实施例一
参照图1，示出了本申请的一种数据传输方法实施例的步骤流程图，具体可以包括如下步骤：
步骤102，服务提供设备在与客户端建立连接后生成虚拟输入设备。
本实施例采用服务提供设备和客户端为智能电视终端提供网络数据服务，其中，服务提供设备也称云终端，是设置在网络侧的硬件终端，由服务提供设备提供网络服务所需的各种数据，客户端的一种呈现形式可以是安装于智能电视终端的APP(应用程序，Application)，客户端对网络提供的数据进行解码并显示。其中，每个服务提供设备和客户端可以不具有唯一的对应关系，而是在客户端请求由服务提供设备提供网络服务器时为客户端临时分配一个服务提供设备，在分配后服务提供设备与客户端建立连接后，在连接期间服务提供设备为该客户端提供数据服务。其中，客户端和服务提供设备可以建立加密连接，例如通过SSL(Secure Sockets Layer，安全套接层)方式建立加密连接，从而通过两者之间的加密通道传输数据，保证数据传输的安全性。
本实施例中，在服务提供设备侧存储用户界面(User Interface，UI)的缓存数据，为该客户端提供相应的UI界面以显示。服务提供设备从帧缓冲设备(Frame Buffer)中获取UI缓存，然后对UI缓存按照预置的编码格式进行编码，得到编码后的UI缓存，如采用h.264编码。再采用所述编码后的UI缓存通过实时流传输协议(Real Time Streaming Protocol，RTSP)采用流化方式生成TS流，将TS流推送给客户端以在所述客户端显示相应的用户界面。
本申请实施例中，客户端侧所显示的用户界面是能够为用户各种网络服务，例如在用户界面上可以包括各种菜单选项或图标等服务功能，例如包括：高清视频，超清电视、软件下载、游戏、生活服务(如缴费、购物等)等，从而通过该客户端用户可在电视上免费观看高清电影电视、玩体感游戏、热门大型3D游戏、网络购物、支付水电煤费用等等功能。在用户选择某一功能的图标或菜单后，可以继续进入相应的UI界面执行操作，例如播放高清视频时可以选择本地或网络资源等。
针对客户端所显示的UI界面，用户可以通过遥控器的外置设备进行控制，如选择某个功能，进入下一级界面等，而由于UI界面是基于服务提供设备的传送流解析显示的，因此对UI界面的控制响应也由服务提供设备执行。本实施例中服务提供设备在与客户端建立连接后，预先在用户空间虚拟一输入设备，通过该虚拟输入设备模拟硬件输入信号，在系统注入用户的输入信号对应输入事件并进行分发，从而实现服务提供设备对用户控制的响应。
步骤104，接收所述客户端发送的输入信号。
服务提供设备接收客户端发送的输入信号，该输入信号包括用户对服务提供设备显示的UI界面控制对应的信号。
步骤106，将输入信号写入所述虚拟输入设备，由所述虚拟输入设备对所述输入信号对应输入事件进行分发以响应所述输入信号。
将输入信号写入所述虚拟输入设备确定对应的输入事件，而后通过虚拟输入设备对输入信号对应输入事件进行分发，例如将输入事件分发给系统或应用等进行处理，从而对输入信号进行响应，如获取相应的UI缓存编码生成TS流反馈给客户端，实现对用户控制的云端响应。
步骤108，将响应于所述输入信号的响应信息反馈给所述客户端。
对输入信号进行响应生成对应的响应信息，然后将响应信息反馈给客户端，以使客户端对响应信息进行对应的处理如显示等。
综上所述，服务提供设备在与客户端建立加密连接以进行数据传输，而后生成虚拟输入设备以模拟各种硬件的输入信号，可扩展性较高，此后服务提供设备在接收客户端发送的输入信号，将输入信号写入所述虚拟输入设备，由所述虚拟输入设备对所述输入信号对应输入事件进行分发以响应所述输入信号并将响应信息反馈给客户端，可扩展性较高，处理过程比较简单，实现快速的对用户控制的云端响应。
上述论述了数据传输过程中服务提供设备对用户控制的响应处理，下面论述客户端侧的输入信号的传输控制步骤。
参照图2，示出了本申请的另一种数据传输方法实施例的步骤流程图，具体可以包括如下步骤：
步骤202，客户端在启动后与服务提供设备建立连接。
客户端在启动后可以向系统请求分配服务提供设备，在确定分配的服务提供设备后可以与服务提供设备建立连接。
