  1. Thanks AlanH, I think you meant that for every 3 real pixels, one interpolated pixel is created... Is it likely that my plasma can only display at 75 or 100Hz, because you have to choose one or the other, I don't think it allows you to display the native scan rate of the input... On that matter can't see why the plasma can't accept 75 or 100Hz over VGA, the maximum is 60Hz at 1280x768, any ideas? When I input 720p, doesn't the display scale to 1280x768, or does it leave it at 1280x720? Tony mentioned that our 1080i is 1440x1080 non-square pixels, how can the display work with non-square pixels when it has square pixels? Thanks, Ben
  2. how does the display downscale from 1440x1080 non-square pixels to 1280x768 square pixels (my Pioneer 506HD plasma)? sounds like a very complicated scaling process and I don't see how it can be done very well... also have some questions about refresh rates if you can answer them: 1. does each display usually operate at only one refresh rate? i know my pioneer 506HD plasma display has user selectable 75Hz and 100Hz scan rates: 2. are these the only two refresh rates that it operates at? 3. if 60Hz is input, how does it convert to 75 or 100Hz, just multiply some frames and not others? i would think this would create judder or some other problem... 4. the pioneer 5060 over VGA will only accept 1280x768 at a maximum of 60Hz, why wouldn't it accept 75 or 100Hz if these are its native scan rates? 5. all our SD and HD TV broadcasts are at 50Hz, my Pioneer can select between 75Hz and 100Hz display, what suits each of 576i, 576p, 720p and 1080i? thanks, ben
  3. Once a threshold is reached (ie complete image with no pixellation), does further picture quality increase occur with increased signal strength? Thanks, Ben
  4. thanks Tony, but if your display doesn't have non-square pixels, doesn't image distortion arise?
  5. On this link http://www.dba.org.au/index.asp?sectionID=15 it says that 1080i is 1080 horizontal lines interlaced x 1440 active pixels. I always thought 1080i was 1920x1080. Also, is the format of SD DVB-T exactly the same as DVD, ie when on an HTPC you want to burn a recorded program to DVD does your software need to change the encoding? Thanks, Ben
  6. anyone used the miglia or elgato usb sticks? from the mac store reviews seems like the miglia does more with the signal than the elgato (ie reports much higher signal strength) and therefore better picture...actually that's one thing i have wondered about digital tv, it seems better signal strength improves the picture quality but i would have thought that above a certain threshold, no more increase in PQ would be possible because digital is all or nothing...
  7. Hi, Just wondering if anyone can recommend USB2 DVB-T tuner for my new MacBook Pro, want to use it as a PVR for digital TV (including HD). I have a subscription to IceTV so integration of the software with IceTV is important. Also, what is Webscheduler? Sounds like a recording program, is IceTV better if that is the case? Thanks for any help, Ben
  8. Hello, Just wondering, since the Pioneer 506HD plasma display only accepts native rate over VGA input, would this produce a "better" picture hooked up this way, or would the advantages of a digital connection in DVI-D/HDMI, even if it is at non-native rate of 720p or 1080i, be a better connection? If using the VGA input, I assume you set the resolution from the computer to 1280x768, but what frequency will work best? Thanks, Ben
  9. took my DVH-505 to where I bought it (Carlton Audiovisual) and it is faulty, being sent back to Digitalview...
  10. OK, cool, actually I only read the first page of this post, didn't realise there were 24 pages... What is the current opinion regarding the best PQ of the HD-STBs at the moment (eg the Topfield and Teac boxes mentioned above), and the connection type, I only have one HDMI input on my Pioneer 506HD plasma and I use this for the DVD player, would prefer not to get an HDMI switcher box if component can produce similar results... Thanks, Ben
  11. OK, good thought...the resolution of my panel is 1280x768 though so it couldn't be losing 312 pixels, and besides the problem exists when I output 576p and 720p...will give digitalview a call Thanks, Ben
  12. Does the AUSID output the native resolution of the broadcast over component? ie if 576i broadcast it sends 576i, if 720p sends 720p, if 1080i it sends 1080i, or do you have to specify ONE output resolution? if this box doesn't output the native resolution, which boxes do? thanks, ben
  13. Thanks, but I understand everything about scaling and deinterlacing, the problem I have is being able to send the native broadcast resolution and native interlaced or progressive setting direct to the display the box having to interlace, deinterlace or scale. For example, component will only output 576p, 720p and 1080i and you have to select only ONE of these resolutions. So if I choose 1080i, that is fine for Channel 9 and 10 HD, but for all other channels, interlacing (for 576p and 720p) and upscaling (for 576i/p and 720p) will have to be performed by the STB. If I choose 720p, that is fine for ABC HD but for all other channels, deinterlacing (for 576i and 1080i) and upscaling (576i/p) or downscaling (1080i) will have to be performed by the STB. I think the video processor in the display would do a much better job than the video processor in the STB, that is why I suggested connecting via BOTH component (for HD) AND S-video (for SD). I suppose if I want the native resolution to be sent for HD then when I watch a program I set the output of the STB to match that of the broadcast. The original issue that I still haven't worked out is when I send the 16:9 image to my Pioneer 506 plasma, the top and bottom of the image are cut off, like it is zoomed, but I can't find any setting consistent with this. Thanks for any help, Ben
  14. Actually, I made an error with the aspect ratio, when I output 4:3 from the DVH-505, the picture is stretched but I can see the full picture, when I output 16:9, part of the top and bottom of the picture are cut off, so it must be a panel setup problem, but I do not have any zoom function activated. Anyway, if a 16:9 signal is sent to the panel, it should automatically display it correctly. Any ideas? Peter G, I can play SD 576i via component, so is the box doing the deinterlacing? In this case, I think the video processor in my panel would deinterlace better, so should I also connect via S-video so I can send 576i for SD? Thanks...
  15. Hi, To get the correct aspect ratio on my Pioneer 506 plasma display, I need to set the aspect ratio from the Digitalview DVH-505 HD-STB to 4:3. Any ideas why this may be so? Also, the manual says the STB does not support 576i over component video, which is the way I have it connected to my display, does this mean the STB is deinterlacing first? If yes, I would think the plasma would deinterlace better than the digitalview so for SD I should connect via S-video... You also have to set the video format to 576p, 720p or 1080i, then the box seems to convert to this format before outputting over component (ie I currently have the output set at 1080i, and no matter what the native broadcast format is, my plasma detects a 1080i input, so for example with HD broadcast at 720p, the box must scale to 1080 lines and INTERLACE, is this true?) If this is so, is there any way to send the native broadcast format automatically? Thanks, any help would be much appreciated, Ben
