其中，资源管理平台2包括：主机内部资源模块21，主机内部资源模块21用于提供主机内部资源。
需要说明的是，主机内部资源模块21是实现电视基本功能(如电视直播)时必需的模块，也就是说所有电视主机都包含的模块。主机内部资源就是主机实现电视基本功能时需要使用的相关部件。
其中，外接模块接口3用于连接外接模块；外部设备接口4用于连接外部设备。
需要说明的是，本申请实施例中根据设备与电视主机连接的接口类型将与电视主机上的接口分为外部模块接口和外部设备接口4。外部设备接口4是专有的，用于连接某一种或某一类设备，例如通过麦克风接口连接的麦克风，通过机顶盒接口连接的机顶盒；外部模块接口是通用的，用于连接所有满足一定标准的具有通用化接口的设备。例如通过USB连接的手机、鼠标等，通过HDMI(High Definition Multimedia Interface，高清晰度多媒体接口)接口连接的DVD播放器、电脑等。

Figure PCTCN2015072410-appb-000001
图2是外接模块接口3的一种示意图。其中，PQE(Picture Quality Engine，图像质量引擎)，支持Intel的联合色彩纠正与增强技术，相当于某种硬件/软件编码增强器。AV&YPbPr为AV(音频视频)接口和色差分量接口接口。ATV为模拟信号输入接口。VGA(Video Graphics Adapter，视频图形适配器)的信号类型为模拟信号。USB是一个外部总线标准，USB接口支持设备的即插即用和热插拔功能。DSP(digital signal processor，数字信号处理器)用于将电视主机的音频信号处理后传输给音频输出设备(如音响)。SPDIF用于传输数字音频信号。IR(infrared，红外线)接口是红外线接口。EEPROM(Electrically Erasable Programmable Read-Only  Memory，带电可擦可编程只读存储器)一种掉电后数据不丢失的存储芯片，一般用在即插即用。flash是存储芯片的一种，通过特定的程序可以修改里面的数据。FLASH即闪存，一种长寿命的非易失性(在断电情况下仍能保持所存储的数据信息)的存储器。DDR(Double Date Rate synchronous dynamic random-access memory，双倍速率同步动态随机存取內存)是通常的内存或主存。IR&RF Remote是红外线和无线射频遥控机。GPIO(General Purpose Input Output，通用输入/输出接口)是一种通用的数据接口。
其中，资源管理平台2，用于建立主机内部资源模块21、外接模块接口3以及外部设备接口4中至少两个之间数据通路。
资源管理平台2可以建立主机内部资源模块21、外接模块接口3以及外部设备接口4中至少两个之间数据通路，也可以建立主机内部资源模块21中至少两个单元间的数据通路。
需要说明的是，资源管理平台2建立数据通路可以是在电视主机开机时建立数据通路，也可以是在外接模块或者外部设备接入时，建立数据通路。数据通路传输的数据可以是控制信息，也可以是音视频信息，还可以是其他交互信息，本申请对此不做限制。
需要说明的是，资源管理平台2架建立外接模块接口3与外部设备接口4、主机内部资源模块21之间的数据通路后，连接至外接模块接口3的外接模块、连接至外部设备接口4的外部设备和主机内部资源模块21之间可以相互传输数据。也就是说连接至外接模块接口3的外接模块可以与外部设备和主机内部资源模块21之间传输数据。
示例性的，在连接至电视主机的外接模块是智能手机时，资源管理平台2建立外接模块接口3和主机内部资源模块21和外部设备接口4之间的数据通路。若外接设备中有是视屏输出设备，那么就可以通过该数据通路将智能手机中的视屏数据传输至主机内部资源模块21和外部设备上输出，同时将视屏在智能手机上输出，最终实现智能手机、电视主机和外部设备之间同步输出，扩展了电视主机的拓展功能。
