Description

1276085 1 33 59pifl IX. Invention Description: The invention declares that the application is the priority of the South Korean patent application case 5 Tiger 2003· 19684 on March 28, 2003. The application is the South Korean patent of November 19, 2003. The priority of the application No. 2003-82336, and the priority of the present application is hereby incorporated by reference. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reproducing apparatus and method, and more particularly to a reproducing apparatus for reproducing still image data of a browsable slide show such as a slideshow that independently adds sub sound data. And methods, as well as its recording media. [Prior Art] Since the size of the moving image data is very large, the image data must be compressed by the space-time compression method to facilitate transmission. In general, for the recording of the media on the storage media, the image data is made by ISO (international organization standardization, international standard organization) and ffiC (international electrotechnical commission, International Electrotechnical Commission)][V[PEG(Motion Picture) Experts Group, the group of experts, to compress and encode, in which the sound data is used to display the digital data or use linear pulse code modulation (PCM) to convert into digital data. The time information necessary for synchronizing the encoded image data and the sound data to each other is combined with the system multiplex data. In this case, the MPEG2 standard is often used when encoding data. The multiplex of the system can be carried out using packets. For example, as shown in Fig. 1, 1276085 1 3359pifl When the image data and the sound data are multi-JL, the image data and the sound data are divided into bit stream packets of a predetermined length, such as an additional information system such as a header. It is included in the bit stream packet, and the image packet and the sound packet are mixed and transmitted using time sharing technology. Thus, the beginning of the packet, i.e., the header, includes information indicating that the packet is an image packet or a voice packet. However, according to the MPEG standard, a time-depleted time called a time stamp is used in synchronization between an image packet and a sound packet. The essay is a time management tag located in the access unit of the decoding process required for data reproduction. That is, the time stamp is information specifying when it is necessary to decode and reproduce sound or image data in the access unit. There are two types of time stamps: Presentation time stamp (pTS) and Decoding time stamp (DTS). Pts depends on the MPEG coding method used to select the information of the day (10), which is the secret time clock (STc, the teacher such as e in the view of the G secret reference decoding 11 caps produced with the same ttt ^ TS is poor The time management information of the material decoding. The 1^0 specification needs to be 'the order of the image bit stream after the encoding is unique. The sequence of the bit stream after the encoding of the image and the p-frame image is in B. Before, decode and reproduce the sequence of the illusion (four) 彳, frame image. If the second _ tongue is included in the package data. If the same (four), 1276085 1 33 59 pifl only include the PTS in the package data. Figures 2 to 6 depict the conventional MPEG encoding and the solution of the stone horse 200. i3 = the traditional hierarchical encoding device used in MPEG encoding, the multi-Career 2 ® 'one image encoder. 21 〇 receiving and encoding digital image 舅〆 and one The audio encoder 220 receives and encodes the digital sound data. The first packetizer (paCketiZer) 230 divides the encoded image data output by the image encoder 21q into a predetermined unit to be packetized, and generates a packetized elementary stream. s Tream, PES). The first-packet state 240 reports the encoded sound material outputted by the sound encoder 22〇 into a predetermined unit to be packetized and generates PEs. The encoding time information, such as PTS and DTS, which can be incorporated into the PES. This encoding time information is used to synchronize the PES to other data. In particular, DTS indicates when the image is decoded, and pTS indicates when the image will be output. In general, only PTS Included in the sound data. In this case, 'DTS is considered to be the same as pTS. After adding pTS and DTS, the sound data or video data is encapsulated in the data content (payk) ad) data format 2 / one program stream multiplex The device 250 multiplexes the first packetizer 23 into a scene stream, such as a PES multiplex, into a program stream (pS). A transport stream multiplex 260 multiplies the sound enveloped by the second packetizer 240 into a transport stream (TS). In multiplex, each PES is divided into established units, and the identification number is assigned to the predetermined units, and then multiplexed. The PS system is used for information storage media, and is multiplexed in the ps packet ΐ 2760^9 bit. In the DVD image standard, a representative application of a dynamic image storage medium uses a 2048-bit ps packet unit. The TS system is used in, for example, digital broadcasting applications where data loss is unavoidable. The TS system is multiplexed into a TS packet unit. The length of the TS packet unit is fixed to 188 bytes. Recently, the application of ts has been increased when digital broadcast data is to be recorded