Low latency content delivery is crucial for some TV channels, especially for live sporting events.
We have implemented support of CMAF low-latency in our products, which is based on splitting long MP4 segments into shorter chunks and immediately transmitting them to end-user devices for playback.
To deliver good results, this technology is supported by all components on the content delivery path from the head-end to the end-user device.
The feature is available on the commercially available SmartMEDIA 8.2 and SmartTUBE Ultra application for Android TV. We will continue working on low latency support for our other client applications.
The feature supports multi-bitrate streaming, Widevine DRM content protection and does not require any additional hardware.
Our tests show that the delay from real time can be less than 4 seconds.
In SmartMEDIA 8.3, we optimized interaction between the SmartMEDIA server and transcoders, reducing the required HW resources for a live transcoding farm.
In SmartCARE 8.3, we added new metrics to analyze all stages of the playback startup process, including downloading a playlist, first chunks, DRM licenses, etc. to help find bottlenecks in the content delivery pipeline.
All metrics are now collected from client devices, not only from SmartMEDIA servers, as it was implemented earlier. This approach allows us to collect more data and support 3rd-party streaming servers and services. The improved SmartCARE session analysis dashboard offers a more efficient worm-eye data presentation.
