2. Description of the Related Art In recent years, images, video, audio, sound, CG (C
International standardization of data encoding such as omputer graphics) has been promoted, and multimedia has been rapidly advanced. In particular, ISO / IEC14496 (MPEG (Moving Pictur
e Experts Group) -4) is proceeding with international standardization (standardization) of multimedia coding systems (compression formats).

[0003] In the above standard, in addition to the conventional video / audio data encoding, it is possible to define the spatial / temporal arrangement of each medium, and this is called a scene description. Each medium is called an object.

As a method of the scene description itself, VRML is used.
BIFS (BInary Format for BIFS) that has been extended and binarized based on (Virtual Reality Modeling Language)
Scene description) has been adopted. The BIFS binarization method is omitted.

Also, apart from this scene description, an object descriptor (hereinafter referred to as OD)
Data indicating the attribute of each object is added. Attributes are media attributes (video, audio, image, etc.), copyright holder information, QoS information (Quality of Servi
ce), content rating information, and the like. These attributes themselves are included in the OD as one descriptor each.

FIG. 14 is a diagram for explaining an example of a bit stream in the MPEG-4 encoding system.

In FIG. 14, reference numeral 1401 denotes an initial object descriptor which stores properties of the entire bit stream (such as a profile of the bit stream). Reference numeral 1402 denotes a BIFS stream, which stores scene information.

Reference numeral 1403 denotes an object descriptor (hereinafter referred to as OD), which describes the attributes of the subsequent objects. In this example, two ODs (OD1 (14
03) and OD2 (1406)).
In the OD, a plurality of elementary stream descriptors (hereinafter, referred to as ESD (1404, 1407)) indicating attributes of each media stream (hereinafter, referred to as an elementary stream (hereinafter, referred to as ES)) can be described. Has become. ES in each OD is designated as ES1 (1
409, 1411, 1413, 1415), ES2 (1

Free syntax. RA (Registr
Only the IPMP system type number registered with the ATION Authority is described.

The OD, ESD, and IPMP descriptors described above must be placed at the head of each stream before each elementary stream as shown in FIG. However, each descriptor can be added, deleted, or changed by inserting an update command in the middle of the stream.

In practice, each elementary stream is packetized and becomes a Sync Layer Packet (SL Packet). An SLConfig descriptor (SLConFig ((1405, 1408))) is also attached to each ESD to describe the structure of this SL Packet.

On the other hand, the IPMP information itself described by the IPMP descriptor can be added with an ES for IPMP (IPMP_ES) by linking with the ID.

FIG. 15 is a view for explaining an example of a bit stream to which an ES for IPMP is added.

In FIG. 15, IPMP1 (1501)
And IPMP2 (1502) are ES1 and E2 respectively.

Reference numeral 1603 denotes a descriptor ID, and reference numeral 1604 denotes IPMPS_Type, which indicates the security type number as described above. 1
Reference numeral 605 denotes an option field, into which data accompanying IPMP can be appropriately inserted. The syntax in this optional field is free.

FIG. 17 is a diagram showing an example of a system encoder for generating the bit stream.

In FIG. 17, reference numeral 1701 denotes an object descriptor generator, which appropriately generates the above-described descriptor according to the properties of the bit stream.

Reference numeral 1702 denotes a media encoder which actually encodes data such as video data and audio data. Reference numeral 1704 denotes a BIFS encoder, which binarizes the scene information. Reference numeral 1703 denotes an IPMP controller, which controls an encoder according to the IPMP descriptor and the IPMP_ES (for example, controls execution of an encryption process).

An update controller 1705 inserts a command for updating properties such as OD, ESD, and IPMP descriptor as needed. Reference numeral 1706 denotes a multiplexer which converts the above-described descriptor and media stream into one SL.
This is the part that is multiplexed as a packet.

FIG. 18 is a diagram showing an example of a system decoder for decoding the bit stream.

In FIG. 18, reference numeral 1801 denotes a demultiplexer which discriminates each descriptor and ES. 18
Reference numeral 02 denotes a descriptor parser, which determines the type of the descriptor based on the tag information, decodes the content of each descriptor, and sets the content in each unit as appropriate.

Reference numeral 1805 denotes an IPMP controller.
The reproduction of the media is controlled according to the information of the IPMP descriptor and the IPMP_ES. For example, if the data is encrypted, the data is transferred to the media decoder after decrypting the code. Reference numeral 1806 denotes a synchronization control unit that controls synchronization between media.

The method of transferring data from the encoder side in FIG. 17 to the decoder side in FIG.
In the case of transmission over a network, it is general that all data are transmitted and received as one bit stream in the same session.

On the other hand, as the contents become more complicated and more sophisticated as in the MPEG encoding method, the cost of the standardization work is collected from the organizations and companies involved in the standardization work by paying a royalty for the technology. The movement is becoming active. In fact, a patent licensing company has been established for MPEG-2, and royalty fees for important patents related to MPEG-2 are charged by each company for a uniform amount for each product. A codec manufacturer or the like becomes a licensee to collectively license patents related to MPEG-2, and pays royalties.

[0029]

SUMMARY OF THE INVENTION However, MPE
Unlike MPEG-2, whose use is relatively limited to broadcasting and digital storage media, G-4 allows a great number of tool combinations.

For example, in the Simple Profile, when the coding rate is 384 kbps or less, an I-VOP (Intra-coded VOP (Video Object P
lane)), P-VOP (Predictive-coded VOP) coding, AC / DC
Using a tool such as prediction, encoding is performed with the shape limited to a rectangle. Core Profile has a coding rate of 2 Mbps or less, a tool for encoding arbitrary shapes, a tool for encoding arbitrary shapes, and a tool for B-VOP (Bidirectionally Predictive-coded VO
P) coding has been added. Therefore, MPEG-
The four-encoding scheme is very complicated.

In MPEG-4, the use of tools varies, so that a patent licensing method such as MPEG-2 is unfair. In addition, unfairness also occurs in a method of setting an amount for each profile or setting an amount by determining a combination. For example, if the coding rate is 1Mbps and Simpl
Even if you only use the e Profile tool, you must bear the royalty of arbitrary shape coding.
