The present invention relates to a method for receiving and decoding an image data signal and a method thereof and, more specifically, a decoding method for image data and a device thereof preventing played images from being stopped or being broken by estimating and generating a frame which is lost with a normally received frame among adjacent frames when the frame is lost due to the failure of a signal receiving state. [Reference numerals] (AA) Start; (BB) No; (CC) Yes; (DD) End; (S500) Receive an image data signal; (S510) Check the quality of the signal; (S520) Extract compression parameters in a region in which a signal status is greater than a threshold level; (S530) Extract a variation between the compression parameters; (S540) Loss of the compression parameters is generated?; (S550) Estimate the compression parameters based on the variation; (S560) Generate an image frame |
