背景技术
用户可以在线搜索各视频供应商提供的视频数据，但考虑到用户等级或者用户人群的不同，有些视频数据只能给会员用户观看，有些视频数据中可能包括限制级片段，例如不适宜儿童或者青少年观看的暴力情节片段或者成人思想片段。视频供应商需要对这些用户进行分门别类的提供视频数据，主要采用下述三种方式：(1)对限制级片段进行裁剪，然后分门别类的保存多个不同视频源的视频数据来为不同的用户提供合适的视频数据；(2)对限制级片段打马赛克；(3)保存多份视频数据，即同时保存原始的视频数据、裁剪掉限制级片段的多份视频数据。
但是将所有限制性内容进行裁剪和打马赛克，有观看需求的用户就看不到限制级片段，这样无法满足不同类别用户的观看需求。而通过保存多份视频数据(包括已裁剪的和未裁剪的)的方式，又无法做到一份视频数据支持不同类别用户的观看，并且，针对不同的用户分发不同的视频数据，也给服务器带来额外的存储压力。

本申请供了一种媒体播放方法、服务器及终端设备，可用于直播技术领域。以下进行详细说明。图1为流媒体传输的一种网络拓扑图，服务器端存储各种视频片源，每种视频片源包括多个不同码率的分片，服务器可用于创建客户端、配置客户端的各种信息以及处理终端设备上针对客户端的各种请求，此外，还可用于保存使用客户端的用户的操作数据。终端设备上安装了交客户端，可响应于用户针对客户端的各种操作指令，能够与服务器进行交互。
本申请中，终端设备可向服务器发送播放请求以请求不同码率的分片，然后在终端设备上安装的客户端上播放。
其中，需要特别说明的是，本申请涉及的终端设备，可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。终端设备可以经无线接入网(英文全称：Radio Access Network，英文简称：RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语音和/或数据。例如，个人通信业务(英文全称：Personal Communication Service，英文简称：PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(Wireless Local Loop，英文简称：WLL)站、个人数字助理(英文全称：Personal Digital Assistant，英文简称：PDA)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程 站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、终端设备、用户代理(User Agent)、用户设备(User Device)、或用户装备(User Equipment)。
为解决上述技术问题，本申请主要提供以下技术方案：
服务器首先判断终端设备请求的媒体分片中是否包含限制级分片，若包含限制级分片，则判断该终端设备是否具备播放该限制级分片的权限，若不具备权限，则可将该媒体分片的分片索引文件中的限制级分片的分片索引信息删除或者隐藏，然后再把处理后的分片索引文件发给终端设备，这样就使得终端设备只能下载出限制级分片之外的分片了；而对于具备播放权限的终端设备，则可将包含该限制级分片的分片索引文件发给终端设备，那么该终端设备即可下载包含该限制级分片的媒体分片了；若该媒体分片中不包含限制级分片，则直接将媒体分片的分片索引文件发给终端设备，使得终端设备可直接下载完整的媒体分片。
请参照图2，以下对本申请提供一种媒体播放方法进行举例说明，所述方法包括：
201、终端设备向服务器发送播放请求。
其中，所述播放请求用于请求播放媒体分片。
202、服务器接收终端设备发送的播放请求。
203、服务器根据所述播放请求查询所述媒体分片的分片索引文件，根据所述媒体分片的分片索引文件确定出目标分片集合。
其中，所述目标分片集合是指所述媒体分片中所述终端设备具备播放权限的分片。
