摘要

A decoder performance management portion manages performance of a plurality of decoders provided in an AV stream reproducing apparatus. A display portion changes, in accordance with an instruction from the user, an output state of an image display frame on a screen of an output portion, and notifies it to a decoder management portion. The decoder management portion controls a decoder switching portion so that decoders used for decoding AV streams acquired by a communication portion (106) and a TV receiving portion are switched as appropriate, based on the notification from the display changing portion.
