Dolby focuses on Audio for HD and 3D

Dolby used CES as a platform to demonstrate how to enhance viewing of 2D or 3D with its audio lineup.  “When you combine HD and 3D, it is screaming for the audio experience,” commented Ramzi Haidamus, Dolby’s executive vp, sales and marketing.

Dolby also showcased new devices and media that support Dolby Digital Plus high-definition audio, including VUDU.  The service uses Dolby Digital Plus to deliver 5.1 surround sound.  For Blu-ray, it supports primary 7.1-channel audio as well as multichannel secondary audio support.

Dolby reported that Dolby TrueHD, a lossless compression technology developed for HD disc-based media, has been used for more than 560 Blu-ray Disc movie titles, including Paramount’s “Star Trek,” which was highlighted at CES.

The company also featured Dolby Pro Logic IIz, the company’s matrix decoding audio technology that supports 7.1- or 9.1-channel audio.

When asked about 3D video for the home, Haidamus said Dolby was in the R&D phase.
