【摘要】：随着“宽带中国”和“三网融合”战略的深化,带宽已不再成为瓶颈问题,人们对超高清、4K视频等其他娱乐活动的日益增长的需求,传统的Linux机顶盒无法满足需求,搭载Android系统的智能机顶盒应运而生。Android系统具有开源、应用丰富、二次开发容易等优点,不仅应用于智能手机领域,还移植到可穿戴设备、机顶盒领域。由于运营商业务更新,或修复原有系统缺陷,提升机顶盒系统性能等,机顶盒需要通过升级进行相应更新。如何确保升级的可靠、稳定和高效,因而智能机顶盒的升级研究显得十分重要。本文基于已有的基础上,研究了Android机顶盒的系统架构和升级所用的关键技术,重点研究了本地升级USB升级和网络升级流程及原理。基于纯机顶盒升级基础上,实现了智能网关机顶盒的升级,核心思想是在机顶盒升级过程中加入对网关升级包的相应处理。在智能网关机顶盒中,机顶盒搭载Android系统,网关搭载Linux系统,通过相互通信,可以实现双系统的升级。既可以单独进行机顶盒系统升级或网关升级,又可以进行机顶盒和网关二者混合的升级。经过多次测试,智能网关机顶盒的升级过程运行稳定、可靠,达到预期效果,同时兼容了原有智能机顶盒的升级,在实际过程中已经得到应用,效果反映良好。
[Abstract]:With the deepening of the strategy of "broadband China" and "three-network convergence", bandwidth is no longer a bottleneck problem, and there is increasing demand for other entertainment activities such as ultra-high definition 4K video. Traditional Linux set-top box can not meet the demand. The intelligent set-top box with Android system emerges as the times require. Android system has the advantages of open source, rich application, easy secondary development and so on. It is not only used in the field of smart phones, but also transplanted to wearable devices and set-top boxes. Due to the business renewal of operators, or to repair the original system defects, improve the performance of set-top box system, and so on. The set-top box needs to be updated by upgrading. How to ensure the reliability, stability and efficiency of the upgrade, so the intelligent set-top box upgrade research is very important. This paper based on the existing basis. This paper studies the system architecture of Android set-top box and the key technologies used in upgrading, and focuses on the local upgrade process and principle of USB upgrade and network upgrade, based on the pure set-top box upgrade. The core idea is to add the corresponding processing to the gateway upgrade package in the process of upgrading the intelligent gateway set-top box. In the intelligent gateway set-top box, the set-top box carries the Android system. The gateway is equipped with Linux system, which can realize the upgrade of dual system by communicating with each other. Either the set-top box system can be upgraded or the gateway can be upgraded separately. After many tests, the upgrade process of the intelligent gateway set-top box is stable, reliable, and achieve the desired results. At the same time, it is compatible with the upgrade of the original intelligent set-top box. It has been applied in practice, and the effect is good.
