技术领域
本申请实施例涉及但不限于机顶盒技术领域，尤指一种信息获取方法、云化机顶盒系统、实体机顶盒及存储介质。
背景技术
随着大视频业务日益发展成熟，机顶盒(STB，Set Top Box)用户对业务体验提出了更高的要求，希望能够通过大视频业务享受更好的用户界面(UI，User Interface)体验，享受更丰富的增值业务，丰富日常生活；而且，随着固网宽带提速、光纤到户和无线4G普及、5G的到来，大视频业务将迎来大发展时期，具有较广阔的应用场景。
在大视频业务快速发展的同时，也面临诸多问题：智慧家庭业务的发展越来越丰富，对STB硬件要求越来越高，而现网存量STB不能满足智慧家庭发展的需求；STB型号多，对新业务、新需求的适配成本高、部署周期长、运维成本高，不能满足业务互联网化、快速迭代的需求；新UI、新业务体验对STB性能要求较高，现网存量STB由于各种原因无法提供新UI、新业务体验，导致新老STB体验不一致。随着时间的推移，STB型号越来越多，以上矛盾会越来越突出，如果对现网STB进行更换，成本特别高。
针对上述问题，目前提出了云化STB的解决方案。然而，在目前的云化STB方案中，针对大数据量的业务(比如，大视频业务)，实体机顶盒(tSTB)与云端虚拟机顶盒(vSTB)之间没有有效的信息交互和获取方式，比如，tSTB 上的本地应用和vSTB上的云化应用为了实现正常交互，需要进行大量的定制修改，实现方式复杂。

在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
本申请实施例提供一种云化机顶盒系统，包括：实体机顶盒以及运行有实体机顶盒对应的云端虚拟机顶盒的服务端；其中，实体机顶盒与云端虚拟机顶盒之间建立业务代理通道；实体机顶盒通过第一代理服务模块，经由业务代理通道与云端虚拟机顶盒进行交互，以获取信息；云端虚拟机顶盒通过 第二代理服务模块，经由业务代理通道与实体机顶盒进行交互，以获取信息。本申请实施例通过第一代理服务模块和第二代理服务模块在实体机顶盒与云端虚拟机顶盒之间实现信息交互，可以支持实现无云化感的大数据量业务的信息获取，从而提高用户体验。
图1为本申请实施例提供的云化机顶盒系统的一种示例图。如图1所示，本实施例提供的云化机顶盒系统包括：实体机顶盒(tSTB)、云平台(对应上述的服务端)以及业务系统(比如，内容分发网络(CDN，Content Delivery Network)、电子节目指南(EPG，Electronic Program Guide)等)。云平台上运行有虚拟机顶盒(vSTB)管理器(Manager)以及给tSTB分配的一个或多个云端vSTB。
其中，在tSTB中运行有tSTB云客户端，tSTB云客户端中包括t端代理模块(对应上述的第一代理服务模块)；t端代理模块包括云化应用代理单元以及代理执行单元Hub，用于给tSTB的大数据业务的信息传输提供代理服务。其中，由于一个tSTB可以对应多个云端vSTB，因此，t端代理模块可以根据需求与对应的云端vSTB相关。
其中，tSTB对应的云端vSTB中运行有云化应用以及v端代理模块(对应上述的第二代理服务模块)；v端代理模块包括本地应用代理单元以及代理执行单元Hub，用于给vSTB的大数据业务的信息传输提供代理服务。
其中，t端代理模块的代理执行单元Hub和v端代理模块的代理执行单元Hub之间可以建立业务代理通道，以支持本地应用代理单元和云化应用代理单元之间通过业务代理通道进行信息交互。
其中，tSTB上还运行有Spice(Simple Protocol for Independent Computing Environments，一种用于虚拟化环境中的通讯协议)客户端(Client)，云端vSTB上运行有Spice服务器(Server)；Spice客户端和Splice服务器之间可以建立桌面通道，比如，用于传输桌面指令等。
