Powell to Resign as FCC Chairman
Washington - Jan 21, 2005 - In a letter sent to President Bush, FCC Chairman Michael Powell will resign his post as the agency's leader. Powell released the following statement:
Today, I sent a letter to the President thanking him for the incredible privilege of chairing the Federal Communications Commission during his first term. With a mixture of pride and regret I informed him of my intention to step down as a commissioner and chairman some time in March.Commissioners Abernathy and Copps released statements praising Powell for his work at the Commission.
Having completed a bold and aggressive agenda, it is time for me to pursue other opportunities and let someone else take the reins of the agency. During my tenure, we worked to get the law right in order to stimulate innovative technology that puts more power in the hands of the American people, giving them greater choices that enrich their lives. Evidence of our success can be seen increasingly in the offices, the automobiles and the living rooms of the American consumer.
The seeds of our policies are taking firm root in the marketplace and are starting to blossom. The use of cell phones, digital televisions, personal video recorders, and digital music players, is exploding. These devices are increasingly connected anytime, anywhere by a wide variety of broadband networks enabling a host of competitive services and new applications. Our children will inherit this exciting future.
My only significant regret is that I will no longer have the pleasure and privilege of working shoulder to shoulder with the most talented and dedicated staff and colleagues that I have known. I look forward to spending some time off with my wife and two boys, before taking up my next challenge. They have been wonderfully supportive and patient.
Powell was a strong advocate of broadband access in many forms, and also pushed for communication services to be provided in remote areas that are underserviced. The resignation will take effect in March. Powell served as FCC chairman for four years. He was appointed to the Commission in 1997 by President Clinton.
Commissioners Kevin Martin and Kathleen Abernathy have been mentioned as possible successors to Powell, but come analysts believe the next chairman will come from outside the agency. Top candidates are believed to be Becky Klein, a former head of the Texas Public Utility Commission; Michael Gallagher of the National Telecommunications and Information Administration; and Janice Obuchowski, a telecom consultant who served in the Commerce Department under the elder President Bush. Other names mentioned include former Interstate Commerce Commission Chairman Darius Gaskins and former Federal Trade Commission Chairman Jim Miller.
Indiana Tower Climber Rescued from Tower
West Terre Haute, IN - Jan 18, 2005 - The Associated Press reports that tower climber Alan Cook passed out while climbing a 635-foot tower. Cook was at the 475-foot level. Cook's coworker, Mike Norman, called 911 to get help, but Cook dangled in his harness for nearly two hours before he could be helped down.
Cook is an employee Midstate Telecom of Decatur, IL. Reports say that he drifted in and out of consciousness in the 20-degree temperatures. A firefighter, Hidekatsu Kajitami, climbed the tower and tethered Cook to a rope system in an effort to lower him to the top of a 90-foot ladder. In his disoriented state, Cook continued to grab the tower. Norman had to repeatedly move the rope to keep his coworker from grabbing the tower.
Cook was treated and released from a local hospital.
Patents Pressed Against File-Sharing Networks
Sherman Oaks, CA - Jan 20, 2005 - A software company and its parent are claiming that they hold patent rights to widely used Internet file-swapping technology, and they are demanding that several file-sharing networks obtain licenses to continue operating, the Washington Post reported.
Attorneys for Altnet and its parent company, Sherman Oaks, CA-based Brilliant Digital Entertainment, sent letters to several U.S.-based file-swapping firms -- including Lime Wire, Bear Share operator Free Peers and Mashboxx -- claiming that the companies were using patented technology in their products. The letter doesn’t explicitly threaten a lawsuit but does invite the firms to "discuss licensing opportunities."
"You could call it a warning. We call it an offer to license our technology," said Lawrence M. Hadley, counsel for Altnet and Brilliant Digital.
A valid patent would give the firm a tight hold on a popular means of identifying and trading digital copies of music, movies and software, just as a fledgling industry has sprung up to turn file sharing into a commercial enterprise.
