A method and video device are disclosed for accessing information. In an embodiment of the present invention, part of data included in a title, being played, read from a storage medium or extracted from a broadcast signal is extracted and sent to a server over a network, and information corresponding to the part of the data (i.e., information related to the data and complete data of the data) is received from the server and played. Rather than the part of the data, information related to a position of the data, (e.g. a time point at which the playing of the data starts within the title or a radial position or a physical address at which the data is located in the storage medium) may be sent. The data may be data that forms audio, a frame-shaped video clip or a frame-shaped picture included in the title.

The present invention relates to an apparatus and method for providing and obtaining product information through a broadcast signal. In this present invention, information identifying a product item, which is in a scene to be presented from a broadcast signal, is provided together with a broadcast signal, then a signal receiving terminal stores the product information for a new product item and displays the stored information to a viewer to select one product item while or after watching an interesting broadcast program, and transmits data identifying a selected product item to a predetermined web site and receives web site address for the selected item from that site. As a result, detailed information for the selected item is acquired from a server addressed by the received web site address.

A key signal input circuit for a microcomputer including a microprocessor and a single input port. The microcomputer outputs, in sequence at a constant interval, a plurality of grid signals, receives different key signal inputs successively through the single input port synchronously with the grid signals, and discriminates the inputted key signals to recognize which keys have been selected. The key signal input circuit includes a power supply circuit, responsive to the grid signals from the microcomputer, having a plurality of power supply lines for supplying, in sequence at a constant interval, a desired power through the power supply lines. A key matrix circuit having a plurality of sets of keys, responsive to the desired power through the power supply lines from the power supply circuit and to on/off states of the keys, coupled, by sets, respectively to the power supply lines. The key matrix circuit applies the key signals successively to the microcomputer.

Key signal input circuit for microcomputer

An automatic clock-setting apparatus and method, which can recognize clock-displaying characters as numerals included in a television broadcasting signal when the clock-displaying characters are displayed on a screen, and which can automatically set a current time of a built-in timer of a television or a video cassette recorder by the recognized numerals. According to the invention, it is possible to set a clock exactly and to make the clock-setting operation by the user convenient.

Clock-setting apparatus and method utilizing broadcasting character

An apparatus and a method for automatically controlling pulse generation. The apparatus comprises a drum having video heads, a pulse generating head and a frequency generation head, first and second wave-shapers for wave-shaping a pulse generation signal from the pulse generating head and a frequency generation signal from the frequency generating head, respectively. There is also provided a mono-multi signal generator outputting a mono-multi signal having a rising curve time, a servo device for outputting a head switching signal in response to the mono-multi signal and outputting a drum control signal in response to the pulse and frequency generation signals and the head switching signal to control the speed and phase of the drum. There is further provided a luminance/chrominance processing circuit for selecting a channel for inputting one of video signals played back by the video heads in response to the head switching signal, for processing luminance and chrominance of the video signal from the selected channel and for outputting the processed video signal, and an automatic mono-multi signal control circuit for separating a vertical synchronous signal from the video signal, varying the rising curve time of the mono-multi signal in accordance with a time interval between the separated vertical synchronous signal and the head switching signal for thereby correcting an error of the head switching signal based on the rising curve time of the mono-multi signal.
