Introduction to ESB3022 - the ew-vodjit service

Managed Content

The Repackager (ESB3002) and the VoD-to-Linear (ESB3019) require VoD assets to be available in ESF format. Assets are normally ingested into ESF with ew-vodingest (ESB3021) or ew-recorder(ESB3005). The ESF format is an internal format for efficient streaming. Such ingested assets will be referred to as managed content.

However, in some cases, for example having a big catalogue of rarely watched content, it may be unsuitable to ingest and convert all content to ESF format, and it may be preferred to keep the content as “external content”.

ew-vodjit provides a solution by being able to read such “external content”, and convert it to ESF format on-the-fly. The ESF format is then not stored on disk, but only available via HTTP. For the repackager, the asset looks like a normal (managed) ESF asset, except that some operations like getting the first metadata may take longer time.
