Realization method of caption machine with remote control interface

Abstract

The invention discloses a realization method of a caption machine with a remote control interface, comprising the following steps: the caption machine receives trigger information sent by peripheral equipment through a general purpose interface (GPI); the GPI sends the trigger information to a controlled interface card to provide information feedback for the lower layer of caption machine software and realize the controlled operation of computer programs; the controlled interface card transmits logic information to the caption machine and controls the caption machine to simultaneously broadcast animation by software. The invention adopts the caption machine remote control interface and related software to realize the automatic broadcast function of multi-thread captions, while an operator scans the animation on a switching desk, the switching desk sends out an instruction to broadcast the animation synchronously on the caption machine, thus not only simplifying the operation but also ensuring the perfect safety in live broadcast; the animation synchronous switching and broadcasting process has manoeuvrability in live broadcast, and the operators are free from heavy manual work, thus proving an effective means for safely and conveniently broadcasting the captions.

Description

technical field [0001] The invention relates to the field of radio and television, in particular to a method for realizing a subtitle machine with a remote control interface. Background technique [0002] At present, in the live broadcast of large-scale international sports events, when replaying highlights in slow motion, a LOGO animation designated by the organizer is generally used as the way of screen transition. Wherein, one kind of realization method is: use the stunt switching device that can store and play animation, store the LOGO animation that has done in advance in the RAM (Random Access Memory, random access memory) of this stunt switching device, directly in live broadcast The special effect switching device is called, and the operation is just like doing normal scanning, which can be completed by one person, which is very convenient, simple and extremely reliable. Another implementation method is: when the special effect switching equipment used cannot store ...

AI Technical Summary

Problems solved by technology

[0007] In the existing technology, the combination of subtitle machine and switcher is used for animation sweeping, which is relatively complicated in operation and requires the participation and cooperation of at least two people. In practice, two operators are required to cooperate well from beginning to end in a live broadcast of a game ,difficult to realize
