Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

The utility model provides a many signal format conversion auto-change over device, including the singlechip, as shown in FIG. 1, in this embodiment, the singlechip adopts the model to be STC80C 51's singlechip, and its peripheral circuit is shown as FIG. 1, and it is no longer repeated here, in addition, what need explain, though the singlechip in this embodiment adopts the singlechip of this model, nevertheless the utility model discloses a protection range is not limited to this, and the singlechip of other models or the microprocessor the same with the singlechip function all are in the utility model discloses a protection range.

The single chip is connected with an HDMI receiver, as shown in fig. 2, in this embodiment, the HDMI receiver is a receiver with a model of IT6605, the IT6605 is a dual-port HDMI receiver, is fully compatible with HDMI 1.3, is compatible with HDMI 1.4a 3D and HDCP 1.4, and is backward compatible with DVI 1.0 specification, the IT6605 has a deep color function (36 bits at the highest), and can ensure reliable reception of high-quality uncompressed video content, and most advanced uncompressed and compressed digital audio content in digital televisions and projectors, such as DTS-HD and Dolby TrueHD. IT6605 also supports all major 3D formats that are compatible with the HDMI 1.4a 3D specification.

As shown in fig. 3 to 6, the HDMI receiver is connected to a DIV interface, an HDMI interface, a VGA interface, and a BNC interface, and can convert and output data in the interfaces, so that data conversion in various transmission modes can be realized, and various types of signal input and output are supported.

In addition, the single chip microcomputer is also connected with an RS-232 communication module, as shown in fig. 7, the RS-232 communication module adopts an MAX232 chip, converts the TTL level output by the single chip microcomputer into a 232 level that can be received by a PC or converts the 232 level output by the PC into a TTL level that can be received by the single chip microcomputer, and controls the TTL level through an RS232 port.

Further, the HDMI receiver is connected to a memory, as shown in fig. 8, in this embodiment, the memory is a charged erasable programmable read only memory of AT24C02, the AT24C02 supports I2C, and the bus data transfer protocol I2C specifies any device that transfers data to the bus as a transmitter.
