Abstract:
1. A video recording apparatus configured to record, onto a recording medium, a layered data structure containing a group of data elements, each of the data elements including video data or management information for the video data, and the layer data structure being separated into layers depending on the data elements, the apparatus comprising: an input unit configured to receive a plurality of channels of the video data, the plurality of channels corresponding to each other; an information generation unit configured to generate association information to be added to each of the data elements in at least two layers in the layered data structure such that one of the data elements in one layer of the layered data structure for one of the plurality of channels of the video data is associated with a corresponding one of the data elements in a corresponding layer of the layered structure for the other one of the plurality of channels of the video data; an adding unit configured to add the association information to each of the data elements in the at least two layers of the layered data structure; and a recording unit configured to record, onto the recording medium, the layered data structure in which the association information has been added to the each of the data elements; wherein the information generation unit is configured to generate the file name with a number including a first part and a second part, the first part being a number common to file names of a plurality of data files for corresponding ones of the data elements between the layered data structure for one of the plurality of channels of the video data and the layered data structure for the other one of the plurality of channels of the video data, and the second part being a number that differs among the file names of the plurality of data files for the corresponding ones of the data elements between the layered data structure for the one of the plurality of channels of the video data and the layered data structure for the other one of the plurality of channels of the video data.
