Abstract
In the recording of broadcast television text, the text is separated from the video signal and formed into blocks at slicer and then is fed into shift register. It is then taken out at a data rate lower than that when broadcast and coding is assigned to at least some of the blocks prior to recording onto a video cassette tape recorder. Retrieval and display incorporate similar functions in reverse order. In another embodiment data in block form is stored on a video disk for similar retrieval and display.
