Description

应用于无网络环境的健身视频流获取方法及系统
本申请要求于2021年12月08日提交中国专利局、申请号为202111487674.5、名称为“应用于无网络环境的健身视频流获取方法及系统”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
本申请涉及通信技术领域，具体涉及应用于无网络环境的健身视频流获取方法及系统。
背景技术
基于超文本传输协议直播流(Hyper Text Transfer Protocol Live Streaming，HLS)是苹果公司提出的基于超文本传输传输协议(Hyper Text Transfer Protocol，HTTP)的流媒体网络传输协议。类似于运动图像专家组-基于HTTP的动态自适应流(Moving Picture Experts Group-Dynamic Adaptive Streaming over HTTP，MPEG-DASH)，但是HLS更加简洁，它的基本原理也是服务端把文件或媒体流按照不同的码率切分成一个个小片段进行传输，客户端在播放码流时，可以根据自身的带宽及性能限制，在同一视频内容的不同码率的备用源中，选择合适码率的码流进行下载播放。在传输会话开始时，客户端首先需要下载描述不同码流元数据的M3U8索引文件。
目前HLS技术已经广泛的应用在需要视频传输的领域中，健身镜的视频传输也常采用HLS技术。然而HLS技术依赖于健身镜与流媒体服务器的数据交互，如果健身镜与流媒体服务器的连接中断，会造成健身镜上健身视频中断，影响用户健身体验。

