Nexio servers now support a software solution for audio track manipulation and closed caption file import and export. The Nexio Track Router product is ideal for users that broadcast content in different languages on different channels. It allows them to store a single video clip and add new audio and caption tracks during the workflow process and Nexio will take care of playing the correct language(s) on the correct channels.
Nexio Track Router provides an interface for dynamic control of audio track tagging (applying user-friendly names that uniquely identify each audio track in the clip essence), audio track addition (adding new audio tracks to an existing clip), audio track deletion, audio track shuffling, and audio track playout routing. These functions ensure the correct audio will come out of the desired channels. You can perform audio routing of up to 32 tracks on any clip stored on Nexio with mapping defined on either a per-clip or per-port basis.
Three primary applications for audio routing are targeted:
- Re-ordering, adding or deleting multiple language tracks for local broadcast requirements or across channels with different primary languages.
- Re-mapping of audio on distributed program content to suit local output requirements, such as moving AC-3 and stereo audio channels.
- Supporting different HD and SD audio profiles when up-converting or down-converting content.
Nexio Track Router supports the export of audio files, supporting workflows that require the addition of one or more dubbed secondary audio tracks or captions. The new audio or caption files can then be imported and merged with a Nexio clip for playback.
The Nexio Track Router user interface is accessible from Nexio NXOS, Nexio Remote, or Nexio FTP Client. It is activated by software license key. Nexio also supports audio track routing control by broadcast automation software via protocol commands in the Nexio API.
The Track Router application, model number NXA-TR, is an optional Media Application for Nexio AMP and Nexio Volt servers. It is enabled in the Nexio NXOS or Nexio Remote interface to control track manipulation, audio and caption file import and export. Audio and closed caption files are imported via Nexio FTP server. Nexio Track Router is enabled by a software license key. There is no need for hardware dongles.
