Description

基于CDN的视频推送方法、系统、及设备
本申请要求在2015年12月15日提交中国专利局、申请号为201510953132.0、发明名称为“基于CDN的视频推送方法、系统、及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及视频点播技术领域，更具体地，本发明涉及一种基于CDN的视频推送方法、能够实现该视频推送方法的视频推送系统、及设置有该种视频推送系统的设备。
背景技术
目前内容分发网络(Content Delivery Network，CDN)已经广泛用于视频服务器搭建，搭建的CDN节点越多，CDN覆盖的用户就越多，用户与CDN节点的空间距离也就越近。如果用户点播的视频内容能够在空间距离最近的CDN节点上获取到，便能获得最快的播放速度。由于CDN节点具有存储空间的限制，其不可能对所有视频内容进行缓存，因此，CDN的分发控制中心会将点播较多的热点视频分发至所有CDN节点进行缓存，以保证热点视频的播放体验，并将点播较少的冷点视频分发至少数的CDN节点进行缓存，以合理地利用资源避免过载。
但发明人在实现发明的过程中发现，基于该种分发方案，如果用户点播了冷点视频，则需要从缓存有该冷点视频的CDN节点获取并中转到空间距离最近的CDN节点进行播放，但在大部分情况下，用户随意点播的冷点视频很可能仅播放几分钟就因不感兴趣而被关闭，这就增加了CDN的调度压力，而且还影响播放体验。

本发明实施例的第三个目的是提供一种设备，以使用户在经由该设备进行视频点播时，能够缓解CDN调度压力。
根据本发明实施例的第三方面，提供了一种设备，其具有视频播放系统和上述视频推送系统。
本发明的发明人发现，在现有技术中，存在CDN调度压力大的问题。因此，本发明所要实现的技术任务或者所要解决的技术问题是本领域技术人员从未想到的或者没有预期到的，故本发明实施例提供的是一种新的技术方案。
本发明的一个有益效果在于，本发明实施例提供的基于CDN的视频推送方法、系统及设备可通过将最近几个CDN节点缓存的视频内容列表作为热点 视频内容列表推送给用户，这样就增加了用户通过热点视频内容列表随意点播感兴趣的视频内容的几率，进而降低了用户随意点播由较远CDN节点缓存的冷点视频的几率，而由于热点视频内容列表中的视频内容均能够通过较近的CDN节点获取，因此将明显缓解CDN的调度压力。
通过以下参照附图对本发明的示例性实施例的详细描述，本发明的其它特征及其优点将会变得清楚。
附图说明
被结合在说明书中并构成说明书的一部分的附图示出了本发明的实施例，并且连同其说明一起用于解释本发明的原理。
图1所示为本发明实施例中的基于CDN的视频推送方法的一种实施方式的流程图；
图2所示为本发明实施例中的视频推送系统的一种实施结构的方框原理图。
具体实施方式
现在将参照附图来详细描述本发明的各种示例性实施例。应注意到：除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本发明的范围。
以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本发明及其应用或使用的任何限制。
对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为说明书的一部分。
在这里示出和讨论的所有例子中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它例子可以具有不同的值。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
为了解决因用户随意点播冷点视频、且观看时间通常很少，进而导致CDN调度压力较大的问题，本发明实施例提供了一种基于CDN的视频推送方法，如图1所示，该方法包括如下步骤：
步骤S1：搜索空间距离最近的当前设定数量的CDN节点作为目标节点。
该动作例如可以通过用户登录对应的客户端应用、刷新对应的客户端应用、查看热点视频内容列表、预先设定搜索周期等方式触发，每次触发将进行热点视频内容列表的更新。
该当前设定数量可以预先设定、可以支持用户根据需要更改、该还可以支持自动调整。
步骤S2：向每一目标节点发送获取列表请求，以使目标节点在接收到该获取列表请求后，返回已缓存的视频内容的视频内容列表。
对应地，目标节点可以对已缓存的视频内容进行统计并形成对应的视频内容列表，并根据分发控制中心的分发和删减实时更新该视频内容列表，以在接收到获取列表请求时能够快速地进行响应，进而加快以下的热点视频内容列表的获取速度。
步骤S3：在接收到目标节点返回的视频内容列表后，对接收到的视频内容列表进行整合得到热点视频内容列表。
该步骤S3可进一步限定为：在接收到所有目标节点返回的视频内容列表后，再对接收到的所有视频内容列表进行整合得到热点视频内容列表。这说明等待接收的最长时间将至下一次更新为止。
