Abstract: This application provides example encoding methods and example encoders. One example method includes performing bit truncation on a to-be-encoded block when a bit rate control condition is satisfied. A first cost value corresponding to the bit truncation can then be calculated. The to-be-encoded block can then be predicted to determine a prediction residual of the to-be-encoded block when the bit rate control condition is satisfied. A second cost value corresponding to the prediction can then be calculated based on the prediction residual. The first cost value can then be compared with the second cost value to determine an encoded bit.

Abstract: Embodiments of this application provide a video transmission method, apparatus, and system, to reduce an end-to-end transmission delay of video data. The method includes: A transmit end obtains a first frame of image of the video data, where the first frame of image includes a plurality of sub-images, and the plurality sub-images include a first sub-image and a second sub-image; the transmit end performs layered encoding on the first sub-image to obtain a plurality of layers of bitstreams of the first sub-image; the transmit end sends the plurality of layers of bitstreams of the first sub-image to a receive end; the receive end decodes the plurality of layers of bitstreams of the first sub-image to obtain the first sub-image.
