摘要： A resource division, allocation, and transmitting/receiving method of downlink for reducing inter-cell interference in an orthogonal frequency division multiplexing system are provided. Entire downlink radio resources are divided into a traffic resource group for a traffic channel and a control resource group for a control channel, the traffic resource group is divided into a first traffic resource group for the intra-cell mobile terminals and a second traffic resource group for a cell-boundary mobile terminal, and a part of the first traffic resource group is imaginarily divided into a (1−1)-th preliminary traffic resource group, the (1−1)-th preliminary traffic resource group being a preliminary resource group for the cell-boundary mobile terminal. The control resource group is allocated to a control channel for the intra-cell mobile terminal; and a resource of the first traffic resource group or the second traffic resource group is allocated to a traffic channel for the mobile terminal according to inter-cell interference affected to the mobile terminal. Radio resources may be reused in each downlink cell of the OFDM system, the traffic may be rapidly transmitted to the cell boundary mobile terminal, a system capacity may be increased, the cell plane may be easily performed, and the system capacity may not be decreased although the mobile terminal number, locations, and traffic density is not uniform.

摘要： A method and apparatus to control reproduction of a media signal by using a tag includes receiving a request for generating tag information for controlling the reproduction of the media signal using a tag, generating the tag information according to the request for generating tag information, and storing the generated tag information in a tag. The tag information is generated independently from an original media signal and is used in controlling the media signal, and thus the reproduction of the media signal can be controlled without editing the media signal.

摘要： Simulation of electromagnetic characteristics of an electrical circuit uses netlist data defining component instances, including layout component instances, and their topological interconnection in an electrical circuit. A circuit simulation is performed using the netlist data, involving use of a model for each layout component instance. An attempt is made to retrieve an existing simulation model of the layout component instance from a database of such layout component simulation models. If no suitable simulation model can be found in the database, an attempt is made to interpolate a new simulation model from among existing simulation models in the database. If interpolation is determined not to be feasible, then an electromagnetic simulation of the layout component instance is performed to develop a new electromagnetic simulation model. This new model is used in the circuit simulation, and added to the database for future use.

摘要： A method of and apparatus for merging bit streams for seamless reproduction, and a recording medium for recording control information for bit stream merging. System clock reference (SCR) control information representing whether the SCR value of a bit stream is temporally discontinuous with respect to that of the preceding bit stream at the boundary between the two bit streams is recorded when the two bit streams are being merged. Thus, even where the SCR value at the boundary between merged bit streams rapidly changes when the merged bit stream is reproduced, seamless reproduction is accomplished. The SCR control information includes at least one among a control information identifier, a control information length indicator, a discontinuity indicator, and other information.

摘要： An automatic AV synchronization adjusting method and apparatus to automatically adjust a synchronization error between a video signal and an audio signal generated in an AV system. The method includes: generating video and audio test signals; measuring an audio delay amount from when the audio test signal is generated to when the audio is output form a speaker; measuring an video delay amount from when the video test signal is generated to when the video is displayed on a display device; determining a final audio delay amount by subtracting the audio delay amount from the video delay amount; and adjusting a delay of an audio signal generated by an AV source device based on the determined audio delay amount.

摘要： A recording medium includes a program containing video data and/or audio data and navigation information which defines a thumbnail, wherein the thumbnail relates to the program and is reproduceable as moving pictures. The recording medium may include a plurality of programs and the thumbnail may identify or represent one or more of the programs. By assigning a predetermined interval of a bit stream corresponding to a program as a thumbnail, the recording medium having the thumbnail thereon, that can be reproduced as moving pictures, can be obtained.
