Abstract: In a video distribution apparatus, a memory caches segments of video data into which video data received from a communication network is sectioned on a basis of a predetermined unit and stores video identifying information of the segments of video data. A distribution controller derives, upon receipt of a cache distribution request from the network, video identifying information contained in a cache distribution request. A relay controller obtains segments of video data associated with the video identifying information from the memory to transfer the obtained segments of video data to a requester at a transfer rate defined on the segments of video data in the vicinity of a source of the video data. The video can be distributed at a transfer rate close to a transfer rate defined by a content distribution server while the video traffic can be diminished.

Abstract: An imaging system in which, if image data of variable resolutions is to be handled in keeping with the increasing resolution of the image data, the processing is executed efficiently without lowering the processing capability of the respective circuits. A memory controller time-divisionally transmits an acknowledge signal to the respective circuits within a range of the bandwidth limitation of an image data bus in which image data can be furnished to the respective circuits, and manages control so that the respective circuits will execute the pre-set processing. The memory controller has access to data in the respective circuits in real-time to cause image data to be written from the respective circuits to the image memory or to be read out from the image memory and sent to the respective circuits.

Abstract: In an imaging apparatus, an image is to be displayed in real-time on a finder. In the finder mode, a CCD interface 21a thins out horizontal components of image data supplied from an image generating unit 10 to one-third and also effects gamma correction etc to send the resulting image data to a camera DSP 21c. The camera DSP 21c effects data conversion and resolution conversion on the image data resulting from the thinning to convert the data into Y, Cb and Cr image data which is routed to a memory controller 22. The memory controller 22 writes the image data in the image memory 32 and reads out the data from the memory controller 22 to route the read-out data over an image data bus 33 to an NTSC/PAL encoder 23. The NTSC/PAL encoder 23 converts the image data in resolution and further converts the image data into data of the NTSC or PAL system to route the resulting data to a finder.
