Description

  The present invention is effective when applied to a recording / reproducing apparatus capable of handling a medium such as a hard disk and a DVD (digital versatile disk) capable of recording / reproducing information simultaneously or separately. ) Chapter recording guide / reproduction apparatus with a chapter creation guide function that allows a user to easily set a guide display.

  As is well known, in recent years, a moving image-compatible optical disk reproducing apparatus for reproducing an optical disk on which data such as video and audio is recorded has been developed. This apparatus is generally used for the purpose of enjoying movie software or enjoying karaoke, such as an LD or a video CD playback apparatus.

  Among them, a DVD standard that uses an internationally standardized MPEG2 (Moving Picture Image Coding Experts Group) system and an AC-3 audio compression system has been proposed.

  According to the MPEG2 system layer, this standard supports the MPEG2 system as a moving picture compression system, and supports the AC3 audio compression system and the MPEG audio compression system as audio compression systems. In addition, sub-picture data obtained by run-length compression of bitmap data can be handled for subtitles such as movies and karaoke. Furthermore, in this standard, special playback control data (navigation pack) such as fast-forward / reverse feed is added in relation to the playback device.

  Furthermore, this standard supports IS0 (International Organization for Standardization) 9660 and micro UDF (Universal Disc Format) standards so that the data on the disc can be read by a computer.

  In addition, as a standard of the media itself, following the DVD-ROM standard which is a DVD-video medium, a DVD-RAM standard [recording capacity of about 4.7 GB (Giga Bytes)] has been completed, and a DVD-RAM drive is also available. It has begun to spread as a computer peripheral device.

  Furthermore, a DVD video standard that realizes a system capable of recording and reproducing information in real time using DVD-RAM, that is, a standard of RTR (Real Time Recording) -DVD is being completed. Is also scheduled to end.

  This standard is considered based on the DVD-video standard that has already been released. Furthermore, a file system corresponding to the RTR-DVD is also currently standardized.

  On the other hand, a method of recording and reproducing broadcast signals using a hard disk device (HDD) built in the recording and reproducing device is also considered. The hard disk device can record data of 100 GB or more.

  In the hard disk device and the DVD system described above, it is sufficiently possible to provide a reserved recording function as in the conventional VTR. Further, since these media have a large storage capacity, it is possible to record a large number of programs (titles) or programs (titles) for a long time.

  When a long program is recorded, the user often wants to set chapters. However, there is no conventional method for easily creating chapters.

  SUMMARY OF THE INVENTION The present invention has been made in consideration of the above circumstances, and an object thereof is to provide a recording / reproducing apparatus with a chapter creation guide function that can be easily created while checking chapters on a screen.

Means for setting a button area for instructing chapter boundaries during playback of, between the video playback area and the thumbnail display area of the screen of the display means, sets a rod-like display areas corresponding to the length of the program And a means for adding a mark corresponding to the number of chapters existing in the program to the bar-shaped display area and displaying it on the screen of the display means whether the title including the chapter is an original program. Means for displaying an identification area for identifying whether it is based on the playlist, and the previous chapter so that it can be combined with the desired chapter when the cursor is positioned on the corresponding thumbnail to combine the divided chapters. And means for obtaining an indication of “combination / combination with subsequent chapter”.

  According to the configuration as described above, it is possible to arrange the areas displayed on one screen in an easy-to-see manner.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an embodiment of a recording / reproducing apparatus to which the present invention is applied. Although this embodiment shows a recording / reproducing apparatus capable of handling both a DVD-RAM and a hard disk as a recording medium, the present invention is also applied to an apparatus that handles only one of the recording media. Is possible.

  1 is roughly divided, the left side shows the main blocks of the recording unit, and the right side shows the main blocks of the reproducing unit.