本申请实施例提供一种电视主机，包括：电源、资源管理平台、外接模块接口以及外部设备接口；资源管理平台包括：主机内部资源模块，外接模块接口用于连接外接模块；外部设备接口用于连接外部设备；资源管理平台，用于建立主机内部资源模块、外接模块接口以及外部设备接口中至少两个之间数据通路。这样，由于 建立了主机内部资源模块、外接模块接口以及外部设备接口中至少两个之间数据通路，那么连接至外接模块接口的外接模块、连接至外部设备接口的外部设备和主机内部资源模块之间可以相互传输数据，也就是说，主机内部资源模块、外部设备和外接模块之间就能够通过该数据通路实现互联互通，如此以来，外接模块就可以调用其他外接模块或者外接设备或者主机内部资源模块，最终扩展电视拓展功能。
进一步的，如图3所示，资源管理平台2还包括：外接模块及系统信息管理模块22和主机资源管理模块23。
外接模块及系统信息管理模块22，用于监控外接模块的状态信息，并将外接模块的状态信息发送至主机资源管理模块23。
主机资源管理模块23，用于获取外接模块的状态信息；
主机资源管理模块23，还用于根据外接模块的状态信息建立主机内部资源模块21、外接模块接口3以及外部设备接口4中至少两个之间数据通路。
具体的，外接模块与系统信息管理模块持续监控连接至外接模块接口3的所有外接模块的状态信息，并将所有外接模块的状态信息发送至主机资源管理模块23，其中外接模块的状态信息包括外接模块类别、外接模块ID、外接模块工作状态信息(例如：前台工作时间、后台工作时间等)、外接模块输入信号等信息，主机资源管理模块23根据外接模块的状态信息将建立数据通路。
需要说明的是，外接模块与系统信息管理模块可以采用主动和被动两种模式获取连接至外接模块接口3的所有外接模块的状态信息。主动模式是外接模块与系统信息管理模块主动读取外接模块的状态信息，例如，在固定的时间间隔读取外接模块的工作状态、工作方式等信息；被动模式是外接模块与系统信息管理模块被动接收外接模块的状态信息，例如，外接模块按照预定要求收集状态信息，然后按照固定时间发送给主机。
需要说明的是，外部模块的种类具有较大灵活性，可以是任何支持外接模块接口3使用的协议的各种功能的外接模块，所以在此将外接模块按照工作模式分为两大类：主动型外接模块和被动型外接模块。
主动型外接模块具有独立自主的工作模式，能够借助外接模块接口3控制电视主机内部的各种资源，实现音视频处理和输出功能，具备网络功能的主动型外接模块能够实现与互联网的互联。该类外接模块主要包括智能机顶盒、数字电视机顶盒等。
被动型外接模块需要通过和电视主机内部的各种资源配合完成预定功能，大部 分情况下是电视主机部分功能的补充或者升级，一般不具备独立自主的工作模式。例如，大容量存储模块、压缩编码模块等。两种外接模块具有一些共性特征，例如都必须具备标准的设备信息，告诉电视主机设备的功能和相关信息；都必须支持主机的电源管理模式；都支持热插拔，支持网络接口等。
进一步的，在外接模块包括：主动型外接模块的情况下，主机资源管理模块23，具体用于在根据连接至外接模块接口3的外接模块的设备信息识别出连接至外接模块接口3的外接模块是主动型外接模块的情况下，分别建立外接模块接口3与主机内部资源模块21、外部设备接口4之间的数据通路，相应的，外接模块接口3，还用于传输主动型外接设备的控制信息。
需要说明的是，主动型外接模块可以将自身的资源在主机上呈现，也可以由电视主调用自身的资源；被动型外接模块只能由电视主调用自身的资源。
根据外部模块在主机内容的呈现模式，将外部模块的工作模式定义为前台工作模式和后台工作模式。具体说明如下：
