Built-In Compression Module
Figure 5-75: Compression Module
iN7000 currently has one video/audio compression module for local storage and Internet broadcast. The
audio and video compression codecs are WMA Pro and WVC1 respectively(a VC-1 compliant codec,
which is a direct competitor to H.264.
You can find more information by searching the keyword ‘VC-1’ on http://www.wikipedia.org ) respect-
ively.
Check the Bind Module box to locally save or broadcast a channel.
- Storage and broadcast tabs : These 2 tabs have almost the same set of settings; one for local storage
and one for broadcast. They can run the same or different parameters. For example, you can configure
that only video samples with motion will be compressed and propagated to broadcast modules (such as
Video Server and Window Media Broadcast), while compression for local storage is round-the-clock.
In general, we recommend you to use the same settings for both storage and broadcast, as in the figure
below. If the settings for storage and broadcast are different, 2 compressors will be used, which is more
CPU-intensive.