  The playback processing in the recording / playback apparatus shown in FIG. 1 is performed according to program chain information (PGCI) indicating the playback order of programs. In this PGCI, a plurality of programs (PG) can be specified. Information (CI) is defined. Then, the cell entry point (C_EPI) is designated by the CI, and the VOB to be reproduced is specified. In addition, a special PGC for reproducing in the recording order is referred to as an original PGC, and information on the original PGC is recorded as ORG_PGCI. Furthermore, the attribute information (resolution information, aspect information, audio attribute information, etc.) of the video data at this time is recorded in stream information (STI) in VMGI. A pack is a minimum unit for performing data transfer processing. Further, the minimum unit for performing logical processing is a cell, and logical processing is performed in this unit. Therefore, when recording is performed, the recording signal is converted into a format that matches the above format.

  The recording / reproducing apparatus includes a hard disk drive device 2001, a disk drive 35 that rotates and drives an optical disk 1001 that is an information storage medium capable of constructing a video file, and reads / writes information from / to the optical disk 1001 and a recording side. The encoder 50, the decoder 60 constituting the reproduction side, and the microcomputer block 30 for controlling the operation of the apparatus main body are main components.

  The encoder unit 50 includes an ADC (analog / digital converter) 52, a V (video) encoder, an A (audio) encoder, an encoder group 53 including an SP (sub-picture) encoder, and an output of each encoder in a predetermined format. The formatter 56 and the buffer memory 57 are provided.

  The ADC 52 receives an external analog video signal + external analog audio signal from the AV input unit 42 or an analog video signal + analog audio signal from the TV (television) tuner 44.

  The ADC 52 digitizes the input analog video signal with, for example, a sampling frequency of 13.5 MHz and a quantization bit number of 8 bits. That is, the luminance component Y, the color difference component Cr (or YR), and the color difference component Cb (or YB) are each quantized with 8 bits.

  Similarly, the ADC 52 digitizes the input analog audio signal with, for example, a sampling frequency of 48 kHz and a quantization bit number of 16 bits.

  When a digital video signal or digital audio signal is input to the ADC 52, the ADC 52 causes the digital video signal or digital audio signal to pass through. Further, jitter reduction processing, sampling rate change processing, and the like may be performed on these digital video signals and digital audio signals without changing the contents.

  The digital video signal output from the ADC 52 is sent to the formatter 56 via the V encoder. The digital audio signal output from the ADC 52 is sent to the formatter 56 via the A encoder.

  The V encoder has a function of converting an input digital video signal into a digital signal compressed at a variable bit rate based on the MPEG2 or MPEG1 standard. The A encoder has a function of converting an input digital audio signal into a digital signal compressed at a fixed bit rate or a linear PCM digital signal based on the MPEG or AC-3 standard.

  When sub-video information is input from the AV input unit 42 (for example, a signal from a DVD video player with an independent output terminal of a sub-video signal), or a DVD video signal having such a data structure is broadcast and is transmitted to the TV tuner 44. Is received, the sub video signal (sub video pack) in the DVD video signal is input to the SP encoder. The sub video signal input to the SP encoder is arranged in a predetermined signal form and sent to the formatter 56.

  The formatter 56 conforms to a predetermined DVD format (file structure) by performing predetermined signal processing on the input video signal, audio signal, sub-picture signal, etc. while using the buffer memory 57 as a work area. The recorded data is output to the data processor 36.

  Here, the apparatus can supply the information encoded by the encoder unit 50 and the created management information to the hard disk device 2001 via the data processor 36 and record the information on the hard disk. Information recorded on the hard disk can also be recorded on the optical disk 1001 via the data processor 36 and the disk drive 35. Furthermore, the information encoded by the encoder unit 50 and the created management information can be recorded on the optical disc 1001 via the data processor 36 and the disc drive 35.

  In addition, when the information recorded on the hard disk of the hard disk device 2001 is the same as the data format of the optical disk 1001, the recording / reproducing apparatus can record the information on the hard disk on the optical disk without being encoded.

  If the information recorded on the hard disk of the hard disk device 2001 is different from the data format of the optical disk 1001, the information read from the hard disk is encoded by the encoder unit 50. The encoded information can be recorded on the optical disc 1001.

  Here, a standard encoding process for creating recording data on the optical disc 1001 will be briefly described. That is, when encoding processing is started in the encoder unit 50, parameters necessary for encoding video (main video) data and audio data are set.

