I recently came across this device: USB Video Grabber, and it got me thinking.
What it does in a nutshell is to take the analogue signals from the composite cables (red, yellow, white) and smush that into a USB input, which presumably is interpreted by some software.
I have a digital TV set top box, a Soniq QMD501H, which I have connected to my pre-digital TV set. This basically takes the RF cable (from antenna) as an input, and outputs to composite cables (red, yellow, white), which I plug into my TV set. If I buy this device, instead of plugging it the component cables into the TV, I can plug them into this device, and plug this device into my computer, and watch/record TV on my computer.
However, what I realised was that this was a rather circuitous route: there's at least two conversions going on, at least one of which is completely unnecessary.
My set top box tells me that the Standard Definition channels are broadcast in
MPEG2, and the High Defintion channels are broadcast in
MPEG2 some format it simply calls
HD (720p and 1080i).
My computer can understand all of these formats, so I was wondering, why not get these to input directly into my computer?
Is there a device / software that will allow me to bypass the the digital set top box, and get the digital signal directly onto a computer?
If this is not possible, how can I achieve this through my digital set top box?
My digital set top box also has a
HDMI output, and a
Y-Pb-Pr outputs that are currently unused, in addition to the composite cables used by the TV..
My computer only has
USB inputs (it's a laptop).
