thats true overall PQ of assto needs to be improvd. My 46 LCD was on assto thru Yamahaa avr which upscaled the feed and PQ on LCD seemed okay.I just removed the LCD to my room, to use it on my 2nd decorder,and now without avr upscaling OMG the SD picture is so bad while HD is fair,now I realise how much of work my avr has done! MPEG4 feeds of suntvv is okay the worst are our In House channels. astro is Not picture perfect.

According to what I read from your comments here, it is
PARTLY correct to say that the Byond PQ become so bad
without using the Yamaha AV Amplifier for the 2nd Byond decoder in another room/main room/hall.
This is what I understood from your comments here so please correct me if I am wrong...
a) Have 2 Byond boxes. 1st Byond in your room and 2nd Byond in another room/main room/hall.
b) Tested with your 46in LCD TV on 1st Byond with connection through Yamaha AVR.
c) Took the same 46in LCD TV to 2nd Byond and connect so no Yamaha AVR.
Since you used HDMI connections for BOTH your Byonds, why take the trouble to temporarily move your TV to the 2nd Byond to test ? Just test using the 1st Byond. First test with
Byond >> to Yamaha >> then to HDTV. Then second test with
Byond >> direct to HDTV. You can test this same way without "moving" your 46in LCD TV to the 2nd Byond box in another location.
Mmm... unless you tell me that the 2nd decoder is the Old Astro DMT box, not Byond, so of course the PQ from the old Astro DMT box is terrible ! If true, its not correct to make comparisons between the Byond box and the old Astro DMT box.If you used only HDMI connections to test compare, its only PARTLY correct to say that your Yamaha AVR improved the PQ a lot by "upscaling" the SD channels.Video ScalingRefers to resolution used such as 576p (852 x 576 px 4:3), 720p (1280 x 720 16:9) and 1080i (1920 x 1080 16:9) for Byond. Actually 576p is generally not regarded as HD and the 852 pixels may be slightly different for different video standards.
Video "Upscaling" means changing from lower to higher resolution which may include changing from 50Hz to 60Hz. Example... Upscale 720p original video ratio to 1080i resolution. I
think (not sure) that upscaling can also occur from the source player (such as the Blu-Ray player, Byond, etc) when the source player setting is changed.
Video ProcessingRefers to the video processing by different video processor chips. The processing includes controlling the Brightness, Contrast, Colour, Sharpness, White Balance, Colour Space, Gamma, Black Tone Levels, and others. The better the quality of such processors the better the PQ and the higher end ones also allow users much more control to adjust the settings. Because of the wrong factory adjustments and lower quality video processor chip used in many budget HDTVs, this is where the Professional Calibration person come in, who used specialised devices to fine-tune the HDTV to achieve the best optimum PQ. One among many video calibrator devices used is the Spyder4Pro which I really don't know whether it is the best or not.
Hehe... to "Anfieldude"... did I make any mistakes here ?Here is the interesting thing about the Yamaha AV Receiver Amplifiers which have HDMI... I am quite sure that almost ALL such Yamahas do NOT upscale any video connected to its HDMI Input. My present 2 Yamaha AVRs are the 3rd and 4th ones after replacing the previous ones. My Yamaha AVR Manual definitely states this clearly.
You can test whether your Yamaha AVR actually "upscale" the video or not... just by looking at your HDTV display Info.
I am absolutely sure for my Yamaha AVRs, RXV-1900 and RXV-3900. Here was what I did. Byond HDMI out to Yamaha... then from Yamaha HDMI out to my Samsung HDTV.
On my Samsung HDTV Remote, there is an "INFO" button which when pressed, will display on the TV screen the Video Resolution received from its own inputs.
With my Yamaha HDMI Output still connected to my Samsung HDTV, I then changed my Byond HD Settings to test...
1) Byond 576p setting... my TV info shows 720 X 576 @ 50 Hz.
2) Byond 720p setting... my TV info shows 1280 x 720 @ 50 Hz.
3) Byond 1080i setting... my TV info shows 1920 x 1080i @ 50 Hz.
* 50 Hz because our Malaysian TV system is PAL.
As you can see, there is absolutely
NO UPSCALING from the Yamaha AVR
when HDMI is used (from Byond HDMI to Yamaha). IF there is any upscaling, all three Byond settings will show on my Samsung HDTV as only 1920 x 1080i @ 50 Hz BUT its not.
So, part of your comment "
was on assto thru Yamahaa avr which upscaled the feed and PQ on LCD seemed okay" should be corrected to "
was on Byond which feed HDMI to Yamaha with better internal Video Processor improved the PQ which seemed okay".
I do understand what you mean about the Yamaha which improved the PQ. My Yamaha have the Anchor Bay video processor chip and Burr-Brown audio processor chip. It seems the Marvel QDeo Video Chip used for my Oppo BDP-93 is much better than Anchor Bay. Denon AVR usually used Audyssey Video Chip.
I admit that I am a bit picky on the "upscale" word that you used to describe PQ improvement. PQ Improvement is NOT because of "upscaling" from HDMI. Actually the Yamaha video processor chip do improve the PQ slightly because of better noise reduction, colour interpolation, etc.
My apologies if I have offended you.
I can suggest that you can test with Component Video (Red, Green Blue) connection to see if your Yamaha improve the PQ for upscaling from Byond 576p to 1080p. Test using only the Byond "HD Setting" at 576p. First test, connect Byond Comp Vid directly to HDTV. Second test, connect Byond Comp Vid to your Yamaha AVR, then from Yamaha HDMI out to HDTV... your Yamaha will now definitely upscale the Comp Video Input to HDMI Output as 1080p. Must make sure your Yamaha internal settings set to (1) Video Converter... ON (2) Component I/P... ON (3) HDMI Resolution... 1080p so correct it if necessary. Now, at least you can make a more fair comparison of upscaling improvememt to PQ.
Actually I don't know what cable connections you used for your PQ tests so I assumed you tested with HDMI connections only.
