Abstract
A method of multiplexed data reading and visual search, in which each video program is divided into a plurality of video data groups which are stored in a prescribed order among the memory devices, and m memory control units are connected with mxn input/output channels selectively and sequentially in units of time-slots such that each memory control unit is connected with each of input/output channel at least once within a prescribed period. Then, the reading operations of the video data groups stored in the memory devices are carried out by making accesses from m memory control units in parallel at each time-slot. Also, the visual search operations are carried out by abandoning a time-slot allocated to one input/output channel in a next small period when a request for changing a current playback mode to a new playback mode is received from a terminal in a current small period, allocating a new time-slot at which a next video data group to be accessed in the next small period according to the new playback mode is accessible to that input/output channel in the next small period, and reading and buffering the next video data group by using the new time-slot in the next small period.
