Unified Remix¶

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.
