Encoding
About video/audio encoding
Since today’
s technology does not permit the economical streaming or capturing (to solid-state memory) of wideband digital vide
o
signals, it is necessary to compress the video and audio signals for these applications.
Encoding is the process of compressing the original signal into a signal small enough to be useful for these applications.
The
SA-
DV6000 uses ISO MPEG-4, revision 1.04, the most widely accepted variant of the MPEG-4 algorithm, supported by industry leaders,
such as Microsoft.
The audio encoder uses the ITU-T
G.726 algorithm (for W
indows Media Player mode) and
µ
law algorithm (for Quick
T
ime mode).
With MPEG-4 video, the bit rate (amount of data per second), frame rate (number of frames per second) and the image size can be
changed as necessary
.
However
, these parameters directly influence the picture quality
. When lowering the bit rate, for example, the picture quality
will de-
crease but will have lesser load on the network and longer recording is also possible.
When lowering the frame rate, smooth video playback will be suf
fered but the picture quality will increase since the larger dat
a volume
per frame.
The same ef
fect can also be observed when reducing the image size.
The selected encoding parameters af
fect both the streaming capabilities and the amount of video that can be stored on a CF memo
ry
card, but does not af
fect the VTR’
s outputs or the video recorded to tape. Please refer to the table on Page 8 for the encoding
values
supported by the SA-DV6000.
Note
The selected encoding parameters are independent of, and do not af
fect the DV recording or VTR’
s outputs.