on a storage medium. In this specification, 18 is used in multiplex, but PS can also be used. As mentioned above, the TS is packetized data, such as video or audio data, which is divided into established units so that the data can be transmitted via satellite, cable or regional network (LAN). Here, when an MPEG-2 transport stream according to the IS〇/I encoding 138(10) standard is used, the length of the predetermined unit is 188 bytes; when the asynchronous transmission mode (ATM, _t_mode) is used The length of the established unit is 53 bytes. In digital broadcasting, packet data is transmitted during variable periods. The transmitted packet data is sent to the buffering device of the receiving device with the decoder, decoded by the decoder, and broadcasted, so that the user can watch the wife: bit broadcast. The packet data can be temporarily stored on the recording medium and reproduced at the desired time. In this case, the variable period of transmission of the packet data is important for the packet data to be input to the decoder of the reproduction device. This is the value of the transmission side to adjust the packet data to the receiving side to adjust _ 包 夕 period, consider the buffering device with the solution of the receiving device: If the variable reading force is not spit, then "set the buffer memory ;^ (read flow) or under-order (10) derflow). Because *, the relevant arrival time: the arrival time of each packet data is inserted in all the envelope underwear = 1276085 i3359pifj and the packet information is based on arrival time related information As described above, when the reproduction is performed on the recording medium from the exclusive TS format, the appropriate recording device receives the special packet from the transmission side and records it on the recording medium. ==count of the specific period used by the transmission side to transmit the packet data to 90 kHz 4 27 MHz including the count value inserted into the packet data, the counter is obtained - and obtained when the counter is present ATS. Record the data into the f-report for the reproduction, and transmit the packet data to the buffer of the decoder. 2. The package: the T count value of the packet data. This counter is called; ATC ' _al time cl〇ck The counter is called counting, resulting in The count value is added to the rim ^^ The package of the shell material is output according to the ATS of the data reproduction. "Hai Shimen ^ map package is used to specify the data structure of the packet data of the ATS that arrives at the receiving side of the packet data. , 1 and D. For regeneration data, the packet data is output and reproduced according to ats ^ 1276085 1 3 3 5 9p if 1 , that is, the packet data A is output at the output time loo; the packet data B is in rotation Output at time 110; the packet D decoding is output at the turn-off time of 13 ;; and the packet data D is output at the output time of 15 。. Figure 4 shows the data of the package data 400 included on a recording medium. In the present invention, for convenience of explanation, the figure 4 shows that the package data 400 includes information such as ATS41〇, decoding time stamp (DTS) 420, and presentation time stamp (presentati〇n time stamp). , PTS) 430 'and sound/video (AV) data. Fig. 5 shows a portion of the reproducing apparatus 500 that can reproduce the packet data including the ATS as shown in Fig. 4. The reproducing apparatus 鄕& Drive unit 510, a buffer The memory 520, a source decapsulator 53A, is an ATC counter 540. The disc drive unit 510 reads the packet data including the ATS, and transmits the packet data to the buffer memory 52(). The recorder 520 receives the packet data including the ATS, and transmits the packet to the source decapsular 530. ', when the data stream stored in the recording medium is transmitted to the decoder at the first transmission side of the packet data (The ATC counter 540 is not shown. The ATC counter 54 operates in response to the 27 MHz system clock, resetting the milk value (the milk value is in the special TS format - the packet is input to the source decapsulation device, the field is the initial value, to serialize Wei The weight of the input packet is ^^) ATS is equal to the count value generated by the ATC counting crying 54 〇胼 丄 丄 入 入 入 540 540 540 540 540 540 540 540 540 移除 移除 移除 移除 移除 移除 移除 移除 移除 移除 移除 移除 移除 移除 移除 移除 移除 移除 移除Send to the decoder. 4 l276 〇 85 1 33 59 pifl That is, the ATC counter 540 sets the ATS value of the packet sent to the source decapsulation packet 530 and starts counting. Then, the source depacketizer 530 Check the ATS value of the next packet data, remove the ATS value from the packet data whose ATS value is equal to the count value generated by the ATC counter 540, and transmit the packet data to the decoder. For example, the packet data in Figure 3 Because the ATS value of the first packet data is 1 〇〇 'the initial value of the ATC counter 540 is set to 1 〇〇, and the ATC counter 540 continues to count. The ATS is removed from the first packet data, and the first A packet of data is transmitted to the decoder. Then, because of the second The ATS value of the packet data is 110. When the count value of the ATC counter 540 is 110, the source depacketizer 530 removes the ATS from the second packet data and transmits the second packet data to the decoder. The process also applies other packet data similarly. Figure 6 is a block diagram of a conventional standard decoder 6 (8) for data synchronization based on encoding time information such as PTS and DTS. Referring to Figure 6, the decoder 600 includes a demodulation A demultiplexer 61 〇, an image decoder 620, a system time clock (STC) counter 63 〇, a sound decoder 640, and an image processor 65 〇. The demodulation multiplexer 610 is multi-directional The image of the package, the sound packet data and the sub-image package data are demodulated, and the image packet and the sound packet data after demodulation are sent to the image decoding crying 620 and the sound decoding. 