Abstract
An image pipeline (60) provides image data to a capture unit (61). The capture unit (61) generates a frame from the image data for compression by a compression unit (64). A frame spoiler (62) determines whether the frame is to be discarded prior to compression by the compression unit (64). An output buffer (66) to a network link provides an output indication to the frame spoiler (62) indicating that the output buffer (66) is congested. The frame spoiler (62) discards the frame in accordance with the output indication. Similarly, an input buffer (63) to the compression unit (64) provides an input indication to the frame spoiler (62) indicating that the input buffer (63) is congested. The frame spoiler (62) may discard the frame in accordance with the input indication or in accordance with a combination of the input indication and the output indication.
