Real-time screen sharing

Abstract

In implementations of the subject matter described herein, there are provided a method and apparatus for real time screen sharing. During the screen sharing of two devices, if a certain condition is satisfied for an image encoded by a first device and an image decoded by a second device, the first device pauses image processing images. If the pause time of pausing satisfies a certain length, a parameter associated with an image compression ratio is adjusted. After the first device resumes image processing, the adjusted parameter is used to encode a new image captured on the first device. According to implementations of the subject matter described herein, a transmission code rate during the screen sharing can be controlled according to the pause time of pausing image processing. The implementations of the subject matter described herein can reduce transmission latency of screen sharing, thereby effectively ensuring the user experience.

1 . A method comprising:
 in response to a first predetermined condition being satisfied for an image encoded by a first device and an image decoded by a second device, pausing image processing on the first device, the first device sharing a screen with the second device, the processing including one or more of capturing, encoding and sending of an image;   in response to a pause time of the pausing satisfying a second predetermined condition, adjusting a parameter associated with an image compression ratio; and   in response to the image processing on the first device being resumed, encoding a new image captured on the first device using the adjusted parameter.
