本公开实施例的其他特征和优点将在随后的具体实施方式部分予以详细说明
附图是用来提供对本公开实施例的进一步理解，并且构成说明书的一部分，与下面的具体实施方式一起用于解释本公开实施例，但并不构成对本公开实施例的限制。在附图中：

图5是根据本公开又一实施例的用于投影的方法的流程图。
图6是根据本公开一种实施例的用于投影的系统的示意框图。
图7是根据本公开又一实施例的用于投影的装置的示意框图。
以下结合附图对本公开实施例的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本公开实施例，并不用于限制本公开实施例。
根据本公开的第一实施例，提供一种用于投影的方法，该方法可以应用于需要进行投影的各种终端设备，这些终端设备可以是使用任何操作系统的终端设备，例如安卓系统、苹果系统、Windows系统中的任意一者。另外，这些终端设备也可以是各种类型的终端设备，例如，机器人、手机、平板电脑、便携式电脑、台式计算机等。另外，这些终端设备可以具有显示器，也可以不具有显示器。也就是说，本公开实施例对终端设备的类型不做限制。
如图1所示，根据该实施例的用于投影的方法可以包括以下步骤S101至S104，也即，在终端处：
在步骤S101中，在监测到需要进行投影后，建立无线接入点；
在步骤S102中，发送投影请求，所述投影请求包括用于请求投影设备接入的信息和所述无线接入点的接入认证信息；
在步骤S103中，在接收到投影设备发送的连接请求且所述连接请求包括所述接入认证信息时，建立所述投影设备与所述无线接入点的通信连接；
在步骤S104中，通过所建立的通信连接向所述投影设备传输要被投影的内容。
通过上述技术方案，由于投影设备与无线接入点之间的通信连接是通过终端发送包括无线接入点的接入认证信息的投影请求且然后在终端接收到投影设备发送的包括接入认证信息的连接请求时自动建立的，因此其不需要像现有技术那样人工手动连接投影设备，因此能够避免投影准备前的繁琐工作。
在一种可能的实施方式中，步骤S102中发送的投影请求中还可以包括所述终端设备的当前位置、投影设备解码能力要求、投影设备解密能力要求等信息，以便由符合要求的投影设备对终端设备发送的投影请求做出回应。
在一种可能的实施方式中，步骤S102中的所述发送投影请求可以包括：通过广播的方式发送所述投影请求。这样，需要进行投影的终端设备就能够
广播其投影需求，以便接收到投影需求的投影设备能够做出回应。
在一种可能的实施方式中，步骤S104中的所述通过所建立的通信连接向所述投影设备传输要被投影的内容，可以利用实时流传输协议来完成。这样，投影设备与终端设备之间通过点对点的方式进行通信，不仅有效保障了数据传输的安全性，还保障了流传输的低时延。
例如，终端设备可以启动实时流传输协议(Real Time Streaming Protocol，RTSP)流媒体服务，并将RTSP流媒体服务的访问地址经由所建立的通信连接发送给投影设备。然后，投影设备通过RTSP创建流媒体会话，向终端设备发送RTSP描述请求，在终端设备接收到RTSP描述请求之后，通过所建立的通信连接向投影设备发送要被投影的内容的编码算法、编码参数、实时流加密传输所使用的加密算法和解密密钥，其中解密算法及解密密钥可以通过RTSP携带的会话描述协议(Session Description Protocol，SDP)进行传递。然后，投影设备通过所建立的通信连接向终端设备发送RTSP建立请求，该RTSP建立请求包括实时流的传输方式和接收地址。然后，投影设备通过所建立的通信连接向终端设备发送RTSP播放请求，在终端设备接收到RTSP播放请求之后，通过所建立的通信连接向投影设备实时流加密传输要被投影的内容，其中可以通过安全实时传输协议(Secure Real Time Transport Protocol，SRTP)来加密传输要被投影的内容。
在一种可能的实施方式中，根据该实施例的方法还可以包括：通过所建立的通信连接接收投影设备发送的RTSP停止请求；在接收到所述RTSP停止请求之后，停止通过所建立的通信连接向投影设备实时流加密传输要被投影的内容。这样，在投影设备请求停止投影时，终端设备就能够及时地进行处理。
根据本公开的第二实施例，还提供一种用于投影的装置，该装置可以应
用于终端设备，其中已经在根据本公开的第一实施例中对终端设备进行了详细描述，此处不再赘述。如图2所示，该装置可以包括以下模块，也即，在终端处：
