步骤S100、接收搭建无线通讯链路的请求信号，并根据所述搭建无线通讯链路的请求信号，在设定的时间内，发送搭建无线通讯链路的应答信号，表征已成功搭建无线通讯链路；Step S100, receiving a request signal for establishing a wireless communication link, and sending a response signal for establishing a wireless communication link within a set time according to the request signal for establishing a wireless communication link, indicating that the wireless communication link has been successfully established road;

本实施例中，也可以通过在智能电视上进行操作，生成发送的搭建无线通讯链路的请求信号。另外，如果穿戴式设备带有触控显示屏，则可以通过软件设置的方式在触控显示屏幕上设置icon，当用户触摸该icon时，启动步骤S100的处理过程。如果穿戴式设备的触控显示屏尺寸较小，难以在有效的显示范围内通过软件设置一icon，则可以通过在该穿戴式设备上设置一硬件触发开关，来产生步骤S100中的搭建无线通讯链路的请求信号。也可以通过复用穿戴式设备上的某一硬件开关比如待机键来启动步骤S100。当然，本申请步骤S100的启动并不局限于上述几种方式，比如也可以采用语音控制方式，来启动步骤S100中的搭建无线通讯链路的请求信号，在此不再赘述。该搭建无线通讯链路的请求信号可以包括源标识和目的标识，这两个标识可以通过穿戴式设备和智能电视的mac地址来实现，确保信号能够从源端和目的端之间进行传输。In this embodiment, the request signal for establishing a wireless communication link may also be generated and sent by operating on the smart TV. In addition, if the wearable device has a touch screen, an icon can be set on the touch screen by means of software settings, and when the user touches the icon, the process of step S100 is started. If the size of the touch screen of the wearable device is small and it is difficult to set an icon by software within the effective display range, a hardware trigger switch can be set on the wearable device to generate the wireless communication in step S100. link request signal. Step S100 can also be started by multiplexing a certain hardware switch on the wearable device, such as a standby key. Of course, the activation of step S100 of the present application is not limited to the above methods, for example, voice control may also be used to activate the request signal for establishing a wireless communication link in step S100, which will not be repeated here. The request signal for establishing a wireless communication link may include a source identifier and a destination identifier, and these two identifiers may be realized through the mac addresses of the wearable device and the smart TV, so as to ensure that the signal can be transmitted from the source end to the destination end.

本实施例中，一旦在设定的时间内返回了搭建无线通讯链路的应答信号，则表明穿戴式设备与智能电视之间的无线通讯链路已搭建成功，可以进行后续人机交互操作指令的传输。In this embodiment, once the response signal for establishing a wireless communication link is returned within the set time, it indicates that the wireless communication link between the wearable device and the smart TV has been successfully established, and subsequent human-computer interaction instructions can be performed transmission.

本实施例中，也可以每隔一定的时间，由穿戴式设备主动获取智能电视返回的搭建无线通讯链路的应答信号，如果获取到了，也标明无线通讯链路建立成功，否则，则标明当前时刻无线通讯链路未建立成功。当然，也可以通过智能电视每隔一定时间，主动向穿戴式设备发送搭建无线通讯链路的应答信号供穿戴式设备获取，如果获取到了，也表明无线通讯链路建立成功，否则，则标明当前时刻无线通讯链路未建立成功。In this embodiment, the wearable device can also actively obtain the response signal for building a wireless communication link returned by the smart TV at regular intervals. If it is obtained, it also indicates that the wireless communication link has been successfully established; The wireless communication link has not been successfully established at all times. Of course, the smart TV can also actively send a response signal for building a wireless communication link to the wearable device at regular intervals for the wearable device to obtain. If it is obtained, it also indicates that the wireless communication link is successfully established; otherwise, it indicates the current The wireless communication link has not been successfully established at all times.

在具体的应用实例中，步骤S100可能执行多次，直至无线通讯链路建立成功。In a specific application example, step S100 may be performed multiple times until the wireless communication link is established successfully.

步骤S102、获取经所述无线通讯链路传输的视频同步触发信号，并根据所述视频同步触发信号，实时对播放的视频信号进行视频编码处理后转化为无线视频信号，并经所述无线通讯链路实时发送；Step S102: Obtain the video synchronization trigger signal transmitted through the wireless communication link, and according to the video synchronization trigger signal, perform video encoding processing on the played video signal in real time and then convert it into a wireless video signal, and transmit it via the wireless communication link The link is sent in real time;

本实施例中，由于通过上述步骤S100的执行，已经完成了穿戴式设备和智能电视之间的无线通讯链路。该无线通讯链路可以基于wifi功能的无线路由、也可以基于短距离通讯的蓝牙模块（blue tooth，简称BT）来实现，详细请参加下述相关实施例。In this embodiment, due to the execution of the above step S100, the wireless communication link between the wearable device and the smart TV has been completed. The wireless communication link can be implemented based on a wireless router with a wifi function, or based on a short-distance communication Bluetooth module (bluetooth, BT for short). Please refer to the following related embodiments for details.

