Definitions
- Recording medium reproducing apparatus, recording method, program, reproducing method
- the present invention relates to a recording medium on which a digital stream in which an animal stream and a graphics stream are multiplexed is recorded, and a reproducing apparatus for reproducing the digital stream.
- the present invention relates to a technique for obtaining a reproduced video by separately decoding a moving picture stream and a graphics stream by a reproducing apparatus and synthesizing the video-graphics obtained by the decoding.
- a graphics stream is an array of PES packets.There are two types of PES packets: those that store control information and those that store graphics data, which is the graphics itself. .
- the control information is arranged before the graphics data, and a single graphic display is realized by a pair of the control information and the graphics data.
- the playback device sequentially reads the control information and the graphics data, decodes the control information, decodes the graphics data, and outputs the uncompressed graphics obtained by the decoding. Display at the desired display timing according to the result of decoding the control information.
- Graphics have a time interval of 2-3 seconds, like subtitles in a movie If it is updated by, there is no problem even if the graphics resolution is slightly higher and the decoding period is longer. However, when using graphics for amusement applications, there is a demand for a shorter display interval for graphics.
- the purpose of the amusement is to add a unique movement to the graphics showing the dialogue of the characters, to draw the viewer's attention, or to change the color flashy, thereby giving the viewer's intention. Is to poke.
- the demand for realizing such graphics displays is particularly strong from the production sites of video content with a wide variety of colors.
- the process of decoding and displaying the graphics is performed in a short period of one display period (1 / 29.97 sec for NTSC). Each time elapses, it must be done. Repeating the decode display of the graphics every time one display period elapses is a huge burden, and the playback device hardware that is supposed to spread at low cost is as follows: It is difficult to achieve in a fast pack.
- the above-mentioned dynamic motion and color change can be realized by composing graphics in advance for each frame of a moving image and treating the graphics as a part of the picture of each frame.
- the method of combining graphics into frames one by one in advance lacks the flexibility of selectively displaying graphics according to the language setting and display setting of the playback device. Therefore, as long as this method is adopted, the prospects for the future cannot be seen.
- An object of the present invention is to provide a recording medium capable of moving graphics with smoothness like a moving image.
- the purpose of the above is to record a digital stream obtained by multiplexing a video stream and a graphics stream, and the graphics stream is an array of packets. ,.
- the control information indicates that the graphics data existing in front of itself in the bucket string is combined with the moving image stream at a predetermined timing and displayed. Achieved.
- the control information indicates that display is to be performed using graphics data existing ahead of itself. Therefore, the playback device can be controlled to change the display position of the graphics or change the color of the graphics only by sending only the control information indicating the new coordinates to the playback device.
- the essence of the present invention is a technique suitable for processing for displaying the same graphics while changing its position at high speed.

- the broken line in the figure indicates the DS to which the functional segment in the third row belongs.
- the playback device can compose graphics for one screen by reading the multiple function segments constituting the DS from the BD-ROM.
- the first stage Epoch refers to one period that has continuity of memory management on the playback time axis of the AVC lip, and a data group assigned to this period.
- the memory assumed here is a graphics plane for storing one screen worth of graphics, and an object buffer for storing decompressed graphics data. is there. Continuity in memory management for these means that flushing of these graphics planes and object knockers does not occur during the period of this Epoch, and there is a certain The erasing and redrawing of graphics is performed only within the rectangular area. (* Flush here means clearing all the stored contents of planes and knockers.) .
- the vertical and horizontal size and position of this rectangular area are determined during the Epoch period. It is fixed initially.
- Epoch is a unit on the playback time axis that can guarantee the synchronization of one video and one graph. If you want to change the area where graphics are to be erased and redrawn on the graphics plane, you must define the change time point on the playback time axis and assign a new Epoch after that change time point. No. In this case, synchronization of video-graphics is not guaranteed at the boundary between the two Epochs.
- FIG. 6 is a diagram showing the relationship between the subtitle display position and Epoch.
