Traditional video booth

Product description

Traditional video booth scheme is widely used in teaching and training, company display and other fields

Core Video Technology provides the main IC-CV1860 for the back-end image processing in the video booth scheme. This IC directly receives digital signals such as 656 from the front-end sensor IC, performs scaling and various image processing methods, and finally converts them into analog VGA signal output through the built-in DAC module. This IC especially provides a series of high-level functions such as frame detection for video booths, which can effectively separate defective frames to maximize the definition of the picture. In the past, it was generally achieved through external FPGA

The digital signal formats that CV1860 can directly process at present include 8-bit 656/601/1120, 16-bit 601, 16-bit or 24-bit YUV/RGB signals. The maximum resolution of digital input can reach 1920x1080. The core scaler supports true 1080P60 level scaling. The analog VGA output resolution can reach 1920x1200. The built-in TV Encoder module supports CVBS and S terminal output! In addition, its analog VGA output and digital output support simultaneous output at the same resolution

CV1860 has a built-in OSD with complete functions. The Chinese and English characters or graphics required by users are drawn in the form of dot matrix in advance and saved as a library file. This library file and the software are stored in the FLASH of the external MCU. After power-on and startup, the software can be transferred to Memory for free use. The OSD can be displayed in full screen, and can also be easily moved to any position on the screen. When moving the OSD, you can directly specify a new display coordinate value, There is no need to refresh pixels

CV1860 needs an external MCU to control it. This MCU works through the I2C bus. It is an ordinary 51 series MCU. The required FLASH space depends on the complexity of the user's OSD. Generally speaking, the space required for various settings of CV1860 itself is about 4K

CV1860 requires an external memory, with the specification of 4x32 bits and 8M bytes of SDRAM, and the main frequency of 160MHZ

The CV1860 has a power consumption of about 1.5W at full speed at the highest 1080P60 level, and the chip surface temperature is about 37 degrees. It does not need an external radiator, and can support 7x24 hours of industrial operation

Core Video Technology provides CV1860 chip data, software development bottom settings, samples and development tools for free. As for the upper specific applications of the video booth, such as multi-picture comparison and other software application functions, users need to develop them by themselves. At present, the finished products of several video booth manufacturers supported by Core Video Technology have been mass produced and listed, and their cost performance ratio is second to none in the current mainstream booth scheme.