在客户端与服务提供设备连接后由服务提供设备提供数据以在客户端侧显示相应的UI界面，因此服务提供设备会将用户界面缓存进行编码后生成传送流(Transport Stream，TS)发送给客户端，客户端在接收到传送流后会对该传送流进行解析而后生成相应的解析数据，对解析数据进行显示从而显示相应的用户界面。其中，服务提供设备中存储的UI缓存包括在客户端上显示的各种内容，如主UI界面，UI界面中所显示的各种APP、以及APP开启后相应的UI界面等，即客户端本地显示但并不存储主UI界面，也不存储 安装的APP等内容。
步骤204，接收原始信号，依据原始信号确定输入信号。
针对客户端所显示的UI界面，用户可以通过遥控器的外置设备进行控制，如选择某个功能，进入下一级界面等，而由于UI界面是基于服务提供设备的传送流解析显示的，因此对UI界面的控制响应也由服务提供设备执行。
因此客户端可以接收用户通过外置设备发送的原始信号，如包括用于控制UI界面变化的信号，又如包括用于控制播放切换的控制信号等。客户端依据该原始信号确定对应的输入信号。
步骤206，将输入信号发送给所述服务提供设备，以使服务提供设备对所述输入信息进行响应。
将该输入信号发送给服务提供设备，使得服务提供设备对该输入信号进行响应，生成相应的响应信息，例如生成响应于该输入信号的UI对应TS流反馈给客户端。
步骤208，接收所述服务提供设备反馈的响应信息，并对所述响应信息进行显示处理。
接收服务提供设备反馈的响应信息，然后对该响应信息进行显示处理，如该响应信息为TS流，则显示相应的UI界面。
综上所述，服务提供设备在与客户端建立连接以进行数据传输，客户端对接收的原始信号进行处理得到输入信号发送给服务提供设备，使服务提供设备对该输入信息进行响应从而客户端对响应信息进行显示处理，实现快速的对用户控制的云端响应。
实施例二
在上述实施例的基础上，本实施例继续论述服务提供设备和客户端之间的数据传输方法。
参照图3，示出了本申请的一种服务提供设备侧的数据传输方法实施例的步骤流程图，具体可以包括如下步骤：
步骤302，服务提供设备在启动后对端口进行监听。
步骤304，从所述端口接收信号与所述客户端建立长连接。
步骤306，在所述长连接建立成功后，在用户空间内生成虚拟输入设备。
服务提供设备在启动后会启动SSL Socket Server监听指定端口，从该端口接收连接信号与该客户端建立长连接。在长连接建立成功后，服务提供设备在用户空间内生成虚拟输入设备。例如，采用Uinput虚拟一个输入设备/dev/input/Ali-vinput。
其中，SSL Socket Server为服务提供设备用来接收加密输入信号的服务器应用。Uinput是linux用来实现用户空间输入设备的内核接口，利用它可以在用户空间虚拟输入设备，向系统中注入输入事件。
本申请一个可选实施例中，所述在用户空间内生成虚拟输入设备，包括：启动输入设备；通过驱动设备向所述输入设备添加事件类型，写入所述虚拟输入设备的基本信息；依据所述输入设备在所述用户空间内生成虚拟输入设备。
首先启动输入设备Uinput，通过驱动设备向Uinput添加事件类型，如键盘事件、鼠标事件等，以及可接受的事件值等，再写入所述虚拟输入设备的基本信息，如设备名称等，然后依据所述输入设备在所述用户空间内生成虚拟输入设备。
例如，虚拟输入设备可以采用如下方法创建：以Android系统为例，使用open("/dev/uinput",O_WRONLY|O_NONBLOCK)打开/dev/uinput设备获取fd；再使用ioctl(fd,UI_SET_EVBIT,EV_XXX)添加事件类型，包括同步事件、键盘事件、鼠标事件、触摸事件等；注册可接受的事件的值，包括键盘的键值、鼠标和触摸事件的x和y坐标等；初始化uinput_user_dev类型的变量uidev，该变量中保存待虚拟的设备的基本信息，包括设备名和总线类型等；使用write(fd,&uidev,sizeof(uidev))将待虚拟的设备信息写入/dev/uinput设备；使用ioctl(fd,UI_DEV_CREATE)生成虚拟设备。
