Abstract: This invention provides an adaptive transcoder which streams predictive coded video data over variable bandwidth networks and to devices having varying processing capabilities. The invention dynamically and continuously determines an available network bandwidth and a client device's processing capabilities. This invention uses bit stream transcoding of video data to reduce the bandwidth required to stream the video. Certain frames of a bit stream are replaced with Pseudo-P frames according to the results of rate control feedback and frame ranking. The invention thus transmits a single MPEG stream to multiple devices having varying capabilities and does not add redundancy into the network.

Abstract: This invention provides a system and method to reduce rectangular graph images. According to the invention, the main graph and axis portions of a rectangular graph image are reduced separately such that readability and clarity of the entire graph image is maintained. The axes of the graph are reduced according to a position of the text values included on the axes of the image. The system may be accessed over a network by display devices when reducing for display images that include rectangular graphs.
