At first, the PSR14 820 as one of " player status registers (PSR) " comprises " auxiliary video stream number " field.The auxiliary video stream number is stored in " auxiliary video stream number " field.In this case, the auxiliary video stream number is used to specify and should presents which auxiliary video stream from each auxiliary video stream clauses and subclauses in the current STN that plays item shows.
" disp_v_flag " also is stored among the PSR14 820.In this case, " disp_v_flag " is the demonstration sign enabling or forbid of indication auxiliary audio frequency.For example, if sign " disp_v_flag " is configured to ' forbidding ' (0
b), then do not carry out demonstration, although auxiliary audio frequency still can be decoded by demoder 610b.Therefore, the user can not watch auxiliary video.On the other hand, if sign " disp_v_fag " is configured to ' enabling ' (1
b), then auxiliary video is by demoder 610b decoding and demonstration.Therefore, the user can watch auxiliary video via auxiliary video plane 620b.
The value of sign ' disp_a_flag ' can be changed by the order that generates from user's operation (UO), playback system or application programming interface (being designated hereinafter simply as API).
In the present invention, auxiliary video can reproduce together in company with presenting figure or text subtitle (abbreviating " PGTextST " hereinafter as).So, " PG TextST " (being called " PiP PG TextST " hereinafter) that storage unit (for example, the PSR2 shown in Fig. 8 B 810) is associated with auxiliary video with storage, be set.
In " PG TextST stream number " field, PG or TextST stream number (abbreviating " PG TextST stream number " hereinafter as) that storage is associated with main video.
PG TextST stream number be should be reproduced in the middle of each PG TextST stream clauses and subclauses that specify under the situation that auxiliary video do not show in a current STN table of playing PG or the information of TextST stream.In the situation that auxiliary video does not show, the sign " disp_v_flag " in the PSR14 820 is configured to ' forbidding ' or does not show auxiliary video stream during a current broadcast playback.
PG TextST stream number is to add the value that " 1 " obtains by the PG TextST flow identifier with definition in the STN table, and this will explain after a while.
On the other hand, in " PIP PG TextST stream number " field, PG or TextST stream number (abbreviating " PIP PG TextST stream number " hereinafter as) that storage is associated with auxiliary video.
PiP PG TextST stream number is the information that the PG that should reproduce in the middle of each PG TextST stream clauses and subclauses that specify under the situation that auxiliary video shows in a current STN table of playing or TextST flow.In the situation of auxiliary video stream demonstration, the signs " disp_v_flag " in the PSR14 820 are configured to ' enabling ' and show the auxiliary video stream of being indicated by PSR14 820 during current broadcast playback.
Value in being stored in " PG TextST stream number " field is in the situation of " 0xFFF ", means that playback system do not select PG TextST stream clauses and subclauses or do not have PG TextST stream.And the value in being stored in " PiP PG TextST stream number " field is in the situation of " 0xFFF ", means that playback system do not select PiP PG TextST stream clauses and subclauses or do not have PG TextST stream.
PG TextST stream number is to add the value that " 1 " obtains by the PG TextST identifier with definition in the STN table, and will explain after a while.
" disp_s_flag " indicates the sign that whether shows caption stream (PiP PG TextST stream or PG TextST stream).
If sign " disp_s_flag " is configured to ' forbidding (0
b) ', then do not show PG Text ST stream and PiP PG TextST stream.Yet, even " disp_s_flag " is configured to ' forbidding (0
b) ', also partly display graphics or text.For example, the compound object that presents the conversation area of figure or text subtitle can show that this does not illustrate in the drawings according to the value of intrinsic sign (" forced_on_flag ").
On the other hand, if sign " disp_s_flag " is configured to ' enable (1
b) ', then can show that the PG Text ST stream or the PiP TG TextST of appointment flow to the user.Be similar to PSR14 " disp_v_flag ", sign " disp_s_flag " can be operated (UO) or application programming interface (API) by the user and change.
Whether " PiP_PG_textST_valid_flag " indication " PiP PG TextST stream number " is effective.
" PiP_PG_textST_valid_flag " is used in reference to be shown in to use which kind of " PGTextST stream number " field when showing auxiliary video stream.
For example, if " PiP_PG_textST_valid_flag " is set to " 0
b", " the PG TextST stream number " field that then defines in PSR2 is used when showing auxiliary video stream.
On the other hand, if " PiP_PG_textST_valid_flag " is set to " 1
b", then use " the PiP PG TextST stream number " field that in PSR2, defines.If auxiliary video stream does not show that " PiP_PG_textST_valid_flag " is to not influence of optical record player then according to the present invention.In this case, can use the PG TextST flow identifier that is stored in " the PG TextST stream number " field that defines among the PSR2.
The value of " PiP_PG_textST_valid_flag " can be changed by navigation command or application programming interface (API).Here, navigation command or application programming interface (API) can be used when making user interface (UI) menu.Therefore, if on main video flowing, shown auxiliary video stream, then can optionally reproduce PiP PG textST stream (captions that are associated with auxiliary video stream) or PG textST stream (captions that are associated with main video flowing) according to customer requirements.
The PIP PG TextST flow identifier that is stored in the PSR2810 is controlled by the preference pattern of PiP PG TextST stream.
If auxiliary video stream shows that " PiP_PG_textST_valid_flag " in the PSR2 is configured to ' enable (1
b) ', the value that is stored in " PiP PG TextST stream number " field is not " 0xFFF ", and " disp_s_flag " in the PSR2 is configured to ' enable (1
b) ', then will show the PiP PG Text stream of determining by this preference pattern.
This situation is shown in Fig. 9 A, and wherein figure that is associated with auxiliary video or text 840 can show the figure or the text subtitle of main video 910 (but do not show) on auxiliary video 920.In some cases, shown in Fig. 9 B, figure that is associated with main video or text 930 are presented on the main video 910, and the figure that is associated with auxiliary video or text 940 can be displayed on the auxiliary video 920.
On the other hand, if auxiliary video stream shows that " PiP_PG_textST_valid_flag " in the PSR2 is configured to ' forbidding (0
b) ', the value that is stored in " PiP PG TextST stream number " field is not " 0xFFF ", and " disp_s_flag " in the PSR2 is configured to ' enable (1
b) ', then will show the PG Text stream of determining by this preference pattern.
This situation is shown in Fig. 9 C, and wherein figure that is associated with main video or text 930 can show on main video 910.
With reference to figure 8B, PG textST stream number and PiP PG textST stream number are stored in respectively in " the PG textST stream number " field and " PiP TextST stream number " field that is included among the PSR2.Simultaneously, whether " PiP_PG_textST_valid_flag " that has been assigned with 1 bit indicates PiP PG TextST effective.And " disp_s_flag " that be assigned with 1 bit indicates whether to show PiP PG TextST stream and PG TextST stream.
In above-mentioned PSR2, stored the broadcast state information of the captions that are associated with the auxiliary video that will be shown according to the reproduction management data.Captions comprise figure or text subtitle.Controller 12 captions that inspection will be shown according to the reproduction management data, and the playback state information that control is associated with the captions of checking out is stored among the PSR2.
