Abstract

The invention discloses a network projection machine which is free from adopting a computer as a projection source, and is provided with a projection main body, a signal processing liquid crystal drive, an operation display interface and a control key, wherein the projection main body consists of a light source, an optical glass piece, a liquid crystal display (LCD) and a lens; the signal processing liquid crystal drive is used for receiving an inputted video signal and for outputting video graph data to be decoded of the signal to the LCD; the operation display interface is used for displaying a current working status and an operating status of the projection main body; the control key is used for inputting an operation order to the projector; and the network projection machine is also provided with a network interface and a network playing module; and the network interface is used for being connected with an external network, and the network playing module is used for receiving a network data packet from an external network interface, decoding the network data packet into a corresponding video signal and outputting the video signal to the signal processing liquid crystal drive. Due to the adoption of the network projection machine, the large-screen playing problem of a network movie and a video can be solved, the operation procedures can be simplified, and the system circuit connection can be simplified.

Description

technical field [0001] The invention relates to projection equipment, in particular to a network projector. Background technique [0002] Along with people's pursuit of quality of life, people hope to appreciate through big screen when enjoying online movie, usually, the solution mode of prior art has following two kinds: one is to realize by computer connection big-screen flat-panel television; The second is to connect the computer to the projector to achieve. For the first solution, there must be a computer that can connect to the Internet, and the price of a large-screen flat-panel TV is too high, and the cost of the entire system is very high; Only a computer can be used for correct operation, and the system connection is complex, and the image signal and sound signal must be transmitted from the computer to the TV through a dedicated signal line, which is inconvenient for wiring; the screen size is fixed. For technical solution 2, it is also necessary to have a comput...
