At NAB 2006, Linear Acoustic and Coding Technologies, a provider of audio compression for digital broadcasting, mobile media and the Internet, announced that Linear Acoustic has developed an aacPlus surround-sound encoder and decoder to accommodate Dolby-E Metadata format directly throughout the broadcasting transmission chain. Such functionality will dramatically simplify the integration of the Linear Acoustic range of encoders within existing broadcast environments, and speed the adoption of the aacPlus audio compression format for digital multichannel broadcasting.
The two units - AEROMAX-aacPlus Professional Encoder and Decoder – can be seen at Booth C2507B.
Coding Technologies’ MPEG-4 aacPlus audio codec is standardized across a variety of platforms as a compression format for digital audio, including DVB, MPEG, 3GPP and other international standards. In digital broadcasting, aacPlus has a proven track record as the audio codec for XM Satellite Radio. Compared to current 5.1-channel coding systems, including Dolby AC-3, aacPlus reduces broadcasting bandwidth and transmission costs to less than half, and frees up limited bandwidth resources for additional programming in fixed, existing channels.
