交叉引用
本申请要求于2015年12月30日提交中国专利局、申请号为201511029800.7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
本专利申请涉及虚拟现实技术领域，特别涉及一种视频的多点同屏播放方法及系统。
背景技术
发明人在实现本发明的过程中发现，随着科学技术的发展，虚拟现实设备在军事训练、虚拟驾驶和虚拟城市等项目中具有广泛的应用。头盔类项目是当下非常热门的项目，此类头盔项目目前最大的特点在于360度全景显示，这种天然的全景显示方式对家庭娱乐类不同终端的同屏同显给出比较好的解决方案。但是，目前在头盔上播放的视频数据都是特制的视频数据，这些特制的视频数据(如视频、游戏、剪辑类等)均由终端提前对360度场景做编辑和处理，再传输给虚拟现实设备进行播放。如，对音乐会等实时场景来说，传输给虚拟现实设备的视频数据均由终端对多角度摄像机采集的数据进行实时编辑和处理。但是，现有技术中的虚拟现实设备只能对单个视频数据进行处理，而对不是同场的实时数据，目前还没有能直接在头盔上无缝播放，功能较为单一，用户体验较差。例如家里有四个不同设备同时播放不同内容，目前没有给出在VR头盔上将此四路信号同时播放的方法。
发明内容
本发明部分实施例的目的在于提供一种视频的多点同屏播放方法及系统，使得VR(Virtual Reality，虚拟现实)设备可以同时播放多个源的视频数据，实现了多个视频数据间的360°无缝播放，从而为用户提供了更好的播放体验。
为解决上述技术问题，本发明的实施方式提供了一种视频的多点同屏播放方法，包含以下步骤：
至少2台终端将视频数据实时同步传输到VR设备；
VR设备将显示屏划分成若干显示区域；
VR设备根据对显示屏的划分结果，对来自不同终端的视频数据进行播放格式的转换处理；
VR设备将来自不同终端的视频数据同时投射到不同的显示屏进行播放；其中，一个终端的视频数据至少投射到一个显示区域。
本发明的一个实施例提供了一种计算机可读存储介质，包括计算机可执行指令，所述计算机可执行指令在由至少一个处理器执行时致使所述处理器执行上述方法。
本发明的实施方式还提供了一种视频的多点同屏播放系统，包含：VR设备和至少2台终端，至少2台终端将视频数据实时同步传输到VR设备；
VR设备进一步包含：划分模块，数据整合模块和投射模块；
划分模块用于将显示屏划分成若干显示区域；
数据整合模块用于根据对显示屏的划分结果，对来自不同终端的数据进行播放格式的转换处理；
投射模块用于将来自不同终端的视频数据同时投射到不同的显示区域进行播放；其中，一个终端的视频数据至少投射到一个显示区域。
本发明实施方式相对于现有技术而言，至少2台终端将视频数据实时同步传输到VR设备，VR设备将显示屏划分成若干显示区域，VR设备根据对显示屏的划分结果，对来自不同终端的视频数据进行播放格式的转换处理，VR设备将来自不同终端的视频数据同时投射到不同的显示区域进行播放。其中，一个终端的视频数据至少投射到一个显示区域。通过划分显示屏获得多个显示区域的方式，使得VR设备在同时接收来自多个终端所传输的视频数据时，对接收的视频数据进行调节处理，以使得视频数据的屏幕尺寸与显示区域的大小相匹配，从而将来自各终端的视频数据铺满整个显示屏进行显示，以实现360°画面的无缝结合。并且，VR设备利用所划分的显示区域对多个视频数据进行同时播放，实现了多个视频数据的无缝播放，从而为用户提供了更好的播放体验。
在一个实施例中，在VR设备将显示屏划分成若干显示区域的步骤中，VR设备根据终端的数目平均划分显示屏，使得VR设备显示屏的所有区域均能够被使用，避免了资源浪费。并且，在每个显示区域的尺寸相同的情况下，这种划分方式为每个视频数据都提供了当前最大的屏幕宽度。
在一个实施例中，在VR设备将显示屏划分成若干显示区域的步骤中，VR设备将显示屏划分成与终端数目相等的显示区域；其中，显示区域的大小可调节；并且，处于用户正对方向的显示区域的尺寸大于其余方向的显示区域的尺寸。通过这种方式，从而使得用户正在观看的视频数据具有较大的屏幕宽度，以能够为用户提供较佳的可视角度，使用户的观看体验得到提高。
在一个实施例中，在VR设备将来自不同终端的视频数据同时投射到不同的显示区域进行播放的同时，VR设备播放的声音与处于用户正对方向的显示区域播放的视频相对应，从而避免了其他视频数据的声音对用户正在观看的视频数据的声音产生干扰，为用户提供了更好的播放体验。
在一个实施例中，在至少2台终端将视频数据实时同步传输到VR设备 的步骤中，不同终端采用不同的无线传输协议传输数据，以提高视频数据的传输速度，使得VR设备尽可能快的接收到视频数据，为提高用户体验提供了可能。

