Twyford, UK 22 July 2004 DTS (Digital Theater Systems, Inc.)
(Nasdaq: DTSI) demonstrated the viability of streaming high definition surround
sound audio over the Internet in a recent trial with Swedish Radio (SR). Audio,
mixed live in 5.1-channel surround sound from an outside broadcast, was encoded
at 24 bit, 96kHz using DTS Coherent Acoustics codec, and streamed onto
the Sprint Network via Internet protocol, at 1.5Mbs equivalent to full
DVD-V and DVB bit rate.
The event marked the first time that DTS Digital Surround has been streamed
over an IP network, and proves that high bit rate, high quality surround sound
audio can now be streamed using DTS, providing a common delivery format for
DVD, DVB and digital cinema.
Ted Laverty, Director of Business Development for DTS, explained, The
exercise arose out of our on-going cooperation with Swedish Radio and their
continuing DTS-encoded DVB satellite service. They are experiencing a fast-growing
demand for the high quality DTS downloads on their Web site (www.sr.se/multikanal),
and were keen to examine the viability of providing a streaming signal of the
same quality. The success of the transmission further establishes DTS as a convergent
technology, providing the same high quality, multi-channel audio across the
various content delivery channels.
The signal feed from the live concert also broadcast on SRs
DTS satellite transmission was encoded with a DVB MPEG2 encoder with
IP outputs. A DTS signal was streamed using Internet protocol live onto the
Sprint Network, and signal was successfully recovered using a proprietary DTS
software player designed for the purpose.
The success of the test proves the viability of very high quality audio multicasting
over broadband, and points to the evolving potential for IP delivery of digital
programming by broadcasters particularly in Europe where services offering
up to 8Mbits connections are starting to come online.