- consideration is given to changing the position of subtitles according to the design of each picture of the moving image. In other words, out of the five subtitles “Really,” “I was sorry,” “I'm sorry,” “After that,” and “Three years passed,” three of the subtitles, “Really,” “I was spoken,” and “Sorry,” At the bottom, "from that” and "three years old” are located at the top of the screen.

- Epoch It can be seen that the Start, Acquisition Point, Normal Case and ⁇ ⁇ ⁇ series of DS constitute the first stage Epoch. "Epoch Start”, “Acquisition Point”, and “Normal CaseJ” are DS types. The order of Acquisition Point and Normal Case in this figure is merely an example, and either order may be used.
- Epoch Start is a DS that has a display effect of “new display” and indicates the start of a new Epoch. Therefore, Epoch Start includes all the functional segments required for the next screen composition. The Epoch Start is placed at a location where cueing is known to occur, such as a chapter in a movie.
- “Acquisition Point” is a Display Set that provides a display effect called “display refresh” and is exactly the same as the preceding Epoch Start.
- the Acquisition Point DS is not at the start of Epoch, but includes all the functional segments required for the next screen composition. It can be realized reliably. In other words, the DS, the Acquisition Point, has the role of enabling screen composition from the middle of the Epoch.
- the Acquisition Poiht Display Set is installed at a location where you can find the beginning. Such locations include those that can be specified by a time search.
- Time search is an operation that accepts a time input of minutes and seconds from the user and searches for the beginning from the playback time point corresponding to the time input. Such a time input is made in a rough unit such as a unit of 10 minutes and a unit of 10 seconds. Therefore, a reproduction position at an interval of 10 minutes and a reproduction position at an interval of 10 seconds are positions that can be designated by time search.
- Normal CaseJ is a DS that has the display effect of“ display update ”and includes only the differences from the previous screen composition.
- the subtitle of a certain DSv has the same contents as the preceding DSu, but the screen configuration is If it is different from the DSu to be used, a PCS and a DSv with only END are provided, and this DSv is used as a DS in the normal case. This eliminates the need to provide overlapping 0DSs, which can contribute to a reduction in the capacity of the BD-R0M.
- the DS of the Normal Case is only a difference, the screen cannot be composed by the Normal Case alone.
- “Object_Definition_Segment” is a functional segment that defines a graphics object. This graphics object will be described below. Since the AVClip recorded on the BD-R0M has a sales point of high image quality equivalent to high vision, the resolution of the graphics task object is also set to a high resolution of 1920 x 1080 pixels. Have been. With a resolution of 1920 x 1080, BD-R0M can vividly reproduce subtitles for theatrical screenings, that is, handwritten and tasteful fonts.

- Pixel Code is an 8-bit value and takes a value from 1 to 255. In the run-length data, this Pixel Code allows the user to select any 256 colors from the full power 16,777,216 colors and set them as pixel colors. When displayed as subtitles, graphic graphics objects must be rendered by placing character strings on a transparent background.
- a graphics object is defined by 0DS with a data structure as shown in Fig. 7 (a).
- the 0DS has a “segment_type” that indicates that it is itself a 0DS, a “segment length” that indicates the data length of the 0DS, and a graph object corresponding to this 0DS in Epoch.

When one or more graphics objects are stored, each area in the memory space of the object buffer will be identified by this object_id. If an obj ec t—id is added to two or more Display sets, the graphics object corresponding to the preceding 0DS is stored in the object buffer.
- the size of the following graphics object When overwriting a graphics object, the size of the following graphics object must be the same size as the preceding one. Must not be too small or too large due to the preceding graphics object. It is the responsibility of the authoring staff to create the graphics objects so that they are the same size when updating. become.

- Window—def ini on—segment is a functional segment for defining a rectangular area of the graphics plane. Epoch has already mentioned that continuity of memory management occurs only when clearing and redrawing are performed within a certain rectangular area in the graphics plane. The rectangular area in this graphics plane is called “window” and is defined in this WDS.
