Just as with present analog broadcasting and digital BS broadcasting, digital terrestrial broadcasting follow a precise program schedule that includes national broadcasts from its headquarters and local broadcasts from its regional broadcasting stations. In addition to high-quality picture and sound Hi-Vision (HDTV) broadcasting, digital terrestrial broadcasting will offer viewers a wide range of new services made feasible by the digital format. These include "multi-view broadcasting," which transmits multiple programs simultaneously, data broadcasting, and the electronic program guide (EPG). To facilitate such new services, the necessary upgrades and improvements are being made on transmission systems in broadcasting stations nationwide. |

Transmission Systems |
| |
To transmit a variety of services to the 53 regional broadcasting stations located throughout the country, we developed a transmission system that is capable of multiplexing video, audio, EPG, data broadcasting, and other data on a channel equivalent to that used for a single TV circuit. The construction of a countrywide network system is underway, and much effort is also being put into budget reduction by means of reducing the equipment's energy consumption and space, and by controlling the circuit leasing fee.
NHK will upgrade broadcasting stations with digital terrestrial broadcasting transmission systems to keep pace with the technical progress in digital terrestrial broadcasting.
