摘要:
An audio and video recording and reproduction apparatus and method is described, which uses a movable storage memory such as a memory card, so that audio and video signals are easily accessed without separate editing devices. The apparatus uses a separable memory so that a deck is unnecessary, allowing small, lightweight constructions, and a compression algorithm results in longer playing time, while read/write operations robust to noise are achieved. Also, data desired by the user is easily accessible, and applications as a substitute for magnetic or disk media are also possible.

The present invention relates to a device for generating a signal and method for controlling operation of the same. The present invention provides a device for generating a signal, which includes an electrode (110), if connected to an external power source (200), supplied with a voltage from the external power source (200), a signal generating unit (130) having a plurality of terminals, the signal generating unit (130) deciding whether to operate the device according to a size of a voltage applied to a first terminal among a plurality of the terminals, the signal generating unit (130) outputting a prescribed signal according to the decision, and a control circuit (120), if the electrode (110) is connected to a plurality of the terminals, controlling a voltage applied to a plurality of the terminals. Accordingly, the present invention is able to control whether to operate a signal generating device (100) using an external power source (200).
摘要:
This invention relates to a karaoke CD format and a device for controlling audio signals utilizing the karaoke CD format which provides a user with selective reproduction of the voice of a player. The karaoke CD format includes a CD format divided into video sectors and audio sectors. The audio sectors are further divided into a part for recording accompaniment sound and playing sound at the same time and a part for recording accompaniment sound only. There is provided record coding information for distinguishing the parts. An apparatus, method and storage medium for processing digital data are discussed. According to an embodiment, the apparatus includes an audio/video data processor to receive data units of digital audio data and data units of digital video data, the data units of digital audio data being multiplexed with data units of digital video data, the data units of digital audio data corresponding to at least one of: 1) a first type of digital audio data, and 2) a second type of digital audio data which includes at least one content different from the first type of digital audio data; each type of digital audio data being specified by attribute information, which has: a) first information for indicating a coding mode of the digital audio data, and b) second information, different than the first information, for identifying one of the first type of digital audio data and the second type of digital audio data, and the digital video data associated with two types of digital audio data.

摘要:
A capsule-type endoscope is disclosed. Information related to position and movement of the capsule-type endoscope inserted into a body are checked and a frame rate is controlled according to a digestive organ in which the capsule-type endoscope is located based upon the information, so as to capture every digestive organ inside the body by using one capsule-type endoscope. Also, the frame rate can be controlled according to a moving velocity in each digestive organ, thus to reduce unnecessary power consumption, resulting in a decrease of an operation time of the capsule-type endoscope having a limited battery capacity. In addition, an amount of captured images can be reduced by effectively obtaining images according to the moving velocity in each digestive organ and a time taken by a doctor for a medical examination can be shortened.
