displayed over the plurality of frames; determining a location of the overlay on the plurality of frames; determining if the overlay is one of (i) an opaque overlay and (ii) a translucent overlay; selectively decoding the encoded input stream to selectively generate the plurality of frames based at least upon the location of the overlay on the plurality of frames, wherein selectively decoding includes generating partial versions of the plurality of frames if the overlay is the opaque overlay, and generating full versions of the plurality of frames if the overlay is the translucent overlay; and displaying the generated plurality of frames and the overlay.
