DTS for Surround Sound
Why choose DTS for Surround Sound?
Some years have past since the first releases of DTS encoded material on DVD and the emergence of DTS equipped home receivers. A staggering growth in licensees of DTS decoding technology has been seen over the past few years. The to the point that equipment available to home listeners now includes DTS decoding almost as a default, meaning that DTS is a format that has emerged and is here to stay. What is more, it has emerged due to superior quality and discerning user preference.
Quality DTS is measurably the most superior quality broadcast compatible audio codec. DTS should not be regarded as a mere audio compression algorithm. It is an extremely clever and well thought out data transmission format. DTS offers flexibility, scalability and ease of use and if these are important to you, then you should read on.
Flexibility DTS offers broadcasters the complete solution in delivering top quality format from mono through stereo up to 5.1 and beyond. DTS offers the unique capability of delivering 6.1 discrete for broadcasters. DTS is also unique in enabling broadcasters to select the sampling rate: 44.1kHz, 48kHz or 96kHz.
Backward Compatibility
The patented DTS architecture removes all concerns about full backward compatibility to even the oldest DTS decoder. So, go ahead and push the technological limits with 6.1 or 96kHz: your audience will still enjoy it to the fullest extent of their decoders ability, in 5.1, in 96kHz, or whatever configuration their DTS decoder has. Broadcasters who are understandably reluctant to implement technology that is unable to be received by their entire audience welcome DTS. Enhancements like 6.1 discrete and high-resolution 96kHz that are normally viewed skeptically can be integrated without fear of reaching DTS equipment not capable of these formats. DTS carries the ability to decode on all DTS equipment choosing in each case the best available quality that equipment can offer. If you are broadcasting in 96/24 DTS format, a 48kHz system will receive and successfully decode these signals at the best available quality, automatically.
Scalability The core DTS specification and supporting broadcast hardware encoding platform allow broadcasters to choose whatever audio bandwidth they wish to transmit, currently up to 1.5 Mbps. Therefore, broadcasters can allocate more audio transmission bandwidth, greater coding accuracy and higher quality sound for special events such as movie premieres, concerts or flagship programs. Using higher bandwidth DTS audio compression techniques, it is possible to match and even better the audio quality currently found on DVD material.
Ease of implementation The DTS proposal loads the MPEG-2 stream with Packetised Elemental Streams (PES) in a similar way to that utilized by AC-3. Any device that supports AC-3 can be readily used for DTS transmission, which means that a broadcaster does not require massive re-investment in infrastructure to support DTS transmissions. DTS also performs well through multiple cascades, so theres no need for major changes in workflow. Broadcasters will also appreciate the possible use of high bitrate DTS for their contribution network and for archiving purposes. not require massive re-investment in infrastructure to support DTS transmissions.
