96/24 DVD-Video Arrives
Analog Devices announced last week the availability to manufacturers of what it is calling the industry's first digital audio decoder for DTS's 96/24 5.1-channel high resolution audio format for DVD-Video. DTS claims to be the first to have developed 96/24 technology for 5.1 channel surround sound, while still allowing for full-motion video, on a DVD-Video disc.
According to Analog Devices, its Melody DTS 96/24 decoder enables installed DVD-Video players to deliver multi-channel sound at a 96kHz sampling rate and 24-bit word length, along with full-motion video. The company adds, "When encoded in the video zone of DVD-Audio discs, DTS 96/24 delivers 96/24 audio resolution on any existing DVD-Video player, eliminating the need for a separate DVD-Audio player." DTS says that the 96/24 soundtracks, on either DVD-Video or DVD-Audio, are fully backward compatible with existing DTS decoders, which will read and output a 48kHz signal.
Analog Devices says the Melody DTS 96/24 decoder has now been certified by DTS and currently designed into new A/V receivers from Denon (Model AVR-4802 and AVC-A11SR, which also use Analog Devices' AD1854K 96kHz/24-bit DACs) and Pioneer (Models VSX-49TX and VSX-47TX). The company adds that the SHARC DSP-based decoder additionally decodes DTS-ES Discrete 6.1 in each of these A/V receiver models.
The companies predict that "as the entertainment industry moves towards archiving material in 96/24 high resolution, the number of movies and music releases utilizing 96/24 on DVD-Video is expected to grow dramatically in the coming years." DTS publicly introduced 96kHz/24-bit high resolution for use on DVD-Video and DVD-Audio discs earlier this year at the Audio Engineering Society (AES) conference in Amsterdam.
