CPPM (Content Protection for Prerecorded Media)
A copy protection system used for DVD-Audio files. This unit supports CPPM.
Down-mixing
This is a process of remixing the multi-channel audio (surround sound) on some discs
into two channels. When you want to listen to the audio on a DVD with a 5.1 channel
digital surround track through your television speakers, the down-mixed audio will be
output.
Some DVD-Audio prevent down-mixing of all or part of their contents. When playing
such discs, or such parts of the disc, unless the number of connected speakers is the
same as the disc’s channel specification, audio will not be output properly.
Film and video
DVD-Videos are recorded using either film or video. This unit can determine which type
has been used, then uses the most suitable method of progressive output.
Film:
Recorded at 24 frames per second. (Recorded at 30 frames per second as well).
Generally appropriate for motion picture films.
Video: Recorded at 30 frames/60 fields per second. Generally appropriate for TV drama
programs or animation.
HDCD (High-Definition Compatible Digital)
HDCD-encoded CDs sound better because they are encoded with 20 bits, as compared
with 16 bits for all other CDs.
HDMI (High-Definition Multimedia Interface)
HDMI is a next-generation digital interface for consumer electronic products. Unlike
conventional connections, it transmits uncompressed digital video and audio signals on
a single cable. This unit supports high-definition video output (720p,1080i) from HDMI
AV OUT terminal. To enjoy high-definition video a high definition compatible television is
required.
MPEG4
A compression system for use on mobile devices or a network, that allows highly
efficient recording at a low bit rate.
Sampling frequency
Sampling is the process of converting the heights of sound wave (analog signal)
samples taken at set periods into digits (digital encoding). Sampling frequency is the
number of samples taken per second, so larger numbers mean more faithful
reproduction of the original sound.
