NDS Provides Conditional Access for HD Radio
Las Vegas - Apr 16, 2007 - NDS has debuted NDS Radioguard, the first conditional access system for HD Radio. With the announcement of the product comes the news that NDS Radioguard has been chosen by Ibiquity to protect digital content transmitted over HD Radio. Ibiquity will embed the NDS technology into its chipsets moving forward.

NDS Radioguard in the HD Radio chipsets will allow broadcasters to offer pay-per-listen options for live concerts and events, opt-in events sponsored by advertisers and private channels for specific needs.

The conditional access system is used to scramble the signal and then entitle specific receivers to decode that signal. To do this, all HD Radio receivers will need to be addressable, which is a step that it now being implemented for future receivers. The decoding capability is being introduced in two steps. By September 2007, NDS will have a security chip available that will add the access capability to the existing HD Radio chipset. By April 2008, NDS and Ibiquity expect to have the capability imbedded within the HD Radio chipset.

The system has undergone field trials that were transmitted via WUSF-FM, Tampa, FL. The tests began on March 18 and were a cooperative effort between the station, the International Association of Audio Information Services, Ibiquity, Harris and NPR Labs. According to NDS, the tests went well and showed that receivers could be entitled to receive the reading service for the blind programming.

NDS technology is currently in use in more than 70 million TV set-top boxes around the world. This technology has been adapted into Radioguard.

NDS is exhibiting in booth N7137 at NAB2007, and the system will also be shown in the Broadcast Electronics and Harris booths.

Report States Flaws with Carmel/NAB View of Satellite Radio Landscape
Menlo Park, CA - Apr 10, 2007 - Telecom, Media and Finance Associates (TMF) released a research note on the competitive landscape for satellite radio in light of the proposed XM/Sirius merger. The research analyzes the positions taken by the Carmel Group in its recent white paper on behalf of the National Association of Broadcasters and concludes that Carmel "ludicrously overstates the case for opposing the merger of XM and Sirius and fundamentally misinterprets the competitive environment for satellite radio."

"Satellite radio is essentially a car-based audio service at present, so the primary alternative for consumers is free-to-air AM and FM radio, supplemented by the playback of pre-recorded music such as CDs," said Tim Farrar, author of the TMF report. "The competitive position of these subscription-free services vis-a-vis satellite radio has been substantially enhanced by the widespread use of accessory adapters, allowing...MP3 players to be connected to car stereos, and we estimate that today as many drivers have access to MP3 content in their vehicles as subscribe to satellite radio. Carmel Group's assertion that MP3 players are not even relevant to today's in-car audio market is quite simply bizarre."

Access the entire report at The report was produced independently, and was not commissioned, funded or instigated by XM, Sirius or any other party.

Radio magazine observation: It's obvious that if the only two satellite radio providers were to merge that one company would result. This, as the NAB states, would create a single source for this one form of entertainment in a narrowly defined space. It seems odd that the NAB will completely ignore satellite radio as being any kind of a threat to terrestrial radio, yet it will vigorously oppose the merger as being unfair to other forms of media with which the NAB believes satellite radio does not compete.

NAB Launches Technology Advocacy Program
Washington - Apr 9, 2007 - The National Association of Broadcasters (NAB) has created a long-term technology advocacy program designed to seek and facilitate development and commercialization of new technologies for radio and TV. The multi-year, multi-million dollar program will be named NAB Fastroad (Flexible Advanced Services for Television and Radio On All Devices).

NAB Fastroad is a result of the NAB Technology Advocacy Committee in accordance with the sustained priority placed on technology by NAB Joint Board Chairman Bruce Reese and NAB President David Rehr. Consisting of NAB Board members, the NAB Technology Advocacy Committee held its first meeting in March 2006 and subsequently conducted a year-long deliberative decision-making investigation, including briefings by outside consultants, economic and technical analysis of technology developments, and technical review of potential projects through a technology discovery group process. Based on this work, the NAB board of directors decided unanimously in January 2007 to launch the program and the NAB's Executive Committee approved organizational details in late March.

NAB Fastroad will be managed overall by a steering committee consisting of NAB executive staff, board members and other representatives from NAB broadcast member organizations. Project selection and implementation will be handled by a technical committee of selected NAB member company engineers and staff from the NAB Science and Technology Department. Participation by NPR Laboratories and MSTV has also been established to coordinate with other ongoing technical programs in the radio and TV broadcasting sectors. The program will principally concentrate on technologies and services related to over-the-air digital transmission.

Tieline Launches Interoperability Over IP with other Brands
Indianapolis - April 9, 2007 - As telco providers cut back and in some cases discontinue offering ISDN service in the United States and Europe, the European Broadcast Union (EBU) is establishing operability standards that will allow IP codecs from different manufacturers to communicate with each other. At NAB2007, Tieline Technology will demonstrate codecs that are compliant with the new audio-over-IP interoperability standards issued by the EBU.

While most ISDN codecs have been able to establish ISDN connections regardless of the manufacturer for more than 10 years, IP connectivity does not always provide the same cross-compatibility. The EBU is establishing a global standard for broadcasting via IP networks and interoperability between codec brands.

Part of this compatibility includes the use of the Real-time Transport Protocol (RTP), which defines a standardized packet format for delivering audio and video over the Internet, and Session Initiation Protocol (SIP ), an Internet application-layer protocol that allows audio and video sessions to be established over the Internet. SIP provides many features to simplify a codec connection across the Internet including the ability to register a name or number to a codec to simply dialing via a SIP server; a mechanism to allow the best algorithm that is common to both codecs to be used; correctly setting sample rate, bit-rate and mono/stereo mode; and an option to send only, receive only or standard send/receive mode.

Tieline plans to extend its support for phone voice mode to include SIP VoIP over IP connections. Tieline now offers voice-mode connectivity on POTS, GSM, ISDN and IP.

Tieline codecs featuring SIP interoperability will be demonstrated at Tieline's NAB booth, N9311.
