that the equipment functions perfectly, demonstrations may be arranged in particular in areas where DTTB is broadcast for the first time. 2. Roll out planning in accordance with ASO plan The milestones of the roll-out plan are given by the ASO plan. The roll-out plan should take account of the time periods needed for delivery of equipment, installation and testing of equipments, tests and demonstrations. 3. Coverage assessment at each stage of For each of the implementation (before implementation and after ASO) detailed coverage maps should be produced. These maps are needed for managing switch-over and as a basis for communication to viewers. Annex 5 Information on DTTB standards In this annex a summary is given of technical information on transmission standards obtained from ITU and other sources. 1 General The most important ITU-R Recommendations regarding DTTB standards are: Recommendation ITU-R BT.1306, Error correction, data framing, modulation and emission • methods for digital terrestrial television broadcasting. Recommendation ITU-R BT.1877, Error-correction, data framing, modulation and emission • methods for second generation of digital terrestrial television broadcasting systems. Recommendation ITU-R BT.1368, Planning criteria for digital terrestrial television services in the • VHF/UHF bands. Recommendations can be downloaded freely from the ITU website by using the indicated hyperlinks. For all other ITU documents mentioned in this annex ITU TIES login and password are required. Work is in progress on Recommendations ITU-R BT.1306 and ITU-R BT.1368. ITU-R Working Party 6A is carrying forward: a Preliminary Draft Revision to Recommendation ITU-R BT.1306 with new information on the • DTMB standard; a Preliminary Revision to Recommendation ITU-R BT.1368 with new information on the • DTMB and DVB-T2 standard. It is expected to progress this work at the next meeting of Working 6A in May 2011.
