Videon now offers the ability to disable KLV MISB 0601 timestamps on the output as of software version V10.4.0! This feature addresses scenarios where timestamps may conflict with other metadata signals in the output stream, providing greater flexibility for your workflows.
Why Disable KLV Timestamps?
KLV metadata streams typically include MISB 0601 timestamps, which serve as precision time markers for synchronized metadata. While useful in many cases, some workflows require output streams without these timestamps to avoid interference with other metadata systems.
How It Works
A new feature is available to disable KLV timestamps in the output stream using REST API. Once enabled, the encoder stops inserting MISB 0601 timestamps while maintaining other KLV metadata as configured.
Steps to Configure
-
Open your API Client
(Postman is recommended, but feel free to use other API clients if you prefer.) -
Set an API with “GET” and add your device’s corresponding HTTP request
HTTP should follow the template:http :// DeviceIP : Port / APIversion(v2/v3) / encoders / data_encoder
Click “Send“.
-
Get data_encoder_id in body output
You should see a text as body output. For example, the data_encoder_id here is 147 (line 4). Remember your data_encoder_id. -
Add “\data_encoder_id“ to your API HTTP. Click “Send“.
You should get a new body output in similar format as the example below. -
Copy lines including “name“, “active“, “data_encoder_id“, “in_channel_id“, and “codec“.
In the example above, it would be everything from line 1 to line 11 except the extra comma at the end. -
Click ““Body”, select “JSON“ in the blue drop-down, then select “raw“, and paste the code into the text box. Add a “}“ at the end. Change “disable_misb1402_timestamps“ from false to true. Hit “Send“.
To verify if the change is effective:
- Stream the output to your playback tool or decoder (e.g., VLC).
- Use a KLV parser to confirm the absence of MISB 0601 timestamps in the metadata stream.