当连接至外接模块接口3的外接模块是工作在控制电视主机状态下的主动型外接模块时，可以将电视主机的部分功能交给该外接模块管理，此时外接模块处于前台工作模式，对电视主机和连接至电视主机的外接模块及外部设备进行管理，电视主机处于后台工作模式，对电视主机内部的主机内部资源模块21和连接至电视主机的外接模块及外部设备的状态进行监控。例如：外接模块为一个智能电视模块，具备完整的智能电视功能，包括直播电视、网络视频、智能应用、交互游戏等功能，电视主机将此模块设为前台工作模式，智能电视模块显示的内容通过外接模块接口3在电视主机的显示屏呈现，此种模式下电视主机进入后台工作模式，将部分外设资源(例如：USB、HDMI等)、部分系统管理功能(例如：主机系统的图像产生、声音参数等)等功能开放给外接模块管理。该模式下主机资源管理模块23建立的数据通路如图4所示。
当连接至外接模块接口3的外接模块是被动型外接模块或者工作在被电视调用状态下的主动性外接模块时，外接模块只是作为存储设备或者输出设备或者输入设备，此时外接模块只能处于后台工作模式，为电视主机服务，电视主机处于前台工作模式，对电视主机内部的主机内部资源模块21和连接至电视主机的外接模块及外部设备的状态进行监控和管理。例如：外接模块为一个存储设备或者视频压缩设备，或者外接模块是只作为存储设备的智能电视模块，外接模块只是将电视主机工作过程中的数据进行记录或者处理，无需主机显示资源，此时电视主机继续保持前 台工作模式，执行正常的系统资源管理功能。该模式下主机资源管理模块23建立的数据通路如图5所示。
需要说明的是，本申请电视主机外接多个外接模块的情况下，默认只能支持电视主机或者一个外接模块工作在前台工作模式。
需要说明的是，外接模块的信息管理流程如图6所示。电视主机进入工作状态后，首先电视主机工作在前台工作模式，电视主机的资源管理平台2中的外接模块及系统信息管理模块22监控外接模块的状态信息，并将外接模块的状态信息发送至电视主机的资源管理平台2中的主机资源管理模块23。当外接模块接口3插入新的外接模块后，电视主机识别外接模块并读取外接模块的状态信息，在外接模块是主动型外接模块的情况下，电视主机切换到外接模块前台工作模式，电视主机进入后台工作模式；当电视主机切换回电视主机前台工作模式后，外接模块进入后台工作模式；所有过程中外接模块的状态信息改变都由电视主机的进行监控和记录。
需要说明的是，外接模块接入和移除流程如图7所示，外接模块接入电视主机后，电视主机读取外接模块的设备身份信息(包含于外接模块的状态信息)，根据外接模块的设备身份信息确定该外接模块是否为合法设备，在该外接模块不是合法设备的情况下，提示用户插入的外接模块为非法设备，释放与该外接模块连接的资源，进入等待接入状态；在该外接模块为合法设备的情况下，建立该外接模块与电视主机的连接后该外接模块进入工作状态。在检测到外接模块移除时，产生提示信息告诉电视主机外部模块移除，电视主机释放与该外接模块连接的资源，进入等待接入状态。
进一步的，如图3所示，资源管理平台2还包括：电源管理模块24和外部设备及交互管理模块25。
电源管理模块24，用于控制电源1向主机内部资源模块21、外接模块和外部设备供电；
外部设备及交互管理模块25，与外部设备接口4连接，用于监控外部设备的状态信息，并将外部设备的状态信息发送至外接模块及系统信息管理模块22；
主机内部资源模块21，还用于监控主机内部资源模块21的状态信息，并将主机内部资源模块21的状态信息发送至外接模块及系统信息管理模块22；
外接模块及系统信息管理模块，还用于获取主机内部资源模块21的状态信息和外部设备的状态信息，并将主机内部资源模块21的状态信息、外接模块的状态信息以及外部设备的状态信息发送至主机资源管理模块23；
