Abstract: A service identifying and processing method using a wireless terminal message according to an exemplary embodiment of the present invention includes (a) receiving a wireless terminal message by a first entity which is a mobile device; and (b) expressing, by a first agent which is an information processing application program installed on the first entity, entity information of second entity based on the wireless terminal message and service confirmation information related to service provided by the second entity, through an application screen by the first agent.

Abstract: A method of performing trick play on a scrambled data stream, the method comprising: extracting position information corresponding to scrambling information from an input scrambled transport stream; demultiplexing a transport stream of a predetermined position according to the stored position information of the scrambling information and extracting the scrambling information and a scrambled data stream pertaining to the scrambling information; descrambling the extracted scrambled data stream by using the extracted scrambling information; and decoding a reference picture based on the position information.

Abstract: Provided are a method and apparatus for reproducing a digital broadcast having different compression formats and a method of recording the digital broadcast so that the digital broadcast may be consistently stored and reproduced regardless of a compression format of the digital broadcast. The method of reproducing a digital broadcast includes receiving a transport stream of the digital broadcast which is provided in a compression format; extracting an original stream of a desired program by demultiplexing the transport stream and extracting metadata from the original stream for reproducing or performing trick-play functions on the original stream; separately storing the original stream and the metadata; and decoding the original stream in accordance with the compression format and displaying the original stream. The method and apparatus allows a user to consistently perform functions on the digital broadcast regardless of a compression format of the digital broadcast.

Abstract: A cathode ray tube (CRT) having a particular funnel configuration allows electron beams to be deflected to the phosphor surface of the panel without obstruction. The configuration of the yoke attachment portion of the funnel is based upon a curvature of an inner surface of the funnel and based upon a thickness of the funnel. The inner surface of the yoke attachment portion is at a recession from the curvature of the inner surface of the funnel. In one embodiment, if the depth of the recession is S and the thickness of the funnel is T, the recession depth of the inner surface of the yoke attachment portion is 0.1×Tmm≦S≦0.5×Tmm.
