Hello, I have a question, it's time to switch from old good cable TV to digital TV. I have at home 1 TV (parents) and in my room a computer with a TV card. Unfortunately, the image on the monitor is tragic, because the cable gives too low resolution. On days, we change cable TV to digital in the estate. The cable will go to the TV straight from the set-top box (I skip multiroom aspects, because I don't know how at my estate solve this problem). However, what if I wanted to connect the decoder to the computer to continue watching TV on the computer as it is now? I warn you that I am not interested in direct connections to the monitor, because I use the computer many times and watch TV in the window next to it, or play a music station. To capture an image in HD, I have to use HDMI, right? So what to buy so that this image on the computer was in this HD, and not like with the help of SCART, or is there any decoder that will release after Composite 1080p? Can it be done in a small budget or are there only AVerTV Capture HD cards for over PLN 400?
PS: my current card is Winfast tv2000 xp expert, but I expect it is already a turn and it will not be suitable for a digital camera
EDIT 2: television works with the help of a CI card, so is there any cheap solution to this, in addition to (again) cards for over PLN 300?
EDIT 3: One thing is giving me peace all the time. On the plot I have the cheapest USB DVB-T tuner and plug in the old antenna to collect free channels. It catches me all and I think it is HD quality because on a 1366x768 laptop resolution everything looks nice and without pixels. Or is there somehow a decoder connected to such a tuner via an antenna cable?
