Qrodo Live: Stockholm Kendo Open

Monday, October 20, 2008

On Saturday October 18 Qrodo live-casted Stockholm Kendo Open over the Tre 3G mobile network. We used one semi-pro Sony DV camcorder using resolution 752×520. The uplink from Tre (www.tre.se) was very reliable at 800 Kbit/s and up to 1,2 Mbit/s. We experimented with two configurations of Qrodo, during the event, one with 25 frames/s and one with 15. The higher quality stream was steady around 500 Kbit/s, but went up to 1,3 Mbit/s when we used zoom and pan, which is understandable as the video encoding is based on deltas, when the scene changes alot the bitrate goes up significantly. The lower quality stream was streaming at 300 Kbit/s and topped at 800 Kbit/s for agressive camera management.
