Abstract:
A video recording device for recording a plurality of sets of video information that include a plurality of sets of character information, into a recording medium, comprising:a receiving unit operable to sequentially receive the plurality of sets of video information at a receive frequency which may vary; an extracting unit operable to sequentially extract the plurality of sets of character information from the received plurality of sets of video information; a video outputting unit operable to output the received plurality of sets of video information one at a time at a fixed output frequency which does not depend on the receive frequency, wherein when there is a frequency discrepancy between the output frequency and the receive frequency, the video outputting unit (1) skips a set of video information or (2) outputs a set of video information which was once outputted, again; a character outputting unit operable to output the extracted plurality of sets of character information one at a time at the output frequency, in the extracted order; a recording unit operable to record the outputted plurality of sets of video information and the outputted plurality of sets of character information in combination, into the recording medium in the outputted order; and an abandoning unit operable to, whenever a predetermined condition is met, (a) judge whether a value included in a set of character information extracted by the extracting unit is null, (b) abandon the set of character information whose value is judged as being null, and (c) instruct the character outputting unit to skip the abandoned set of character information and instead output a set of character information immediately following the abandoned set of character information.
