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:
An apparatus and a method for converting a protocol are disclosed. The apparatus of the present invention comprises a message filter part for comparing a first protocol based input message with a message mask stored in a mask storage part, obtaining a unique type identifier, making the message mask filter the input message and obtaining a message parameter; and a message generating part for extracting a message template corresponding to the unique type identifier from a template storage part, integrating the message parameter with the message template, and generating a second protocol based output message. The present invention extracts effective data from the input message by using the message mask generated by previously analyzing the protocol, thereby easily converting the input message according to a target protocol and being widely applied to a legacy message protocol obtained from an existing device, and rapidly being applied to a target system.

Abstract:
PURPOSE: A customized service providing system and a method thereof are provided to compare content to identity in a mobile device of a user, thereby reducing costs for building a media ID storage. CONSTITUTION: Each media ID buffer(401~40n) stores a media ID and time stamp information which are generated in a media ID generator. The time stamp information identifies time for generating the media ID. A communication unit(501) reads a media ID of at least one channel stored in the media ID buffer. The communication unit generates an ID list. The communication unit outputs the media ID list to a mobile device.