204、服务器确定与所述目标分片集合对应的目标分片索引文件。
在一些实施方式中，确定目标分片索引文件可采用下述方式：
(1)根据媒体分片当前的分片索引文件得到。
例如，可在媒体分片当前的分片索引文件的基础上编辑(例如隐藏或删除限制级分片的分片索引信息)得到。
(2)根据目标分片集合动态生成。
(3)直接从存储中获取预先存储的分片索引文件。
具体来说，可预先至少设置下述两种映射关系：
a、分片等级、对象等级和分片索引三者之间的映射关系。
b、分片等级、对象年龄和分片索引三者之间的映射关系。
c、分片等级、对象等级、对象年龄和分片索引四者之间的映射关系。
上述三种映射关系可以以列表的形式存储，也可以以其他的形式存储，具体呈现方式本申请不作限定。需要说明的是，本申请仅针对映射关系进行了上述举例，在其他实施方式中，还可以在各个映射关系中添加其他用于区分分片或者终端设备的参数，或者还可以减少上述三种映射关系中的某些参数，具体本申请不作限定。
服务器了根据预设的映射关系和所述媒体分片当前的分片索引文件，确定出所述目标分片索引文件，由此可见，通过该种方式去确定上述目标分片索引文件，能够加快响应终端设备的速度，通过预先将各种情况对应的分片索引文件都考虑到，一定程度上能优化媒体分片的管理机制。
205、服务器将所述目标分片索引文件发送给所述终端设备。
206、终端设备接收所述服务器发送的目标分片索引文件。
207、终端设备根据目标分片索引文件从所述服务器下载所述目标分片集合。
与现有机制相比，本申请提供的方案中，服务器接收终端设备发送的播放请求，然后根据播放请求查询媒体分片的分片索引文件，再确定一个表示所述媒体分片中所述终端设备具备播放权限的分片目标分片集合，再将所述目标分片集合对应的分片索引文件发送给所述终端设备，使得所述终端设备下载所述目标分片索引文件中各分片索引所对应的分片。这样就不需要分别针对不同级别的终端设备配置不同的分片了，只需要动态的改变发给终端设备的分片索引文件即可，仅需要基于同一份媒体分片就能实现为不同终端设备播放权限的终端设备提供合适的媒体分片，有效的区分不同的终端设备。
可选的，在一些发明实施例中，所述确定目标分片集合，以及确定与所述目标分片集合对应的目标分片索引文件，可包括下述三种情况：
一、当确定所述播放请求所请求播放的媒体分片中包含限制级分片时，若确定所述终端设备具备播放所述限制级分片的权限，则服务器可将所述媒体分片中的大众级分片和所述限制级分片作为所述目标分片集合。
然后，服务器可根据所述大众级分片的分片索引以及所述限制级分片的分片索引，生成所述目标分片索引文件；或者对当前媒体分片的分片索引文件进行修改，以得到上述目标分片索引文件，例如可删除其中的限制级分片的分片索引；或者，还可以通过隐藏其中的限制级分片的分片索引。
在情况一中，当限制级分片的个数为至少一个时，服务器确定所述终端设备具备播放所述限制级分片的权限的过程可以是：
若所述终端设备已登录账号，那么服务器可在获取该账号下的各种账号信息，该帐号信息可包括账号对应的虚拟对象的对象名称、对象等级、年龄、国籍或者住址等信息。然后，服务器可根据限制级分片的分片等级和所述账号对应的虚拟对象的对象等级，确定所述限制级分片中是否存在分片等级低于或等于所述对象等级的至少一个分片，若存在，则确定所述终端设备具备播放所述至少一个分片的权限。
二、当确定所述媒体分片中仅包含大众级分片时，则服务器可将所述媒体分片中所有的分片作为所述目标分片集合，也就是说所述目标分片集合可包括所述媒体分片中所有的分片。
然后，服务器可根据所述媒体分片中所有的分片的分片索引，生成所述目标分片索引文件，即所述目标分片索引文件包括所述媒体分片中所有的分片的分片索引。
三、当确定所述播放请求所请求播放的媒体分片中包含限制级分片时，若确定所述终端设备无播放所述限制级分片的权限，则服务器可将所述媒体分片中除所述限制级分片之外的分片作为所述目标分片集合，也就是说，所述目标分片集合可包括所述媒体分片中除所述限制级分片之外的分片。
