<p><P>PROBLEM TO BE SOLVED: To match the transmission rate and phase of an output from an active signal processing unit with the transmission rate and phase of an output from a reserve signal processing unit in a signal conversion apparatus including two kinds of active and reserve signal processing units for applying signal processing of digital compression processing, such as MPEG compression to a video signal. <P>SOLUTION: The signal conversion apparatus is provided with: active and reserve storage units which are provided between an active encoder and a switching unit and between a reserve encoder and the switching unit, and write and read video data generated by compressing a video signal, an invalid data storage unit for reading invalid data; and a control unit which reads each of video data at a higher transfer rate than that of writing and performs control to read the invalid data in place of video data stored in the storage units if the video data become less than a predetermined amount. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
