Abstract
The utility model discloses a power video transmitter which is formed by a video transmitting device and a video receiving device. The video transmitting device is installed in a casing and is internally provided with an image compression coding circuit which is connected with an audio and video signal input end and a first power modem, and a video signal is decoded and sent through the power modem. The video receiving device is installed in the casing and is internally provided with a second power modem to receive the video signal send by the first power modem, the second power modem is connected to the image compression coding circuit for decoding, and the image compression coding circuit is connected to a signal amplifying circuit and then is connected to an audio and video output end. According to the power video transmitter of the utility model, the difficulty of video transmission wiring in furniture is reduced, and the portability in use is raised.
Description
Technical field
The utility model relates to a kind of video transmitter based on power supply, belongs to the electric component technical field.
Background technology
Antenna or the outside signal supply digital television case of cable reception that existing TV sees through digital television case carry out the signal treatment conversion, at last image is played on the video screen, because digital television case is placed on the video screen top usually, need to use the connecting line that adds to connect, and be subject to the length of connecting line in distance, bring inconvenience.
Summary of the invention
At the defective of prior art, the utility model discloses a kind of power supply video transmitter, realize video signal transmission based on the power line, thereby reduced the home cabling difficulty.
For achieving the above object, the utility model is achieved through the following technical solutions:
Power supply video transmitter, formed by video transmission device and video receiving apparatus, video transmission device wherein, be installed in the housing, be provided with the image compression coding circuit in video transmission device inside, be connected to audio-visual video input signals end, and connect the first electric power cat, the vision signal coding is transferred out by the first electric power cat; Video receiving apparatus is installed in the housing, is provided with the second electric power cat in this video receiving apparatus inside, receive the vision signal that the first electric power cat sends, be connected to the decoding of image compression coding circuit, image compression coding circuit is connected to signal amplification circuit, is connected to audio-visual video output terminals.
Pass through such scheme, the image compression coding circuit receives the vision signal of input, be transferred to the second electric power cat through the coding back by the first electric power cat, the signal that the second electric power cat receives carries out signal through signal amplification circuit after through the decoding circuit decoding and amplifies and strengthen, and the TV, computer etc. that are transferred to terminal are then play.Because whole signals transmission is to rely on power line to realize, has significantly enlarged the transmission range of video, has reduced the wiring difficulty.
Preferably, the described first electric power cat, the second electric power cat are connected to same ammeter, and the same power cat of a built-in same brand of needs matches and gets final product in this case.
In the utility model, audio-visual video input signals end can be various signal ends such as various wireless television signals, cable TV signal, satellite TV signal, and audio-visual video output terminals can be TV, computer screen etc.
Description of drawings
Fig. 1 is the structure chart of the utility model power supply video transmitter.
Embodiment
With reference to the accompanying drawings 1, power supply video transmitter of the present utility model, video transmission device is installed in the housing 181, video transmission device has image compression coding circuit 182, be connected to audio-visual video signal input terminal 183, connect the first electric power cat 184 again, the vision signal coding is transferred out by the first electric power cat 184; Video receiving apparatus is installed in the housing 201, and video receiving apparatus is provided with image compression coding circuit 202, connect to receive the second electric power cat 203, in order to the receiver, video signal, outputs signal to and televises thereby connect signal amplification circuit 204 again.
Wherein, the first electric power cat, the second electric power cat all are connected same ammeter 30 times.
