<p>The invention relates to apparatus, system and a method to allow the generation of radio and/or television channels and, upon the user selection to change channel, the delay in the generation of the new channel to be minimised, especially when the new channel requires access authorisation and/or data decrypting and/or descrambling to be performed The data for the new channel is obtained and placed into a memory means in sequence until access authorisation is achieved at which point the data is then retrieved in sequence from the memory rather than the live datastream.