- FIG. 8A shows the data structure of WDS. As shown in this figure, WDS indicates the “window-id” that uniquely identifies a window in the graphics plane and the horizontal position of the upper left pixel in the graphics plane.
- Horizontal video—It has a two-dimensional size called width.
- window_horizontal_position is the horizontal address of the upper left pixel in the graphics plane, and therefore takes the value of l ⁇ video_width. Take the value of video_height.
- window—width is the width of the window in the graphics plane, so it takes a value from 1 to video—width-window—horizontal—position, and window—height is the height in the graphics plane. Therefore, take the value of 1- video- weight- window-vertical-position.
- the TOS window—horizontal—position, window—vertical—position, window_width, and window—height determine where to place the window in the graphics plane and how large the window is.
- the END of Display Set Segment is an index indicating the end of the transmission of the Display Set, and is placed immediately after the last 0DS among the functional segments in the Display Set.

- object—horizontal—position, object—vertical—position is located in the range cpl of the broken line with the reference point (upper left) as the reference point. In this way, “true” is written in the window on the graphics plane. As a result, the subtitle “Sure” is combined with the moving image and displayed.
- FIG. 11A is a diagram showing an example of a PCSC description in DS2.

- FIG. 13 is a diagram showing a memory space in an object buffer for realizing the graphics update as shown in FIGS. 10 to 12. As shown in this figure, there are four storage areas A, B, C, and D whose height, width, and position are fixed, and the storage area A is shown in Fig. 11 Subtitles are stored. Each of these four storage areas A, B, C, and D is identified by an object_id corresponding to the stored graph exo object.
- the height and width of these storage areas are fixed throughout. If a new graphics object with the same object-id is obtained by decoding, its storage area is overwritten by the newly obtained graphics object. For example, if you want to display subtitles at the same position and at the same size as the subtitles shown in FIG. 10, in a subsequent Display Set, A 0DS with the same obj ec t_id may be provided. By simply adding the same obj ec t_id in this way, the graphics object existing on the object buffer is overwritten with a new graphics object, and the new graphics object is Will be displayed in the same size and in the same position as the previous graphics object.
- window clearing and window redrawing are required. If window clearing and window redrawing are to be implemented in video frame time intervals, how much transfer rate is required between the object buffer and the graphics plane?
- window clearing and window redrawing must be performed at this transfer rate Rc. Then, window clearing and window redrawing must be realized at half the transfer rate of Rc (Rc / 2).
- the size of the entire graphics plane must be at least 25% to 33%.
- Rc can be calculated as 256 Mbps (500K bytes x 2 x 29.97).
- the transfer rate is 256Mbps. As long as subtitles are displayed, synchronization with the video can be maintained regardless of the display effect.
- the window clearing and redrawing rates are only 1/2 and 1/4 of the frame rate of the video frame, the window size is doubled and 4 times even if Rc is the same. Can be doubled. This concludes the description of the size of window.
- the position and range of the window will be described. As mentioned above, the window position and range are consistent in Epoch.
- the reason for keeping the window position and range consistent in Epoch is as follows. If the window position 'range is changed, the write destination address for the graphics plane must be changed, and an over-head occurs, and such an over-head causes the object buffer to move to the graphics plane. This is because the transfer rate of the data is reduced.
- the window has a limited number of graphics objects. This number limit is provided for the purpose of reducing the overhead in transferring the decoded graphics object.
- the overhead here occurs when the address of the edge part of the graphics object is set. Then, as the number of edges increases, the number of occurrences of overhead increases.
- the transfer rate may be set in anticipation of a worst case of four overheads, so the minimum standard transfer It is easy to quantify the rate.
- Epoch is a period in which memory management is continuous on the playback time axis, and since Epoch is composed of one or more Display sets, how to assign Display Set to the playback time axis of AVC lip This Is a problem.
- the playback time axis of the AVClip refers to a time axis assumed to specify the decoding timing and playback timing of each picture data constituting the video stream multiplexed on the AVClip. In this playback time axis, the decoding timing and playback timing are expressed with a time accuracy of 90 KHz.