  Next, the main video data is pre-encoded using the set parameters to calculate the optimum code amount distribution for the set average transfer rate (recording rate). Based on the code amount distribution obtained by the pre-encoding process, the encoding process of the main video data is executed. At this time, the audio data encoding process is also executed. Similarly, parameters necessary for encoding the sub-picture data are set, and the encoded sub-picture data is created.

  The encoded main video data, audio data, and sub-video data are combined and converted into a video object set VOBS structure.

  That is, a cell is set as the minimum unit of main video data (video data), and cell information is created. Next, the configuration of the cells that make up the program chain PGC, and the attributes of the main video, sub-video, and audio are set (part of these attribute information is used by the information obtained when each data is encoded) Here, a VMG file including various information is created.

  The encoded main video data, audio data, and sub-video data are subdivided into packs of a certain size (2048 bytes). In the pack, time stamps such as PTS (Presentation Time Stamp) indicating playback time and DTS (Decoding Time Stamp) indicating decoding time are described as appropriate. For the sub-picture PTS, a time arbitrarily delayed from the PTS of the main picture data or audio data in the same reproduction time zone can be described.

  Each cell is arranged while an RDI pack (corresponding to a navigation pack) is arranged at the head of each video object unit VOBU so that the data can be reproduced in the time code order. Thereby, a video object VOB including a plurality of cells is configured. A video object set VOBS obtained by collecting one or more video objects VOB is recorded as a program in a movie video file.

  When the DVD playback signal is digitally copied from the DVD video player, the contents of the cell, the program chain, the management table, the time stamp, and the like are determined from the beginning, and it is not necessary to create them again.

  The parts for reading and writing (recording and / or reproducing) information with respect to the optical disc 1001 include a disc drive 35 having an optical system and a drive system, a data processor 36, a temporary storage unit 37, and an STC (system time). Counter or system time clock) 38.

  The temporary storage unit 37 buffers a certain amount of data (data output from the encoder unit 50) written to the optical disc 1001 via the data processor 36 and the disk drive 35, and stores the disk drive 35 and the data processor 36. Is used to buffer a certain amount of data reproduced from the optical disc 1001 (data input to the decoder unit 60) via the. The disk drive 35 includes a rotation control system, a laser drive system, an optical system, and the like for the optical disk 1001.

  For example, when the temporary storage unit 37 is composed of a 4 MB (Mega Bytes) semiconductor memory (DRAM), buffering of recording or reproduction data for about 8 seconds at an average recording rate of 4 Mbps (bit per second) Is possible. Further, when the temporary storage unit 37 is composed of a 16 MB EEPROM (Electrically Erasable and Programmable) ROM (flash memory), recording or reproduction data buffering of about 30 seconds at an average recording rate of 4 Mbps is possible. Is possible.

  Further, when the temporary storage unit 37 is composed of a 100 MB ultra-compact HDD (hard disk drive), it is possible to buffer recording or reproduction data for 3 minutes or more at an average recording rate of 4 Mbps.

  The temporary storage unit 37 can also be used to temporarily store recording information for a short time until the optical disk 1001 is replaced with a new disk when the optical disk 1001 is used up during recording.

  However, since this recording / reproducing apparatus is provided with a hard disk device 2001 having a large capacity, this apparatus can be utilized.

  The temporary storage unit 37 can also be used to temporarily store data read out from the normal drive within a certain time when a high-speed drive (double speed or higher) is adopted as the disk drive 35. . If the read data at the time of reproduction is buffered in the temporary storage unit 37, the reproduction data buffered in the temporary storage unit 37 is switched and used even when an optical head (not shown) causes a read error due to vibration shock or the like. Thus, it is possible to prevent the playback video from being interrupted.

  The data processor 36 supplies the DVD recording data output from the encoder unit 50 to the disk drive 35 under the control of the microcomputer block 30, takes in the DVD playback signal reproduced from the optical disk 1001 from the disk drive 35, The management information recorded in 1001 is rewritten, or the data (file or video object) recorded on the optical disc 1001 is deleted.

