Definitions

  • Patent Document 1 describes an information provision system in which a complementary music file is downloaded to a user's terminal device by inputting a serial number, and that this information provision system can also be applied to the provision of video information.
  • One aspect of the present invention was made in consideration of the above problem, and realizes a device that, when playing back video contained in content associated with an identification code, allows the channel of the video to be switched.
  • the server device and display device according to each aspect of the present invention may be realized by a computer.
  • the control program for causing a computer to operate as each unit (software element) of the server device or display device to realize the server device or display device on a computer, and the computer-readable recording medium on which the control program is recorded also fall within the scope of the present invention.
  • a device can be realized that, when playing back video contained in content associated with an identification code, allows the channel of the video to be switched.
  • FIG. 1 is an example of a block diagram showing a functional configuration of a system 1 according to the present disclosure.
  • the system 1 is a system for transmitting video included in any content from a server device 10 to a display device (external device) 20 and playing the video.
  • a display device external device
  • one or more channels of audio included in the content are associated with the video, and the audio is played in parallel with the video in the display device 20.
  • the content will be described as including video of multiple channels.
  • a user can select and play video of any channel.
  • the system 1 includes a server device 10 and one or more display devices 20.
  • the server device 10 functions as a server that supplies content, and includes a control unit 11, a storage unit 12, and a communication unit 13.
  • the video and other data transmitted between the server device 10 and the display device 20 be encrypted before transmission and decrypted on the receiving device side.
  • the display device 20 is a device capable of outputting video and audio, and can be realized as, for example, a smartphone, a tablet, a personal computer, a television, or a game console.
  • the display device 20 includes a control unit 21, a storage unit 22, a communication unit 23, an input unit 24, and a display unit 25.
  • the control unit 21 is a control device that controls the entire display device 20, and includes a display control unit 211.
  • the display control unit 211 controls the screen display on the display unit 25.
  • the display control unit 211 causes the display unit 25 to display an image input to the display device 20 from the server device 10, for example.
  • system 1 may include multiple server devices 10, and the authentication of the above-mentioned identification code may be performed by an authentication device other than the server device 10. Furthermore, some of the components included in system 1 may be detachable from the server device 10 or the display device 20.
  • Table 31 in Fig. 2 is an example of a table showing the correspondence between contents and identification codes.
  • Table 31 shows that video content A includes video from channels A1 to A3, and video content B includes video from channels B1 to B3.
  • the value in the "Identification Code” column indicates which identification code is required for authentication in order to download the video of the corresponding channel to the display device 20. For example, in order to download the video of channel A3 to the display device 20, authentication using identification code "AAABBB222" or “AAABBB333” is required, and even if authentication using identification code "AAABBB111" is performed, the video of channel A3 cannot be downloaded.
  • the video of each channel included in a certain content may be the same, or may be the same content with only the video format or bit rate differing, or the content may be different from each other.
  • the content of the audio associated with each video, or the audio format or bit rate of the audio is usually different from each other.
  • at least any two of the videos of each channel included in a certain content may be different from each other, and the audio associated with the two videos may be different from each other.
  • the content is, for example, live footage of a singer
  • the footage on one channel may be footage of the entire singer group as the entire subject
  • the footage on another channel may be footage of one member of the singer group as part of the subject.
  • the selling price of an identification code for enabling playback of the video of a channel when viewed from a seating position close to the singer who is the subject of the video may be higher than the selling price of an identification code for enabling playback of only the video of the channel when viewed from a seating position farther away.
  • Table 32 is an example of a table showing the correspondence between an identification code and a display device 20 that has been registered by authentication using that identification code.
  • the denominator of the value in the "Number of registered units" column indicates the maximum number of display devices 20 that can be registered by authentication using the corresponding identification code. Furthermore, "registering" a display device 20 means storing the display device 20 that sent the identification code as a display device 20 that can download content associated with that identification code. Furthermore, as indicated by the fact that the denominator may be 2 or more, a single identification code may be input to each of multiple display devices 20, allowing content to be downloaded to each of the display devices 20.
  • the numerator of the value in the "Number of registered devices" column indicates how many display devices 20 are currently registered through authentication using the target identification code. For example, in the case of the identification code "AAABBB111,” the maximum number of three display devices 20 are already registered, so even if the identification code "AAABBB111" is entered into a new display device 20, that display device 20 will not be registered. It is also desirable to have a configuration in which it is possible to cancel the registration of that display device 20 by operating the input unit 24 of the display device 20, for example. This makes it possible to switch display devices 20 from which content can be downloaded, even if the number of devices that can be registered using a certain identification code has been reached.
  • the value in the "Registered display device” column is a value such as a MAC address that uniquely identifies an individual display device 20, and indicates a display device 20 that has been registered through authentication using the corresponding identification code.
  • the storage unit 12 of the server device 10 stores one or more authenticated identification codes in association with information identifying one or more display devices 20. Furthermore, when the acquisition unit 111 acquires information identifying the display device 20, an authentication process is performed using an identification code stored in the storage unit 12 that is associated with the information identifying the display device 20.
  • the authentication process may include, for example, authentication by the server device 10 alone, or authentication using another authentication device as described above.
  • the identification code may have an expiration date.
  • the storage unit 12 stores the expiration date of the identification code in association with the identification code. For example, the expiration date may be determined based on the period from when the identification code is first used for authentication, or the date and time when the identification code will no longer be valid may be determined in advance. For a single identification code, different expiration dates may be set for each piece of content, or for each channel. If the content is real-time live video or recorded live video, the identification code may be valid only during live streaming.
  • FIG. 3 is an example of a sequence diagram showing the flow of processing according to this example.
  • step S101 the control unit 21 of the display device 20 acquires an identification code input by the user via the input unit 24.
  • the input of the identification code and the playback of video and audio which will be described later, will be described as being performed using an application installed on the display device 20.
  • Screen 51 in FIG. 4 is a screen of the application, and shows an example of an input screen for an identification code.
  • input forms 52 and 53 are input forms for inputting an identification code.
  • a single identification code may be configured to include two or more character strings, or, for example, of the aforementioned "event code” and "serial code,” only the “serial code” may be treated as the identification code.
  • the acquisition unit 111 of the server device 10 acquires each piece of information received via the communication unit 13, and the control unit 11 performs authentication using the identification code. If the authentication is successful, the process of S104 is then executed.
  • the control unit 11 also associates the display device 20 that is the source of the identification code with the identification code and registers it in the storage unit 12 as a "registered display device" as exemplified in Table 32 of FIG. 2.
  • the display control unit 211 of the display device 20 performs processing to display the video of the content received by the communication unit 23 on the display unit 25. That is, when authentication using the identification code is performed, the display control unit 211 causes the display unit 25 to display the video of the first channel included in the content transmitted from the server device 10. Additionally, the control unit 21 plays back the audio included in the content. The control unit 21 also stores information identifying the content associated with the identification code for which authentication was successful in the storage unit 22.
  • control unit 21 transmits information indicating the specified channel to the server device 10.
  • the candidates for the channel that can be changed are the channels that correspond to the authenticated identification code. From another perspective, this means that the communication unit 13 is configured to transmit to the display device 20 the video of one of the one or more channels corresponding to the type of the authenticated identification code.
  • the display device may be configured in the above-mentioned aspect 8 such that the display control unit causes the display unit to display a list of contents associated with the authenticated identification code, and the communication unit transmits to the server device information identifying the display device and information identifying the content selected via the input unit from among the contents included in the list.
