View Full Version : High Definition(HD) TV channels in progress!
I want to know if TV with Multi-system will be able to support those channels :?:
no, you can not view these chanels on a multi system tv, you need first a HD (high definition) receiver and you also need an HD tv in order to watch the high definition chanels.
almost all plasma tv's are HD capabale and most of all your PC monitor above 17" is suitable for HDTV and SDTV reception. but all the way, you will require some equiment to receive HD/SD tv reception.
Thanks guys for gr8 support :)
Is there any channels started on Hotbird HD technology supported?

What is HDTV
A standard of digital television that is getting a lot of po....rty right now. It is called high-definition television, or HDTV. HDTV is high-resolution digital television (DTV) combined with Dolby Digital surround sound (AC-3). HDTV is the highest DigitalTV resolution in the new set of standards. This combination creates a stunning image with stunning sound. HDTV requires new production and transmission equipment at the HDTV stations, as well as new equipment for reception by the consumer. The higher resolution picture is the main selling point for HDTV. Imagine 720 or 1080 lines of resolution compared to the 525 lines people are used to in the United States (or the 625 lines in Europe) -- it's a huge difference!
The resolutions formats used in HDTV are:
* 720p - 1280x720 pixels progressive
* 1080i - 1920x1080 pixels interlaced
* 1080p - 1920x1080 pixels progressive
"Interlaced" or "progressive" refers to the scanning system. In an interlaced format, the screen shows every odd line at one scan of the screen, and then follows that up with the even lines in a second scan. Since there are 30 frames shown per second, the screen shows one half of the frame every sixtieth of a second. For smaller screens, this is less noticeable. As screens get larger, the problem with interlacing is flicker.
the above mentioned resolutions 720p, 1080p are also used in PC video files and thus refer to as HDTV resolution video format. A lots of new movies are availabloe in HDTV video format also and a few DVB tv channels are also broadcasting in HDTV video format allready.
here are some sources where you can download free HDTV video samples for your try in your PC

Thanks dear saed for prviding a deep search ,,I appriciate your efforts :)
It would be so nice if you could move above all stuff in a sticky column :idea: Thanks in advance :wink:
you are welcome, but only Fanta and Admin can make sticky threads in RDI-English section :D
saed
thanks for your valuable info, but is it possible to download these HD clips and watch them on an HDTV ready through connecting the PC to the TV?
saed
also i would like to ask you if we can watch those clips through downloading them , copying them on a CD and playing this CD on a HDMI DVD, and connecting this DVD to an HDTV ready, is it possible?
saed
also i would like to ask you if we can watch those clips through downloading them , copying them on a CD and playing this CD on a HDMI DVD, and connecting this DVD to an HDTV ready, is it possible?
if your HDMi DVD player supports the video format/codec of WM9, Quicktime or Divx, then YES, download the appropriate clip, put them on a CD/DVD and play them in your player. Mostly such DVD players suports DivX/MPEG-4 and WM9 video format. so give it a try, i am sure it will work if supported by your player.
saed

some high quality graphics card (vga card) now have a DVi output and if your digital tv has a DVi input socket then YES, connect your PC to your TV and enjoy!
saed
is it enough to have a dvd which support the dix x format or the mpeg4 format with an HDMI connection to watch an HD dvd or clip? or do we need another feature also?
saed

Yes, if your DVD player supports MPEG-4/DivX format than you can download and copy DivX/MPEG-4 video clips to CD/DVD and then can play on your HDTV capable dvd player.
Hey thanks saed. Very nice to see these types of stufs. Thanks for your info on HDTV. All the best

Dear Saed can you give more information ?
Blu-Ray Disc (BD) and HD DVD are next generation Compact Disc Media, a single layer Blu-Ray disc can hold upto 25GB data while a dual layer can store 50 GB of data.
For more info on Blu-Ray Disc and HD DVD media, look at this topic at Blu-Ray Disc (http://hvac.com.sa/technologic/viewtopic.php?t=71) and HD DVD (http://hvac.com.sa/technologic/viewtopic.php?t=72)
as HDTV media requires more space, here comes the need for HD DVD and BD to store them.
I have LCD TV, and watch non HD channel with non HD receiver.

