Abstract: When creating other tool path from two tool paths for cutting a work accurately and efficiently, the data on the first tool path is composed of a position vector and a direction vector of a tool for use when the work is cut while moving the tool. The data on the second tool path is composed of a position vector and a direction vector of the tool for use when the work, which has been cut according to the first tool path, is further cut. A computer uses the first tool path data and second tool path data to calculate a position vector and a direction vector of a medium tool path that is between the first tool path and second tool path.

Abstract: A digital broadcasting system includes an authoring apparatus and a transmission apparatus. The authoring apparatus generates event information, which defines an event message that should be transmitted immediately after an operator's instruction to transmit the event message is received, and adds the event information to a content. The authoring apparatus then extracts the event information from the content by referring to tag information and transfers the extracted event information to the transmission apparatus. The transmission apparatus stores the event message defined by the event information transferred from the authoring apparatus. According to an operator's instruction to transmit the event message, the transmission apparatus issues the event message, and multiplexes and transmits the issued event message and the content.

Abstract: The present invention relate to a digital broadcast system, and it is an object of the invention to record contents quickly in a broadcast system which implements interactivity by transmitting a set of data repeatedly, wherein a digital broadcast receiver separates a table corresponding to video images from streams in an arbitrary order and repeats the processing of memorizing the video image data to be identified in the order of obtaining the same by means of the table corresponding to the video images until all of the set of video images have been memorized. This allows for performing, in a short time, storage process of video image data broadcast for the purpose of efficient reproduction by a receiver having no storage function. Additionally, the data is available to viewers at any time after the completion of storage thereof.

Abstract: When a program transmission apparatus divides a program into a plurality of partial programs before transmission, a program reception execution apparatus executes a partial program when the partial program has already been received, and, when the execution needs to proceed to from a present partial program to a next partial program, executes the other partial program when the next partial program has been received.

Abstract: A data broadcast apparatus repeatedly broadcasts data using a carousel method, to a reception apparatus which stores the data into a memory and reproduces the data stored in the memory. A storing unit stores first data and second data. A detecting unit detects an event which prohibits the reception apparatus from reproducing the first data. A broadcasting unit repeatedly broadcasts the first and second data stored in the storing unit, and stops broadcasting the first data when the detecting unit detects the event. An instructing unit has the broadcasting unit broadcast a switch instruction, which instructs the reception apparatus to stop reproducing the first data and start reproducing the second data when the broadcast of the first data is stopped.
