随着通信及互联网技术的高速发展，用户带宽不断升级，传统的物理机顶盒有限的中央处理器(central processing unit，简称为CPU)、随机存取存储器(Random Access Memory，简称为RAM)等性能以及日渐发展的虚拟现实技术(Virtual Reality，简称为VR)、游戏及各类定制化业务需求，各项业务云化成为趋势。虽然云化业务能够解决目前的物理机顶盒的性能问题，然而将所有业务均通过云化应用处理，会带来较大的云上资源消耗。
发明内容
本公开实施例的主要目的在于提出一种应用处理方法、系统、电子设备和计算机可读存储介质，使得可以降低云上资源消耗。
为至少实现上述目的，本公开实施例提供了一种应用处理方法，应用于虚拟机顶盒vSTB，所述vSTB中运行有云化应用，所述方法包括：接收对所述云化应用的交互操作指令；在确定所述交互操作指令用于指示播放音视频的情况下，根据所述交互操作指令确定需播放的音视频的统一资源定位符url；将所述url发送至瘦机顶盒tSTB，以使所述tSTB根据所述url获取并播放所述需播放的音视频。
为至少实现上述目的，本公开实施例还提供了一种应用处理方法，应用于瘦机顶盒tSTB，包括：向虚拟机顶盒vSTB发送对所述云化应用的交互操作指令，以使所述vSTB在确定所述交互操作指令用于指示播放音视频的情况下，根据所述交互操作指令确定需播放的音视频的统一资源定位符url；其中，所述vSTB中运行有所述云化应用；接收所述vSTB发送的所述url；根据所述url获取并播放所述需播放的音视频。
为至少实现上述目的，本公开实施例还提供了一种应用处理系统，包括：瘦机顶盒tSTB和虚拟机顶盒vSTB，所述vSTB中运行有云化应用；所述vSTB，用于接收对所述云化应用的交互操作指令；在确定所述交互操作指令用于指示播放音视频的情况下，根据所述交互操作指令确定需播放的音视频的统一资源定位符url；将所述url发送至瘦机顶盒tSTB；所述tSTB，用于接收所述url，并根据所述url获取并播放所述需播放的音视频。

本公开实施例提供的应用处理方法，考虑到如果播放音视频这种业务通过云化应用来进行解码传输，可能会带来较大的云上资源消耗，而对云化应用的交互操作指令往往占用户对云化应用的总使用时长中的极少部分，用户一旦点击进入应用场景，往往会进入一段无交互操作的真空期，一旦用户长时间未进行任何操作，基本可视为用户对云化应用已处于体验、暂停或闲暇状态。因此，本公开实施例在确定交互操作指令用于指示播放音视频的情况下，根据交互操作指令确定需播放的音视频的url；将url发送至瘦机顶盒tSTB，以使tSTB根据url获取并播放需播放的音视频。音视频播放这一业务占用带宽大，对性能要求适中，当前用户机顶盒的解码性能仍能满足交互式网络电视(Internet Protocol television，IPTV)的高清、超高清视频播放、点播等基本业务，因此本公开实施例中，虽然使用了云化应用，但相当于将云化应用中的音视频播放业务留给tSTB执行，有利于避免音视频播放业务会耗费较大的云上资源，从而可以在使用云化应用解决新业务部署带来的物理硬件不满足、机型适配复杂等问题的同时，降低云上资源消耗。

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合附图对本公开的各实施例进行详细的阐述。然而，本领域的普通技术人员可以理解，在本公开各实施例中，为了使读者更好地理解本公开而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施例的种种变化和修改，也可以实现本公开所要求保护的技术方案。以下各个实施例的划分是为了描述方便，不应对本公开的具体实现方式构成任何限定，各个实施例在不矛盾的前提下可以相互结合相互引用。
