Description

数据传输方法和装置、存储介质及电子装置
本申请要求于2017年11月16日提交中国专利局、优先权号为2017111414413、申请名称为“数据传输方法和装置、存储介质及电子装置”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
本申请涉及计算机领域，具体而言，涉及一种数据传输方法和装置、存储介质及电子装置。
背景技术
目前，在虚拟实境(Virtual Reality，简称VR)视频直播过程中，采用了360度球形全景图像来构成视频中的每一帧视频图像帧。其中，上述360度球形全景图像可以根据视角(Field of View，简称FOV)划分为不同的图像画面，从而实现当播放者的视角发生改变时，调整在设备的显示界面中所显示的图像画面，来达到使播放者深刻体验到身临其境的感觉的目的。
在播放客户端播放上述正在直播的视频流数据的过程中，通常是在获取到播放者视角发生变化后，主动向服务器请求获取播放者变化后的新视角所对应的视频流数据。也就是说，当播放者视角发生变化时，播放客户端每次都需重新启动请求程序，向服务器获取新视角对应的视频流数据，并缓冲一定时间段内的视频流数据。
通过上述多次向服务器请求并缓冲与变化后的视角相匹配的视频流数据的方式，来实现视频直播过程中的流数据传输，存在严重的传输延时问题，将大大影响视频直播的实时性。
针对上述的问题，目前尚未提出有效的解决方案。

具体实施方式
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分的实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都应当属于本申请保护的范围。
需要说明的是，本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
根据本申请实施例的一方面，提供了一种上述数据传输方法的实施例。作为一种可选的实施方式，该数据传输方法可以但不限于应用于如图1所示的应用环境中，上述服务器可以但不限于为分发服务器106。视频获取设备102实时获取需要播放的直播节目，并将获取到的直播节目根据要求 转换成N个视角的视角视频流数据，并将转换后的N个视角的视角视频流数据发送到状态最佳的媒体服务器104，媒体服务器104接收到转换的N个视角视频流数据后，根据不同的节目，将属于同一个节目的N个视角的视角视频流数据发送到同一个分发服务器106上，通过分发服务器106将与终端播放器108的当前播放视角匹配的视角视频流数据发送到终端播放器108上。其中，上述视频获取设备102与媒体服务器104与分发服务器106与播放客户端108之间的数据传递可以但不限于通过网络来完成。
在本实施例中，分发服务器106获取播放客户端的当前播放视角，在已缓存的视角视频流数据中，确定与当前播放视角匹配的当前播放视角视频流数据，并将当前播放视角视频流数据推送给播放客户端。由于本申请实施里中当播放客户端的播放视角改变后，不需要重新向分发服务器106发送获取新视角对应的视频流数据的请求，解决了视频直播过程中的流数据传输过程中存在的严重的传输延时问题，提高了视频直播的效率。
可选地，在本实施例中，上述播放客户端以包括但不限于以下至少之一：手机、平板电脑、笔记本电脑等设备；上述网络可以包括但不限于无线网络，其中，该无线网络包括：蓝牙、WIFI及其他实现无线通信的网络。上述只是一种示例，本实施例对此不做任何限定。
可选地，在本实施例中，选择状态最佳的媒体服务器可以但不限于通过以下条件：媒体服务器的当前任务负载、媒体服务器与视频获取设备的距离远近等，在此不做具体限定。
根据本申请实施例，提供了一种数据传输方法，如图2所示，该方法包括：
S202，服务器获取播放客户端的当前播放视角，其中，播放客户端用于播放被选中的直播节目的视频流数据；
S204，服务器在已缓存的视角视频流数据中，确定与当前播放视角匹配的当前播放视角视频流数据，其中，已缓存的视角视频流数据中包括与 直播节目对应的多个视角的视角视频流数据，多个视角包括当前播放视角；
S206，服务器将当前播放视角视频流数据推送给播放客户端。
可选地，在本实施例中，上述数据传输方法可以但不限于应用于虚拟实境(Virtual Reality，简称VR)视频直播过程中。例如，以VR视频直播为例，当播放者视角发生变化时，需要播放客户端主动向服务器发送请求，以获取新视角对应的视频流数据。然而，由于播放者视角的频繁变化，播放客户端需要频繁的向服务器发送请求，因此，容易造成流数据传输延时高的问题。而在本实施例中，通过服务器获取播放客户端的当前播放视角，并在已缓存的视角视频流数据中确定与当前播放视角匹配的当前播放视角视频流数据，并将当前播放视角视频流数据推送给播放客户端，从而实现了播放客户端的播放者视角发生变化后，服务器可以直接确定与当前播放视角匹配的当前播放视角视频流数据，并将该视频流数据推送给播放客户端，从而避免了每次播放者视角发生变化后都需要向服务器重新发送请求，达到了降低传输延时的效果。
可选地，上述数据传输方法可以但不限于通过图3所示的方法实现。如图3所示，媒体服务器302将视角视频流数据发送给分发服务器304，分发服务器304在收到视角视频流数据后，缓存视角视频流数据。当接收到播放客户端306发送的当前播放视角时，分发服务器304确定与播放视角匹配的当前播放视角视频流数据，并向播放客户端306推送当前播放视角视频流数据。当播放客户端306的当前播放视角发生变化时，重复步骤S305，分发服务器收到改变后的当前播放视角后，将视角视频流数据变化为与改变后的当前播放视角匹配的视角视频流数据，并重复步骤S309，将变化后的视角视频流数据推送给播放客户端306。
