System Overview
NewsBrowse is a media management and editing system. When integrated with a
Profile XP Media Server and a NewsEdit system, NewsBrowse supports the complete
newsroom workflow — from ingest to editing to distribution to archive.

Functional description
NewsBrowse processes an incoming feed and simultaneously encodes it into two
formats: a low-resolution (MPEG-1) format stored locally on the Network Attached
Storage (NAS) unit, and a high-resolution format stored on the Profile Media Server.
NewsBrowse further processes the low-resolution files to create video thumbnails,
storyboards and RealVideo. You can use a web browser to edit stories using the
low-resolution media, which is accessible from the journalist’s desktop. NewsBrowse
also provides a rich metadata search engine that allows you to search for clips using
various criteria.
Once you complete a sequence with the NewsBrowse editor, NewsBrowse can use
that sequence to pull the corresponding high-resolution video from the Profile Media
Server and assemble an on-air quality sequence. NewsEdit can also use the sequence
in a similar way. NewsBrowse can also monitor the Profile Media Server to create
low-resolution files that do not exist, and stream live feeds.
From the NewsBrowse application you can archive and restore high-resolution media.
Archived media is still visible from the NewsBrowse application.
