The M6205A-3G +NLC5.1ST is a sophisticated audio processing platform card with optional processors designed for broadcast use. It can extract and process up to 16 channels of audio embedded in a digital video stream. The M6205-3G accepts 3G, HD-SDI and SD-SDI signals. In addition two AES inputs are provided to enable substitution of the embedded audio signals. The card may also be used as a one group embedder. Functions of the card include channel shuffling, channel replacement or substitution, and mixing.
+NLC5.1ST Surround Loudness Control measures and controls perceived loudness of the program audio using the industry-standard ITU-R BS.1770/1 as well as DTS-NeuralTM Loudness Measure (NLM) and DTS-Neural Loudness Control (NLC) algorithms. The proprietary NLC and NLM algorithms were developed by DTS after extensive research into human hearing and perceived loudness.
Guarantees a consistent viewer experience despite variations in consumers' equipment
Adheres to the ITU BS.1770 loudness recommendation, and--more importantly--agrees with your viewer's perception of loudness
Uses the same loudness control for stereo and 5.1 surround content
Manages loudness without a squashed or compressed sound
Corrects loudness while preserving the original equal loudness curve
Using predicting technology, makes large gain corrections imperceptible
DTS Neural Loudness Control (NLC) technology is an advanced loudness leveling technology that accurately measures and regulates the perceived loudness differences in audio. Annoying side-effects of traditional audio processing are eliminated and loudness is controlled without squashing the quality of the audio. The result is audio with a natural, open quality and a consistent audio experience for all viewers.
DTS NLC mimics human perception of audio and provides accurate control of loudness. DTS Neural Loudness Control detects spectral and density differences, inter-channel relationships and temporal overlaps within the audio signal. After loudness measurement, DTS Neural Loudness Control technology applies the appropriate gain or attenuation to the audio to achieve a user-defined loudness level.
The M6205A-3G extracts, processes, and re-embeds the audio providing two SDI outputs with the embedded processed audio. In addition the card provides AES copies of the processed audio. The M6205A-3G complies with SMPTE 272M, SMPTE 299M, and SMPTE 424M standards. Cable equalization and reclocking techniques enable the M6205-3G to recover the incoming 3G, SD-SDI or HD-SDI signal reliably. The M6205A-3G is housed in the openGear DFR-8300 series frames.