what is the input of your LCD tv ? does it have DVi and/or HDMi ? a bad quality source can not be converted into good quality output.
Onput HDMI, because the signal from receiver is analog and the LCD is Digital signal. need sometime like analog to digital convertor
A Multisystem is a signal system used by many large Countries TVproviders.
NTSC is used by USA, Canada, and part of japan.
SECAM is used bt France
PAL is a commonly used by many large /small countries.Africa,
UK,Australian.India,NZ,FijiIslands,Japan-(part)HK,Malaysia,Indonesia,
Korea,Europe (-part),
Analgue,Digital n High Definitions TV signals format are quite differnt from Multisystems.
In Australia full Digital TVsignals will come into our Tv in 2012.
Currently, most of the larger Tv network are telecastin in Digital, via a standrad system so all Australian viewers can view it via their standard TVs.
but Australians can view such fullDigital signals via a Set Top Box, sold at under $100A.
High Definitions are still in the testing stages.
Analague signals are about to go out sooner than later.
Saudi Arabia has just started their DVB-T (digital video broadcast over terrestial) and now we need digital tv sets with dvb-t tuner or at least dvb-t receiver with analog output.
South Korea allready stared so many HD tv channels and they are enjoying HD broadcast allready. exaple MBC HD, KBS HD etc are HD tv channels. I envy them.

Forget about plasma and lcd. The up and coming format which blows everything currently on the market is SED Tv.
Which stands for: Surface-conduction Electron-emitter Display.
Basically It's an advanced version of your standard CRTV. When your current plasma's and lcd's lasts up to 60,000 hours, the sed tv after 60,000 hours only lose 10% of picture quality instead of breaking down completely.
SED TV – New Flatscreen Technology
Plasma and LCD HDTVs may soon be sharing shelf space at your local electronics store with a new flat panel technology called SED TV. Developed jointly by Canon and Toshiba; SED stands for Surface-conduction Electron-emitter Display.
Canon started development on this imaging technique back in the mid 1980s and joined up with Toshiba for the project in 1999. Both formed a dedicated company for the technology called SED Inc. in 2004. Neither of these companies is a notable player in the flat screen arena, but they are looking to make a big splash with SED TV. Test production runs are already underway with limited product availability expected by spring 2006. At present, it looks as if Toshiba will start manufacturing HDTV panels in earnest in 2007 barring any production problems.
How it Works
SED technology works much like a traditional CRT except instead of one large electron gun firing at all the screen phosphors that light up to create the image you see, SED has thousands of tiny electron guns known as "emitters" for each phosphor sub-pixel. Remember, a sub-pixel is just one of the three colors (red, green, blue) that make up a pixel. So it takes three emitters to create one pixel on the screen and over 6 million SED emitters to produce a true high definition (HDTV) image! It's sort of like an electron Gatling gun with a barrel for every target positioned at point-blank range. An army of electron guns, if you will.
This may bode well for video purists who feel that CRTs offer the best picture quality, bar none. One prototype has even attained a contrast ratio of 100,000:1. Its brightness of 400cd/m2 is a tad on the low side for an LCD TV and nowhere close to a plasma. This is expected to increase in the ...ure, but still works out to about 116 ftL (foot Lamberts) or more than twice a regular TV. To put this in perspective, a movie theater shows a film at about 15 ftL.
Life Expectancy
It does look like SED TVs will last a good while as it has been reported that the electron emitters have been shown to only drop 10% after 60,000 hours, simulated by an "accelerated" test. This means that it is likely the unit will keep working as long as the phosphors continue to emit light. That can be a while. Maybe yours will even show up on the Antiques Roadshow in working condition in the far distant ...ure. Time will tell but "accelerated" testing results should always be taken with a grain of salt as it only imitates wear and tear over time.
SED TV Compared to CRT
SED is flat. A traditional CRT has one electron gun that scans side to side and from top to bottom by being deflected by an electromagnet or "yoke". This has meant that the gun has had to be set back far enough to target the complete screen area and, well, it starts to get ridiculously large and heavy around 36". CRTs are typically as wide as they are deep. They need to be built like this or else the screen would need to be curved too severely for viewing. Not so with SED, where you supposedly get all the advantages of a CRT display but need only a few inches of thickness to do it in. Screen size can be made as large as the manufacturer dares. Also, CRTs can have image challenges around the far edges of the picture tube, which is a non-issue for SED.
SED TV Compared to Plasma TV
Compared to plasma the ...ure looks black indeed. As in someone wearing a black suit and you actually being able to tell it's a black suit with all those tricky, close to black, gray levels actually showing up. This has been a major source of distraction for this writer for most display technologies other than CRT. Watching the all-pervasive low-key (dark) lighting in movies, it can be hard to tell what you're actually looking at without the shadow detail being viewable. Think Blade Runner or Alien. SED's black detail should be better, as plasma cells must be left partially on in order to reduce latency. This means they are actually dark gray – not black. Plasma has been getting better in this regard but still has a way to go to match a CRT. Hopefully, SED will solve this and it's likely to. Also, SED is expected to use only half the power that a plasma does at a given screen size although this will vary depending on screen content.
SED TV Compared to LCD
LCDs have had a couple of challenges in creating great pictures but they are getting better. Firstly, latency has been a problem with television pictures with an actual 16ms speed needed in order to keep up with a 60Hz screen update. That needs to happen all the way through the grayscale, not just where the manufacturers decide to test. Also, due to LCD's highly directional light, it has a limited angle of view and tends to become too dim to view off axis, which can limit seating arrangements. This will not be an issue for SED's self illuminated phosphors. However, LCD does have the advantage of not being susceptible to burn-in which any device using phosphors will, including SED. SED is likely to use about two-thirds the power of a similarly sized LCD. Finally, LCD generally suffers from the same black level issues and solarization, otherwise known as false contouring, that plasma does. SED does not.
SED TV Compared to RPTV
SED is flat and RPTVs aren't. RPTV also has limitations as to where it can be viewed from, particularly being vertically challenged with regard to viewing angles. A particular RPTV's image quality is driven by its imaging technology such as DLP, LCoS, 3LCD or, more rarely recently, CRT. With the exception of CRT, these units need to have their lamps changed at various times but usually at around 6,000 hours, costing an average of $250.
Pricing
The cost of flat panels is largely dependent on production yields of saleable product. Nobody really knows for sure what this will be until real production starts, but new technology is always expensive in early production. If it works, the use of inkjet technology to make SED displays rather than the more expensive photolithography process used in LCD panels should help cost management. The first product release will be a 55" version at full HD resolution (1920x1080) priced comparably to today's plasma display panel (PDP) of similar size. That could be a big dollar difference by early 2007, as the price of plasma displays is expected to continue to drop.
Conclusion
New technology usually has its fits and starts, but on paper SED should be a strong contender. Will give you updates, as the technology gets closer to market.
(it was a cutting from "other" forum :) )
Thanks for the news Dear Masood.
But its an old news of October,2005. Thats true that Toshiba and Cannon were trying their best to put all efforts to make SED TV a succees, cheaper in price, loger life and better Quality then LCD/Plasma. They Planned to launch it before FIFA 2006 but they couldnot make it. Now they are eyeing it to be launched before Beijing Olymoics 2008. Which is a long run to go. Technolog of SED TV will still take time to get matured and till that time Better and enhanced versions of Plasma screens will be available. which will surely be cheaper in price, loger life and even more better quality. Plasma are allready in hands of consumers now.
A lots of companies (plasma manufacturers) are allready seeing a fall of SED TV even before its launch and the launch is going to take an indefinite delay.

