the future of high definition tv?
by AndyPeters1 - 8/13/07 7:10 AMRight now, HD shows are broadcast in 720p, right?
Will any shows be broadcast in 1080p?
Are there sets better than 1080p in the works?
As I remember the history of tv: We went from black and white sets to color in around 30 years. Then color to hd in around 40 years. We went from 720p to 1080p in like 4 months!! Next year are HD tv's with 3050p going to be coming out?
Is there a new high def technology being developed different than lcd/plasma that we might see next year? will the whole LCD vs. plasma debate fade away?
sorry for my ramblings, but i'm looking at the near future (2-6 years from now). Thanks for any help!
Well
by ozos - 8/13/07 7:35 AM In reply to: the future of high definition tv? by AndyPeters1You have some interesting ideas, most current HD broadcast is either 720p or 1080i, currently 1080p requires too much bandwidth to broadcast on a mass scale (so 1080i is used, there was some discrepancy with either DirecTV or Dish Network (don't remember which one) over their 1080i broadcast not being full frame 1920x1200)).
Currently Plasma and LCD are fairly cemented in place, Plasma because it offers unbeatable black levels and perfect clarity, LCD because its "thin and adorable" making it easier to market, and its also more power efficient/light weight (a ~37" CRT weighs a few hundred kilos, a 42" LCD is about 20-25 kilos).
There are a few other technologies in the works, for example SED, LaserTV, DLP (which has been gaining ground), OLED, and so on, however they all face political and economic pressure.
2560x1600 has been considered as an HDTV format from what I've read, at 1600p, however the bitrate would be higher than most current storage media formats could support (the reason HD-DVD/Blu-Ray are being pushed is that they provide enough storage for 1080p60 content, DVD simply doesn't (consider LOTR3 Director's cut)).
There is also some research on UltraHD, which is some absurd resolution (as I recall 7840x2560) but in trial testing some of the test viewers reported experiencing motion sickness (if that gives you an idea how high is too high to watch at point blank range).
Currently I don't see HD formats changing for some time, while DVR devices may be capable of storing and accessing 1080p60 content, optical media currently isn't quite there, and display devices certainly aren't there (at least not in the range that most people can afford).
the LCD vs Plasma debate is likely going to result in LCD being the victor, mostly due to marketing and production capacity (consider how many manufacturers sell PDPs vs how many sell LCDs), generally I feel LCD to be an inferior technology, however it markets better (there is no arena its ever gone to competition in, that its won in terms of quality, price, etc, consider: for mobile devices we have OLED, for projectors we have CRT, DLP, and laser, for computers we have CRT, for TVs we have DLP and CRT RPTV, CRT, and PDP)
I don't think we will get any more quality viewing...
by ahtoi - 8/13/07 9:49 AM In reply to: the future of high definition tv? by AndyPeters1with any higher resolution than 1080p. My guess on the next break through would be 3D.
way too far out
by ozos - 8/13/07 10:57 AM In reply to: I don't think we will get any more quality viewing... by ahtoi3D video would be, amazing, but thats like decades off
1080p is still limited in resolution compared to whats available at the commerical level (Digital Cinema 2k and Digital Cinema 4k)
theres still much to come
well maybe, but...

ANDY WHAT ARE YOU WAITING FOR?
by stewart norrie - 8/13/07 12:59 PM In reply to: the future of high definition tv? by AndyPeters1Its here and now. All broadcasting is standarized 720 and 1080I are the norm+ 5.1 audio Believe me with a good 1080I t.v.+ hi-def satellite or cable system You will have picture quality as good as any movie palace in town + once you add the hi-def package you will have programming thats out of this worldAlso dont worry about all the new bells and whistles that are coming down the road most technology like 1.3 will only help improve ultra hi-end home theater installations. WHAT ARE YOU WAITING FOR? stewee
1080p
by AVMack - 8/13/07 1:58 PM In reply to: the future of high definition tv? by AndyPeters1HD shows are broadcast in two formats 720p ( progresively scanned )& 1080i ( Interlaced ) . Fixed pixel displays such as plasmas & LCDs show all input resolutions at thier native resolutions ( Pixel Count ) and scan progresively . With this in mind , a 1080i source input into a good 1080p set should look superb .
I don't see much changing in the future....
by retexan599 - 8/17/07 5:23 PM In reply to: the future of high definition tv? by AndyPeters1...as long as the average home living room or den stays at about current typical home dimensions. The only reason (in my view) for High Definition TV is to accommodate the larger screens. My current HDTV is a 50 inch diagonal plasma, and it is just right as a size for my living room. If I had, say, a bedroom-sized living room, I do not see a need for a TV larger than 25 inches which works great at Standard Definiton. So, unless a person lives in a mansion, I don't see a need for something much bigger than the current 50 to 60 inch TV's; and by inference, no need for higher definition than what we have now. I think one reason that neither HDDVD nor BluRay have taken over is that there is not that much incremental difference in high defintion at current sizes of TV's. That is my two cents....
SORRY YOU CANNOT COMPARE S.D TO HI-DEF
by stewart norrie - 8/17/07 7:20 PM In reply to: I don't see much changing in the future.... by retexan599After enjoying my huge 72" hi-def set for 2 years I would go blind trying to watch a s.d. set unwatchable but I do agree that it is a waste of time and money for tiny screen sizes stewee
you can

With various studies done at the university level to assess how well a person can percieve the resolution (projectors were used (the same projector) to ensure the same screen size) an HD clip was played of a movie, and then a terrible condition clip of the same movie was played from VHS (bad conditoin VHS), as I recall only about 10-20% of viewers reported noting the reoslution differences
Its the same general principle of computer gaming, frame rate and resolution are bigger marketing terms than they are realities, while 5 FPS is noticable, you won't tell the difference between 30 and 3000 FPS.
With resolution, its the same thing, granted, a 72" TV running 720x480, could look pixelated, depending on the input source, however nothing is to say it would look pixelated, it could also look wonderful.
Its all a matter of perception, viewing distance, desired quality, input medium, etc, yes a 70+" TV running 1080p would be very nice looking, but if you moved a tad closer, you can drop some size off of the TV, and resolution, etc...
Please note, I'm not trying ot make any specific point, just pointing out a simple geometric truth that has been in recorded human knowledge for some time (Plotinus, as far as I know, first explored the concept of finite resolutions, depth of field, aspect ratio, etc that was close to 1700 years ago, Euclid also explored aspects and dimensions, however never specifically stated resolution as part of the equation)
