Claim Text:
1. A method of generating a video sequence which includes a plurality of layers, comprising: providing a plurality of frames in the video sequence, each frame comprising a frame header; setting a deblocking control flag in a frame header of a selected frame to a selected one of a plurality of states to indicate that a deblocking parameter is presented for at least one and less than all of the plurality of layers of the selected frame; determining a content characteristic of the selected frame; comparing the content characteristic to first and second thresholds; if the content characteristic is less than the first threshold, setting a deblocking control flag in a frame header of a next frame to a selected state to indicate that a deblocking parameter is presented for each of the plurality of layers of the next frame; if the content characteristic is not less than the first threshold and is less than the second threshold, setting the deblocking control flag in the frame header of the next frame to a selected state to indicate that a deblocking parameter is presented for at least one and less than all of the plurality of layers of the next frame; and if the content characteristic is not less than the second threshold, setting the deblocking control flag in the frame header of the next frame to a selected state to indicate that a deblocking parameter is not presented for any of the plurality of layers of the next frame.
