In reference to FIG. 1, an encoding device 100 may include a picture partition unit 110, a prediction unit 120, 125, a transform unit 130, a quantization unit 135, a rearrangement unit 160, an entropy encoding unit 165, a dequantization unit 140, an inverse transform unit 145, a filter unit 150 and a memory 155.
As each construction unit shown in FIG. 1 is independently shown to represent different characteristic functions in a video encoding device, it may mean that each construction unit is configured with a separated hardware. But, as each construction unit is included by being enumerated as each construction unit for convenience of description, at least two construction units among each construction unit may be combined to configure one construction unit or one construction unit may be divided into a plurality of construction units to perform a function and such an integrated embodiment and separated embodiment of each construction unit are also included in a scope of a right of the present disclosure as long as they are not beyond the essence of the present disclosure.
In addition, some components may be just a selective component for improving performance, not an essential component performing an essential function in the present disclosure. The present disclosure may be implemented by including only a construction unit necessary for embodying the essence of the present disclosure excluding a component used only for performance improvement and a structure including only an essential component excluding a selective component used only for performance improvement is also included in a scope of a right of the present disclosure.