无线接入点建立模块201，用于在监测到需要进行投影后，建立无线接入点；
投影请求发送模块202，用于发送投影请求，所述投影请求包括用于请求投影设备接入的信息和所述无线接入点的接入认证信息；
通信连接建立模块203，用于在接收到投影设备发送的连接请求且所述连接请求包括所述接入认证信息时，建立所述投影设备与所述无线接入点的通信连接；
投影内容传输模块204，用于通过所建立的通信连接向所述投影设备传输要被投影的内容。
通过上述技术方案，由于投影设备与无线接入点之间的通信连接是通过投影请求发送模块202发送包括无线接入点的接入认证信息的投影请求且然后在通信连接建立模块203接收到投影设备发送的包括接入认证信息的连接请求时由通信连接建立模块203自动建立的，因此其不需要像现有技术那样人工手动连接投影设备，因此能够避免投影准备前的繁琐工作。
在一种可能的实施方式中，投影请求发送模块202发送的投影请求中还可以包括所述终端设备的当前位置、投影设备解码能力要求、投影设备解密能力要求等信息，以便由符合要求的投影设备对投影请求发送模块202发送的投影请求做出回应。
在一种可能的实施方式中，所述投影请求发送模块202可以通过广播的方式发送所述投影请求。这样，需要进行投影的终端设备就能够广播其投影需求，以便接收到投影需求的投影设备能够做出回应。
根据本公开第二实施例的用于投影的装置中各个模块做执行的操作的
具体实施方式已经在根据本公开第一实施例的用于投影的方法中进行了详细描述，此处不再赘述。
根据本公开的第三实施例，提供一种用于投影的方法，该方法可以应用于投影设备。如图3所示，根据该实施例的方法可以包括以下步骤S301至S303，也即，在投影设备处：
在步骤S301中，接收投影请求，所述投影请求包括用于请求投影设备接入的信息和无线接入点的接入认证信息；
在步骤S302中，向所述无线接入点发送连接请求，所述连接请求包括所述接入认证信息；
在步骤S303中，在基于所述连接请求建立与所述无线接入点的通信连接之后，通过所述通信连接接收要被投影的内容并进行投影。
通过上述技术方案，由于投影设备与无线接入点之间的通信连接是通过投影设备接收包括无线接入点的接入认证信息的投影请求且然后发送包括接入认证信息的连接请求时自动建立的，因此其不需要像现有技术那样人工手动连接投影设备，因此能够避免投影准备前的繁琐工作。
在一种可能的实施方式中，步骤S301中接收到的投影请求中还可以包括终端设备的当前位置、投影设备解码能力要求、投影设备解密能力要求等信息，这样接收到投影请求的投影设备就能够判断自己是否符合投影要求，并在符合投影要求时对接收到的投影请求做出回应。
在一种可能的实施方式中，所述投影请求通过广播的方式被所述无线接入点发送。这样，需要进行投影的终端设备就能够广播其投影需求，以便接收到投影需求的投影设备能够做出回应。
另外，投影设备如何通过所建立的通信连接接收要被投影的内容并进行投影已经在根据本公开的第一实施例中进行了详细描述，此处不再赘述。
根据本公开的第四实施例，提供一种用于投影的装置，该装置可以应用于投影设备，如图4所示，该装置可以包括：
投影请求接收模块401，用于接收投影请求，所述投影请求包括用于请求投影设备接入的信息和无线接入点的接入认证信息；
连接请求发送模块402，用于向所述无线接入点发送连接请求，所述连接请求包括所述接入认证信息；
投影模块403，用于在基于所述连接请求建立与所述无线接入点的通信连接之后，通过所述通信连接接收要被投影的内容并进行投影。
通过上述技术方案，由于投影设备与无线接入点之间的通信连接是通过投影请求接收模块401接收包括无线接入点的接入认证信息的投影请求且然后由连接请求发送模块402发送包括接入认证信息的连接请求而自动建立的，因此其不需要像现有技术那样人工手动连接投影设备，因此能够避免投影准备前的繁琐工作。
在一种可能的实施方式中，投影请求接收模块401接收到的投影请求中还可以包括终端设备的当前位置、投影设备解码能力要求、投影设备解密能力要求等信息，这样接收到投影请求的投影设备就能够判断自己是否符合投影要求，并在符合投影要求时对接收到的投影请求做出回应。
在一种可能的实施方式中，所述投影请求通过广播的方式被所述无线接入点发送。这样，需要进行投影的终端设备就能够广播其投影需求，以便接收到投影需求的投影设备能够做出回应。
另外，投影模块403如何通过所建立的通信连接接收要被投影的内容并进行投影已经在根据本公开的第一实施例中进行了详细描述，此处不再赘述。
