The invention relates to a system and a method for the transmission of digital data which is representative of video and audio content of the type which can be used for television programming. The invention allows the decision of when to end and start groups of data for the video and/or audio to be made with reference to the actual video and/or audio content and in particular to be made with reference to a detected or detectable change in the video or audio content such that the end of one group and start of the next group of data can be synchronised to occur at the same time as, or at a time determined with respect to, said change. The invention also discloses the storing of the groups of data as self contained items or records and the storage of the same in one or more databases from which the groups can be selected and transmitted for the generation of video and/or audio content. |