本公开的一个实施例提供了一种应用处理方法，应用于虚拟机顶盒(virtual Set-Top Box，简称为vSTB)，vSTB与瘦机顶盒(thin Set-Top Box，简称为tSTB)连接，vSTB位于主机中，vSTB中运行有云化应用；其中，云化应用比如可以为：人机交互(User Interface，简称 为UI)类应用、视听类应用、游戏类应用。在一些实施例中，主机中包括多个vSTB，每个vSTB中可以运行一个云化应用。其中，主机中包括多个vSTB也可以理解为主机中包括多个虚机。本实施例中的应用处理方法的流程图可以参考图1，包括：
步骤101：接收对云化应用的交互操作指令；
步骤102：在确定交互操作指令用于指示播放音视频的情况下，根据交互操作指令确定需播放的音视频的统一资源定位符url；
步骤103：将url发送至瘦机顶盒tSTB，以使tSTB根据url获取并播放需播放的音视频。
本公开实施例提供的应用处理方法，考虑到如果播放音视频这种业务通过云化应用来进行解码传输，可能会带来较大的云上资源消耗，而对云化应用的交互操作指令往往占用户对云化应用的总使用时长中的极少部分，用户一旦点击进入应用场景，往往会进入一段无交互操作的真空期，一旦用户长时间未进行任何操作，基本可视为用户对云化应用已处于体验、暂停或闲暇状态。因此，本公开实施例在确定交互操作指令用于指示播放音视频的情况下，根据交互操作指令确定需播放的音视频的url；将url发送至瘦机顶盒tSTB，以使tSTB根据url获取并播放需播放的音视频。音视频播放这一业务占用带宽大，对性能要求适中，当前用户机顶盒的解码性能仍能满足交互式网络电视(Internet Protocol television，简称为IPTV)的高清、超高清视频播放、点播等基本业务，因此本公开实施例中，虽然使用了云化应用，但相当于将云化应用中的音视频播放业务留给tSTB执行，有利于避免音视频播放业务会耗费较大的云上资源，从而可以在使用云化应用解决新业务部署带来的物理硬件不满足、机型适配复杂等问题的同时，降低云上资源消耗。
在步骤101中，vSTB可以接收tSTB发送的对云化应用的交互操作指令。
其中，交互操作指令比如可以为能够体现人机交互的操作，比如可以在云化应用的显示界面上的触摸操作、点击操作、滑动操作、输入操作等。
在步骤102中，vSTB在确定交互操作指令用于指示播放音视频的情况下，根据交互操作指令确定需播放的音视频的统一资源定位符(Uniform Resource Locator，简称为URL)。也就是说，在vSTB中运行的云化应用需要进行音视频播放时，云化应用可以确定需要播放的音视频的url。
比如，当用户在该视频播放应用的显示界面上点击了对“电影A”或“歌曲B”的播放按键，可以确定交互操作指令用于指示播放音视频，从而根据交互操作指令确定需播放的“电影A”或“歌曲B”的URL。
在步骤103中，vSTB可以将确定的url发送给tSTB，使得tSTB可以根据url获取需要播放的音视频，并进行解码播放。
在一个实施例中，在确定交互操作指令不用于指示播放音视频的情况下，vSTB可以执行交互操作指令，并将对交互操作指令的执行结果发送tSTB，以使tSTB展示执行结果。比如，假设云化应用为云化的视频播放应用，当用户在该视频播放应用的显示界面上的搜索框中输了“电影A”(输入操作)，并点击了搜索框旁边的确认搜索按钮(搜索操作)，则vSTB中运行的云化应用可以执行该输入操作和搜索操作，搜索到电影A，并将搜索到的电影A这一执行结果发送给tSTB，从而tSTB可以在电视机上展示该执行结果，比如展示和电影A相关的信息，比如，电影A的简介、播放量等信息。其中，输入操作和搜索操作即可以理解为不用于指示播放音视频交互操作指令。
