The present invention relates to an encoder, and more particularly, to an encoder with touch screen.
Now live stream is just like a raging fire, and professional live streams for web casting, enterprise event, conference, government, sport and church event are very popular. The principle of the professional live stream is to connect a video camera (or media source) to an encoder and stream it to a live platform after the network (wireless, 4G, or wired network) is connected. Wherein, the core technology of the live stream is the encoder, and the existing encoders all need to cooperate with streaming software and operate with a computer or a mobile phone, and users also need to set relevant parameters of the existing encoders. For the user who does not have live stream experience, it is easy to have a live stream accident. Therefore, we create this machine that integrates monitoring, encoding, switching and streaming in one.
In view of the shortcomings of the above-mentioned solution, the present invention provides an encoder with touch control, good heat dissipation effect and capable of working in a wireless network.
A technical solution of the present invention is: an encoder with touch screen including a shell body, and a printed circuit board (PCB board) being disposed in the shell body. The shell body is provided with a touch screen, and the PCB board is provided with a processor, an audio decoder, a video converter, a 4G module, a Flash memory and a memory module. The processor includes an IIS interface, an IIC interface, an HDMI IN interface, an HDMI OUT interface, an Mipi (i.e. mobile industry processor interface) Out interface, a GMAC interface, a FLASH0 eMMC interface and a DDR3 interface. The IIS interface and the IIC interface are connected with the audio decoder, respectively, the HDMI IN interface is connected with the video converter, and the Mipi Out interface is connected with the touch screen. The GMAC interface is connected with an RJ-45 cable interface through an RGMII interface, the FLASH0 eMMC interface is connected with the Flash memory, and the DDR3 interface is connected with the memory module.
Preferably, the PCB board may be further provided with a WIFI module, the processor may further include an SDI00 UART0 interface, and the SDI00 UART0 interface may be connected with the WIFI module.
Preferably, the PCB board may be further provided with a 4G module, the processor may further include a USB HOST communication interface, and the USB HOST communication interface may be connected with the 4G module.
Preferably, the PCB board may be further provided with a switching regulator, and the processor may further include a PWR Supply interface. The PWR Supply interface may be connected with the switching regulator, and the switching regulator may be connected with a power supply output end.
Preferably, a graphite heat sink may be attached to the PCB board.
Preferably, the graphite heat sink may be attached to a rear inner wall of the shell body.
Beneficial effects of the present invention are: the encoder can be touch-controlled by adopting the touch screen; the heat dissipation effect is good by setting the graphite heat sink; the encoder can work in the wireless network by setting the WIFI module and the 4G module; and the working is stable by setting the switching regulator.
The present invention will be further described in detail below with reference to the accompanying drawing and specific embodiment.
The technical solution of the present invention will be further described below with reference to the accompanying drawing, but the present invention is not limited to these embodiments.
Combining with
The IIS interface and the IIC interface are connected with the audio decoder, respectively, and the audio decoder is provided with an audio input interface and an audio output interface. The HDMI IN interface is connected with the video converter, the video converter is provided with a video input interface, and the video input interface is connected with a video output interface of the camera. The UART2 interface is connected with a DEBUG UART interface as a debug serial port. The Mipi Out interface is connected with the touch screen to carry out touch setting. The GMAC interface is connected with an RJ-45 cable interface through an RGMII interface, and the RJ-45 cable interface is connected with equipment such as a server and so on to push video and audio. The FLASH0 eMMC interface is connected with the Flash memory. The DDR3 interface includes a DDR3 32 bit 0 Channel interface and a DDR3 32 bit 1 Channel interface. The DDR3 32 bit 0 Channel interface and the DDR3 32 bit 1 Channel interface are connected with the memory module, respectively. The SDI00 UART0 interface is connected with the WIFI module to push video and audio in the wireless network. The USB HOST communication interface is connected with the 4G module to push video and audio in the wireless network. The PWR Supply interface is connected with the switching regulator, and the switching regulator is connected with a power supply output end and has the effect of voltage regulation.
