Abstract: Video coding/decoding can improve the uniformity of pixel strings and provide for increased coding and decoding efficiency. String length information of a current string from a bit stream is decoded. Based on the string length information and a determined string length resolution (SLR) of the current string a string length of the current string is determined. By using the SLR as a basis for dividing and decoding the pixel string, the length of the pixel string in a coding block can be limited to a multiple of the SLR, which improves uniformity of pixel strings, so that a decoder end can perform decoding with memory alignment, thereby improving decoding efficiency of the pixel strings.
