As previously mentioned, embodiments of the invention only can not read out the way that row is play with the video data that will before store like traditional processing mode again in memory storage, will cause having the user who views and admires real time content (live content) demand must stand on the significant time and delay (even may reach the several seconds), handle path (being aforesaid first path) and provide a vision signal, it is after carrying out a pre-process to vision signal, do not experience compressed encoding operation-＞write hard disk-＞read hard disk-＞situation of decompression decode operation under, directly vision signal output is play, guaranteeing that the user can watch the video content of " in real time real ", and need not stand because compression coding and decoding operation and extra time that access hard disk spent.Such function under the situation that the user takes notice of for the demand of real-time rating very much (for example view and admire on-the-spot motion race or make the first showing of a film before the public), has remarkable meaning especially.
Embodiments of the invention are except first path that real-time play is provided, second path that vision signal after the pre-process is compressed and stored still is provided, this is to consider the user except the demand that the rating real time content is arranged, and also has simultaneously the demand of suspending at any time that rating is play again again and/or reversing (rewind) or search (seeking) for the content of having play.For instance, viewing and admiring as a user in the process of a real time content, suspending rating (for example press and suspend button " PAUSE ") when planning to continue rating after a period of time, if it does not wish to miss the details at any a moment in this content, then can carry out suitable operation (for example press again and play button " PLAY ") to digital image device, this moment, microprocessor 120 promptly can produce a corresponding control signal CTRL, in hard disk 150, read out and through the vision signal behind the MPEG2 decode operation to choose (with multiplexer 228 expression), so that the content of the image that is played back when and then before having suspended.Similarly, when having for the content of having play, a user reverses (rewind) or when searching the demand of (seeking), it can carry out suitable operation (for example press reversing button " REWIND " or operate and fly shuttle knob " SHUTTLE ") to digital image device, this moment, microprocessor 120 promptly can produce a corresponding control signal CTRL, in hard disk 150, read out and through the vision signal behind the MPEG2 decode operation to choose, and according to the pairing time point of user's operation, output has the play content of orthochronous stamp.
Certainly, after above-mentioned various operations, the user also can select to get back to the rating of real time content at any time, as long as in addition suitable operation (for example pressing real-time play button " LIVE "), this moment, microprocessor 120 promptly can produce a corresponding control signal CTRL, choosing the vision signal of institute's generation after the pre-process, uncompressed and storage once more, and real-time play content once more.
It should be noted at this, though in the above-described embodiments, TV decode operation 210 and video coding operation 230 are respectively to realize with the television decoder circuit of special-purpose (dedicated) and television encoder circuit, and video pre-process 222, the MPEG2 encoding operation, and the MPEG2 decode operation is to cooperate the computing of software or firmware program code to realize by microprocessor 120, but those who familiarize themselves with the technology all should understand, the present invention is not as limit, and above-mentioned every processing operation and the function that is provided all can be with special hardware circuits, software program code, or above the two mix and match is done in fact.Moreover, though in the present embodiment, digital image device 100 includes the television encoder 130 that is used for converting analog video signal the television decoder 110 of digital video signal to and is used for digital video signal is converted to digital video signal, but the present invention is not as limit, the vision signal that is sent in video-audio data source 140 is exactly under the situation of digital format originally, television decoder 110 is inessential assembly, and the display device 160 in the rear end has digital signal interface and can accept under the situation of digital video signal the also inessential assembly of television encoder 130.As for memory storage 150, though be example with hard disk built-in or that be external in digital image device 100 in the present embodiment, the present invention is not as limit, and other also is the one example such as the remote equipment that connects by network.Though again in the present embodiment, digital image device 100 can carry out compression of images to it earlier when vision signal is stored, to save access frequency range or storage space, but the present invention is not as limit, in other embodiments, also can not compress and direct being stored in the memory storage 150 of inciting somebody to action vision signal.
Please consult Fig. 3 again, it is that display digit image device 100 is stored in the hard disk 150 or via network or other data source and receives, and belongs to the synoptic diagram of a plurality of image files of same content (as same film).As shown in Figure 3, a video data that belongs to same content is stored as five files in regular turn, be respectively " video.001 " of 2Gbyte, " video.002 ", " video.0 03 ", " video.004 ", " video.005 " of 1Gbyte of 2Gbyte of 0.5Gbyte of 1Gbyte, institute's canned data among the video.002 wherein, be the latter who on the content time sequencing, continues at video.001, and institute's canned data among the video.003, be the latter who continues at video.002 on the content time sequencing, all the other by that analogy.So this video data can be stored as a plurality of files, may be because employed file system (as FAT32) or employed coding techniques (as DivX) to due to the added restriction of single file size.And these a plurality of files, may be (for example to transmit) when sending promptly to present the form of respective files or when microprocessor 120 carries out compressed encoding by network from data source, beginning is compressed according to time sequencing and is stored as a plurality of respective files, and is stored in the middle of the hard disk 150.
