A method for decoding a video bitstream comprising: (a) receiving a base bitstream representative of a coded video sequence; (b) receiving a plurality of enhancement bitstreams that includes a plurality of enhancement layers representative of said coded video sequence; (c) receiving a video parameter set extension containing syntax elements that apply to said base bitstream and said plurality of enhancement bitstreams, wherein said syntax elements include decoded picture buffer related parameters for a decoded picture buffer for at least one of said enhancement bitstreams, wherein said decoded picture buffer related parameters are derived based upon said syntax elements for an operation point, wherein said syntax elements for said operation point include: vps_max_num_reorder_pics, vps_max_latency_increase_plus1, and vps_max_dec_pic_buffering_minus1; wherein said syntax elements are signaled for a sub-group of said base bitstream and said plurality of enhancement layers, wherein said sub-group corresponds to an output layer set and said operation point; (d) decoding said output layer set, wherein said decoded picture buffer related parameters are used for the output and removal of pictures from said decoded picture buffer, wherein said output and removal of pictures from the decoded picture buffer is determined based on said decoded picture buffer related parameters for said output layer set. (a) receiving a base bitstream representative of a coded video sequence; (b) receiving a plurality of enhancement bitstreams that includes a plurality of enhancement layers representative of said coded video sequence; (c) receiving a video parameter set extension containing syntax elements that apply to said base bitstream and said plurality of enhancement bitstreams, wherein said syntax elements include decoded picture buffer related parameters for a decoded picture buffer for at least one of said enhancement bitstreams, wherein said decoded picture buffer related parameters are derived based upon said syntax elements for an operation point, wherein said syntax elements for said operation point include: vps_max_num_reorder_pics, vps_max_latency_increase_plus1, and vps_max_dec_pic_buffering_minus1; wherein said syntax elements are signaled for a sub-group of said base bitstream and said plurality of enhancement layers, wherein said sub-group corresponds to an output layer set and said operation point; wherein said syntax elements include decoded picture buffer related parameters for a decoded picture buffer for at least one of said enhancement bitstreams, wherein said decoded picture buffer related parameters are derived based upon said syntax elements for an operation point, wherein said syntax elements for said operation point include: vps_max_num_reorder_pics, vps_max_latency_increase_plus1, and vps_max_dec_pic_buffering_minus1; vps_max_num_reorder_pics, vps_max_latency_increase_plus1, and vps_max_dec_pic_buffering_minus1; wherein said syntax elements are signaled for a sub-group of said base bitstream and said plurality of enhancement layers, wherein said sub-group corresponds to an output layer set and said operation point; (d) decoding said output layer set, wherein said decoded picture buffer related parameters are used for the output and removal of pictures from said decoded picture buffer,
