Definitions
- the present invention relates to a method of managing and reproducing additional audio files of an interactive optical disc. More specifically, the present invention provides a means for play control of additional audio data of various contents associated with main video data by reading out from the interactive optical disc or receiving through the Internet.
- DVDs are in wide use. DVDs are being commercialized as high-capacity recording media capable of recording high-quality video data for many hours as well as digital audio data.
- DVD includes a navigation data recording area for recording navigation data needed for play control of said video data and a data stream recording area for recording digital data streams such as said video data.
- a common DVD player reads out navigation data recorded in said navigation data recording area and stores the navigation data in the memory within the apparatus; thereafter, by using the navigation data, the DVD player carries out DVD playback operations whereby video data recorded in said data stream recording area can be read out and played.
- an owner of said DVD player can not only play and watch high-quality video data recorded in said DVD for many hours, but also select and use various functions provided by said DVD.
- IDVD Interactive DVD
- the specification is supposed to include a means whereby additional audio data of various contents associated with video data read out and played from said IDVD can be received from a content providing server connected through the Internet and subsequently reproduced.
- an efficient means for play control of additional audio data read out from said IDVD or provided from a content providing server has not been established yet, which needs to be provided immediately. 3.
- the present invention is directed to provide a means for managing . and reproducing additional audio files of IDVD. More specifically, the present invention provides a means whereby additional audio data of various contents associated with main video data read out and played from an optical disc such as IDVD are read out from the optical disc or received from a content providing server connected through the Internet; and can be reproduced efficiently in association with said main video data.
- a method of managing additional audio files of an interactive optical disc comprises: recording and managing additional audio data associated with main video data of the interactive optical disc as a file of a prescribed format; and recording and managing file information about said additional audio data and buffering information about the additional audio data within said file of a prescribed format .
- a method of reproducing additional audio data of an interactive optical disc comprises: allocating a buffering area to temporarily store additional audio data associated with main video data of the interactive optical disc; searching for and interpreting file information and buffering information about additional audio data to be stored in said buffering area; and according to said interpreted file information and buffering information, storing the additional audio data read out from said interactive optical disc or provided from a content providing server in said buffering area with subsequent reading out and reproduction thereof.
- Fig. 1 illustrates the structure of an interactive optical disc apparatus according to the present invention
- Fig.2 illustrates a state where ENAV buffer of an interactive optical disc according to the present invention is allocated in a normal area or partial update area
- Figs.3 and 4 illustrate associated states between INIT, READY, FILL, PLAY, PAUSE, and DRAIN operation carried out in an optical disc apparatus according to the present invention
- Figs. 5 and 6 illustrate embodiments of a method of managing and reproducing additional audio files of an interactive optical disc according to the present invention.
- Fig. 1 illustrates the structure of an interactive optical disc apparatus according to the present invention.
- An IDVD player includes an ENAV engine 100 comprising a network manager 10, ENAV buffer 11, ENAV parser 12, element decoder 13, ENAV interface handler 14, A/V renderer 15, audio manager 16, and interpreter 17; and a DVD-Video playback engine 200 operating in association with said ENAV engine .
- the said ENAV buffer 11 can be assigned to a single normal area (NA) occupying a predetermined recording size (for example, 36 Mbytes) .
- NA normal area
- the said ENAV buffer 11 stores audio data of ENAV contents transmitted from a content providing server 300 connected through the Internet or read out from an interactive DVD 400.
- the said audio manager 16 through said ENAV interface handler 14 carries out a series of operations for storing and play control of audio data against said ENAV buffer 11. For instance, as shown in Fig.
- the said audio manager 16 allocates a PUA within said ENAV buffer 11 through the interface with said ENAV interface handler 14 and stores audio data of ENAV contents within said PUA, which subsequently carries out a series of INITIAL, READY, FILL and PLAY operation for reading out and playing the audio data.
- the said audio manager 16 upon request from a user, carries out a series of PAUSE and DRAIN operation for stopping playback of audio data read out from said ENAV buffer 11 or deleting audio data stored in said ENAV buffer.
- the PUA within said ENAV buffer 11 is allocated by an arbitrary recording size (AllocPUAO) .
- NA and PUA are allocated separately, each having an arbitrary recording size. Otherwise, only a single NA is allocated without PUA.
- a series of FILL operations are carried out wherein audio data of ENAV contents are loaded into PUA allocated within said ENAV buffer 11.
- the said audio manager 16 when storing audio data amounting to the initial buffering size (Initial_fullness) is completed, for example, when the initial buffering size is 100K under the condition that the recording size of said PUA is assigned as 512K, on storing audio data of lOOKbytes in said PUA, the said audio manager 16 carries out PLAY operation reading out and playing audio data of the 10OK byte.
- network connection is lost (Network EOF)
- DRAIN operation is carried out, during which audio data stored in said ENAV buffer are deleted.
- the said audio manager 16 then carries out INITIAL operation allocating PUA of 512 Kbytes within said ENAV buffer through said ENAV interface handler (Step 1) .
- the said interpreter 17 interprets that buffering of audio data in PUA and carrying out playback operation on completion of buffering 100 Kbytes of the audio data in the PUA have been specified, after which transmits a corresponding command to said ENAV interface handler 14. According to the command, the said audio manager 16 then carries out READY (Step 2) , FILL (Step 3) , and PLAY (Step 4) operation in sequential order through said ENAV interface handler 14. On the other hand, as shown in Fig.
- the said interpreter 17 interprets that the file name of audio data is “soundl .mp3” ; the type of audio data is “mp3” ; and the proper ID is “click” .
- parameter name "buffer”
- value "normal area”
- parameter name "loop”
- value "true”
- the said interpreter 17 interprets that buffering audio data in the NA and pre-loading of audio data thereto have been specified, after which subsequently transmits a corresponding command to the said ENAV interface handler 14.
- the said audio manager 16 then carries out READY (Step 12) , FILL (Step 13) , and PLAY (Step 14) operation in sequential order through the said ENAV interface handler 14.
- READY Step 12
- FILL Step 13
- PLAY Step 14
- the audio data pre-loaded to the NA in said manner can be reproduced by a particular sound producing the sound of click effect.
- determination of the buffering area for storing said audio data can be selectively decided according to the author who authored the corresponding audio file or recording size of audio data.
- a method of managing and reproducing additional audio files of an interactive optical disc according to the present invention is a very useful invention which enables additional audio data of various contents read out from the optical disc or received from a content providing server connected to the Internet to be reproduced efficiently in association with main video data.
