Abstract: According to one embodiment, a video processing apparatus includes: a structure computation unit that obtains a connection structure of HDMI compliant equipments connected with one another by HDMI (High-Definition Multimedia Interface) from physical addresses of the HDMI compliant equipments; and a video output unit that outputs video signal for displaying the connection structure of the HDMI compliant equipments connected by HDMI.

Abstract: This system includes a first video decoder which decodes source video data, an encoder which re-encodes a signal decoded by this decoder to rate-converted video data at a rate different from that of the source video data, and a digital AV recorder which records and plays back source audio data corresponding to the source video data, and the re-encoded rate-converted video data. This system also includes a second video decoder which decodes the rate-converted video data played back during recording of the source audio data and rate-converted video data, and an audio decoder which decodes the source audio data played back during recording of the source audio data and rate-converted video data.
