Abstract: A method for an apparatus for transceiving IP based bidirectional advertisement are provided to enable a user to see, shop and buy advertisement and information the user wants. An IP-based bidirectional advertisement server(210) comprises a setting unit(211), an advertisement holder(212), a multicast transmitting unit(213), a unicast transmitting unit(214) and a detailed advertisement transmitting unit(215). The setting unit sets up a bidirectional advertisement receiving mode by a user. In this case, the setting is possible by referring to whether a network system to which the user belongs supports multicast. When the bidirectional advertisement receiving mode of a user A is set up as the multicast mode, a multicast group address according to the setting is assigned. And when the bidirectional advertisement receiving mode of the user A is set up as a unicast mode, the IP address of a server requesting the bidirectional advertisement is informed to the user.

Abstract: A bidirectional IPTV broadcast service method and a system thereof are provided to enable a guest to attend a broadcast remotely without inviting the guest to a studio, thereby supplying various type broadcast services. In a bidirectional IPTV broadcasting system, a broadcast controller(100) controls a bidirectional IPTV broadcast. A client(200) performs the existing IPTV STB function and simultaneously provides bidirectional IPTV broadcast services to a viewer. A platform server(400) transmits an actual broadcast stream to the viewer at a reserved time. A media server(300) controls the client participating in the bidirectional IPTV broadcast service. The media server performs a media server headend function which mixes media streams from the broadcast controller and the client.

Abstract: A personal DRM(Digital Rights Management)-applied personal multicasting service system and its providing method are provided to allow only an authenticated user to use a service to thus prevent improper contents from being broadcast or an unauthenticated user from illegally using a service. A personal broadcast transmitting unit(130) creates and stores contents, applies a personal DRM code to the created contents, and transmits the same to a personal broadcast receiving unit. The personal broadcast receiving unit(110) receives the transmitted contents, decodes the contents based on corresponding personal DRM certificates, and reproduces the same. After the personal broadcast transmitting unit allocates a channel for transmitting broadcast, a channel management server unit(140) manages the channel, and transmits information of a particular broadcast transmitting unit requested by the personal broadcast receiving unit. An authentication server unit(120) verifies the validity of the personal broadcast transmitting unit and the personal broadcast receiving unit, and issues/manages the personal DRM certificates.
Abstract translation: 提供个人DRM（数字版权管理）应用的个人多播服务系统及其提供方法，以仅允许经过身份验证的用户使用服务，从而防止不正当内容被广播或未经身份验证的用户非法使用服务。 个人广播发送单元（130）创建并存储内容，将个人DRM代码应用于所创建的内容，并将其发送到个人广播接收单元。 个人广播接收单元（110）接收所发送的内容，基于相应的个人DRM证书对内容进行解码，并再现。 在个人广播发送单元分配用于发送广播的信道之后，信道管理服务器单元（140）管理该信道，并且发送由个人广播接收单元请求的特定广播发送单元的信息。 验证服务器单元（120）验证个人广播发送单元和个人广播接收单元的有效性，并发布/管理个人DRM证书。
