Blu-Ray

Blu-ray, also known as Blu-ray Disc (BD) is the name of a next-generation optical disc format. The format was developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data. The format offers more than five times the storage capacity of traditional DVDs and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc.

1080p

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), 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.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 giving the best possible picture available.

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.HDMI supports, on a single cable, any TV or PC video format, including standard, enhanced, and high-definition video and up to 8 channels of digital audio.

LCD

A liquid crystal display (LCD) is an electronic optical device shaped into a thin, flat panel made up of any number of color or monochrome pixels filled with liquid crystals and arrayed in front of a light source (backlight) or reflector. It is often utilized in television displays because it uses very small amounts of electric power.
Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes, and two polarizing filters.
In color LCDs each individual pixel is divided into three cells, or subpixels, which are colored red, green, and blue, respectively, by additional filters. Each subpixel can be controlled independently to yield thousands or millions of possible colors for each pixel.

Plasma

A plasma display panel (PDP) is a type of flat panel display common to large TV displays (32 inches or larger). Many tiny cells between two panels of glass hold an inert mixture of noble gases. The gas in the cells is electrically turned into a plasma which then excites phosphors to emit light. Plasma displays should not be confused with LCDs, another lightweight flatscreen display using different technology.

Plasma displays are bright (1000 lux or higher for the module), have a wide viewing angle, and can be produced in fairly large sizes, up to 381 cm (150 inches) diagonally. They have a very low-luminance "dark-room" black level compared to the lighter grey of the unilluminated parts of an LCD screen. The display panel is only about 6 cm (2.5 inches) thick, while the total thickness, including electronics, is less than 10 cm (4 inches).

LED-backlit LCD Television or LED TV (term used by Samsung Electronics, Toshiba, Philips, and LG Electronics)

LED TV is an LCD TV that uses LED backlighting. LED's are used for backlighting, instead of fluorescent lights. LED-backlit LCD TVs differ from conventional LCD TVs in some important areas: They can produce a very bright image with greater contrast and deeper blacks compared with LCD TVs.
With Edge-LED lighting they can be extremely slim. Current models on the market are just over 25mm thick. They consume much less power. About 40% less compared with an LCD TV of a similar size.

Digital TV Switchover

The digital TV switchover is Government policy. It will mean that almost everyone will be able to receive digital TV through an aerial (Freeview). Digital TV also uses less broadcast space which means that after switchover, there will be more room for new services such as wireless broadband, local TV and High Definition Television (HDTV). To keep your TV service, you will need to convert your TVs to digital before your area’s switchover date.
