Description

控制终端和资源共享的方法 技术领域
本发明涉及资源共享技术领域， 具体而言， 涉及控制终端和资源共享 的方法。 背景技术
在多台终端之间， 有时需要进行播放内容的共享， 比如将一台终端上 播放的视频、 音频等在其他终端上进行播放。 在现有技术方案下， 实现播 放内容的共享时， 对于任何内容都是直接将一台终端上播放的画面、 声音 等进行镜像编码发送， 而其他终端得到数据后进行解码并显示于屏幕上。
在上述方式下， 由于屏幕内容共享过程中画面内容会不断更改， 而为 了保持实时性， 对传输过程中画面的延时要求非常高， 要求小于 100 毫 秒， 那么为了满足相应的帧率， 对无线网络环境要求很高， 在无线网络较 差的环境下， 屏幕共享过程中甚至会出现掉帧、 失真以及同步延时； 且受 限于无限网络带宽， 屏幕内容共享过程中无可避免会采用压缩算法， 会导 致在播放视频等媒体内容时会降低其清晰度导致体验降低。 同时， 在需要 实时进行视频编解码的情况下， 上述技术方案对资源的发送端在数据处理 等方面的要求也很高。 最后， 由于接收端与发送端屏幕尺寸以及分辨率的 差异性， 现有技术方案中， 传输适配的是发送端分辨率， 可能无法完全适 应接收端的屏幕分辨率， 导致资源播放效果受到影响。
因此， 需要一种新的资源共享技术， 可以使得在控制终端和受控终端 之间进行多媒体资源共享时， 无需直接传送播放画面数据， 节省带宽资 源， 降低对控制终端的要求。 发明内容
本发明正是基于上述问题， 提出了一种新的资源共享技术， 可以使得 在控制终端和受控终端之间进行多媒体资源共享时， 无需直接传送播放画 面数据， 节省带宽资源， 降低对控制终端的要求。

在该技术方案中， 多媒体资源可以包括音频、 图片和 /或视频等。 通 过将地址信息发送至受控终端， 使得无需控制终端将多媒体资源的数据进 行编码发送， 尤其是当该多媒体资源为实时资源时， 降低了对于控制终端 自身的硬件要求。 同时， 由于受控终端可以根据地址信息自行下载相应的 数据， 实现对多媒体资源的播放， 而无需在控制终端和受控终端之间直接 进行传输， 从而降低了两者之前的网络环境要求， 尤其是当任一方处于无 线网络环境下时， 有利于提升对多媒体资源的共享效果。 此外， 由于受控 终端获取的多媒体资源不是由控制终端进行编码发送的， 因而便于实现受 控终端根据自身的分辨率等信息进行解码， 从而得到更好的播放效果。 在上述技术方案中， 优选地， 所述地址信息包括： 网络资源的网络链 接地址、 本地文件资源在所述控制终端中的存储路径或用于获取所述控制 终端实时采集的多媒体数据的数据传输端口。
在该技术方案中， 由于受控终端可以直接根据地址信息获取对应的多 媒体资源， 而无需控制终端进行编码发送， 因而降低了对于控制终端的硬 件等方面的要求。 而尤其是对于通过网络链接地址进行数据获取的方式， 仅对受控终端自身的网络环境存在要求， 而降低了对于控制终端与受控终 端之间的网络环境要求。 实时采集的多媒体资源包括如通过摄像头实时拍 摄的照片或视频， 或是通过话筒实时采集的声音等， 或是抓取的控制终端 的屏幕画面等。

在该技术方案中， 受控终端生成控制界面， 控制终端通过将控制信息 发送给受控终端， 使得控制终端可以控制多媒体资源在受控终端上的播放 过程。 由于不需要进行画面等数据的实时传输， 仅通过传输数据量明显更 小的控制信息， 因而有利于降低对于网络环境的需求。
在上述技术方案中， 优选地， 在播放所述多媒体资源之前， 还包括： 按照预设的屏幕参数对获取的所述多媒体资源进行解码。
在该技术方案中， 屏幕参数包括如分辨率等信息， 若由控制终端直接 将多媒体资源进行编码发送时， 对于播放的画面等是根据控制终端的屏幕 参数进行编码的， 可能并不能够适用于受控终端， 因此， 通过由受控终端 直接获取多媒体资源并进行直接解码， 可以按照自身的屏幕参数进行解 码， 从而对于任意屏幕参数下的受控终端都具有 ^艮好的自适应性。
根据本发明的又一方面， 还提出了一种系统， 包括如上述任一技术方 案所述的控制终端， 以及如上述任一技术方案所述的受控终端。
在该技术方案中， 多媒体资源可以包括音频、 图片和 /或视频等。 通 过将地址信息发送至受控终端， 使得无需控制终端将多媒体资源的数据进 行编码发送， 尤其是当该多媒体资源为实时资源时， 降低了对于控制终端 自身的硬件要求。 同时， 由于受控终端可以根据地址信息自行下载相应的 数据， 实现对多媒体资源的播放， 而无需在控制终端和受控终端之间直接 进行传输， 从而降低了两者之前的网络环境要求， 尤其是当任一方处于无 线网络环境下时， 有利于提升对多媒体资源的共享效果。 此外， 由于受控 终端获取的多媒体资源不是由控制终端进行编码发送的， 因而便于实现受 控终端根据自身的分辨率等信息进行解码， 从而得到更好的播放效果。
通过以上技术方案， 可以使得在控制终端和受控终端之间进行多媒体 资源共享时， 无需直接传送播放画面数据， 节省带宽资源， 降低对控制终 端的要求。 附图说明

