Abstract: The present invention provides a method for forwarding frames between Ethernet network nodes in which an output queue is provided for storing frames to be forwarded in the same direction, and more than one frame stored in the output queue are combined into a single frame, and the combined frame is then transmitted to the output port corresponding to that direction. With this configuration, packets encapsulated into a plurality of frames are stored in the output queue during transmission of the previous frames in the same direction or during their inter-frame gaps, and then combined into one packet, the combined packet being encapsulated into one frame to be transmitted. Accordingly, the amount of data that can be transmitted during a certain time period is increased by the amount equivalent to the reduced number of inter-frame gaps compared to when packets encapsulated into a plurality of frames are individually transmitted, thereby achieving more efficient frame forwarding.

Abstract: A video processing system which realizes high efficiency and improved service quality in video production, including high-speed extraction of scenes related to a particular subject and compilation of a personalized video product. Video recording units are placed along a given course, each of which stores video of moving objects that is captured by a fixed camera, together with time stamps that indicate at what time each part of the video was taken. At checkpoints on the course, time measurement units measure checkpoint passage time of every passing moving object and store checkpoint time records including the measured checkpoint passage times and identifiers of individual moving objects. A video authoring unit searches the stored video data to find and extract scenes of a particular moving object, using the checkpoint time records in association with time stamps in the video data, and compiles the extracted scenes into a personalized video product.
