Cable TV Transmission System for 8K Broadcasting

For retransmission of 8K satellite broadcasting via cable TV networks

Outline

This exhibit shows a cable TV retransmission system for the 8K test broadcasts starting in 2016. The system enables 8K signals with 16 times the volume of information of Hi-Vision to be distributed through multiple channels of existing cable TV networks.

Features

・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
