Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard uses the translation method identical with IEC 61938:1996 "Audio, video and audiovisual systems - Interconnections and matching values \u200b\u200bof the analog signal Preferred matching values. " the editorial changes made the following standard.

a) with a decimal point instead of a comma as the decimal point, '' '';

b) Remove the preface to international standards.

This standard replaces GB/T 14197-1993 "preferred matching values \u200b\u200bfor the interconnection of sound system" and GB/T 9031-1988 "home sound system Equipment on interconnections and matching requirements. " this standard and GB/T 14197-1993 compared to the main changes are as follows.

a) In Chapter 3, before adding "Range" and "normative references";

b) the new Chapter 2 General conditions and definitions;

c) New 5.1.1 Cable characteristics;

d) to GB/T 14197-1993 Chapter 3 mark content to supplement, forming Chapter 6 signs and flags with the symbol;

e) of the GB/T 14197-1993 Chapter 9 general purpose input supplement, forming a Chapter 7 Electrical matching values;

f) New Table 2a) general purpose consumer audio device connected with the value of proprietary interfaces;

g) New Table 2b) general-purpose audio professional (non-broadcast-type) interface and audio and video signals have a common wire or cable consumption Mating value class device interface;

h) added 6.3 General purpose video input/output.