dear saed,
I tried running HDTV on progdvb with Skystar 2, i added the H486 codec also and changed the filters but i still didnt get it running. Normal channels work but the HDTV doesnt open at all. I am trying to see ART World Cup Channel which is fta on nilesat 102 in HDTV mode
you can try h264 with the latest dvbdream.. see here:
(but for the moment it demands a lot of processing power.. maybe in the ...ure)

Try using AltDVB. AltDVB natively supports HDTV. A good codec is a must to improve HDTV reception. A bad quality codec will put a lot of strain on the processor and you will observe sound sync problems. I am able to receive HD channel from ChinaStar 1 using SkyStar 2 PCI and I am able to display it on my HDTV by connecting DVI port of the video card to the HDMI on the HDTV (through a simple converter).

I am using CyberLink decoder which is giving good results (CPU usage around 18%.
I am not using normal TV mode for viewing HD. I either use PC connection on the TV or the HDMI connection. If I feed computer S-Video out or Composite out to TV, the picture quality is way inferior although it is still displayed.

Right,what about progressive,i mean 1080p would be a big diference betwen 1080p and 1080i ?(talkin about satelite transmited chanels) thanx
1080p is better than 1080i. 1080p is 1920x1080 and 1080i is actually 1920x540 but doubled the frame rate.
Even 720p is better than 1080i, when we're talking about movies and news broadcasts and stuff where there's not much movement... only for sports is 1080i worth it.
