I have a 31 inch 1995 Panasonic XF series TV with superflat data-grade picture tube. I like the set's sharp picture, vibrant color, and the ability to adjust the set in a number of ways. I believe the set has a 800 line picture tube.I was wondering if there is anyway to upgrade or convert it to recieve digital signal? Also, if I can convert it, is the benefit worth it?
I haven't checked for previous posts on this subject. If the topic has been well discussed, please excuse.
I can use my set to view an analog conversion of digital signal. However, I cannot view a a HDTV transmission at the intended HDTV resolution without a true HDTV set. Since I already have digital cable, I suppose then that I am already seeing the best picture I will ever see on this set.
DTV and HDTV are terms that are often tossed around but are largely misunderstood.Digital Television(DTV) is simply broadcasting Television signals in digital rather than analog. So if you currently have DBS, essentially you have DTV. Much of the debate on DTV is how(which format VSB vs COFDM), and when the switch from analog to digital signals will happen for the broadcast stations ABC, CBS, FOX, NBC, PBS.
Now HDTV describes several picture formats beyond the current Standard Definition Television(SDTV). SDTV is 525 interlaced lines(525i) in 4x3 aspect ratio. HDTV formats range from 480p, 720p, 1080i etc in possibly a 16x9 ratio. The 'p' stands for progressive scan. And these new formats will be available in DTV.
Some Manufacturers, Media, Organizations describe a display device as being DTV compatible or capable. This is a cause for confusion since there is no format standard defined for DTV. So when you see a display device claiming DTV compatability, don't be suprised if it is just SDTV.
Yes, you can buy a DTV receiver now, but there are very few programs to see. And yes the output of a DTV receiver is still analog. And your current TV should be able to connect via S-Video to a DTV receiver. Obviously if you want to get HDTV then you'll need a display device that supports VGA or Component Video to view the new formats.
There is still a lot of issues with Broadcast DTV. I would suggest a wait and see approach. If you must upgrade to an HDTV set, I would suggest getting one without the DTV receiver since it's still not clear which transmission format they will be using.
Hope this clears this up. If not check the link.....more info than you'll ever want on this subject.
You can get a converter which will allow you to receive digital TV signals. For example, I just switched out my cable TV box to a new one which allows this. In that case, I got a lot more channels, with and a better TV guide feature.OTOH, under the assumption that digital is the prelude to HDTV, you cannot view TV at high def levels with your old set. It won't have the circuitry required. So, in the future, when HDTV is out, you'd be at best viewing a HD signal that's been down converted to standard resolution.
Ultimately, you'd have to get an HD ready tv, and an external HD box. Similar to how preamp/pros first came out as AC3 ready, and required an external AC3 decoder box. At some point, I'd assume the two products would be merged into one.
At least, this is my understanding of all this.
... and I would assume the USA situation will be the same. These convertors will be the first option for most consumers in the lioght of the high initial digital set expense.Peace at AA
