Design And Research Of SMART TV Module Based On Android Platform

TV development contains two times:the era of analog television era and digital era。In analog television era, television in system mainly based on hardware software as a supplement, the basic software depends on the microcontroller simple behavior control。The signal transmission and the output is the simulation, such as output by CRT scan, ATV RF signal transmission。This stage is unable to realize human-computer interaction intelligent functions。Change of digital era TV mainly changes in the input and output signals and application requirements, such as the DTV signal by using LED display、HDMI signal、 LVDS signal transmission、network application interaction etc。Requirements for the software of the digital age grow with each passing day, the software system consists of single chip computer ARM to the Linux system, and then to the general Android system along with the changing market demand balance。 The Android system software architecture into the digital era mainstream based on Android platform is based on each level is relatively clear, also can follow the market random changes greatly meet various user requirements。 Smart TV Android system can meet the requirements of various signal analysis based on network application, especially in the end, the user use become possible。This paper describes an Android software system based on MTK5505chip to create functional intelligent, modular system, using the methodology described will maximize the software system independent, modular, intelligent, capable of quick and convenient fast transposition in various hardware platform。 In this paper, the Android software module form independent design and module is studied in detail, the main research content includes three aspects:1、Introduces the design content and method of intelligent TV module design, main source o2、Using the MTK5505hardware platform as the core, the paper studied the LED55K610X3D series TV hardware, software system module solution, analysis, from product PRD and the application end function requirements of Launcher UI are described in detail。Secondly, detailed on the module interface requirements such as WIFI、DLNA、Media player、TV Sleep、Backlight、3D、DTV、ATV、Remote、 DTMB、OTA、EPG technical parameters of the decomposition。3、Described in the paper introduces intelligent software module design process in some abnormal data processing method and method of software system development environment and test。...
