Glossary
THX
THX is a trade name of a high-fidelity sound reproduction standard for movie theaters, screening rooms,
home theaters, computer speakers, gaming consoles, and car audio systems. THX stands for T omlinson
H olman's e X periment .
The THX system is not a recording technology, and it does not specify a sound recording format: all
sound formats, whether digital (Dolby Digital, SDDS) or analog (Dolby Stereo, Ultra-Stereo), can be
"shown in THX." THX is mainly a quality assurance system.
THX-certified theaters provide a high-quality, predictable playback environment to ensure that any film
soundtrack mixed in THX will sound as near as possible to the intentions of the mixing engineer.
AVCHD
A
dvanced V ideo C odec H igh D efinition is a high-definition and standard-definition recording format for
use in digital tape-less camcorders and digital cameras. It is based on the H.264/MPEG-4 AVC video
compression standard. Audio is stored in compressed form (Dolby AC-3). The container format for the
audio and video is MPEG transport stream.
H.264
H.264 is a standard for video compression, and is equivalent to MPEG-4 Part 10 , or MPEG-4 AVC (for
Advanced Video Coding ). As of 2008, it is the latest block-oriented motion-compensation-based codec
standard. The final drafting work on the first version of the standard was completed in May 2003.
The intent of the H.264/AVC project was to create a standard capable of providing good video quality at
substantially lower bit rates than previous standards (e.g. half or less the bit rate of MPEG-2, H.263, or
MPEG-4 Part 2), without increasing the complexity of design so much that it would be impractical or
excessively expensive to implement.
YUV
YUV is used for a specific analog encoding of color information in television systems
Y' stands for the luma component (the brightness) and U and V are the chrominance (color) components.
