  • Publication number: 20190253726
    Abstract: The buffer management methods simplify the complexity of STD buffer management for HEVC and make is easy to implement HEVC in deployed AVC/MPEG-2 networks (as legacy re-multiplexers are able to be used for re-purposing HEVC content). The buffers for base and enhancement layers are also also be managed independently before re-assembly and this simplifies the STD model. Re-assembly is still implemented before decoding an enhanced HEVC video stream.