Altnet has already signed a licensing deal for the technology with one of the largest peer-to-peer companies, Sharman Networks, which is based in the Republic of Vanuatu and is the firm that distributes Kazaa. Altnet's software allows users to purchase licensed copies of music over the Kazaa network, the Post reported.
Several recipients of the letters predicted that Altnet's patent claims are likely to be challenged.
The technology at issue is "hashing" -- a method for assigning a unique tag or "hash" to a digital file. By comparing the hashes, rather than entire files, file-swapping software can quickly process users' requests for specific songs, movies or other files.

Shively Labs Selected for Sylvan Tower Facility
Portland, OR, and Bridgton, ME - Jan 21, 2005 - Shively Labs it has been selected by KBPS Public Radio Foundation, Mt. Hood Community College and Catholic Broadcasting Northwest, to supply a broadband panel antenna system and combiner for the stations' new Sylvan Tower facility in Portland, OR. The Model 6014 broadband panel antenna and the Model 2640 balanced combiner system will be configured for HD Radio use. The panel antenna features dual inputs for redundancy and a fail-safe pressurization system. The Shively panel antenna was selected after evaluation of measured coverage patterns performed on Shively's pattern range. The coverage is of particular concern to the customers because of the large facewidth tower used at the site.
The Sylvan Tower facility will be the first installation to use the Model 2640 low-power balanced combiner. The combiner is based on Shively's interdigital design and features a small footprint and cross module patching to allow each station to swap its digital and analog feeds. The combiner will accommodate the digital signal using a back feeding technique.
Iraqi Media Network Contracts Harris
Melbourne, FL – Jan 20, 2005 - Harris has been awarded a three-month, $22 million contract by the Iraqi Media Network (IMN). The contract scope includes training, programming support, systems integration and deployment work for IMN, the country's public television and radio broadcasting organization. The network operates locations in Baghdad and in more than 30 other locations throughout the country. Funding for the contract will be provided solely by the Iraqi government.
Work on a previous IMN contract was completed in early January. Originally awarded to Harris in January 2004 by the Defense Contracting Command, that contract scope included requirements for broadcast and printing equipment, broadcast studio and transmission systems design and integration, network operations, and employee training.
The Harris team completed construction of a news studio and an entertainment studio in central Baghdad. The public television network, Al Iraqiya, now has a 24-hour news desk and programming that features 80 percent Iraqi content including news, sports, business and weather coverage. Public radio programming includes talk and music formats. IMN has full capability to produce live entertainment and news commentary programs. Harris was supported by the Lebanese Broadcasting Corporation International (LBCI) and Al Fawares, a Kuwaiti company with Iraqi ownership, on the project.
APT Celebrates the New Year With ORF in 5.1
Vienna - Jan 20, 2005 – Austria's public broadcaster ORF transmitted its popular New Year Concert 2005 in 5.1, using APT's Enhanced Apt-x Worldnet Skylink Multichannel audio encoders/decoders to handle the audio transmission over IP and ATM networks.
The Dolby Digital 5.1 radio mix of the concert, which was broadcast live as a trial transmission, was streamed via APT's Worldnet Skylink encoder across a 2Mb/s XDSL link to the ORF ATM network. There, the signal was decoded using the Worldnet Skylink decoder and mixed with announcements and other multichannel sources using ORF's Acousta D500 5.1 mixer. Finally, the ORF TV Centre distributed it to the Astra IH satellite uplink using its new ORF-Transponder 115.
Audiences across Europe were able to receive the concert, which was free to air, via their standard digital satellite set-top boxes.
To transmit multichannel audio for the new service, ORF will use Austrian Telekom's high-bandwidth broadcasting network for audio and video, which was established five years ago. This LNET, which is already being used to transmit stereo signals, connects the broadcaster's main studios in Vienna and eight other cities to ORF's main transmitter site.
A number of the codecs used for the LNET have recently been upgraded to incorporate APT's Enhanced Apt-x algorithm.