然后，服务器根据所述媒体分片中除所述限制级分片之外的分片的分片索引，生成所述目标分片索引文件，即所述目标分片索引文件包括所述媒体分片中除所述限制级分片之外的分片的分片索引。
在情况三中，服务器确定所述终端设备无播放所述限制级分片的权限的情况可包括以下之一：
(a)若所述终端设备未登录账号，则服务器可向所述终端设备发送登录提示，若所述终端设备在预设时长内未登录账号，则可确定所述终端设备当前无播放所述限制级分片的权限。
例如，游客用户请求观看包含限制级分片的媒体分片时，服务器会在播放界面提示用户登录账号，若在2分钟内该用户依然未登录有效账号，那么可认为该用户无播放该媒体分片中的任意限制级分片的权限，那么，只需要为该用户提供过滤了限制级分片的媒体分片。
(b)若所述终端设备已登录账号，且服务器根据限制级分片的分片等级和所述账号对应的虚拟对象的对象等级，确定所述限制级分片中不存在分片 等级低于或等于所述对象等级的至少一个分片时，则服务器可确定所述终端设备无播放所述至少一个分片的权限。
例如，已登录账号的用户请求观看包含限制级分片的媒体分片时，服务器会获取该用户所登录账号的等级。若该账户的等级为高级会员，那么，可以认为该用户具备播放该媒体分片中所有限制级分片的权限；若该账户的等级为普通会员，那么，可以认为该用户仅具备播放该媒体分片中低于或等于普通会员级别内的限制级分片的权限，而不具有播放仅有高级会员才可观看的限制级分片；若该账户的等级为非会员，那么，可以认为该用户仅具备播放该媒体分片中大众级分片，而不具备播放普通会员或者高级会员才能观看的限制级分片的权限。
(c)若确定所述终端设备已登录账号，则根据登录的帐号对应的账号信息确定所述虚拟对象的对象年龄低于预设年龄，则确定所述终端设备不具备播放所述限制级分片的权限。
例如，已登录账号的用户请求观看包含限制级分片的媒体分片时，服务器会获取该用户所登录账号的帐号信息，例如账号等级、用户年龄或者性别等。若该用户的年龄小于12岁，那么，无论该用户的账号等级是否为普通会员还是高级会员或者为非会员，服务器都可认为该用户不具备播放分片索引文件中限定了12岁以下不能观看的所有限制级分片。
根据上述(a)、(b)和(c)三种情况，可以有效的区分出当前请求媒体分片的终端设备的播放媒体分片中各个分片等级的分片的权限，这样就可以基于一份媒体分片，就能为这些不同的终端设备提供相应的下载服务了。
可选的，在一些发明实施例中，服务器在向终端设备提供目标索引文件之前，还需要为各种媒体分片中所包括的分片进行设置，尤其是某些包含限制级分片的媒体分片。具体来说，服务器在获取待设置的视频数据后，可先提取视频数据中的关键帧，然后根据提取的关键帧对所述视频数据进行等级分析。然后根据分析的结果为所述视频数据中的各个视频片段分别进行等级标识，例如标识大众级、限制级等，这些等级标识能够定义是否能够播放该视频片段的播放限制条件。
然后，服务器将这些视频片段进行转码，转码完成后，再按照视频片段的等级将所述视频数据进行切片，切片后可得到包括至少两个分片的所述媒体分片，分片的分片等级与视频片段的等级对应，也就是说，每个分片都有一个分片等级，各个分片的等级可相同或不同。
在为每个分片设置完分片等级后，服务器可将所述媒体分片中各分片的分片等级写入初始分片索引文件。这样，后续服务器响应终端设备的播放请求时，可动态的基于该初始分片索引文件为终端设备提供合适的目标分片索引文件。通过这种方式，就可以实现仅基于同一份媒体分片的数据源，就可以为不同类别的终端设备通过对应的目标分片集合，这样有效的区分各个不同类别的终端设备，不需要通过分门别类的存储多份媒体文件来为不同类别的终端设备提供相应的服务，相较于现有机制，明显降低服务器的存储压力。
可选的，在一些发明实施例中，在所述根据分析的结果为所述视频数据中的各个视频片段分别进行等级标识之后，在将所述视频数据进行转码之前，所述方法还包括：