主机资源管理模块23，还用于分别根据外接模块的状态信息和外部设备的状态信息，对外接模块和外部设备进行识别和注册。
需要说明的是，电源管理的效率直接影响整机功率消耗。由于外部设备和外接模块的动态工作特征，传统电视主机的电源管理方法需要根据各个资源管理模块、外部设备、HILINK连接外部模块等部件的工作状态动态调整电源管理策略，这种电源管理方法的效率较低。本申请实施例中的电源管理方案可以根据外部指令按照需要配置系统电源管理模式。此处，将电源管理方法分为：基本电源管理模式，高级电源管理模式，智能电源管理模式。在进入不同的电源管理模式之前电源启动流程如图8所示，首先电源管理模块24启动电视主机电源，进行电视主机检查，检查电视主机中的各个模块，然后检查连接至电视主机的外接模块和外部设备，随后启动电源管理服务程序，根据预设的电源管理模式，进入相应的电源管理模式。不同的电源管理模式的具体说明如下：
一、基本电源管理模式
该模式下电视主机中的电源1向所有主机内部资源模块21、连接至外接模块接口3的外接模块、连接至外部设备接口4的外部设备进行供电，所有设备处于全程带电状态，电源管理模块24只有在接收到外部指令的情况下，才根据外部指令关闭设备或者模块的电源。该模式下电源管理模块24的工作流程参见图9，电源管理模块24进入基本电源管理模式后，首先检查电视主机、连接至外接模块接口3的外接模块、连接至外部设备接口4的外部设备的电源信息，并实时监控电视主机或外接模块或外部设备的发送的控制电源管理的外部指令；电源管理模块24接收到外部指令，并对外部指令进行分析，根据外部指令关闭/待机主机内部资源模块、外接模块和外部设备；也可以启动/唤醒主机内部资源模块、外接模块和外部设备，还可以控制电视主机电源关闭或待机。
二、高级电源管理模式
该模式下电源管理模块24预先设置一种或多种电源管理方案，电源管理模块24检测到满足方案的工作条件后，自动启用相应的电源管理方案。例如，预置电视直播模式，当满足电视直播模式的工作条件(用户选择电视直播功能)后，电源1只向电视主机供电，不向连接至电视主机的外接模块和外部设备供电，只有在电源管理模块24接收到外部指令后，才控制电源1给外界模块和/或外部设备供电。该模式下电源管理模块24的工作流程参见图10，电源管理模块24进入高级电源管理模式后，首先检查电视主机、连接至外接模块接口3的外接模块、连接至外部设备 接口4的外部设备的电源信息，读取预置电源管理方案，然后检查预置的电源管理方案是否有效，因为如果外接模块或者外部设备出现异常或者移除或者重新接入等状况，原来预置的电源管理方案将无法有效工作，所以需要检查预置的电源管理方案是否有效，在确认预置的电源管理方案无效的情况下，产生错误信息并上报给主机资源管理模块23；在确认预置的电源管理方案有效的情况下，进入预置电源管理方案，并实时监控电视主机或外接模块或外部设备的发送的控制电源管理的外部指令；电源管理模块24接收到外部指令，并对外部指令进行分析，根据外部指令关闭/待机主机内部资源模块、外接模块和外部设备；也可以启动/唤醒主机内部资源模块、外接模块和外部设备，还可以控制电视主机电源关闭或待机。
三、智能电源管理模式
该模式下电源管理模块24自动监控电视主机中各个模块、各个外接模块、各个外部设备，如果某一模块或设备处于空闲时间的时长超过预定时间，将该模块或设备调整为关闭或待机。例如，主机长时间处于电视直播模式时，外接模块及外部设备处于空闲的时间过程，则自动关闭或待机外接模块及外部设备。该模式下电源管理模块24的工作流程参见图11，电源管理模块24进入智能电源管理模式后，首先检查电视主机、连接至外接模块接口3的外接模块、连接至外部设备接口4的外部设备的电源信息，并实时监控电视主机或外接模块或外部设备的工作状态信息，如果某一模块或设备进入空闲状态，则启动空闲状态计时功能，对处于空闲状态的模块或设备的空闲时间进行计时，当被计时的模块或设备空闲时间达到预定时间后，电源管理模块24提示用户是否需要将空闲模块或设备进行关闭/待机，如果用户确认需要将空闲模块(设备)进行关闭/待机，则将该模块(设备)进行关闭/待机；否则，电源管理模块24继续监控电视主机或外接模块或外部设备的工作状态信息。
