摘要： An encoder for use in scalable video coding has a mechanism to perform macroblock mode selection for the enhancement layer pictures. The mechanism includes a distortion estimator for each macroblock that reacts to channel errors such as packet losses or errors in video segments affected by error propagation; a Lagrange multiple selector for selecting a weighting factor according to estimated or signaled channel error rate, and a mode decision module or algorithm to choose the optimal mode based on encoding parameters. The mode decision module is configured to select the coding mode based on a sum of the estimated coding distortion and the estimated coding rate multiplied by the weighting factor.

摘要： A video coding mechanism is disclosed. The mechanism includes receiving a bitstream comprising an output layer set (OLS) and a video parameter set (VPS). The OLS includes one or more layers of coded pictures and the VPS includes an OLS mode identification code (ols_mode_idc) specifying that for each OLS, all layers in the each OLS are output layers. The output layers are determined based on the ols_mode_idc in the VPS. A coded picture from the output layers is decoded to produce a decoded picture. The decoded picture is forwarded for display as part of a decoded video sequence.

摘要： A method of video decoding comprises receiving a bitstream including a SPS, a PPS, and subpictures associated with a subpicture ID mapping. A determination is made of whether an SPS flag has a first or second value. The SPS flag having the first value specifies that the subpicture ID mapping is signaled in the SPS, and the second value specifies that the subpicture ID mapping is signaled in the PPS. The subpicture ID mapping is obtained from the SPS when the SPS flag has the first value and from the PPS when the SPS flag has the second value or the PPS flag has the first value.

摘要： A video coding mechanism is disclosed. The mechanism includes encoding a coded layer video sequence (CLVS) for a layer in a bitstream. A sequence parameter set (SPS) referred to by the CLVS is also encoded into the bitstream. The SPS is constrained to have a network abstraction layer (NAL) unit header layer identifier (nuh_layer_id) value equal to a nuh_layer_id value of the CLVS when the layer does not use inter-layer prediction. The bitstream is stored for communication toward a decoder.