In an embodiment of the present invention, digital image device 100 is when receiving or forming the above-mentioned a plurality of image file that belongs to same content, except being stored in above-mentioned each image file in the hard disk 150, more can produce and store an index data structure (index datastructure) that is used to refer to described image file, as shown in Figure 4, it is to show according to the index data structure 400 of one embodiment of the invention and the synoptic diagram of the corresponding relation between the above-mentioned image file.In Fig. 4, index data structure 400 includes many data (entry), wherein, each data be correspond respectively to aforementioned a plurality of image file one of them, for example the first stroke data 410 are corresponding to video.001, and second data 420 is corresponding to video.002, and all the other by that analogy.Please consult Fig. 5 again, it is to show according to one embodiment of the invention the synoptic diagram of the content that is comprised in the index data structure 400 among Fig. 4.In index data structure 400, corresponding to each data, it includes one " file name " field 460, one " file size " field 470 and optionally includes one " accumulated document size " field 480.
Wherein, " file name " field 460 is used for going up order according to the time of this video data content, indicate the filename of each respective files, for example in Fig. 5, " file name " field of the first stroke data is " video.001 ", " file name " field of second data is " video.002 ", and the rest may be inferred, and " file name " field of the 5th data then is " video.005 ".The file size that 470 of " file size " fields are used to refer to corresponding file name in each data why, for example in Fig. 5, " file size " field of the first stroke data is that the size of video.001 is 2Gbyte, " file size " field of second data is that the size of video.002 is 1Gbyte, the rest may be inferred, and " file size " field of the 5th data is 1Gbyte for the size of video.005 then.And if " accumulated document size " field 480 is adopted in selection, then this field be used for storing since the first stroke data accumulative total file size why, for example in Fig. 5, " accumulated document size " field is stored 2Gbyte, 3Gbyte, 3.5Gbyte, 5.5Gbyte, 6.5Gbyte in regular turn.
In the present embodiment, digital image device 100 can be in due course a little, for example during initialization, or when opening specific file directory (file directory), the image file of being stored is searched, according to the result who searches find out have same file characteristic each file (for example in the present embodiment, all beginnings are the file of " video "), the relevant information of these files is inserted in its index data structure that produces 400 again, and index data structure 400 is temporarily stored in (for example a DRAM (Dynamic Random Access Memory) is not shown among the figure) in the middle of the storage space.Yet disclosed herein straw line data structure produces and the method for keeping not is a restrictive condition of the present invention, other straw line data structure that the people knew or innovated of haveing the knack of this technology produces and keeps method, also can be applicable in the middle of the present invention, for example, the form that this index data structure can also a file is stored.Moreover, in the index data structure 400 in the present embodiment except the information that includes each field as mentioned above, more can include again such as reception incomer's information such as signal format (for example its for NTSC or PAL), video bit rate (video bitrate), video length (for example how long or what picture frames), the usefulness of the search location during in order to broadcast.
Because the digital image device 100 according to embodiments of the invention is the index data structure 400 that produce and keep as shown in Figure 5, digital image device 100 can be by reading institute's canned data in the index data structure 400, add simple index computing, the video content that can very promptly find present institute desire to play is which position that is positioned at which central file of described a plurality of image file, and then this position of the specified this document that arrives of access, correctly to play this video content.See also Fig. 6, it is to show according to one embodiment of the invention the corresponding relation synoptic diagram between the video content of being play during operand word image device 100 and this a plurality of image files.In Fig. 6, it is the operation-interface 510 of display digit image device 100, operated from a distance interface 520, and display frame 530, and in the present embodiment, operation-interface 510 include control of video play common operating function, for example " broadcast " (play), " reversing " (rewind), " the fast commentaries on classics " buttons such as (fast forward), or other function, and on the operated from a distance interface 520 (a for example telepilot), except foregoing various operating knobs, more include one can be used for searching out fast the video content segments desiring to view and admire fly shuttle knob (shuttle).In Fig. 6, more shown a time shaft cross bar (time bar) 540, it is noted that, time shaft cross bar 540 can be a part that in fact belongs to the play operation interface of digital image device 100, and can be subjected to the content time point that drag operation (drag) is play with decision institute desire, perhaps it also can only be used for representing the time indicator (timeindex) of the video content of being play in the present embodiment, and in fact is not presented in the operation-interface.
