Abstract: An image predictive coding method and an encoder. During a process of encoding a largest coding unit (LCU) in a tile of a current frame, a tile of the current frame is determined first, in which the to-be-predictive-coded LCU or a predicting unit (PU) is located, then, a tile of a reference frame is determined, where a position of the tile of the reference frame is the same as a position of the tile of the current frame, when a PU of the LCU is predicted, a reference pixel is selected from the determined tile of the reference frame, and when a predicted moving vector (PMV) of the PU included in the LCU is determined, the PMV of the PU is selected from the determined tile of the reference frame, which can prevent an error occurring in a tile from spreading to an entire frame of image.

Abstract: A video encoding method and device, so as to solve a problem that a long-term reference frame as a background frame is unavailable when an irrecoverable error occurs at an encoding end or a decoding end. The method includes: inputting a to-be-encoded video picture; encoding a current frame and specifying the current frame as a long-term reference frame; encoding each frame of the video picture with reference to the long-term reference frame and sending a data packet obtained after the encoding to a decoding end; and after a refreshing frame request sent by the decoding end is received, if it is determined that the long-term reference frame still serves as a reference frame for encoding, sending a non-IDR frame picture to the decoding end. The embodiments of the present invention are used for video encoding.
