摘要:
A picture display system in which a picture in the high definition television system is converted into a picture in the conventional television system is provided. The picture display system samples a desired part of picture in the high definition television system, converting a high definition video signal which forms the sampled desired part of the picture into a conventional video signal in the conventional television system, and displays the conventional video signal. The picture in the high definition television system may be divided into a plurality of desired parts, each of which is converted into a conventional television signal. Each of the plurality of desired parts is subsequently displayed on conventional televisions which are arranged to form a single large picture as a whole.

A remote line monitoring device and method for a CATV system in which a center facility is connected to plural terminal units through cables of the system to transmit television signals to subscribers' homes. A plurality of monitoring terminal units are provided along various points of the interconnecting cables. Each of the monitoring terminal units is identified by an unique address. To determine conditions throughout the system, a central monitoring system transmits polling signals on the cables. If an address contained within the polling signals matches with a prestored identifying address, a monitoring terminal unit responds by transmitting data produced by monitoring converter units back to the center facility. The center facility can then display the data or produce indications identifying problems along the cables.

A line monitoring device for use in a two-way data communication system such as a CATV system in which up-signals are transmitted by terminal units in response to retrieving signals applied thereto from a central facility to monitor the levels produced by the various terminal units. An address detection signal compares the address number included in a polling down-signal from the central facility with an address prestored in the monitoring device. A response signal detection section detects the up-signals from the terminal units. A display section operates in response to the address detection section to display the level of an up-signal from a terminal unit as produced on the output of the response signal detection section when the address received from the central facility coincides with the pre-stored address.

An apparatus for reproducing a television broadcast program digest which stores a broadcast signal indicative of contents of at least one television broadcast program and guide data of the at least one television broadcast program. The apparatus pre-stores a period of time and a weight point as data for at least one attribute concerning program contents every different television broadcast program. The apparatus reads the broadcast signal and guide data of the at least one television broadcast program when a digest reproduction is performed. In accordance with the guide data, the apparatus reads a period of time and a weight point for each attribute corresponding to a television broadcast program consistent in terms of content with or similar to the at least one television broadcast program. The apparatus reproduces a partial signal having a length of time based on the weight point and the period of time.

An information serving system includes a broadcasting station module (TV), user module (RV), and advertising agency module (AD). The broadcasting station module (TV) broadcasts pieces of broadcast information including at least video information. The user module (RV) receives the broadcast information, selects an image component composing an image from the received broadcast information, and produces specification information indicative of the selected image component. The user module (RV) transmits the produced specification information, while receiving component information to represent the received component information. The advertising company module (AD) acquires the specification information, and transmits to the user module (RV) the component information indicating an image component specified by the acquired specification information. This allows a viewer viewing a broadcasted program to acquire detailed information about a desired image component in an easier and quicker manner, thus enhancing usability of a broadcasting business.

A navigation apparatus, which is to be mounted on a movable body, comprises a navigation information acquisition unit, a requirement judgment unit and a control unit. The navigation information acquisition unit acquires navigation information relating to movement of the movable body. The requirement judgment unit judges as whether or not dialog start requirements are satisfied on the basis of the navigation information. The control unit gives a speech to a user to start providing interactive information, in case where the dialog start requirements are satisfied.

A scanning line converting system comprises down-converters arranged in parallel for converting an input high definition television signal to a current television signal, and double-frequency converting sections for respectively doubling the frequency of the down-converted current television signals, for synthesizing them, and for delivering the synthesized signal as a non-interlaced video signal. The non-interlaced video signal can be obtained by properly controlling a vertical filter which is a part of the down-converter with no additional interlace/non-interlace converting unit.

An interactive information providing apparatus is provided with: an output component that provides an information requesting output for requesting a user for information; an input component that receives from the user input information to the information requesting output; and an interaction controller component that controls the output component and the input component according to a scenario, to carry on a dialogue with the user. In the apparatus, the interaction controller component changes a level at which the output component requests a user for information, according to an importance parameter associated with the scenario.
摘要:
When a composite color TV signal of standard NTSC system with a 4-to-3 aspect ratio and 525 scanning lines is received by a TV receiver with a large aspect ratio of 16 to 9, the NTSC signal is separated into a color video signal for picture and a character data signal. The color video signal for picture is written into a first buffer at a timing of a first clock whose frequency is four times that of an input color subcarrier. The character data signal is written into a second buffer at a timing of a second block with a frequency 16/5 times that of the color subcarrier. The picture video signal and the character data signal are alternately picked up by a selector that swiches between the two buffers at a specified horizontal position on the screen at a timing of a third clock whose frequency is 4/3 times that of the first clock. The output of the selector is fed to the TV receiver to produce a picture on one side of the screen and character data on the other side, utilizing the whole area of the screen. This prevents uneven degradation of the CRT, as would be caused by a partial use of the screen.
