Split type broadcast and TV SDI monitor

Abstract

The invention provides a split type broadcast and TV SDI monitor which comprises an FPGA processing circuit. The FPGA processing circuit is connected with a central processing unit, a DDR3 memory device, a flash memory device and an RAM memory. The FPGA processing circuit is connected with an SDI equalizer. The FPGA processing circuit is connected with HDMI input equipment through an HDMI variable-frequency unit circuit. The FPGA processing circuit is connected with an HDMI one-to-two unit circuit through an HDMI transmission unit circuit. The FPGA processing circuit is connected with a monitor screen control circuit. According to the split type broadcast and TV SDI monitor, a chip designing principle and an autonomous innovation concept are utilized, thereby realizing high system integration degree, higher autonomous technological content, higher exploitability and higher upgrading degree. Furthermore more convenient connection of the whole product is realized. Higher adaptability is obtained. On the condition that a total cost is reduced, high performance is kept. Furthermore an extend port lays a foundation for product updating in future.

Description

technical field [0001] The invention relates to the technical field of radio and television, in particular to a split-type radio and television SDI monitor. Background technique [0002] With the development of science and technology, especially the application of high-definition technology in radio and television equipment, people have higher and higher requirements for the clarity, stability, and bandwidth of TV programs. In this context, there are more and more high-definition programs. It is accepted by people, and people want to see clearer and smoother TV programs. At present, most domestic TV programs are still in standard definition. The conversion from standard definition devices to high-definition devices is not only expensive but also not stable according to the current equipment prices on the market. At the same time, most of the high-definition devices on the market are It is independent, and there is a need to connect between devices and settings, and there ar...
