iSuppli, the outfit that makes it a habit of tearing down products as soon as they're released and splaying out their components for all to see, has already done an analysis of what it will cost Apple to build the $500 base model iPad. Not surprisingly, the number comes in at a good 50 percent less than the sales price--and it gets even better (for Apple anyway) as you move to the 32GB and 64GB models and add the 3G wireless component.
Remember, of course, this is only an estimate of hardware and manufacturing costs and doesn't factor in software, licensing fees, and a rather large promotional budget. That said, if you've ever wondered why Apple doesn't offer memory expansion slots for any of its products, the chart below gives you a pretty good reason why.
Though none of these numbers are confirmed, memory prices are memory prices, and paying $100 extra for something that cost Apple around $30 more (when you go from the 16GB to the 32GB model), is a tidy profit. The sad part is that most savvy consumers know they're getting ripped for adding that extra memory, yet we still do it (yes, I bought a 32GB iPhone).

Characteristics Of Video Streams
[starttext]
Frame Rate
- Frame Rate is the number of still pictures per unit of time of video, ranges from six or eight frames per second (frame/s) for old mechanical cameras to 120 or more frames per second for new professional cameras.
PAL (Europe, Asia, Australia, etc.) and SECAM (France, Russia, parts of Africa etc.) standards specify 25 frame/s, while NTSC (USA, Canada, Japan, etc.) specifies 29.97 frame/s.
Film is shot at the slower frame rate of 24photograms/s, which complicates slightly the process of transferring a cinematic motion picture to video. The minimum frame rate to achieve the illusion of a moving image is about fifteen frames per second.
Quality Of A Video
- Video quality can be measured with formal metrics like PSNR or with subjective video quality using expert observation. Subjective video quality methods are described in the ITU-T recommendation BT.500.
One of the standardized method is the Double Stimulus Impairment Scale (DSIS). In DSIS, each expert views an unimpaired reference video followed by an impaired version of the same video.
Interlacing
- Interlacing was invented as a way to achieve good visual quality within the limitations of a narrow bandwidth. The horizontal scan lines of each interlaced frame are numbered consecutively and partitioned into two fields: the odd field (upper field) consisting of the odd-numbered lines and the even field (lower field) consisting of the even-numbered lines.
NTSC, PAL and SECAM are interlaced formats. Abbreviated video resolution specifications often include an i to indicate interlacing. For example, PAL video format is often specified as 576i50, where 576 indicates the vertical line resolution, i indicates interlacing, and 50 indicates 50 fields (half-frames) per second.
Display Resolution
- Pixels is the unit of measure of a video image for digital video or horizontal scan lines and vertical lines of resolution for analog video. In the digital domain (e.g. DVD) standard-definition television (SDTV) is specified as 720/704/640×480i60 for NTSC and 768/720×576i50 for PAL or SECAM resolution.
The number of visible scanlines remains constant (486 NTSC/576 PAL) while the horizontal measurement varies with the quality of the signal: approximately 320 pixels per scanline for VCR quality, 400 pixels for TV broadcasts, and 720 pixels for DVD sources in the analog domain. Aspect ratio is preserved because of non-square "pixels".
Capable of resolutions up to 1920×1080p60, for example, 1920 pixels per scan line by 1080 scan lines, progressive, at 60 frames per second are new hig-definition televisions (HDTV). Video resolution for 3D-video is measured in voxels (volume picture element, representing a value in three dimensional space). For example 512×512×512 voxels resolution, now used for simple 3D-video, can be displayed even on some PDAs.
- The of information content in a video stream is measured by Bit Rate. It is quantified using the bit per second (bit/s or bps) unit or Megabits per second (Mbit/s). A higher bit rate allows better video quality.
Aspect Ratio
- The dimensions of video screens and video picture elements are described by Aspect Ratio. Most of all the popular video formats are rectilinear, and so can be described by a ratio between width and height.
The screen aspect ratio of a traditional television screen is 4:3, or about 1.33:1. High definition televisions use an aspect ratio of 16:9, or about 1.78:1. The aspect ratio of a full 35 mm film frame with soundtrack is 1.375:1. This is also known as the Academy ratio.
Ratios where the height is taller than the width are uncommon in general everyday use, but do have application in computer systems where the screen may be better suited for a vertical layout.
On computer monitors, Pixels are usually square, but pixels used in digital video often have non-square aspect ratios, such as those used in the PAL and NTSC variants of the CCIR 601 digital video standard, and the corresponding anamorphic widescreen formats.
Therefore, an NTSC DV image which is 720 pixels by 480 pixels is displayed with the aspect ratio of 4:3 which is the traditional television standard, if the pixels are thin and displayed with the aspect ratio of 16:9 (which is the anamorphic widescreen format) if the pixels are fat.
Bits per Pixel and Color Space
- The number of distinct colours that can be represented by a pixel depends on the number of bits per pixel (bpp). The video color representation is described by a Color Model Name. A common way to reduce the number of bits per pixel in digital video is by chroma sub-sampling. YIQ was used in NTSC television. It corresponds closely to the YUV scheme used in NTSC and PAL television and the YDbDr scheme used by SECAM television.
Digital Video Compression Method
- Video data contains spatial and temporal redundancy, making uncompressed video streams extremely inefficient. Broadly speaking, spatial redundancy is reduced by registering differences between parts of a single frame; this task is known as intraframe compression and is closely related to image compression. Likewise, temporal redundancy can be reduced by registering differences between frames; this task is known as interframe compression, including motion compensation and other techniques. The most common modern standards are MPEG-2, used for DVD and satellite television, and MPEG-4, used for home video.

