[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an object generating apparatus and an object generating program for converting media data composed of video data, audio data, etc. into an object so as to be handled uniformly regardless of the format method, the type of storage medium, and the like.
[0002]
[Prior art]
Generally, in broadcast stations, various media data such as video and audio are processed by various devices to produce programs. Also, practical application of various metadata describing the characteristics (encoding method, data structure, format, etc.) of the media data has begun to be studied.
[0003]
Applications of adding this metadata to media data and using it as media data (program) search information are being studied.
[0004]
[Problems to be solved by the invention]
However, there is no method for handling media data and metadata generated in a plurality of formats in a unified manner, and there is a problem that confusion occurs for those who handle media data.
[0005]
An object of the present invention is to provide an object generation device that solves the above-described problems of the prior art and generates an object that can uniformly handle media data, metadata, and playback devices that handle media data.
[0008]
[Means for Solving the Problems]
  In the following explanationThe media data is an image stream, an audio stream, text data, editing information, and the like. The metadata of the media object is data indicating attributes related to the media data. For example, the type of the media data object (hereinafter referred to as a media object), the image size, the data structure, the required communication rate, etc. is there. An application program interface (hereinafter referred to as API) plays a role of processing various requests from outside on various platforms (OS) and responding to the outside.
[0009]
The metadata of the device object (hereinafter referred to as a module object) is data indicating the specifications of the conversion or playback display device. For example, when the device is a display device such as a monitor, the metadata of the displayable media object is displayed. This is data relating to type, encoding type, image vertical and horizontal width, color mode and bit mode. The API functions to process various requests from the outside and respond to the outside on various platforms (OS).