根据本公开的第五实施例，提供一种用于投影的方法，该方法可以应用于包括终端设备、服务器和投影设备的系统，如图5所示，该方法可以包括
以下步骤S501至S505。
在步骤S501中，在终端处，在监测到需要进行投影之后建立无线接入点，并向服务器发送投影请求，所述投影请求包括用于请求投影设备接入的信息和所述无线接入点的接入认证信息；
在步骤S502中，在服务器处，接收所述投影请求，查找可用的投影设备并向查找到的可用投影设备转发所述投影请求；
在步骤S503中，在投影设备处，接收所述服务器转发的所述投影请求，并向所述无线接入点发送连接请求，所述连接请求包括所述接入认证信息；
在步骤S504中，在所述终端处，在接收到所述投影设备发送的连接请求且所述连接请求包括所述接入认证信息时，建立所述投影设备与所述无线接入点的通信连接，并通过所建立的通信连接向所述投影设备传输要被投影的内容；
在步骤S505中，在所述投影设备处，在基于所述连接请求建立与所述无线接入点的通信连接之后，通过所述通信连接接收要被投影的内容并进行投影。
通过上述技术方案，由于投影设备与作为无线接入点的终端设备之间的通信连接可以借助作为中继的服务器来完成，因此其不需要像现有技术那样人工手动连接投影设备，因此能够避免投影准备前的繁琐工作。
在一种可能的实施方式中，步骤S501中发送的投影请求中还可以包括终端设备的当前位置、投影设备解码能力要求、投影设备解密能力要求等信息，这样服务器在接收到投影请求之后就能够为终端设备查找到符合其投影要求的投影设备，并然后将投影请求转发给查找到的投影设备，这样查找到的投影设备就能够利用接收到的投影请求中包括的接入认证信息来请求与终端设备建立通信连接。
另外，云服务器可以通过基于虚拟专用网络(Virtual Private Network，
VPN)技术实现的安全专用网络来与终端设备和投影设备保持通信，以掌握终端设备和投影设备的信息，例如终端设备的当前位置、终端设备的投影请求、终端设备的投影要求(例如投影设备的解码能力、解密能力等要求)、投影设备的当前状态(空闲还是投影使用中)、投影设备的投影能力(例如，解码能力、解密能力、支持的音视频格式等)。这样，在终端设备有投影需求时，服务器就能够为终端设备查找到符合其投影需求的投影设备，而且能够有效保证不执行公共网络上的未经认证的控制指令。当然，除了安全专用网络，服务器还可以通过例如GSM、CDMA、LTE等的无线通信网络与终端设备、投影设备进行通信。
另外，由于服务器处有可能会同时接收到多个终端设备的投影请求，因此服务器可以对接收到的多个投影请求通过内部消息队列或内部接口的形式进行处理，以及通过内部消息队列或内部接口的形式向符合要求的投影设备转发投影请求，这样就能够平缓服务器的实时压力。
在一种可能的实施方式中，根据该实施例的方法还可以包括：在所述终端处，向所述服务器发送验证码；在所述服务器处，将所述验证码转发给查找到的可用投影设备；在所述投影设备处，接收所述服务器转发的所述验证码并发出包括所述验证码的信息；在所述终端处，捕获所述包括所述验证码的信息，以确认存在可用的投影设备用于投影。这样，终端设备就能够有效地确认是否存在可用的投影设备用于投影。如果这些步骤是发生在在终端设备处建立无线接入点之前，那么终端设备就可以仅在确认有可用投影设备的情况下才建立无线接入点，从而提高终端设备的效率。
另外，上面所述的验证码可以包括各种形式，例如二维码、条形码、语音、文本等。
另外，投影设备处发出的包括所述验证码的信息可用为包括所述验证码的屏幕显示信息(在这种情况下，终端设备可以通过视觉识别技术来识别屏
幕显示信息)、包括所述验证码的无线电信息(在这种情况下，终端设备可以通过接收无线电信息并进行匹配的方式来验证是否存在可用投影设备)和包括所述验证码的语音信息(在这种情况下，终端设备可以通过语音识别技术来识别投影设备发出的语音信息中是否包括其发送的验证码)中的一者。
在一种可能的实施方式中，在终端设备处希望结束投影时，可以通过终端设备与服务器之间的安全专用网络向服务器发送投影结束请求，然后服务器将该投影结束请求转发给投影设备，然后投影设备在接收到投影结束请求之后就能够结束投影、断开与终端设备的通信连接并返回到投影前的界面或者屏幕主界面。另外，由于媒体流和控制信令通常是分开的，所以诸如投影请求、投影结束请求之类的控制信令是通过服务器在终端设备和投影设备之间转发的，而关于要被投影的内容的媒体流则是通过终端设备与投影设备之间的通信连接传输的，这样能够提高投影的效率。
