ENCODER CONTROL APPARATUS AND METHOD

摘要

The present invention relates to an encoder control apparatus (16) which is configured to control a video encoder (14). The video encoder (14) is of a kind that is operable to encode a video coding unit in accordance with one of a plurality of encoding strategies, the plurality of encoding strategies imposing respectively different computational burdens . The encoder control apparatus comprises a controller (24) configured to generate a control output in dependence upon a target value, the target value corresponding to a computational burden to be placed on a signal processing component when processing the video coding unit. In use of the encoder control apparatus, the control output is provided to the encoder to select one of the plurality of encoding strategies, whereby the encoder encodes the video coding unit in accordance with the selected encoding strategy.
