General Digital FAQ

1. Do I need an antenna on my roof?

Yes, this is advisable for all installations. In most cases, you will not need a new antenna, so long as your existing antenna is reasonable. You may need better cabling. We suggest quad shield coaxial cable.

2. Is digital in my area?

If you're in a capital city, then yes. If you are in a regional area, it is more than likely - but check by calling your local TV stations first.

3. Do I need a new TV?

NO! We’ve connected a digital television box to a 40 year old black and white television set and it worked well. We’re yet to see a television it doesn't work with.

4. Can I use my VCR to record digital television?

Yes, you need to plug your box in using RCA leads, and select the line input of the VCR to record though. This is typically L1, 0, 1 or AV.

5. So is the picture and sound really better?

Yes – the picture is just like DVD and the sound is better than many DVD's. In fact, broadcasters are finding they have to put a lot of effort into their shows now. As an example, the entire set for The Tonight Show with Jay Leno had to be re-done from scratch because viewers were complaining about the shoddy quality of the set! These faults never showed up on analogue transmissions!

6. What’s widescreen?

See this page.

7. Is pay TV re-transmitting digital channels?

No, pay TV is providing analogue retransmissions.

8. What’s Standard Definition? (SD)

Standard definition is many more lines (resolution) than what you are looking at in analogue. SD is transmitted at 576 vertical lines of 720 horizontal dots each. This is commonly called 576i (the i stands for interlaced) Everything except the High Definition demo loops is broadcast in SD and can be viewed on any TV.

9. What’s High Definition? (HD)

According to the government, High Definition is anything above 576 lines, with 720 dots each in interlaced format. So the basic specification is 576p – the p stands for progressive scan. It’s just a different way of transmitting the information. There are other HD formats, among them, 1280x720p and 1920x1080i

10. What extra channels are available?

Channels are different in each area. For example, in Hobart, you can get TDT - a digital only channel. In metro areas you can get SBS world news channel. In Sydney you can get channel 4 Datacasting - similar to Austext.

11. What’s interlaced mean?

TV is transmitted in frames, just like a cartoon is a bunch of pictures put together to represent movement.

When a picture is interlaced, only half the picture is displayed at a time, so you get lines 1,3,5,7 etc. sent through 25 times every 2 seconds. After the odd lines are sent, the even lines, 2,4,6,8 etc are sent. The television then puts these together to form a different picture, 25 times every second. It is only changing half the picture though, every 25 seconds.

12. So what’s progressive scan then?

Progressive scan pictures contain the entire picture 25 times per second or 50 times every two seconds. Compared to interlaced formats at 25 times every two seconds, you get twice as much data. This means the entire picture is refreshed twice as much, giving smoother lines, smoother motion, perfect pause frames and higher brightness levels.

13. What are closed captions?

See this page.

14. What are the different formats?

SD 576i = 576 x 720 625 Lines 50Hz interlaced 15.625 kHz 5-6Mbps

HD 576p = 576 x 720 625 Lines 50Hz progressive 31.250 kHz 10-13Mbps

HD 720p = 720 x 1280 750 Lines 50Hz progressive 37.500 kHz 10-15Mbps

HD 1080i 1080 x 1920 1125 Lines 50Hz interlaced 28.125 kHz 13-15Mbps

You can see that the High Definition signals have almost twice the resolution of Standard Definition signals (1125 v 625). Also, the amount of data (Mbps) is up to three times as much. You need a high definition display to take advantage of this though.

Strong FAQ

1. Can the 5390 be used to record pay TV?

No.

2. Can the 5300 be converted into a 5390 (add a hard disk)?

3. Can I record something and watch something else?

Only if it is already recorded on the hard disk. There is only one tuner in the 5390.

4. Will the 5390 record closed captions?

No - the Topfield TF5000PVRt will though