640. The sub-image after being demodulated and multiplexed may be a sub-picture; the picture data is played over the image packet data. In Figure 6, the decoder for decoding the sub-picture data is not displayed. 1276085 1 33 59p Ifl wood seal ^TC counter (4) operates at 9GKHZ or 27MHz, and controls the buffer memory that is enclosed in the decoder (the packet value is not equal to the program clock reference of the packet (pr〇g=reference, PCR) The buffer memory temporarily stores the packet from the demodulation multiplexed but not yet rounded to the image decoder (4), and the program clock reference, which is used to adjust the j time value of the STC counter to The image and sound numerator 2 = set value information. The solution is described in Figure 6 to describe the process of decoding including DTS and PTS. First, the demodulation multiplexer _ demodulates the input packet into a multiplex: the original image packet data and the sound packet data, and sends the image squeezing packet data to the image decoder 62 () and the sound decoder respectively. 4, the counter (4) is set according to the information contained in the packet data (not shown). The image packet data has been set to «62〇^1 ff, which has only m value, and the sound is set to the sound decoder _, which is decoded by the decoder 640 and output. The material ί2 is output from the image processing S (10) to the image processing S (10) when the PTS time set by the decoded image packet outputted by the image decoder 620 is rounded up to the image processing 5 650 ' As described above, the synchronization of the sound and the image packet data can be utilized by utilizing the 127 touch. If, SJC 5: number, the count value generated by '630, the control time and the day-to-day sound and the decoding and output of the image packet data are completed 1 'Response to the thai STC statement hexagram 63 〇 The clock, the sound is decoded like packet data and synchronized with each other. , ~ ... - In general, there are two forms of application for still images. The first is the slide 颂 2, the second still image wheel is for a given time. That is, when the user reproduces the STC value with a new value by using the 2 playback before the previous image is played (the off-play (4) or skipping the current reproduction and reproducing the image-under-image playback), the image can be updated. Continuous reproduction again. If the image includes sound data, the sound data is synchronously reproduced in the updated shirt image. Therefore, the reproduction of the sound data is discontinuous, and the sound > material, the portion of the sound data of the still image is reproduced again. The first type of slideshow can be displayed in a slideshow. In the viewable slideshow, the sound is continuous even in the river-sheet play or the next-player play. For example, 'similar to _ including (four) The way to regenerate the other side, in the reproduction of the #Browse slide show, even if the previous or next image of the image, Α ^ 目 needs to continuously reproduce the background sound ί 4 naturally reproduce the still image Still, a picture will be described in Figure 7 to describe the problem before the cut-off slide show or "F-sheet playback. Still images, such as the slide-style slide show, the main information lying down The main capital The material includes image data, sound data such as; 5 brothers can view the image in the application of the slide: the static shadow material is not = material. The county audio data represents independent of the main 2 and _ shape money sound data, and In the still image #, the sub-sound data is regenerated to generate background music. τ is the fifth picture, each of the still image and the sub-sound data is synchronized by pts (that is, the encoding time is input). When the data continues to be reproduced, the decoding is performed. The (not: out) STC count value is increased and the normal thief is based on the increased STC count value. However, when the maker wants to perform the pre-sheet playback or the next-sheet playback, the STC count value is based on the previous one. Play or play down, play the target position (such as 3000 and 20000) and adjust. If the STC tip value is updated, the STC count value is reset to i_G to restore the original still image and the original sub sound, thus causing the sub sound data ( That is, the background music is interrupted. For example, the conventional reproducing device uses the STC counter to control the image decoding state and the sound decoder. Therefore, when the conventional reproducing device is used to reproduce a still image (such as browsable) When the slide show is displayed, it is difficult to avoid interruption of the reproduction of the background music during the previous playback or the reset of the STC value during the next playback. In this case, the viewable slideshow cannot be smoothly reproduced. It is possible to cause a harsh mouth sound.
