Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention.

[0030] First, the terms of the embodiments of the present invention are explained.

[0031] Data Rate: Refers to the data flow used by the encoded video to represent the content per unit time, also known as the bit rate. The larger the code rate, the better the picture quality of the video. The code stream type refers to the type obtained by dividing the code stream according to the size difference of the code stream.

[0032] The method for playing a video on a projection screen according to an embodiment of the present invention is introduced below.

[0033] The video projection screen playback method provided by the embodiment of the present invention may be applied to a first device ...

Abstract

The embodiment of the invention provides a video projection screen playing method, device, and system, and equipment. The video projection screen playing method is applied to first equipment with a video projection function and comprises the following steps: acquiring a specified equipment parameter of second equipment serving as a projection screen receiver, wherein the specified equipment parameter is an equipment parameter influencing a code stream type supported by the second equipment; obtaining a mapping relationship between the specified equipment parameter and an alternative code stream type, wherein the alternative code stream type is a code stream type supported by equipment with the specified equipment parameter; selecting a code stream type from the obtained mapping relationship as a target code stream type; and providing the to-be-projected screen video belonging to the target code stream type for the second equipment. According to the scheme, the failure frequency of video screen projection playing can be reduced.

Description

technical field [0001] The present invention relates to the field of video technology, in particular to a method, device, device and system for playing video on a projection screen. Background technique [0002] With the development of Internet and video technology, video projection is widely used in life and work. In related technologies, in order to realize screen projection playback, after determining the second device as the receiver of the screen projection, the first device with the video projection function provides the video to be projected that belongs to the predetermined code stream type to the second device. the second device, so that the second device plays the video to be projected. For example, the first device may be a mobile terminal, and the second device may be an Internet TV. [0003] However, the inventors have found that: due to the wide variety of second devices, there is a problem of high failure rate of video projection and playback when using rela...
