  • Patent number: 8385728
    Abstract: Provided are an apparatus and method for searching a start position of a broadcast program. According to an embodiment of the present invention, a received broadcast program is recorded in a recording medium while being output as video and audio. If a new broadcast program is started, position information regarding a start part of the new broadcast program is stored in a memory. Thus, a current broadcast program is reproduced from a start part by searching a start position of the current broadcast program recorded in the recording medium with reference to stored position information. A determination on whether the new broadcast program is started is done on the basis of Electronic Program Guide (EPG) information or a change in audio and video signals. Accordingly, it is possible to quickly search and reproduce a start part of a broadcast program which is currently recorded.

  • Patent number: 8368761
    Abstract: Disclosed herein is an image correction method for a camera system, which minimizes the amount of data that must be stored by a camera system and which can conveniently correct mounting errors of cameras. In the image correction method for a camera system, image data about a reference ground, which is captured by a camera and on which at least one ground mark is indicated, is acquired. Coordinates of a captured ground mark are obtained based on the image data. A preset Look-Up Table (LUT) is corrected using errors between the coordinates of the captured ground mark and coordinates of a preset reference mark. The ground mark and the reference mark may respectively have four or more corresponding correction points.

    Abstract: Integrated processing of audio/video signals can eliminate unnecessary signal processors and converters without losing the functionality of typical home entertainment system components. The integrated system includes a main player that captures and processes signals digitally, a dummy display, and a dummy speaker. The dummy display may only have a display panel and a panel driver. The dummy speaker may only have a driving unit and no crossover logic. The main player may have a PC architecture and process all signals digitally for outputting signals tailored for the display device and the individual driving units of the dummy speaker. The integrated system may also provide dynamic signal adjustments based on the surrounding environment. The main player may include a storage device and can process media content stored therein to produce supplemental information to provide an optimal audiovisual experience. This supplemental information can be shared among users over a network connection.
