PLUTO TV LIVE STREAMING TECHNICAL REQUIREMENTS V2.2
Pluto TV Live Streaming Technical Requirements v2.2
All streams must be tested and integrated before they may be added to the Pluto TV platform.
The specification included in this document is not intended to provide partners with an exhaustive list of potential integration paths, rather to provide an example of what a preferred profile should look like. Nonconforming streams may require additional work to integrate and may increase the time it takes to onboard a stream.
Please submit stream information at least 4 weeks prior to launch or a live event to ensure there is sufficient time to validate across all platforms and ample time to address any issues with latency, performance, or playback quality.
