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.
