<P>PROBLEM TO BE SOLVED: To solve the problem that an I/O processing load of stream data to a storage device becomes large when a plurality of streams such as W recording of digital broadcast and recording and playback simultaneous processing are simultaneously treated in a digital device having the storage device. <P>SOLUTION: The storage device is characterized by having: a data storage part 103 for storing data including the stream data; a host I/F part 102 for inputting/outputting various kinds of data and control commands; a buffer memory 104 for temporarily buffering the data; a clock management part 105 for managing a clock counter value; and a control part 110 for interpreting various commands such as a playback instruction (directions (forward direction, backward direction), speed (nX), playback time (place), etc.) provided from a host means, correcting the clock counter value based on an input clock synchronizing signal, reading the stream data from the data storage part, and autonomously transferring the stream data to the host means while referring to the clock counter value. <P>COPYRIGHT: (C)2009,JPO&INPIT |
