本申请一个可选实施例中，所述定制应用模块，还用于向调度服务器请求分配服务提供设备，与分配的服务提供设备建立连接；以及在申请分配服务提供设备和/或连接分配的服务提供设备时，发送用户数据以进行鉴权。即定制应用模块向调度服务器请求分配服务提供设备，与分配的服务提供设备建立连接；在申请分配服务提供设备和/或连接分配的服务提供设备时，所述定制应用模块发送用户数据给所述调度服务器以进行鉴权。
其中，定制应用模块在与服务提供设备建立连接时可以建立加密连接。客户端启动后定制应用模块会请求服务器为其分配服务提供设备，而后定制应用模块会与分配的服务提供设备建立连接，如启动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。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。客户端块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。

本实施例中，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。
1、从传送流到多媒体数据的切换。
其中，步骤306所述执行传送流和多媒体数据的传输切换，包括：传送流到多媒体数据的传输切换，所述传输切换包括如下步骤：向所述服务提供设备发送第一指令以暂停推送数据流，并向所述网络服务器请求获取播放多媒体数据；接收所述网络服务器反馈的多媒体数据；对所述多媒体数据进行解析显示相应的多媒体内容。
其中，所述定制应用模块，用于发送多媒体播放请求给所述服务提供设备，接收服 务提供设备反馈的多媒体播放信息；向所述服务提供设备发送传送第一指令并向所述内容分发服务器请求获取播放多媒体数据，获取内容分发服务器反馈的多媒体数据，将获取的多媒体数据发送给所述解码模块，从而解码模块解析多媒体数据，播放模块切换成显示解析的多媒体数据对应多媒体内容。
参照图4，示出了本申请的一种传送流和多媒体数据的切换方法实施例的步骤流程图，具体可以包括如下步骤：
步骤402，定制应用模块接收服务提供设备推送的依据用户界面缓存编码生成的传送流，将所述传送流发送给解码模块。
步骤404，所述解码模块对所述传送流进行解析，将解析后的传送流发送给播放模块。
步骤406，所述播放模块依据所述解析后的传送流显示相应的用户界面。
步骤408，所述定制应用模块发送多媒体播放信息请求给所述服务提供设备，以获取多媒体播放信息。
步骤410，所述定制应用模块向所述服务提供设备发送传送第一指令并向所述内容分发服务器请求获取播放多媒体数据。
步骤412，所述定制应用模块将获取的多媒体数据发送给所述解码模块。
步骤414，所述解码模块对所述多媒体数据进行解析，将解析后的多媒体数据发送给播放模块。
步骤416，所述播放模块依据所述解析后的多媒体数据切换成显示相应的多媒体内容。
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，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。客户端的定制应用模块在接收到TS流后会将该TS流发送给解码模块进行解析，而后生成相应的解析数据发送给播放模块进行播放从而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。
用户使用客户端时可能需要播放多媒体资源，如播放音、视频数据等，特别是数据量大、清晰度要求高的视频资源，此时定制应用模块可以发送多媒体播放请求给服务提供设备。本实施例中服务提供设备可以不直接提供客户端播放的多媒体数据，而是将相应的多媒体播放信息反馈给客户端。
定制应用模块获取多媒体播放信息后，从该多媒体播放信息中获取播放地址，向网络服务器，如内容分发(Content Delivery Network，CDN)服务器请求获取播放多媒体数据，同时向服务提供设备发送传送第一指令以暂停服务提供设备对所述传送流的推送。然后，接收CDN服务器反馈的多媒体数据，将多媒体数据发送给解码模块进行解析，相应播放器由对TS流的播放切换成对多媒体资源的播放。即所述第一指令用于标识当前准备播放多媒体数据，可以暂停推送传送流。
2、从多媒体数据切换回传送流。
其中，步骤306所述执行传送流和多媒体数据的传输切换，还包括：多媒体数据到传送流的传输切换，所述传输切换包括如下步骤：在需要停止播放所述多媒体数据时，发送第二指令给所述服务提供设备；接收所述服务提供设备反馈的传送流；对所述传送流进行解析显示相应的用户界面。
所述定制应用模块，用于在需要停止播放所述多媒体数据时，生成第二指令发送给所述服务提供设备；接收所述服务提供设备依据所述第二指令反馈的第三指令以及相应的传送流。再将所述传送流发送给所述解码模块，由解码模块对所述传送流进行解析，将解析后的传送流发送给播放模块，播放模块依据所述解析后的传送流切换回显示相应的用户界面。
