Description

一种屏幕传输控制方法、装置、系统和相关设备 One kind of screen transmission control method, apparatus, systems, and associated equipment

技术领域 FIELD

[0001] 本发明涉及移动终端无线同屏技术领域,尤其涉及一种屏幕传输控制方法、装置、 系统和相关设备。 [0001] Technical Field The present invention relates to wireless mobile terminals with screens, and particularly to a method for controlling transmission screen, apparatus, systems, and associated equipment.

背景技术 Background technique

[0002] 移动终端无线同屏是在移动终端上新兴的屏幕共享技术,其借助于无线网络将移动终端上的多媒体内容推送到远端设备上进行展示。 [0002] The mobile radio terminal is in the same screen on the mobile terminal screen sharing emerging technology, a wireless network by means of the multimedia content on a mobile terminal pushed to show on the remote device. WiFi Display(WFD,无线显示)WiFi 联盟推出的技术方案,Miracast是WiFi联盟针对WFD技术实现产品的认证项目。 WiFi Display (WFD, Wireless Display) technology WiFi Alliance launched the program, Miracast WiFi Alliance is to achieve product certification program for WFD technology. Miracast 设备提供简化发现和设置技术,使得用户可以迅速在设备间传输多媒体内容。 Miracast device discovery and provides a simplified technique is provided, so that the user can quickly transferring multimedia content between devices. 该技术与认证项目由Wi-Fi联盟中的移动与消费性电子设备制造商及芯片厂商共同制定。 The technology and certification program jointly developed by the Wi-Fi Alliance in the mobile and consumer electronics equipment manufacturers and chip manufacturers. Miracast用户可以通过大屏幕电视浏览智能手机拍下的照片,通过会议室投影仪实时共享笔记本电脑屏幕,或者在平板电脑上收看家庭电视机顶盒的直播节目。 Miracast users can browse photos taken by smartphone big screen TV, laptop screen through real-time sharing conference room projector, or watch home TV set-top boxes of live programming on a tablet.

[0003] WFD 的底层技术是WiFi Direct (无线发现),Miracast 通过Wi-Fi CERTIFIED Wi-Fi Direct形成连接,因此无需接入任何Wi-Fi网络--Miracast认证设备内部具备连接功能,从而无线同屏设备的互相发现和设备连接遵循WiFi P2P(点对点)协议。 [0003] WFD Direct underlying technology is WiFi (wireless discovery), Miracast formed via WiFi CERTIFIED WiFi Direct, it is not necessary any WiFi network access authentication --Miracast internal equipment includes connectivity to the same radio screen devices discover each other and connect the device to follow the WiFi P2P (peer to peer) protocol.

[0004] WFD协议架构中包含两种类型的设备:发送端(Source)设备和接收端(Sink)设备,Source设备用于获取音视频等多媒体数据,经过编码后发送到Sink设备进行显示,常见的Source设备有手机、平板电脑、笔记本电脑等,Sink设备用于接收Source设备发送的音视频等多媒体数据并进行解码后播放,常见的Sink设备有机顶盒、电视和音箱等等。 [0004] Equipment WFD protocol architecture included in two types: the transmitting side (Source) and the receiver device (Sink) device, a device for acquiring the Source audio and video and other multimedia data transmitted to the display device Sink After coding, common the Source device mobile phones, tablet PCs, notebook computers, Sink devices for audio and video equipment to receive multimedia data sent by Source after decoding and playback, common Sink device set-top box, a TV and speakers, and so on.

[0005] WFD标准的一次一对一连接会话过程包括以下几个阶段:(DDevice Discovery (设备发现)阶段:Source/Sink设备发起设备发现动作,发现当前环境下具有WiFi Display功能的设备。(2)Service discovery (服务发现)阶段:发现设备WiFi Display相关的能力。(3)Device Select (设备选择)阶段:,用户选择一个发现的设备, 发起连接。(4) Connection Setup (连接建立)阶段:沿用WiFi Direct连接机制建立MAC 层连接。(5)Capability Negotiation(能力协商)阶段:Source/Sink 设备通过RTSP 消息协商、设置能力参数,包括音视频的编码格式、显示分辨率、音视频数据传输的端口号等。 [0005] WFD a standard one connection session comprises the following stages: (DDevice Discovery (device discovery) Phase: Source / Sink device to initiate operation of device discovery, discovery WiFi Display device having a function of the current environment (2. ) service discovery (service discovery) stages: the capabilities of the device WiFi Display-related findings (3) device select (device select) phase: the user select a device found, initiate a connection (4) connection Setup (connection establishment) stages: followed WiFi Direct connection mechanism established MAC layer is connected (5) capability negotiation (capability negotiation) stages:. Source / Sink device negotiates through the RTSP message, the ability to set parameters, including the encoding format of audio and video, display resolution, audio and video data transmission port number.

[6] SeSSion Setup(会话建立)阶段:维护会话连接以及进行会话过程中的参数调整。 [6] SeSSion Setup (session establishment) Stage: maintaining a session connection and to adjust the parameters of the session. (7) Data Transfer (数据传输)阶段:Source设备向Sink设备传输编码后的音视频数据。 (7) Data Transfer (Data Transfer) Phase: Source audio and video data to the device after the transfer encoding Sink device. (8) Tear Down (会话结束)阶段,Source设备或者Sink设备发起会话结束操作。 (8) Tear Down (session ends) stage, Source or Sink device device initiates a session end operation.

[0006] 但是,目前的Miracast技术仅支持一对一的数据传输,即一个Source设备向一个Sink设备传输数据,其网络拓扑结构示意图如图1所示。 [0006] However, current Miracast support only one data transmission, i.e. transmitting data to a Source device a Sink device that the network topology is shown in Fig.1. 实际应用中,例如视频电话、无线监控等应用场景中需要多对一的数据传输,即多个Source设备向一个Sink设备传输数据, 现有技术却无法实现。 In practical applications, such as video phone, a wireless monitoring application scenario requires a many data transmission, i.e. transmitting device to a plurality of Source Sink device data, the prior art can not achieve.
