Patent ID: 8244052

Claim:
A video coding method using a hardware encoder computer device, comprising the steps of: retrieving an elementary block of data to be encoded; calculating a predicted displacement of the encoded block by using displacements of adjacent encoded blocks and retrieving a predicted block of data corresponding to the predicted displacement; partitioning the encoded block and the skipping predicted block into encoding partitioned sub-blocks and predicted partitioned sub-blocks, and calculating the detection likelihood ratio Λ by using those partitioned sub-blocks; and calculating the decision threshold η and in the meantime using the decision threshold n and the detection likelihood ratio Λ to determine whether the encoded block is an image data to be skipped; if yes, terminating the coding of the present block; otherwise the detecting is failed, and enabling the hardware encoder computer device to move on to the next step to further execute a coding operation, wherein the decision threshold η is computed by using the following formula: η=κ· Q step ( QP ), where κ is a dynamic decision parameter, QP is a quantization parameter which is designated by the hardware encoder computer device, and Q step is a quantization step parameter which is a function of the quantization parameter.
