Abstract:
1. A 3D encoding apparatus, comprising: an encoder that encodes an input image and generates and outputs a three dimensional stream including a basic stream and an extended stream including a plurality of image groups; a first virtual buffer that performs a buffer simulation of decoding the basic stream output from the encoder; a second virtual buffer that performs a buffer simulation of decoding the three dimensional stream output from the encoder; a first calculator that calculates a first delay value as a delay value of the basic stream for each image group based on a result of the buffer simulation performed by the first virtual buffer, a second calculator that calculates a second delay value as a delay value of the three dimensional stream for each image group based on a result of the buffer simulation performed by the second virtual buffer; and a setter that sets a specific delay value for each image group based on the calculated first delay value and second delay value, wherein the setter sets the specific delay value to a value not more than smaller one of the first delay value and the second delay value, the first virtual buffer and the second virtual buffer perform the buffer simulation for n+1th image group based on information about the specific delay value of the nth image group set by the setter in the basic stream and three dimensional stream.