外部设备及交互管理模块25，与外部设备接口4连接，用于监控外部设备的状态信息，并将外部设备的状态信息发送至外接模块及系统信息管理模块22；
需要说明的是，电视主机中有资源管理平台2和与资源管理平台2连接的外部设备接口4，外部设备接口4连接外部设备。具体的，资源管理平台2中包括的外部设备及交互管理模块25与外部设备接口4连接。也就是说，外接模块接口3同时与外部设备连接和外部设备及交互管理模块25连接，所以外部设备及交互管理模块25便于监控外部设备的状态信息。
一方面，根据各种外部设备的工作特征和交互方式可以将外部设备分为三种类 型：存储型外部设备、音视频型外部设备和交互式外部设备。下面是三种类型外部设备的定义和主要功能应用：
存储型外部设备是具备存储功能的外部设备，例如：USB移动存储设备等。电视主机和连接到电视主机的外接模块可以从存储型外部设备读取数据，例如照片进行显示、视频进行解码和显示，具备智能管理功能的外接模块可以安装和运行存储在存储型外部设备中的程序等，电视主机和连接到电视主机的外部模块可以将程序、视频、图片等存储到存储型外部设备。
音视频型外部设备是能够提供音视频内容输入的外部设备，例如：DVD播放器、机顶盒等。电视主机可以将音视频型外部设备输入的音视频经过处理后在电视主机或具备音视频输出功能的外接模块输出，还可以将音视频型外部设备输入的音视频经过编解码后进行存储。
交互型外部设备是能够提供人机交互功能的外部设备，例如：摄像头、鼠标、智能遥控器等。电视主机根据当前的工作状态，选择交互控制功能的处理方式。例如在语音操作场景，启动麦克风进行音频处理和操作；在手势操作场景，启动摄像头进行动作分析和操作。在电视主机本机显示输出状态下，各种交互控制信息完全按照电视主机设定控制模式进行操控；在外部模块显示输出状态下，通过内置的交互信息转换功能(主要是通过一个预先内置在电视主机或者在后台服务端的交互控制信息表来识别)将各种交互控制信息转换为外部模块能够识别的交互控制信息，并将转换后的交互控制信息通过HILINK发送到外部模块。
图12中列出了各种类型的外部设备需要使用的数据通路。
另一方面，根据电视主机对不同外部设备的管理模式，将外部设备分为注册类外部设备和非注册类外部设备。
注册类外部设备是指已经在电视主机的外部设备数据库中登记注册的外部设备。该类外部设备能够被电视主机自动识别，电视主机根据外部设备在电视主机的外部设备数据库中登记的信息，实现电视主机对该外部设备的控制或者该外部设备对电视主机部分资源的控制或者信息共享等功能，例如：电视主机可以接管在电视主机中已经注册过的外部设备的遥控信息等。
非注册类外部设备通常为首次接入电视主机的外部设备以及非通用类外部设备。电视主机允许该类外部设备进行电视主机注册，注册完成后提供相应的信息共享功能。