参照图5，示出了本申请的一种传送流和多媒体数据的切换方法实施例的步骤流程图，具体可以包括如下步骤：
步骤502，所述定制应用模块在需要停止播放所述多媒体数据时，生成第二指令发送给所述服务提供设备。
步骤504，所述定制应用模块接收所述服务提供设备依据所述第二指令反馈的第三指令以及相应的传送流。
步骤506，所述定制应用模块将所述传送流发送给所述解码模块。
步骤508，所述解码模块对所述传送流进行解析，将解析后的传送流发送给播放模 块。
步骤510，所述播放模块依据所述解析后的传送流切换回显示相应的用户界面。
当定制应用模块确定对多媒体资源播放完毕或者用户指示停止播放多媒体资源时，客户端可以从多媒体数据的播放切换回UI界面的播放，则在停止对多媒体数据的解析并停止采用播放器播放所述多媒体数据时，客户端需要执行TS流重启(restart)动作，因此定制应用模块触发生成第二指令，第二指令用于通知服务器恢复推送TS流，因此可以将第二指令发送给服务提供设备。服务提供设备依据该第二指令准备TS流，该TS流可以承接在播放多媒体数据前暂停推送的TS流，即服务提供设备依据记录恢复暂停推送的TS流，在TS流准备完成后生成第三指令，如完成(ready)指令，该第三指令用于告知客户端TS流准备完毕，而后继续推送TS流，当然该TS流也可以推送UI主界面的TS流，可以依据实际需求确定。定制应用模块依据该第三指令停止确定TS准备完毕，并将接收到的TS流发送给解码模块进行解析，再由播放模块切换回显示相应的UI界面。
本实施例客户端显示的UI界面由服务提供设备通过TS流推送，而多媒体资源从网络的CDN服务器中直接获取播放，通过上述步骤实现了客户端对TS流播放和对多媒体数据播放之间的无缝切换，使得多媒体数据播放前后的UI界面可以保持连续性，不会对用户感知产生影响。
本实施例中，由于服务提供设备的数据的传输是通过IP网络进行的，因此对于网络的带宽会有相应的要求，例如，当运行商的专网平均带宽为4M等较低带宽时对TS流的码率由一定的要求。但是，电影、电视剧等多媒体资源的片源规格比较大，如规格为高清、1080P甚至蓝光等，像这种高清视频片源在现有编码压缩技术下是无法达到4M以内的码率，即若在4M网络带宽环境下用流化方案对高清片源的损耗会比较大。
因此本实施例中，针对高清视频等多媒体资源的多媒体数据直接从网络中获取，而不采用TS流方式传输。由于在播放多媒体资源时可以从第三方的CDN服务器上获取，因此上述切换等过程中需要涉及到用户数据的保存，本实施例中，可以采用账号模式登陆服务提供设备，每个账户对应着用户存储区，保证用户享受多媒体数据切流服务的账号和数据的同步。
本实施例中，客户端所播放UI界面的动态帧率并不高，因此其对应UI缓存在压缩后的码率是可控的，因此对于UI界面采用流化的服务提供设备端推送，客户端显示；而对于用户需求较高的多媒体资源如影视资源、游戏等，采用互联网的CDN方式播放，因此要实现UI界面播放和多媒体数据播放的无缝切流显示，达到良好的用户感官体验。
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，对客户端中用户界面的控制方法的步骤包括：接收外置设备发送的原始输入信号；依据所述原始输入信号向服务提供设备反馈对应的输入信息以进行用户界面的控制；接收所述服务提供设备发送的响应于输入信号的传送流，所述响应于输入信号的传送流为基于所述输入信息控制用户界面后生成的；对所述传送流进行解析显示相应控制的用户界面。
其中，所述接收外置设备发送的原始输入信号之后，还包括：将所述原始输入信息映射成能够被所述服务提供设备识别的输入信号，其中，所述输入信号包括指定系统的标准输入信号或键值信息或数字信息。
所述输入接收模块，用于接收外置设备发送的原始输入信号，将所述原始输入信号发送给所述定制应用模块；所述定制应用模块，还用于对所述原始输入信号进行映射处理得到输入信号，再对所述输入信号进行加密处理，将加密的输入信号发送给所述服务提供设备；以及接收所述服务提供设备发送的响应于输入信号的响应信息，其中，所述响应信息包括响应于输入信号的用户界面对应传送流。
参照图6，示出了本申请的一种客户端输入处理方法实施例的步骤流程图，具体可以包括如下步骤：
步骤602，定制应用模块接收服务提供设备推送的依据用户界面缓存编码生成的传送流，将所述传送流发送给解码模块。
步骤604，所述解码模块对所述传送流进行解析，将解析后的传送流发送给播放模块。
步骤606，所述播放模块依据所述解析后的传送流显示相应的用户界面。
步骤608，输入接收模块接收外置设备发送的原始输入信号，将所述原始输入信号发送给所述定制应用模块。
步骤610，所述定制应用模块对所述原始输入信号进行映射处理得到输入信号，再对所述输入信号进行加密处理，将加密的输入信号发送给所述服务提供设备。
步骤612，所述定制应用模块接收所述服务提供设备发送的响应于输入信号的响应信息，将所述响应信息中的传送流发送给所述解码模块。
步骤614，所述解码模块对所述传送流进行解析，将解析后的传送流发送给播放模 块。
