用于控制演播室直播延时系统的控制电路技术方案

本发明专利技术公开了一种用于控制演播室直播延时系统的控制电路，它包括主控单元、扩展单元、按键指示灯单元，该主控单元分别与扩展单元、按键指示灯单元相连，该扩展单元与多个延时系统相连。控制电路还包括固件升级单元。本发明专利技术控制电路可同时启动多个延时系统工作，通过延时系统控制相应直播系统运行，从而保证意外发生时的画面及时切换，避免不正常画面或声音播出，减轻导播人员直播时的紧张程度，减少播出事故。本发明专利技术控制电路适用于具有一主延时系统与三备延时系统、一主延时系统与一备延时系统或单延时系统的直播系统环境中。

Control circuit for controlling studio live broadcast delay system

The invention discloses a control circuit for controlling studio delay system, which comprises a main control unit, expansion unit, key indicator unit, the main control unit is respectively connected with the expansion unit, key indicator unit, the expansion unit is connected with a plurality of delay system. The control circuit also includes a firmware update unit. The control circuit can also start multiple time delay system, time delay control system through the corresponding broadcast system, so as to ensure the picture switching in time when the accident occurred, to avoid abnormal picture or sound broadcast, reduce the degree of tension when the director staff live broadcast, reduce accidents. The control circuit of the invention is suitable for a live broadcast system with a main delay system and a three standby delay system, a main delay system, a standby delay system or a single delay time system.