本实施例中，虽然已成功搭建无线通讯链路。但是，为了能够使智能电视对视频信号的本地播放切换到由另外一端的穿戴式设备进行播放，需生成一视频同步触发信号，通过所述无线通讯链路传输至智能电视。In this embodiment, although the wireless communication link has been successfully established. However, in order to enable the smart TV to switch from playing the video signal locally to being played by the wearable device at the other end, a video synchronization trigger signal needs to be generated and transmitted to the smart TV through the wireless communication link.

本实施例中，视频同步触发信号可以是根据在穿戴式设备的触控屏上进行的切换控件操作事件生成，比如某一软件设置的虚拟按钮，或者某一实体的硬件开关；当然还可以通过语音控制技术或者手势识别技术来实现。详细请参加下述实施例。In this embodiment, the video synchronization trigger signal can be generated according to the switching control operation event performed on the touch screen of the wearable device, such as a virtual button set by a certain software, or a hardware switch of a certain entity; Voice control technology or gesture recognition technology to achieve. Please refer to the following examples for details.

本实施例中，比如智能电视接收到该视频同步触发信号后，对其进行解析获知包头（如letv）和标识指令（010），确定出通讯的双方以及通讯的动作。In this embodiment, for example, after the smart TV receives the video synchronization trigger signal, it analyzes it to obtain the packet header (such as letv) and the identification command (010), and determines the communication parties and the communication action.

步骤S104、接收经所述无线通讯链路传输的、针对所述无线视频信号进行的操作事件，根据所述操作事件，同步播放所述播放的视频信号以及所述无线视频信号。Step S104, receiving an operation event for the wireless video signal transmitted through the wireless communication link, and synchronously playing the played video signal and the wireless video signal according to the operation event.

由于已经成功搭建了智能电视和穿戴式设备之间的无线通讯链路。因此，为了便捷地实现通过穿戴式设备即可同步控制智能电视和穿戴式设备上的视频，在穿戴式设备上生成一组常用的播放控制按钮，比如前进、后退、音量增、音量减，通过对这些按钮进行操作，生成对应的操控事件。穿戴式设备根据该操作事件可实现对智能电视和穿戴式设备上同步播放的视频进行同步操作。Since the wireless communication link between the smart TV and the wearable device has been successfully built. Therefore, in order to conveniently realize the synchronous control of the video on the smart TV and the wearable device through the wearable device, a set of commonly used playback control buttons, such as forward, backward, volume up, and volume down, are generated on the wearable device. Operate these buttons to generate corresponding manipulation events. According to the operation event, the wearable device can realize synchronous operation on the video played synchronously on the smart TV and the wearable device.

当然需要说明的是上述操作事件的生成也可以依赖于实体按键的触发或者语音识别技术，详细在此不再赘述。Of course, it should be noted that the generation of the above-mentioned operation events may also depend on the triggering of physical keys or voice recognition technology, which will not be described in detail here.

由此可见，本申请方法实施例一中，在成功搭建了穿戴式设备与智能电视之间的无线通讯链路之后；再根据视频同步触发信号，将所述智能电视播放的视频信号进行视频编码处理后转化为无线视频信号，经所述无线通讯链路无线传输到穿戴式设备上。当接收到经所述无线通讯链路传输的、针对所述无线视频信号进行的操作事件，根据所述操作事件，穿戴式设备同步播放所述无线视频信号，从而实现了利用穿戴式设备进行视频的同步播放，在穿戴式设备上实现重播、点播。It can be seen that, in Embodiment 1 of the method of the present application, after the wireless communication link between the wearable device and the smart TV is successfully established; then according to the video synchronization trigger signal, the video signal played by the smart TV is video encoded After processing, it is transformed into a wireless video signal, which is wirelessly transmitted to the wearable device through the wireless communication link. When receiving an operation event for the wireless video signal transmitted through the wireless communication link, according to the operation event, the wearable device synchronously plays the wireless video signal, thereby realizing the use of the wearable device for video Synchronized playback, replay and on-demand on wearable devices.
