"1080p is the shorthand name for a category of HDTV video modes. The number "1080" represents 1,080 lines of vertical resolution (1080 horizontal scan lines), [1] while the letter p stands for progressive scan (meaning the image is not interlaced ). 1080p can be referred to as full HD or full high definition to differentiate it from other HDTV video modes. [2] The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels. This creates a frame resolution of 1920�1080, or 2,073,600 pixels in total. The frame rate in hertz can be either implied by the context or specified after the letter p (or i), such as 1080p30 , meaning 30 Hz. [3]
1080p is sometimes referred to in marketing materials as "Complete High-Definition". However, 2K/4K digital cinema technology is commercially available, and ultra-high definition video is in the research phase.
In addition to the meaning of 1080p as a display resolution, 1080p is also used to describe video equipment capabilities. Use of 1080p and the closely related 1080i labels in consumer products may refer to a range of capabilities. For example, video equipment that upscales to 1080p takes lower resolution material and reformats it for a higher resolution display. The image that results is different from the display of original 1080p source material on a native 1080p capable-display. Similarly, equipment capable of displaying both 720p and 1080i may in fact not have the capability to display 1080p or 1080i material at full resolution. It is common for this material to be downscaled to the native capability of the equipment. The term "native 1080p-capable" is sometimes used to refer to equipment capable of rendering 1080p fully."

"HD Ready vs Full HD TV , size does matters
For the same screen size, Full HD cost much more than Ready HDTVs. If you are on a budget, buying a HD Ready set instead of a Full HD set will save you quite a substantial amount of money.
As a general guideline, if you are getting a HDTV set which is less than 42 inch, you won't be able to notice the resolution difference between a Ready set vs a Full HD set. Thus, you will be able to get almost the same visual enjoyment at a lower budget if you buy a HD Ready HDTV (720p) instead.
For screen size 42 inch or greater, going for a Full HD (1080p) will be a better choice as at such big screen size, the pixel difference will be more visible." www.squidoo.com ( hd review).
Did you know " The human eye's detection system in the retina consists primarily of two types of light detectors, rod cells that capture light and dark, and the cone cells that detect color. A typical retina contains 120 million rods and 4.5 to 6 million cones, which are divided among three groups that are sensitive to red, green and blue light. This means that the eye has far more resolution in contrast, or " luminance ", than in color. However, post-processing in the optic nerve and other portions of the human visual system combine the information from the rods and cones to re-create what appears to be a high-resolution color image.
The eye has limited bandwidth to the rest of the visual system, estimated at just under 8 Mbit/s. This manifests itself in a number of ways, but the most important in terms of producing moving images is the way that a series of still images displayed in quick succession will appear to be continuous smooth motion. This illusion starts to work at about 16 fps , and common motion pictures use 24 fps. Television, using power from the electrical grid , tunes its rate in order to avoid interference with the alternating current being supplied – in North America this is 60 fields a second to match the 60 Hz power, while in Europe it is 50 fps to match the 50 Hz power.

"HD PVR update positively received
Tom Manners MyBroadband | 11 May, 2009
HD PVR Software update seems to have resolved many problems, but may cause reboot problems
Since the release of Multichoice's HD PVR update last week the reports from users have been generally positive.
"Just did the upgrade. All I can say is what someone else said in another thread. Feels more responsive and the news and weather is available in the interactive menu," said the forum user Quantum Theory.
"Installed on my HD PVR - must say I am pleased with the EPG response now - can view programs 8 days in advance as its supposed to have been - will definitely make more use of the scheduled recordings now," forum user Adsl3g said,
The software update is currently available via a voluntary download and, according to Multichoice, a forced update for all HD PVR users will be instituted towards the end of this week if every goes well.
The update, among other factors, has improved recording reliability, loading times for TV guide data, response times when changing channels and has added interactive News 24 and Weather 24 channels.
Despite the general positive reception, some users have complained that their decoders are rebooting continuously after downloading the update. A Multichoice representative on the DSTv forum has provided a solution involving the removal of all four LNB tuners connected to the device and a specific reboot method.

What is HDMI
"HDMI ( High-Definition Multimedia Interface ) is a compact audio/video interface for transmitting uncompressed digital data. It represents a digital alternative to consumer analog standards such as Radio Frequency (RF) coaxial cable , composite video , S-Video , SCART , component video , D-Terminal , and VGA . HDMI connects digital audio/video sources such as set-top boxes , Blu-ray Disc players, personal computers (PCs), video game consoles (such as the PlayStation 3 and Xbox 360 ), and AV receivers to compatible digital audio devices, computer monitors , and digital televisions . [ 1 ]
HDMI supports, on a single cable, any TV or PC video format, including standard, enhanced, and high-definition video , up to 8 channels of digital audio, and a Consumer Electronics Control (CEC) connection. The CEC allows HDMI devices to control each other when necessary, and allows the user to operate multiple devices with one remote control handset. Because HDMI is electrically compatible with the signals used by Digital Visual Interface (DVI), no signal conversion needs to take place nor is there a loss of video quality when a DVI to HDMI adapter is used. As an uncompressed connection, HDMI is independent of the various digital television standards used by individual devices such as ATSC and DVB as these are encapsulations of compressed MPEG video streams (which can be decoded and output as an uncompressed video stream on HDMI).

Best experienced with blu ray on home theatre
Blu-ray Disc (also known as Blu-ray or BD, blue ray disc) is an optical disc storage medium designed by Sony to supersede the standard DVD format. Its main uses are for running Playstation 3 games, high-definition video and data storage with 50GB per disc. The disc has the same physical dimensions as standard DVDs and CDs .The name Blu-ray Disc derives from the blue laser used to read the disc." (Wikipedia.org)

"Home cinema , also called home theatre, are entertainment systems that seek to reproduce movie theatre quality video and audio in a private home. In the 1950s, home movies became popular in the United States with Kodak 8 mm film projector equipment becoming affordable. The development of multi-channel audio systems and laserdisc in the 1980s created a new paradigm for home cinema. In the early to mid 1990s, a typical home cinema would have a Laserdisc or S-VHS videocassette player fed to a large rear projection television. In the late 1990s, home theatre technology progressed with the development of DVD, Dolby Digital 5.1-channel audio ("surround sound"), and High-Definition Television.
More on Home theatre
In the 2000s, the term "home cinema" encompasses a range of systems. The most basic system could be a DVD player, a standard CRT television , and a " home theatre in a box ", a 2.1 speaker system with left and right speakers and a small 8" subwoofer cabinet. An expensive home cinema set-up might include a Blu-ray player, a 60" High-Definition Television with a "cinema-style" 16:9 format, a several thousand-watt home theatre receiver with five to seven surround sound speakers, and a powered subwoofer with a 12" (or more) driver. The most expensive home theatre set-ups, which can cost over $100,000 US, have digital projectors, expensive screens, and custom-built screening rooms which include cinema-style chairs and Audiophile -grade sound equipment.