步骤616，所述播放模块依据所述解析后的传送流显示响应于输入信号的用户界面。
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，对应输入接收模块接收原始输入信号，所述定制应用模块对所述原始输入信号进行映射处理得到输入信号，再对所述输入信号进行加密处理，将加密的输入信号发送给所述服务提供设备，服务提供设备获取该APP的数据在服务提供设备端安装并记录相应的APP信息，并传送安装过程以及安装完毕对应UI界面的TS流作为响应信息发送给客户端，客户端的定制应用模块接收所述服务提供设备发送的响应于输入信号的响应信息，将所述响应信息中的TS流发送给所述解码模块进行解析，播放模块依据所述解析后的传送流显示响应于输入信号的UI界面。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，输入接收模块将原始输入信号发送给定制应用模块处理后发送给服务提供设备后，服务提供设备会获取启动进入APP相应的UI缓存生成TS流作为响应信息发送给客户端，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。
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。
1、对于标准输入信号的传输
本申请一个可选实施例中，定制应用模块，用于当检测到所述原始输入信号不属于指定系统的标准输入信号时，将所述原始输入信号映射成指定系统的标准输入信号。
参照图7，示出了本申请的一种客户端的输入信号传输方法实施例的步骤流程图。

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606。
步骤706，所述定制应用模块将所述原始输入信号映射成指定系统的标准输入信号。
步骤708，所述定制应用模块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712，所述定制应用模块将加密的输入信号发送给所述服务提供设备。
所述定制应用模块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，时服务提供设备对其响应反馈对应的响应信号。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714，所述定制应用模块接收所述服务提供设备发送的响应于输入信号的响应信息，将所述响应信息中的传送流发送给所述解码模块。

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。
而本申请实施例中，首先无论客户端采用何种平台，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。
2、对于数字信息的传输
本申请另一个可选实施例中，所述定制应用模块，用于对操作系统进行检测；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；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；将所述键值信息映射成数字信息作为输入信号。
参照图8，示出了本申请的另一种客户端的输入信号传输方法实施例的步骤流程图。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。
步骤802，输入接收模块接收外置设备发送的原始输入信号，将所述原始输入信号发送给所述定制应用模块。
步骤804，所述定制应用模块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输入信号，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806；当客户端为第二操作系统时，执行步骤808。
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806，所述定制应用模块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808，所述定制应用模块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810，定制应用模块将所述键值信息映射成数字信息作为输入信号。
步骤812，所述定制应用模块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814，所述定制应用模块将加密的输入信号发送给服务提供设备。
所述定制应用模块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816，所述定制应用模块接收所述服务提供设备发送的响应于输入信号的响应信息，将所述响应信息中的传送流发送给所述解码模块。