The video content of playing when the institute desire is by normal play the time (for example playing button when the user presses), digital image device 100 promptly can continue to keep a time count value, be used to refer to and hold time point within playing at present, by constantly increasing progressively this time counting value, this video content promptly is able to be played back in regular turn.Because institute's data bit stored has a corresponding relation between putting in the play time of this video content and the described image file, as shown in Figure 6, the content pointers (content index) 550 that is used as the time shaft cross bar 540 of time index and is used for representing the Data Position in each file has relation one to one.Therefore, this time counting value that digital image device 100 is kept can be scaled pairing Data Position, and again via the index data structure among Fig. 5 400 being searched and comparing, can determine present in progress time point, its video content is which position in which file in these a plurality of image files.
For instance, if the user presses when playing button, the time point of being play is positioned at one hour 25 minutes parts of this video content, the conversion of elapsed time point/data volume, and afterwards to the search of index data structure 400 and comparison (for example " file size " field 470 is searched and relatively), can get up till now the Data Position that time point corresponded to is positioned between (2Gbyte+1Gbyte+0.5Gbyte)=3.5Gbyte and (2Gbyte+1Gbyte+0.5Gbyte+2Gbyte)=5.5Gbyte (perhaps, also can directly search and comparison) " accumulated document size " field 480, that is be arranged in this file of video.004, and its definite position in this document also can draw according to a reduction formula or proportionate relationship, so, digital image device 100 promptly is able to video data and the broadcast that access correctly is arranged in video.004.And along with video content broadcasts in regular turn, when entering into next file institute data bit stored, puts the time point of being play (for example two of this video content hours very part), after the conversion and search and comparison of same elapsed time point/data volume to index data structure 400, also can be very promptly the Data Position that time point corresponded to up till now be arranged in this file of video.005, with and accurate location, digital image device 100 similarly is able to access correctly and is arranged in the video data of video.005 and broadcasts.
And when the video content of being play being carried out as operations such as reversing, searches, for example press the cursor on shuttle knob or the towing time shaft cross bar 540 of flying on reversing button, the remote controller 520, more can show benefit of the present invention, especially on reversing of striding file or seek operations.In previous identical example, promptly the time point of being play is positioned at one hour 25 minutes parts of this video content, and its pairing Data Position is arranged in this file of video.004, result as if this time reversing or seek operations, make the time point of being play drop on one hour five minutes parts of this video content, the then conversion of elapsed time point/data volume, and after the search and comparison to index data structure 400, equally can be very promptly the Data Position that time point corresponded to up till now is arranged in this file of video.003, with and accurate location, like this then digital image device 100 similarly is able to access correctly and is arranged in the video data of video.003 and broadcasts.It should be noted that especially, in in this example the reversing or seek operations, the video data of 100 accesses of digital image device is former to be taken out from video.004 before this, then become from video.003 finally and take out, so stride file and get the operation of depositing video data, the file of striding of especially reverse (backward) is got the operation of depositing video data, in conventional practice, belong to and to reach, but generation and use by in the embodiments of the invention the index data structure that disclose and illustrate, then only need some simple arithmetic operations of searching file content and comparison, can reach easily.
It is noted that at this, though in the above-described embodiments, the information of index data structure 400 storage file sizes (or accumulated document size), but those who familiarize themselves with the technology also should understand, the present invention is not as limit, can also store the mode of the time stamp (time stamp) that corresponds to the initial and/or termination locations of file content in the index data structure 400 and handle, also can reach purpose of the present invention.Moreover, owing to be to come arrangement information corresponding to the mode of a file name and file size (or time stamp) thereof in index data structure 400 with each data, so in the digital image device that uses index data structure of the present invention, a plurality of image files that belong to same content (a for example same film) that it is stored, its filename does not need to have any specific stroke or lexicographic order, digital image device 100 only must can find correct image file by the search to index data structure 400.
In sum, exposure according to embodiments of the invention, digital image device only must produce and keep a very little comparatively speaking index data structure, what can reach no seam (seamless) strides search of file video and play operation, and can be as prior art, cause the user to pause or audiovisual experience that interruption etc. is unhappy or can't stride the reverse search of file or problem such as play operation striding must stand when file is play.In addition, use digital image device as the described index data structure of embodiments of the invention, the operation-interface of the application software of Pei Heing also can be designed to only this index data structure be managed and show with it, thus, it is unit (content-based) that the user just only need touch with " content " in the interface of this kind application software, but not be the information of unit (file-based) with " file ", this will make the interface management of application software more succinctly reach intuition.
