Abstract: This application relates to the field of communications technologies, and provides a system and method for providing wireless network access, and an electronic device. The system includes a first electronic device and a second electronic device. The first electronic device receives a first operation of a user, where the first operation is used to share or project first data in the first electronic device to the second electronic device. The first electronic device establish a Wi-Fi direct connection to the second electronic device in response to the first operation; and receive a second operation of the user, where the second operation is used to enable a network sharing function of the first electronic device. The second electronic device receives the first data from the first electronic device; and performs data receiving and sending with a network side by using the network sharing function of the first electronic device.

Abstract: This application relates to the image processing field, and provides an encoding method and an encoder. The method includes: determining an encoding quantization parameter QP; precoding a to-be-encoded block by using the encoding QP to obtain encoding result information; adjusting the encoding QP based on the encoding result information; and performing real encoding on the to-be-encoded block by using an adjusted encoding QP. This can improve image compression performance.

Abstract: This application relates to the image processing field, and provides an encoding method and an encoder. The method includes: when a forcible bit rate control condition is satisfied, performing bit truncation of a spatial-domain branch and coefficient discarding of a frequency domain branch on a to-be-encoded block at the same time, calculating cost values respectively corresponding to the bit truncation and the coefficient discarding, and determining a final encoded bit based on the two cost values, so as to improve image decoding quality as much as possible while preventing bitstream buffer overflow.
