| DTS Offers Audio Solutions for Next Generation Optical Disc Formats DTS unveils a three-tiered system of audio solutions for the next generation HD DVD and Blu-ray Disc formats. The naming system is a scalable architecture that can support a variety of different quality levels in a single stream. Designed to provide flexibility for content providers and immediate audio improvement with existing home theater equipment, the solution entails a series of new logos that communicate the varying quality levels to consumers: DTS-HD Master Audio, for sound bit-for-bit identical to the master soundtrack, DTS-HD High Resolution Audio, for audio that is nearly identical to the master soundtrack, and DTS Encore, which delivers 5.1 channels of audio at twice the resolution found on most standard DVDs. DTS-HD Master Audio delivers sound that is bit-for-bit identical to the studio master. It can deliver audio at very high variable bit rates which are significantly higher than standard DVDs. DTS-HD Master Audio can provide up to 7.1 audio channels at 96k sampling frequency/24-bit depths that are identical to the original. The DTS-HD Master Audio bit stream also contains the DTS 1.5 Mbps core for compatibility with existing DTS-enabled home theater systems, and delivery of 5.1 channels of sound at twice the resolution found on most standard DVDs. DTS-HD High Resolution Audio can deliver up to 7.1 channels of sound that is virtually indistinguishable from the original soundtrack. It provides audio at high constant bit rates superior to standard DVDs to produce outstanding quality. It can carry up to 7.1 channels at 96k sampling frequency/24-bit depth resolution, thereby allowing content creators to provide rich, high definition audio on content where disc space may not allow for DTS-HD Master Audio. The DTS-HD High Resolution Audio bit stream also contains the DTS 1.5 Mbps core for compatibility with existing DTS-enabled home theater systems, and delivery of 5.1 channels of sound at twice the resolution found on most standard DVDs. DTS Encore delivers 5.1 channels of audio at 1.5 Mbps - twice the resolution found on most standard DVDs, thereby providing the best sound performance possible from currently existing DTS-capable equipment. Due to space limitations on the standard DVD format, most DVD content featuring DTS surround sound is encoded at 768 kbps. However, with the introduction of the new higher capacity high definition optical disc media, consumers will be able to experience the DTS core at a full 1.5 Mbps, resulting in an immediate improvement in sound quality even if a next generation player is connected to standard home theater hardware. write your comments about the article :: © 2006 Computing News :: home page |