可选地，可以但不限于通过提前设置的方法获得当前播放视角；或者是通过检测的方式获得当前播放视角。例如如图4所示，当人佩戴VR设备之后，可视范围为一个球形，此时，服务器可以通过将可视范围分区的方法获取当前播放视角。对于获取当前播放视角的方法，在此不做具体限 定。
具体如图5所示，图5左侧为一个可视范围的全景图，此时，服务器将该全景图分成图5右侧的九个视角区域，根据当前播放视角所在的视角区域，确定与当前播放视角匹配的视角视频流数据，并将视角视频流数据推送给播放客户端。
可选地，上述通过服务器对可视范围进行分区的方法获取当前播放视角仅仅为一种可行的实施例，对于获取当前播放视角的手段本实施例并不做具体限定。
可选地，可以通过建立视角-视角视频流数据表的方法确定与当前播放视角匹配的当前播放视角视频流数据。继续以图5中对视角的分区进行说明，具体如表1所示，视角所在的位置为区域1时，播放客户端将区域1发送给分发服务器，分发服务器根据视角所在的区域，将与视角所在区域对应的视角视频流数据1推送给播放客户端。当视角处于区域2或者区域3时，具体方法与视角处于区域1时相同，在此不做赘述。
表1
视角区域 视角视频流数据
区域1 视角视频流数据1
区域2 视角视频流数据2
区域3 视角视频流数据2
可选地，上述服务器确定与当前播放视角匹配的当前播放视角视频流数据包括服务器根据直播节目的节目标识获取与节目标识对应的多个视角的视角视频流数据。
可选地，服务器可以对播放客户端所播放的直播节目进行编号，当播放直播节目时，播放客户端将直播节目的编号发送给服务器，服务器根据直播节目的编号，从已缓存的视角视频流数据中获取与直播节目的编号向 对应的多个视角的视角视频流数据。当获取到与当前直播节目向对应的多个视角的视角视频流数据后，服务器再根据获取到的当前播放视角确定与当前播放视角匹配的当前播放视角视频流数据。
需要说明的是，上述对直播节目进行编号仅仅为一种可选示例，对于获取直播节目的编号有多种方式，在此不做具体限定。
可选地，在服务器获取播放客户端检测的当前播放视角之前，服务器还可以接受节目标识所标识直播节目对应的多个视角的视角视频流数据并缓存。
可选地，服务器接收到媒体服务器发送的节目标识对应的多个视角的视角视频流数据后，缓存在预定时间段内的多个视角的视角视频流数据。其中，视角视频流数据中的每一个视频帧中都携带有视角视频流对应的视角的视角标识。继续以图5进行说明，媒体服务器发送与节目标识对应的九个视角的视角视频流数据，当服务器接收到九个视角的视角视频流数据后，缓存预定时间段内的九个视角的视角视频流数据。
可选地，服务器可以以分钟为单位，缓存四个视角的视角视频流数据的每分钟的前5秒钟。以一个视角的视角视频流数据为例，视频流数据时长为5分钟，可以缓冲0-5秒，60-65秒，...，240-245秒。
可选地，可以以当前播放视角的视角号作为每一个视频帧中携带的视角标识。例如，继续以图进行说明，当前播放视角所在的区域为区域2，对应的视角视频流数据中的每一个视频帧做携带的视角标识可以为数字2，或者为二进制数字0010，在此不作具体限定。
可选地，服务器可以根据当前播放视角切换的时间，将当前播放视角视频流数据切换为变化后的视角视频流数据。
可选地，当当前播放视角切换之后，服务器获取当前播放视角切换后的视角，根据当切换后的视角，将当前播放视角视频流数据切换为变化后的视角视频流数据，并将变化后的视角视频流数据推送给播放客户端。
通过本申请实施例，采用服务器获取播放客户端当前播放视角，其中，播放客户端用于播放被选中的直播节目的视频流数据；服务器在已缓存的视角视频流数据中，确定与当前播放视角匹配的当前播放视角视频流数据，其中，已缓存的视角视频流数据中包括与直播节目对应的多个视角的视角视频流数据，多个视角包括当前播放视角；服务器将当前播放视角视频流数据推送给播放客户端的方式，从而实现了提高视频的播放效率的技术效果，即，通过根据当前播放视角直接确定与当前播放视角匹配的直播节目的视频流数据，进而解决了多次向服务器请求与变化后的视角相匹配的视频流数据所导致的传输延时的技术问题。
作为一种可选的方案，服务器确定与当前播放视角匹配的当前播放视角视频流数据包括：
S1，服务器获取播放客户端所播放的直播节目的节目标识；
S2，服务器从已缓存的视角视频流数据中获取与节目标识对应的多个视角的视角视频流数据；
S3，服务器确定与当前播放视角匹配的当前播放视角视频流数据。
例如，可以通过建立播放客户端地址-节目标识-节目-视角视频流数据对应表。如表2所示，播放客户端正在播放的节目为节目1，服务器根据节目1对应的节目标识，确定与节目1对应的多个视角视频流数据，再根据当前播放视角(如视角1)将当前播放视角的视角视频流数据(如视角视频流数据1)按照播放客户端地址发送给对应的播放客户端。
表2
播放客户端地址 节目标识 视角 当前播放视角视频流数据
192.168.1.5 节目1 视角1 视角视频流数据1
192.168.1.3 节目2 视角2 视角视频流数据2
通过本申请实施例，服务器可以根据当前节目的节目标识快速定位到 与该节目标识对应的多个视角的视角视频流数据，从而节省了获取视角视频流数据的时间。
作为一种可选的方案，服务器获取播放客户端的当前播放视角之前，还包括：
S1，服务器接收媒体服务器发送的节目标识所标识的直播节目对应的多个视角的视角视频流数据；
S2，服务器缓存在预定时间段内多个视角的视角视频流数据，其中，视角视频流数据中的每一个视频帧中携带有视角视频流数据所对应的视角的视角标识。
