NEXIO® PRX Transcoder

The NEXIO PRX Transcoder represents the latest in NEXIO server technology and is built on the powerful NEXIO NX1011 series 1RU platform. It reads high-resolution files from the NEXIO SAN in all NEXIO-supported SD and HD formats through its on-board, dual-port Fibre Channel adapter or via Gigabit Ethernet when using the Media Host architecture. The NEXIO PRX Transcoder performs a real-time transcode of four to eight independent, simultaneous streams and writes those proxy files to standard IT storage.

The NEXIO PRX Transcoder includes the PRX Scavenger software application, which communicates with both the high-resolution NEXIO SAN and the low-resolution storage system.

It is a synchronization application that automatically determines which high-resolution clips need to be transcoded, as well as the transcoder channel assignments, metadata updates and low-resolution clip deletion. Rules can be defined to control creation and deletion of low-resolution content. Under the control of PRX Scavenger, the PRX Transcoder application performs the actual transcode from high-resolution media to low-resolution global proxy file.

The H.264 MP4 proxy files generated by the NEXIO PRX Transcoder are available for browse viewing with any standard media player. Alternately, due to the unique implementation of the global proxy file format, the MP4 files created by the NEXIO PRX Transcoder can be viewed with the same metadata information that is saved with the high-resolution files on the NEXIO SAN, either in a Harris® PRXPlayer or through the NEXIO MediaBase plug-in.

The MP4 proxy files are also available for editing with Velocity PRX™ proxy editors (version 2.0 or higher). Projects edited with Velocity PRX using global proxy files can be conformed directly to high-resolution clips using the NEXIO InstantOnline III™ conforming engine or sent to Velocity ESX™ and/or Apple® Final Cut Pro® for high-resolution finishing. The NEXIO PRX Transcoder is also capable of creating low-resolution proxy files from clips that are currently being ingested by a NEXIO AMP® ingest channel, clips that are created by Velocity™ or Final Cut Pro® editors, clips that are created by InstantOnline III and clips that are being transferred into the NEXIO SAN via FTP or other import methods. Proxy creation begins shortly after a record or file creation is initiated.

NEXIO Global Proxy media can be used by NEXIO, Velocity and Invenio® digital asset management, as well as many other third-party applications, thus eliminating redundant proxy generation. The proxies are viewable in common players like QuickTime® or Windows Media Player® and can provide content to Apple® iPhone®, Blackberry and other mobile devices. In addition, they can be used to link multiple NEXIO server systems in different locations. Synchronization of multiple sites is maintained by Invenio Motion. This workflow allows local editors to choose and pull high-resolution content from any linked NEXIO system before editing, or edit the low-resolution proxy and use InstantOnline III to conform later. InstantOnline III is capable of instructing Invenio Motion to gather the high-resolution media required to conform the edit from remote locations, as well as from its assigned NEXIO shared storage system.