若根据所述分析的结果确定所述视频数据中包含限制级视频片段，则对所述限制级视频片段对应的限制级分片的分片等级进行加密处理。
可选的，在一些发明实施例中，考虑到由于用户在观看视频时，可能会对视频的播放内容进行一些自身的感受的评论，尤其是由众多用户对该视频进行评论的情况，根据大数据分析，用户针对视频的整体评论存在客观性。所以服务器还可以将每个视频接入视频评论系统，然后基于用户针对媒体分片的评论来动态的更新媒体分片当前的分片索引文件。
具体来说，终端设备在所述根据所述目标分片索引文件从所述服务器下载所述目标分片集合之后，还可在播放所述目标分片集合中的分片时，获取用户对所述目标分片集合中的至少一个分片的评论，并将所述目标分片集合中的至少一个分片的评论发送给所述服务器，使得服务器可在获取所述媒体分片中各分片的评论后，根据所述终端设备对所述媒体分片中各分片的评论以及所述媒体分片中各分片的分片等级，确定所述媒体分片中各分片的实时分片等级，再根据所述媒体分片中各分片的实时分片等级更新所述媒体分片当前的分片索引文件。
可见，服务器通过同步关于视频的相关评论，更新媒体分片当前的分片索引文件。由于用户的评论内容会分为很多大类，服务器根据其中某个类的评论数较多的来判定该视频具备哪些特征，从而判定其应该满足哪几个限制等级，这样服务器就可以进一步更新(例如增加、修改、删除分片索引文件中的索引信息)对应各种限制等级的分片索引文件，这样就比后台的管理人员人工审核的效率要高出很多，并且能够摒弃主观色彩，使得审核视频的管理人员对各种限制等级的认定更加真实和准确。当视频被用户描述的越多， 其视频的等级信息更明显，也更客观，更准确。
举例来说，管理人员在服务器侧对视频对应的各分片进行评级时，一般是根据主观感受或者预定义的评级规则将各分片评定为普通级、保护级、辅导级和限制级等级别。但这些分片经过用户观看后，会基于真实的观看感受对各分片进行相应的评价，由于观看视频的用户数量庞大，所以用户对同一个分片的评价越多，则表示该分片的真实级别越明显趋于一个级别，并且评论也更客观。所以在这些用户对各分片进行评论后，管理人员可根据服务器侧所统计的对各分片的评论对本地存储的各分片再进行动态的调整，这样就能更准确、更客观的进行分级播放。例如，原先由管理人员评定的是保护级，有可能引入用户的评论机制后，该分片的级别最终可能会调整为限制级或者普通级。
又举例来说，服务器实时获取用户对各分片进行评论，然后可以基于贝叶斯公式对各分片的分片级别进行动态计算，然后将计算出的分片级别反馈给管理人员。然后，管理人员可根据服务器侧所统计的对各分片的评论对本地存储的各分片再进行动态的调整，这样就能更准确、更客观的进行分级播放。例如，原先由管理人员评定的是保护级，有可能引入用户的评论机制后，该分片的级别最终可能会调整为限制级或者普通级。本申请不对计算分片的分片级别的算法进行限定，只要能够使得计算出的分片级别趋于客观性即可。
一些实施方式中，服务器也可以在基于贝叶斯公式评分对各分片的分片级别进行动态计算后，确定出分片级别有更新的分片，然后自动的更新本地存储的分片的分片级别。
为便于理解，下面以视频分级传输对本申请的媒体分片处理方案进行说明。如图3所示，服务器包括媒体鉴定系统、存储系统、视频转码平台、切片系统和边缘节点，其中，管理人员将用户原创内容(英文全称：User Generated Content，英文简称：UGC)视频上传至存储系统后，由媒体鉴定系统对该UGC视频进行分析，具体来说，先截取UGC视频中的关键帧，然后对关键帧进行分析，然后根据UGC视频的视频内容对该UGC视频进行打分，例如血腥分数为8分、暴力分数10分等。可设置限制级片段的条件：视频片段的血腥分数超过8分，视频片段的暴力分数超过7分等，就可以认为这些视频片段为限制级片段。大众级片段的条件：视频片段的血腥分数低于8分，视频片段的暴力分数低于7分等，就可以认为这些视频片段为大众制级片段。
