|Operational Guideline Composite Digital Video Interface in the NTSC/M Television System Overview of Technical Report (ARIB TR-B5)
This technical report specifies the operational guideline for the allowable range of data deviation that enables synchronization separation to be performed reliably at the parallel interface or serial interface of the composite digital video signal in an NTSCM/M television system, using the synchronization-signal data on that interface.
The contents of the stipulation conform to RS-170A of the EIA standard, which is a commonly used antecedent of the synchronization-signal standard SMPTE-170M provided for analog signals, and specify operational guidelines whereby the synchronization-data deviation is controlled so as not to deviate from a range that meets the RS-170A standard.
This technical report shall apply to all video equipment for broadcast, each having a composite digital input/output of the NTSC/M television system.
This technical report is composed of a main section of four chapters, explanations, related standards, references, and addendum.
Chapter 1: Object
Chapter 2: Scope
Chapter 3: Definition of Terms
Chapter 4: Operational guidelines
4.1 Synchronization output standard for the composite parallel signal
4.2 Synchronization input standard for the composite parallel signal
4.3 Synchronization output standard for the composite serial signal
1. Purpose of enactment
2. Explanation of main points
3. Synchronization standard for the composite parallel signal
4. Synchronization standard for the composite serial signal
5. Conversion of digital data of the RS-170A standard
Chapter 1 describes the object of the enactment of this technical report. Details are given in Explanation 1.
Chapter 2 explains that this technical report is the standard with a scope covering the composite digital signal of the NTSC/M-system video signal.
Chapter 3 explains the definitions of the terms used in the body and the explanations.
Chapter 4 specifies the operational guideline for the composite digital signal of the NTSC/M system video signal. Supplementary explanations are given in Explanations 3 to 5.
The references specify the synchronization value recommended by SMPTE 244M and explain the calculations of the data value for the synchronization slope. Further, a diagram showing the allowable range for synchronization data is presented.
The addendum is a copy of the Broadcasting Technology Standard (BTS) given in the body, which is appended to enable the reader to refer thereto in the future, as the BTS was abolished by the end of July 2001.
