Radio and TV HD all-in-one machine

Abstract

The invention provides a radio and television high-definition all-in-one machine, which comprises an FPGA processing unit and is characterized in that SDI input channels 0-15 of the FPGA processing unit are connected to voltage and impedance balance modules respectively, PC output is connected to the FPGA processing unit through a subtitle processing unit; server output is connected to the FPGA processing unit through an IP decoder unit; a synchronization module transmits SDI signals to the FPGA processing unit, and an MCU module is connected to the FPGA processing unit through a serial SPI-BUS bus interface. According to the radio and television high-definition all-in-one machine, a chip design principle and an idea of independent innovation are adopted, the integration level of a system is enabled to be higher, the independent technology content is higher, and the exploitability and the upgradeability are higher. In addition, connection of the whole product is enabled to be simpler and more convenient, and high performance is maintained under the condition of reducing the total cost. Meanwhile, the design of expansion ports provides a basis for addition of recording, production and IP interfaces.

Description

technical field [0001] The invention relates to the technical field of radio and television, in particular to a radio and television high-definition all-in-one machine. 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 equipment to high-definition equipment is not only expensive but also not stable according to the current equipment market conditions. At the same time, most of the high-definition equipment on the market currently use It is made of proprietary chips. This method has a low integration ...

Problems solved by technology

At present, most domestic TV programs are still in standard definition. The conversion from standard definition equipment to high-definition equipment is not only expensive but also not stable according to the current equipment market conditions. At the same time, most of the high-definition equipment on the market currently use It is made of a proprietary chip. This approach, firstly, the integration level is not high, and the integration stability is not very good. The connection between devices is cumbersome and troublesome. In addition, the price of single-function devices is relatively high.
