Abstract:
1. A video processing device for recording, into a recording medium providing recording and reproduction, recording information including a compression-encoded video data and for reproducing the recording information recorded in the recording medium, comprising: a camera unit for supplying a video data to be recorded in the recording medium; an encoder for generating a compressed video data by compressing and encoding the video data from the camera unit; a system control unit for recording, into the recording medium, the compressed video data as a video file that is supplied from the encoder during a recording period from a recording start time to a recording end time and for recording, into the recording medium, an additional data as an index file that is information related to the compressed video data recorded in the recording medium, and for reproducing, from the video file recorded in the recording medium, the compressed video data and for reading the additional data from the index file; and an input unit for accepting a recording start instruction and a recording end instruction, wherein the system control unit records before accepting the recording start instruction, into the recording medium, the additional data recorded in the index file, the additional data composed of additional data regarding the compressed video data recorded during the recording period and another additional data including a time code value showing a time at which the recording of a compressed video data to be recorded next is started; wherein the system control unit reads, when starting to record to the recording medium after accepting the recording start instruction, the additional data recorded in the index file and recognizes a time code value showing a recording start time of a to-be-recorded-next compressed video data included in the additional data as a time code value showing the time of a frame at which the compressed video data is started; a continuousness detection unit for detecting a continuousness of the time codes in every frame from a video frame corresponding to the recording start instruction to a video frame corresponding to the recording end instruction; wherein the system control unit records, when recording the compressed video data, an information showing the continuousness of all time code values within the recording period detected by the continuousness detection unit into the index file, associating with the compressed video data; and wherein the additional data recorded in the index file is additional data regarding the compressed video data recorded during the recording period that includes a time required for a video shooting, information showing continuousness of time codes, and the time code value showing the recording start time of the recording period.
