Bitstream
The digital form of
Decoder
A decoder restores coded audio signals on DVDs to normal.
Dolby Digital
This is a method of coding digital signals developed by Dolby Laboratories. Apart from stereo
Dolby Pro Logic
A surround system where a
2 channels and then is restored to 4 channels for play. The surround channel is monaural and can reproduce up to 7 kHz.
DTS (Digital Theater Systems)
This surround system is used in many movie theaters around the world. There is good separation between the channels, so realistic sound effects are possible.
Dynamic range
Dynamic range is the difference between the lowest level of sound that can be heard above the noise of the equipment and the highest level of sound before distortion occurs.
Film and video
Frame still and field still
Frames are the still pictures that make moving pictures. About thirty are shown each second. A frame still may appear blurred but overall quality is high.
Two fields appear alternately to make up one frame. A field still is not blurred but picture quality is lower.
Interlace and progressive output
NTSC, the video signal standard, has 480 interlaced (I) scan lines, whereas progressive scanning uses twice the number of scan lines. This is called 480P.
I/P/B
MPEG 2, the video compression standard adopted for use with DVD- Video, codes frames using these 3 picture types.
I: Intra coded picture
This picture has the best quality and is the best to use when adjusting the picture.
P: Predictive coded picture
This picture is calculated based on past I or
This picture is calculated by comparing past and future I and
Linear PCM (pulse code modulation)
These are uncompressed digital signals, similar to those found on CDs.
