Dolby Labs Displays Dolby Pulse
April 8, 2009
Dolby Laboratories will show its Dolby Pulse at NAB. Dolby Pulse is the newest addition to Dolby’s comprehensive portfolio of high-quality audio technologies for the broadcast, mobile, CE, PC, and online markets.
Dolby Pulse is a complete system and encompasses a bitstream format as well as dedicated encoder and decoder solutions. It is compatible with the MPEG-4 HE-AAC (High Efficiency Advanced Audio Coding) open-standard audio codec. Dolby Pulse enables a single 5.1 stream to handle multichannel, stereo and mono signals with seamless switching. Meanwhile, dialnorm values embedded into broadcast streams can correctly set the loudness level, while preserving range.
The new Cat. No. 561 Dolby Digital Plus Encoder Module will also be on display at the NAB Show. The Dolby Digital Plus Encoder Module is designed for integration into third-party audio/video products featuring the new generation of video codecs such as H.264. The module offers broadcast equipment manufacturers the ability to add real-time multistream and multichannel encoding of Dolby Digital and Dolby Digital Plus audio bitstreams to their products.
The company will also show the Dolby DP600 Program Optimizer, which provides automatic analysis and intelligent correction of audio loudness and metadata (if applicable) for the most common broadcast media file and audio formats in use today. The system also offers the option of faster-than-real-time file-based encoding and decoding of Dolby Digital, Dolby Digital Plus, and Dolby E content, as well as efficient transcoding between the formats.
Dolby Laboratories will be at booth N1815.
