2 Digital broadcasting requirements of existing and already planned services In Cambodia, the geographical coverage of the TV services is not equal. Some TV services have only coverage in Phnom Penh and surroundings, others a considerable part of the country. In to estimate the spectrum requirements a number of simplifications and assumptions have to be made. The table below gives an overview of the existing and planned TV services as in Table 2.1 in section 2, with a simplified geographical coverage assumption.

Far away from Phnom Penh the spectrum requirement reduces to minimal seven channels (areas around sites that provide the 70 per cent coverage assumption plus the channel for T-DMB). It should be noted that in case of model A, the multiplex has a capacity of about 6 Mbit/s and contains one or two services. In case of one service, the multiplex is loaded for less than 50 per cent. In these cases an additional service can be transmitted without increasing the spectrum requirement.