在图1中，tIF表示实体机顶盒内部的接口；其中，tIF1表示本地应用与云化应用代理单元之间的接口，tIF2表示tSTB云客户端与安卓(Android)系统之间的接口，tIF3表示t端代理模块内的本地应用代理单元与代理执行单元Hub之间的接口。vIF表示云端虚拟机顶盒内部的接口；其中，vIF1表示云化 应用与本地应用代理单元之间的接口，vIF2表示云化应用与安卓(Guest OS Android)系统之间的接口，vIF3表示v端代理模块内的本地应用代理单元与代理执行单元Hub之间的接口。sIF表示实体机顶盒与云平台之间的接口；其中，sIF1表示tSTB与云端vSTB管理器之间的接口，sIF2表示Spice Client与Spice Server之间的接口，sIF3表示tSTB的代理执行单元Hub与vSTB的代理执行单元Hub之间的接口。
在本实施例中，tSTB可以通过云化认证系统接入云平台，在tSTB通过认证后，由云平台的vSTB Manager给tSTB分配对应的一个或多个云端vSTB。其中，云端vSTB上运行的云化应用可以保持原有交互方式及接口调用不变，通过业务代理通道，实现与tSTB上的本地应用的交互，进行信息获取。tSTB接收来自业务代理通道的交互请求后，同样可以通过原有交互方式及接口调用，对交互请求进行处理，从而实现与云端vSTB的信息交互。其中，云端vSTB上的云化应用保持原有交互方式及接口调用，因此，不管应用运行在本地还是云端，对云化无感。系统接口层实现将应用交互请求，通过绑定对应的代理服务，由业务代理通道进行传输。云化应用代理单元和本地应用代理单元需要向业务代理通道进行注册，确保应用交互请求成功被业务代理通道进行传输。在tSTB连接上云端vSTB后，业务代理通道需要一直保活在线。
在本实施例中，虚拟化设备、业务云化、用户界面(UI，User Interface)以及部分应用程序(APP，Application)运行在云端vSTB上，以视频流形式下发至实体终端；应用通过业务代理通道实现交互。tSTB可以转发遥控指令、UI展示、媒体播放；支持本地应用和云化应用通过业务代理通道实现交互。
在上述云化机顶盒系统中，对于云端vSTB和tSTB来说，云化应用和本地应用之间的交互可以避免原有交互方式和接口因为云化而进行大量的修改定制，不管是运行本地应用还是云化应用，可以消除云化带来的应用交互影响，实现真正的对云化无感。
图2为本申请实施例中云化应用和本地应用的交互示例流程图。在本实施例中，vSTB和tSTB需各自注册应用代理单元，其中，vSTB注册本地应用代理单元，tSTB注册云化应用代理单元；云化应用代理单元作为云化应用在tSTB的映射存在，本地应用代理单元作为本地应用在云端vSTB的映射存在， 实现两端应用列表透明化。当机顶盒用户进行云端应用操作时，机顶盒通常支持调用原生系统服务(比如，包括AMS(ActivityManagerService)、PMS(PackageManagerService)、媒体、图形、网络、存储等)，支持MediaCodec并扩展支持低延时模式(不缓存帧数据，有解码帧即输出)，同时也支持调用扩展系统服务、系统属性等；被调用的系统服务通过与同端应用代理单元进行绑定，进而由业务代理通道，实现vSTB和tSTB之间的应用交互。
如图2所示，本实施例中的云化应用和本地应用的交互过程可以包括：
S201、当实体机顶盒开机，tSTB成功连接云端vSTB后，业务代理通道一直处于保活在线状态。其中，tSTB成功连接云端vSTB之后，t端代理模块内的代理执行单元Hub与v端代理模块内的代理执行单元Hub之间建立业务代理通道，且业务代理通道一直处于保活在线状态。