在一个实施例中，假设云化应用为云化的视频播放应用，用户在云化的视频播放应用进行交互操作，比如输入操作、搜索操作等不用于指示播放音视频交互操作指令，一旦进入视频播放应用的播放视频业务场景即用户点击了对某视频的播放按键，进行了用于指示播放音视频的交互操作指令，vSTB可以获取用户点击的某视频的url，并下发url到tSTB，由tSTB根据该url获取视频源，即获取需要播放的视频资源，并进行解码播放。
在一个实施例中，假设云化应用为云化的音乐播放应用，用户在云化的音乐播放应用进行交互操作，比如通过输入操作搜索音乐，通过滑动操作浏览想听的音乐，一旦播放音乐的场景即用户点击了对某音乐的播放按键，vSTB可以下发用户选择播放的音乐的url到tSTB，由tSTB根据该url获取音频源，即获取需要播放的音频资源，并进行解码播放。
在一个实施例中，实现应用处理方法的架构示意图可以参考图2，基于图2中的架构实现业务分流，将应用进行云化，音视频播放保留在tSTB本地进行。图2中，L1、L2、L3分别表示3个vSTB中分别运行的云化后的UI类应用、视听类应用、游戏类应用。图2中，s1表示有线电视等传统视频业务直接由机顶盒进行承载。s2表示UI类、视听类、游戏类等应用的云化，vSTB中运行云化后的应用，对于游戏应用的云化处理，vSTB主要进行GPU渲染加速，使得用户可以和在云端运行的游戏应用进行交互。s3表示云化后的应用与tSTB之间的数据交互，该数据交互包括云化后的应用对交互操作指令的执行结果和音视频url。对于云化后的游戏应用，其与tSTB之间的数据交互包括游戏画面和用户的游戏的操作指令。
在一个实施例中，主机可以根据多个vSTB即虚机承载的业务场景及业务量，按照CPU、内存等维度对每个vSTB分配对应的资源，使得每个vSTB可以被合理的分配资源。
本公开中考虑到如果播放音视频这种业务通过云化应用来进行解码传输，可能会带来较大的云上资源消耗，而对云化应用的交互操作指令往往占用户对云化应用的总使用时长中的极少部分，用户一旦点击进入应用场景，往往会进入一段无交互操作的真空期，一旦用户长时间未进行任何操作，基本可视为用户对云化应用已处于体验、暂停或闲暇状态。因此，本公开实施例通过分流，在需要对vSTB中运行的云化应用执行交互操作指令的情况下，通过云化应用执行交互操作指令，并接收对交互操作指令的执行结果；在需要基于云化应用进行音视频播放的情况下，接收云化应用发送的需要播放的音视频的url，根据url获取并播放需要播放的音视频。即，本公开实施例中将云化应用的业务分流为交互操作指令和音视频播放，音视频播放这一业务占用带宽大，对性能要求适中，当前用户机顶盒的解码性能仍能满足IPTV的高清、超高清视频播放、点播等基本业务，因此本公开实施例中，虽然使用了云化应用，但相当于将云化应用中的音视频播放业务留给tSTB执行，将云化应用中的仅需要消耗较少云上资源的交互操作指令留给云化应用执行，有利于避免音视频播放业务会耗费较大的云上资源，从而可以在使用云化应用解决新业务部署带来的物理硬件不满足、机型适配复杂等问题的同时，降低云上资源消耗。
在一个实施例中，vSTB位于主机中，主机中包括多个vSTB，vSTB的状态包括挂起状态和正常状态，在处于正常状态的vSTB中存在满足预设的虚机挂起条件的vSTB的情况下，满足虚机挂起条件的vSTB的状态被切换为挂起状态；在处于挂起状态的vSTB中存在满足预设的虚机恢复条件的vSTB的情况下，满足虚机恢复条件的vSTB的状态被切换为正常状态。
在一个实施例中，预设的虚机挂起条件包括：在第一预设时间段内对vSTB无任何操作； 或，vSTB处于降低帧率状态且在第二预设时间段内对所述vSTB无任何操作；其中，降低帧率状态为tSTB与vSTB初次连接后，在第三预设时间段内对vSTB无任何操作的情况下，vSTB进入的状态。
在一个实施例中，预设的虚机恢复条件包括以下之一或其任意组合：接收到交互操作指令、电子节目指南EPG中视频播放完成或失败、云化应用中视频播放完成或失败。
