Las Vegas - Dolby technologies of various stripes will appear in multiple new products here at International CES, where Sony announced plans to offer its first A/V receivers (AVRs) with Dolby Pro Logic IIz and Motorola announced plans to incorporate volume-leveling Dolby Volume technology in a line of cable-TV set-top boxes.

In AVRs, Pro Logic IIz post-processing technology adds a pair of front-height channels to 5.1- and 7.1-channel surround systems.

In cable boxes, Dolby Volume maintains a consistent perceived volume level when channels are changed and a TV program transitions to a commercial. Dolby Volume also dynamically and automatically compensates for the human ear's lower sensitivity to bass and treble sounds as volume levels decrease, ensuring that low- and high-frequency sounds are audible when a program's volume is automatically lowered to a user's preset listening level, Dolby said.

Dolby Volume already appears in audio products from ARCAM, Harmon Kardon, Sherwood, Bryston, Emotiva, Parasound, Onkyo and Integra. In these products, Dolby Volume also controls volume levels when switching among connected sources, such as Blu-ray players and cable boxes. In TVs, Toshiba added Dolby Volume to TVs last year and added the techno logy to its new Toshiba REGZA series LCD televisions here at CES.

In cable boxes, Dolby Volume will appear in Motorola's DCX family of set-top boxes for the North American and Latin American markets. The currently available DCX3400 HD-DVR and DCX3200 HD can be updated with Dolby Volume by cable operators. The DCX700 and DCX3300 HD set-tops will ship with Dolby Volume included. Consumers would turn on Dolby Volume through the settings menu of the DCX set-tops.

In other Dolby news, Sony announced plans to launch its first AVRs with Dolby Pro Logic IIz, joining AVRs from such companies as Denon, Integra, Marantz and Onkyo.

In other product launches, multiple new PCs, laptops and netbooks are launching with version 3 of the company's Dolby Home Theater suite of technologies, Dolby said. The Dolby Home Theater suite of technologies has been used previously by Hewlett-Packard, Toshiba, Sony, Lenovo and Acer. The Home Theater suite consists of Audio Optimization, High-Frequency Enhancer, Natural Bass, Dolby Headphone, Sound Space Expander, Dolby Pro Logic IIx and Dolby Digital Live, which converts soundtracks to Dolby Digital in real time for playback through connected CE devices.

Here at CES, new products launching with Dolby Home Theater v.3 include Sony's new F-series Vaio laptops and Lenovo's latest Ideapad laptops. Medion is also showcasing new PCs with Dolby Home Theater v.3, including the Medion Touch all-in-one desktop PC.

The Dolby booth also features Acer and Lenovo netbooks with Dolby Headphone to deliver surround sound through any pair of headphones.

Dolby is also highlighting Dolby Axon, a voice communication client for PCs. It improves voice clarity and surround sound for online gaming.

Dolby Digital Plus, the multichannel surround technology that's more efficient than Dolby Digital, is being carried over by such TV companies as Samsung, Sony, Toshiba and Sanyo for over-the-air broadcasts, Dolby said. But the technology is also appearing in these companies' new TVs to support the Vudu streaming video service, Dolby said.

In Blu-ray, the company announced that more than 560 Blu-ray Disc movie titles from 33 studios feature Dolby TrueHD, the multichannel lossless-compression soundtrack technology.
