HEVC NAL Unit Headers and RTP Fragmentation Units in RTP Streaming
HEVC NAL unit header (2 bytes) HEVC encodes each NAL unit with a 16‑bit header laid out as: forbidden_zero_bit: 1 bit (must be 0) nal_unit_type: 6 bits nuh_layer_id: 6 bits nuh_temporal_id_plus1: 3 bits Bit packing across the two bytes (b7 is MSB): byte0: b7=fzb, b6..b1=type, b0=layer_id[5] byte1: b...
