AI Technical Summary

Problems solved by technology

However, in order to realize both functions, the scale of the program becomes very large and the processing is complicated, so it takes a lot of time to verify the operation of the program.
In addition, the control of the entire disc recorder including the processing of this program is also complicated and difficult to manage.
Therefore there is no effective solution

Embodiment Construction

[0053] Embodiments of the data processing device of the present invention will be described below with reference to the drawings. In the embodiment, the data processing device will be described as an optical disk recorder.

[0054] FIG. 1 shows the configuration of a system formed by an optical disk recorder 100 of this embodiment and other devices. The optical disk video recorder 100 (hereinafter referred to as "recorder 100") has a recording function for recording a data stream of moving images related to video and audio of a broadcast program on a Blu-ray Disc (Blu-ray Disc; BD) 114. In addition, the video recorder 100 It also has the reproduction function of reading out the data stream recorded in the BD114 and reproducing the dynamic image. Also shown in Fig. 1 are other machines that can be associated with the video recording function and the reproduction function of the video recorder 100. The video recording function and the reproduction function of the video recorder ...

Abstract

A data structure which can efficiently manage a moving picture and a still picture, and an apparatus which performs recording / reproduction by using such data structure are provided. A data processor is provided with a drive device for writing one or more still picture files in a hierarchy of a still picture folder of a recording medium or lower. The data processor is also provided with a control part which generates file specifying information for specifying a storing position of each still picture file in the hierarchy, generates identifying information for uniquely identifying each still picture file, and generates a table which associatesthe file specifying information with the identifying information. The drive device writes the generated table in the recording medium as a table file.

Description

technical field [0001] The present invention relates to a technique for recording still image data in a recording medium capable of recording moving image data and managing the data Background technique [0002] In recent years, optical disc video recorders capable of recording and saving digital data of video and audio on optical discs such as DVDs have become popular. The object to be recorded is, for example, a data stream of a broadcast program, or a data stream of video and audio captured by a camcorder or the like. The user can record the recorded data on a DVD in a randomly accessible state and save it. [0003] The CD recorder can not only record the data stream of moving images in DVD, but also record still image data. When a user shoots a still image using a digital camera or a camcorder, the still image data is recorded in a semiconductor memory card loaded therein. Some optical disk recorders are provided with a slot for loading such a semiconductor memory car...
