Video encoding/decoding apparatus and method |
摘要 |
Provided are a resolution varying video encoding/decoding apparatus and method are provided. The video encoding apparatus comprises a resolution varying encoder to perform an encoding operation using motion estimation and compensation on a current image having a first resolution and a current image having a second resolution according to a resolution control signal to generate a bitstream, and a controller to generate the resolution control signal for varying a resolution to the first resolution or the second resolution at a predetermined interval. The video decoding apparatus comprises an analyzer to analyze a bitstream composed of encoded data having a first resolution or a second resolution and to generate a resolution control signal corresponding to a resolution flag included in the bitstream, and a resolution varying decoder to perform a decoding operation using motion compensation on encoded data having the first resolution and encoded data having the second resolution according to the resolution control signal to generate a reconstructed image.
