Embodiment Construction

[0053] In order to realize the scenario of a many-to-one wireless same-screen session, and to ensure that the processing capability of the sink is maximized in the many-to-one wireless same-screen network, in the embodiment of the present invention, when the sink receives the service access request from the source , to allocate local free resources of the corresponding service type for each source terminal, and to conduct resource negotiation with the accessed source terminal through RTSP, so as to realize the establishment of many-to-one wireless same-screen sessions.

[0054] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings,

[0055] refer to figure 1 As shown, in the embodiment of the present invention, the process of establishing a many-to-one wireless same-screen session is as follows:

[0056] Step 100: Receive service access requests sent by at least two source terminals.

[0057] In the emb...

Abstract

The invention relates to the field of communications, and discloses a method and a device for establishing a many-to-one wireless one-screen session. The method comprises the steps of receiving service access requests sent by at least two clients, respectively allocating a corresponding service type of local idle source to the service requested by each client, then receiving service data sent by the at least two clients, and respectively representing the service data of the corresponding clients based on the corresponding service type of local idle source allocated to each client. In this case, the corresponding service type of local idle source is allocated to each client in real time via the received service access requests, so that the many-to-one wireless one-screen session can be realized; and resource negotiation with the connected clients can be realized, so that the processing capability of a receiver is furthest utilized to accept the service access requests of multiple clients.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and device for establishing many-to-one wireless same-screen sessions. Background technique [0002] Wireless co-screening of mobile terminals is an emerging application on mobile terminals at present, which pushes multimedia content on mobile terminals to remote devices for display by means of wireless networks. Wireless Network Display (WiFi Display, WFD) is a technical solution launched by the Wireless Fidelity (WiFi) Alliance. The underlying technology of WFD is a portable hotspot (WiFiDirect). The mutual discovery and device connection of wireless devices on the same screen follow the wireless peer-to-peer (WiFiP2P) protocol . There are two types of devices in the WFD protocol architecture: client (Source) devices and receiving end (Sink) devices; among them, Source devices are used to obtain audio and video data, and send them to Sink devices for display after encod...