其中，fd是指文件描述符，获取设备的文件描述符才能操作设备，本实施例中fd指向/dev/uinput设备。ioctl是设备驱动程序中对设备的输入输出通道进行管理的函数，参数&uidev为命令名，sizeof(uidev)为命令所需参数，实际处理中可以sizeof(uidev)设置该参数，也可以不设置该参数，通过该ioctl函数对fd所指向的设备执行UI_SET_EVBIT命令，EV_XXX是命令的参数，以此来添加事件类型。Write函数用来向fd所指向的设备写入数据，uidev为数据的首地址，sizeof(uidev)为数据大小。
步骤308，接收所述客户端发送的加密的输入信号，对所述加密的输入信号进行解密。
步骤310，将解密的输入信号写入所述虚拟输入设备。
步骤312，所述虚拟输入设备确定所述解密的输入信号对应的输入事件；
步骤314，将所述输入事件分发给上层应用或操作系统进行响应处理，生成对应的响应信息。
接收所述客户端发送的加密的输入信号，对所述加密的输入信号进行解密，然后将解密的输入信号写入虚拟输入设备。通过该虚拟输入设备确定所述解密的输入信号对应 的输入事件，并对输入事件进行分发，可以输入事件的类型、应用场景等信息将输入事件分发给上层应用或操作系统进行响应处理，生成对应的响应信息。
本申请一个可选实施例中，对所述加密的输入信号进行解密，包括：对所述加密的输入信号进行对称解密或非对称解密，获取解密的二进制输入信号或解密的键值信息。
接收所述客户端发送的加密的输入信号，对所述加密的输入信号进行解密，其中按照预置加解密方式，可以对该加密的输入信号进行对称解密或非对称解密，获取解密的二进制输入信号或解密的键值信息。
本实施例中，服务提供设备解密后得到的输入信号可以存在多种类型，如为指定系统的标准输入信号，又如为映射后的键值信息等，可以依据具体需求设定，或者依据需求对解密后的输入信号进行转换，得到所需的输入信息。
本申请另一个可选实施例中，对所述加密的输入信号进行解密之后，还包括：按照预置规则将所述解密的输入信号映射成相应的键值信息；所述虚拟输入设备确定所述解密的输入信号对应的输入事件，包括：所述虚拟输入设备查找所述键值信息对应的输入事件。
本实施例中，对于解密的输入信号还能是数字信息，此时可以将该数字信息预设的映射表将其映射成相应的键值信息，如按照预置协议将数字信息反Map成键值信息。当输入信号表现为键值信息的形式时，虚拟输入设备可以查找所述键值信息对应的输入事件，而后对输入事件进行分发。
其中一种虚拟输入设备对输入信号的处理过程如下：以android为例，可分为以下几步：
1、硬件抽象层(Hardware Abstraction Layer，HAL)的EventHub通过epoll机制监听/dev/input/目录下的所有设备文件描述符的变化，一旦有输入事件写入设备，EventHub就能读取到该事件；
2、Framework层的InputReader从EventHub读入原始输入事件后转化为android平台的输入事件，再将输入事件传递给InputDispatcher；
3、InputDispatcher根据输入事件以及场景的不同将事件分发给上层应用或系统，例如Home键和Power键会交由系统处理而不是上层应用，方向键等会交由应用处理。
从而通过虚拟输入设备模拟硬件输入的输入事件，对输入事件进行分发从而生成相应的响应信息。
本实施例中，由于客户端显示的UI界面是依据服务提供设备发送的TS流解析显示 的，因而用户对UI界面的控制，如选择某一功能，或者在其中安装APP等控制操作，看似是在客户端侧执行的，实际上均是将输入信息发送给服务提供设备，由服务提供设备执行相应的控制并反馈响应的TS流。
本申请一个可选实施例中，将所述输入事件分发给上层应用或操作系统进行响应处理，生成对应的响应信息，包括：将所述输入事件分发给上层应用或操作系统；所述上层应用或操作系统获取响应于所述输入事件的UI缓存；将所述UI缓存编码生成对应的TS流作为响应信息，以在所述客户端显示响应于输入信号的UI界面。
针对输入信号对应输入事件，虚拟输入设备会将该输入事件分发给对应的上层应用或操作系统，而后上层应用或操作系统获取响应于所述输入事件的UI缓存，例如输入事件为选择某一功能，则UI缓存可以为该功能对应的界面内容的缓存，又如输入事件为安装一APP，则在服务提供设备侧安装该APP，UI缓存为该APP安装完成对应的UI缓存。
步骤316，服务提供设备将响应信息反馈给客户端。
然后对该UI缓存进行编码以及流化处理生成TS流作为响应信息反馈给客户端。从而通过输入信号传输给服务提供设备，使得服务提供设备能够对该输入信号进行响应并反馈给客户端，从而实现对用户控制的云端响应。