S202、tSTB的云化应用代理单元和vSTB的本地应用代理单元各自完成注册，实现两端应用列表的相互映射，确保应用列表信息同步一致。其中，应用列表包括本地应用列表以及云化应用列表。云化应用代理单元映射有云化应用列表，本地应用代理单元映射有本地应用列表。
S203至S204、当云端vSTB云化应用发送应用交互请求时，调用原有系统服务的接口，系统服务根据应用列表信息进行判断，当判断出应用交互请求的对象是本地应用，则绑定本地应用代理单元，通过业务代理通道，将应用交互请求传送给tSTB。
其中，应用交互请求可以包括以下至少之一：应用打开请求、应用关闭请求、应用安装请求、应用卸载请求、应用涉及的系统数据同步请求。然而，本申请对此并不限定。
其中，系统服务(system service)是指执行指定系统功能的程序、例程或进程，以便支持其他程序。
其中，系统服务可以根据应用交互请求携带的交互对象信息，查找云化应用列表，若未在云化应用列表查找到交互对象信息，则查找本地应用服务映射得到的本地应用列表，当在本地应用列表中查找到交互对象信息，则绑定本地应用代理单元，由本地应用代理单元通过调用业务代理通道传输应用交互请求给tSTB。当在云化应用列表查找到交互对象信息，则系统服务处理 应用交互请求。当没有在云化应用列表和本地应用列表中查找到交互对象信息，则结束处理。
S205、tSTB接收到由业务代理通道传来的应用交互请求后，通过云化应用代理单元对应用交互请求进行处理，并将处理结果回传至云端vSTB。
其中，tSTB的云化应用代理单元接收到由业务代理通道传来的应用交互请求后，调用系统服务处理该应用交互请求；在得到处理结果后，云化应用代理单元通过业务代理通道将处理结果回传给云端vSTB的本地应用代理单元。
本示例性实施例中，vSTB和tSTB之间通过本地应用代理单元、云化应用代理单元和业务代理通道实现应用交互，云化应用和本地应用无需因云化而修改原有交互方式及接口，可以实现无云感的正常交互体验，从而大大提升云化机顶盒系统的业务体验度。
图3为本申请实施例中用户使用云化机顶盒系统进行应用交互的场景流程图。如图3所示，在本实施例中，用户使用云化机顶盒系统的常用场景包括以下过程：
S301、用户打开电视和实体机顶盒，实体机顶盒自动连接云端vSTB；
S302、实体机顶盒通过电视展示云端vSTB的云化应用界面；
S303、用户使用遥控器点击云化应用页面设置入口，进入机顶盒设置页面；
S304、实体机顶盒开始展示本地应用设置页面；
S305、用户使用遥控器退出设置页面；
S306、实体机顶盒恢复云化应用的界面展示。
图4为本申请实施例提供的实现应用交互的示例性实施流程图。在本示例中，tSTB上运行有第一代理服务模块(包括云化应用代理单元和代理执行单元Hub)，vSTB上运行有第二代理服务模块(包括本地应用代理单元和代理执行单元Hub)。根据图3所述的用户使用场景，本实施例实现的vSTB和tSTB的应用交互的场景流程如图4所示，包括以下过程：
S401、tSTB通过认证请求成功连接到云端vSTB。
S402至S403、tSTB与云端vSTB之间建立业务代理通道；其中，在tSTB的代理执行单元Hub和云端vSTB的代理执行单元Hub之间建立业务代理通道；而且，在tSTB侧，云化应用代理单元完成代理自注册，映射有vSTB侧运行的云化应用列表；在vSTB侧，本地应用代理单元完成代理自注册，映射有tSTB侧运行的本地应用列表。
S404至S406、当tSTB正常连接到云端vSTB后，云端vSTB对来自云化应用的用户界面(UI)帧进行流化等处理，然后把流化的UI流传输给tSTB，tSTB解码处理后把EPG显示在电视(TV，Television)上。
