Display technology; resolution/zoomed data compression; DTV/hdmi ?

Digital TV was adopted by FCC in 2007. It made computers obsolete with 16:9 aspect ration wide screen. To play movie or show tV news or programming, you need mpeg4/h.264. Some smart fellow changed mpeg4 to mjpeg+mp3 so that mpeg2 can be converted to mpeg4 for data compression ratio advantage. The hidden advantage that computer people did not catch on is the zoom feature. Reduced pixel transmission became a natural. Reduced pixel count per webpage bacame a form of data compression. Easily done if resolution can be evenly divided. Computer video designers are still behind times not taking advantage of simple ratios.

Data compression of zoom technology is fast because of using FPU, without using GPU(cell processors). Tablet circuits have been simplified to hdmi connector..

This cutting edge technology has put IBMPC out of favor. Cost of computer are now one fourth of the old PC architecture. It is now hard to sell IBMPC, which IBM gave up years ago. Now HP wants to sell their PC business(2011 NEWS).

In computer design, simple architecture of mainframe computers is first, then software data compression standards are next. Reduced pixels of two stages with correction can now handle upto 100x data shrink for transmission on the internet. Twitter has been successful to reduce high resolution digital pictures to thumbnail assimulations(resemblances). Now Twitter is working on ondemand servers to consolidate data links and transmit a whole webpage from one server.

Cloud computing will never be the same. Speed of data streaming via wifi is traffic controlled by browsers(turn on/off radio signals ondemand).

Re: Display technology; resolution/zoomed data compression; DTV/hdmi ?

Since 2007, the video standards have been changed. Many computer manufacturers predict all video will be hdmi(no more vga/svga/xga). It is the zoom technology as a data compression method on the internet.

There are many data compression methods. Zoom is better than many. The only one still improved each year is prml on hdd and flash memory(multigated flash transistor). ASCII codes are no longer useful unless converted into color pixel video page, then mpeg4/h.264

Many webpages are now going through shrinkage of pixels. Many website claim their speed improvements. It still depends on data compression methods they use?

Re: Display technology; resolution/zoomed data compression; DTV/hdmi ?

Turned out, the display technology is the basis for paperless society.

There is no other way but, store the data and display on a screen to replace paper. One screen can replace millions of pages pf paper.

This means we have to work on data compression to store more data. Also, to reduce the display content to do display of content faster.

So, complicated digital video protocol will be reduced to analog pixel displays. Use a chipset to convert Mpeg4/h.264 data to RGB signals for lcd panel. this is the new 16:9 wide screen hdmi resolutions.

The data content is now zoomed to reduced resolution of pixels for data storage, much like digital cameras technology. This brings on the new cellphone design, not just telephony but event recorder, video and audio.

The fact that anyone with a cellphone can send news events to TV stations will prove the productivity of cellphones.

Re: Display technology; resolution/zoomed data compression; DTV/hdmi ?

TV display is now 480i/p, 720i/p or 1080i/p. These resolutions are direct conversion from hardware chipset. doesn't require calculation on GPU. So, its fast. For many of use video data from digital cameras and TV cameras can be directly transferred.

480i has different appearance than 480p. 480p is sharper than 480i. That means i is for TV and p is for monitors with real pixels to display. TV has less pixels on the screen so it has to be interpretive(i).

But, this technology prepares you to extend your hardware display screen one step further on interpretive resolution. Or one more larger screen picture that your smaller screen can see.

Why are we concerned about direct display of video from TV news or movies doing direct display faster? It is because we want to simplify the video protocol and concentrate on data display not too many compromising video protocol.

This leads to cost reduction in hardware design, and its the major reason IBMPC is being obsoleted by cost being too expensive(vga is 4x cost of hdmi) and data processing being too slow.

Data processing using USB ports are faster and cheaper too instead of going from cpu cache to ethernet packet format. All data transfer in USB  helps to save time(no conversion to different packets).

When you buy the cheaper tablets, you will see all these technology in play.

Footnote:
480i is interpretive but the technology is very old used by IBM 8415 monitor. Its called interlaced video technology  which extends resolution upto 2x by higher frame per second and shifting pixel display..

Re: Display technology; resolution/zoomed data compression; DTV/hdmi ?

Computer technology is going through technology improvement, and the old IBMPC is now obsoleted. The major move is radio transmission using TV technology of IF discriminator and time delayed multiplexer for more data channels for parallel data processing. Then the console has to be changed to RGB color pixels for data compression using mpeg4/h.264 protocol for video standard.

Console used to be ascii codes, now its in pixels transmission. Major video data compression is reduced pixels(high resolution to thumbnails) by zooming ratio change using FPUs and video correction technique, not graphics processors any more.

These major shifts in technology resulted in very serious cost reduction of data storage, and speed of data transfer using reduced number of pixels per page of data. Mobile text online banking is the most obvious benefit.

Re: Display technology; resolution/zoomed data compression; DTV/hdmi ?

kernel mode of Linux is to control the use of the multi fps display scheme. Intel and others are expanding upto over 1000 FPS to display super imposed pictures by using many frames of picture overlapping each other.

