List of Standards for Broadcasting(in Japanese)

Receiver for Digital Broadcasting
Standard (ARIB STD-B21) Overview

This standard concerns specifications of receivers for digital broadcasting, and specifies, in particular, minimum basic functions and ratings and desired performance to satisfy initial needs for the deployment of digital satellite television broadcasting and other forms of digital broadcasting.

1. Scope (Ver. 3.0)

This standard applies to receivers for three types of digital broadcasting. The first is 11.7-12.2 GHz digital satellite television broadcasting for standard television broadcasting, high-definition television broadcasting, VHF broadcasting, and data broadcasting. The second is 12.2-12.75 GHz digital communication satellite television broadcasting, for 34.5-MHz-bandwidth standard television broadcasting, high-definition television broadcasting, VHF broadcasting, and data broadcasting. The third is digital broadcasting for standard television broadcasting and high-definition television broadcasting as performed by broadcast studios, or digital terrestrial television broadcasting.

While various types of receivers can be considered depending on the reception format, this standard concerns specifications for those standard receivers that use fixed antennas among receivers for digital satellite broadcasting, receivers for dual use of digital satellite broadcast and digital communication satellite broadcasting, and receivers for digital terrestrial broadcasting.

Compact and simple receivers, vehicle-mounted receivers, portable receivers, etc. will either apply or reference this standard.
