Key Features to be Illustrated During the On-going Demonstrations

* IP-to-IP gateway connecting WiFi and LAN networks
* Real-time audio transcoding from G.711 to G.729
* Multiple call handling (audio, video) simultaneously by a single DSP
* Voice conferencing between two G.711 terminals, two G.729 streams and two PSTN phones Streaming/recording of files from/to Host file system to/from mobile PDAs and video IP phones
* Resizing, logo insertion and background insertion in the video portal menus
* Real-time video transcoding from MPEG-4 to H.263
* Frame rate adaptation of content (streamed and real-time) from 30 FPS to 15 FPS on the IP terminals and 10 FPS on the mobile terminals
* Logo insertion in the streamed movies
* Video conferencing between four participants: two connected to the IP network, and two streamed files from the Host file system

Surf’s products are optimized for media gateway applications and media server/CTI/ messaging/ streaming/ recording/ conferencing applications. Audio and video streaming capabilities as well as audio and video mixing capabilities (including dominant speaker detection) are also supported. These solutions are provided on a variety of platforms: AMC/PTMC DSP farms as well as PCI cards and DSP chip-level. In addition, Surf has cooperation agreements with leading cPCI, ATCA and MicroTCA manufacturers to provide an integrated solution of Surf's AMC/PTMC mezzanine cards mounted on cPCI, ATCA and MicroTCA carriers.

Surf's approach is unique, since all other solutions separate audio and video processing and run them on different DSPs/sub-systems, or divide the processing between the host and the DSP. Running them together makes the solution more effective (cost, quality and performance-wise) since it enables dynamic (during run-time) modification of the channel to support audio applications now, and audio+video later.
