Broadcast level monitor and monitoring picture generating method

Abstract

The invention provides a broadcast level monitor. The broadcast level monitor comprises a signal receiving module, an FPGA video picture processing module, a display screen driving module and a display screen which are arranged in sequence, and the FPGA video picture processing module is connected with a memory module; the FPGA video picture processing module comprises a signal conversion module, a video stitching module, a video region dividing module, an waveform diagram generating module, a vector diagram generating module and an alpha aliasing module. And a monitoring picture generating method is further provided. According to the broadcast level monitor, the waveform analysis conducted on four SDI signals at the same time and the display conducted on the four SDI signals at the same time on one monitor are achieved, so that the consistency of the color of four pictures is guaranteed; by the adoption of the FPGA field-programmable gate array, parallel processing conducted on the four SDI signals is achieved, the speed is fast, the peripheral devices are few, the structure is simple, and the cost is low.

Description

technical field [0001] The invention relates to a broadcast-level monitor, in particular to a four-screen broadcast-level monitor capable of independent waveform analysis for each channel and a monitoring image generation method. Background technique [0002] At present, the four-screen monitor with waveform analysis at home and abroad is usually a video screen, and the other three screens are filled with waveform diagrams, and only one video source is used for waveform analysis. In the application that needs to analyze multiple channels of video data at the same time, four monitors are needed, and because the color performance of the LCD panel of each monitor will be different, it is difficult to adjust them to be consistent. When used in this way, it not only takes up a large space, is inconvenient to carry, but also increases the cost. More importantly, color consistency is difficult to guarantee. Contents of the invention [0003] In view of the deficiencies in the p...
