UpMix NLC Higher Definition Surround Audio Decoder-Loudness Control.
UpMix NLC Higher Definition Surround Audio Decoder-Loudness Control
The UpMix NLC is a very cost-effective surround decoder andloudness solution for your transmission facility.
Combining the features of our popular UpMix and DTS Neural Loudness Control products, UpMix NLC will upmix stereo or encoded stereo content to near-discrete 5.1 surround sound using the latest DTS Neural Surround™ UpMix HD process, and maintain the loudness target and ensure 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 UpMix NLC
- 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
- DTS Neural Loudness Control and ITU-R BS.1770/1 Loudness Measurement - ensures CALM compliance
- EAS/CAP input 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
UpMix NLC 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).
The breakthrough DTS Neural Loudness Control built into UpMix NLC 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 2 making UpMix NLC a cost-effective, total content delivery solution.
