ABSTRACT:
A computing system connected to storage medium and one or more rendering devices identifies and processes only selected frames of data that are stored on the storage medium, thereby reducing the resources and bandwidth is required to process and transmit the data to the rendering device(s) at a desired playback. The computing system has various modes for selecting the frames to be processed and transmitted. In one mode, all frames are selected. In another mode, only the key frames are selected. In yet other modes, only certain key frames are selected. Upon selecting the frames to be transmitted to the rendering device(s), the time stamps assigned to the selected frames are scaled so that the selected frames will be displayed for an appropriate duration of time that corresponds with the desired playback rate.
