A video-audio processing apparatus (11, 61), comprising: a video object recognizing portion configured to recognize a plurality of video objects on a moving image based on the video signal supplied thereto from an image pickup portion, and supplies a recognition result together with a video signal to a display control portion; the display control portion configured to cause the video signal comprising the plurality of video objects to be displayed; an object selecting portion (25, 74), comprising a person selecting portion, configured to: select the video object in response to a selection manipulation by a user, wherein the selected video object represents a person; produce object position information indicating a position, on a three-dimensional space, of the selected video object based on both the recognition result and the selection of the video object; and supply the resulting object position information to each of the sound source separation portion and the audio encoding portion; a sound source separating portion, configured to: extract an audio signal of the selected video object as an audio object signal using the object position information, the audio object signal being a signal of a voice of the selected video object; and extract a signal other than the audio object signal of the selected video object as a background sound signal from the audio signal; and an audio encoding portion configured to: encode the audio object signal and the background sound signal independently of each other, and multiplex the audio object signal and the background sound signal to produce an audio bitstream. a video object recognizing portion configured to recognize a plurality of video objects on a moving image based on the video signal supplied thereto from an image pickup portion, and supplies a recognition result together with a video signal to a display control portion;
