Embodiment Construction

[0022] An embodiment of the present invention will now be described with reference to the accompanying drawings.

[0023] FIG. 1 shows the structure of a video recorder 11 according to an embodiment of the present invention. The video recorder 11 is a video data recording / reproducing device capable of digitally recording and reproducing video data such as various TV broadcast programs.

[0024] The video recorder 11 has a network function for connection to a local area network (LAN). The video recorder 11 may communicate with a server 15 via a network, such as the Internet 14 . The server 15 is an external unit in which video data recorded in the video recorder 11 is to be saved.

[0025] As shown in Figure 1, the video recorder 11 comprises a central processing unit (CPU) 111, a memory 112, a network controller 113, a user interface unit 114, a TV tuner 115, an encoder 116, a hard disk drive 117, a decoder 118, an audio - Video (AV) output unit 119 .

[0026] The CPU 111 ...

Abstract

A video data recording / reproducing apparatus includes an input device (115), a data storage unit (117) that stores the video data item input by the input device (115), a communication unit (113) that executes communicates with an external unit (15) via a network (14), a unit that moves one of a plurality of video data items stored in the data storage unit (117) to the external unit (15), a unit that reproduces to-be-reproduced video data item from the data storage unit (117) if the to-be-reproduced video data item is stored in the data storage unit (117), and a unit that executes a streaming process to reproduce a stream of the to-be-reproduced video data item that is transferred from the external unit (15) while the stream of the to-be-reproduced video data item is being received by the communication unit (113), if the to-be-reproduced video data item is stored in the external unit (15).

Description

technical field [0001] The present invention relates to a video data recording / reproducing device for recording and reproducing video data, and a video data management method for the device. Background technique [0002] In recent years, various video data recording / reproducing apparatuses capable of recording and reproducing video data such as television broadcast programs have been developed. In this type of video data recording / reproducing apparatus, a hard disk drive (HDD) has started to be used as a video data recording medium instead of a conventional video tape. [0003] If a broadcast program is recorded on a hard disk drive, it is necessary to locate the beginning of the recorded broadcast program at high speed. In addition, by recording broadcast programs on a hard disk drive, a so-called post-recorded viewing function (also called a time-slip function) can be realized. The post-recorded viewing function is a function for reproducing a recorded broadcast program ...
