- the invention relates to the field of communications, and in particular to a method for realizing picture-in-picture playing and a picture-in-picture playing device.
- the current live video process not only provides a variety of electronic program navigation pages, but also provides services such as on-demand, TV viewing, personal recording, information browsing and games, and has a variety of interactive functions, and the entire live broadcast process It is divided into two stages: live broadcast and time-shifted playback (that is, any playback of live content at any time in the past).
- live broadcast and time-shifted playback that is, any playback of live content at any time in the past.
- the playback of the two phases can only be controlled by the switching of the timeline.
- a specific scenario in which the playback of the time slot is controlled by the time axis switching is that the user may need to pause playing the currently live content (for example, the user has something to leave for a while), and when the user comes back to resume playback, the playback is paused.
- live content if you want to preview the content currently being broadcast, you must drag the playhead on the timeline of the current playback page to the moment you are currently playing. After the preview, if the user wants to go back to the previous play page, then the timeline needs to be dragged back, so that the video should be frequently switched during the live broadcast. This frequent switching live broadcast and playback will increase the number of scheduling requests. Increase the burden on the server.

本发明涉及通信领域，尤其涉及一种实现画中画播放的方法及画中画播放装置。
随着科学技术的日益发展和网络多媒体的广泛普及，用户对视频观看的体验感要求越来越高。现阶段的视频直播过程，不仅能够提供丰富多彩的电子节目导航页面，还能提供点播、电视回看、个人录制、信息浏览和游戏等服务，并且具有多种交互性的功能，而且整个直播流程分为正在直播和时移回放(即任意回放过去任意时间的直播内容)两个阶段，两个阶段的播放只能通过时间轴的切换进行控制。
例如，通过时间轴的切换控制上述两个阶段的播放的一个具体场景为：用户可能需要暂停播放当前直播的内容(例如用户有事离开片刻)，当用户回来恢复播放以后播放的则是暂停过程中直播过的内容，若想要预览当前正在直播的内容，就必须拖动当前播放页面的时间轴上的播放头至当前正在直播的时刻。预览后，用户若想回到之前的播放页面，则又需将时间轴拖回，这样就使得视频在直播过程中要进行频繁的切换，这种频繁的切换直播和回放会增加调度请求的次数，加剧服务器的负担。

