I just participated in very successful proof of technology with Siemens OpenScape video conferencing products.
We made a point-to-point SIP high definition video conference over a local area network. Another test used H.323 protocol. We also included my SIP-enabled Nokia E61i in the conference over the office WiFi network in a direct multipoint call simply calling my phone’s IP address. Crystal clear sound.
The equipment statistics showed the following:
- 1280×720 resolution (720p HD) at 30 frames per second
- H.264 compression
- aprox. 1780 kilobits per second for the compressed video stream
- AAC-LC compression
- aprox. 70 kilobits per second for the compressed audio stream
Total of aprox. 1850 kbps for excellent and smooth audio and video quality.
