Chapter 1 System Overview

The MediaFrame system

The following diagram illustrates the MediaFrame system.

Functional description

Aurora Browse allows desktop browsing of low-resolution proxy copies of both SD
and HD high-resolution video material. Aurora Browse provides a rich metadata
search engine that allows you to search for clips using various criteria. You can also
use the Aurora Browse application to trim assets, add keywords, create subclips, etc.,
using a low-res proxy accessible from your PC. From the Aurora Browse application
you can also archive and restore high-resolution material.

The system is compatible with the K2 storage system. Ingest is controlled by an ingest
application, such as Aurora Ingest, and incorporates the K2 system as the video
server. The incoming feed will be generated into two formats: a proxy low-res
(MPEG-1) format stored on the proxy NAS, and a high-resolution format stored on
the storage system. Aurora Browse also monitors the storage to create proxy for new
high-resolution material. In this way Aurora Edit assets are represented in the system
for editing and manipulation.
