A control information decoding section () decodes sets of control information contained in a stream. Further, a random access information analyzing section () carries out analysis of locations of random access points of media items contained in the stream, on the basis of the sets of control information. Still further, a management information generating section () generates management information for managing a plurality of random access points contained in the stream, on the basis of decoded versions of the sets of control information, which has been obtained by the control information decoding section (), and the locations of the random access points obtained by the analysis performed by the random access information analyzing section (). Then, the management information thus generated and the stream are recorded onto a storage medium (). This makes it possible to quickly start playback in performing random-access playback of a stream into which control signals are inserted at regular intervals.

An image signal composed of sequential frames is input to a 3-dimensional image creating apparatus, frame by frame. A controller () designates the presence/absence of reduction, the presence/absence of joining and 2D select. An image converter () creates image data in the format designated by the presence/absence of reduction and the presence/absence of joining. A 3D information creator () creates 3D information necessary for displaying the image as a 3-dimensional image by formatting the presence/absence of reduction, the presence/absence of joining and 2D select. A multiplexer () converts image data and 3D information in a predetermined format and outputs them to the outside. In this way, it is possible to make the image data for 3-dimensional display versatile and select an arbitrary viewpoint image efficiently.

A controller () designates whether images are integrated or not and image placement mode when integration is implemented. An image integrator () creates image data in a format designated by the presence/absence of integration and placement mode. A 3D information generator () generates 3D information necessary for 3D image display by formatting the presence/absence of integration and the placement mode. An encoder () encodes the image data created by image integrator () and generates coded data. A multiplexer () converts the encoded data generated by encoder () and the 3D information created by the 3D information generator into a predetermined format and outputs the result to the outside. This arrangement enables image data for 3D display to be versatile.

Image data creation device and image data reproduction device for reproducing the data

A controller () designates the method of integrating viewpoint images. An image integrator () creates an integrated image by placing individual viewpoint images in appropriate positions. A 3D image control information creator () creates 3D image control information by formatting the placement mode of individual viewpoint images and various 3-dimensional image characteristics. An encoder () encodes integrated image data. A multiplexer () multiplexes the coded data and the 3D image control information and outputs them. A filename deciding unit () decides the name of a file when multiplexed data is recorded as a file. A storage directory deciding unit () decides the directory in which a file to be recorded is stored. A file creator () records a file with the decided filename under the decided storage directory. Thus, the distinction between 3-dimensional display image data and 2-dimensional image data can be clarified.

This invention provides a stereoscopic-vision image processing apparatus, a stereoscopic-vision image providing method, and an image display method that are capable of managing specification of display unit on which a stereoscopic-vision image is desired to be displayed as accessory information (assumed display information). The assumed display information includes a type and a display size of the display unit on which a stereoscopic-vision image is desired to be displayed. This allows an appropriate stereoscopic-vision image to be obtained by specifying a type or a display size of the display unit that is desired to be displayed with them being combined with the stereoscopic-vision image and scaling the stereoscopic-vision image up or down, in display of a stereoscopic image, in accordance with the type or the display size of the display unit.

A multimedia information recording device is used for efficiently recording multimedia information () file storage area () on a recording medium (). From the multimedia information given to the device, a data body DB and control information (HD and FD) are created and given to a file storage area writing section () where the data is written in parallel at a time on a free cluster in the file storage area. In the free area of each cluster where the data is written, dummy data is packed by a dummy data adding section () to absorb the difference between the first position of a cluster and the first position of the data in the cluster. Thus, data rewriting to eliminate this difference is avoided. Information for connecting plural clusters where data is written is created by a multimedia information file creating section (), and the multimedia information is recorded in a multimedia information file on the recording medium.

A managing method for a multimedia file includes the steps of: generating index information including a source identifier expressing a source having one or more of management units associated with the multimedia file as a title frame, positions of a leading frame and tail frame of the title frame in the source, and a position of a reference frame for decoding the leading frame; and recording the index information onto a recording medium, attaching the index information to the multimedia file. The managing method for a multimedia file may include the steps of: causing a user to specify one or more of the management units associated with the multimedia file as a title frame; generating index information in which a bit stream obtained by encoding a specified title frame is embedded, and recording the index information onto a recording medium, attaching the index information to the multimedia file.

If received coded video-data includes data with an error unable to be decoded or data disagreeing with ITU-T recommendation H.261 (e.g., the number of bits per frame exceeds the limit defined by the recommendation), it must be stored with due countermeasures taken against error and inadaptable data, which allows the stored data to be effectively reproduced. Received coded video-data is decoded by a transmission-line decoding portion and divided into frames by a data dividing portion. Thereafter it is decoded by an information-source decoding portion and then intraframely encoded by a intraframe coding portion. According to a signal from a bit-counting portion showing that the number of bits in one frame of coded video-data exceeds the limit defined by ITU-T recommendation H.261 or anomalous signal of a frame image decoded by the information source decoding portion, a frame-processing control portion decides how to store each frame and controls a storable data transfer portion to select intraframe-coded data and transfer the selected data to a data storage.
