【摘要】：隨著網(wǎng)絡(luò)技術(shù)的飛速發(fā)展以及芯片處理能力不斷提升,用戶對(duì)機(jī)頂盒使用需求越來(lái)越多,使用體驗(yàn)越來(lái)越高。機(jī)頂盒作為家用電器類(lèi),不同于實(shí)質(zhì)上已成為快消品的手機(jī),可以通過(guò)直接淘汰舊機(jī)另置新機(jī)的方式來(lái)滿足用戶需求,這時(shí)保留硬件而持續(xù)不斷的升級(jí)軟件的方式成為了機(jī)頂盒行業(yè)最方便最經(jīng)濟(jì)的選擇。本文以四川金網(wǎng)通電子科技有限公司生產(chǎn)的基于海思Hi3716MV300主芯片的DVB+OTT機(jī)頂盒為硬件開(kāi)發(fā)平臺(tái)。軟件開(kāi)發(fā)平臺(tái)為L(zhǎng)inux 2.6操作系統(tǒng),該系統(tǒng)為經(jīng)過(guò)裁剪了一些機(jī)頂盒上不常用到的功能的版本。本文對(duì)機(jī)頂盒中常用的幾種升級(jí)方式都做了詳細(xì)的闡述,包括USB升級(jí)、TS流升級(jí)和網(wǎng)絡(luò)升級(jí)的詳細(xì)設(shè)計(jì)、實(shí)現(xiàn)及測(cè)試修改。本文的目標(biāo)是在選定的硬件平臺(tái)上將這三種機(jī)頂盒軟件升級(jí)方式都設(shè)計(jì)并實(shí)現(xiàn)出來(lái)。USB升級(jí)方式是在開(kāi)機(jī)時(shí)插入U(xiǎn)SB存儲(chǔ)設(shè)備,開(kāi)機(jī)時(shí)能檢測(cè)到升級(jí)信息后進(jìn)入loader開(kāi)始USB升級(jí);TS流升級(jí)方式是只要前端播放升級(jí)流,機(jī)頂盒無(wú)論是開(kāi)機(jī)時(shí)還是開(kāi)機(jī)后都能檢測(cè)到升級(jí)信息,滿足升級(jí)條件則進(jìn)入loader進(jìn)行OTA升級(jí);網(wǎng)絡(luò)升級(jí)方式是在機(jī)頂盒連接上網(wǎng)絡(luò)后,主動(dòng)去服務(wù)器上獲取升級(jí)信息,檢測(cè)到符合條件的升級(jí)信息后,進(jìn)行網(wǎng)絡(luò)升級(jí)。本文使用模塊化設(shè)計(jì)方法,將研究的內(nèi)容分為升級(jí)信息檢測(cè)模塊、數(shù)據(jù)下載模塊、升級(jí)數(shù)據(jù)寫(xiě)入模塊、升級(jí)安全保障模塊和升級(jí)輔助模塊。把各個(gè)模塊都實(shí)現(xiàn)之后和整個(gè)機(jī)頂盒系統(tǒng)一起進(jìn)行綜合調(diào)試,確認(rèn)軟件滿足設(shè)計(jì)要求后,將機(jī)頂盒投入市場(chǎng),去接受市場(chǎng)和用戶考驗(yàn),根據(jù)市場(chǎng)反饋不斷修正完善。
[Abstract]:With the rapid development of network technology and the improvement of chip processing ability, users need more and more set-top boxes and experience more and more. Set-top box, as a kind of household appliances, is different from mobile phones, which have become fast consumables in essence, and can meet the needs of users by directly eliminating the old ones and installing new ones. This is the most convenient and economical choice for the set-top box industry to retain hardware and continuously upgrade the software in a way that has become the most convenient and economical choice for the STB industry. In this paper, the DVB OTT set-top box based on Hayes Hi3716MV300 main chip produced by Sichuan Jinnetong Electronic Technology Co., Ltd is used as the hardware development platform. The software development platform is Linux 2.6, which cuts down some of the features that are not commonly used on the set-top box. In this paper, several kinds of upgrading methods commonly used in STB are described in detail, including the detailed design, implementation and test modification of USB upgrade, TS stream upgrade and network upgrade. The goal of this paper is to design and implement the three upgrade methods of STB software on the selected hardware platform. The upgrade mode is to insert the USB storage device at the boot time, and then can detect the upgrade information and start the USB upgrade by entering the loader when the upgrade information is started. The upgrade mode of TS stream is that as long as the front end plays the upgrade stream, the set-top box can detect the upgrade information when it is turned on or after the start-up, and if the upgrade condition is satisfied, it will enter the loader for OTA upgrade; After the set-top box is connected to the network, the network upgrade mode is to actively go to the server to obtain the upgrade information, and detect the qualified upgrade information, then carry on the network upgrade. In this paper, the research contents are divided into upgrade information detection module, data download module, upgrade data write module, upgrade security module and upgrade auxiliary module by using modular design method. After each module is realized and the whole set-top box system is debugged, after confirming that the software meets the design requirements, the set-top box is put into the market to accept the test of the market and users, and the system is constantly revised and perfected according to the market feedback.