上述论述了服务提供设备侧对用户控制的响应步骤，通过实施例继续论述对客户端侧的数据传输方法。
本申请一个可选实施例中，所述接收原始信号之后，包括：按照预置规则对所述原始信号进行映射处理，得到对应的输入信号。即对于客户端接收的原始信号可以通过映射处理得到能够被服务提供设备识别的输入信号，其中，映射得到的输入信号的类型可以有多种，如指定系统的标准输入信号，又如数字信息等。
以客户端传输指定系统的标准输入信号给服务提供设备为例，具体包括如下步骤：
参照图4，示出了本申请的一种客户端侧的数据传输方法实施例的步骤流程图。
步骤402，客户端在启动后与服务提供设备建立加密连接。
客户端启动后会请求服务器为其分配服务提供设备，而后客户端会与分配的服务提供设备建立连接，即启动SSL Socket Client，与服务提供设备的SSL Socket Server建立TCP长连接。其中，SSL Socket Client为客户端用来向服务提供设备传输加密输入信号的客户端应用。
本申请一个可选实施例中，客户端与所述服务提供设备按照心跳方式维持加密连接，在检测到连接断开后自动执行重连步骤。
客户端和服务提供设备可以使用心跳维持连接，客户端检测到与服务提供设备断连后会自动重连，其中数据传输使用SSL加密。
步骤404，接收原始信号。
步骤406，检测所述原始信号是否属于指定系统的标准输入信号。
客户端解析服务提供设备传输的TS流显示UI界面后，可以接收用户通过外置设备发出的原始信号，再检测该原始信号是否属于指定系统的标准输入信号。
其中，该指定系统为服务提供设备所采用的操作系统，则指定系统的标准输入信号即为服务提供设备的操作系统能够识别的输入信号，如为Linux标准输入信号等。
若是，即该原始信号属于指定系统的标准输入信号，执行步骤410。
若否，即该原始信号不属于指定系统的标准输入信号，执行步骤408。
步骤408，将所述原始信号映射成指定系统的标准输入信号。
该原始信号不属于指定系统的标准输入信号时，按照预置规则对所述原始信号进行映射处理，将所述原始信号映射成指定系统的标准输入信号。
步骤410，将所述指定系统的标准输入信号进行二进制化处理，得到二进制的输入信号。
步骤412，将所述二进制的输入信号进行对称加密或非对称加密，得到加密的输入信号。
步骤414，将加密的输入信号发送给所述服务提供设备。
将所述指定系统的标准输入信号进行二进制化处理，即将该标准输入信号转换成二进制信息得到二进制的输入信号。再对该二进制的输入信号进行加密处理，其中按照SSL加密连接建立时确定的加密方式进行对称加密或非对称加密，从而得到加密的输入信号。然后将该加密的输入信号发送给服务提供设备，使服务提供设备对其进行响应反馈对应的响应信息，如响应于控制的UI界面对应TS流。如客户端采用SSL Socket Client将输入信号进行二进制化后加密，传递给服务提供设备的SSL Socket Server。
步骤416，接收所述服务提供设备反馈的响应信息。
客户端接收服务提供设备反馈的响应信息，其中，所述响应信息包括对响应于输入信号的用户界面缓存编码生成的传送流。
步骤418，对所述传送流进行解析，显示响应于所述输入信号的用户界面。
客户端通过播放器对服务提供设备反馈的传送流进行解析，显示响应于所述输入信号的用户界面，如进入选择的功能对应UI界面，又如显示安装APP成功的UI界面等。
现有的输入信号透传技术通常是通过上层应用实现的，存在以下问题：一是可移植性差，二是支持虚拟设备种类少，三是安全性差，四是传输效率低。
而本申请实施例中，首先对客户端所采用的各种系统平台，可以将输入信号映射为Linux的输入信号传递至服务提供设备即可，可移植性较好。其次服务提供设备使用虚拟输入设备技术，直接将输入信号写入设备中，模拟硬件输入信号，可以模拟已知的所有输入设备，如触摸屏、键盘、遥控器、鼠标等，支持虚拟设备种类多，可扩展性较好。再次，客户端和服务提供设备间使用SSL对传输数据进行加密，保证数据传输的可靠性，解决了输入信号容易被恶意劫持，泄露用户密码等问题，安全性较高。再次，在使用字符串传输信号时，以“128”为例，使用字符串需要3个字节，而本申请采用二进制传输信号需要1个字节，大大提高传输效率，即使在网络状况不佳的情况下也能正常工作。
