Hardware and Operating Considerations of The Decoder Interface (1997)
By Joseph B. Glaab, General Instrument
The hardware specification of the Decoder Interface is finished. The control software is almost finished. Products incorporating the Decoder Interface will soon appear on the market. This paper describes the details of what will be in the TV, VCR, and decoder, and how these units will interact to create a consumer friendly system which permits watching one program while recording another, recording successive programs on different channels, and doing this whether the channels are in the clear or scrambled. In addition, none of the features of the TV, such as picture in picture (PIP), are kept from working as originally intended.
