For retransmission of 8K satellite broadcasting via cable TV networks
・Each 8K signal is divided up and sent through multiple channels (64QAM*1 or 256QAM) of the cable TV transmission system. In this way, it can be delivered to subscribers without any changes to the existing cable TV transmission paths.
・This system supports the MMT*2 and TLV*3 multiplexing schemes that will be used for 8K test broadcasting in 2016.
*1 QAM (Quadrature Amplitude Modulation): A digital modulation scheme that conveys information on the amplitude and phase of a carrier.
*2 MMT (MPEG Media Transport): International standard media transport scheme supporting various transmission paths.
*3 TLV (Type Length Value): A transmission signal format to efficiently transmit IP packets (variable-length packets) over broadcasting channels