以客户端传输键值信息映射成数字信息作为输入信号给服务提供设备为例，具体包括如下步骤：
参照图5，示出了本申请的另一种客户端侧的数据传输方法实施例的步骤流程图。
步骤502，客户端在启动后与服务提供设备建立加密连接。
客户端启动后会请求服务器为其分配服务提供设备，而后客户端会与分配的服务提供设备建立连接，即启动SSL Socket Client，与服务提供设备的SSL Socket Server建立TCP长连接。其中，SSL Socket Client为客户端用来向服务提供设备传输加密输入信号的客户端应用。客户端和服务提供设备可以使用心跳维持连接，客户端检测到与服务提供设备断连后会自动重连，其中数据传输使用SSL加密。
步骤504，接收原始信号。
步骤506，对操作系统进行检测。
客户端解析服务提供设备传输的TS流显示UI界面后，可以接收用户通过外置设备发出的原始信号，并对客户端的操作系统(Operating System，OS)进行检测，当客户端为第一操作系统时，执行步骤408；当客户端为第二操作系统时，执行步骤410。
例如，用户通过红外遥控器发出红外键值信号，客户端获取红外信号并判断自身OS类型，假设第一操作系统为linux，第二操作系统为android。当然操作系统还可以为IOS等，本申请实施例对此不作限定。
步骤508，确定所述原始信号对应的键值，按照键值映射表获取所述键值对应的键值信息。
当属于第一操作系统时，确定所述原始信号对应的键值，按照键值映射表获取所述 键值对应的键值信息，如将红外键值与map表进行比较，确定红外键值代表的含义，即将红外键值Map成对应事件。其中，Map可以将键映射到值的对象。
步骤510，通过监听获取所述原始输入信号的按键响应，依据所述按键响应获取对应的键值信息。
当属于第二操作系统时，通过监听获取所述原始输入信号的按键响应，依据所述按键响应获取对应的键值信息，如启动按键监听按键响应获取按键事件，然后获取该按键事件对应的键值信息。
步骤512，将所述键值信息映射成数字信息作为输入信号。
步骤514，将所述键值信息进行对称加密或非对称加密，得到加密的输入信号。
步骤516，将加密的输入信号发送给所述服务提供设备。
将上述键值信息映射成数字信息作为输入信号，然后对键值信息进行对称加密或非对称加密，得到加密的输入信号。例如，将键值信息按照预设协议Map成数字信息，然后将数字信息按照加密算法加密成密文，如通过数据加密标准(Data Encryption Standard，DES)方式进行加密，得到加密的输入信号。然后将加密的输入信号发送给所述服务提供设备。如，将加密的输入信号通过IP网络采用SSL Socket Client发送给服务提供设备。
步骤518，接收所述服务提供设备反馈的响应信息。
客户端接收服务提供设备反馈的响应信息，其中，所述响应信息包括对响应于输入信号的用户界面缓存编码生成的传送流。
步骤520，对所述传送流进行解析，显示响应于所述输入信号的用户界面。
客户端通过播放器对服务提供设备反馈的传送流进行解析，显示响应于所述输入信号的用户界面，如进入选择的功能对应UI界面，又如显示安装APP成功的UI界面等。
当前客户端的UI界面以及对界面内容的控制均是在客户端本地的操作系统上运行，而没有实现对操作系统的云端化响应控制，而且对于UI的按键控制，通常也是在本地采用一个遥控器控制一种终端设备的实现方式。
本实施例采用强大的后台服务器将操作系统云端化，该操作系统云端化指的是客户端所显示的UI对应操作系统位于云端的服务提供设备中，因此对于UI界面的控制如APP的安装均是在服务提供设备侧实现的，而在客户端解析、显示。由于是服务提供设备实现操作系统及相应的控制，因此涉及到各种类型客户端和服务提供设备之间的远程按键操作等输入控制。本实施例可以兼容多种现有的不同类型的客户端和服务提供设备之间的按键上报等输入信号的传输，并且通过自定义协议将按键map(将键映射到值的对象) 后最大限度的减少传输带宽，并且采用键值算法加密和SSL证书认证双重安全保障。
综上，将客户端接收到的输入信号进行映射之后传递至服务提供设备，服务提供设备无需连接其他输入设备，也无需安装其他输入设备驱动，使用虚拟输入设备即可虚拟客户端上的输入，与直接在服务提供设备上输入无异，信号传输使用SSL加密，确保传输的安全性。
