Problems solved by technology

In this case, if the first user removes the disc from the disc drive, the recording reservation by the second user cannot be realized.
In addition, not only recording reservations cannot be made, but also because the CD recorder becomes inoperable, even if other equipment accesses the CD recorder through the network, an appropriate response cannot be obtained, which may cause a network failure.

no. 1 Embodiment approach

[0030] FIG. 1 is a block diagram showing the configuration of a video server system 300 of the present invention. The video server system 300 includes first servers 11 and 12 and a second server 10 . The first servers 11, 12 and the second server 10 each have an interface device connectable to the network 100, and can mutually transmit and receive data. In the present embodiment, the video server system 300 includes the first servers 11 and 12, but it only needs to include one or more first servers.

[0031] Each of the first servers 11 and 12 functions as a broadcast receiver for receiving broadcast programs. The first server 11 includes a tuner 11 , a timer 112 , and a reservation management unit 113 . The tuner 111 selectively receives broadcasts of a designated channel. In this embodiment, tuner 111 cannot receive two or more broadcasts at the same time. The timer 112 measures time. The reservation management unit 113 manages, through the tuner 111 , which channel's b...

no. 2 Embodiment approach

[0051] In the first embodiment, the recording rate of the program recorded by the user on the recording drive 4 is the same as the transfer rate of the program. In the video server system of this embodiment, programs can be recorded on a recording drive at a bit rate lower than the transfer rate of received broadcast programs, and the programs can be viewed at the original transfer rate as needed. For example, when the program is broadcasted in HD (High Definition) standard, and the recording drive 4 can only support the SD standard, but not the HD standard, or even if the recording drive supports the HD standard, because it is desired to record for a long time, etc. The reason is that this embodiment is suitable for recording at a bit rate lower than the HD standard.

[0052] Fig. 5 is a block diagram showing a second embodiment of the video server system according to the present invention. The video server system 310 includes a first server 13 and a second server 10 , and t...

Abstract

The invention is aimed to provide a video recorder which can record a broadcast program through a network without causing network failure or the like, maintaining an advantage of the interchangeability of an information recording medium. This video recorder connectable with the network is provided with a reservation management section which manages broadcast program reservation information, a recording drive which records on an interchangeable information recording medium and which records broadcast program data on the information recording medium, and a controller which controls the reservation management section and the recording drive. When the recording drive is loaded with the information recording medium, and such a setting that the recording drive records the broadcast program data is performed, the controller prohibits other apparatus from accessing the recording drive through the network.

Description

technical field [0001] The present invention relates to a video recorder equipped with a recording drive for recording on an exchangeable information recording medium and a video server system in which the video recorder is connected to a network. Background technique [0002] In recent years, an optical disc video recorder using a disc-shaped optical recording medium (hereinafter referred to as an optical disc) such as a recordable DVD has become popular as an image recording device replacing a video tape recorder. An optical disc has a planar data recording surface for recording digitized video information or audio information, and an optical head for recording and reproducing can access any position on the data recording surface within a few seconds. Therefore, even if a large amount of video information is recorded on the optical disc, arbitrary video information can be reproduced in a short time. In addition, since the optical disc as the recording medium can be exchan...
