  • Patent number: 8880205
    Abstract: Integrated processing of multimedia signals can eliminate unnecessary signal processors and converters without losing the functionality of typical home entertainment system components. The integrated multimedia system includes a main player that captures and processes signals digitally. The main player may adjust the audio signal to provide audio output of equal loudness across all frequencies by accounting for sensitivity of the human ear for sounds of varying frequencies. The main player can also account for perceived differences in loudness based on the angle of a listener to a speaker by detecting the position of a user and making an adjustment accordingly. The invention further provides a speaker that has embedded performance characteristics or an identifier that allows the system to provide an optimal speaker driving current for a particular system or determine how that speaker would be best implemented in the integrated system.

  • 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.