实施例三
在上述实施例的基础上，本实施例结合服务提供设备和客户端的交互举例论述该数据传输方法。
1、对指定操作系统的标准输入信号的传输。
参照图6，示出了本申请的一种客户端和服务提供设备间数据传输示意图。
6.02、客户端在启动后与服务提供设备建立加密连接。
6.04、服务提供设备生成虚拟输入设备。
6.06、客户端接收原始信号。
6.08、客户端映射得到指定系统的标准输入信号。
6.10、客户端将所述指定系统的标准输入信号进行二进制化处理，得到二进制的输入信号。
6.12、客户端将所述二进制的输入信号进行加密处理，得到加密的输入信号。
6.14、客户端将加密的输入信号发送给所述服务提供设备。
6.16、服务提供设备对所述加密的输入信号进行解密，获取解密的二进制输入信号。
6.18、服务提供设备将解密的输入信号写入所述虚拟输入设备。
6.20、服务提供设备的虚拟输入设备确定所述解密的输入信号对应的输入事件。
6.22、服务提供设备的虚拟输入设备将所述输入事件分发给上层应用或操作系统进行响应处理，生成对应的响应信息，包括响应的TS流。
6.24、服务提供设备将响应的TS流反馈给客户端。
6.26、客户端对响应的TS流进行解析，显示响应于所述输入信号的UI界面。
本实施例中，客户端的一种表现形式为APP，则为了使配置较为差的机顶盒等硬件设备，能够使用服务提供设备提供的优质服务(包括系统UI，影视剧，游戏，教育等各种资源)，将提供数据服务器的服务提供设备放入云端，与服务器、客户端等构成智能电视系统。通过TS流的形式向客户端推送视频信号(显示信息)，客户端解析TS流展示UI，并且发送控制信号(输入信号)到服务提供设备实现交互，从而实现了将控制信 号(输入信号)透传到服务提供设备进行云端响应。
2、键值信息作为输入信号的传输
参照图7，示出了本申请的另一种客户端和服务提供设备间数据传输示意图。
7.02、客户端在启动后与服务提供设备建立加密连接。
7.04、服务提供设备生成虚拟输入设备。
7.06、客户端接收原始信号。
7.08、客户端确定所述原始信号对应的键值信息。
7.10、客户端将所述键值信息映射成数字信息作为输入信号。
7.12、客户端将所述键值信息进行加密处理，得到加密的输入信号。
7.14、客户端将加密的输入信号发送给所述服务提供设备。
7.16、服务提供设备对所述加密的输入信号进行解密，获取解密的数字信息。
7.18、服务提供设备将解密的数字信息映射成键值信息。
7.20、服务提供设备将键值信息写入所述虚拟输入设备。
7.22、服务提供设备的虚拟输入设备确定所述键值信息对应的输入事件。
7.24、服务提供设备的虚拟输入设备将所述输入事件分发给上层应用或操作系统进行响应处理，生成对应的响应信息，包括响应的TS流。
7.26、服务提供设备将响应的TS流反馈给客户端。
7.28、客户端对响应的TS流进行解析，显示响应于所述输入信号的UI界面。
本实施例中，服务提供设备中存储的UI缓存包括在客户端上显示的各种内容，如主UI界面，UI界面中所显示的各种APP、以及APP开启后相应的UI界面等，即客户端本地仅显示而并不存储主UI界面，也不存储安装的APP等内容。
以用户在客户端中安装APP为例，用户通过外置设备发出对客户端显示的UI界面中的某一APP的安装指令后，客户端会获取该安装指令对应原始信号通过映射、加密等生成加密的输入信号发送给服务提供设备，服务提供设备对输入信号界面、映射等处理后，响应于该输入信号获取该APP的数据在服务提供设备端安装并记录相应的APP信息，并将安装过程以及安装完毕对应UI界面的TS流作为响应信息反馈给客户端进行显示。从而看似在客户端中安装APP的过程实质上是在服务提供设备中完成的，而客户端仅显示了服务提供设备推送的流化方式的UI界面。
又如用户通过外置设备选择开启已安装的某一游戏APP后，将对应加密的输入信号发送给服务提供设备后，服务提供设备响应于该输入信号会获取启动进入APP相应的 UI缓存生成TS流作为响应信息发送给客户端显示，后续对于客户端发送的各种控制数据，服务提供设备也会发送响应控制数据的UI缓存对应TS流，客户端显示响应于用户控制的UI界面。
