QVidium™ MPEG2+4 Codec
Codec Configuration and Operation
The QVidium MPEG2+4 Codec can simultaneously encoder and decode two video over IP
streams, each one traveling in opposite directions over the same IP network. We call this mode of
operation “Codec” operation, in contrast to “Encode” or “Decode” operation. These two video
streams are completely independent of each other. However, a video encoding input signal must
be present before the codec can begin decoding and displaying an incoming stream.
In this Codec mode of operation, the codec encodes the video input signal using the stored
Encode Profile. The codec decodes the incoming IP video stream using the stored Decode Profile.
Clicking on “Start” under the Codec menu on the left side of the web page starts Codec operation.
“Stop” halts it. A “Status” menu item allows you to view the current status of both the encoding and
decoding on the same statistics page when started in codec mode.
Normally, when switching between the Encode and Decode modes of operation, the codec
currently requires that you power cycle the system. However, you can switch between starting the
Codec and the Encode modes of operation without power cycling.
