Embodiment Construction

[0053] In order to realize the scenario of many-to-one wireless on-screen conversations and to ensure that the processing capacity of the sink is utilized to the maximum in the many-to-one wireless on-screen network, in the embodiment of the present invention, the sink receives the service access request from the source , To allocate local idle resources of the corresponding service type to each source end, and to negotiate resources with the source end that has been connected through RTSP, to realize the establishment of a many-to-one wireless on-screen session.

[0054] The preferred embodiments of the present invention will be described in detail below with reference to 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 on-screen session is as follows:

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

[0057] In the embodiment of the presen...

Abstract

The present invention relates to the field of communications, and discloses a method and device for establishing a multi-to-one screen session. The method includes: receiving service access requests sent by at least two clients, and assigning corresponding services to the services requested by each client; The local idle resources of the service type, and then receive the service data sent by at least two clients, and present the service data of the corresponding client in the device based on the local idle resources of the corresponding service type assigned to each client. In this way, through the received service access request, local free resources of the corresponding service type are allocated to each client in real time, so that many-to-one wireless same-screen sessions can be realized, and resource negotiation can be carried out with the connected clients to maximize Utilize the processing capability of the receiving end to accept service access requests from multiple clients.

Description

Technical field [0001] The invention relates to the field of data processing, in particular to a method and device for establishing a many-to-one wireless on-screen conversation. Background technique [0002] Mobile terminal wireless screen is currently an emerging application on mobile terminals. With the help of wireless networks, multimedia content on mobile terminals is pushed to remote devices for display. Wi-Fi Display (WFD) is a technical solution launched by the Wireless Fidelity (WiFi) Alliance. The underlying technology of WFD is a portable hotspot (WiFi Direct). The mutual discovery and connection of wireless on-screen devices follow wireless point-to-point ( WiFi P2P) protocol. There are two types of equipment in the WFD protocol architecture: client (Source) equipment and sink (Sink) equipment; among them, the Source equipment is used to obtain audio and video data, which is encoded and sent to the sink equipment for display. Common Source equipment includes Mobile...