然后，媒体鉴定系统从UGC视频中分析出血腥分数超过8分的视频片段、 暴力分数超过7分的视频片段，并分别记录这些血腥分数或者暴力分数达到限制级条件的视频片段的索引，并将这些限制级片段进行裁剪。若该UGC视频为热播视频，那么，还可以进行进一步的人工审核，给其中不同的视频片段分别进行相关等级标识，并且在媒体鉴定系统中，将视频片段的等级记录到媒体描述文件中。
裁剪完后，将这些被裁剪的UGC视频接入到视频转码平台，将这些被裁剪的UGC视频转换为不同码率的视频，例如根据UGC视频的原始码率转换为标清、高清、超清和蓝光等，为用户提供多样化的视频源选择。
将UGC视频转码后，将转码后的各个码率的UGC视频接入到切片系统，切片系统根据媒体鉴定系统中的分片索引文件(也可称为媒体描述文件)将各个码率的UGC视频分别进行切片。切片后，每个码率的UGC视频都会切片为多个传送流(英文全称：Transport Stream，英文简称：TS)分片，然后，切片系统将每个分片的等级信息写入到分片索引文件中。本申请中的分片索引文件可以是m3u8文件，也可以是其它类型的文件，具体本申请不作限定。其中，TS是基于音视频信号和数据使用的一种通信协议的一种码流，其主要应用于实时传送的数字电视广播节目。TS由一道或多道节目组成,每道节目由一个或多个原始流和一些其他流复合在一起，包括视频流、音频流、节目特殊信息流和其他数据包。其中节目特殊信息流表有4种类型：节目关联表、节目映射表、网络信息表和条件访问表。TS可用于视/音频资料的保存、电视节目的非线性编辑系统及其网络等。
举例来说，服务器端存储的UGC视频当前的m3u8索引文件可以包含以下信息：
#EXTM3U
#EXT-X-VERSION:3
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-TARGETDURATION:3
#EXT-X-PLAYLIST-TYPE:VOD
#EXTINF:2.060,
00_rand.ts？level＝0
#EXTINF:2.960,
01_rand.ts？level＝2
#EXTINF:2.960,
02_rand.ts？level＝0
...........
#EXTINF:2.960,
0n_rand.ts？level＝10
在服务器端当前的m3u8索引文件中可包括UGC视频的版本、UGC视频中每个TS分片的播放时长和等级(level)信息，例如下表1所示的TS分片的等级说明：
等级(level) 说明
0 普遍级，一般观众皆可观赏
1 保护级，含有暴力内容，6岁以下儿童不宜观看
2 辅导级，含有血腥内容，12岁以下儿童不得观看
3 限制级，未满18岁之人不得观看。
… …
10 禁止级，禁止观看
表1
其中，例如00_rand.ts表示上述UGC视频中第一个TS分片，01_rand.ts表示上述UGC视频中第二个TS分片，其他类似，不作赘述。level＝0表示非限制级分片，level＝2所在的行对应图4所对应的实施例中新m3u8文件中的“01_rand.ts”，其表示该TS分片为限制儿童观看，level＝10表示限制会员观看。
在完成切片操作后，切片系统将各TS分片分发到边缘节点(英文全称：Broder Node，英文简称：BR)，其为一个特定对等群中的一个逻辑节点,该逻辑节点至少有一条通过对等群边界的链路，主要用于对接用户侧。
在媒体分发完成后，便开始发布上述UGC视频，其他视频的设置和分发过程可参考上述对UGC视频的说明，用户可以浏览到相关视频并进行观看。
当用户观看的视频属于大众等级时，服务器将视频的全部m3u8索引发送给客户端，客户端收到m3u8后，即可开始下载相关TS分片。由于m3u8没有被服务器修改，所以用户可以观看整部视频。
