Abstract

PROBLEM TO BE SOLVED: To automate execution of telop by presetting time data used to set telop display start and erasure times to a telop text and superimposing characters or the like on a video image at a time designated by the time data of the telop text. SOLUTION: Data of a telop text generated by a prescribed method are once stored in a telop data storage section MEO and read from the telop data storage section MEO in matching with a video image such as a broadcast program according to the setting of telop data K time setting part and a clock of a time control section TME, converted into a video signal and synthesized with the video image. Since keeping an accurate time of the clock of the time control section TME of a video signal synthesis device PCA is a requirement, the time is corrected by a synchronizing signal such as a time cast signal from a television tuner applied to an input terminal PIN of a time synchronizing signal.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image synthesizing apparatus having a clock function, and more particularly, to an apparatus for synthesizing a telop for superimposing a character or the like on a video screen, in which a telop time is set in advance. It is something that can be done.

[0002]

2. Description of the Related Art In recent years, telops for superimposing characters and the like on video screens of television broadcasts and the like have been widely used, and various apparatuses have been developed in which automation is performed by computer control. It has been introduced and used in many broadcasting stations and video studios.
For example, Japanese Patent Application Laid-Open No. 9-135386 discloses a telop data control unit that controls the display time of a telop sentence in accordance with the number of characters in the character string data of the telop sentence to be displayed. Also disclosed is a television broadcasting telop device that can obtain an appropriate display time without manual intervention for each character string of a telop sentence divided into line by line in a composed telop sentence. In this broadcast telop device, a time control table for controlling the display time of the telop text is provided in the telop data control means in advance, and the display time control is performed based on the number of characters obtained by counting the character string data of the telop text. By referring to the table, the display time of the telop text is set based on the obtained time control data. However, even in these apparatuses, the start and end of a telop for superimposing characters and the like on a video screen are manually performed.

[0003]

For this reason, it is difficult to make a telop such as a notice that keeps characters and the like flowing on a video screen on a daily basis. In TV broadcasts, there was a problem that telops such as announcements and communication from the local government were manually performed between a certain broadcast and another broadcast, so that the operation was nervous and time-consuming. was there. An object of the present invention is to automate the execution of a telop in order to solve such a problem of the conventional video synthesizing apparatus.

[0004]

A video synthesizing apparatus having a clock function according to the present invention provides a video synthesizing apparatus which performs a telop for superimposing characters and the like on a video screen, and has a clock function. A time data setting unit for setting the start time and the end time of the telop is provided so that the time for performing the telop can be preset in the telop sentence.
By reading the data set in the time data setting section of the telop sentence and superimposing characters etc. on the video screen at the specified time, the telop can be automatically performed at the specified time in advance. It is one that can be set.