在一个实施例中，在处于挂起状态的vSTB处于挂起状态的持续时长超过第四预设时长的情况下，每隔第四预设时长，处于挂起状态的vSTB的状态被切换为正常状态，并在第五预设时长内未检测到对切换为正常状态的vSTB的操作的情况下，切换为正常状态的vSTB被再次挂起；其中，第四预设时长大于五预设时长。
本公开的一个实施例提供了一种应用处理方法，应用于tSTB，该应用处理方法的流程图可以参考图4，包括：
步骤401：向vSTB发送对云化应用的交互操作指令，以使vSTB在确定交互操作指令用于指示播放音视频的情况下，根据交互操作指令确定需播放的音视频的url；其中，vSTB中运行有云化应用；
步骤402：接收vSTB发送的url；
步骤403：根据url获取并播放需播放的音视频。
不难发现，本实施方式为与上述应用于vSTB的应用处理方法的实施例相对应的应用于主机的应用处理方法的实施例。本实施方式可与上述应用于vSTB的应用处理方法的实施例互相配合实施。上述应用于vSTB的应用处理方法的实施例中提到的相关技术细节和技术效果在本实施方式中依然有效，为了减少重复，这里不再赘述。相应地，本实施方式中提到的相关技术细节也可应用在上述应用于vSTB的应用处理方法的实施例中。
在一个实施例中，主机中包括多个vSTB，vSTB的状态包括挂起状态和正常状态，应用处理方法除了图4中的步骤401至步骤403之外，还包括：在处于正常状态的vSTB中存在满足预设的虚机挂起条件的vSTB的情况下，将满足虚机挂起条件的vSTB的状态切换为挂起状态；在处于挂起状态的vSTB中存在满足预设的虚机恢复条件的vSTB的情况下，将满足虚机恢复条件的vSTB的状态切换为正常状态。其中，主机中包括多个vSTB，也可以理解为主机中包括多个虚机。满足预设的虚机挂起条件的vSTB可以理解为不活跃的虚机，本公开实施例通过及时挂起不活跃的虚机，能够有效地最大化利用云化主机的性能，从而提高虚机的并发数量。通过将满足虚机恢复条件的vSTB的状态切换为正常状态，使得可以不影响需要工作的虚机正常工作。
上述的虚机挂起条件和虚机恢复条件可以根据实际需要进行设置，虚机挂起条件用于表征虚机不活跃，即使挂起也不会对用户需要的业务造成较大影响。虚机恢复条件用于表征虚机从不活跃开始活跃，如果不将虚机的状态从挂起状态切换为正常状态，可能会对用户的业务造成影响。
在一个实施例中，上述的虚机挂起条件包括：在第一预设时间段内对vSTB无任何操作；其中，第一预设时间段可以根据实际需要进行设置，比如可以设置为5分钟，即如果在5分 钟内未检测到对vSTB的任何操作，可以将该vSTB挂起。其中，在5分钟内未检测到对vSTB的任何操作，也可以理解为在5分钟内未检测到对vSTB中运行的云化应用的任何操作。也就是说，如果用户长时间未操作vSTB，则将vSTB挂起，考虑到用户长时间未操作vSTB，接下来继续操作vSTB的可能性较小，表明该vSTB不活跃，此时将vSTB挂起不会对用户需要的业务造成较大影响。
在一个实施例中，上述虚机挂起条件包括：vSTB处于降低帧率状态且在第二预设时间段内对vSTB无任何操作；其中，降低帧率状态为tSTB与vSTB初次连接后，在第三预设时间段内对vSTB无任何操作的情况下，vSTB进入的状态。第二预设时间段和第三预设时间段可以根据实际需要进行设置为相同或不同，比如可以均设置为5分钟，即tSTB与vSTB初次连接后，如果5分钟内对vSTB无任何操作，不会触发虚机挂起，而是降低vSTB的帧率，使vSTB进入降低帧率状态。在vSTB降低帧率5分钟后，并且对该vSTB仍无任何操作，则将该vSTB挂起，即将该vSTB的状态切换为挂起状态。先降低vSTB的帧率，使得可以降低CPU的负荷，在减少资源消耗的同时为vSTB争取较长的非挂起时间，避免vSTB较快的被挂起。