- the DTS and PTS added to the PCS and ODS in the Display Set indicate the timing at which synchronous control should be realized on this playback time axis.
- Performing synchronization control using the DTS and PTS added to the PCS and ODS is the assignment of Display Sets to the playback time axis.
- DTS indicates the time to start decoding of 0DS with a time accuracy of 90 KHz
- PTS indicates the decoding end time
- the decoding of 0DS is not completed instantaneously but has a long time.
- the DTS and PTS for 0DS indicate the decoding start time and decoding end time.
- the decoding start time of any ODSj belonging to DSn is indicated in DTS (DSn [0DSj]) with a time accuracy of 90 KHz, and the time obtained by adding the maximum time required for decoding to this is the decoding time of ODSj in the Display Set. It becomes the end time of the network.
- the decoding end time (90KHZ) to be indicated by the PTS is expressed by the formula:
- the OTSj PTS belonging to the calculated c DSn Then, the following expression is obtained.
- PTS (DS [0DSj]) DTS (DSn [ODSj]) + 90,000 ⁇ (SIZE (DSn [0DSj]) // Rd) And between two adjacent 0DS (0DSj, 0DSj + l) The following relationship must be satisfied.
- the decoding end time of the last ODS (ODSlast) belonging to DSn may be indicated. Since the decoding end time is indicated in the PTS of 0DS2 (0DSlast) (PTS (DSn [ODSlast])), the PTS of END is set to the value shown in the following equation.
- the DTS value of the PCS indicates the start of decoding of the first ODS (ODSl) in DSn or earlier. Because the PCS starts decoding the first ODS (ODSl) in DSn (DTS (DSn [0DSl])) and the time when the first PDS (PDSl) in DSn becomes valid (PTS (DSn [PDSl]). At the same time as or before)), it must be loaded into a buffer on the playback device. Therefore, it must be set to a value that satisfies the relationship of the following equation.
- the PTS of PCS in DSn is calculated from the following equation.
- the decodeduration is the time required for decoding and displaying all the graphics X-blocks used in the PCS update. This decoding time is not a fixed value. However, it does not fluctuate depending on the state of each playback device or the mounting of the playback device. If the object used for screen composition of this DSn.PCSn is DSn.PCSn.0BJ [j],
- the decodeduration (DSn) is the time required for window clearing (i),
- the value is affected by the decoding period of DSn.PCSn.0BJ (ii) and the time required to write DSn.PCSn.0BJ (iii). As long as Rd and Rc are determined in advance, the values will be the same regardless of the playback device mounted. Therefore, when authoring, calculate the length of these periods and PTS is calculated from the value of.
- FIG. 15 The calculation of decode_duration is performed based on the program in Figure 14.
- Figures 15 and 16 (a) and (b) are flow charts that illustrate the algorithm of this program. Hereinafter, the calculation of decode-duration will be described with reference to these figures.
- the PLANEINITIALIZATINTIME function is called, and the return value is added to decode_duration (step S 1 in FIG. 15).
- the PLANEINITIALIZATINTIME function (Fig. 16 (a)) is a function to call a function that calculates the time required for initializing the graphics plane when displaying the Display Set.
- step S1 in Fig. 15, DSn, DSn.PCS.OBJ [0], decode_durtation are set as arguments, and this function is called.
- initialize_duration is a variable that indicates the return value of the PLANEINITIALIZATINTIME function.
- Step S2 in FIG. 16 is an if statement that switches processing depending on whether the component_state in the DSS PCS is Epoch Start. If the composition_state power is SEpoch Start (Fig. 14
- step S4 The process of adding to the initial_duration_duration is repeated for all windows. If the transfer rate Rc between the object buffer graphic planes is 256,000,000 as described above, and the window belonging to the WDS The time required for clearing (seconds) is ⁇ SIZE (WDS. WIN [i]) // 256,000,000,000 J. If this is multiplied by 90,000 Hz and expressed by the time accuracy of PTS, the time required to clear all windows belonging to WDS is “90000 x ⁇
- the waiting time is added to decode_duration (step S6).