为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为实施例一的实现画中画播放的方法的流程示意图；
图2为实施例二的实现画中画播放的方法的流程示意图；
图3为实施例三的画中画播放装置结构示意图。
下面将结合本发明实施例中的附图，对本发明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发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
实施例一
本发明的实施例提供一种实现画中画播放的方法，如图1所示，该方法包括：
101、画中画播放装置获取画中画播放功能的触发指令，并记录多媒体文件当前的播放进度。
其中，获取画中画播放功能的触发指令，具体包括：响应于用户的第
一操作，获取触发指令，第一操作为用户触发画中画播放功能按键；或者，响应于用户的第二操作，获取触发指令，第二操作为用户触发暂停功能按键；或者，响应于用户的第三操作，获取触发指令，第三操作为用户触发回放功能按键。
具体的，当用户希望在某视频网站观看一场世界杯比赛的直播，那么用户可以通过多种方式实现画中画播放装置的画中画功能，其中，至少包括以下三种：
在第一种实现方式中，当用户操作当前视频播放界面的工具栏中的画中画播放功能按键(具体可以为用户点击画中画播放功能按键)时，画中画播放装置响应于用户操作获取触发指令，此时画中画播放装置内的处理程序会接受到相应触发指令，并将该触发指令发送给画中画播放装置内核，画中画播放装置内核会指示打开画中画播放功能，显示除当前播放视频外的画中画播放窗口，画中画播放窗口内播放正在直播的世界杯比赛。
其中，画中画播放装置内核用于对以数字形式存储的视频或音频文件进行解码，缓冲，频率转换等涉及音质的计算。
在第二种实现方式中，当用户对当前播放的世界杯直播进行暂停操作时，画中画播放装置响应于用户操作获取触发指令，此时画中画播放装置内的处理程序会接受到相应触发指令，并将该触发指令发送给画中画播放装置内核，画中画播放装置内核会指示打开画中画播放功能，显示除当前播放视频外的画中画播放窗口，画中画播放窗口内播放正在直播的世界杯比赛。
在第三种实现方式中，当用户当前播放的世界杯直播进行回放操作，例如操作快退键或者将移动当前播放界面内的时间轴上的播放头至已经播放过的视频内容时，画中画播放装置响应于用户操作获取触发指令，此时画中画播放装置内的处理程序会接受到相应触发指令，并将该触发指令发送给画中画播放装置内核，画中画播放装置内核会指示打开画中画播放功能，显示除当前播放视频外的画中画播放窗口，画中画播放窗口内播放正在直播的世界杯比赛。
另外，本发明实施例中的多媒体文件当前的播放进度，为画中画播放
装置获取画中画播放功能的触发指令时所指示的当前多媒体文件的播放位置。例如，用户在观看某电视剧第一集第二十二分触发画中画播放功能，此时画中画播放装置收到该用户的触发指令后记录当前多媒体文件的播放进度即第一集第二十二分钟。
102、画中画播放装置发送触发指令至调度服务器。
具体的，用户在观看视频节目时，调度服务器会获取当前的视频播放数据，控制参数以及服务地址等参数，当调度服务器在接收到画中画播放装置内核发送来的相应的触发指令后，会对当前的视频播放数据，控制参数以及服务地址等参数进行分析，确定当前情况下可使用的画中画播放模式进行播放。
103、画中画播放装置接收来自调度服务器所指示的可使用的画中画播放模式的消息。
其中，预置的画中画播放模式包括对等连接P2P模式、路由选择表维护协议RTMP模式、物理切片模式中的至少一个。
104、画中画播放装置按照预设规则在可使用的画中画播放模式中确定需使用的画中画播放模式。
具体的，若可使用的画中画播放模式有多种时，画中画播放装置根据预设的优先级顺序选择画中画播放模式。其中，P2P播放模式的优先级高于物理切片播放模式，物理切片播放模式的优先级高于RTMP播放模式。画中画播放装置确定可使用的画中画播放模式中优先级最高的画中画播放模式，并将优先级最高的画中画播放模式作为需使用的画中画播放模式。
例如，用户在线收看直播的中国好声音节目，在画中画播放装置获取画中画播放功能的触发指令，经过调度服务器对当前的视频播放数据，控制参数以及服务地址等参数进行分析后，确定P2P播放模式、物理切片播放模式及RTMP播放模式都为可使用的画中画播放模式。此时，画中画播放装置根据预设的优先级顺序，先使用P2P播放模式进行直播数据加载，若加载失败，则选择物理切片模式进行直播数据加载，若加载成功，则在画中画播放窗口播放中国好声音的直播视频。
105、画中画播放装置根据预置的画中画播放窗口的配置参数，创建画