根据本公开的第六实施例，提高一种用于投影的系统，如图6所示，该系统可以包括：
终端处模块601，用于在所述终端处监测到需要进行投影之后建立无线接入点，并向服务器发送投影请求，所述投影请求包括用于请求投影设备接入的信息和所述无线接入点的接入认证信息；
服务器处模块602，用于接收所述投影请求，查找可用的投影设备并向查找到的可用投影设备转发所述投影请求；

所述投影设备处模块603，还用于在基于所述连接请求建立与所述无线接入点的通信连接之后，通过所述通信连接接收要被投影的内容并进行投影。
通过上述技术方案，由于投影设备与作为无线接入点的终端设备之间的通信连接可以借助作为中继的服务器来完成，因此其不需要像现有技术那样人工手动连接投影设备，因此能够避免投影准备前的繁琐工作。
在一种可能的实施方式中，终端处模块601发送的投影请求中还可以包括终端设备的当前位置、投影设备解码能力要求、投影设备解密能力要求等信息，这样服务器处模块602在接收到投影请求之后就能够为终端设备查找到符合其投影要求的投影设备，并然后将投影请求转发给查找到的投影设备，这样查找到的投影设备就能够利用接收到的投影请求中包括的接入认证信息来请求与终端设备建立通信连接。
另外，服务器处模块602可以通过基于虚拟专用网络(Virtual Private Network，VPN)技术实现的安全专用网络来与终端处模块601和投影设备处模块603保持通信，以掌握终端设备和投影设备的信息，例如终端设备的当前位置、终端设备的投影请求、终端设备的投影要求(例如投影设备的解码能力、解密能力等要求)、投影设备的当前状态(空闲还是投影使用中)、投影设备的投影能力(例如，解码能力、解密能力、支持的音视频格式等)。这样，在终端设备有投影需求时，服务器处模块602就能够为终端设备查找到符合其投影需求的投影设备，而且能够有效保证不执行公共网络上的未经认证的控制指令。当然，除了安全专用网络，服务器处模块602还可以通过例如GSM、CDMA、LTE等的无线通信网络与终端处模块601、投影设备处模块603进行通信。
另外，由于服务器处模块602处有可能会同时接收到多个终端处模块
601的投影请求，因此服务器处模块602可以对接收到的多个投影请求通过内部消息队列或内部接口的形式进行处理，以及通过内部消息队列或内部接口的形式向符合要求的投影设备转发投影请求，这样就能够平缓服务器处模块602的实时压力。
在一种可能的实施方式中，所述终端处模块601，还用于向所述服务器处模块602发送验证码；所述服务器处模块602，还用于将所述验证码转发给查找到的可用投影设备；所述投影设备处模块603，还用于接收所述服务器处模块602转发的所述验证码并发出包括所述验证码的信息；所述终端处模块601，还用于捕获所述包括所述验证码的信息，以确认存在可用的投影设备用于投影。这样，终端设备就能够有效地确认是否存在可用的投影设备用于投影。如果这些操作是发生在在终端设备处建立无线接入点之前，那么终端设备就可以仅在确认有可用投影设备的情况下才建立无线接入点，从而提高终端设备的效率。
另外，上面所述的验证码可以包括各种形式，例如二维码、条形码、语音、文本等。
另外，投影设备处模块603发出的包括所述验证码的信息可用为包括所述验证码的屏幕显示信息(在这种情况下，终端设备可以通过视觉识别技术来识别屏幕显示信息)、包括所述验证码的无线电信息(在这种情况下，终端设备可以通过接收无线电信息并进行匹配的方式来验证是否存在可用投影设备)和包括所述验证码的语音信息(在这种情况下，终端设备可以通过语音识别技术来识别投影设备发出的语音信息中是否包括其发送的验证码)中的一者。
在一种可能的实施方式中，在终端设备处希望结束投影时，可以通过终端处模块601与服务器处模块602之间的安全专用网络向服务器处模块602发送投影结束请求，然后服务器处模块602将该投影结束请求转发给投影设
备处模块603，然后投影设备处模块603在接收到投影结束请求之后就能够结束投影、断开与终端处模块601的通信连接并返回到投影前的界面或者屏幕主界面。另外，由于媒体流和控制信令通常是分开的，所以诸如投影请求、投影结束请求之类的控制信令是通过服务器处模块602在终端处模块601和投影设备处模块603之间转发的，而关于要被投影的内容的媒体流则是通过终端处模块601与投影设备处模块603之间的通信连接传输的，这样能够提高投影的效率。
