The disclosure provides an apparatus for encoding signals by using a 2-pass variable bit rate system. The apparatus includes a stream analyzing section that analyzes the input moving picture signals to create information required to calculate the degree of difficulty of encoding per unit time, an encoding degree-of-difficulty calculating section that calculates the degree of difficulty of encoding per unit time on the basis of the information created by the stream analyzing section, a recording section that records the input moving picture signals and the information on the calculated degree of difficulty of encoding per unit time such that they correspond to each other, and a decoding section that inputs the moving picture signals recorded on the recording section to decode the signals, and a bit rate calculating section that calculates a bit rate to be allocated to encoding at a second pass on the basis of the information on the degree of difficulty of encoding per unit time recorded on the recording section, and an encoding section that performs encoding at a second pass on the signals decoded by the decoding section according to the bit rate calculated by the bit rate calculating section. |
