Digital terrestrial television receivers for the DTMB system (IEC 62753:2015); German version EN 62753:2015

IEC 62731:2018 电视用文本语音转换.通用要求

This International Standard specifies the text-to-speech functionality for a (broadcast) receiver with a text-to-speech system. Such a system may be one device, i.e. a receiver with an integrated text-to-speech generator, or may be two devices, i.e. a receiver interfacing with an external text-to-speech device. This document applies only to completely functional stationary (or semi-stationary) digital TV receivers such as set top boxes, integrated digital TVs, recorders and other products whose primary function is to receive TV content. Where this document refers to TV, this will be shorthand for all such receivers. This document does not apply to products that are capable of receiving TV as a secondary function (e. g. PCs or game consoles with digital television receivers). It also does not apply to sub-assemblies (e. g. PC tuner cards).
