Abstract: A data coding method includes determining a length of a current first bit-rate-control-unit data frame in to-be-transmitted data, and the length of the first bit-rate-control-unit data frame is less than or equal to a length of a group of pictures (GOP) data frame. The method also includes determining a first target bit rate of the first bit-rate-control-unit data frame according to the length of the first bit-rate-control-unit data frame, a target bit rate of the to-be-transmitted data, and a frame rate of the to-be-transmitted data and, when a first difference value between a real bit rate of a second bit-rate-control-unit data frame and a second target bit rate of the second bit-rate-control-unit data frame is greater than zero, adjusting the first target bit rate according to the first difference value, and coding the first bit-rate-control-unit data frame according to the adjusted first target bit rate.

Abstract: In a video encoding method, a to-be-encoded video is obtained. The video includes at least two video frames arranged in sequence. A quantization parameter and a quantization parameter threshold of an ith video frame is calculated, where i is a positive integer greater than or equal to 2. A coding resolution of the ith video frame is determined according to the quantization parameter and the quantization parameter threshold. The coding resolution is a first coding resolution in a case that the ith video frame is sampled, and the coding resolution is a second coding resolution in a case that the ith video frame is downsampled. Then the ith video frame is encoded at the coding resolution.

Abstract: A video encoding method is provided. The video encoding method includes: obtaining a to-be-coded video frame; determining a current encoding mode according to current coding information and/or image feature information of the to-be-coded video frame; processing the to-be-coded video frame according to the current encoding mode to generate a current coded video frame; obtaining a current reference frame corresponding to the current coded video frame based on the current coded video frame being an inter frame; obtaining a corresponding processing reference frame according to resolution values of the current reference frame and the current coded video frame; and encoding the current coded video frame according to the processing reference frame to generate first coded data.

Abstract: This application discloses a link decision-making method, applied to a link decision-making system including first and second user equipment that are in a Voice over Internet Protocol (VoIP) call status, a transit server, and a decision-making computing device. A first link directly connecting the two user equipment and a second link that transits by using the transit server exist between the two user equipment. The decision-making computing device is responsible for making, according to a link quality score of a current sending link between the first and second user equipment, a decision about using the first link or the second link as a subsequent sending link of the first user equipment. According to the link decision-making method provided in this application, it can be ensured that a better link can be selected to transmit a data stream of VoIP, thereby improving the quality of service (QoS) of the VoIP.

Abstract: The present invention provides a hybrid-resolution encoding and decoding method. The method includes performing full-resolution standard coding on an I frame that adopts only intra-frame coding in a video frame sequence, and performing frame reconstruction to obtain a reconstructed frame of the I frame; performing down-sampling on the reconstructed frame of the I frame to obtain a first sampling image of the reconstructed frame of the I frame; performing down-sampling on a non-I frame in the video frame sequence to obtain a second sampling image of the non-I frame; performing standard coding on the second sampling image of the non-I frame by using the first sampling image of the reconstructed frame of the I frame that corresponds to the non-I frame as a reference frame; and sending a video code stream that includes the full-resolution standard coded I frame and the standard coded non-I frame.