因而，服务提供设备可以预先购买游戏、视频等付费资源供系统中各客户端使用，从而用户可以客户端本地免费选择上述资源进行安装、观看等。
从而通过服务提供设备采用TS流推送UI界面，客户端仅解析并显示，对于用户通过外置设备的控制数据也要转发给服务提供设备，由服务提供设备响应该控制调整UI界面反馈TS流。
上述各实施例所论述的客户端以及服务提供设备等，可以采用如下的智能电视系统。该智能电视系统可以包括：客户端、调度服务器和服务提供设备。其中，客户端是一种可以使用服务提供设备提供的APP应用程序的终端，如，机顶盒、智能移动终端、PAD(Portable Android Device平板电脑)、具有解码功能的智能电视等。所述服务提供设备可以是多个，作为服务端设置在云端，远程为所述客户端提供服务。调度服务器在接收到客户端申请服务提供设备的请求之后，可以根据设定分配策略从云端的多个服务提供设备中选择一个服务提供设备分配给所述客户端。
这里需要说明的是，在本申请的方案中，服务提供设备可以作为硬件设备设置在云端，软件(应用程序)可以安装在服务提供设备中，服务提供设备可以在云端将各类应用程序的用户界面(User Interface，UI)进行压缩编码，客户端有基本解码能力即可向用户展现应用程序的用户界面，实现对各类应用程序的操作。换而言之，与传统的智能电视系统所不同的是，在本申请的方案中，软件(应用程序)不再安装在机顶盒中，而是安装在服务提供设备中，通过服务提供设备为用户提供服务。由于不再需要将软件安装在机顶盒中，故可以不再单独设置机顶盒。例如，若所述客户端为智能移动终端、或具有解码功能的智能电视时，则可以直接将智能移动终端(或具有解码功能的智能电视)与所述服务提供设备进行连接，用户不需要单独购买/设置机顶盒，节约了用户成本；同时，智能移动终端(或具有解码功能的智能电视)与所述服务提供设备直接进行交互，提高了交互效率，减少了对机顶盒的维护步骤，降低了对资源的占用。当然，对现有具有基本解码能力的机顶盒本申请的方案也仍然适用。进一步地，所述调度服务器可以是指一个服务器，也可以是指等同于所述调度服务器功能的多个服务器组成的服务器群组。
本申请中，一种优选的智能电视系统的架构如图8所示，参照图8，示出了本申请的一种智能电视系统的架构图。在本实施例中，所述智能电视系统具体可以包括：至少 一个设备服务器(如图8所示的设备服务器801)、至少一个调度服务器(如图8所示的调度服务器802)和至少一个客户端(如图1所示的客户端803)。其中，每个设备服务器中包括至少一个服务提供设备(如图8所示的设备服务器801中的服务提供设备804)。
此外，优选地，所述智能电视系统还可以包括：至少一个管理服务器(如图8所示的管理服务器805)和至少一个用户数据信息存储设备(如图8所示的用户数据信息存储设备806)。需要说明的是，所述用户数据信息存储设备用于存储用户数据信息，一个用户可以对应一个专用的用户数据信息存储设备，多个用户也可以共有同一个用户数据信息存储设备，本实施例对此不作限制。其中，所述用户数据信息存储设备可以是物理设备，也可以是逻辑设备，还可以是物理和逻辑相结合的设备。例如，所述用户数据信息存储设备中可以包括至少一个用户分区(如图8所示的用户分区807)，每个用户分区对应存储一个用户的用户数据信息。
在本实施例中，客户端803可以是如上所述的硬件设备，如，机顶盒、智能移动终端、PAD、具有解码功能的智能电视等。优选地，所述客户端803也可以是位于智能电视终端侧，其可以呈现为智能电视终端中装载的APP(应用程序，Application)的形式，这里的智能电视终端具体可以包括：机顶盒、移动终端、智能电视机等。一方面，客户端803可用于播放服务提供设备804发送的传送流(Transport Stream，TS)所解析出的用户界面，以及播放从其他网络服务器中获取的多媒体数据(如视频信号、音频信号等)；另一方面，客户端803可用于监听用户通过遥控器等输入装置产生的输入消息，并将该输入消息发送给服务提供设备804或者调度服务器802。从而客户端803所显示的用户界面由服务提供设备804推送，客户端803仅解析并显示，且客户端803所接收的用户对用户界面控制的输入消息，也会转发给服务提供设备804以使其据此调整用户界面。
