发布时间：2018-12-12 04:10
【摘要】：数码产品日新月异，总是以迅雷不及掩耳之势改变着我们的观看习惯，从早期的DVD、蓝光机，到现代的Wi-Fi display、DLNA等无线技术的实现，智能化逐步走进人们的生活，而TV box(电视盒)的出现进一步改变了我们看电视的方式。目前， TV box的产业链已经形成，，有大量的厂商开始生产中国版本的TV box。 针对人们对数码产品的智能化、多样化的要求越来越高，本课题选择以智能TV box系统为研究目标。通过对目前市场上主流的嵌入式处理芯片和操作系统的比较，选择以高能效的Cortex-A7作为系统处理器和市面流行的Android系统作为操作系统，并使用无线传输技术实现了多媒体推送，多屏互动等功能 本课题选用全志公司生产的A31处理器作为主控芯片，AXP221为电源管理芯片，对外扩充了存储电路、Wi-Fi模组、HDMI接口、USB接口和红外接收头等。在主流的TV box基础上增加了基于无线传输技术的应用程序，使TV box与其他Android设备能够通过无线网络传输数据。除此之外，系统还设计了界面友好的Launcher和一系列应用程序，能观看网络电视、也可以听音乐、玩游戏、视频聊天。是一个功能丰富、性能稳定的家庭娱乐产品。
[Abstract]:Digital products are changing with each passing day, always changing our viewing habits with the tendency of fast thunder. From the early DVD, Blu-ray machine to the realization of wireless technology such as modern Wi-Fi display,DLNA, intelligentized step by step into people's life. The emergence of TV box (TV boxes has further changed the way we watch TV. At present, the industrial chain of, TV box has been formed, and a large number of manufacturers have begun to produce the Chinese version of TV box.. In view of the increasing demand for intelligence and diversification of digital products, this paper chooses intelligent TV box system as the research goal. By comparing the mainstream embedded processing chips and operating systems in the market at present, we choose the energy-efficient Cortex-A7 as the system processor and the popular Android system as the operating system. And using wireless transmission technology to achieve multimedia push, multi-screen interaction and other functions this topic selected A31 processor produced by Quanzhi Company as the main control chip, AXP221 as the power management chip, external expansion of the storage circuit, Wi-Fi module, HDMI interface, USB interface and infrared receiver head. An application based on wireless transmission technology is added to mainstream TV box to enable TV box and other Android devices to transmit data over wireless network. In addition, the system also designed a friendly interface Launcher and a series of applications, can watch network television, can also listen to music, play games, video chat. Is a rich function, stable performance of home entertainment products.
