摘要： A sequence of digital images encoded according to a predictive format is decoded using encoded auxiliary data which is representative of at least part of the sequence of digital images. A current encoded image, received with at least one detected error, is decoded. The decoding includes applying an error concealment decoding on at least part of the current encoded image containing such a detected error to obtain a first decoded image. An item of information representative of reconstruction errors is obtained based upon a reconstruction confidence of the error concealment decoding for at least one pixel of the error-containing part of the current image. The encoded auxiliary data and the first decoded image are processed based upon the item of information representative of reconstruction errors to obtain corrected auxiliary data. The first decoded image is modified to obtain a second decoded image based upon the corrected auxiliary data.

摘要： An image processing method includes decoding encoded image data to generate a decoded image signal including a luma signal and a chroma signal. The method further includes detecting a condition that a reference field has a different parity from a current field and that the number of chroma pixels is vertically different from the number of luma pixels. The method further includes shifting a phase of the chroma signal in the reference field in a vertical minus direction according and a value of a motion vector in a vertical direction under the detected condition so that the reference field will coincide in phase of the chroma signal with a current field. The method also includes performing a motion compensation of the decoded image signal using the reference field.

摘要： A method of concealing errors in picture header information within H.263-encoded video compares current group-of-block frame identification (GFID) information to GFID information from the previous frame. If the GFID values are equal, the picture header information from the previous frame is used to decode the current frame. Otherwise, a selected parameter in the previous picture header information (for example, “picture type”) is altered and decoding proceeds with the altered picture header information. Preferably, only a portion of the current frame is initially decoded and validated prior to decoding the remainder of the frame. If the decoded portion is error-free, the decoding continues with the selected picture header information. If errors are found in the decoded portion, the picture header information is modified and the decoding process continues accordingly.