在一个实施例中，上述的虚机恢复条件包括以下之一或其任意组合：接收到交互操作指令、电子节目指南(Electronic Program Guide，EPG)中视频播放完成或失败、云化应用中视频播放完成或失败。其中，接收到交互操作指令、EPG中视频播放完成或失败、云化应用中视频播放完成或失败均表明接下来可能需要响应用户的一些操作指令，比如：接收到交互操作指令，云化应用需要执行该交互操作指令；如果EPG或云化应用中视频播放完成或失败，用户可能需要操作以实现重新播放视频或是退出播放视频，以改变视频播放完成或失败这一状态。其中，接收到交互操作指令可以理解为用户发送按键、遥杆、触摸信息等。在本实施例提供的虚机恢复条件下，将vSTB的状态恢复为正常状态，有利于满足用户后续可能需要的业务需求。
在一个实施例中，主机中的多个虚机的状态切换也可以由主机统一进行管理控制，主机可以实时获取多个虚机的状态，并根据多个虚机的状态进行正常状态和挂起状态之间的切换。
在一个实施例中，在处于所挂起状态的vSTB处于挂起状态的持续时长超过第四预设时长的情况下，每隔所述第四预设时长将处于挂起状态的vSTB的状态切换为正常状态，并在第五预设时长内未检测到对切换为正常状态的vSTB的任何操作的情况下，将切换为正常状态的vSTB再次挂起；其中，第四预设时长大于五预设时长。第四预设时长和五预设时长可以根据实际需要进行设置，第四预设时长可以设置为小时级别，第五预设时长可以设置为分钟级别。比如，第四预设时长可以设置为4小时，第五预设时长可以设置为1分钟，即tSTB可以每隔4小时将持续处于挂起状态的vSTB恢复一次，如果在恢复为正常状态的1分钟内，仍未检测到对vSTB的任何操作，则tSTB可以将该vSTB再次挂起。每隔第四预设时长将vSTB恢复一次，有利于保证vSTB恢复的时效性。
在一个实施例中，上述的处于正常状态的vSTB的EPG心跳链路由vSTB和EPG服务器 保持；上述的处于挂起状态的vSTB的EPG心跳链路由tSTB和EPG服务器保持。也就是说，当vSTB处于正常状态时，由vSTB向EPG服务器发送保活心跳，以维持vSTB和EPG服务器之间的心跳链路。当vSTB处于挂起状态时，由tSTB代理vSTB向EPG服务器发送保活心跳，以维持vSTB和EPG服务器之间的心跳链路。因此，本公开实施例可以在vSTB处于不同状态时均能够正常维持vSTB和EPG服务器之间的心跳链路，有利于保证需要使用EPG服务器时的时效性。
在一个实施例中，在将满足虚机挂起条件的vSTB的状态切换为挂起状态之前，还包括：向vSTB请求vSTB登录的EPG服务器的信息；在将满足虚机挂起条件的vSTB的状态切换为挂起状态之后，还包括：根据请求的EPG服务器的信息，确定需要与处于挂起状态的vSTB保持心跳的EPG服务器；tSTB代理处于挂起状态的vSTB向确定的EPG服务器发送保活信号，以使处于挂起状态的vSTB的EPG心跳链路由tSTB和确定的EPG服务器保持。其中，EPG服务器的信息可以包括EPG服务器域名(简称EPGdomain)、EPG服务端口号(简称EPGport)。也就是说，vSTB虚机挂起前，tSTB先向vSTB请求vSTB登录的EPGdomain和EPGport，使得tSTB可以根据请求得到的EPGdomain和EPGport确定需要与处于挂起状态的vSTB保持心跳的EPG服务器，从而使得后续即使vSTB虚机挂起，tSTB也可以代理该vSTB虚机成功向EPG服务器发送保活心跳。
在一个实施例中，应用处理方法的交互示意图可以参考图3，包括：
步骤301：建立连接；
比如，tSTB接入云化机顶盒服务确定需要连接的vSTB，从而tSTB与需要连接的vSTB建立连接通道。
步骤302：传递业务平台账户和密码，触发登录；
比如，tSTB通过向vSTB传递业务平台账户和密码，使得vSTB完成业务平台登录认证，并获取登录的EPGdomain和EPGport。
步骤303：判断是否需要降低vSTB的帧率，或是将vSTB挂起；
