On satellite, this would have meant as many individual feeds of BBC Two as BBC One whilst in the case of digital terrestrial, a decision to encode all BBC services other than BBC One using the more efficient statistical multiplexing technique made it technically and economically much harder to provide variations without either equipping each regional centre with costly equipment or using the same method as for BBC One and suffering reduced picture quality as a result.
Satellite broadcasting required separate channels for BBC Two and BBC One, while terrestrial broadcasting used a more efficient method of encoding multiple programs on one channel, making it harder to offer variations without costly equipment or sacrificing picture quality.
