When a transmission network for digital terrestrial television broadcasting (DTTB) is being deployed@ new networking technologies such as the Single Frequency Network (SFN) can be employed excelling the conventional analogue TV systems. However@ new technical evaluation parameters are introduced for installing SFN systems. In addition new quality evaluation methods are also established in order to achieve stable and high-quality broadcasting services avoiding the cliff effect@ which is one of the typical phenomena in the digital transmission that the signal quality is abruptly degraded when the received C/N becomes just lower than a specific value representing the system limit. Given the background described above@ this International Standard has the purposes of ? establishing measuring methods that enable the objective evaluation of the performance of transmission networks so as to make stable DTTB services a reality@ ? establishing a technical baseline@ such as a definition of technical terms@ to standardize measuring methods. The measurement methods described in this standard are intended for digital terrestrial television transmission network test and validation. The measurement methods for digital terrestrial transmitter are not included in this standard. These methods are described in IEC 62273-1. This standard does not give any regulations and/or mandatory requirements. The specifications and requirements defined for each system have priority over this standard. However@ there may be some cases where details are not specified in each individual specification or different systems should be evaluated under a common measurement method. The purpose of this standard is to provide a common technical baseline that makes measurement results comparable in all cases.