图 6示出了根据本发明的一个实施例的在多终端之间实现多媒体资源 共享的具体流程图。
假定在多个终端之间进行多媒体资源的共享， 则对于其中的一组终端 而言， 如图 6所示， 这组终端实现多媒体资源共享的具体流程包括：
步骤 601 , 发送端判断自身当前是否在播放多媒体资源， 这里的多媒 体资源可以包括如视频、 音频、 图片等各种形式的资源。 若是， 则进入步 骤 602 , 否则进入步骤 625。 通过对 "当前是否播放多媒体资源" 这一应 用场景的判断， 从而实现对不同场景下采用不同的方案流程。
步骤 602 , 发送端判断当前播放的多媒体资源是否为实时资源， 若 是， 则进入步骤 616 , 否则进入步骤 604。 发送端在播放该多媒体资源 时， 可以在自身的屏幕上进行相应的显示画面， 包括效果画面 （视频帧或 图片本身） 或控制画面等， 也可以不进行显示， 仅发出声音等， 则此时可 以通过物理按键等进行控制。
步骤 604, 判断发送端播放的多媒体资源是否为网络资源， 若是， 则 进入步骤 606 , 否则进入步骤 612。
步骤 606 , 若为网络资源， 比如是在线播放的一个网络视频或一张图 片， 则发送端对该网络资源进行解析， 以获取其对应的网络链接地址。
步骤 608 , 发送端将解析得到的网络链接地址发送至接收端。 由于是 网络资源， 使得无需在发送端和接收端之间建立网络建立， 接收端可以直 接从网络侧获取对应的多媒体资源以用于播放， 因而降低了在发送端与接 收端之间的网络环境要求。
步骤 610, 接收端获取多媒体资源。 具体地， 若由步骤 608进入步骤 610 , 则是根据接收到的网络链接地址获取相应的多媒体资源， 若由步骤 614或步骤 618 进入步骤 610, 则利用对应的地址信息获取相应的多媒体 资源， 下面将在步骤 614和步骤 618中具体说明。
步骤 612 , 若为本地资源， 比如发送端正在播放本地的视频、 音频或 图片等文件， 则由发送端获取这些本地资源的存储路径。
步骤 614 , 发送端将存储路径发送至接收端， 并进入步骤 610 , 使得 接收端可以根据该存储路径， 从而连接至发送端， 并直接从该存储路径获 取相应的本地资源。
步骤 616 , 若多媒体资源为实时资源， 比如发送端通过摄像头实时拍 摄的照片或视频， 或是通过话筒实时采集的声音等， 或是抓取的控制终端 的屏幕画面等， 则发送端获取实时采集的多媒体数据。
步骤 618 , 发送端解析自身的数据传输端口。
步骤 619 , 发送端将数据传输端口发送至接收端， 从而进入步骤 610 之后， 接收端可以根据接收到的数据传输端口访问发送端， 以获取发送端 实时采集的多媒体数据。
步骤 620 , 接收端在获取多媒体资源之后， 将根据自身的屏幕参数进 行解码。 由于不是由发送端对多媒体资源进行编码后传输给接收端， 而是 由接收端主动获取了多媒体资源， 因而接收端可以根据自身的屏幕参数， 比如分辨率等， 对获取的多媒体资源进行解码， 以使得解码后的数据能够 适应于接收端的屏幕， 从而得到最佳的显示效果。
步骤 622 , 接收端利用解码得到的数据进行播放。
步骤 624, 发送端对接收端进行播放控制。 具体地， 由于在发送端和 接收端之间都在对相同的多媒体资源进行播放， 因而发送端可以在自身的 屏幕界面上进行播放控制， 比如拖动播放进度、 暂停、 快进、 下一张图片 等， 则发送端在检测到控制操作后， 可以将对应的控制信息发送至接收 端， 则接收端可以根据接收到的控制信息， 执行对应的播放控制。
步骤 625 , 在发送端不在播放多媒体资源的情况下， 由于不存在对应 的地址信息， 因而直接抓取发送端的屏幕画面内容。
步骤 626 , 将抓取到的屏幕画面内容进行编码并压缩传输至接收端， 以供接收端对接收到的数据进行解码后， 得到发送端的屏幕画面内容。 通 过步骤 601、 步骤 625和步骤 626的步骤流程， 结合其他步骤流程， 从而 无论发送端当前是否播放多媒体资源或处于其他任意界面下， 都能够实现 发送端对接收端的屏幕共享。
通过上述技术方案， 尤其是在同步播放网络资源的情况下， 由于发送 端仅需要将控制信息发送至接收端， 即可实现在两者之间的资源同步播放 和控制， 传输数据量大幅度削减， 带宽消耗变小， 可提供更小的数据延时 以及较差的无线网络环境更好的适应能力。
需要说明的是， 本发明中虽然没有提及控制终端和受控终端的数量， 但实际上本发明的技术方案适用于一对一、 一对多、 多对一、 多对多等多 种情况， 因为无论数量多少， 对于任意一台控制终端与相应的受控终端而 言， 其控制过程实际上是相同的。
以上结合附图详细说明了本发明的技术方案， 考虑到相关技术中， 在 终端之间进行多媒体资源的播放共享时， 需要由控制终端直接将数据编码 发送至受控终端， 对于控制终端和网络环境的要求较高， 因此， 本发明提 供了控制终端、 受控终端、 资源共享的方法和系统， 可以使得在控制终端 和受控终端之间进行多媒体资源共享时， 无需直接传送播放画面数据， 节 省带宽资源， 降低对控制终端的要求。
以上所述仅为本发明的优选实施例而已， 并不用于限制本发明， 对于 本领域的技术人员来说， 本发明可以有各种更改和变化。 凡在本发明的精 神和原则之内， 所作的任何修改、 等同替换、 改进等， 均应包含在本发明 的保护范围之内。
