A template file defines a video material data, a first still picture material data, a second still picture material data and text data, and a display area for each of the material data. A presentation file defines the template file and a correlation between each of the display areas and each material data. Based on the template file and the presentation file, an information display device combines and displays as a program the video material data, the first still picture material data, the second still picture material data, and the text data in their respective display areas.

Program display method, program display apparatus, and program delivery and display system

Provided is image processing technology capable of displaying lines on a field clearly on a screen regardless of the distance to the viewpoint or the visual direction. This image processing method has a step for disposing a linear model formed from multiple polygons in a coordinate system of a three dimensional space based on an image processing program stored in a memory, a step for setting a viewpoint in the coordinate system, a step for performing perspective transformation to the model viewed from the viewpoint, and a step for drawing a linear texture having a prescribed dot width in a frame buffer at a coordinate position after the perspective transformation of the model. The linear texture is drawn on the model in a width of minimum dots regardless of the width occupying the coordinates after the perspective transformation of the model.

Image processing

An information delivery and display system includes one or more information display devices that play display information, and a monitoring/control server that sends information to the information display device when the information display device carries out polling at predetermined time intervals. The monitoring/control server includes a control instruction unit that creates control instruction information to change a polling interval of the information display device and that sends the created control instruction information to the information display device when the information display device carries out polling.

Information delivery and display system and information delivery method

The file creating processing unit creates at least one material data and at least one control information file to display the material data in a presentation package storage folder corresponding to a presentation pack. When a package creating processing unit receives a delivery designation, the package creating processing unit creates at least one package from all files in the presentation package storage folder to satisfy a predetermined condition and delivers presentation packs in units of packages to an information display device through a data distribution server.

Information delivery display system and information delivery display method

A method of and an apparatus for processing communication data transmitted from a data center such as a sing-along data center to a terminal communication apparatus such as a communication type sing-along apparatus via a communication line. The method and apparatus are such that a data file may be stored in a first memory provided in the terminal communication apparatus when said data file has been transmitted from the data center while the terminal communication apparatus itself is not in operation, a version of the data file stored in the first memory is compared with a version of an existing data file formerly recorded in a second memory provided in the terminal communication apparatus when said terminal communication apparatus is in operation and said second memory is in ON state, the data file formerly recorded in the second memory is replaced by the data file recorded in the first memory if it is determined that the version of the data file recorded in the second memory is older than the version of the data file recorded in the first memory.

Method of and apparatus for processing data transmitted through a communication line

A data management device in a karaoke system which receives a first data file by a receiving unit and is stored in a rewritable memory such as a hard disk. A second data file, recorded on a recording medium such as a CD-ROM, is read out by a reading unit. A file number comparing unit then compares the file numbers of the first and second data file and a file managing unit erases the first data file if the file numbers coincide with each other. In addition, a version comparing unit compares versions of both the first and second data file. If the first data file version is older than the second data file version, then the file managing unit erases the first data file version, so as to ensure that the new version is always used. Furthermore, a detecting unit detects whether data files corresponding to targeted items are recorded in both, the rewritable memory and the recording medium. In the event that data files are recorded in both, the file managing unit erases the data file in the rewritable memory.

Data management device in a karaoke communications system

A music reproduction control apparatus includes: a first storing unit for storing main-digital data; a second storing unit for storing sub-digital data; a first reproducing unit for reproducing main-sound based on the stored main-digital data; a second reproducing unit for reproducing sub-sound based on the stored sub-digital data; a receiving unit for receiving an input signal; a first changing unit for changing a reproducing speed of the first reproducing unit based on the received input signal; a second changing unit for changing a reproducing speed of the second reproducing unit based on the received input signal; a correcting unit for correcting a key of the sub-sound in accordance with a change in the reproducing speed of the second reproducing unit; and a synchronizing unit for synchronizing a timing of changing the reproducing speed of the first reproducing unit with a timing of changing the reproducing speed of the second reproducing unit.
