Embodiment
In order to further illustrate the present invention, be described further below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of CD captioning synchronization management method of the present invention and device thereof comprise: light picker 11, read the data of CD D record; Rf processor 12, the data read by light picker 11 increase output frequently or are detected by the fat signal read from CD D; The data exported from rf processor are carried out signal transacting and are transported to display equipment by signal processor 13; Microprocessor 14, carries out the overall controls such as the data conversion controlling above-mentioned signal processor 13; Storer 15, various process data required in storage microprocessor 14 and be also included in microprocessor 14 control under, the sliding motor 17 controlling mobile light picker 11 and the rotary engine 18 driving CD 0 to rotate, and light picker 11 is carried out to the servomechanism 16 of tracking servo operation and focusing operation control.Wherein, described storer 15 is the subtitle files described in storage is read from the CD D recording subtitle file in certain posting field; Described microprocessor 14 exports actual caption data according to the caption information implementing to store.
There is the optical disc apparatus of the present invention of structure described above, comprise the subtitle file of the contents such as all caption datas, caption data reproduction time and caption data size, be recorded in certain caption information posting field of CD D, when above-mentioned CD D is inserted into, optical disc apparatus of the present invention just reading is recorded in the subtitle file of word power information recording area and is stored in storer 15, then when playing CD D, according to the subtitle file being stored in above-mentioned storer 15, export corresponding caption data together to the video/audio data play simultaneously.
Fig. 3 is the operational flowchart of caption data management method in optical disc apparatus of the present invention.As shown in the figure, a kind of CD captioning synchronization management method of the present invention and device thereof, be applicable to when certain posting field records the dvd playback of a series of caption information.
In addition, Fig. 4 is the caption data record format figure of CD of the present invention.In above-mentioned CD, as shown in the figure, certain posting field of CD is separately recorded in for the subtitle file (captionfile) of Play Control caption data and audio/video title data (title).Above-mentioned subtitle file is made up of multiple caption data block (captiondatablock), above-mentioned caption data block is by a series of caption datas with continuity: caption data #1, caption data #2---caption data #N (captiondata#1, captiondata#2---captiondata#N) and corresponding each caption data head (header) form.Above-mentioned head portion comprises reproduction time information (reproducingtime) and the data size information (datalength) of caption data.
The operating process (simultaneously see Fig. 1,3) of caption data management method in optical disc apparatus of the present invention:
Flow process starts;
S11: as mentioned above, includes the subtitle file of the information such as caption data, the reproduction time of this caption data and this caption data size that will play, is recorded in posting field certain on CD D record surface, when this CD is inserted into, identifies CD D;
S12: the above-mentioned subtitle file of reading process is also stored in the middle of storer 15, as mentioned above after the data of the subtitle file of reading process are stored in storer 15 certain area, performs corresponding operating according to user command;
S13: if the operational order of above-mentioned user input is when being play command, optical disc apparatus will drive above-mentioned CD D, reads video, voice data that record surface records, and carries out signal transacting, is play and is transported to picture or loudspeaker get on.
S14: then, optical disc apparatus is carrying out in the process of above-mentioned a series of play operation to CD D, the temporal information that the subtitle file that can continue the actual play time of more above-mentioned CD D and above-mentioned storer 15 store is play,
S15: according to the result compared, judges whether to exist in the actual play process of CD D the caption data needing to export, if there is not the caption data needing to export in the actual play process of CD, then optical disc apparatus is still in the playing flow of S13;
S16: if need playing caption data in the actual play process of above-mentioned CD, just reads corresponding caption data, the above-mentioned caption data through signal transacting is input to current picture in the middle of storer 15:
Whole flow process terminates.
In addition, as previously mentioned, when carrying out normal play, when needing according to the requirement of user the track skipping certain area, the track in this region will be crossed at a high speed, now, the reproduction time of the subtitle file stored in the dvd playback time of current posting field reading of skipping and storer 15 is compared mutually, if the starting point after current hops starts to exist the caption data requiring to play, just carry out the playback process of corresponding subtitle data.
In addition, when carrying out normal play as above, after user inputs navigation commands, just the track of respective regions will be carried out to high speed retrieval.Now, the reproduction time of the subtitle file stored in the CD D reproduction time of the current posting field reading retrieved and storer 15 is compared mutually, starting point after current hops starts, if there is the caption data requiring to play, just carries out the playback process of corresponding subtitle data.
In addition, carry out in the process of foregoing normal play, when user inputs slow play order, while slow play, the caption data that retrieval Current demands is play also is play.
Again in addition, because just carried out reading process and stored the caption information recorded in certain posting field of CD D when CD D has just inserted identification, so, optical disc apparatus as above can according to including the above-mentioned certain words having stored caption data, and the starting point playing output video data or corresponding subtitle data starts immediately to move.
Although the present invention describes with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, should understand and wherein can make various changes and revise and not depart from the present invention in a broad sense, so not as limitation of the invention, as long as in spirit of the present invention, the change of the above embodiment, distortion all will be dropped in the scope of claims of the present invention.
