Motorola Cable Boxes To Get Dolby Volume


Las Vegas - Dolby technologies of various stripes will appear in multiple new products here at International CES, where Motorola announced plans to incorporate volume-leveling Dolby Volume technology in a line of cable-TV set-top boxes.

In cable boxes, the technology 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. The technology will also appear in new TVs to be announced this week at CES by a supplier that adopted the technology last year.

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, at least one more A/V receiver (AVR) maker will launch its first AVRs with Dolby Pro Logic IIz, which adds front-height channels to 5.1- and 7.1-channel home theaters. AVRs from Denon, Integra, Marantz and Onkyo already offer the technology.

In addition, at least two laptop makers, one PC maker and some netbook makers will launch new products incorporating the company's Dolby Home Theater suite of technologies, Dolby said. Their names will be released in coming days. The Dolby Home Theater suite of technologies is already used by HP, Toshiba, Sony, Lenovo and Acer, Dolby said. The Home Theater suite of technologies 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.