步骤818，所述解码模块对所述传送流进行解析，将解析后的传送流发送给播放模块。
步骤820，所述播放模块依据所述解析后的传送流显示响应于输入信号的用户界面。
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，而客户端仅用于显示。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。
本申请另一个可选实施例中，所述播放模块，还用于通过端口对服务提供设备推送的传送流进行监听，在监听到所述交互过程中服务提供设备发送的传送流中断时，确定所述服务提供设备出现异常状态，将所述服务提供设备的异常状态发送给所述定制应用模块；所述定制应用模块，还用于将服务提供设备的异常状态上报给调度服务器。该定制应用模块还用于执行异常状态重连。
参照图9，示出了本申请的另一种客户端针对异常状态的处理方法实施例的步骤流程图。
步骤902，所述播放模块通过端口对服务提供设备推送的传送流进行监听。
步骤904，在监听到所述交互过程中服务提供设备发送的传送流中断时，所述播放模块确定所述服务提供设备出现异常状态，将所述服务提供设备的异常状态发送给所述定制应用模块。
步骤906，所述定制应用模块执行异常状态重连处理。
步骤908，所述定制应用模块将服务提供设备的异常状态上报给管理服务器。
在客户端与服务提供设备的交互过程中，播放模块通过端口对服务提供设备推送的传送流进行监听，可以监听到所述交互过程中服务提供设备发送的TS流是否出现中断，当服务提供设备发送的TS流出现中断，确认为服务提供设备状态异常，服务提供设备状态异常可能是由于服务提供设备掉电、断网等原因引起的。所述播放模块将所述服务提供设备的异常状态发送给所述定制应用模块。
在由于服务提供设备状态异常而导致客户端和服务提供设备的连接断开时，所述定制应用模块可以启动计时器开始计时，而后尝试重新与该状态出现异常的服务提供设备建立连接，并在连接过程中检测计时时间是否达到重连阈值。当重连阈值内与所述服务提供设备重连成功，表征该服务提供设备状态已恢复正常，可以继续推送TS流则所述定制应用模块对应恢复从所述服务提供设备处接收TS流。当超过重连阈值与所述服务提供设备重连失败，为了防止无限重连影响客户端中场使用，该所述定制应用模块可以向系统中的管理服务器上报之前连接服务提供设备的服务提供设备状态异常，使得系统可以检测该服务提供设备的异常原因并进行处理。然后所述定制应用模块再向该调度服务器重新申请分配一个服务提供设备，与该重新分配的服务提供设备建立连接，而后由该重新分配的服务提供设备为其推送TS流，所述定制应用模块恢复从所述重新分配的服务提供设备处接收TS流。
本申请另一个可选实施例中，所述播放模块，还用于在播放解析的传送流时，对传送流的图像帧进行检测，当检测到所述图像帧异常时，丢弃所述图像帧。所述播放模块在播放解析的传送流时，对传送流的图像帧进行检测，例如TS流为每秒25帧，每帧100KB，若某一图像帧为90KB则说明该图像帧部分数据丢失，即检测到所述图像帧异常，此时可以丢弃所述图像帧。其中图像帧异常可以包括各种异常情况，如出现上述数据丢失问题，可能导致该帧图像出现花屏问题。从而通过播放模块实现对花屏的自动检测以及执行丢弃处理。
实施例三
在上述实施例的基础上，本实施例还公开了一种智能电视系统。
该智能电视系统，包括：至少一个如上述实施例所述的客户端、至少一个服务器和至少一个服务提供设备；其中，所述服务器用于向所述客户端分配服务提供设备；所述客户端设置在智能电视中，所述服务提供设备设置在网络侧，用于通过网络为建立连接的客户端提供互联网服务。
所述还包括至少一个用户数据信息存储设备；所述至少一个用户数据信息存储设备包括：至少一个用户分区；其中，所述至少一个用户分区分别用于存储不同客户端对应的用户数据。
所述服务提供设备包括：网络机顶盒；所述互联网服务，包括如下中的至少一个：电视直播、音视频服务、网页服务、游戏服务。
该客户端至少可以执行以下业务：1.接收用户的输入信号，将输入信号发送到服务提供设备端以完成双方的交互；2.解析服务提供设备端TS流并显示；3.网络安全的用户鉴权。因此，客户端可以支持以上几种基本核心功能：1.可以进行网络通信(cable/ip)；2.可以解析云端的数据传输流并输出；3.支持外置设备(如遥控器)输入；4.支持系统的用户鉴权机制；5.支持远程CDN视频请求和播放。
从而智能电视系统中客户端与各设备以及系统外部的CDN服务器交互如图10所示。
客户端的定制应用模块可以调度服务器交互申请分配服务提供设备以及执行鉴权处理；定制应用模块和管理服务器交互上报状态异常事件；定制应用模块和服务提供设备交互建立连接，从服务提供设备获取TS流和多媒体信息，以及将输入信号发送给服务提供设备进行响应；定制应用模块从CDN服务器获取多媒体数据。