外部设备的注册流程和信息管理流程如图13所示。电视进入工作模式(电视 主机处于前台工作模式)后，动态监控外部设备接口4连接的外部设备，确定是否有新的外部设备启动或者接入，如果有新的外部设备启动或者接入，首先，获取该外部设备的状态信息，识别该外部设备是否为注册类外部设备，如果该外部设备为注册类外部设备，电视主机就加载预置的外部设备控制信息，这样电视主机可以按照该外部设备的控制信息控制该外部设备；如果该外部设备为非注册类外部设备，就提示电视主机是否注册该外部设备，在电视主机注册该外部设备的情况下，注册该外部设备，注册完成后按照注册类外部设备进行管理；在电视主机不注册该外部设备的情况下，电视主机以传统的独立外部设备控制方式进行管理。电视主机在对外部设备注册完成后，进入外部设备工作模式，此时电视主机处于后台工作模式，在一定条件下，外部设备和电视主机的工作模式可以互相切换；在电视主机不注册外部模块的情况下，外接模块处于传统的独立控制工作模式(外接模块控制主机内的资源，但是电视主机仍在原有的状态下工作)，电视主机处于后台工作模式，在一定条件下，外部设备和电视主机的工作模式可以互相切换。以上过程中，电视主机会监控和记录所有外部模块与电视主机的状态信息和控制信息。
主机内部资源模块21，用于监控主机内部资源模块21的状态信息，并将主机内部资源模块21的状态信息发送至外接模块及系统信息管理模块22。
需要说明的是，主机内部资源模块21需要将自身的状态信息发送至外接模块及系统信息管理模块22，以使得外接模块及系统信息管理模块22能够获取到主机内部资源模块21的状态信息。
具体的，如图3所示，主机内部资源模块21主要包括：直播电视资源单元211，音视频编解码资源单元212，音视频后处理资源单元213，视听资源单元214。以下是对主机内部资源模块中每一单元的详细说明。
直播电视资源单元211，用于实现模拟电视和数字电视的接收和解码，监控直播电视资源单元的状态信息，并将直播电视资源单元的状态信息发送至外接模块及系统信息管理模块22。
直播电视资源单元211的具体部件如图14所示。一般情况下，直播电视资源单元211包括：电视调谐部件2111、模拟电视解调解码部件2112和数字电视解调解码部件2113。电视调谐部件2111接收模拟电视信号或者数字电视信号，分别送入模拟电视解调解码部件2112或者数字电视解调解码部件2113处理，在接收模拟电视信号的情况下，输出解码后的音视频信息；在接收数字电视信号的情况下，输出解调后的音视频传输流信息。本申请实施例中直播电视资源单元211需要监控自 身的状态信息，并将自身的状态信息发送至外接模块及系统信息管理模块22，所以本申请实施例中的直播电视资源单元211除了上述部件外，还包括解调解码信息监控部件2114，该部件负责实时监控模拟电视解调解码部件2112和数字电视解调解码部件2113的工作状态信息，并将上述状态信息发送至外接模块及系统信息管理模块22。
音视频编解码资源单元212，用于实现音频和视频的编码和解码，监控音视频编解码资源单元的状态信息，并将音频视频编解码资源单元的状态信息发送至外接模块及系统信息管理模块22。
音视频编解码资源单元212的具体部件如图15所示。一般情况下，音视频编解码资源单元212包括：传输流解复用部件2121、多格式音视频解码部件2122、传输流复用部件2123和多格式音视频编码部件2124。传输流解复用部件2121接收经过的复用的传输流，并将该传输流进行解复用得到压缩的音视频码流，在将压缩的音视频码流进行传输至多格式音视频解码部件2122得到解压缩音视频码流。另外，多格式音视频编码部件2124接收原始音视频码流进行压缩编码处理得到压缩音视频码流，传输流复用部件2123压缩音视频码流用于将压缩音视频码流进行复用得到传输流。本申请实施例中音视频编解码资源单元212需要监控自身的状态信息，并将自身的状态信息发送至外接模块及系统信息管理模块22，所以本申请实施例中的音视频编解码资源单元212除了上述部件外，还包括编解码信息监控部件2125，该部件负责实时监控传输流解复用部件2121、多格式音视频解码部件2122、传输流复用部件2123和多格式音视频编码部件2124的工作状态信息(例如：音视频编码方式、码率、分辨率等)，并将上述状态信息发送至外接模块及系统信息管理模块22。
