Project

Reference HD 544 S1:1989
Title Audio recording - PCM encoder/decoder system
Project Number 4001
Abstract/Scope Applies to the reversible process achieved by the PCM encoder/decoder system that transforms two audio signals into one PCM signal for compatibility, with either 525 line/ 60 field or 625 line/50 field television system. Establishes the signal format for the PCM encoder decoder for reproducing audio signals in PCM form on a consumer video cassette system. Ensures standardized system operation compatibility of encoder/decoder systems and interchangeability of recorder tapes with players and systems.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved


(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat


(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level


(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement


(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
