Method and apparatus for asynchronous communication over a standard data bus using a plurality of data descriptors having still image data written therein

摘要

Data having a small amount of data, such as still image data, is transmitted by using asynchronous packets. A source apparatus writes data which can be selected from a data source block into a data descriptor within a memory. Then, the source apparatus transmits the data read from the data descriptor to a receiver apparatus by using asynchronous packets. The receiver apparatus can also write data which can be selected from the data source block into a data descriptor within a memory.
