Anotácia textu normy ČSN ETSI EN 302755-V1.4.1 (879047):
V1.4.1 The present document describes a second generation baseline transmission system for digital terrestrial television broadcasting. It specifies the channel coding/modulation system intended for digital television services and generic data streams. The scope is as follows: - it gives a general description of the Baseline System for digital terrestrial TV; - it specifies the digitally modulated signal in order to allow compatibility between pieces of equipment developed by different manufacturers. This is achieved by describing in detail the signal processing at the modulator side, while the processing at the receiver side is left open to different implementation solutions. However, it is necessary in this text to refer to certain aspects of reception. Versions 1.1.1 and 1.2.1 of the present document [i.7] and [i.8] defined a single profile which incorporates time-slicing but not time-frequency-slicing (TFS). Features which would allow a possible future implementation of TFS (for receivers with two tuners/front-ends) can be found in annex E. It is not intended that a receiver with a single tuner should support TFS. Version 1.3.1 of the present document [i.9] added a T2-Lite profile. This profile is intended to allow simpler receiver implementations for very low capacity applications such as mobile broadcasting, although it may also be received by conventional stationary receivers. The details of this T2-Lite profile are described in annex I. Version 1.3.1 of the present document [i.9] also introduces a name, which is ´T2-base profile´, for the previous single profile. Version 1.4.1 (the present document) made a number of changes, but all of these are clarifications of particular points, changes in non-normative recommendations, and corrections to the wording; no new technical features have been added and no changes have been made to existing features