- the argument for calling this function is
- FIG. 16 (b) is a flowchart showing the processing procedure of the WAIT function.
- current—duration is
- decode dueration is set.
- object defined—ready—time is
- the current-time is a variable that sets the value obtained by adding the current-duration to the DTS of the DSS PCS. From this current—time
- step S6 for the decode—duration, the sum of the return value of this wait function and the time required to draw OBJ [0] on the window (90, 000 * (SIZE (DSn. WDS. WIN [0])) // 256, 000, 000) is set (step S 9).
- step S 10 Call the wait function with DSn, DSn.PCS.OBJ [0] and decode_duration as arguments, and add its return value to decode-duration (step S10).
- step S 1 Time required for redrawing w i ndo w to which OBJ [0] belongs
- step S11 If the window to which it belongs is different ("different" in step S11), the time required to redraw the window to which OBJ [0] belongs
- a wait function is called with DSn, DSn.PCS.0BJ [l] and decode_duration as arguments, and the return value wait—duration is added to decode_duration (step S16). Then, when necessary to redraw the window to which 0BJ [1] belongs The interval (90,000 * (SIZE (DSn. WDS. OBJ [1] ⁇ window—id) ⁇ 256, 000, 000) is calculated as decode—duration (step S 17).
- Fig. 17 (a) is a diagram assuming a case where one 0DS exists in one window.
- Figures 17 (b) and (c) are timing charts showing the temporal context of the values quoted in Figure 14. This chart has three stages. Of these stages, the “Graphics Plane Access” stage and the “0DS Decode” stage are two stages that are performed in parallel during playback. Indicates processing. The above algorithm assumes the parallel execution of these two processes.
- the graphics plane access consists of a clear period (1) and a write period (3).
- This clear period (1) is the time required to clear the entire graphics plane (90,000x (size of the graphics plane // 256, 000,000)), and the time required to clear all windows in the graphics plane. ( ⁇ (90, 000 X (size of window [i] ⁇ 256, 000, 000)))).
- the writing period (3) means a period required for drawing the entire window (90,000 ⁇ (window size ⁇ 256,000,000)).
- the decoding period (2) means the period shown from DTS to PTS of 0DS.
- the clear period (1) to the write period (3) can vary depending on the range to be cleared, the size of the 0DS to be decoded, and the size of the graphics object to be written on the graphics plane. In this figure, for the sake of simplicity, it is assumed that the starting point of the 0DS decoding period (2) is the same as the starting point of the clear period (1).
- Fig. 17 (b) shows the case where the decoding period (2) becomes longer.
- Decode_Duration is the decoding period (2) + the writing period (3).
- Fig. 17 (c) shows the case where the clear period (1) becomes longer.
- Decode_Duration consists of a clear period (1) + a write period (3).
- FIGs 18 (a) to 18 (c) assume a case where two ODSs exist in one window.
- the decoding period (2) in these figures (b) and (c) means the sum of the periods required for decoding two graphics.
- the graphics writing period (3) also refers to the sum of the periods for writing two graphics to the graphics plane.
- Decode-Duration can be calculated by considering it in the same way as in Figure 17. If the decoding period (2) for decoding two 0DSs is long, Decode—Duration is calculated as the decoding period (2) + the writing period (3) as shown in Fig. 18 (b). Will be done.
- Decode—Duration is the clear period (1) + write period (3).
- Figure 19 (a) assumes a case where there is one 0DS in each of the two windows. Even in this case, if the clear period (1) is longer than the total decode period (2) for decoding two 0DS,
- Decode_Duration is the clear period (1) + the write period (3). Problem 'is the case where the clear period (1) is shorter than the decode period (2). In this case, writing to the first window becomes possible without waiting for the decoding period (2) to elapse. Therefore, it is not the length of the clear period (1) + write period (3) and the decode period (2) + write period (3).
