Reliance digital to provide 250ch with HD LIKE quality
- Thread starter adder
- Start date
How can someone offer HD or even HD like quality?
Remember, the very basic law of physics. -Nothing can produce itself without the source.
The density of pixels should be at the very first point- while shooting the video with FHD cameras and not by so called upscaling by adding more lines of pixels. Now how many channels we have in India where all the recordings is done on HD cameras?
The SD content DTH companies provide is much better than the HD ready hype, as they show near "original like' video quality.

Actually if upscaled properly, the content can appear pleasing. For example, BD players do a reasonable job in upscaling DVDs.
Well, this is very subjective and perception thing. According to my personal and few friends observations, 480p output of DVDs looks crystal clear than upscaled one which adds artifacts. Tried and tested with many players and display combinations.
No doubt original 1080p blu ray will always beat DVD at full output due to extra lines of information and colour depath.
That CAN work, however all the Players, AVRs, STBs and in the end TV does this upscaling without further compression so it will look better.
In DTH operators, they will upscale, add synthetic pixels and lines and try to do extreme compression of this content which will most probably look WORSE than using the same compression on the original SD video and let the upscaling be done by the end devices..
Even if you send 480p or 576p to the TV, it will anyway be upscaled to the TV's native resolution.

I think it depends on a number of factors.
First - upscaling is done by algorithms which will create additional pixels based on the actual pixels. The better way its done, the better output it produces. This process can become complicated with fast changing pixels, as with fast moving images like in sports and the results will vary. So better processing will make a difference here.
Second - If I am using a 1280x720 disc and my player upscales it to 1920x1080 pixels but finally my TV only supports 854x480 pixels, the TV will downscale the image it receives which will result in lower quality picture than what I expect.

You are right here. The display will upscale to its native resolution and genereally TVs are good upscalers. But the point is there will be only 1 level scaling. The source which is playing the content (i.e: player) is not doing any additional processing.
Correct sir. Better correct signal (native to content)at source better will be upscaling. The dislpay will anyways try to upscale it. So playing 720p disc on 720 player output will give you best signal. Thats why the display looks awesome when all are 1080p, the blue ray disc, player and FHD TV which does no upscaling.
If the original video is 480i or 576i, then conversion will still happen to p. Also, even if we use the same output resolution as input, some devices STILL SCALE for some strange reason!!!
Absolutely... better they concentrate in giving us DVD quality video and CD quality audio.

Actually the problem is not 'upscaling' per say. The quality of the scalers built into DVD players can vary greatly. But the fact is, that a good DVD player, not one of the cheapo Rs. 5k - 6k players, can do a pretty good job of upscaling. Ofcourse all upscaling is subject to the original source being good. The old addage "garbage in, garbage out" applies to scaling as well. But, you should see how good an upscaled SD picture looks when upscaled via a player like the Oppo BDP-83 or BDP-93.
Unless it gets compressed again which is the main concern with DTH broadcasts... Even after excellent upscaling, they would have compress it again to broadcast.
Like I had speculated first, its just the upscaling on the NON DVR HD STB of Reliance.. They must have uploaded a firmware upgrade which enables upscaling to 1080p on the STB from 576i SD input (most sensible as I have always vouched for). All other HD STBs also does upscaling but only till 1080i (currently). Another silly marketing (like "Asli" HD of TS and "250 channels in HD like" by Reliance) to compete with Dish FraudHD!
Re: Output Resolution on Reliance HD STB.
Is there anyway one can change the output resolution say from 1080p to 720p on Reliance HD STB? Please advise.

The very fact that some SD channels looks way better than others on the same display, using the same STB, even when the cheapo DTH STB does the upscaling, strengthens my belief in the statement "garbage in - garbage out".

Re: Output Resolution on Reliance HD STB.
The Reliance HD box is a very basic one. There is no setting for changing the resolution. I am using a 26" LCD which is 720p or 1080i with the stb.

Yeah. So is there any new channels coming up on reliance, particularly on HD?

I think there are seven or eight HD channels, a list of which is available in another HD comparison thread.
