【摘要】：隨著“寬帶中國”和“三網(wǎng)融合”戰(zhàn)略的深化,帶寬已不再成為瓶頸問題,人們對超高清、4K視頻等其他娛樂活動的日益增長的需求,傳統(tǒng)的Linux機頂盒無法滿足需求,搭載Android系統(tǒng)的智能機頂盒應(yīng)運而生。Android系統(tǒng)具有開源、應(yīng)用豐富、二次開發(fā)容易等優(yōu)點,不僅應(yīng)用于智能手機領(lǐng)域,還移植到可穿戴設(shè)備、機頂盒領(lǐng)域。由于運營商業(yè)務(wù)更新,或修復(fù)原有系統(tǒng)缺陷,提升機頂盒系統(tǒng)性能等,機頂盒需要通過升級進(jìn)行相應(yīng)更新。如何確保升級的可靠、穩(wěn)定和高效,因而智能機頂盒的升級研究顯得十分重要。本文基于已有的基礎(chǔ)上,研究了Android機頂盒的系統(tǒng)架構(gòu)和升級所用的關(guān)鍵技術(shù),重點研究了本地升級USB升級和網(wǎng)絡(luò)升級流程及原理�；诩儥C頂盒升級基礎(chǔ)上,實現(xiàn)了智能網(wǎng)關(guān)機頂盒的升級,核心思想是在機頂盒升級過程中加入對網(wǎng)關(guān)升級包的相應(yīng)處理。在智能網(wǎng)關(guān)機頂盒中,機頂盒搭載Android系統(tǒng),網(wǎng)關(guān)搭載Linux系統(tǒng),通過相互通信,可以實現(xiàn)雙系統(tǒng)的升級。既可以單獨進(jìn)行機頂盒系統(tǒng)升級或網(wǎng)關(guān)升級,又可以進(jìn)行機頂盒和網(wǎng)關(guān)二者混合的升級。經(jīng)過多次測試,智能網(wǎng)關(guān)機頂盒的升級過程運行穩(wěn)定、可靠,達(dá)到預(yù)期效果,同時兼容了原有智能機頂盒的升級,在實際過程中已經(jīng)得到應(yīng)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.
