This present invention includes a method and an apparatus for receiving
motion video, a method and a system for transmitting motion video, and
software to implement the methods and to program the system and the
apparatus. The method for receiving motion video includes receiving
motion video data at a wireless from a motion video server via a wireless
interface, displaying the motion video on a video display on the wireless
terminal, and transmitting to the motion video server via the wireless
interface display control commands to alter the presentation
characteristics of received motion video. If for instance the display
control command instructs the motion video server to increase the speed
of the motion depicted in the video presentation, the motion video server
may filter out any audio data and reduce the number of video image frames
transmitted to the wireless terminal. The method for transmitting motion
video includes receiving motion video data from a motion video server,
transmitting the motion video data to a wireless terminal via a wireless
interface, receiving from the wireless terminal via the wireless
interface display control commands to alter the presentation
characteristics of motion video, and transmitting the display control
commands to the motion video server. The invention may be implemented,
for example, in an apparatus such as a wireless telephone and in a system
such as a digital wireless telephony network.