本发明的第一实施方式涉及一种视频的多点同屏播放方法，具体流程如图1所示。本实施方式的应用场景为：用户正使用至少2台终端将视频数据实时同步传输到VR设备，其中终端可以是电脑、手机、平板电脑、相机、电视或视频盒子等电子设备，终端可以通过数据线传输视频数据，也可以通过无线传输协议传输视频数据，仅以此举例为限，在此不做任何限定。VR设备做为显示终端和处理终端，对来自不同终端的所有数据组合和处理，达到不同设备间的360度画面的无缝结合。
步骤101，VR设备将显示屏划分成若干显示区域。
其中，显示屏的划分数目可以为VR设备的默认设置，默认设置中的数值可以由用户或出厂商预先设置并保存在VR设备中。
而在本实施方式中，VR设备根据终端的数目平均划分显示屏，以使得VR设备显示屏的所有区域均能够被使用，避免了资源浪费。并且，在每个显示区域的尺寸相同的情况下，这种划分方式为每个视频数据都提供了当前最大的屏幕宽度。比如，以VR头盔与多台终端为例来说：
1、假设同时有6台不同设备同时播6个节目，此时将此6台设备的数据同步传输到VR头盔，这样每路设备占据60度的画面，随时随地可看不同场次的节目。
2、假设同时有4台不同设备同时播放4个节目，此时将此4台设备的数据同步传输到VR头盔，这样每路设备占据90度的画面，随时随地可看不同场次的节目。
3、假设同时有3台不同设备同时播放3个节目，此时将此3台设备的数据同步传输到VR头盔，这样每路设备占据120度的画面，随时随地可看不同场次的节目。
4、假设同时有2台不同设备同时播放2个节目，此时将此2台设备的数据同步传输到VR头盔，这样每路设备占据180度的画面，随时随地可看不同场次的节目。
步骤102，VR设备对来自不同终端的视频数据进行播放格式的转换处理。
由于不同终端所播放视频的播放格式不同，因此，为了使来自不同终端的视频数据适于VR设备播放，需要进行格式转换。这里所说的播放格式的转换处理包括但不限于：尺寸的任意缩放，视频文件格式的转换，各视频位置的任意排布等。比如，VR设备根据所划分的显示区域的大小，对接收的 视频数据进行调节，以使得视频数据的屏幕尺寸与显示区域的大小相匹配，从而将来自各终端的视频数据铺满整个显示屏，实现360°画面的无缝结合。再比如，将某一显示区域进行拆分，以适应显示更多终端的视频需求。
步骤103，VR设备将来自不同终端的视频数据同时投射到不同的显示区域进行播放。
具体的说，VR设备同时将来自不同终端的视频数据分别投射到已划分好的各显示区域中，并进行播放。其中，VR设备所播放的视频数据可以携带有声音。
值得一提的是，当VR设备所播放的视频数据携带有声音时，则VR设备当前播放的声音与处于用户正对方向的显示区域播放的视频相对应，从而避免其他视频数据的声音对用户正在观看的视频数据的声音产生干扰，为用户提供更好的播放体验。其中，用户正对方向的获取方法可以是：由用户直接对自己正对方向的显示区域进行选择；或者VR设备上设有位置传感器和杜比的立体全景声技术，采用位置传感器检测用户正对方向，所以用户只会听到正对方向的视频声音，这样能避免不同视频内容的干扰，达到完美体验。本实施方式仅以此举例，任何用户正对方向的获取方法均在本发明的保护范围之内。
不难看出，本实施方式中，通过划分显示屏获得多个显示区域的方式，使得VR设备在同时接收来自多个终端所传输的视频数据时，对接收的视频数据进行组合处理，以使得视频数据的屏幕尺寸与显示区域的大小相匹配，从而将来自各终端的视频数据铺满整个显示屏进行显示，以实现360°画面的无缝结合。并且，VR设备利用所划分的显示区域对多个视频数据进行同时播放，实现了多个视频数据的无缝播放，从而为用户提供了更好的播放体验。
此外，值得说明的是，多台终端将视频数据实时同步传输到VR设备过 程中，可以相同的传输协议进行传输；也可以某些终端采用相同传输协议进行传输，而其他终端采用不同的传输协议进行传输；还可以使得不同终端采用不同的无线传输协议将视频数据传输给VR设备。也就是说，VR设备可以根据需要采用相同或者多种传输协议与终端进行数据传输，以使得VR设备能够尽可能快的接收到视频数据，为提高用户体验提供了可能。如，VR设备具有蓝牙模块及无线网卡，则手机可以通过蓝牙模块与VR设备建立蓝牙通信连接，从而进行数据传输；同时，电脑可以通过wifi与VR设备建立无线局域网，从而进行数据传输。这样，VR设备利用多个接口同时接收视频数据，实现了多个视频数据的并发上传，有效地缩短了传输多个视频数据所需要的时间。此外，本发明对传输协议的具体类型不做限制，目前所有的传输协议均能用于本发明。
上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些步骤进行拆分，分解为多个步骤，只要包含相同的逻辑关系，都在本专利的保护范围内；对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其算法和流程的核心设计都在该专利的保护范围内。