- the period required for the decoding of the first 0DS is referred to as a writing period (31), and the period required for the decoding of the second 0DS is referred to as a writing period (32).
- Fig. 19 (b) shows the case where the decoding period (2) is longer than the clear period (1) + the writing period (31). In this case, Decode_Duration is the decoding period (2) + the writing period (32).
- Figure 19 (c) shows the case where the clear period (1) + the write period (31) is longer than the decode period (2).
- Decode_Duration is the clear period (1) + write period (31) + write period (32).
- the size of the graphics plane is known in advance from the player model, and the size of the window, the size of the 0DS, and the number of them are also known at the authoring stage.
- PTS of the PCS is set based on such Decode-Duration calculation, synchronous display with picture data can be realized with high time accuracy.
- Such high-precision synchronous control is realized by defining a window and limiting the clearing / redrawing range to this window, so the concept of this window is introduced into the authoring environment. This is significant. '
- the DTS of WDS should be set so as to satisfy the following formula.
- the PTS of WDS in DSn indicates the dead line at which writing to the graphics plane should be started.
- Writing to the graphics plane requires only a window, so writing to the graphics plane should be started by subtracting the time required for writing the WDS from the time indicated in the PTS of the PCS. The time is fixed. If the total size of the WDS is DSSIZECWDS.WINti]), the time required for clearing and redrawing is ⁇ ⁇ SIZE (TOS.WIN [i]) ⁇ 256,000,000. Then, if this is expressed with the time accuracy of 90. OOOKHz, “90000 X ⁇
- the PTS of the WDS may be calculated from the following equation.
- PTS (DSn [WDS]) PTS (DSn [PCS]) -90000 x ⁇

- the above is the internal configuration of the playback device.
- the graphics decoder 12 can be implemented by creating a program for performing the processing procedure of FIG. 33 and causing the CPU to execute the program.
- the processing procedure of the control unit 20 will be described with reference to FIG.
- FIG. 33 is a flowchart showing a processing procedure for loading a functional segment.
- SegmentK is a variable that means each of the read Segments (PCS, WDS, PDS, 0DS) at the time of playback of the AVC lip, and the ignore flag indicates whether this SegmentK should be ignored. This is a flag to switch whether to load.
- This flow chart is Has a loop structure in which the processing of steps S 21 to S 24 and steps S 27 to S 31 is repeated for all Segment Ks after initializing the processing to steps S 21 to S 24 (steps S 25 and S 2 6).
- Step S21 is a determination as to whether or not SegmentK is a PCS. If SegmentK is a PCS, the determination in steps S27 and S28 is performed.
- Step S22 is to determine whether or not the ignore flag is 1. If the ignore flag is 0, the process proceeds to step S23, and if it is 1, the process proceeds to step S24. If the ignore flag is 1 (No in step S22), the segment K is loaded into the coded data buffer 13 in step S23.
- Step S24 If the ignore flag is set to 0 (No in Step S22), SegmentK is ignored in Step S24. As a result, all the function segments belonging to the DS are ignored in step S22, resulting in No (step S24).
- Steps S27 to S31, S34, and S35 are processes for setting the ignore flag.
- Step 27 is a judgment as to whether or not the composition point is the Acquisition Point in the PCS. If SegmentK is the Acquisition Point, the process proceeds to step S28. If SegmentK is Epoch Start or Normal Case, the process proceeds to step S31.
- step S28 if the preceding DS is any one of the graphics decoders 12, the software (Coded Data Buffer 13, Stream Graphics Processor 14, Object Buffer 15, Composition Buffer 16) This is a determination as to whether or not it exists in step S.27, and is executed if step S.27 is Yes.
- the case where no DS exists in the graphics decoder 12 refers to the case where the cue has been performed. In this case, the display must be started from the DS, which is the acquisition point, so that the process proceeds to step S30 (No in step S28).
- step S30 the ignore flag is set to 0, and the flow advances to step S22.
- step S29 the ignore flag is set to 1, and the flow shifts to step S22.
