ISDB-T와 ISDB-Tsb property

ISDB-T/ISDB-Tsb API 확장은 어떤 ISDB-T/Tsb 하드웨어도 tuning하는 데 필요한 정보를 모두 반영하는 것을 목표로 합니다. 일부 고급 장치는 특정 매개변수 없이도 tuning할 수 있습니다.

이 설명은 응용 프로그램 작성자가 Linux Digital TV API로 ISDB-T와 ISDB-Tsb 하드웨어를 다루는 데 필요한 기본 의존 관계를 제공합니다. 더 자세한 정보는 ARIB STD-B31과 ARIB TR-B14를 참조해야 합니다.

ISDB 전용 매개변수를 이해하려면 한 ISDB-T 채널이 13개 segment로 구성되고, 최대 3개 layer가 그 segment를 공유할 수 있다는 채널 구조 지식이 필요합니다.

DTV QoS 통계도 유효합니다.

.. _isdbt:

ISDB-T delivery system
======================

This ISDB-T/ISDB-Tsb API extension should reflect all information needed
to tune any ISDB-T/ISDB-Tsb hardware. Of course it is possible that some
very sophisticated devices won't need certain parameters to tune.

The information given here should help application writers to know how
to handle ISDB-T and ISDB-Tsb hardware using the Linux Digital TV API.

The details given here about ISDB-T and ISDB-Tsb are just enough to
basically show the dependencies between the needed parameter values, but
surely some information is left out. For more detailed information see
the following documents:

ARIB STD-B31 - "Transmission System for Digital Terrestrial Television
Broadcasting" and

ARIB TR-B14 - "Operational Guidelines for Digital Terrestrial Television
Broadcasting".

In order to understand the ISDB specific parameters, one has to have
some knowledge the channel structure in ISDB-T and ISDB-Tsb. I.e. it has
to be known to the reader that an ISDB-T channel consists of 13
segments, that it can have up to 3 layer sharing those segments, and
things like that.
