Abstract: The present invention relates to a signal transmission and reception device and a signal transmission and reception method. The signal transmission method, according to one embodiment of the present invention, comprises the steps of: encoding UHD video data; encoding signaling information for signaling a UHD broadcasting service based on the encoded UHD video data; and multiplexing the encoded video data and signaling information, and transmitting the multiplexed data, wherein the signaling information contains identification information on a clear QAM UHD service.

Abstract: According to the invention, a video distribution system is disclosed. The video distribution system distributes a video program in a first aspect ratio and includes information to convert the first aspect ratio to a second aspect ratio. Included in the video distribution system are a distribution point and a video converter that is located remotely from the distribution point. The video converter receives the information and the video program from the distribution point. The video converter uses the information to guide conversion between the first aspect ratio and the second aspect ratio.

Abstract: A method of recording a broadcasted programs based on ratings is disclosed. The method includes setting a watching restriction rating of the broadcasted program according to user commands, detecting rating restriction information in a broadcasted signal, associated with the broadcasted program, received when the broadcasted program is recorded, and comparing the detected rating restriction information with the set watching restriction rating, and automatically setting a password to be associated with the recording of the broadcasted program when the detected rate restriction information is higher than the set watching restriction rating.

Abstract: An adaptive binaural beamforming system is provided which can be used, for example, in a hearing aid. The system uses more than two input signals, and preferably four input signals. The signals can be provided, for example, by two microphone pairs, one pair of microphones located in a user's left ear and the second pair of microphones located in the user's right ear. The system is preferably arranged such that each pair of microphones utilizes an end-fire configuration with the two pairs of microphones being combined in a broadside configuration. Signal processing is divided into two stages. In the first stage, the outputs from the two microphone pairs are processed utilizing an end-fire array processing scheme, this stage providing the benefits of spatial processing. In the second stage, the outputs from the two end-fire arrays are processed utilizing a broadside configuration, this stage providing further spatial processing benefits along with the benefits of binaural processing.