- step S31 it is determined whether or not the composition is one state SNormal Case in the PCS. If it is a normal case, the process proceeds to step S34. If SegmentK is Epoch Start, set the ignore flag to 0 in step S30. Step S34 is the same as step S28, and determines whether or not the preceding DS exists in the graphics decoder 12. If it exists, the ignore flag is set to 0 (step S30). If not, the ignore flag is set to 1 (step S35) because a sufficient functional segment for composing the interactive screen cannot be obtained. With such a flag setting, when the preceding DS does not exist in the graphics decoder 12, the functional segments constituting the Normal Case are ignored.
- the first DS1 is the composition-state power SEpoch one Start
- DS10 is the Acquisition Point
- DS20 is the Normal Case.
- the cue from the picture data ptlO is performed as indicated by the arrow ami.
- the DS10 closest to the cue position is the subject of the flowchart in Figure 33.
- the composition_state is determined to be Acquisition Point, but since the preceding DS does not exist in Coded Data Buffer 13, the ignore flag is set to 0, and this DS10 is set as shown by the arrow mdl in Fig. 35. Is loaded into the Coded Data Buffer 13 of the playback device.
- DS20 is a normal case display set, and the preceding DS20 does not exist in Coded Data Buffer 13 so this display set will be ignored (arrow in Fig. 35).
- the ignore flag is set to 1 (step S29), so the function segments that make up this are not loaded into Coded Data Buffer 13 and are ignored ( Figure 3). Arrow 7 rd2, step S24).
- the composition state of the PCS is Normal Case, so it is loaded into Coded Data Buffer 13 (arrow rd3 in Fig. 37).
- FIGS. 38 to 40 are flowcharts showing the processing procedure of the Graphical Controller 17.
- Steps S41 to S44 are the main routine of the present flowchart, and wait for the establishment of any of the events specified in steps S41 to S44.
- Step S41 is a judgment as to whether or not the current reproduction point is at the DTS time of the PCS. If not, the processing of steps S45 to S53 is performed.
- Step S45 is a judgment as to whether or not the composition-state power of the PCS is Epoch-Start. If it is Epoch Start, all the graphics planes 8 are cleared in Step S46. Otherwise, in step S47, the window indicated by window_horizontal—position, window—vertival—position, window—width, and window—height of the WDS is cleared.
- Step S48 is a step executed after the clearing in step S46 or step S47, and the PTS time of any ODSx has already passed. It is a judgment of whether or not it is performed. In other words, since clearing the entire graphics plane 8 takes a long time in the clearing time, decoding of a certain ODS (ODSx) may have already been completed. Step S48 verifies that possibility. If not, return to Mainle-Chin. If the decoding time of any of the 0DS has passed, steps S49 to S51 are executed. Step S49 is a judgment as to whether or not the object_cropped-flag indicates 0. If the flag indicates 0, the graphics object is hidden (step S50).
- the graphics object cropped according to cropping_height is displayed in the graphics plane 8 window.
- step S51 Write at the position indicated by object—horizontal—position, object—vertival—position (step S51). With the above processing, one or more graphic objects are drawn in the window.
- Step S52 is to determine whether or not the PTS time of another ODSy has elapsed. If the decoding of another 0DS has already been completed while writing ODSx on the graphics plane 8, this ODSy is changed to ODSx (step S53), and the process proceeds to step S49. Thus, the processing of steps S49 to S51 is repeatedly performed for another 0DS.
- Step S42, Step S54 to Step S59 will be described with reference to FIG.
- Step S42 is to determine whether or not the current playback point is the PTS of the TOS. If the current playback point is the PTS of the WDS, it is determined whether or not there is one window ⁇ in step S54. If there are two, it returns to the main routine. If there is only one window, the loop processing from step S55 to step S59 is performed. In this loop processing, steps S57 to S59 are executed for each of the two graphics objects displayed in the window. Step S57 is a determination as to whether or not the object one croppecLflag indicates 0, and if so, the graphics object is hidden (step S58).
