Abstract
A video recording device for recording a plurality of sets of video information including a plurality of sets of character information is provided. An ADC sequentially receives the plurality of sets of video information at a receive frequency. A character extracting unit extracts the plurality of sets of character information from the plurality of sets of video information. A video recording controlling unit outputs the plurality of sets of video information one at a time at a fixed output frequency without depending on the receive frequency, wherein the video recording controlling unit skips a set of video information or outputs an once-outputted set of video information when there is a discrepancy between the receive frequency and the output frequency. A character information recording controlling unit outputs the plurality of sets of character information one at a time at the output frequency. A recording unit records the outputted plurality of sets of video information and the outputted plurality of sets of video information, into the recording medium. Here, under a predetermined condition, the character information recording controlling unit judges whether a value included in …
