Shown in Figure 1, in the present embodiment, the MEMC part 100 in described end product adopts the design of platelet board-splicing type, and flexibility is good, and design and making are easier.
The invention solves following problem:
(1) the video data real time access technology of magnanimity
In Video Applications, traditional storage means is to adopt the modes such as front-end stores, centralized stores, the network storage; Along with " progressively maturation and the commercialization of cloud computing technology adopt the cloud memory technology to provide video access technique highly reliable, high expansion for the user.The video/audio that intelligent terminal produces has the characteristics that data volume is large, playback needs real time access usually, when video user is many, guarantee that there is larger difficulty in user's real time access, may bring larger delay.The present invention utilizes the high in the clouds resource, and the real time access interface of design specialized adopts multi-level buffer, sequence, classification, looks ahead, the multiple means such as location fast, reaches the accessible effect such as vertical.
(2) operation system of cloud television set intelligently terminal is supported in research and development
Intelligent terminal need to be set up supporting operation system, comprising: content service provider's interface, user terminal interface, the content of cooperating with the content service provider are accelerated system and Network function.Its design comprises: server allocation plan, Web service architecture design, Internet service, administration module etc.The present invention can simultaneously in the face of the different terminals such as TV and mobile phone provide service, in the designs such as service discovering, business navigation and business represent, guarantee to obtain when accessing by different types of terminals to the user consistent business experience.In addition, system satisfies the requirement of different types of terminals, can support different code streams, different resolution, and the broadcast of the media content of different coding form and download are for the user provides media content Play Control with online or local broadcast form.
(3) core
The system core take MSD6A801 as main body is partly the first key technology of the present invention, MSD6A801FVA single-chip integrated network, digital-to-analogue demodulation, PHY, 2D turn the 3D module in the one function, built-in chip type full system type pictorial colour decoder, acoustic processing module, video processor, Scaler, ADC, 3D-DEINTERLACE, PHY, MCU, HDMI etc.; The input of kilocalorie and two-way TS stream, one road TS stream output are supported in built-in DVB-C decoding; Support MPEG2 audio/video decoding, MPEG-4 video decode, H.264 video decode, MVC decoding, RealMedia decoding; MPEG4, H.264 the coding, the CVBS Video coding; Nand Flash controller, MAC, Miscellaneous etc.
(4) eMMC part
EMMC (Embedded MultiMediaCard) is the ordered embedded memory standards specification of MMC association, and its integrated controller in encapsulation provides standard interface and manages flash memory.Physical interface is simple, 8 DATA pin only, and 1 CLK pin, a CMD pin, the operation debugging is simpler.Adopt small-sized BGA encapsulation, pad pitch only has 0.5mm, and than original master chip, the 0.8mm such as DDR are little, and are higher to the requirement of technique, and interface rate is up to per second 52MB, and PCB layout need to be careful impedance matching.
(5) 6A801 core power pack
The core of 6A801 power supply 1.1V electric current is larger, because producer does not also complete the test of electric current, and system is when running Android and using, and the electric current changes in demand is large.Therefore, reliable in order to guarantee power supply, integrated cost is considered, the BUCK circuit that the present invention adopts " controller+external MOS " scheme namely to separate only needs to adjust peripheral MOS, and the specification of inductance is the capable of regulating supply current.RT8110 is a single channel synchronous buck controller of RICHTEK company, forms synchronous buck framework, built-in overcurrent protection and under-voltage protection function by driving outside two metal-oxide-semiconductor.Adopt the mode of controller, adopt at present two N-channel MOS pipes of pine ME4970 S0P8 encapsulation, inductance 4.7u, electric current 5A.
(6) SD card portion
The integrated SD card interface of main IC does not need external GL823 to convert USB to, but due to main IC pins limits, SD data line card and PCMCIA data wire are multiplexing.
(7) PCB layout and EMI thereof
This programme uses single doubling plate jigsaw form, with AV for falling Cost Design, YPbPr, the cablings such as SPDIF require lower terminal to line up the individual layer platelet, use mother daughter board connector to connect mainboard, not only reduce costs from sheet material, the pcb board area also greatly reduces, and has reduced cost; For falling cost and improving whole aircraft reliability and manufacturability, LVDS has kept FFC, 2 sockets of general LVDS seat simultaneously; Simultaneously this scheme is used many bga chips, and 953 pins of master chip are realized with doubling plate, is not only a huge challenge satisfying aspect signal integrity, exactly all signal inputs, output master chip is had great difficulty.Reduce isolating of bottom as far as possible in device layout, cabling, guarantee the complete of bottom ground.Rationally wrap ground in cabling, in DDR cabling assurance group, track lengths is consistent.LVDS holding wire length is as far as possible consistent.The RF signal of Silicon tuner is tried one's best short and thick, and the cabling that reduces tuner disturbs, and the IF cabling is avoided via hole as far as possible.
The present invention take the existing network TV as the basis, by adopting more high performance chip, make it to have the multi-task parallel disposal ability, take complete operating system and full open model operating platform as base layer support, by integrating the functional software of various application programs and third party exploitation, the user can search for various contents and application software and freely select and install or uninstall, obtains the unlimited ability of expanding.The adequate and systematic service system is also on existing network TV service system basis, on the basis of the service functions such as the information that keeps the legacy network TV, audio-visual, game, education, Karaoke, map, increase application program shop function, allow the third party to upload the application program that meets standard, the user can freely select to download and install or unload application program.On the intelligent terminal basis, utilize the technology such as cloud computing, cloud storage, simultaneously set up strategic partnership relationship with R﹠D institution, colleges and universities and service provider widely, realize the emphasis characteristic services such as on-line payment, social TV and multi-screen interactive, and various cloud TV service.Take full advantage of the multicast feature of IPv6, realize Source-Specific Multicast and scope multicast; Adopt IGRS standard to develop the multi-screen interactive business, make the terminal of this project and the interaction between domestic other manufacturer's product that maximum compatibility can be arranged.The embedded OS of optimizing is optimized aspects such as memory space, power management and startups, has obtained effect preferably, obtains more superior cloud television set intelligently end product.