音视频后处理资源单元213，用于将非压缩的音频和视频进行优化，监控音视频后处理资源单元的状态信息，并将音视频后处理资源单元的状态信息发送至外接模块及系统信息管理模块22。
音视频后处理资源单元213的具体部件如图16所示。一般情况下，音视频后处理资源单元213包括：视频噪声检测处理部件2131、视频增强部件2132、视屏格式转换部件2133、音频后处理部件2134。视频噪声检测处理部件2131将接收到的解码后的解压缩视频码流进行降噪处理，然后传输至视频增强部件2132增大信号的信号强度，再将视频信号传输至视屏格式转换部件2133将视频码流的格式转换为可直接传输至显示屏显示的数据格式。同时，音频后处理部件2134接收解码 后的解压缩音频码流，并将该音频码流进行降噪、均衡等处理。本申请实施例中音视频后处理资源单元213需要监控自身的状态信息，并将自身的状态信息发送至外接模块及系统信息管理模块22，所以本申请实施例中的音视频后处理资源单元213除了上述部件外，还包括后处理信息控制部件2135，该部件负责实时监控视频噪声检测处理部件2131、视频增强部件2132、视屏格式转换部件2133和音频后处理部件2134的工作状态信息(例如：分辨率尺寸转换方式、帧率转换格式等、细节增强信息、对比度增强信息等)，并将上述状态信息发送至外接模块及系统信息管理模块22。
视听资源单元214，用于将音频与视屏输出，监控视听资源单元的状态信息，并将视听资源单元的状态信息发送至外接模块及系统信息管理模块22。
视听资源单元214的具体部件如图17所示。一般情况下，视听资源单元214包括：背光控制部件2141、主屏显示时序控制部件2142、附屏显示驱动部件2143、音频接口部件2144。背光控制部件2141和主屏显示时序控制部件2142用于显示传统的视屏内容，本申请在传统单一主屏显示基础上增加了附屏，附屏显示驱动部件2143主要用于显示系统信息、外部模块信息等内容，音频接口部件2144主要用于将接收到的音频码流传输至内置音响设备或外部音响设备。本申请实施例中视听资源单元214需要监控自身的状态信息，并将自身的状态信息发送至外接模块及系统信息管理模块22，所以本申请实施例中的视听资源单元214除了上述部件外，还包括显示信息监控部件2145，该部件负责实时监控背光控制部件2141、主屏显示时序控制部件2142、附屏显示驱动部件2143和音频接口部件2144的工作状态信息(例如：主屏显示数据、附屏显示数据等)，并将上述状态信息发送至外接模块及系统信息管理模块22。
外接模块及系统信息管理模块22，还用于获取主机内部资源模块的状态信息和外部设备的状态信息，并将主机内部资源模块的状态信息、外接模块的状态信息以及外部设备的状态信息发送至主机资源管理模块23。
具体的，外接模块及系统信息管理模块22自身已经用于监控外接模块的状态信息，同时主机内部资源模块21中每一单元将各自的状态信息发送至外接模块及系统信息管理模块22，外部设备及交互管理模块29将外部设备的状态信息发送至外接模块及系统信息管理模块22，所以外接模块及系统信息管理模块22能够获取到主机内部资源模块的状态信息、外接模块的状态信息以及外部设备的状态信息，并将这些信息发送至主机资源管理模块23。
进一步的，根据电视主机的主显示屏上显示的视屏码流的来源不同，可以将电视主机的播放模式分为三种：主机电视直播模式、外部设备输入模式和外接模块输入模式。
在主机电视直播模式下，电视主机利用主机内部资源模块(直播电视资源单元、音视频编解码资源单元、音视频后处理资源单元、视听资源单元、)依照传统直播电视功能进行显示和操控。此时，需要建立的数据通路如图18所示，依次通过直播电视资源单元211、音视频编解码资源单元212、音视频后处理资源单元213、视听资源单元214的数据通路。
