Abstract
A method and system of partitioning and packetizing video data in an H.26L environment. An H.26L coding system is disclosed, comprising: a video coding layer (VCL) having a first partition mode and a second partition mode for partitioning video data, wherein the second partition mode separately partitions low and high frequency DCT coefficients; and a network adaptation layer (NAL) for packetizing data into a first and second packet, wherein the first packet is configured to contain all low frequency DCT coefficients and the second packet is configured to contain all high frequency DCT coefficients when the second partition mode is implemented by the VCL.