System Types Of Analog Video Standards Worldwide
[starttext]Worldwide Analog Video Standards
NTSC (National Television System Committee)
- The analog TV system used in most of the Americas, Japan, South Korea, Taiwan, Burma, and some Pacific island nations and territories. It is also the name of the U.S. standardization body that developed the broadcast standard.
PAL (Phase Alternating Line)
- PAL or Phase Alternating Line is an analogue TV encoding system used in broadcast TV systems in large parts of the world.
SECAM (Sequential Color with Memory) / SÉCAM (Séquentiel Couleur à Mémoire)
- SECAM or Sequential Color with Memory is an analog color TV system first used in France. It is also a compatible standard, which means that monochrome television receivers predating its introduction are still able to show the programs.
Because of SECAMs compatibility requirement, color standards add a second signal to the basic monochrome signal, and this signal carries the color information, called chrominance or C in short, while the black and white information is called the luminance or Y in short.

An Introduction To Video - It's History and Evolution
[starttext]
The concept of video was taken from it's rather smaller type of media class, the images or photos. People frequently use this type of media especially when there are occasions, happenings or events. It's usefulness has quite facinated a lot of people not only here but also in different countries.
Videos burst online unto the scene and spreading like wildfire. The typical viewer today spends 158 minutes per month watching videos online. The viewership sums up to 14 billion videos a month. By 2013, it is predicted that 90% of all online content will be in the form of video. Uses of Fiber optic cable will increase so much then eventually the internet, cable TV Channels and broadcast TVs will all merge into one.
An interactive videos can link to any other site on the web. It can integrate interesting sidebars without dragging the show out to an interminable length. It is one of the benefits of interactivity for the viewer.
Interactive videos is one of the most promising of technologies to come along in a while, and in this day of technological wizardry like Laparoscopic Eye Surgery or GPS mounted on your dashboard, that's saying a lot.
On a technical level, interactivity is achieved by superimposing a flash overlay on top of the video file. The flash overlay remains a separate digital entity, but appears to the viewer to be part of the picture.
YouTube's interactivity is referred to as "annotations", and right now is rather limited in scope. Other online video platforms offer interactivity too. Many of them use it for kicks right now (One service is even called KICK) but some of the more business-minded companies are developing video activity for commercial use.
History Of Video Technology
The word "video" was taken from the latin verb "videre" that means "I see". Cathode Ray Tube Television Systems were the first one to apply Video Technology. Their are several new technologies for video display devices were invented after it's creation.
The introduction of VHS (and Beta-Max, which VHS predecessor) home recording of television programs became a reality. But before long, the cassette recorder become a source of inconvenience as well as a blessing, as families were left arguing over which show should be taped, and only a few hours of footage could be recorded onto one cassette.
With the creation of Television sets (TV) and Computer Monitors, both of it's standards have evolved independently but the their evolution and advances produced some intersection. Convergence of the two can be seen today. For example, Computers can now display television and film-style video clips and streaming media, encouraged by increased processor speed, storage capacity, and broadband access to the Internet.
The onset of DVD (Digital Versatile Disk) was the next leap forward in home video technology. These were a quantum leap ahead compare to VHS. Of course, I am forgot to mention the notorious Laser Discs, which were incredibly large discs that had to be flipped half-way through the film, and were the first technology to introduce special features such as director's commentary and deleted scenes. Laser Discs would have become far more popular. As it was, they were strictly the possessions of film fans and rich folks looking for something to spend their disposable income on.
In almost every way we can imagine, technology has moved forward into increasingly complex directions. A number of decades ago it was considered impossible to have any kind of recordable video, the introduction of VHS tapes put an end to this, and soon DVD's were stocking the shelves of electronic stores everywhere. Now Blu-Ray has entered the scene with ever-higher levels of quality and convenience.
Now we have the new technology of Blu-Ray and HDTV. While the images this technology is capable of producing is incredible, the excitement from customers is nowhere near that of DVD. Perhaps we have grown weary of this constant advancement, and many are reluctant to have to replace their entire DVD collection with a new technology.
The main problem with the emphasis on technical aspects is that the most important thing about a movie is the actual content of the movie itself, not the level of quality we see it in.
Video Technology will sure continue to improve as long as there are people around the globe who are using it and wants more from it.
