0 is transmitted to the server 101, and the network control circuit 108 receives the service content provided from the server 101 in step 308. From the service content received at step 308 or being received, the data received by the system control circuit 104 as appropriate to the reproduction control circuit 107 at step 309 is sent to reproduce the service content.

In FIG. 3 (2), in step 310, the playback device 100 is in step 307.
The server 101 receives the content ID 200 transmitted from the server 101.

Next, in step 311, the server 101 selects service content corresponding to the content ID 200, and reads or generates information for transmission to the playback device 100. Thereafter, in step 312, the server 101 transmits the service content to the playback device 100.

As described above, the user can connect to the service providing site without performing complicated operations such as inputting a connection destination URL in order to obtain service content. Further, the content providing side can set and provide a URL of a dedicated service providing site for each content, and can easily provide an easy-to-use service specialized for the user who purchased the content. For example, even if the content being played back by the user is old, it is possible to provide service content that matches the time of playback and the type of content, and users can always provide service content that matches the times and trends. Can be used to contribute to business development on the content provider side and improved usability on the user side.

In this embodiment, not only the content ID recorded on the recording medium but also additional information such as a URL (Uniform Resource Locator) for connecting to the server is read, and the function to connect to the server and the content ID are transmitted. By having the function to
It becomes easy for the content providing side to determine and provide service information suitable for the user.

Next, a second embodiment will be described. In the present embodiment, a processing flow when content is played back on the playback device and when a server is connected will be described.

In FIG. 3A, in step 300, the DVD control circuit 105 performs DVD

In step 303, the database control circuit 109 performs registration processing in the database. Thereafter, in step 304, normal reproduction processing is performed.

Thereafter, the processing after step 304 is the same as that in the first embodiment, and a description thereof will be omitted.

The content ID registered in the management database is not limited to the content ID of the content read from the recording medium, and the content ID of the content acquired via a network or the like may be registered. Moreover, it is good also as a structure which a user registers content ID.

In this way, it is possible to register more content that the user has already auditioned or already owned.

Further, in the present embodiment, when the playback device transmits the content ID 200 to the server, the playback device transmits another content I registered in the management database.
A configuration may be adopted in which D is transmitted to the server.

Then, the server 101 also selects, reads or generates service content related to the other content ID, and transmits it to the playback device. This is a configuration in which a plurality of content IDs are transmitted to the server, and the content ID 200 of the content of the mounted recording medium may not be distinguished from other content IDs.

With this configuration, more service content can be transmitted from the server, and the playback device can receive it.

In addition, the server 101 selects service content corresponding to the content ID 200, and searches for a correspondence relationship between the other content ID and the selected service content before transmitting the selected service content to the playback device. To do. If the service content related to the content with the other content ID is to be transmitted, it is determined that the service content is the service content of the content with the content ID already registered in the playback device. Then, the service content is not transmitted to the playback device.

For example, the first movie of a movie is recorded on the DVD 106, and the content ID 20
Assume that 0 indicates the first movie. On the other hand, it is assumed that the content ID of the second movie has already been registered in the management database. In this case, the playback apparatus is configured to transmit not only the content ID 200 but also the content ID of the second movie to the server.

Then, when the server 101 transmits the service content for the second movie as the service content corresponding to the content ID 200, the playback device 100 has already registered the content ID of the second movie. The service content regarding the first movie is not transmitted to the playback apparatus 100.

As a result, it is possible to reduce the server from transmitting the service content of the content with the content ID already registered in the playback device to the playback device.

As described above, the user can connect to the service providing site without performing complicated operations such as inputting a connection destination URL in order to obtain service content. In addition, the content provider can set and provide a URL for a dedicated service provider site for each content, and can easily provide an easy-to-use service specialized for users who have purchased the content. In addition, it is possible to provide user-friendly service content by utilizing content information owned by the user. This may be provided as a server function or a playback device function.

FIG. 4 is a screen example showing a service screen at the time of connection between a playback apparatus and a server which is an embodiment to which the present invention is applied.

In FIG. 4, reference numeral 400 shows an example of a content purchase service screen provided via a network. 401 indicates the title of the service screen, and a title that directly represents the service content of the screen is displayed. Here, since it is a content purchase service screen, “content list” is displayed. Reference numeral 402 denotes a button for shifting to a screen for purchasing an item selected by the user. Reference numeral 403 denotes a list of titles related to content provided by the service provider. Reference numeral 404 denotes an operation explanation display on the currently displayed screen. Reference numeral 405 denotes an icon display indicating that the title is already owned by the user.

Note that the content already owned by the user may not be displayed as a title, or may not be received from the server.

Reference numerals 406 and 407 denote check boxes for setting a title to be purchased by the user. 406 indicates that it is not a purchase target, and 407 indicates that it is a purchase target.

In this way, by managing a plurality of content IDs in the database, the present invention is the first for any service site to be a closed service that was conventionally available only for sites used in the past. Even when using it,
It will be available with a user-friendly UI for the above users. Further, the content providing side can also provide a service or the like for presenting recommended titles according to tastes to users who use for the first time.

In the present embodiment, the configuration in which the playback apparatus registers the management database has been described. However, the same effect can be obtained when the server registers the management database.

As described above, according to the present embodiment, not only the content ID recorded on the DVD but also a function of reading additional information such as a URL for connecting to the server, connecting to the server, and a function of transmitting the content ID As a result, the content providing side can easily determine and provide service information suitable for the user.
