The present invention relates to a method and device for transmitting block division information for efficient image coding in a video compression technique for a high-definition security camera. To this end, the present invention obtains block division information from a bitstream, determines the division form of an image by computing and predicting omitted information if there is omitted information in the obtained information, and performs video decoding in the unit of a divided block.

Method and device for transmitting block division information in image codec for security camera

The present invention relates to a method and apparatus for performing encoding and decoding using a variably-sized quantization coefficient group, in quantization coefficient group encoding and decoding of video compression technology.

Video coding method and apparatus

A video encoding/decoding apparatus according to the present invention acquires motion vector refinement information, performs motion compensation on the basis of a motion vector of a current block, refines the motion vector of the current block using at least one or both of the motion vector refinement information and the output of the motion compensation, and performs motion compensation using the refined motion vector.

Method and apparatus for encoding/decoding video signal

The present invention relates to an image encoding and decoding technique for a high-definition video compression method and device for an omnidirectional security camera, and more specifically, to a method and a device whereby a differential motion vector is effectively transmitted, and an actual motion vector is calculated using the transmitted differential motion vector, and thus motion compensation is performed.