即定制应用模块(定制app模块)的功能包括：1)加密和映射按键键值发送给服务提供设备；2)支持和服务器之间的申请服务提供设备和用户鉴权机制；3)TS流和多媒体数据切流的逻辑功能实现；4)TS流接收功能；5)CDN数据源的申请和接收。
客户端的输入接收模块(IR Receive模块)从外置输入设备中获取并发送给定制应用模块。
客户端的解码模块(Decoder模块)具有解码TS流和CDN视频流功能。
客户端的网络模块(Ethernet/WiFi)为设备网络功能支持。
客户端的播放模块(Media player)为TS流和CDN视频流播放器，该播放器为服务提供设备方案TS流定制播放器，主要优化功能：新增RTSP端口监听功能和自动检测花 屏丢帧功能。
客户端的操作系统模块(Smart os)为轻量级的智能操作系统，可以仅支持以上几大模块。
上述各实施例所涉及的智能电视系统中，采用的是界面UI，影视，游戏等内容都在云端，客户端是通过网络接收云端数据解码显示。其中云端数据传输到客户端的途径分为UI流化(TS流)和URL化(多媒体数据)切换使用。
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，客户端需要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，对有现有的具有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11所示，参照图11，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11所示的设备服务器1101)、至少一个调度服务器(如图11所示的调度服务器1102)和至少一个客户端(如图1所示的客户端1103)。其中，每个 设备服务器中包括至少一个服务提供设备(如图11所示的设备服务器1101中的服务提供设备1104)。
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11所示的管理服务器1105)和至少一个用户数据信息存储设备(如图11所示的用户数据信息存储设备1106)。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11所示的用户分区1107)，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1103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1103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1103可用于播放服务提供设备1104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1103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1104或者调度服务器1102。从而客户端1103所显示的用户界面由服务提供设备1104推送，客户端1103仅解析并显示，且客户端1103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1104以使其据此调整用户界面。
服务提供设备1104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1103展现的应用程序对应的用户界面，对服务提供设备1104中的应用程序进行各项操作，不再需要在客户端1103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1107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1102(或，管理服务器1105)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1102位于网络侧，主要用于依据客户端1103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1104与客户端1103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1104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1103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1105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1105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11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。
