The Nexio® Digital Turnaround Processor™ (DTP) line represents the latest generation in the Imagine Communications compressed domain processing family of products, leveraging years of development and on-air experience.
The DTP aims to help broadcasters avoid decoding and re-encoding emission-level programs, thereby saving capital and operational costs, while still allowing the broadcaster to offer locally relevant content and services. An all compressed-domain approach optimizes video quality by preserving original encoder decisions as much as possible, while meeting the local station’s unique operating environment and business demands.
Now, in addition to grooming (add/dropping), splicing/switching and statistically multiplexing individual programs within single- or multiple-program transport streams, broadcasters can offer the following localization services through deployment of the DTP.
Processing MPEG-2 Programs
Frame-accurate ‘ad-insertion’ and program playback within network feeds
Local station branding through logo overlays
Local emergency alert systems (EAS), including text crawls and audio switchovers, to comply with government regulations and to provide better local community service
Trans-rate programs from different origination points into a compliant multi-program output
Community outreach with localized message crawls (e.g., weather and news alerts, etc.)
Overlay advertising - via animated graphics - on program video or national ads to burn in localized messages. This allows local ad revenue generation without the cost of full audio/video ad spot creation.
MPEG-2 Logo Overlay, Including Motion Logos Station identity is crucial to business success, especially for services provided for local area merchants and community organizations. To help grab the viewer’s attention, motion logos and custom text crawls can now be keyed into MPEG-2 video along with static logos.
MPEG-2 Frame Accurate Splicing Whether it’s advertisements or locally produced content, and whether inputs are real time or from compressed stream servers, the DTP will cleanly and frame-accurately switch various inputs to designated programs in the output transport stream, using our real-time frame transcode engine. The DTP will make a transcoded exit point in the current stream, frame-accurately inserting short or long-form program(s) into the output. When returning to network an entry point will be made to return at the exact time.
Generic MPEG- and ATSC-Compliant Multiplexer In addition to video/audio processing, the DTP fulfills the role of an emission-compliant re-multiplexer by managing bandwidth to fit the MPEG and ATSC-mandated transport stream broadcast rates to the home.The DTP multiplexes in-program and system information protocol (PSIP) data to comply with ATSC requirements.
PSIP PSIP can be emitted off of static settings and dynamic data from a network MPEG-2 transport stream or via reception from an external PSIP generator provided by best-in-class partner vendors.
Broadcast-Optimized Control The DTP was developed from the start with broadcast operations in mind. The DTP offers a simple, but robust API for automation control of branding, switching and ad insertion.
Upgradeable Software Architecture Broadcasters continue to evolve the DTV business model and launch unique new services.
