Bitstream
Submitted January 19, 2008 by doctorsteve
Bitstream: A specific way of transmitting information from one place to another. The Bitstream ‘style’ of data transmission sends “compressed” information (data that has been previously ‘packaged’, or squashed down to save space) to an audio receiver. That receiver must then de-compress (or “decode”) the data before it can be ‘read’ and played by the receiver as sound. See Compression.

Coffee Book
Submitted April 16, 2008 by Blimey!
A style of release for Blu-ray discs by Warner Bros. It resembles a hardcover book and contains a limited number of pages about the release but also acts as a storage box for Blu-ray disc(s). Also sometimes referred to as "Coffee Table Book Edition" and "Blu-ray/Coffee book".
Compression
Submitted January 19, 2008 by doctorsteve
Compression: Taking a large amount of information/data, and ‘re-writing’ it so that the new data takes up less space (on a Blu-ray or CD, for examples). This is known as “compressing” the data (or “encoding”). Before the data can be used again, it must be “decompressed” (or “decoded”). Some Blu-ray players can decompress data on their own – then send it to the receiver (as uncompressed PCM) to play it. Some must send the compressed data to an audio receiver first, and the audio receiver must then perform the decompression and play the audio. This depends on what compression method has been used, and if that player is capable of performing the decompression itself. Additionally, not all compression methods are equal. Some processes allow for exact copies of the original audio to be produced (Lossless), others do not produce exact copies of the original data and therefore some information is lost (Lossy). Some of the ‘styles’ of audio compression include: Dolby Digital, DTS, Dolby TrueHD, DTS-HD Master Audio (MA). See Bitstream. See PCM. See Lossy. See Lossless.

HDCP
Submitted May 9, 2007 by richiev4
High Definition Content Protection. The system used to ensure that content cannot be copied from one source to another. All devices (Player, TV etc) must support this else the High Definition signal will be downgraded to VHS Quality.
HDMI
Submitted December 30, 2006 by thunderhawk
HDMI or High-Definition Multimedia Interface is an all-digital audio/video interface capable of transmitting uncompressed streams. HDMI also incorporates Digital Rights Management technology. HDMI provides an interface between any compatible digital audio/video source, such as a set-top box, a DVD player, a PC, a video game system, or an AV receiver and a compatible digital audio and/or video monitor, such as a digital television (DTV).
It is a modern replacement for older analogue standards such as SCART or the RCA connector.
IAR
Submitted April 9, 2008 by abintra
Intended Aspect Ratio.
Where as OAR, original aspect ratio, can be used in various contexts meaning anything from the original camera negative aspect ratio, to how the material was originally shown (even if it was modified from its intended aspect ratio), to its most common application of its original (ie. intended) aspect ratio, intended aspect ratio (or IAR for abbreviation) is the preferred, most descriptive and accurate term to imply the intended aspect ratio by its creators.
Letterbox
Submitted October 30, 2007 by Rustmonsteru
When the original aspect ratio of a film does not match the aspect ratio of the display device it is viewed on/with resulting in “black bars” above and below the film. This maintains the film in an unaltered condition as it was intended to be seen.
Examples: Pirates of the Caribbean with a 2.35:1 aspect ratio will show up letterboxed on 4:3 and 16:9 ratio displays. Other films with a 1.85:1 aspect ratio such as Chicago or the BBC produced Planet Earth will fill a widescreen display entirely but will still be letterboxed on an older 4:3 televisions.
Lossless
Submitted January 19, 2008 by doctorsteve
Lossless: Refers to audio that has been reproduced from the original source (Blu-ray disc, CD, eg.) without having lost any information. Lost information results in a ‘less-than-perfect’ reproduction of the audio track. Uncompressed PCM, Dolby True HD, and DTS-HD MA are examples of lossless audio feeds. All Blu-ray players are capable of transmitting uncompressed PCM data to a receiver using an HDMI cable. Not all players are capable of decoding/transmitting every type of compressed data. See your player’s user manual for details. See Compression. For comparison, See Lossy.
Lossy
Submitted January 19, 2008 by doctorsteve
Lossy: Refers to audio that is not an exact reproduction of the original. During the recording/compression process, information has been lost, and may result in the perception of less quality/depth/richness of sound. Not all players are capable of decoding/transmitting every type of compressed data. See your player’s user manual for details. Examples of Lossy sound compression methods include DTS, Dolby Digital, and DTS-HD HR. See Compression. For comparison, See Lossless.

PCM
Submitted January 19, 2008 by doctorsteve
PCM: “Pulse Code Modulation”. A specific way of transmitting digital sound information from one place to another. The PCM ‘style’ of data transmission sends the info “uncompressed”. This means that when it is sent from the data source (a Blu-ray disc, CD, etc.) to a piece of audio equipment – it can be instantly ‘read’ and played. Compressed data has been previously ‘packaged’, or squashed down to save space on the disc. Compressed data must be Decompressed (or “decoded”) in order to be ‘read’ – like boxing up your book collection when you move, you must unpack your books before you can read them again. PCM is different. Since the data has not been ‘boxed up’, it does not have to be ‘unboxed’ (or “decoded”) before it is usable. See Compression.
Pillarbox
Submitted October 30, 2007 by Rustmonsteru
When the original aspect ratio of a film does not match the aspect ratio of the display device it is viewed on/with resulting in “black bars” or “pillars” on the sides of the film. This maintains the film as it was intended to be seen.
Examples: Old films with a 4:3 or 1.37:1 aspect ratio like Seven Samurai or The Wizard of Oz will be displayed this way on 16:9 ratio “widescreen” display devices.
Posterization
Submitted January 19, 2008 by rjg77vett
Occur when the color depth, sometimes called bit depth, is insufficient to accurately sample a continuous gradation of color tone. As a result, a continuous gradient appears as a series of discrete steps or bands of color — hence the name. When discussing fixed pixel displays, such as LCD and plasma televisions, this effect is also referred to as false contouring.

Windowbox
Submitted October 30, 2007 by Rustmonsteru
Simultaneous letterboxing and pillarboxing of a film resulting in “black bars” all the way around picture. This is most often the unintended result of viewing non-anamorphic letterboxed material on a widescreen display. Windowboxing is used intentionally sometimes to counter overscan on displays without overscan control so that no part of the
image is lost to the viewer; The result is a smaller picture with lowered resolution however.