中画播放窗口，进而根据记录的播放进度，在画中画播放窗口中采用需使用的画中画播放模式播放多媒体文件。
其中，预置的画中画播放窗口的配置参数，具体包括：指示画中画播放窗口的可见性、播放时间显示、窗口大小、文案设置以及拖动设置的相应的数据。也就是说，用户可以在画中画播放窗口内对以上信息进行设置，例如调整画中画播放窗口的大小满足用户的观看习惯等。
具体的，画中画播放装置内核会根据预置的画中画播放窗口的配置参数，建立画中画播放窗口，当获取用户指令，确定画中画播放模式后，画中画播放装置会显示被隐藏关闭的画中画播放窗口，在播放窗口内以相应的播放模式加载直播数据进行视频直播播放。
本发明实施例提供的一种实现画中画播放的方法，在使用当前窗口播放当前多媒体文件的过程中，首先获取画中画播放功能的触发指令，进一步地，发送触发指令至调度服务器，以使调度服务器根据触发指令在预置的画中画播放模式中确定可使用的画中画播放模式，预置的画中画播放模式包括对等连接P2P模式、路由选择表维护协议RTMP模式、物理切片模式中的至少一个，当接收到来自调度服务器的指示可使用的画中画播放模式的消息，则按照预设规则在可使用的画中画播放模式中确定需使用的画中画播放模式，最后，根据预置的画中画播放窗口的配置参数，创建画中画播放窗口，进而采用需使用的画中画播放模式在画中画播放窗口中继续播放当前多媒体文件。该方案通过获取用户的触发指令，在直播页面内创建画中画窗口，进而调用已确定的直播模式在画中画窗口内播放直播内容，实现了在同一播放页面内直播内容以及用户指定内容的同时播放功能，减轻了服务器由于频繁响应直播和回放任务所带来的不必要开销，解决了用户观看直播视频进行时移回放时想要预览直播内容需频繁切换的问题。
实施例二
本发明的实施例提供一种实现画中画播放的方法，如图2所示，该方法包括：
201、画中画播放装置根据预置的画中画播放窗口的配置参数，建立画中画播放窗口。
其中，预置的画中画播放窗口的配置参数，具体包括：指示画中画播放窗口的可见性、播放时间显示、窗口大小、文案设置以及拖动设置的相应的数据。也就是说，用户可以在画中画播放窗口内对以上信息进行设置，例如调整画中画播放窗口的大小满足用户的观看习惯等。
另外，此处建立的画中画播放窗口，只有在获取触发指令以及确定画中画播放模式后才会打开，以使得画中画播放窗口中继续播放当前多媒体文件。在画中画播放功能没有实现的时候，画中画窗口一直处于隐藏关闭状态。
202、画中画播放装置对配置参数进行初始化，以指示可以获取画中画播放功能指令。
具体的，在执行画中画播放功能前，画中画播放装置需要对配置参数进行初始化操作，完成对画中画播放装置内部程序系统的初始部署，以使得用户可以对画中画播放装置进行操作指示。
203、画中画播放装置响应于用户操作播放当前多媒体文件数据。
具体的，当用户选择观看某一在线直播视频时，比如一场体育赛事直播，在当前播放界面内会播放体育赛事，同时，调度服务器会获取当前的视频播放数据，控制参数以及服务地址等参数，用于后续画中画播放功能的应用。
204、响应于用户操作当前视频播放界面的工具栏中的画中画播放功能按键的操作时，画中画播放装置获取到触发指令，执行步骤207。
具体的，例如用户希望在某视频网站观看一场世界杯比赛的直播，当用户操作当前视频播放界面的工具栏中的画中画播放功能按键(具体可以为用户点击画中画播放功能按键)时画中画播放装置响应于用户操作获取触发指令，此时画中画播放装置内的处理程序会接受到相应触发指令发送给画中画播放装置内核，画中画播放装置内核会指示打开画中画播放功能，显示除当前播放视频外的画中画播放窗口，画中画播放窗口内播放正在直播的世界杯比赛。
205、响应于用户对当前播放视频进行暂停操作时，画中画播放装置获取到触发指令，执行步骤207。
例如，当用户对当前播放的奥运会比赛直播进行暂停操作时，画中画播放装置响应于用户操作获取触发指令，此时画中画播放装置内的处理程序会接受到相应触发指令发送给画中画播放装置内核，画中画播放装置内核会指示打开画中画播放功能，显示除当前播放视频外的画中画播放窗口，画中画播放窗口内播放正在直播的奥运会比赛。
206、响应于用户对当前播放视频进行回放操作时，画中画播放装置获取到触发指令。
其中，本实施例中的回放操作，包括操作快退键或者将移动当前播放界面内的时间轴上的播放头至已经播放过的视频内容。
例如，当用户操作快退键或者将移动当前播放界面内的时间轴上的播放头至已经播放过电视剧在线直播的视频内容时，画中画播放装置响应于用户操作获取触发指令，此时画中画播放装置内的处理程序会接受到相应触发指令发送给画中画播放装置内核，画中画播放装置内核会指示打开画中画播放功能，显示除当前播放视频外的画中画播放窗口，画中画播放窗口内播放正在直播的电视剧。