在外部设备输入模式下，电视主机接收外部设备输入的音视频信息，利用主机内部资源中的相关单元(音视频编解码资源单元、音视频后处理资源单元、视听资源单元)实现外部设备中音视频信息的输出。此时，需要建立的数据通路如图12中所示，依次通过外部设备接口4、外部设备及交互管理模块25、音视频编解码资源单元212、音视频后处理资源单元213、视听资源单元214的数据通路，依次通过外部设备接口4、外部设备及交互管理模块25、音视频后处理资源单元213、视听资源单元214的数据通路的数据通路和依次通过外部设备接口4、外部设备及交互管理模块25、视听资源单元214的数据通路。
在外接模块输入模式下，电视主机接收外接模块输入的音视频信息，利用主机内部资源中的相关单元(音视频编解码资源单元、音视频后处理资源单元、视听资源单元)实现外部设备中音视频信息的输出。此时，需要建立的数据通路如图19中所示，依次通过外接模块接口3、音视频编解码资源单元212、音视频后处理资源单元213、视听资源单元214的数据通路，依次通过外接模块接口3、音视频后处理资源单元213、视听资源单元214的数据通路和依次通过外接模块接口3、视听资源单元214的数据通路。
电视主机的主显示屏的输出可以在三种模式中切换。切换方式可以是如图20所示的直达式切换。这种切换过程中，三种播放模式根据切换指令可以任意切换，主显示屏的播放画面直接由一种播放模式切换到另一播放模式。如果某种播放模式不在激活状态或者无效，系统会给出提示信息，屏蔽切换。这种切换方式有快捷、便利的优点。为了提供为用户提供更加直观友好的切换方式，本申请定义了一个主机信息预览画面，参见图21。主机信息预览画面是主机系统默认启动画面，具备一键返回功能(在任何状态下都可以通过返回指令返回该画面)。主机信息预览画面能够将主机直播信息、外部设备输入信息、外接模块输入信息在同一画面中呈现。 相应的，电视主机主显示屏的输出的切换方式还可以是如图22所示的返回式切换。这种切换过程中，每次切换时先返回主机信息预览画面，再根据切换指令切换至另一种播放模式。这种切换方式有直观、友好的优点。
在三种播放模式的情况下，电视主机的工作流程如图23所示，首先，启动电视主机，进入主机信息预览画面，选择进入主机电视直播模式、外部设备输入模式或外接模块输入模式；在选择进入主机电视直播模式或外部设备输入模式的情况下，电视主机切换至主机电视直播模式或外部设备输入模式，在接收到关机或待机命令后，检查是否有外接模块处于工作状态，如果有外接模块处于工作状态，则先关闭或待机外接模块，然后关闭或待机电视主机；在选择进入外接模块输入模式下，电视主机切换至外接模块输入模式，在接收到关机或待机命令后，提示关闭或待机的是主机还是外接模块，如果关闭或待机电视主机，则先关闭或待机外接模块，然后关闭或待机电视主机；否则关闭或待机外接模块，然后返回主机信息预览画面。
主机资源管理模块23，还用于分别根据外接模块的状态信息和外部设备的状态信息，对外接模块和外部设备进行识别和注册。
需要说明的是，主机资源管理模块23对外接模块的识别和注册过程可以参考图13所示的外部设备的注册流程和信息管理流程，主机资源管理模块23对外接模块的识别过程可以参考图6所示的外接模块的信息管理流程。主机资源管理模块23对外接模块的注册过程就是主机资源管理模块23对识别出的外接模块的模块类型、模块ID等信息登记至外接模块数据库的过程。
进一步的，若电视主机与后台服务器连接，则在图3的基础上，如图24所示，资源管理平台2的主机内部资源模块21还包括：网络资源单元215，资源管理平台2还包括：后台服务管理模块26。
