MultiMerge TV Dual Stereo-DownMix with DTS Neural Loudness Control.
MultiMerge TV Dual Stereo-DownMix with DTS Neural Loudness Control
The MultiMerge TV is a very cost-effective two-channel stereo loudness solution for your transmission facility.
Combining the features of our popular DownMix and DTS Neural Loudness Control products, MultiMerge TV will process discrete 5.1 to render an Lt/Rt output using the DTS Neural Surround™ DownMix process and maintain the loudness target for two stereo or SAP outputs while ensuring 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 TV
- DTS Neural Surround™ DownMix provides full-time 2.0 output from mix of stereo and 5.1 content input
- DTS Neural Loudness Control and ITU-R BS.1770/1 Loudness Measurement - ensures CALM compliance
- EAS/CAP input for transmission of Emergency Alert messages
- Ethernet interface for loudness compliance logging and field updates
- Optional HD/SDI input for 8 de-embedded audio channels for SDI group 1 or 2
MultiMerge TV accepts 5.1-channel network audio and two-channel local audio or SAP/DVS along with EAS/CAP audio, and automatically downmixes only when necessary, enabling broadcasters to process two channels of stereo audio while saving time, money and space.
The breakthrough DTS Neural Loudness Control built into MultiMerge TV 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.
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.
Available options include HD/SD-SDI input for 8 de-embedded audio channels from SDI group 1 or making MultiMerge TV a cost-effective, total content delivery solution.
