Recommendation for the generation of SAV/EAV (Start of
Active Video/End of Active Video) timing codes in the
bitstream. The SAV/EAV timing codes determine the
vertical blanking interval and the location of the active
display area.
Linear PCM
See PCM. A linear PCM encoder codes analog samples
on a straight-line basis, for example, sample amplitude 1
is coded as a binary 1, 2 as a binary 2, 3 as a binary 3,
etc. In A/V systems, Linear PCM refers to audio that has
been encoded in this manner. Non-linear PCM encoders
are used in systems such as telephone carrier systems
to reduce low-level noise.
Least Significant Bit/Byte
The bit or byte in a larger binary element, such as a
word, that has the smallest value.
Luminance
Brightness of an image (Y portion of a YUV signal or a
YCbCr signal). See YUV and YCbCr.
Motion Picture Expert Group
An IEEE (Institute of Electrical and Electronic Engineers)
committee that sets standards for compression and
format of motion picture (video) bitstreams and
accompanying audio information.
Most Significant Bit/Byte
The bit or byte in a larger binary element, such as a
word, that has the largest value.
