Figure 3d: Decoder profile: “Server Tab”

Two other parameters, Video buffer size, specified in milliseconds, and Detect video break,

can help with the robustness of the decoder in handling packet loss and network interruptions.

We generally recommend setting the Video buffer size to between 300 and 500 ms. For low-

latency applications, you can try setting it as low as 150 ms. For maximum robustness, you

can increase this parameter to 1000 ms. We also recommend enabling Detect video break

and setting the Detect video break limit to 150 ms. When the decoder detects a pause or

interruption in the flow of incoming packets of this value or higher, the Detect video break

feature will automatically restart the decoder to help prevent it from getting into a bad state.

This can help if you are experiencing color loss or other decoder problems.

The ARQ tab, shown in Figure 3c above, configures the parameters for Automatic

Retransmission Request (ARQ) Error Correction. These parameters are explained in Appendix

B. The last panel, the Server tab, enables you to pull in a stream from a QVidium video server.

For more details on these features, please consult Appendix B. You should set the Use Server

to No (the default) when not using a QVidium server and in general when receiving a stream

from an encoder.

5. Press the Save button to save your changes. If you don‟t click Save, then your changes will be

ignored.

2. Click on the Start button.

3. When a valid video over IP stream is being received and decoded, the Video Status page will