比如，在vSTB虚机处于正常状态时，启动定时器计时。根据包括但不限于下列规则判断是否需要降低vSTB的帧率或是挂起虚机：
用户初次连接进入云端时(即tSTB与vSTB初级建立连接或是刚建立连接)，对vSTB无任何操作一定时长内(比如5分钟)，不会触发vSTB虚机挂起，控制vSTB虚机进入降低帧率状态。其中，虚机挂起即可以理解为将虚机的状态切换为挂起状态。需要说明的是，上述的5分钟只是示例性的说明，在具体实现中并不以此为限。
vSTB虚机降低帧率5分钟后，并且对vSTB虚机仍无任何操作，判定可以将vSTB虚机挂起；其中，对vSTB虚机仍无任何操作可以理解为用户对vSTB虚机中运行的云化应用没有任何操作。
当检测到用户有操作行为且vSTB虚机处于降低帧率(简称降帧)状态，则解除降帧，恢复正常帧率。
步骤304：如果判定判断vSTB虚机需要挂起，tSTB向vSTB请求EPGdomain和EPGport；
步骤305：vSTB向tSTB发送EPGdomain和EPGport；比如，tSTB得到EPGdomain和 EPGport后，可以根据EPGdomain和EPGport确定与vSTB保持心跳连接的EPG服务器的地址，从而可以在vSTB挂起后，代理vSTB向EPG服务器发送保活心跳。
步骤306：tSTB触发vSTB虚机挂起；其中，挂起成功后，记录vSTB虚机状态为挂起，并停止计时器。
步骤307：tSTB代理vSTB虚机与EPG服务器保持心跳链路；
即，vSTB虚机挂起后，有EPG的vSTB虚机由tSTB代理定时向登录的EPG服务器发送保活心跳，以保持心跳链路。
步骤308：tSTB定时恢复vSTB虚机，1分钟后再次挂起；
即，如果vSTB虚机长时间挂起，为保证vSTB虚机恢复的时效性，tSTB可以每隔一定时长(比如4小时)将vSTB虚机恢复一次，恢复正常后，如果1分钟内还是没有检测到对vSTB虚机的任何操作，则将vSTB虚机再次挂起。需要说明的是，本实施例提到的1分钟、4小时只是示例性的说明，在具体实现中，并不以此为限。
步骤309：判断是否需要将挂起的vSTB虚机恢复；
本实施例中，vSTB虚机在挂起状态下：包括但不限于以下情形会触发vSTB虚机恢复：用户发送按键、遥杆、触摸信息等即检测到用户的交互操作指令；EPG中视频播放完成或失败；APK中视频播放完成或失败。
步骤310：tSTB向vSTB虚机发送指令，以恢复vSTB虚机；
也就是说，当判定需要将挂起的vSTB虚机恢复，tSTB向vSTB虚机发送恢复指令，vSTB虚机恢复成功后，记录vSTB虚机的状态为正常状态，vSTB虚机恢复即可以理解为将vSTB虚机的状态切换为正常状态。
步骤311：vSTB虚机恢复后，vSTB虚机与EPG服务器保持心跳；
也就是说，vSTB虚机恢复后，有EPG的虚机的EPG心跳链路也恢复为由vSTB和EPG服务器间保持。
本实施例中，考虑到单台主机能够正常运行的vSTB虚机数量有限，大量增设主机势必导致成本不断增加，而成本问题是当前制约云化机顶盒技术落地的重要影响因素。基于此，本实施例相当于提供了一种适用于云化机顶盒提升单台主机中虚机并发数的方法，能够在一定程度上解决云化机顶盒技术与成本之间的矛盾，通过合理检测用户行为，及时挂起不活跃的vSTB虚机，能够有效地最大化利用云化主机的性能，从而提高vSTB虚机的并发数量。同时，通过实现分流，vSTB虚机提供应用虚拟化业务场景，机顶盒实现解码播放音视频，还能有效的降低云上资源消耗，使得云上有限的资源能够满足更多vSTB虚机的需求，有利于进一步提高vSTB虚机的并发数量。本实施例实现了在云化应用的场景下音视频播放码流的切换和活跃虚机资源的动态管理，在保证用户体验正常的同时，提高了单台主机并发运行虚机的数量，降低了运营成本。
需要说明的是，本公开实施例中的上述各示例均为为方便理解进行的举例说明，并不对本发明的技术方案构成限定。
