The shooting group may be, for example, the 'A team' group, in which case all the shooting equipment attached to the helmet of the team A players may be included in the shooting group.
According to an embodiment of the present invention, when determining whether or not the plurality of photographing apparatuses are photographing apparatuses included in a predetermined photographing group, information about photographing apparatuses is previously registered in the server as the same group name (e.g., group A) , The photographing equipment can be determined as the photographing equipment included in the predetermined photographing group. That is, for example, the server may store a group information table, and the table may include an information item of the photographing apparatuses to be included and stored.
In addition, the server may update the pre-stored photographing equipment information when there is a difference between the information about the received photographing equipment and the photographing equipment information previously stored in the server. In other words, the server can always keep the imaging equipment information up-to-date.
On the other hand, according to the embodiment, when the information about the photographing equipment is not registered in the server with the same group name, the photographing equipment can be determined as the photographing equipment not included in the predetermined photographing group. In this case, it is possible to create a new new group on the basis of the photographing equipment information of the photographing equipment, and to select the photographing equipment as a master terminal, for the terminal determined not to be included in the photographing group. That is, a new photographing group can be constituted mainly by photographing equipment not included in the photographing group. In addition, the server may generate a group table for the created group, and may store, in the group table, information about the synchronization period from the information about the master photographing equipment. Thus, a new group is created and information about the new group can be stored and utilized in the server.
According to the embodiment, when the group information request signal is transmitted from another photographing equipment not included in the photographing group to the server, the server can transmit the information about the group to the photographing equipment that transmitted the request signal have. That is, the photographing device having no preset photographing group can request the group information from the server, and transmit the registration request signal to the server with reference to the group information. In addition, when the subscription request signal is received, the master photographing device requests a photographing group registration permission signal of another photographing device. In response to this, the master photographing equipment can determine whether or not to join based on a predetermined criterion, and then transmit a subscription permission signal or an unsubscribe signal to the server.
Meanwhile, all the photographing equipments themselves can form a new photographing group and function as a new master terminal. To this end, a request signal for forming a new group is transmitted to the server and information about a new group is transmitted to another terminal May lead to subscription. In addition, the terminal desiring to belong to the group may request information on the groups formed up to now in the server, or may select a group to be subscribed and become a slave terminal.
According to the embodiment, when the subscription request signal is transmitted, the master photographing apparatus displays a related menu on the display unit and receives a subscription permission signal or a subscription permission signal from the user through the user interface unit, Lt; / RTI >
According to another embodiment of the present invention, any one of the plurality of photographing equipments has a master mode of On, and the other photographing equipments have a master mode of Off, If the subscription request signal is transmitted, the subscription permission signal is automatically generated and transmitted.
In addition, when the subscription permission signal of the photographing equipment is received from the master photographing equipment, the server includes a photographing equipment that transmits the subscription request signal to the generated group as a slave terminal to configure a photographing group . Accordingly, the digital image photographed by the master photographic equipment and the slave photographic equipment can be marked in the master photographic equipment and the slave photographic equipment according to the marking cycle criterion of the generated group. Thus, synchronization can be performed based on this marking information.
According to an embodiment of the present invention, when a synchronization termination signal is received from the master photographing equipment, the server may transmit the synchronization termination signal to each slave photographing equipment so as to perform a synchronization operation.
Next, the server transmits synchronization information and a control signal to the photographing equipments determined to be included when it is determined that the photographing group is included in the photographing group. According to an embodiment of the present invention, in transmitting the synchronization information and the control signal, the synchronization period information (e.g., marking every 5 seconds) and the synchronization information transmission method information (Photographing start / stop / end signal) and photographing information (frame number, color, size information per second) including at least one of the presence / absence of the mark . According to an embodiment, the synchronization information transfer method information may include information on whether to directly mark an image photographed by the photographing equipment, or whether to store the marking information as separate marking information.
According to an exemplary embodiment of the present invention, the step of transmitting the synchronization information and the control signal to the server may include transmitting synchronization period information to the imaging devices determined to be included in the imaging group, (ACK) signal from the photographing equipment which has transmitted the photographing start signal to the photographing equipment when the photographing preparation of the photographing equipment is completed have. That is, the server can control the start of shooting.
Next, an external image is photographed through the photographing equipment. The photographing equipment encodes the photographed image into a digital image, and performs marking on the photographed image based on the received synchronization information to generate marking information. In addition, the imaging equipment may transmit the encoded image and marking information to the server. According to an embodiment, the marking can be performed on the encoded image and can be encoded after the marking is performed. However, information on such a sequence may be included in the image so that it can be recognized by a decoder.
According to an embodiment of the present invention, in performing the marking, the photographing equipment performs marking on the photographed image according to a predetermined period based on synchronization information received from the server. According to the embodiment, the photographing equipment can transmit the mark information to the server according to a predetermined period based on the information received from the server.
According to the embodiment, in performing the marking, the photographing equipment may store the marking information in the form of dummy data, for example, information about a certain synchronization, information about time, information about the image itself Inserted into the video material, stored in the imaging equipment, and transmitted to the server.
According to another embodiment of the present invention, in performing the marking, the photographing equipment may store mark information in a storage unit of the photographing equipment according to a predetermined period based on information received from the server, When the encoding is completed in the photographing equipment, the completed encoded image and the mark information stored until the completion time can be transmitted to the server.
That is, according to the embodiment, the marking information can be immediately transmitted to the server, and according to another embodiment, after the marking information is accumulated to some extent, the accumulated marking information can be transmitted to the server.
