Mobile TV Broadcast

Low-Bit Rate Audio Broadcast Now a Reality

Neural-AMR-WB+ with Neural Surround is an exciting new audio compression technology that efficiently delivers monaural, stereo and surround sound audio. And it greatly improves the mobile-TV consumers' entertainment experiences of speech, music and mixed-audio content.

Neural-AMR-WB+ allows a wide range of new mobile entertainment applications. With bit rates lower than 72kbps, this innovative technology uses communications bandwidth with extraordinary efficiency, but still delivers an immersive, TV-quality surround sound to car entertainment systems using Neural-AMR-WB+ enabled services.

Partnership with VoiceAge

Neural Audio has partnered with VoiceAge Corporation, a leading developer of speech and audio codec and inventor of the AMR-WB+ codec. Combining Neural Audio Pre-Processing with AMR-WB+ allows innovative parametric stereo processing prior to audio encoding and improves the AMR-WB+ audio coding performance.

The Problem

Mobile TV service providers face numerous challenges to growth and mass-market success. Consumers keep demanding better audio quality and a broader choice of specialty content. But wireless transmission bandwidth has limited capacity and matrix-style surround playback tends to unmask digital audio coding artifacts.

The Solution

Neural-AMR-WB+ with Neural Surround alleviates all of these concerns. Surround content can be encoded and compressed without perceptible artifacts. And with an audio stream at bit rates lower than 72 kbps, high-quality surround-encoded content can be played back in either stereo using headphones or speakers or in full surround sound using a Neural Surround home or car entertainment system.

How Does It Work?

The Result

Neural-AMR-WB+ with Neural Surround provides efficient and superior quality audio streaming and downloading. Mobile entertainment experience improves, listener satisfaction and retention increase due to the more natural sounding audio, and communication bandwidth use is reduced.

Using Neural-AMR-WB+, both network operators and consumers get more for less:

Neural Audio's Pre-Processing solutions have been used in combination with other audio codecs in a variety of applications. That's more than 20 million hours of broadcast time since the year 2000!
