Abstract: A video is recorded on a recording medium so that a reproducing apparatus can faithfully reproduce an original color of the recorded video. An sRGB color space or an extended sRGB color space is specified as the color space of the video to be recorded. A signal processing unit generates a video signal corresponding to the specified color space. An encoding/decoding unit compresses the video signal in accordance with the MPEG4-AVC standard to generate a compressed video signal. A CPU generates a color space identifier including information indicating the color space specified and is configured so that an access unit including an SPS NAL unit in the compressed video signal includes an SEI NAL unit in which the color space identifier is stored. The video recorded on the recording medium includes the color space identifier having information for a color space of that video.

Random access is possible even if the GOP interval is lengthened.

Abstract: On a recording medium, stereoscopic and monoscopic specific areas are located one after another next to a stereoscopic/monoscopic shared area. The stereoscopic/monoscopic shared area is a contiguous area to be accessed both in stereoscopic video playback and monoscopic video playback. The stereoscopic specific area is a contiguous area to be accessed immediately before a long jump occurring in stereoscopic video playback. In both the stereoscopic/monoscopic shared area and the stereoscopic specific area, extents of base-view and dependent-view stream files are arranged in an interleaved manner. The extents on the stereoscopic specific area are next in order after the extents on the stereoscopic/monoscopic shared area. The monoscopic specific area is a contiguous area to be accessed immediately before a long jump occurring in monoscopic video playback. The monoscopic specific area has a copy of the entirety of the extents of the base-view stream file recorded on the stereoscopic specific area.

Abstract: Video frames from a sequence of video frames and corresponding audio are received and processed by a media player. A first portion of the sequence depends on fewer reference frames then a second portion of the sequence. The number of reference frames per frame is limited. The first and second portions of the sequence are treated differently. The first portion is received at a lower data rate, with greater security and processed with a more robust protocol stack than the second portion. The first and second portions may be stored in a single queue and/or separate queues. The first portion of frame data is utilized to compensate for lost frames by repeating and/or interpolating video frames. The media player constructs a local video frame and synchronizes corresponding audio content with it. The received, repeated and/or interpolated video frames are assembled into display order and decoded.

The encoding format used in any particular application is determined at encoding time from information provided by the archive system user. At encoding, the particular encoding scheme is selected to optimize a tradeoff between storage constraints and end use quality requirements.

Abstract: A rendering process for rendering an image frame and a postprocess for adapting the image frame to a display are separated. A rendering processing unit 42 generates an image frame sequence by performing rendering at a predetermined frame rate regardless of a condition that the image frame should meet for output to the display.

Since the rendering process and the postprocess are separated, the image frame sequence can be generated regardless of the specification of the display such as resolution and frame rate of the display.
