Abstract

　複数の階層によって伝送される映像音声信号を、所定の復号化形式にしたがって復号化することで、映像音声信号出力する受信装置（１００）において、受信部（１０１）は、伝送路による受信状態への影響の大きな階層によって伝送される高解像度映像音声信号と、伝送路による受信状態への影響の小さな階層によって伝送される低解像度映像音声信号とを含む映像音声信号を受信する。記録部（１０２）は、受信された低解像度映像音声信号をメモリに記録し、検出部（１０３）は、受信される映像音声信号の受信状態を検出する。切替制御部（１０４）は、検出された受信状態に応じて、出力部（１０５）によって出力する映像音声信号を高解像度映像音声信号から、記録された低解像度映像音声信号に切り替える。
