JP5094704B2 - Content sharing system and content sharing method - Google Patents

Description

  The present invention relates to a content distribution system, a content distribution server, a content upload terminal, a content viewing terminal, and a content sharing method via a network.

  In recent years, with the increase in capacity of network lines and the increase in capacity of hard disks, IP television (IPTV) services for distributing contents such as television programs and movies through an IP (Internet Protocol) network are being realized.

  In a system for exchanging images with each other through these networks, it is difficult to specify a photographer who is present at the same place from parameters acquired at the time of photographing. It is difficult to share simple images. In Patent Document 1, in order to solve the above problems, images of various angles, timings, and the like are acquired by sharing corresponding images by wireless communication such as bluetooth (registered trademark) between the photographing devices at the time of photographing. Is possible.

FIG. 4 is a diagram showing an example of content additional information 1201 transmitted from the mobile terminal 902 to the shared server 905. This content additional information 1201 is content management information, and each parameter is set at the timing of a user operation.
In FIG. 4, reference numeral 1201 indicates content additional information, reference numeral 1202 indicates a content ID, reference numeral 1203 indicates a shooting date, reference numeral 1204 indicates a shooting start time, reference numeral 1205 indicates a shooting end time, reference numeral 1206 indicates position information, and reference numeral 1207 indicates a terminal. ID, reference numeral 1208 indicates the related device ID.

  Content additional information 1201 is management information for each content managed in the mobile terminal, and includes location information and shooting time around the mobile terminal at the time of co-shooting, and is sent as a piece of information when the content file size is finalized Or, it is a set of information to be transmitted to the shared server at the timing of each user operation.

Details of the content additional information 1201 will be described below.
The content ID 1202 is a unique ID in the portable terminal 902 that manages the content recorded from when the recording button is pressed to when recording is stopped.

The shooting date 1203 is the date when the recording button is pressed. The shooting start time 1204 is the time (HH: MM: SS) when the recording button of the portable terminal 902 is pressed.
The shooting end time 1205 is the time (HH: MM: SS) when the first recording is stopped after the recording button is pressed.

  When the mobile terminal 902 has a GPS function, the location information 1206 acquires GPS when the recording button is pressed, and the location information is recorded. When the mobile terminal 902 does not have a GPS function, the position information of the public wireless LAN is acquired and the data is given in units of DMS degrees minutes / seconds or degrees degrees.

  The terminal ID (1207) is a unique ID on the network that is assigned by the shared server when registering a device to register the mobile terminal 902 for MAC address.

  The related device ID (1208) is a unique ID for each cluster that identifies a cluster of an ad hoc network that uses wireless in the nearby mobile terminal 902 when the recording button of the mobile terminal 902 is pressed, for example, the MAC address of the cluster head It is.

Next, the related device ID (1208) will be described in detail.
At the timing when the recording button of the portable terminal 902 is pressed, a nearby portable terminal 902 is searched using wireless communication installed in the portable terminal 902. When the wireless LAN uses the ad hoc mode, it is possible to search for N nearby mobile terminals 902 to form a cluster. N can be set by each device, but it is desirable to set the number corresponding to the processing capability in the mobile terminal 902 so that traffic due to routing of the ad hoc network does not cause a load on the network bandwidth. In the cluster, the portable terminal 902 that first presses the recording button becomes the cluster head, and the cluster is constructed. Each node acquires the ID of the cluster head and registers it in the related device ID 1208.

  The cluster relationship is released at the timing when the recording is stopped, but a new cluster is formed when the next recording button is pressed. Since the cluster head ID registered in the related device ID 1208 needs to be unique in each cluster, it needs to be unique on the network such as the MAC address of the cluster head.

  Since it is difficult to send content to the shared server 905 while a cluster is configured, the mobile terminal 902 is equipped with media such as an SD card or flash that can store more than a dozen content. It is desirable to do. When the mobile terminal 902 is equipped with storage, the content and content additional information 1201 are uploaded to the shared server 905 when the communication bandwidth is good.

The terminal ID (1404) is an ID for associating the user-owned content reception / playback apparatus 901 with the portable terminal 902.

  FIG. 6 is a diagram showing a terminal registration sequence. This is a sequence for registering that the portable terminal and the content reception / playback apparatus are owned by the same user when using the service of this system.
