Abstract
The invention relates to a multiplexed video digitization system and method. The system includes a plurality of analog video signals, a multiplexer to select one of the plurality of analog video signals, and an analog-to-digital converter to convert the selected analog video signal into a digital video signal. The plurality of analog video signals may include component video signals, red, green, and blue signals, or s-video signals. The multiplexer may include control logic to select the one of the plurality of analog video signals. The system may include a plurality of sample and hold circuits to insure time aligned sampling of the corresponding plurality of video signals.
Claims29
A system comprising:
- a plurality of analog video signals;
- a multiplexer to select one of the plurality of analog video signals as an output signal;
- an analog-to-digital converter to convert the output signal into a digitized signal;
- control logic to cycle a selection of the multiplexer to each of the plurality of analog video signals within a time period related to a bandwidth of one of the analog video signals.
A system comprising:
- means for receiving a plurality of analog video signals;
- means for selecting one of the plurality of analog video signals as an output signal;
- means for converting the output signal to a digitized signal;
- and
- means for cycling a selection of the means for selecting to each of the plurality of analog video signals within a time period related to a bandwidth of one of the analog video signals.
A method comprising:
- receiving a plurality of analog video signals;
- selecting one of the plurality of analog video signals as an output signal;
- and
- converting the output signal into a digitized signal;
- and
- cycling the selection of the one the plurality of analog video signals to each of the plurality of analog video signals within a time period related to a bandwidth of one of the analog video signals.
A system comprising:
- a plurality of analog video signals;
- a multiplexer to select one of the plurality of analog video signals;
- and
- an analog-to-digital converter to convert the selected analog video signal into a digital video signal;
- where the analog-to-digital converter includes a sample rate proportional to a desired sample rate times a number of analog video signals.
A system comprising:
- means for receiving a plurality of analog video signals;
- means for selecting one of the plurality of analog video signals;
- and
- means for converting the selected analog video signal to a digital video signal;
- where the means for converting includes a sample rate proportional to a desired sample rate times a number of analog video signals.
A method comprising:
- receiving a plurality of analog video signals;
- selecting one of the plurality of analog video signals;
- and
- converting the selected analog video signal into a digital video signal;
- where converting the selected analog video signal includes converting the selected analog video signal at a sample rate proportional to a desired sample rate times a number of analog video signals.
