摘要
說明書
In an embodiment, one of the first multiplexed image frame or the second multiplexed image frame is outputted in a base layer bitstream in a plurality of bit streams, while the other of the first multiplexed image frame or the second multiplexed image frame is outputted in an enhancement layer bitstream in the plurality of bit streams.
In an embodiment, the multi-layer video encoder (100) is further configured to perform: generating, based at least in part on the first multiplexed image frame, prediction reference image data; and encoding an enhancement layer video signal based on differences between the prediction reference image data and the second input image frame.
In an embodiment, the multi-layer video encoder (100) is further configured to perform: applying one or more first operations comprising at least one of (a) spatial frequency filtering operations or (b) spatial subsampling operations in the second direction to the first input image frame and the second input image frame in generating the first multiplexed image frame, wherein the one or more first operations removes high spatial frequency content in the second direction and preserves high spatial frequency content in the first direction; and applying one or more second operations comprising at least one of (a) spatial frequency filtering operations or (b) spatial subsampling operations in the first direction to the first input image frame and the second input image frame in generating the second multiplexed image frame, wherein the one or more second operations removes high spatial frequency content in the first direction and preserves high spatial frequency content in the first direction.
