IBC 2011 Preview
Hall 8, Stand D41
Miranda will be highlighting the world’s first loudness monitoring and correction processor for high program count, IP transport streams at IBC (Hall 8, Stand D41). Called Axino, the processor enables television service providers to address loudness control regulations around the world, including the Calm Act in the USA.
A single Axino processor provides continuous monitoring and selective loudness correction across hundreds of programs carried within an MPEG IP transport stream. The loudness monitoring and logging is performed using BT. 1770 and EBU standards, and the loudness control can address excessive segment-to-segment and program-to-program loudness. This processing prevents problems like overly loud commercials, and excessive variation in loudness during channel browsing.
The Axino processor is designed to integrate effectively with typical service provider workflows and contractual arrangements. For instance, whenever any program is excessively loud, the problematic signal is logged, and automatically put on a watch list. If this excessive loudness persists, the service provider can alert the content provider, and request a correction to the program. If this loudness problem is not resolved by the content provider, the service provider can activate Axino’s loudness correction, and bring the problematic program back within the target loudness range. This loudness processing is highly selective, and only impacts the specified programs.
Axino's high performance, audio processing uses Miranda's Automatic Loudness Control, which is used by broadcasters to correct thousands of television channels. With Automatic Loudness Control, the AC-3 audio is decoded from an IP stream for real-time loudness measurement and correction. After processing, the audio is reinserted back to its original location, and this ensures that the DIALNORM matches the actual loudness at all times.
All this audio processing is performed without adversely impacting the video quality, the video-audio synchronization, or the audio quality of the transport stream. The audio processing can be optimized by selecting loudness control profiles to best match the type of programming, and the speed of reaction required.
