Below with reference to the flow chart of Figure 10 and 11 establishment implemented in the DVD player of Fig. 9 method based on the moving frame data search information of captions is described.

In case loaded DVD in DVD player after, microcomputer 11 control servo units 7 make this DVD with constant rotary speed rotation.Then, the volume structure search pattern is set, to read the data (S10) that are stored in the volume structure zone.In the volume structure search pattern, optical pickup apparatus 2 is moved in the sector of LSN#256, be stored in to read in " first anchor point " " Primary Volume Descriptor sequence address " (S11).By using this address, read " Primary Volume Descriptor sequence " and from the field of " Primary Volume Descriptor sequence ", obtain " logical volume is unified the address " (logical volume integrity address).

Then, by use this address to read " logical volume unified " and from the field of " logical volume is unified ", obtain " set of file descriptor address " and afterwards with its storage (S112, S13).Then, read in " set of file descriptor " (S14), the title that is recorded in the All Files among the DVD, its size and beginning LSN are read in (S15) in the memory 12.Also read the management information of the numbering of the numbering that contains video title, its sprite that begins/finish LSN, title division (PTT) and son stream ID and it is stored in (S16) in the memory 12.

In case after finishing the reading of all required information, this DVD player enters an operator scheme, wherein, create as shown in figure 12 moving frame data search information or so-called sprite search list (S17) according to being stored in data in volume structure, file structure and the navigation data based on captions.

Figure 11 shows and creates the detail flowchart based on the sprite search list of the search of captions be used for the moving frame data.In sprite search list creation mode (S30), the numbering K of identification video title set VTS (integer value of Video Title Set Information VTS_0K_0.IFO " K ").Then,, created " video title set table (VTS table) " by numbering and starting position and the size of using this video title set, shown in Figure 12 a (S31).

From the first Video Title Set Information VTS_01_0.IFO, extract the numbering of PTT and the starting position and the numbering of sub-image data thereof, and be used for then creating " PTT table " (S32).The sub-image data that will belong to each PTT is arranged with form, promptly creates " sprite table ", shown in Figure 12 a.Then, create " sprite search list ", wherein, the sub-image data that belongs to each PTT is associated with corresponding moving frame data.Note that if multilingual is provided then for each clauses and subclauses, " sprite table " has a plurality of row and " sprite search list " has a plurality of row in video title.

The positional information of the moving frame data of reproducing simultaneously for multilingual with sub-image data, each clauses and subclauses of " sprite search list " have and the as many row of sprite channel number.In order to create the clauses and subclauses of " sprite search list ", at scan video title set object (VTS_0X_M.VOB, M=0,1,2......) time, son stream ID (the sub-stream of sub-image data bag be in the scope of 0x20～0x3F) and the mode of the positional information sub-image data (S33) of locating thereof of storage by the identification group in the row of " sprite search list ".Therefore, each sub-image data and positional information thereof are represented by the same index value of " sprite search list ".Specifically, the positional information of each sub-image data is represented by the logical block number of the starting position of the navigation group that belongs to video object unit VOBU (comprising sub-image data).The sequence number of each sprite clauses and subclauses also writes in the sprite search list shown in Figure 12 a.

In addition, the start and end time with each sub-image data of all obtaining by the header information of analyzing the sub-image data group writes in each corresponding sprite clauses and subclauses.

Replace the sprite search list of the hierarchy of establishment, it can create the chain type sprite search list shown in Figure 12 b from the video title set shown in Figure 12 a.Each sprite clauses and subclauses in the chain type sprite search list have sub-image data pointer " ^*Text (text) ", sequence number, the start and end time of the order of expression sub-image data, the index number that contains the unit of correlator picture, the index number of program chain of reproduction control information that contains the correlator picture and the field of index number that contains the video title set of correlator picture.All sprite clauses and subclauses by chain address " ^*Next (next one) " and " ^*Prev (previous) " link mutually forward and backward.

Each sprite can not be with image mode in the corresponding field of classification or chained list but store with mode word.For the storage of written form, by using character recognition algorithm being converted to character data (S34) as the sub-image data that the form of data has been stored among the DVD with bit map.Can adopt general optical character identification (OCR) method, for example based on the method for artificial neural net (ANN).In situation, need a training step to determine the power and position of ANN, and the output of ANN is mapped to the corresponding characters sign indicating number based on the character recognition algorithm of ANN.Specifically, prepare the training set of the binary digit map image of character sampling, and make it repeat self-organizing mapping graph (SOM), it is a kind of in the ANN model, and its function is the sampling of classification bit map character.Then, in identification step, determine the output of SOM mapped to a kind of mapping in the inhomogeneity of character code and be used for the position to shine upon a character classification device.

When it was employed, character picture was one by one extracted from the sub-image data of bit map picture.Each character picture is converted into black and white bit map picture, and is provided for the character classification device then.In this way, be character code with the captions image transitions of sub-image data and be stored in the memory afterwards and be used for showing.When captions are displayed on the screen, can show additional information by using character code (for example meaning of literal).

After the establishment of finishing " the sprite table " and " sprite search list " that be used for PTT, the address of two tables is pointed in storage in the corresponding row of " PTT table ", shown in Figure 12 a or 12b.

In case after finishing the scanning of all PTT among the video title set VTS, finish the creation operation of " sprite search list " by step S35, S36 and the formed circulation of S37.

The captions image of sub-image data can be without character conversion operation and direct each clauses and subclauses in the table that is stored as in the memory 12 shown in Figure 12 a or 12b and be used for showing.

Three pointer P1x, the P2x of Figure 12 a and P3x are used to point at starting point or the scope that playback duration appears at captions listed in the captions display window on the screen, as shown in figure 14.Specifically, P1x, P2x and P3x point to clauses and subclauses in PTT table, sprite table and the sprite search list respectively, and they are updated when video title is reset by microcomputer 11.