但为了避免出现因与部分目标节点通信故障而影响热点视频内容列表更新的问题，该步骤S3还可进一步限定为：在从发送获取列表请求起的设定时间内接收到目标节点返回的视频内容列表时，对该设定时间内接收到的视频内容列表进行整合得到热点视频内容列表。这说明，热点视频内容列表更新的最长等待时间为该设定时间，热点视频内容列表的每次更新将根据从发送获取列表请求起的设定时间内接收到的视频内容列表进行，设定时间内未接收到的视频内容列表将被忽略。如果在设定时间内接收到了所有目标节点返回的视频内容列表，则在接收到所有目标节点返回的视频内容列表后立刻进行整合得到热点视频内容列表，而不再等待设定时间的耗尽。
步骤S4：显示该热点视频内容列表，以供用户点播。
该步骤中具体的显示需要通过用户终端执行。
由此可见，本发明实施例提供的基于CDN的视频推送方法可将最近几个CDN节点缓存的视频内容列表作为热点视频内容推送给用户，这样就增加了用户通过热点视频内容列表随意点播感兴趣的视频内容的几率，进而降低了用户随意点播由较远CDN节点缓存的冷点视频的几率，由于热点视频内容列 表中的视频内容均能够通过空间距离最近的一个或者几个CDN节点获取，因此本发明实施例所述方法将能够明显缓解CDN的调度压力。
为了方便用户浏览热点视频内容列表，以提高用户体验，在本发明实施例的一个具体可实现方式中，上述步骤S4中显示所述热点视频内容列表可进一步包括如下步骤：
步骤A：根据视频内容的类型标识符拆分热点视频内容列表，得到与分类标签一一对应的分类视频内容列表。
对应地，目标节点返回的视频内容列表中，应该具有反映各视频内容类型的类型标识符，该类型例如包括电影、电视剧、综艺、动漫、体育、音乐、纪录片等，而电视剧和电影下还可细分为喜剧、爱情、悬疑、欧美、内地、港台、日韩等类型分类，因此，同一视频内容可能属于多个分类标签。
该步骤A中根据视频内容的类型标识符拆分所述热点视频内容列表可进一步包括如下步骤：
步骤A1：获取分类显示中设定的分类标签；
形成与分类标签一一对应的分类视频内容列表；
根据视频内容的类型标识符，将所述热点视频内容列表中的视频内容分类添加至对应的分类视频内容列表中。
步骤A2：在各分类标签下显示对应的分类视频内容列表。
为了使本发明实施例所提供的方法能够支持根据实际需要更改上述当前设定数量的应用，在本发明实施例的一个具体可实现方式中，该方法还可以包括：在接收到用户输入的设定数量后，将当前设定数量更新为用户输入的设定数量；该方法还可以包括：以设定的时间周期计算用户在上一时间周期内通过热点视频内容列表点播视频内容的次数；如果次数小于设定次数，且当前设定数量小于设定数量上限，则按照设定调节步距增大该当前设定数量。该调节步距可以设定为1，而且该当前设定数量的初始值优选是设置为1，以提高热点视频内容列表更新的速度，进而获得最佳的用户体验。
在上述视频推送方法的基础上，本发明实施例还提供了一种能够实现本发明实施例所提供的方法的基于CDN的视频推送系统，如图2所示，该视频推送系统包括搜索模块1、请求模块2、列表处理模块3和显示处理模块4，其中，该搜索模块1用于搜索空间距离最近的当前设定数量的CDN节点作为目标节点；该请求模块2用于向每一所述目标节点发送获取列表请求，以使 所述目标节点在接收到所述获取列表请求后，返回已缓存的视频内容的视频内容列表；该列表处理模块3用于接收目标节点返回的视频内容列表，并对接收到的视频内容列表进行整合得到热点视频内容列表；该显示处理模块4用于显示热点视频内容列表，以供用户点播。
上述列表处理模块3还可以进一步用于在从发送获取列表请求起的设定时间内接收到所述目标节点返回的视频内容列表时，对设定时间内接收到的视频内容列表进行整合得到热点视频内容列表。
上述显示处理模块4还可以具体用于根据视频内容的类型标识符拆分所述热点视频内容列表，得到与分类标签一一对应的分类视频内容列表，并在各分类标签下显示对应的分类视频内容列表。
上述显示处理模块4还可以具体用于获取分类显示中设定的分类标签，形成与分类标签一一对应的分类视频内容列表，并根据视频内容的类型标识符，将所述热点视频内容列表中的视频内容分类添加至对应的分类视频内容列表中。
本发明实施例所提供的系统还可以包括数量更新模块(图中未示出)，该数量更新模块用于接收用户输入的设定数量，并将所述当前设定数量更新为所述用户输入的设定数量；及/或，用于以设定的时间周期计算用户在上一时间周期内通过所述热点视频内容列表点播视频内容的次数，如果所述次数小于设定次数，且所述当前设定数量小于设定数量上限，则按照设定调节步距增大所述当前设定数量。
本发明实施例还提供了一种设备，该设备具有本发明实施例提供的的视频推送系统，因此本发明实施例提供的所述设备能够在用户进行视频点播时，缓解CDN调度压力。该设备可以是具有视频播放功能的任意设备，例如是手机、电视、平板电脑等用户终端。
