TECHNICAL AND METHOD FOR ISSUING RIGHTS OF SEEING AND HEARING ABOUT BROADCASTING BY MEANS OF WIRELESS NETWORK, AND SERVER APPLIED TO THE SAME}

The present invention relates to granting broadcast viewing authority. More particularly, the present invention provides not only a common broadcast that all subscribers can watch through a broadcasting network, but also an additional service provided to a specific subscriber group in connection with common broadcast. The present invention relates to a mobile communication network based broadcasting viewing authorization system and method for granting a broadcasting viewing authority to a specific broadcasting viewing subscriber who did not have the broadcasting viewing authority, and a server applied thereto.

The features of digital broadcasting are summarized as multichannel, high quality and multifunctional. In particular, with the development of multiplexing technology, video, audio, and data can be bundled and transmitted simultaneously regardless of content and size, and a return channel through a modem is formed to enable interactive service. Accordingly, digital broadcasting can overcome the limitations of existing analog broadcasting and provide high value-added multimedia services to viewers. However, in the integrated broadcasting of digital data, if mutual security is not established between the transmitting side and the receiving side, the commercial structure of the broadcasting collapses. In addition, broadcasters seek to provide high-quality broadcasting services to subscribers and to provide paid broadcasting services to collect subscriber fees from their existing advertising revenues by activating multi-channel and professional channels. It is hoped that only authorized subscribers who are protected and legitimately receive can receive. The CAS (Conditional Access System) was developed to solve this problem.

CAS is a system that introduces the concept of subscribers to a broadcast so that only subscribers with legitimate viewing rights can receive a particular program. A set of digital broadcast receivers allows the receiver to determine whether a particular broadcast program can be received. It means the process. The CAS transmits an encrypted program signal at the transmitter and entitlements given to individual or specific groups of recipients.On the receiving side, only authorized subscribers use a smart card mounted on the receiver to decrypt. To receive a program.

In general, CAS scrambles A / V streams into CW (Control Word), multiplexes and transmits ECM and EMM encrypted CW, and decrypts the ECM and EMM using a smart card at the receiving side to obtain CW and scramble Descrambled A / V streams.

Furthermore, DRM is applied to the broadcast content to protect the copyright of the broadcast content provided by the broadcast service. Accordingly, the trend of the broadcast service is that the CAS and the DRM converge to meet the requirements between the content provider and the service user. We aim to upgrade the system.

In accordance with this trend, only the corresponding broadcast contents are stored according to a scheduled schedule for each broadcasting service user, so that the user can watch the broadcast whenever there is time, or save the broadcast contents of another channel while watching the broadcasted broadcast and later watch the broadcast. Research to meet the needs of service users, etc., is being actively conducted.

In addition, due to the characteristics of broadcasting, there is a need to provide differentiated contents for specific users only, rather than to all subscribers subscribed to broadcasting services, and to create related additional services.

Accordingly, there is a need for a method for not only targeting all subscribers but also providing differentiated broadcasting services to specific subscribers.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is not only to provide a common broadcast that all subscribers can watch through a broadcasting network, but also to provide a specific subscriber group with respect to common broadcast.
