Abstract:
1. A video and audio data converter comprising: a first video and audio input/output section inputting and outputting first video and audio data; a second video and audio input/output section inputting and outputting second video and audio data; a video and audio data conversion section having a first input/output data control section, a second input/output data control section, and a timing generation section; a data storage section temporarily storing data input and output to said video and audio data conversion section; and an interface control section controlling an interface in order to input/output data between said data storage section and external storage means, wherein said first input/output data control section comprises: said second input/output data control section comprises: said timing generation section is configured so as to generate timing signals each representing a timing of a video data period, a timing of an audio data period, and a timing of a video or audio control information period of the video and audio data; and said video and audio data conversion section is configured so as to directly replace data of video and audio data input to and output from said first input/output data control section with data of video and audio data input to and output from said second input/output data control section in synchronism with the timing signals generated by said timing generation section, and performing insert edit processing.