这里要说明的是，步骤204至步骤206没有时间先后顺序，选择其中一个步骤就可以完成本方案，此处不做限定。
207、画中画播放装置记录多媒体文件当前的播放进度。
本发明实施例中的多媒体文件当前的播放进度，为画中画播放装置获取画中画播放功能的触发指令时所指示的当前多媒体文件的播放位置。例如，用户在观看某直播球赛至第三十二分触发播放页面的暂停按键，此时画中画播放装置收到该用户的触发指令后记录当前多媒体文件的播放进度即第三十二分钟。
208、画中画播放装置发送触发指令至调度服务器，以使调度服务器根据触发指令在预置的画中画播放模式中确定可使用的画中画播放模式。
其中，预置的画中画播放模式包括对等连接P2P模式、路由选择表维护协议RTMP模式、物理切片模式中的至少一个。
具体的，用户在观看视频节目时，调度服务器会获取当前的视频播放
数据，控制参数以及服务地址等参数，当调度服务器在接收到画中画播放装置内核发送来的相应的触发指令后，会对当前的视频播放数据，控制参数以及服务地址等参数进行分析，确定当前情况下可使用的画中画播放模式进行播放。
209、画中画播放装置若接收到来自调度服务器的指示可使用的画中画播放模式的消息，则按照预设规则在可使用的画中画播放模式中确定需使用的画中画播放模式。
具体的，若可使用的画中画播放模式有多种时，画中画播放装置根据预设的优先级顺序选择画中画播放模式。其中，P2P播放模式的优先级高于物理切片播放模式，物理切片播放模式的优先级高于RTMP播放模式。画中画播放装置确定可使用的画中画播放模式中优先级最高的画中画播放模式，并将优先级最高的画中画播放模式作为需使用的画中画播放模式。
进一步地，画中画播放装置判断在所述画中画播放窗口中采用所述需使用的画中画播放模式播放所述多媒体文件是否成功，若判断结果为不成功，画中画播放装置则采用所述可使用的画中画播放模式中的优先级次高的画中画播放模式，并根据记录的所述播放进度，在所述画中画播放窗口中采用所述需使用的画中画播放模式播放所述多媒体文件。
例如，用户在线收看直播的中国好声音节目，在画中画播放装置获取画中画播放功能的触发指令，经过调度服务器对当前的视频播放数据，控制参数以及服务地址等参数进行分析后，确定P2P播放模式、物理切片播放模式及RTMP播放模式都为可使用的画中画播放模式。此时，画中画播放装置根据预设的优先级顺序，先使用P2P播放模式进行直播数据加载，若加载失败，则选择物理切片模式进行直播数据加载，若加载成功，则在画中画播放窗口播放中国好声音的直播视频。
210、画中画播放装置根据预置的画中画播放窗口的配置参数，创建画中画播放窗口，进而根据记录的播放进度，在画中画播放窗口中采用需使用的画中画播放模式播放多媒体文件。
具体的，画中画播放装置内核会根据预置的画中画播放窗口的配置参数，建立画中画播放窗口，当获取用户指令，确定画中画播放模式后，画
中画播放装置会显示被隐藏关闭的画中画播放窗口，在播放窗口内以相应的播放模式加载直播数据进行视频直播播放。
例如，用户在线观看央视春晚直播视频，当用户暂停当前直播视频时，画中画播放装置获取触发指令，调度服务器在接收到画中画播放装置内核发送来的相应的触发指令后，会对当前的视频播放数据，控制参数以及服务地址等参数进行分析，确定当前情况下可使用的画中画播放模式为P2P模式和物理切片模式，此时，画中画播放装置根据预设的优先级顺序，使用P2P播放模式进行直播数据加载，加载成功后，画中画播放装置会显示被隐藏关闭的画中画播放窗口，在播放窗口内以相应的播放模式进行央视春晚视频直播播放，若用户此时操作关闭画中画播放功能按键，那么画中画播放装置会停止P2P播放模式的数据加载并隐藏画中画播放窗口。
本发明实施例提供的一种实现画中画播放的方法，在使用当前窗口播放当前多媒体文件的过程中，首先获取画中画播放功能的触发指令，进一步地，发送触发指令至调度服务器，以使调度服务器根据触发指令在预置的画中画播放模式中确定可使用的画中画播放模式，预置的画中画播放模式包括对等连接P2P模式、路由选择表维护协议RTMP模式、物理切片模式中的至少一个，当接收到来自调度服务器的指示可使用的画中画播放模式的消息，则按照预设规则在可使用的画中画播放模式中确定需使用的画中画播放模式，最后，根据预置的画中画播放窗口的配置参数，创建画中画播放窗口，进而采用需使用的画中画播放模式在画中画播放窗口中继续播放当前多媒体文件。该方案通过获取用户的触发指令，在直播页面内创建画中画窗口，进而调用已确定的直播模式在画中画窗口内播放直播内容，实现了在同一播放页面内直播内容以及用户指定内容的同时播放功能，减轻了服务器由于频繁响应直播和回放任务所带来的不必要开销，解决了用户观看直播视频进行时移回放时想要预览直播内容需频繁切换的问题。
