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 Tomlinson
Holman's eXperiment.
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

Advanced Video Codec High Definition 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.
