Abstract
With the introduction of the next generation wireless network, mobile devices access increasingly more media-rich content. However, a key factor that prevents a mobile device from accessing multimedia content is that it does not have enough display real estate to render the content that is traditionally created for the desktop web client. Moreover, the wireless network typically has lower bandwidth compared to a wired network of the same time frame. Therefore, a transcoder is needed somewhere in the network to transform multimedia content to the appropriate form factor and bandwidth requirement. This paper introduces an extremely fast transcoder of such kind. Comparing to the previous methods, additional computation is saved while the quality of transcoding is maintained. This saving in computing resources maps into the benefit that more concurrent sessions can be supported on one transcoding device. This scalability is crucial for the wireless network to handle user requests that might be very intensive at times.
