Embodiment Construction

[0097] In order to facilitate the understanding of the technical solution of the present application, firstly combine Figure 1A and Figure 1B The system architecture and devices applicable to the embodiments of the present application are described.

[0098] The embodiments of the present application are applicable to scenarios of cloud rendering services, such as cloud gaming scenarios. Cloud rendering business refers to the business of image rendering, encoding and compression on the cloud, and decoding and display on the terminal. Since the process of image rendering requires a lot of calculations and requires high device performance, by performing image rendering, encoding and compression on the cloud, and decoding and displaying on the terminal, users can experience high quality on terminals with low computing performance. Rendering screen to improve user experience. The embodiments of the present application are also applicable to scenarios of real-time streaming med...

Abstract

The embodiment of the invention provides a data transmission method, device and equipment, and the method comprises the steps that a terminal directly carries out the wireless screen projection protocol packaging of first data in an unvarnished transmission mode after receiving the first data from a server, obtains second data, and transmits the second data to wireless screen projection equipment.Since the terminal does not need to decode the first data and does not need to carry out secondary encoding on the first data when transmitting the first data to the screen projection equipment, thephenomenon of picture delay in the wireless screen projection process can be avoided, and the power consumption and the performance overhead of the terminal can be reduced.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a data transmission method, device, and equipment. Background technique [0002] The cloud rendering service represented by cloud games is an important service of the future 5G network. The data transmission process of the cloud rendering service is as follows: the cloud server renders the image, encodes and compresses the rendered image and sends it to the terminal. The terminal decodes the received encoded data to obtain a rendered image, and displays the rendered image. [0003] When experiencing the rendering service on the terminal, the experience is limited due to the small screen of the terminal. At present, the screen projection method can be used to project the display screen on the terminal to the screen projection device. Screen mirroring devices usually have a larger display, thus enhancing the user's visual experience. ...
