Abstract

Provided is a content reproduction device which enables a user watching or listening to a content on a given content reproduction device to discontinue the watching thereof or listening thereto and then easily resume the watching of the same content or listening thereto from a discontinued state on another content reproduction device. When reproduction of a content is discontinued, discontinued state information indicating a reproduction state of the content at a time point of the discontinuation is transmitted to a watching/listening history management server (20) and the discontinued state information stored in the watching/listening history management server (20) is received from the watching/listening history management server (20), and the reproduction of the content is started from a state determined based on the received discontinued state information.

Claims

1. A content reproduction device, which is to be connected to a watching/listening history management server, comprising:

content reproduction means for reproducing a content;

discontinued state information transmission means for transmitting, when reproduction of the content is discontinued, discontinued state information indicating a reproduction state of the content at a time point of the discontinuation to the watching/listening history management server; and

discontinued state information reception means for receiving the discontinued state information stored in the watching/listening history management server from the watching/listening history management server,

wherein the content reproduction means starts the reproduction of the content from a state determined based on the received discontinued state information.

2. The content reproduction device according to claim 1, wherein:

the discontinued state information transmission means transmits the discontinued state information to the watching/listening history management server in association with identification information on a user of the content reproduction device; and

the discontinued state information reception means receives the discontinued state information associated with the identification information on the user of the content reproduction device from the watching/listening history management server.

3. The content reproduction device according to claim 2, wherein:

the discontinued state information reception means receives a plurality of pieces of the discontinued state information, which are stored in the watching/listening history management server and which are common in the user and the content, from the watching/listening history management server; and

the content reproduction means starts the reproduction of the content from a state determined based on apiece of the discontinued state information selected from among the received plurality of pieces of the discontinued state information.

4. The content reproduction device according to claim 3, wherein the content reproduction means presents, to the user as options, a plurality of pieces of the discontinued state information selected from among the received plurality of pieces of the discontinued state information based on a predetermined selection condition, and starts the reproduction of the content from a state determined based on a piece of the discontinued state information selected from among the options presented to the user.

5. The content reproduction device according to claim 4, wherein:

the discontinued state information transmission means transmits the discontinued state information to the watching/listening history management server in association with identification information on the content reproduction device; and

the content reproduction means presents, as one of the options, each of a plurality of pieces of the discontinued state information associated with mutually different pieces of identification information on content reproduction devices among the received plurality of pieces of the discontinued state information.

6. The content reproduction device according to claim 4, wherein the content reproduction means selects, as one of the options, a piece of the discontinued state information corresponding to the reproduction of the content last executed by the content reproduction means, which is used as the predetermined selection condition.

7. The content reproduction device according to claim 4, wherein the content reproduction means selects, as one of the options, a piece of the discontinued state information corresponding to the reproduction of the content which is last executed, from among the received plurality of pieces of the discontinued state information, which is used as the predetermined selection condition.

8. The content reproduction device according to claim 4, wherein:

the content is time-series data that is sequentially reproduced from a starting position to an end position with a lapse of time; and

the content reproduction means selects, as one of the options, a piece of the discontinued state information indicating that the content was reproduced up to a position farthest from the starting position from among the received plurality of pieces of the discontinued state information, which is used as the predetermined selection condition.

9. A content reproduction system, comprising:

a plurality of content reproduction devices; and

a watching/listening history management server, wherein;

each of the plurality of content reproduction devices comprises;

content reproduction means for reproducing a content; and

discontinued state information transmission means for transmitting, when reproduction of the content is discontinued, discontinued state information indicating a reproduction state of the content at a time point of the discontinuation to the watching/listening history management server;

the watching/listening history management server comprises storage means for storing the discontinued state information received from the each of the plurality of content reproduction devices;

the each of the plurality of content reproduction devices further comprises discontinued state information reception means for receiving the discontinued state information from the watching/listening history management server; and

the content reproduction means starts the reproduction of the content from a state determined based on the received discontinued state information.

10. A content reproduction method, which uses a content reproduction device to be connected to a watching/listening history management server, comprising the steps of:

reproducing a content;

transmitting, when reproduction of the content is discontinued, discontinued state information indicating a reproduction state of the content at a time point of the discontinuation to the watching/listening history management server; and

receiving the discontinued state information stored in the watching/listening history management server from the watching/listening history management server,

wherein the step of reproducing a content comprises starting the reproduction of the content from a state determined based on the received discontinued state information.

11. A computer-readable information storage medium having a program stored thereon for causing a computer to be connected to a watching/listening history management server to function as:

content reproduction means for reproducing a content;

discontinued state information transmission means for transmitting, when reproduction of the content is discontinued, discontinued state information indicating a reproduction state of the content at a time point of the discontinuation to the watching/listening history management server; and

discontinued state information reception means for receiving the discontinued state information stored in the watching/listening history management server from the watching/listening history management server,

wherein the content reproduction means starts the reproduction of the content from a state determined based on the received discontinued state information.
