1 Scope
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 International Standard applies
only to completely functional stationary (or semi -stationary) digital TV receivers such as set top boxes, integrated digita l TVs, recorders and other products whose
primary function is to receive TV content. Where this standard refers to TV, this
will be shorthand for all such receivers .
This International Standard 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).