S407至S411、当用户使用遥控器进行按键操作时，tSTB把遥控器的按键输入指令传递给云端vSTB(比如，tSTB通过桌面通道将按键输入指令传递给云端vSTB)，云端vSTB进行按键事件的处理。其中，当按键事件触发了应用交互请求时，云端vSTB调用系统服务接口，通过判断应用列表信息(包括本地应用列表和云化应用列表)，得知待交互的应用运行在tSTB而非云端vSTB，则进一步绑定本地应用代理单元，通过走业务代理通道，将应用交互请求传输至tSTB。
其中，应用交互请求中可以携带待交互的应用信息，通过从应用列表中查找匹配的应用信息，来判断待交互的应用运行在tSTB还是云端vSTB。
S412至S413、tSTB接收到业务代理通道传来的应用交互请求后，通过云化应用代理单元，进行处理，并将处理结果回传给云端vSTB。
其中，云化应用代理单元可以通过调用系统服务，来处理应用交互请求，并将执行结果通过业务代理通道回传给云端vSTB的本地应用代理单元。
同理，当本地应用界面显示在电视上时，用户使用遥控器进行按键操作；当按键事件触发了应用交互请求时，tSTB可以调用系统服务接口，通过判断应用列表信息，得知应用运行在云端vSTB而非tSTB，则进一步绑定云化应用代理单元，通过业务代理通道，将应用交互请求传输至云端vSTB；云端vSTB接收到业务代理通道传来的应用交互请求后，通过本地应用代理单元，进行处理；其中，本地应用代理单元可以通过调用系统服务，得到处理结果，并将执行结果通过业务代理通道回传给tSTB，实现应用交互。
在上述工作流程中，涉及云端vSTB和tSTB应用交互的两个处理过程，云端vSTB和tSTB应用交互基本保持原有方式，真正消除了云化带来的应用交互影响，实现无云化感，大大提升云化机顶盒系统的业务体验度。
图5为本申请实施例提供的实现视频播放的示例性实施流程图。在本示例中，tSTB上运行有第一代理服务模块(包括云化应用代理单元和代理执行单元Hub)，vSTB上运行有第二代理服务模块(包括本地应用代理单元和代理执行单元Hub)。在本实施例中，云化框架中，媒体播放统一在tSTB执行。如图5所示，基于云端vSTB和tSTB之间通过代理服务实现信息交互的方式，用户实现视频播放的实施流程包括：
S501、tSTB认证通过成功接入云平台后，自动连接上由云平台分配下来的云端vSTB。
S502至S503、tSTB与云端vSTB之间建立业务代理通道；其中，在tSTB的代理执行单元Hub和云端vSTB的代理执行单元Hub之间建立业务代理通道；而且，在tSTB侧，云化应用代理单元完成代理自注册，映射有云端vSTB侧运行的云化应用列表；在云端vSTB侧，本地应用代理单元完成代理自注册，映射有tSTB侧运行的本地应用列表。
S504至S506、tSTB正常连接到云端vSTB后，云端vSTB对来自EPG的UI帧进行流化等处理，然后把流化的UI流传输给tSTB，tSTB解码处理后把EPG显示在电视上。
S507至S511、当用户使用遥控器按下节目播放按钮，tSTB把遥控器的按键输入传递给云端vSTB，云端vSTB处理播控消息后，调用系统服务MediaCodec，系统服务MediaCodec通过绑定本地应用代理单元，调用业务代理通道，把视频的播控指令回传给tSTB。
S512至S515、tSTB获取播控指令后，向CDN发起播控请求，CDN响应播控请求，把音视频流传给tSTB进行播放；tSTB将音视频流传输给电视进行显示。
S516至S517、当用户使用遥控器按下退出播放按钮，tSTB结束视频播放，电视显示EPG UI。
经过上述实施流程，完成了云端vSTB和tSTB通过信息获取代理方式实现对EPG的视频播放。
需要说明的是，本申请实施例的业务场景并不局限于上述应用交互、EPG视频播放等，对于其他涉及大数据量的信息交互场景均可以使用本申请的方案。
