LTC and VITC timecode inputs allow automatic configuration changes in a broadcasting environment. The DP569 supports encoded bit rates from 56 to 640 kbps and channel configurations from mono to 5.1-channel surround sound. More than 7 million consumer products equipped to decode programs with Dolby Digital audio are already in use, from DVD players to set-top boxes. Dolby Digital also allows tailoring the number of channels and bit rates for various applications, such as 5.1 (at 384 to 448 kbps) for consumer surround or two channels (at 192 kbps) for stereo programming. AC-3 provides six channels of surround sound information in the 5.1 format, using the psychoacoustic phenomenon known as auditory masking and both inter- and intra-channel redundancy for the efficient storage and transmission of digital audio.īut beyond its application in feature film presentation, Dolby Digital has been used on laserdiscs, and it is the audio format for DVD-Video, SCTE digital cable TV and the audio standard for ATSC digital broadcast TV. Since its debut in 1992 with the film Batman Returns, Dolby Digital (AC-3) has been used on hundreds of films. The DP562, a companion reference decoder, is $3,600. Now, with its DP569, Dolby has brought the cost of a professional reference encoder down to an affordable $5,000, while offering more features than did the product’s predecessor and fitting the unit into a single-rackspace chassis. And although the price of a Dolby Digital reference encoder has dropped from $50,000 to $30,000 to $19,600 over the years, it was still on the pricey side for studios that needed an encoder only occasionally. Up until now, many producers skipped this vital step, due to the cost of hardware.
