Description

  The present invention relates to a broadcast communication system and method for supporting communication between users regarding digital broadcasting, and more particularly to a broadcast communication system and method for supporting communication between users for a program distributed in digital broadcast.

  In recent years, television broadcasting is shifting from analog broadcasting to digital broadcasting. In digital broadcasting, in addition to conventional program broadcasting, a television receiver or the like can receive various information such as character information. Various information such as character information can be received by a television receiver or the like through a broadcast wave together with a program broadcast, or can be received through a communication network. And a system using various information such as the character information has been proposed. For example, a television receiver that has received access information to a Web server together with a program broadcast transmits the received access information to a nearby mobile phone, thereby acquiring content linked to the program from the received access information. Then, a content providing system for displaying has been proposed (see, for example, Patent Document 1).

  By the way, in recent years, the use of the Internet for broadcasting programs has increased. For example, on social media such as TWITTER (trademark), bulletin boards, and blogs, when a program is broadcast, various information about the program is transmitted as word of mouth, and active communication between users is performed. Such word-of-mouth for a program between users has an effect of activating user purchasing behavior.

  However, in the system described in Patent Literature 1, since word-of-mouth transmitted from a user to a program cannot be displayed on a mobile phone at the time of program broadcasting, communication between users can be realized on the mobile phone. In addition, the word-of-mouth effect cannot be realized.
