Unified Remix ‘mixes’ media from various origin into a single stream. Clients and playback devices see the stream coming from a single origin and having a timeline without any discontinuities.
Remix uses a playlist, in SMIL format, as its single input format. It transforms this SMIL file into a reference MP4 (ISOBMFF) for Unified Origin to use.
Since Unified Origin delivers all playout formats from this remixed MP4, we now have a unified approach to deliver to all devices from a single SMIL playlist!
Resolving a playlist server side has the following benefits:
- It works everywhere, on all devices, as they see only one stream.
- No player development is required, so larger audience can be reached as it ‘just works’.
- Flexibility. Changes can be made server side, without having to update devices or apps.
- Ad blockers are circumvented.
Streams can be personalized on any level. From a personalized stream for every viewer, streams to groups of viewers (e.g. based on geolocation, subscription model), and even a single stream for all viewers.
