Recording and re-insertion of teletext data

摘要

A digital recording system comprising a digital processor and a memory. The digital processor selects related data packages from a datastream, wherein said related data packages are interleaved with other data packages in the datastream in a repeating cycle. The digital processor stores the selected related data packages in a file in a memory. The same or another processor may creates a playback datastream of the recorded related data packages by retrieving the initially recorded data packages for the recorded related data packages for output in the playback datastream. The processor retrieves and substitutes subsequently recorded related data packages in the playback datastream at the appropriate point to create the playback datastream.
