- FIG. 61 is a flowchart showing the operation of the ⁇ TSTC transection chest unit 32018 shown in FIG. 39 at the time of seamless playback.
- step # 311220 the STC offset is calculated, and the flow advances to step # 311221.
- the STC offset calculation method is used to finish the display of the last video frame in V ⁇ to be reproduced first.
- Step # 311221 the calculated STC offset value STCo f is set in the STC updating unit 32016 to update the STC, and then the process proceeds to Step # 3 11222. That is, in STCMfi3 ⁇ 432016, the output STCc of the STC counter 32014 and the output STCo f from the STC offset calculator 32012 are calculated as ⁇ :( STCc ⁇ S Cbf) and output as STCr.
- step # 3112222 1 (FIG. 40), that is, in the case of the SCR force from the stream VOB # 1 to VOB # 2; STCr is output at the moment of switching, and the process proceeds to step # 311223.

That is, when the STCr coincides with the APTS, the ⁇ of the audio corresponding to the APTS is performed.
- step # 311224 STC r is selected in 3 (FIG. 40), that is, in the orchid where VDTS force S switches from stream VOB # 1 to VOB # 2, and the process proceeds to step # 311225.
- the video decoder STCr is given to the STC value to be referred to, and the timing of the VOB # 2 video code is determined by the VDTS in the video bucket and the STC r. That is, when the STCr matches the VDTS, the video data corresponding to the VDTS is decoded.
- step # 311225 the sword T4, that is, the VPTS force is switched from stream VOB # 1 to VOB # 2, the STCr is output 51 ⁇ , and the process proceeds to step # 311226. Thereafter, the STC value referred to by the sub-picture decoder is given the output power of STCr, and the sub-picture display timing of VOB # 2 is determined by the PTS in the sub-picture bucket and the STCr.
- the STCr matches the PTS of the sub-picture
- the sub-picture data corresponding to the PTS is reproduced. Note that since the subpicture is decoded from display to display, the video ⁇ is changed to the subpicture decoder at the same timing as when the TV PTS switches from VOB # 1 to VOB # 2. Will also switch the STC value referenced by.
- step # 311226 the STCr is set in the STC setting section 32010, and the STC counter 32014 is operated using as an observation value, and the flow advances to step # 311227.

- the output STCc of the STC counter 32014 is set to ⁇ 1 ⁇ as the SC value to be used for video: ⁇ coder, sub-picture decoder, audio; ⁇ coder, system decoder.
- the processing from step 311226 to step 311227 may be performed before the timing at which SC switches from VOB # 2 to the next VOB, that is, time T1 when switching to the next VOB. .
- V0B_V_3PIM indicates the opening of the VOB battle, and indicates the end of the display of the VOB—V—EFM or the VOB. The same Of line is performed in all NV packs in the same VOB. Therefore, V0B_V_SFI (In truth, V0ELV_EPTM's transformation is VOB power; it * has changed.
- V0B_V_EPIM3 ⁇ 4 is a VOB-V-SPI transformation, which allows the user to know the VOB transformation.
- VO B change T1 can be obtained by adding 1 pack ⁇ to the SCR value in the pack of 3 ⁇ 4ir.
- One pack ⁇ is given as a fixed value.
- T3, T2 can be calculated from VTSTS in the NV pack or from APTS, VDTS, VPTS extracted immediately before VOB-VJPM conversion.

- T3 it can be humiliated by extracting the video packet power VDTS including the VDTS immediately before the VOB is switched.
- VDTS 3 ⁇ 4H " ⁇ .
- VOB-V_EPIM and ⁇ ffi so VOB-V-EFIM can be ⁇ ffl.
- Synchronization W3 ⁇ 4P 2900 is based on ST C3 ⁇ 432030, PTS / DTS extractor 32031, same as ⁇ WJ3 ⁇ 43 ⁇ 4
- ST ⁇ unit 32030 is a block that performs the system clock in each decoder, and synchronizes with video coder synchronization 2033, sub-picture decoder synchronization control 32034, audio;
- the STC ⁇ 32030 is composed of a counter that runs on the system clock. Will be up. This age, APTS or VPTS, may be defined as the straight line of the STC counter.
- Both audio output and video output are synchronized with the output clock. Therefore, there is a possibility that the STC, the audio output clock, and the video output clock will make the synchronization possible. If this ⁇ becomes large, there is a possibility that each decoder buffer will threaten (overflow or underflow). Therefore, for example, by periodically setting the APTS synchronized with the audio output clock in the STC, the error between the APTS and the STC does not change, so that the audio can be continuously cut. This to the video In this regard, synchronization is controlled by skipping or freezing the video output. Such an audio sync »Audio: Star sync.
- the synchronization mode ON indicates that the synchronization chest is controlled by the STC (audio / star is a video / video), and the synchronization mode is OFF, as described above.
- the STC synchronized cold ⁇ ⁇ ⁇ 3 ⁇ 4 ⁇ .
- each of the video and audio decoders refers to the time stamp in the stream.
- 3 ⁇ 4 "f the video and audio data are based only on the internal clock. In this case, video and audio are not synchronized with each other.
- the PTS / DTS extraction section 32031 extracts PTS and DTS from the synchronous chest suppression data St81 and provides the PTS and DTS to each decoder synchronization channel.
- the “1 ⁇ 1 Ref 32032” performs a synchronize 1 ref for each deco period system to determine whether to perform synchronization or not (synchronous mode ON, synchronous mode OFF). This 32032 will be described in detail later with reference to FIG.

In other words, when the STC and the DTS meet, a bid is issued. If the sync mode from the sync »I» J Sub-32032 is OFF, the video decoding is started during this period (the word St 89 is always output. In other words, the video decoder does not depend on the external chest control. Decode according to the internal state.
- the sub-picture decoder synchronization system J3 ⁇ 4l3 ⁇ 432034 uses the synchronization »j ⁇ !

That is, STC and PTS power; Open ⁇ (the symbol St 91 ⁇ T. Synchronized ⁇ ⁇
- the sub-picture decoding start signal St 91 is always output during this period. In other words, decoding is performed by cold due to the internal state regardless of the chest from the sub picture decoder section.
- ⁇ Coder Sync 32035 is sync ⁇ ! If the synchronous mode is ON from 32032, the STC unit 32030 will open the STC and the audio code obtained from the PTS / DTS extraction unit 32031. ⁇ 1 From #PTS, enter the code number St 93. In other words, when the STC and the PTS are combined, the code is opened; Synchronization If the synchronization mode from $ lj3 ⁇ 4MM »320 32 is OFF, during this period audio, the code start signal St 93 is always output. In other words, decoding is performed by the control based on the internal state, regardless of the control from the audio: ⁇ coder.
- ⁇ 32036 is STC «3 ⁇ 432030 power and three others. Is output as 5179. St 79 is packed into the stream leg from the stream buffer to the system decoder. That is, if the STC value is equal to the knocking SCR value by Tt1, the packed data is decoded from the stream buffer by the system decoder.