本发明的第二实施方式涉及一种视频的多点同屏播放方法。第二实施方式在第一实施方式的基础上加以改进，主要改进之处在于：在本发明第二实施方式中，显示区域的大小可调节，并且，VR设备在处于用户正对方向的显示区域的尺寸大于其余方向的显示区域的尺寸，从而能够为用户提供较佳的可视角度，提高了用户的观看体验。
本实施方式中，VR设备将显示屏划分成与终端数目相等的显示区域，且显示区域的大小可调节，为满足用户观看需求提供了可能。
其中，用户可以手动地对显示区域的大小进行调节。如，用户通过控制装置发送调节指令给VR设备，VR设备根据接收到的调节指令对显示区域的 大小进行调节，从而满足用户的观看需求。也可以默认设置正对用户方向的显示区域较大，其余方向则平分显示，一旦某视频转为用户正对方向，则增大该显示区域，将之前用户正对方向的显示区域缩小，使得用户正对方向的显示区域始终保持较佳的尺寸，为用户提供较佳的观看感受。
此外，本实施方式中，还令VR设备在处于用户正对方向的显示区域的尺寸大于其余方向的显示区域的尺寸，从而使得用户正在观看的视频数据具有较大的屏幕宽度，以能够为用户提供较佳的可视角度，使用户的观看体验得到提高。比如，目前科学实验发现，人两眼重合视域有124°，在人眼观看到的范围内，只有124°视角内的物体才有立体感。人眼的视角极限大约为垂直方向150度，水平方向230度，如果在这个视角范围内都是屏幕，就会给人一种身临其境的感觉。因此，VR设备可以为用户提供的正对方向的显示区域的尺寸可以为垂直方向150度，水平方向230度，以使得用户观看的真实感较强，获得较佳的观看体验。
本发明第三实施方式涉及一种视频的多点同屏播放系统，如图2所示，包含：VR设备和至少2台终端，至少2台终端将视频数据实时同步传输到VR设备。
VR设备包含：划分模块，数据整合模块、投射模块和声音播放模块，如图3所示。其中，划分模块用于将显示屏划分成若干显示区域，本实施方式中，划分模块可以根据终端的数目平均划分显示屏。数据整合模块用于根据对显示屏的划分结果，对来自不同终端的数据进行播放格式的转换处理。投射模块用于将来自不同终端的视频数据同时投射到不同的显示屏进行播放；其中，一个终端的视频数据至少投射到一个显示区域。声音播放模块播放的声音与处于用户正对方向的显示区域播放的视频向对应。
不难发现，本实施方式为与第一实施方式相对应的系统实施例，本实施方式可与第一实施方式互相配合实施。第一实施方式中提到的相关技术细节 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第一实施方式中。
值得一提的是，本实施方式中所涉及到的各模块均为逻辑模块，在实际应用中，一个逻辑单元可以是一个物理单元，也可以是一个物理单元的一部分，还可以以多个物理单元的组合实现。此外，为了突出本发明的创新部分，本实施方式中并没有将与解决本发明所提出的技术问题关系不太密切的单元引入，但这并不表明本实施方式中不存在其它的单元。
本发明第四实施方式涉及一种视频的多点同屏播放系统。第四实施方式在第三实施方式的基础上加以改进，主要改进之处在于：在本发明第四实施方式中，划分模块将显示屏划分成与终端数目相等的显示区域。其中，显示区域的大小可调节；并且，处于用户正对方向的显示区域的尺寸大于其余方向的显示区域的尺寸。
由于第二实施方式与本实施方式相互对应，因此本实施方式可与第二实施方式互相配合实施。第二实施方式中提到的相关技术细节在本实施方式中依然有效，在第二实施方式中所能达到的技术效果在本实施方式中也同样可以实现，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第二实施方式中。
结合本文中所揭示的实施例而描述的方法或算法的步骤可直接体现于硬件中，由处理器执行的软件模块中或所述两者的组合中。软件模块可驻留在随机存取存储器(RAM)、快闪存储器、只读存储器(ROM)、可编程只读存储器(PROM)，可擦除只读存储器(PROM)、可擦除可编程只读存储器(EPROM)、电可擦除可编程只读存储器(EEPROM)、寄存器、硬盘、可装卸式盘、压缩光盘只读存储器(CD-ROM)或此项技术中已知的任一其他形式的存储媒体。在替代方案中，存储媒体可与处理器成一体式。处理器及存储媒体可驻留在专用集成电路(ASIC)中。ASIC可驻留在计算装置或用户终端中，或者，处理器 及存储媒体可作为离散组件驻留在计算装置或用户终端中。
本领域的普通技术人员可以理解，上述各实施方式是实现本发明的具体实施例，而在实际应用中，可以在形式上和细节上对其作各种改变，而不偏离本发明的精神和范围。
