Fig. 1 is based on the schematic diagram of the Video service scheme of open the Internet in the prior art;
Fig. 2 is the structure principle chart based on the video service device of open the Internet that the utility model embodiment provides;
Fig. 3 is the structure principle chart of the internet television that provides of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
The structure principle chart based on the video service device of open the Internet that Fig. 2 shows that the utility model embodiment provides.Video service device based on open the Internet of the present utility model comprises that master chip 21, programming device 22, coding chip 23, RGB change HDMI chip 24 and WiFi module 25; Wherein, master chip 21 connects programming device 22, coding chip 23 and WiFi module 25 respectively, programming device 22 connects coding chip 23 respectively and RGB changes HDMI chip 24, master chip 21 is connected with coding chip 23 with the SDIO bus by the I2C bus respectively, and master chip 21 also changes HDMI chip 24 by the I2C bus with RGB and is connected.
Optionally, master chip 21 is connected programming device 22 by 18 RGB data wires with an I2S bus, programming device 22 is connected coding chip 23 by 18 RGB data wires with an I2S bus, programming device 22 also connects RGB by 18 RGB data wires and an I2S bus changes HDMI chip 24, above-mentioned RGB data wire is used for transmitting rgb signal, the I2S bus is used for transmit audio signals, and what these rgb signals and audio signal were used is Transistor-Transistor Logic level.
Optionally, master chip 21 carries Android4.0 operating system, and integrated double-core Cortex-A9CPU, the built-in 3D Mai400 of double-core Cortex-A9CPU graphic process unit; Programming device 22 comprises field programmable gate array (FPGA) or CPLD (CPLD); Coding chip 23 is for supporting the coding chip of the full HD video of 1080P.
The concrete principle of the video service device based on open the Internet of the present utility model is as follows: master chip 21 receives multi-media signal (being mainly video/audio signal) on the network by network interface, and general's vision signal wherein is decoded into the high definition rgb signal of 1080P60Hz, be sent to programming device 22 together with audio signal then, programming device 22 is divided into two the rgb signal in the video/audio signal that receives, with a road being sent to RGB together with audio signal and changeing HDMI chip 24 wherein, change directly output HDMI1080P60Hz high-definition video signal of HDMI chip 24 by RGB, show by display terminals such as television sets; Because coding chip 23 is not supported the signal of 1080P60Hz, only support the signal of 1080P30Hz, so programming device 22 will fall frame to 30Hz from 60Hz with another road rgb signal, the rgb signal that falls behind the frame is encoded by coding chip 23, return to master chip 21 by the SDIO bus together with audio signal then, sent by WiFi module 25 by master chip 21, thereby realize that the high resolution video and audio signal is in the wireless sharing of home entertainment center.
