Improve as one of the present utility model, two and above high-definition signal receiving terminal can go out chip by sdi signal ring and carry out cascade, support that a high-definition signal transmitting terminal connects a lot of high-definition signal receiving terminals and carries out high-definition video signal teletransmission relay, and then realize the force transfer function of high-definition signal.
Improve as one of the present utility model, described coaxial cable adopts high-frequency resistance to be the coaxial cable in 75 Europe, itself and other electric wire ratio, good to high-frequency signal conductive performance.
Improve as one of the present utility model, native system is supported in the transmission over coaxial cable 1080p high definition HDMI signal in 75 Europe of 100 meters of length
Relative to prior art, the HDMI high-definition signal that PC or player HDMI send mouth output is first converted to HD-SDI signal by the utility model, and is stablized at a distance by the coaxial cable in 75 Europe and reliably transmitted; Go out chip make high-definition signal receiving terminal supporting signal ring go out function owing to have employed sdi signal ring, and then support the force transfer of high-definition signal, realize the signal transfer mode (i.e. high-definition signal transmitting terminal can while corresponding multiple high-definition signal receiving terminal) of one-to-many; In addition, native system also supports slipping into of audio frequency and de-embedding, has the function of audio-visual synchronization transmission.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to deepen understanding and cognition of the present utility model, below in conjunction with accompanying drawing the utility model be further described and introduce.
As shown in Figure 1, a kind of novel
high definitionvideo coaxial cable teletransmission receive-transmit system, comprises high-definition signal transmitting terminal and high-definition signal receiving terminal, and described high-definition signal transmitting terminal is communicated by coaxial cable with high-definition signal receiving terminal.HDMI high-definition signal is converted to HD-SDI signal transmit at a distance on coax.Described high-definition signal transmitting terminal comprises the first microcontroller (MCU1) and the HDMI signaling interface, HDMI signal conversion chip, the sdi signal that are connected by data wire with the first microcontroller (MCU1) send chip and the first bnc interface, and described high-definition signal receiving terminal comprises the second microcontroller (MCU2) and the second bnc interface, sdi signal receiving chip and the HDMI signal that are connected by data wire with the second microcontroller (MCU2) send chip.
HD-SDI signal is high-definition digital component interface, and have high-definition image without delay real-time Transmission, high-definition image is without compressing the advantages such as undistorted, the high-definition signal of transmission 1080p reliable and stable on single 100 meters of length coaxial cables.
First, high-definition signal source (computer or player HDMI transmitting terminal) exports the HDMI signaling interface of high-definition signal to high-definition signal transmitting terminal, the audio signal arriving the vision signal and I2S form that HDMI signal conversion chip is converted to Transistor-Transistor Logic level is again input to sdi signal again and sends chip, and the HD-SDI signal being processed into standard through sdi signal transmission chip exports from the first bnc interface.
The coaxial cable that second bnc interface of high-definition signal receiving terminal connects common 75 100 meters of length in Europe receives the sdi signal sended over, and being input to the process of sdi signal receiving chip, the audio signal exporting TTL digital video signal and I2S is input to HDMI signal again and sends the HDMI signal that chip carries out the standard that converts to and output to display device.
Simultaneously sdi signal receiving chip also will receive sdi signal and does hoop and go out process and export, and the sdi signal that ring goes out directly can access next high definition teletransmission receiving terminal processes and displays, and the high-definition signal realizing one-to-many transmits.
