Claim:
1. A video decoding apparatus, comprising: a decoder configured to decode a bitstream received from a video encoding apparatus to an inverse-quantization and inverse-transform unit configured to inversely quantize the quantized transformed residual block into a transformed residual block and inversely transforms the transformed residual block to generate a residual block; an inter prediction unit configured to an adder configured to reconstruct the current block by adding the reconstructed prediction block and the residual block generated by the inverse-quantization and inverse- transform unit, wherein the inter prediction unit is configured to wherein the inter prediction unit is configured to select, as the first candidate predictive motion vector, the first valid motion vector found by sequentially scanning the adjacent blocks in an upward direction, wherein the adjacent blocks are located at the left side of the current block, and the adjacent blocks include at least one pixel adjacent to the current block.