  The microcomputer block 30 includes an MPU (micro processing unit) or CPU (central processing unit), a ROM in which a control program and the like are written, and a RAM for providing a work area necessary for executing the program.

  The MPU of the microcomputer block 30 receives operation information from the key input unit 47 and uses the RAM as a work area based on a control program stored in the ROM to detect a defect location, detect an unrecorded area, and record recording information. Position setting, UDF recording, AV address setting, etc. are executed.

  The microcomputer block 30 includes an information processing unit necessary for controlling the entire system, and includes a copy information detection / setting unit, a directory detection unit, and a VMG management information creation unit.

  Among the execution results of the MPU, contents to be notified to the user of the disk drive 35 are displayed on the display unit 48 of the DVD video recorder, or displayed on the monitor display (not shown) on the OSD (on-screen display).

  The timing at which the microcomputer block 30 controls the disk drive 35, the data processor 36, the encoder unit 50, and / or the decoder unit 60 can be executed based on the time data from the STC 38. Recording and playback operations are normally executed in synchronization with the time clock from the STC 38, but other processing may be executed at a timing independent of the STC 38.

  The decoder unit 60 separates and extracts each pack from video information having a pack structure, a memory 63 used when pack separation or other signal processing is performed, and main video data (video pack) separated by the separator 62. The V decoder that decodes the sub-picture data (sub-picture pack contents) separated by the separator 62, and the audio data (audio pack contents) separated by the separator 62. The main video data obtained from the decoder group 64 by the A decoder and the main video data obtained from the V decoder are appropriately combined with the sub video data obtained from the SP decoder, and the menu, highlight button, subtitle and other sub-videos are superimposed on the main video and output. A video processor 66 is provided.

  The output of the video processor 66 is input to the video mixer 71. In the video mixer 71, text data is synthesized. The video mixer 71 is also connected to a line that directly takes in signals from the TV tuner 44 and the A / V input unit 42. A frame memory 72 used as a buffer is connected to the video mixer 71. When the output of the video mixer 71 is a digital output, it is output to the outside via an interface (I / F) 73, and when it is an analog output, it is output to the outside via a DAC 74.

  When the output of the A decoder is a digital output, it is output to the outside via the interface (I / F) 75, and when it is an analog output, it is converted into an analog signal by the DAC 77 via the selector 76 and output to the outside. The selector 76 can also select the output from the ADC 52 when the signal from the TV tuner 44 or the A / V input unit 42 is directly monitored by the select signal from the microcomputer block 30. The analog audio signal is supplied to an external component (2-channel to 6-channel multi-channel stereo device) (not shown).

  In the above apparatus, the flow of the video signal will be briefly described as follows.

  First, the input AV signal is digitally converted by the ADC 52. The video signal is input to the V encoder, the audio signal is input to the A encoder, and character data such as text broadcast is input to the SP encoder. The video signal is subjected to MPEG compression, the audio signal is subjected to AC3 compression or MPEG audio compression, and the character data is subjected to run length compression.

  The compressed data from each encoder is packetized so as to be 2048 bytes when packed, and input to the formatter 56. In the formatter 56, each packet is packed, further multiplexed, and sent to the data processor 36.

  Here, the formatter 56 creates an RDI pack based on the aspect information and places it at the head of the video object unit (VOBU). The data processor 36 forms an ECC block every 16 packs, adds error correction data, and records the output on the optical disc 1001 via the disc drive 35. Here, since the disk drive 35 is in a seek state or a track jump or the like, in the busy state, the disk drive 35 is put in the temporary storage unit 37 (for example, the HDD buffer unit) and stored in the DVD-RAM drive unit (disk drive 35). You will wait until you are ready.

  Further, the formatter 56 creates each segmentation information during recording, and periodically sends it to the MPU of the microcomputer block 30 (information at the time of GOP head interruption, etc.).

  The segmentation information includes the number of VOBU packs, the end address of the I picture from the beginning of the VOBU, the playback time of the VOBU, and the like.

  At the same time, the aspect information is sent to the MPU at the start of recording, and the MPU creates VOB stream information (STI). Here, the STI stores resolution data, aspect data, and the like, and at the time of reproduction, each decoder unit is initialized based on this information.

