Mobile Users Frustrated by Mobile Video Experience
Saturday, September 25th, 2010
A survey of U.K. mobile users finds 96 percent are frustrated with their mobile video experience. In part, that likely reflects latency and bandwidth limitations that affect the quality of video content.
About 67 percent are discouraged by non-continuous video playback and the length of time it takes a video to begin playing, as well.
Of the 16 to 24 year olds surveyed, 69 per cent of users prefer video to be optimized, rather than wait significantly longer for higher-quality streaming, the study suggests.
That might be seen by some as an argument in favor of prioritizing some bits, such as video or voice, under conditions of congestion. The other suggestion will be that mobile operators need to provide more bandwidth. The problem there is the same as we face in major metro areas when new freeways are built. Traffic always builds to clog even the new capacity. That will especially be true as mobile video consumption grows.
