Foreword This South African standard was approved by National Committee SABS/TC 074/SC 03, Communication technology Broadcasting, in accordance with procedures of the SABS Standards Division, in compliance with annex 3 of the WTO/TBT agreement. This document was approved for publication in August 2015. This document was written for use in South Africa only. It therefore might not be suitable for direct application in other countries where conflicting conditions exist. Reference is made in 5.2 and 6.1 to "broadcasting service licensees". In South Africa, this means the free-to-air individual broadcasting service licensees or their appointed agents (trusted third parties). Contact details of these broadcasting service licensees are available from the Independent Communication Authority of South Africa (ICASA) at the following address: Independent Communication Authority of South Africa Blocks A, B, C and D, Pinmill Farm 164 Katherine Street Sandton 2146 Email: www.icasa.org.za Introduction Digital Terrestrial Television (DTT) broadcasting has been trialled in South Africa since 1 November 2008 using the Digital Video Broadcasting Terrestrial System (DVB-T). In January 2011 the Second Generation Digital Video Broadcasting Terrestrial System (DVB-T2) was confirmed as the transmission standard to be used in South Africa. Initially, the DTT service will be available in parallel with the existing analogue network. The objective of this standard is to provide requirements for Integrated Digital Television (IDTV) which will provide good quality video and sound to the viewer. Specific features not covered in this standard can be regarded as optional. For the South African DTT networks, cached MHEG Profile for South African applications and data will be used to avoid the high bandwidth needs of carousels. The MHEG-5 application environment, in accordance with ISO/IEC 13522-5, ETSI ES 202 184 and the MHEG-5 Profile for South Africa, have been selected for easy integration. The South African MHEG-5 profile supports a return path, which is optional in this document.

Integrated Digital Television (IDTV) for free-to-air digital terrestrial broadcasting 1 Scope This standard sets out the minimum technical requirements for standard-definition and highdefinition Integrated Digital Television (IDTV) for free-to-air terrestrial transmission in South Africa. NOTE 1 IDTV comprises a low-cost, low-maintenance unit that provides basic decoding of DTT broadcasts to provide UHF modulated outputs, and an Electronic Programme Guide (EPG) that provides details of the available services. NOTE 2 Although this standard applies to free-to-air integrated digital television, any other IDTV which is capable of receiving the free-to-air DTT services should ensure that the audio and video services and overthe-air applications are broadcast fully, without any alteration or hindrance. 2 Normative references The following referenced documents are indispensable for the application of this document.