This resulted in a waste of cache memory(gB) for each frame of picture to be super imposed. But it also made drivers very complicated, and cpu overworked.

Many distros learned to avoid kernel mode to set FPS speed. Got back to the old display one frame per picture.

If you need silverlight of five layers of a picture, then you consolidate them by a single frame of mpeg4/h.264. this reduces number of super imposed layers of a picture back to one frame. Cpu will be used very little. Graphics accelerator is no longer needed. And zoom can do reduced pixels for each frame to speed up transmission on wifi. Silver light technology is used on DTV in the Mpeg2 digital camera for adding info(3D layers or notices and advertizing) on picture. To control wifi traffic, silverlight data must be consolidate and compressed for transmission. DTV has been using mpeg4/h.264 to do this job, and quality of service which is data integrity in transmission had been steadily improved since year 2007.

Re: Display technology; resolution/zoomed data compression; DTV/hdmi ?

Metro in windows8 is not rich experience. Its html5, css and realtime OS in webpages. It has to change from css to mpeg4/h.264 then add Dolby mobile sound with echo technology. This rich experience(reduced pixels by zoom technology) needs download manager to download webpage.

Windows8 then will catch up on iOS and exceed their rich experience without Dolby mobile sound.

The technology just moves right along. Very little changes made the new standards easier to implement.

Re: Display technology; resolution/zoomed data compression; DTV/hdmi ?

In recent years, superimposed video pictures were the rage, which was handled by silverlight, 5 layers of video pictures. It was compressed by mpeg4/h.264 easily. But if you don't use mpeg4/h.264 then you need video technology that has very fast frames per second solution, then view the single superimposed picture with huge memory deployment. If became the beginning of PAE in IBMPC. Intel contributed their drivers in Linux kernel(KMS). Many older cpus in older computers continue to use mpeg4/h.264 with ease. You can even do it in smartphones with WebGL(25 frames per second) and html5 or activex. WebGL(3D) can accelerate the 25 frames to do silverlight with only 5 layers of superimposed video frames.

So why should Intel push PAE to sell more wintel? They have no other technology to go? KMS in Linux kernels was an option that many had to defeat. Over 1000 frames per second really had no application to do slow motion type of solutions.

So, we have to leave KMS out?

Re: Display technology; resolution/zoomed data compression; DTV/hdmi ?

In conclusion of video solutions, new technology of video cards are lacking.

WebGL will be here for sometime to come. Data compression of Mpeg4/h.264 will be sufficient until slow motion applications are here in camera hardware.

Our eyes are only good for 1/25 second video presentation. What is Intel thinking 1000 frames per second, unless it can be slowed down to 25 frames per second to show slow motion.

Re: Display technology; resolution/zoomed data compression; DTV/hdmi ?

Silverlight is not a new technology by Microsoft. It is an adaptation of TV station cameras hardware using mpeg2 with five layers of superimposed pictures. This Mpeg2 was able to be converted to mpeg4/h.264 when mjpeg and mp3 were used for mpeg4/h.264.

This information is necessary to know what to do with video technology unified by digitalTV(FCC) in the united states.

This is how interactive TV will unify all the video standards of smartphones and TV and internet.

If wintel doesn't understand this video development, then digital cameras in smartphones can not follow the digital tV requirements for uploads.

Surviving with laptops of 800x600 displays?

Older laptop had small screens and can not use 1024x768 resolution because the screen does not have enough pixels. You have higher resolution but only shows a small portion on your small screen. Very annoying.

So, stay with 800x600 or even better 640x480?

Re: Display technology; resolution/zoomed data compression; DTV/hdmi ?

some one suggested using zoom on firefox view to reduce the sixe of the display on low resolution screen?

Have you tried it?

Re: Display technology; resolution/zoomed data compression; DTV/hdmi ?

Yahoo is getting webpages to 1024x600 so that 800x600 is no longer supported.

Display problems are acute for low resolution screen laptops such as dell CPi.

Facebook pictures on lcd display are lighter not as dark as picture tube brightness and contrast settings can do.


for smart phone picture taking, facebook pictures can be more usable on lcd display.

Re: Display technology; resolution/zoomed data compression; DTV/hdmi ?

To speed up video transfer on wifi, the new codes used are mpeg4(mjpg+MP3). it is 50% more efficient than mpeg2 or .ts files. mjpg can change resolution after you receive the low resolution codes.

This was developed in 2007 for digital TV conversion from analog TV of mpeg2. It increased DTV channels(6, often only 4) that can be crowded into each single carrier frequency.

This is now being done on cable service for video data efficiency. Resolution of the video frame can be compressed then expanded at will.

Re: Display technology; resolution/zoomed data compression; DTV/hdmi ?

Cable TV will be transfering video data by mpeg4(mjpg+MP#) instead of mpeg2 soon. This will improve resolution compression and allow more webpages to be transmitted on the internet, at the same time.

Mjpeg can change resolution after you received the data for super large lcd display. Its been tested on DTV broadcasting in the US since 2007. The technology is proven to be usable.

Now its going wifi for intrenet mulyistreaming packet frames?

Its already used by RCN cable modem?