  In the recording / playback DVD, one video file is recorded on one disc.

  Here, in a real-time recording / playback apparatus using a DVD, a point to be noted is that when data is accessed, it continues at least in order to continue playback without interruption during the access (seek). Sectors are needed. This unit is called CDA (Contiguous Data Area). That is, the data size is determined in advance to realize seamless reproduction.

  This CDA is advantageously in units of ECC blocks. Therefore, the CDA size is a multiple of 16 sectors, and the file system performs recording in units of CDA. However, in this case, if there is not enough free space of CDA size in the disk, a short sector used by another file is allowed to enter the CDA. Thereby, recording can be performed in units of CDA.

  FIG. 2 shows the hierarchical structure of the video manager (VMG), in which the system for managing the data reproduction order is shown in detail.

  The playback order of data recorded in a video file is defined by a program chain (PGC) as shown in FIG. In the program chain (PGC), a cell (Cell) is defined, and in the cell (Cell), a VOB to be reproduced is defined. The part where the specific information of this PGC is recorded is the program chain information (PGCI) part in the VMG file. There are two types of PGCI, one is an original PGCI (ORG_PGCI), and the other is a user-defined PGC table (UD_PGCIT).

  FIG. 3 shows the contents of the program chain information table (PGIT) in the program chain information (PGCI) in more detail. The program chain information includes a program type (PG_TY) indicating whether or not a program corresponding to this program chain can be erased, the number of cells in this program, primary text information (PRM_TXTI) described in this program, and text information. Pointer number (IT_TXT_SRPN) and representative image information (REP_PICTI = cell number and pointer in the cell) are described.

  FIG. 4 also shows hierarchically the movie AV file information table (M_AVFIT) in the video manager (VMG). The information in this table includes the number of recorded VOBs (programs), the number of audio and sub-picture streams corresponding to each VOB, and the attributes of each VOB (television system, aspect ratio, etc.) stream information (M_VOB_STI) It is recorded as. Further, as M_AVFI, information indicating whether the VOB is reproducible or temporarily erased and date / time information (recording time) when the VOB is recorded are described as general information. Further, as individual information, a search pointer for each VOB and system clock information as information (SMLI) for continuously reproducing a plurality of VOBs are described. Furthermore, VOBU time map information (TMAPI) in the VOB is described. The time map information can be used when special reproduction or the like is performed.

  Here, the recording / reproducing apparatus is provided with a chapter creation guide function. This chapter creation guide function is performed by visually confirming the first and last images of the chapter on the display unit (display) while reproducing the actual title (program) when dividing the title into a plurality of chapters. It is what I did.

  First, the screen when creating a chapter will be described. When the remote controller 80 shown in FIG. 5 is operated and an editing navigation key (editing navigation key) is pressed, as shown in FIG. 6, “part”, “chapter”, and “playlist” indicating the target title on the screen are displayed. Appears, move the cursor to the chapter item and press the Enter key.

  Then, the screen shown in FIG. 7 appears. On this screen, a moving image reproduction area 81a for displaying the selected title as a moving image is secured, and a thumbnail display area 81b for displaying a thumbnail that is a representative image at the head of the chapter is secured. Further, a button area 81c for chapter registration is secured. Furthermore, a bar-shaped display area 81d is secured in order to easily understand how many chapters have been created in the title. Further, an area 81e for displaying the target medium, an area 81f for identifying and displaying whether the program is an original (corresponding to OPGC) or a playlist set by the user (corresponding to UDPGC), and a moving image reproduction area 81a An area 81g or the like indicating the current position of the displayed image by the elapsed time from the top of the program is secured.

  In the bar-shaped display area 81d, marks corresponding to the number of chapters existing in the program are added and displayed. In the example of the figure, a state in which six chapters are created is shown. Accordingly, when a plurality of thumbnails are displayed in the thumbnail display area 81b, thumbnail numbers are displayed in accordance with the thumbnails. In the figure, an example in which the second to sixth thumbnails are displayed is shown. Although the first thumbnail is not shown in the figure, this is because the first thumbnail is hidden by scrolling due to the limitation of the display area.

