The present document focuses on Gigabit Home Networking for Very High Speed Internet video distribution using video transcoding for the distribution of HD and UHD video streams over SISO and MIMO PLT networks [i.1]. The present document defines the transcoding of HD and UHD video for improvement of the house coverage of powerline networks for existing or forthcoming new video services as streaming and VOD MIMO-PLT and filling the gap between MIMO-PLT channels capacity and new services as UHD and HD video for forthcoming UHDTV, namely transcoding of H264/AVC into HEVC/H265. The SISO/MIMO Powerline networks channels have time varying capacities depending on noises, overage, range as HD and UHD encoded in H264/AVC video streams have additional bit rate compared to stream [3], [4] encoded in HEVC/H265, the usage of transcoding for video streaming over Powerline using SISO & MIMO PLT modems is explored by testing. The present document includes the technical specification for video transcoding and transportation standards impact on Powerline Networks coverage and produce technical guidance to the Powerline telecommunication vendors to cope with very high rate services over Powerline communication for the UHD and HD video transcoding coding.