结合参阅图1，为本申请实施例所提供的应用于无网络环境的健身视频流获取方法的流程示意图，应用于无网络环境的健身视频流获取方法可以应用于图1中的应用于无网络环境的健身视频流获取系统，其中应用于无网络环境的健身视频流获取系统包括带有镜面显示器的健身镜。应用于无网络环境的健身视频流获取方法具体可以包括以下步骤S1-步骤S3所描述的内容。
S1：当健身镜与流媒体服务器的连接断开时，健身镜向用户电子设备发送数据桥接请求。
S2：用户电子设备收到数据桥接请求后，向API服务器发送健身视频流播放请求，并接收API服务器根据健身视频流播放请求生成的视频流切片地址。
S3：用户电子设备根据视频流切片地址从流媒体服务器下载视频流切片，并将下载视频流切片发送至健身镜；健身镜通过镜面显示器展示视频流切片。
本实施例实施时，健身镜采用HLS技术从流媒体服务器上下载健身视频，并通过镜面显示器展示该健身视频，健身镜一般通过接收API服务器发送的视频切片地址从流媒体服务器上下载健身视频，如果健身镜失去与流媒体服务器的连接，说明当前健身镜失去了获取视频切片的途径，此时向用户电子设备发送数据桥接请求。
在采用HLS技术进行视频播放时，视频一般会额外缓存一小段时间，或者是缓存一个整段的视频，在本实施例中，利用这一小段视频播放的时间，及时通知用户电子设备，利用用户电子设备，如手机、平板等设备，实现视频流切片的无线下载，并通过近场通信如蓝牙等方式发送至健身镜， 从而保证了在健身镜断网的情况下，可以无间断的对健身视频进行持续的播放。
在一些实施例中，由API服务器提供视频切片对应的地址。示例的，用户电子设备与API服务器的数据交互通过HTTPS协议实现，可以提高数据传输的安全性，而用户电子设备与健身镜的数据交互采用近场蓝牙通信的方式。API服务器上预存的切片地址索引为URL与视频切片的对应关系，API服务器搜索到的URL地址通过HTTPS协议发送至健身镜或用户电子设备，健身镜或用户电子设备根据URL地址从流媒体服务器下载相应的切片。本实施例中，健身镜断网期间及时通过用户电子设备进行视频流切片的下载和转发，保证了在各种情况下，健身镜的健身视频都可以持续不间断的播放，提高了用户体验。
在一些实施例中，数据桥接请求包括第一视频流切片标识和第二视频流切片标识；第一视频流切片标识为健身镜当前播放的健身视频中未下载完成的视频流切片的标识；第二视频流切片标识为健身镜播放列表中未播放的健身视频的视频流切片的标识。
用户电子设备收到数据桥接请求后，向API服务器发送健身视频流播放请求，并接收API服务器根据健身视频流播放请求生成的视频流切片地址包括如下内容。
用户电子设备收到数据桥接请求后，从数据桥接请求中提取第一视频流切片标识和第二视频流切片标识，并根据第一视频流切片标识和第二视频流切片标识生成健身视频流播放请求；用户电子设备将健身视频流播放请求发送至API服务器。
API服务器生成对应第一视频流切片标识和第二视频流切片标识的视频流切片地址，并将视频流切片地址发送至用户电子设备。
本实施例实施时，数据桥接请求还包括用于向API服务器发送健身视频流播放请求的标识，其中，第一视频流切片标识是当前视频所缺少的视 频流切片对应标识，而第二视频流标识是播放列表中其他视频的标识。应当理解的是，用户电子设备在收到API服务器发送的视频切片流地址时，应当按照HLS对应的规则进行视频流切片的下载，即从第一视频流标识开始下载并播放。
在一些实施例中，当健身镜与流媒体服务器的连接断开时，健身镜向用户电子设备发送数据桥接请求包括：
健身镜与流媒体服务器的连接断开时，判断用户电子设备是否与健身镜处于同一个局域网络中；如果用户电子设备与健身镜处于同一个局域网络中，则健身镜向用户电子设备发送第一数据桥接请求；用户电子设备收到第一数据桥接请求时断开局域网连接，通过无线通信网络建立与API服务器的连接，并通过近场通信网络建立与健身镜的连接。
本实施例实施时，很多时候在健身的过程之中，用户的终端设备经常会和健身镜处在同一个局域网中，用户的终端设备通过无线保真(Wireless Fidelity，WIFI)接入该局域网，而健身镜发生与视频流服务器的连接断开，往往是因为该局域网失去了外网连接。所以在本实施例中，第一数据桥接请求还用于通知用户电子设备断开局域网、通过无线通信网络如通用无线分组业务(General Packet Radio Service，GPRS)、第四代(Fourth Generation，4G)网络等建立和API服务器的通信，并建立与健身镜的近场通信。应当理解的是，在第一数据桥接请求中，还可以包括健身镜给予用户电子设备的连接API服务器的授权许可，以及近场通信配对码。
在一些实施例中，应用于无网络环境的健身视频流获取方法还可以包括：
当用户电子设备通过近场通信网络建立与健身镜的连接时，获取近场通信网络的通信速率；用户电子设备根据通信速率生成对应的视频切片分辨率数据，并将视频切片分辨率数据写入健身视频流播放请求；API服务器从健身视频流播放请求中提取视频切片分辨率数据和健身视频标识，并 生成对应视频切片分辨率数据和健身视频标识的视频流切片地址。
本实施例实施时，一般的近场通信网络的通信速率往往不高，如果采用原分辨率的视频切片数据进行传输，很容易造成健身镜的视频播放卡顿，所以在本实施例中，采用了获取近场通信网络的通信速率，并进行对应分辨率的视频切片的下载，有效缓解传输码率带来的视频卡顿。
在一些实施例中，生成对应视频切片分辨率数据和健身视频标识的视频流切片地址包括：
API服务器根据视频切片分辨率数据和健身视频标识从配置于API服务器的视频流切片索引中检索出对应的视频流切片地址。
请参阅图2，基于相同的发明构思，本实施例提供了应用于无网络环境的健身视频流获取系统，包括带有镜面显示器的健身镜。

用户电子设备用于收到数据桥接请求后，向API服务器发送健身视频流播放请求，并接收API服务器根据健身视频流播放请求生成的视频流切片地址；根据视频流切片地址从流媒体服务器下载视频流切片，并将下载视频流切片发送至健身镜。
健身镜还用于通过镜面显示器展示视频流切片。
在一些实施例中，数据桥接请求包括第一视频流切片标识和第二视频流切片标识；第一视频流切片标识为健身镜当前播放的健身视频中未下载完成的视频流切片的标识；第二视频流切片标识为健身镜播放列表中未播放的健身视频的视频流切片的标识。
用户电子设备还用于收到数据桥接请求后，从数据桥接请求中提取第一视频流切片标识和第二视频流切片标识，并根据第一视频流切片标识和第二视频流切片标识生成健身视频流播放请求；将健身视频流播放请求发送至API服务器。
