There is a video on Cnet.com, a caller asked the Cnet folks what is better SIRIUS or XM?!?!? In this video clip the Cnet.com guys talked about SIRIUS having an edge on getting "Dozens or hundreds more stations.." You can watch the video here. SIRIUS hinted at this new technology back in June in the PR. "New Modulation Technology Will Initially Increase Current System Capacity by Approximately 25%, Enabling SIRIUS to Expand Offering of Audio, Data and Video Services While Maintaining Broadcast Quality"
SIRIUS has developed a new, advanced proprietary technology that will initially increase the company's total network capacity by approximately 25% within its existing digital transmission system. The technology, known in the industry as hierarchical modulation, will allow SIRIUS to offer additional audio channels, as well as advanced services such as data and video, without affecting the quality of its broadcasts."Our new modulation technology will use a very innovative approach to increase the number of bits we transmit through our satellite and terrestrial repeater networks, enabling us to increase the effective use of our currently licensed spectrum to add additional programming for the benefit of our subscribers," said Jim Meyer, SIRIUS President, Sales and Operations. "Sirius will continue to deliver uncompromised sound quality, and with this new technology we will retain the flexibility to expand our broadcasts even further in the future."
The technology, developed by SIRIUS' Advanced Development Team based in Lawrenceville, NJ, will work over SIRIUS' current network, with minimal upgrades to its satellite uplink and terrestrial repeater infrastructure. SIRIUS has already conducted several tests of the technology to confirm the performance. The new modulation technology will not impact the customer experience of existing SIRIUS radios sold or currently on the market. Future SIRIUS radios will be outfitted with the new technology, making it possible for them to receive the additional services planned.
The company expects to begin offering services using the new technology in the second-half of 2006.
We are told that SIRIUS hinted to this at CES to a closed door room of retail VIP's... We are told that in the June 2006 time frame news SIRIUS chips will be out and this hierarchical modulation technology will be in new units.
Chat more about this in the GSI Forum...
