Embodiment Construction

[0056] Now, a video recording / reproducing device according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0057] Fig. 8 shows an example configuration of a video recording / reproducing device. Referring to FIG. 8 , CPU 1 controls driver 2 via CPU bus 16 . The CPU 1 reads out a control program stored in a recording medium 3 such as a magnetic disk, optical disk, magneto-optical disk, or semiconductor memory. The CPU 1 controls the activation and deactivation of the operations of the components of the video recording / reproducing apparatus according to programs and based on information on user operations which are input from the operation input unit 4 via the CPU bus 5 . Specifically, the CPU 1 controls the information recording medium interface (I / F) 11 via the CPU bus 5, thereby controlling writing or reading of MPEG stream data and the like to or from the information recording medium 12.

[0058] The operation input ...

Abstract

In a recording apparatus such as a video camera or a hard disk recorder, the amount of GOP data is adjusted. To an MPEG stream output from a video encoder / decoder, padding data is added by a buffer controller. Accordingly, each GOP is recorded with the beginning thereof coinciding with a cluster boundary.

Description

[0001] This application is a divisional application of an invention patent application with a filing date of August 20, 2003, an application number of 03154588.2, and an invention title of "recording device and method, recording medium, and program". technical field [0002] The present invention relates to a recording device and method, a recording medium, and a program. More specifically, the present invention relates to, for example, a recording apparatus and method, a recording medium, and a program suitable for recording such as a Motion Picture Experts Group (MPEG) program stream or an MPEG video element stream on an information recording medium. (video elementary stream) streaming data. Background technique [0003] As a format for recording data on or reproducing data from an information recording medium such as a hard disk, a file allocation table (FAT) file system is known. A personal computer with an operating system (OS) such as MS-DOS or Windows(R) installed th...
