MultiMerge DTV 5.1 Surround Audio Processor Encoder/Decoder with DTS Neural Loudness Control.
MultiMerge DTV 5.1 Surround Audio Processor Encoder/Decoder with DTS Neural Loudness Control
TheMultiMerge DTV is a complete surround and loudness solution for your transmission facility.
Combining the features of our popular DTS Neural Surround™UpMix and DownMix, MultiMerge DTV will automatically upmix stereo or encoded stereo content to near-discrete 5.1 surround sound using the latest DTS Neural Surround™ UpMix HD process, and simultaneously render an Lt/Rt output for 5.1 audio using the DTS Neural Surround DownMix process; optional DTS Neural Loudness Control maintains the loudness target for the 5.1 output and ensures CALM compliance using industry-standard ITU-R BS.1770/1 loudness measurement and the proprietary DTS Neural Loudness Control - all in 1RU.
Key Features of the MultiMerge DTV
- UpMix HD algorithm for near-discrete 5.1 performance from stereo
- Auto-UpMix provides full-time 5.1 output from mix of stereo and 5.1 content input
- Mute-less 5.1 pass-through to guarantee critical audio is never lost, such as center channel dialog
- Full-time LtRt stereo downmixed output from discrete 5.1 content
- EAS/CAP input for transmission of Emergency Alert messages
- Ethernet interface for compliance logging and field updates
- Optional DTS Neural Loudness Control and ITU-R BS.1770/1 Loudness Measurement - ensures CALM compliance
- Optional HD/SDI input for 8 de-embedded audio channels from SDI group 1 or 2
MultiMerge DTV accepts 2.0 or 5.1 audio and EAS/CAP audio, and automatically upmixes only when necessary, enabling broadcasters to deliver compelling 5.1-channel surround sound while saving time, money and space. The new UpMix HD algorithm outperforms all existing upmixing methods for channel discreteness, envelopment, and original spatial location regardless of source (Lt/Rt, Lo/Ro, ProLogic, ProLogic II or SRS Circle Surround). MultiMerge DTV also delivers full-time two-channel downmixing, LtRt from discrete 5.1 content and LoRo from Stereo 2.0 content, to support legacy stereo and archive-replay paths.
A set of user-definable alarms can alert an operator of input loss and hardware faults. An Ethernet interface provides PC logging and field software updates.
Optional DTS Neural Loudness Control for MultiMerge DTV maintains the broadcaster-defined loudness level without the annoying side-effects of traditional energy-based volume management solutions; industry-standard ITU-R BS.1770/1 loudness measurement maintains broadcaster-defined loudness level across all audio programming to minimize viewer complaints while ensuring CALM compliance.
Other options include HD/SD-SDI input for 8 de-embedded audio channels from SDI group 1 making MultiMerge DTV a very cost-effective, total content delivery solution.