下面以观看上述UGC视频为例，图4为服务器处理客户端请求的一种流程图。用户请求下载上述UGC视频时，服务器确定该用户请求下载的UGC视频中包含限制级信息(参考上述表1)，若用户未登录账号，那么服务器则提 示用户进行账号登录；若用户不进行登录，则将初始m3u8文件中的大众级TS分片的分片索引信息重写到一个新m3u8文件,然后将新m3u8文件分发到客户端。这样由于客户端获取的新m3u8文件中不包含限制级TS分片的分片索引信息，所以该用户只能观看大众级的TS分片；但是对于客户端而言，则是体现出流畅的播放，但不播放限制级的TS分片，在客户端对于限制级TS分片的缺少并无感知。
当用户登录账号后，服务器还可判断用户的年龄或者用户等级，根据用户的年龄或者用户等级重写m3u8文件，过滤高于用户等级的TS分片索引信息，再将重写的m3u8文件发送给客户端，使得客户端根据接收到的m3u8文件下载对应的TS分片。一些实施方式中，实时的重写m3u8索引，还可以预先设置一张表，该表中可以包括用户等级、年龄段、TS分片索引信息之间的映射关系，或者还直接包括将用户等级、年龄段、TS分片索引信息映射到对应用户等级或年龄段的m3u8文件，在根据用户等级或年龄段判断该用户能够下载哪些TS分片，然后根据该表定位对应的m3u8文件，然后直接把预先存储的m3u8文件发给客户端，这样可以提高对客户端的播放请求的响应速度。
例如，若服务器判断当前请求下载上述UGC视频的用户年龄为10岁，那么可认为该用户不具备播放level＝2的TS分片的权限。那么，服务器可以将当前的m3u8文件中关于level＝2的TS分片的索引信息删除，形成一个新m3u8文件，新的m3u8文件可包括以下信息：
#EXTM3U
#EXT-X-VERSION:3
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-TARGETDURATION:3
#EXT-X-PLAYLIST-TYPE:VOD
#EXTINF:2.060,
00_rand.ts？level＝0
#EXTINF:2.960,
02_rand.ts？level＝0
...........
#EXTINF:2.960,
0n_rand.ts？level＝10
然后将新m3u8文件发送给该用户，使得该用户下载的TS分片中不会包 括该level＝2的TS分片。
由上可知，采用上述方案，本申请能够实现基于一份视频存储，就能满足不同用户的观看需求的目的，无需分别针对不用类别的用户分别存储不同的视频片源，一定程度上还能够减少服务器的符合，也能优化视频管理机制，以及提高对客户端的响应速度。
在一些实施方式中，由于用户在观看视频时，可能会对视频的播放内容进行一些自身的感受的评论，尤其是由众多用户对该视频进行评论的情况，根据大数据分析，用户针对视频的整体评论存在客观性。所以服务器还可以将每个视频接入视频评论系统，当视频被用户描述的越多，其视频的等级信息更明显，也更客观，更准确。服务器可以同步关于视频的相关评论，更新m3u8索引。用户的评论内容会分为很多大类，根据其中某个类的评论数较多的来判定该视频具备哪些特征，从而判定其应该满足哪几个限制等级，这样服务器就可以进一步更新(例如增加、修改、删除m3u8文件中的索引信息)对应各种限制等级的m3u8文件，这样就比后台的管理人员人工审核的效率要高出很多，并且能够摒弃主观色彩，使得审核视频的管理人员对各种限制等级的认定更加真实和准确。
以上对本申请中一种媒体播放方法进行说明，以下对执行上述媒体播放方法的服务器和终端设备分别进行描述。
一、参照图5，对服务器50进行说明，服务器50包括：
收发模块501，用于接收终端设备发送的播放请求，所述播放请求用于请求播放媒体分片；
处理模块502，用于根据所述播放请求查询所述媒体分片的分片索引文件，根据所述媒体分片的分片索引文件确定出目标分片集合，所述目标分片集合是指所述媒体分片中所述终端设备具备播放权限的分片；
确定与所述目标分片集合对应的目标分片索引文件；
通过所述收发模块501将所述目标分片索引文件发送给所述终端设备。
