The 4K/8K BS trial broadcasting will start from August 2016. The BS has so wide bandwidth that it can transmit 4K HEVC with 44Mbps. A cable network restricts the bandwidth to 29Mbps/38Mbps by the 64/256QAM specification. In this manuscript, a BS 4K transcoding performance is reported for the feasibility study of a retransmission over the cable network.
