Embodiment Construction

[0043] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0044] figure 1 A configuration example of a system including a video recording / playback device 104, a broadcasting station 101 supplying content to the video recording / playback device, and a VoD (Video on Demand) server 102 is shown. For example, content is a program including images and sound.

[0045] 101 denotes a broadcasting station that mainly distributes content through broadcast waves, and 102 denotes a VoD server that transmits content via a network. The broadcast station 101 and the VoD server 102 may be the same business entity, or the VoD server 102 may be present in the broadcast station 101 . 103 is a broadband network, and the VoD server 102 is connected to the video playback device 104 .

[0046] The video playback device 104 is an HDD / optical disk recorder, a PC, a mobile phone, or the like. It is not necessary to have two functions of video record...

Abstract

A user can view a necessary content while a memory owned by the user does not need to have a large capacity. A problem with a copyright related to content is prevented. A recorder has a recording section and a VoD section. The recording section records content. The VoD section compares the content recorded by the recording section with content provided through a video-on-demand service, and removes the content recorded by the recording section based on the comparison. The recorder also has a receiving section and a reproduction content selector. The receiving section receives the content provided through the video-on-demand service. The reproduction content selector allows the receiving section to receive and reproduce the content provided through the video-on-demand service when the reproduction content selector receives an instruction for reproduction of the content removed by the VoD section.

Description

technical field [0001] The present invention relates to a video recording device and a content management method, in particular to a video recording device and a content management method responding to video on demand. Background technique [0002] In the video playback device, there is an upper limit to the amount of content that can be recorded. Several explorations have been made with this upper bound in mind. For example, in Patent Documents 1 to 3, when the number of empty areas in the recording area decreases, the recorded content can be re-encoded to reduce the recording bit rate and increase the empty area. In Patent Document 4, a plurality of devices coordinate and control so as not to repeatedly record the same content, and it is possible to combine calculations and effectively use the recording areas of the devices performing coordination. In Patent Documents 5 to 7, recording is instructed to a device such as a server (suba) through remote operation, and conten...
