PictureTel Expands Interoperability

PictureTel Corp. is expanding the interoperability of its new Siren audio codec, having just signed a licensing agreement with Nortel Networks Corp. The codec is capable of creating high-quality audio at the 7- to 14-kHz range, as compared with a phone, which operates at around 3kHz. Siren is also the basis for the ITU G.722.1 audio standard. PictureTel has licensed the codec to Microsoft Corp., Intel Corp., Radvision Ltd. and Accord Networks Inc.