  Further, in this embodiment, a chapter can be released by deleting a thumbnail by giving a delete command in a state where a plurality of thumbnails are displayed and the cursor is placed on a desired thumbnail. . In this case, the chapter corresponding to the deleted thumbnail can be combined with the previous or subsequent chapter.

  FIGS. 8A to 8C show transitions of screens when chapters are created. First, as shown in FIG. 8A, the title is played back at high speed forward or high speed in the moving image playback area 81a, and when it is near a desired image (for example, near a chapter boundary), for example, a frame advance operation is performed. Then, when the image of the chapter boundary (first head) portion is reached, the cursor is moved to “divide” (button area 81c) and the enter key is operated. Then, as shown in FIG. 8B, a thumbnail that is the first image of the chapter is created, and the first thumbnail (numbered) is displayed in the thumbnail display area 81b.

  Further, high-speed forward feeding is performed, and when the chapter boundary image is reached, the cursor is moved to “divide” (button area 81c) and the enter key is operated. Then, as shown in FIG. 8C, the second thumbnail corresponding to the chapters after the division point is created, and the end of the first chapter is determined. Thus, in this recording / reproducing apparatus, chapters can be created one after another.

  FIG. 9 shows the transition of the screen when the chapter created as described above is deleted. For example, as shown in FIG. 9A, when deleting the chapter corresponding to the thumbnail B in a state where four thumbnails A to D are displayed in the thumbnail display area 81b, FIG. As shown in (c), move the cursor to the position of thumbnail B, and operate the quick key on the remote controller 80. “Delete” is displayed on the screen. Move the cursor to that area and operate the enter key. Then, as shown in FIG. 9D, the thumbnail B is deleted, and the interval between the thumbnails A and C is reduced.

  When combining the divided chapters, move the cursor to the corresponding thumbnail and operate the quick key on the remote controller 80. The screen displays “Combine with previous chapter / Combine with subsequent chapter” on the screen. Just move the cursor to the required area and operate the enter key.

  FIG. 10 shows a flowchart summarizing chapter creation operations. First, when chapter creation is requested and started (step S11), the microcomputer block 30 displays a moving image reproduction area 81a, a thumbnail display area 81b, a button area 81c, and the like on the screen in step S12.

  Next, the microcomputer block 30 searches for entry points in the designated program (title) in step S13, and acquires a thumbnail corresponding to the search result from the thumbnail data table in step S14. If the result of the search in step S15 is that there is already a chapter in the designated program, the microcomputer block 30 displays the thumbnail in the thumbnail display area 81b.

  Thereafter, the microcomputer block 30 enters a key input acceptance state in step S16, and determines whether the operated key is a key relating to a reproduction operation or a split button in step S17. If it is a key related to the reproduction operation, the microcomputer block 30 reproduces / stops the moving image in the moving image reproduction area 81a in a mode corresponding to the operated key in step S18, and returns to the processing in step S16.

  If the button is a split button in step S17, the microcomputer block 30 creates an entry point at the position of the PTM (presentation time stamp) from the encoder unit 50 in step S19. In step S20, the microcomputer block 30 Create still image bitmap data from video.

  Thereafter, the microcomputer block 30 registers the created bitmap data in the thumbnail data table in step S21, displays the still image in the thumbnail display area 81b in step S22, and returns to the process of step S16.

  FIG. 11 shows an example of the thumbnail data table. The thumbnail data table is divided into a header portion in which program numbers, cell numbers, entry point numbers, pointers to thumbnail bitmap data, and the like are arranged, and a data portion for storing actual thumbnail bitmap data. The search is performed by comparing the header portion of the thumbnail data table with the target program number, cell number, and entry point number.

  The present invention is not limited to the above-described embodiment, and can be variously modified and implemented without departing from the scope of the invention.

  As described above in detail, according to the present invention, it is possible to provide a recording / reproducing apparatus with a chapter creation guide function capable of easily creating chapters while confirming them on the screen.