Sirius to Offer Satellite TV Service for Cars in 2006
New York - Jan 20, 2005 - Sirius Satellite Radio has announced plans to offer a satellite TV service for cars in the second half of 2006. The service will use Microsoft's Windows Media platform and offer several channels of children's programming. The satellite radio operator said it will also work with Microsoft for "further development of video applications." No agreement has been reached with automakers to support the service.
Sirius and XM are vying to win customers with exclusive programming and by including receivers in cars. Neither company has had a quarterly profit and they need at least 40 million subscribers to succeed.
Sirius said it was creating the service amid demand from automakers, which are including TV screens in the back seat of models designed for families. Ford Motor, Daimler-Chrysler and BMW already offer Sirius's receivers as a factory option. Those companies have shown preliminary interest in the video product. The company plans two to three channels, which might feature cartoons and music videos.

IBM Opens 500 Patents for Open Source Use
Armonk, NY - Jan 11, 2005 - IBM has allowed open access to innovations covered by 500 IBM software patents to individuals and groups working on open source software. IBM believes this is the largest pledge ever of patents of any kind and represents a major shift in the way IBM manages and deploys its intellectual property portfolio. The access applies to any individual, community or company working on or using software that meets the Open Source Initiative (OSI) definition of open source software now or in the future.
IBM intends for this pledge to form the basis of an industry-wide "patent commons" in which patents are used to establish a platform for further innovations in areas of broad interest to information technology developers and users.
Open source software, based on collaborative innovation among developers around the world, is gaining significant marketplace momentum. IBM believes that the patents it is releasing to open source developers will help foster continued innovation.
The patents cover dynamic linking processes for operating systems, file-export protocols and other technologies. The pledged patents and further related information will be posted on IBM's website ata href="http://www.ibm.com/ibm/licensing/patents/pledgedpatents.pdf" target="new">www.ibm.com/ibm/licensing/patents/pledgedpatents.pdf.

Sirius Licenses Digital Fountain Meta-Content Technology
Fremont, CA - Jan 17, 2005 - Sirius Satellite Radio has signed a licensing agreement to use Digital Fountain's Meta-Content technology in upcoming products. Over time, the companies expect that Digital Fountain technology will be incorporated into all Sirius Satellite Radio receivers. Sirius has licensed Digital Fountain's latest generation of technology which is known as Raptor, a forward error correction (FEC) technology.
Meta-Content technology allows for efficient data reception when devices receive data at random and intermittent intervals, as is often the case with automotive receivers. For example, when using Meta-Content technology to receive a broadcast of a file, devices need only collect any set of packets about equal in length to the original data package to instantly and perfectly recreate the original data. Because there is no need to worry about which packets any particular receiver collects, the data is received quickly and reassembled accurately, even amidst intermittent reception schedules and frequent broadcast interruptions.
Raptor codes are rateless, meaning there is no limit on the amount of unique encoded data that can be generated. Also, the codes have the property that encoding and decoding calculation requirements are linear with respect to the size of the source data. This contrasts to conventional coding technologies where calculation requirements increase at an accelerating rate with larger size.

Harris, Midwest Radio Systems Upgrade System in St. Louis
Cincinnati - Jan 18, 2005 - Harris and Midwest Radio Systems have sold and installed Intraplex Synchrocast multiplexers for the Jefferson County Sheriff's department and 911 dispatch located near St. Louis, MO. The system will increase coverage and broaden market reach by operating multiple overlapping transmitters on the same frequency. To meet Jefferson County's need for a more reliable infrastructure and support network to serve its dispatch center, Harris was contracted to install its Intraplex multiplexers with Synchrocast at five sites, enabling each with five-channel simultaneous communication with seven site receivers per channel.
Jefferson County receives nearly 100,000 calls per year, transmitting to 24 remote fire, police and EMS agencies. This is made possible by GPS satellites and precision digital timing; signals from five transmitters simulcasting together to eliminate artifacts at the listener's receiver. The Harris Intraplex Synchrocast system allows Jefferson County's dispatch to reach 95 percent of the area. Additionally, it can support future data broadcasting initiatives as the technology supports a voice-data network, eliminating the cost of future base-station, transmitter, or other infrastructure investments.
