Abstract

The communications terminal comprises: a playback device which playbacks content; a reading device which reads in access information recorded on a prescribed recording medium, the access information being necessary for downloading the content which can be played back by the playback device, via a network; a communications device which downloads via communications the content corresponding to the access information according to the access information read in; a storage device which stores the downloaded content, the storage device storing details of the access information in association with the content, the details of the access information being used in downloading the content; a judging device which judges whether or not the content corresponding to the read access information is present in the storage device, according to information which is stored in the storage device, when the access information is read in by the reading device; and a control device which controls the playback device, the reading device, the communications device, the storage device, and the judging device, wherein: if the judging device judges that the content is present in the storage device, the control device controls for acquiring the content corresponding to the access information read in from the storage device, and for playing back the content; and if the judging device judges that the content is not present in the storage device, the control device controls for downloading the content corresponding to the access information read in, and for playing back the content.

Claims

1. A communications terminal, comprising:

a playback device which playbacks content;

a reading device which reads in access information recorded on a prescribed recording medium, the access information being necessary for acquiring the content which can be played back by the playback device from a prescribed server via a network;

a content requesting device which requests the content corresponding to the read access information to the server;

a receiving device which receives metadata together with the content from the server, the metadata containing update control information including a content ID for the requested content;

a storage device which stores the received content and the metadata in a mutually associated condition; and

an update control device which controls for requesting updating of the content corresponding to the content ID to the server according to the update control information, for updating the new content requested updating, and for storing the new updated content which is received from the server by the receiving device,

wherein the access information includes the content ID and the update control device determines whether the content is stored in the storage device for playback by comparing the content ID of the access information with the metadata stored in the storage device, and

the update control device determines that the content is not stored in the storage device if the content ID of the read access information is not included in the metadata stored in the storage device, and controls the content requesting device to request the content corresponding to the content ID of the read access information to the server if the content is not stored in the storage device.

2. The communications terminal as defined in claim 1, wherein:

the update control information contains date/time of next update.

3. A playback control method, comprising the steps of:

configuring at least one processor to perform the functions of;

reading in access information recorded on a prescribed recording medium;

judging whether or not content corresponding to the access information is stored in a prescribed storage device;

acquiring the content and metadata via a network from a prescribed server, if the content corresponding to the read access information is not stored in the storage device when the access information is read in, the metadata containing update control information including a content ID for the content;

updating the content corresponding to the content ID stored in the storage device according to the metadata stored in the storage device in association with the content; and

playing back the content stored in the storage device,

wherein the access information includes the content ID,

the judging comprises determining whether the content is stored in the storage device for playback by comparing the content ID of the access information with the metadata stored in the storage device, and determining that the content is not stored in the storage device if the content ID of the read access information is not included in the metadata stored in the storage device, and

the acquiring the content comprises requesting device to request the content corresponding to the content ID of the read access information to the server if the content is not stored in the storage device.

4. A computer readable storage medium having embodied thereon a computer program for processing by a computer, the computer program comprising:

a first code segment for reading in access information recorded on a prescribed recording medium;

a second code segment for judging whether or not content corresponding to the access information is stored in a prescribed storage device;

a third code segment for acquiring the content and metadata via a network from a prescribed server, if the content corresponding to the read access information is not stored in the storage device when the access information is read in, the metadata containing update control information including a content ID for the content;

a fourth code segment for updating the content corresponding to the content ID stored in the storage device according to the metadata stored in the storage device in association with the content; and

a fifth code segment for playing back the content stored in the storage device,

wherein the access information includes the content ID,

the judging comprises determining whether the content is stored in the storage device for playback by comparing the content ID of the access information with the metadata stored in the storage device, and determining that the content is not stored in the storage device if the content ID of the read access information is not included in the metadata stored in the storage device, and

the acquiring the content comprises requesting device to request the content corresponding to the content ID of the read access information to the server if the content is not stored in the storage device.

5. A communications terminal, comprising:

a playback device which playbacks content;

a reading device which reads in access information recorded on a prescribed recording medium, the access information being necessary for acquiring the content which can be played back by the playback device from a prescribed server via a network;

a content requesting device which requests the content corresponding to the read access information to the server;

a receiving device which receives metadata together with the content from the server, the metadata containing update control information including a content ID for the requested content;

a storage device which stores the received content and the metadata in a mutually associated condition; and

an update control device which controls for requesting updating of the content corresponding to the content ID to the server according to the update control information, for updating the new content requested updating, and for storing the new updated content which is received from the server by the receiving device,

wherein the update control device determines that the content is stored in the storage device if the content ID of the read access information is included in the metadata stored in the storage device, and the update control device controls the playback device to playback the content if the update control device determines that the content is stored in the storage device.
