摘要:
An inter-prediction method and a video encoding/decoding method using the inter-prediction method are disclosed. The video encoding method using inter-prediction includes: encoding a first picture that serves as a reference for random access; inter-prediction encoding a block included in a second picture, which is displayed before the first picture, by using a plurality of reference pictures; generating reference picture information representing whether a past picture, which is displayed before the second picture, is used as a reference picture for encoding the second picture; and transmitting the encoded first and second pictures and the reference picture information.
摘要:
A video encoding/decoding apparatus and method are disclosed. The video encoding/decoding apparatus includes: a video encoder for encoding a differential value between a quantization parameter value of a macroblock of a video and a quantization parameter value of a subblock in an extended macroblock based on additional information on the macroblock and the subblock; and a video decoder for reconstructing a differential value of a quantization parameter encoded by the video encoder, reconstructing a residual block based on a reconstructed differential value of the quantization parameter, and reconstructing the video based on the residual block reconstructed.
