Method and apparatus for video recording

Claim 1

A control system for connecting a cable television system to a video cassette recorder and a television receiver comprising: input means for receiving a plurality of very high frequency television signals transmitted by said cable television system; means for directing said transmitted signals through first and second conduits defining respectively first and second signal flow paths; a multi-channel converter provided in said first flow path including selector means for selecting a single very high frequency signal from the plurality of very high frequency signals transmitted by said cable television system and for converting said single signal to a preselected converter very high frequency output signal; trap means including an output provided in said second flow path for eliminating said preselected converter output signal from the very high frequency signals transmitted by said cable television system; means connected to said first and second conduits for combining said preselected converter output signal and the very high frequency signals transmitted from the output of said trap means; a video cassette recorder connected to an output of said combining means for receiving said combined signals whereat any very high frequency signal comprised within the cable television system transmitted signals may be recorded; and a television receiver connected to the output of said combining means for receiving said combined signal whereat any signal comprised within the cable television system transmitted signals may be viewed.

Claim 4

A system in accordance with claims 1 or 2 further including trap means for receiving said preselected converter output signal for removing any additional very high frequency signals carried with said selected converter output signal.

Claim 5

A method of operating a video cassette recorder and television receiver on a cable television system comprising the steps of: receiving the very high frequency signals transmitted by the cable television system; directing the very high frequency signals through first and second flow paths; selecting a single very high frequency signal from the total signals directed through the first flow path; converting the selected signal to a preselected very high frequency output signal; eliminating the preselected very high frequency output signal from the cable system signals directed through the second flow path; combining the preselected very high frequency output signal with the remaining signals passing through the second flow path; directing the combined signals to a video cassette recorder whereat any channel comprised within the signals transmitted by the cable television system may be recorded; and further directing the combined signals to a television receiver whereat any channel comprised within the signals transmitted by the cable television system may be viewed.

Claim 6

A method of operating a video cassette recorder and television receiver on a cable television system comprising the steps of: receiving the very high frequency signals transmitted by the cable television system; directing the very high frequency signals through first and second flow paths; selecting a single very high frequency signal from the total signals directed through the first flow path; converting the selected signal to a preselected very high frequency output signal; eliminating the preselected very high frequency output signal from the cable system signals directed through the second flow path; combining the preselected very high frequency output signal with the remaining signals passing through the second flow path; directing the combined signals to a video cassette recorder whereat any channel comprised within the signals transmitted by the cable television system may be recorded; and further directing the combined signals to a television receiver whereat any channel comprised within the signals transmitted by the cable television system may be viewed.
