DTP-301
Digital Turnaround Processor™ (DTP™)
The Digital Turnaround Processor™ (DTP™) line represents the latest generation in the Harris compressed domain processing family of broadcast 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:
ON MPEG-2 Programs
- 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
- Splicing to allow local promos and advertisements within network feeds
- 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
- Community outreach with localized message crawls (e.g., weather and news alerts, etc.)
Features
- Seamless splicing for H.264/AVC SD or HD programs
- Frame accurate splicing of MPEG-2 SD or HD programs
- Complete MPEG-2 stream processing for all 4:2:0 color space, emission-compliant formats including 720p, 1080i and 1080p format HD
- Still logos through multiformat image files where the alpha channel determines transparency
- Animated graphics and logos through frame-by-frame multiformat image sequences
- Pixel-perfect graphic object positioning and user-specified dissolve rates
- Character generation text crawls for messaging and emergency alert system applications
- Digital Program Insertion utilizing DPI control from network and program, or commercial clips stored internally or on network attached storage
- Support for industry-standard automation protocols, and pre-integrated with on-air automation system vendors
- Remux functions:
Such as PSIP multiplexing and rate control/re-statistical multiplexing to generate an ATSC-compliant transport stream
Product Details
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.
With no decoding and re-encoding required, the DTP allows logos at various transparency settings to be dissolved on and off of HD and SD signals. With standard graphics tools, objects and logos can be created quickly and easily by creative staff or engineers. The DTP allows the use of off-the-shelf animation programs to create motion logos out of image file animation sequences. Additionally, users can store a virtually unlimited number of logos and graphics on DTP local storage, or on external network servers via Ethernet.
H.264 and MPEG-2 Seamless 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 seamlessly switch various inputs to designated programs in the output transport stream. Switches can also happen one at a time, or with multiple programs (all SD, or a combination of HD and SD) being switched at the same time.
Generic MPEG- and ATSC-Compliant Remux
In addition to video/audio processing, the DTP fulfills the role of an emission-compliant remultiplexer by managing bandwidth to fit the DVB- 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. The DTP can be controlled by presets paired with GPI triggers and/or SCTE-35 in-band commands paired with downloadable playlists.
Upgradeable Software Architecture
Broadcasters continue to evolve the DTV business model and launch unique new services. To keep pace with this ever-changing industry, broadcast products need to bring new features to market quickly, with upgrades being as nonintrusive on daily operations as possible. The DTP is a broadcast-quality, real-time operating system and general-purpose computing platform with patented software for real-time compressed video processing. This flexible architecture allows the unique Harris algorithms to be continuously enhanced to improve performance and to roll out new features quickly and efficiently — in most cases by performing software-only updates in the field.
