<p>Video encoding and decoding methods and apparatuses are provided which are effective for error correction and error concealment in an error-prone environment. The video encoding method includes determining (S1210) an encoding operation to encode raw video among a frame encoding operation, a top/bottom field encoding operation, and a left/right field encoding operation based on at least one characteristic of the raw video; and generating (S1230) a bit stream by adaptively performing the encoding operation that is determined to encode the raw video. Further, video may be divided into frame pictures, top/bottom field pictures and left/right field pictures, and encoded accordingly. Therefore, a compression rate can be increased, and error correction and concealment can be effectively performed on a lost field by using a normally received field.</p> |