服务提供设备804位于网络侧，其中，每个服务提供设备具体可以包括：硬件板卡和硬件板卡所承载的软件模块。需要说明的是，在本实施例中，各类应用程序可以直接安装在服务提供设备中，用户可以通过客户端803展现的应用程序对应的用户界面，对服务提供设备804中的应用程序进行各项操作，不再需要在客户端803中单独安装应用程序，便于技术人员对所述智能电视系统进行统一维护，减少了工作量，提高了维护效率。
用户分区807位于网络侧，一般地，每个用户对应有一个用户分区，各个用户的用户数据信息被保存在对应的用户分区下。进一步地，每个用户分区具有唯一一个地址信 息，所述地址信息可以指示对应的用户分区的具体地址，通过所述地址信息可以快速查找到用户分区，完成用户数据信息的调用。换而言之，调度服务器802(或，管理服务器805)可以仅对地址信息(数据量较小)进行维护，而不用对整个用户数据信息(数据量较大)进行维护，降低了维护的数据量，减少了资源占用，提高了系统运行速度，且，数据信息便于查找。
调度服务器802位于网络侧，主要用于依据客户端803发送的输入消息，分配一个空闲的、状态良好的服务提供设备804与客户端803对接；同时，可以将用户ID对应的用户分区挂载到所分配的服务提供设备804上，也即，每个用户分区可以与唯一的用户ID相对应，如用户分区A对应用户A等等，这样，用户A在客户端803在与上次分配的、编号为001的服务提供设备断开连接后，即使下次连接的是编号为002的服务提供设备，用户A仍然可以使用用户分区A，并且可以使用之前的历史记录等数据；
管理服务器805位于网络侧，可用于对所有的服务提供设备进行管理，所述管理具体可以包括：状态上报、心跳管理、设置属性、获取属性、网络唤醒、软重启、硬重启等；可见，管理服务器805可以作为远程服务器，采用本申请的技术方案在广域网实现对服务提供设备的网络唤醒。
本申请实施例中，服务提供设备也可以称为云盒或OTT机顶盒，具有优质的服务能力，能够为用户提供各种功能如高清视频、免费游戏等，其中，OTT即Over The Top，是指通过互联网向用户提供各种应用服务。将具有OTT功能的服务提供设备集成为设备服务器，通过视频流化技术，将服务提供设备的功能通过网络传输到普通机顶盒、智能电视等设备上，使其可以在不升级硬件的情况下使用OTT的高端功能。
可以将具有优质服务能力的服务提供设备中的各种功能，通过流化方式传输给安装于普通低端机顶盒或智能电视中的客户端上，客户端显示TS流对应的UI界面，其中，服务提供设备的功能包括但不限于：游戏、应用、电影、电视剧、教育、视频聊天、K歌等。
其中，对于安装客户端的普通机顶盒或智能电视的系统要求较低，例如，要求普通机顶盒具备播放RTSP 720P视频流的能力，又如，要求普通机顶盒需要具备访问IP网络的能力，从而在安装了客户端后可以上传键值等进行控制。
本实施例中，设备服务器中的每一片服务提供设备，具备较强的服务能力，这些服务能力包括但不限于：较强的处理能力、较强的图形计算能力、大内存、低功耗。可以运行目前市面上的大型游戏和应用，播放1080P以及2K的电影等。
而普通的机顶盒往往较为陈旧，首先其并非是智能的OTT机顶盒，其次其性能也比较弱，不足以运行大型游戏和应用，客户往往需要升级或者替换更新的机顶盒才能满足这部分的娱乐需求。因此，服务提供设备能够解决上述问题。大型的游戏和应用都在云端的设备服务器中运行，再通过RTSP视频流传输给普通的机顶盒中安装的客户端进行播放，达到了使用低端机顶盒进行高端娱乐的目的，能够增强普通机顶盒的服务能力。
上述各实施例所述的客户端可以应用于基于图8中所示的智能电视系统中。但本领域技术人员应当明了，任意需要类似资源分配的系统或服务器，均可参照本申请实施例实现本申请的资源分配方案，而不仅限于上述架构下的应用场景。例如，所述资源分配方案还可以应用于对终端的远程控制系统(如，远程教学系统)等。
需要说明的是，对于方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本申请实施例并不受所描述的动作顺序的限制，因为依据本申请实施例，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中所描述的实施例均属于优选实施例，所涉及的动作并不一定是本申请实施例所必须的。
