摘要:
For a reproduction device in which a usable memory size has an upper limit, this invention discloses a novel structure of metadata, which can suppress the number of seeks of a CD or a DVD occurring at a time of reproduction of metadata of a moving image including a large number of scripts and hyper texts (HTML) each having a small data size, and the number of times of file request transmission/reception through a large number of networks. In the metadata of the moving image, in the case where access units AU#2 and AU#3 require EF#1, and access units AU#2 to AU#4 require EF#2, the EF#1 and the EF#2 are embedded in front of the AU#2, and a script in the AU uses a file name, a file identifier, or a virtual buffer offset in order to specify the EF to which reference is made. Embedding of a file and identification of the file are realized by causing the EF and the AU to have file identification information respectively and by specifying the file identification information from the script.

In the case where metadata refers to relevant content on a network, since the relevant content on the network can not be necessarily permanently held, it is desirable that a time limit for making reference can be set. Besides, in order to provide relevant content which can be referred to only in a limited period for promoting sales, or in order to provide relevant content which can be referred to only in a limited period such as, for example, Christmas Day every year for raising the entertainingness of the metadata, it is desirable that a reference time limit of the relevant content can be set. Then, in order to set an effective time limit of an access unit, a flag to specify the effective time limit and the effective time limit are described in each access unit.

A video encoding apparatus is provided with a resolution converting section, an encoding section, and a transmitting section. The resolution converting section enlarges or reduces a binary picture which represents the shape of an object. The encoding section encodes a binary picture reduced by the resolution converting section. The reduction ratio used by the resolution converting section is encoded, and the transmitting section transmits this encoded reduction ratio along with encoded data on the binary picture. The amount of encoded data produced from the encoding section is controlled by changing the enlargement/reduction ratio used by the resolution converting section.

In a preferred embodiment, an image-combining apparatus 212 includes a photographing unit 201, a composition unit 202, an input unit 204, a creation unit 206, an adjustment end instruction unit 208, and a display 211. An image of an object is photographed at S1010; a previously determined information-provision graphic is created at S1020; the information-provision graphic is combined with the photographed image at S1030, and is displayed on a display 211. On a preliminary composite image, the foot position of the object may be higher than the foot position of the information-provision graphic, or the information-provision graphic and the image of the object may not fit each other in size, or the object may be inclined. Then, position or the like of the object on the image may be adjusted.

摘要:
An attribute detecting apparatus of data signals obtains a block to which a mapped point belongs, for data signals divided into a plurality of blocks; sequentially repeats mapping processing in such a way that the mapped point belonging to the block is mapped to a similar region in the data signals previously allowed to correspond to the block (by setting an attribute detection position to an initial position of the mapped point and using the preceding mapping point as a new mapped point); and decides the attribute at the attribute detection position on the basis of position data of the mapping points obtained by the repeated mappings. An attribute detecting apparatus suitable for detecting the attributes of the fractal coded video signals can be realized.
