SDR HDR 4K 4K based master switcher apparatus possible SDR and HDR processing

摘要

The present invention relates to a 4K-based master switcher device capable of standard dynamic range (SDR) and high dynamic range (HDR) signal processing, and more specifically, to a 4K-based master switcher device capable of SDR and HDR signal processing which receives UHD SDR image signals or UHD HDR image signals through a plurality of signal input terminals and performs a processing containing a converting processing, a bypass processing, and a downstream keyer (DSK) processing of input image signals according to selection of a user selection button for various signal processing for the input image signals. In addition, the 4K-based master switcher device capable of SDR and HDR signal processing analyzes image signals processed through the converting processing, the bypass processing, the DSK processing, etc., and monitors result information on the analysis. The device comprises a switcher controller (100) comprising: an image signal input unit (110); an image signal output unit (120); a control button unit (130); at least one processing unit (140); and a display unit (150).
