Description
Technical field
The present invention relates to a kind of recording medium (record medium), can high density (high density) mode recording of video (video) data and audio frequency (audio) data.The invention still further relates to a kind of digital video frequency film random selection pre-looking (preview) method, its audio, video data random selection pre-looking that will be stored in recording medium plays back.
Background technology
In the field of optical digital disk medium, its evolution is by simple playing back music, as audio frequency cd (audio compact disk, CD), develop into and can play the program that has comprised audio frequency and video, as laser disc record (laser disc), video disc (video compact disk, VCD), progressive again to the digital video video disc that has added menu function (digital video disk, DVD).
In the VCD technology formerly, because the data structure (data structure) in the disk medium is simple, media playing apparatus is when play menu (menu), and button (button) only has a kind of pattern, i.e. start-up mode (activated mode).
Figure 1A is the data structure diagram of an existing VCD.Log form (entry table) 100 comprises a plurality of login points (entry point) 101～10N, each login point all has track (track) 111～11N of a correspondence, and each track 111～11N has comprised with a plurality of video packets (video pack) 111b and audio pack 111c (audio pack) headed by login video packets (entry videopack) 111a.
Figure 1B is the digital video frequency film player method of VCD technology.The first initialization of media play system (reproducingsystem) (initialization) is in step 151, with the initialization of single resolution video decoder implementing.Then, in step 152, read log form.After initialization is finished, promptly wait for user's enabling signal.In step 153, media play system receives user's enabling signal.Secondly, in step 154, find the login point.In step 155, the just mobile reading device of media play system is to the login point that corresponds to this enabling signal.Then, in step 156, read all stored audio frequency and video bags in the track that corresponds to this login point.At last, in step 157, with all audio frequency and video bag decoding.
The shortcoming of VCD technology is that the resolution (resolution) of all images data is identical, only can play the background film of single resolution when handling menu.In addition, button only has start-up mode, and the user directly reads the original video-audio data of logining point after starting button, can't preview.
In the present DVD technology,, but still have the ability not capture part though menu function is powerful.Because the data structure of DVD is than the VCD complexity, media play system is when play menu, and button has two kinds of patterns, i.e. preference pattern (selected mode) and start-up mode.Media play system can be read the key information (button information) and highlight information (highlight information, the sub-captions image (sub-picture) corresponding with it of choosing button earlier from DVD.The use of key information and highlight information is to allow media play system obtain choosing coordinate position, color and starting command (command) of button or the like, and sub-captions image then is intended for the figure of button.Receiving the signal that is transmitted by the external world when media play system is that the sub-captions image that media play system is only chosen representative button is superimposed on the background pages according to the coordinate position in key information and the highlight information when selecting signal.And when media play system is received the enabling signal that is transmitted by the external world, then can carry out the starting command of choosing button at that time.
Fig. 2 is the data structure diagram of the method for previewing of an existing DVD.Key information 202 among the highlight information 201 comprises pattern 203 and starting command 204, and pattern 203 can have two kinds of selections (option): first kind is that preference pattern adds start-up mode, and second kind is to have only start-up mode.DVD could carry out starting command 204 under start-up mode, i.e. N fragment of preview film, and read the initial address 21N of N fragment of preview film to sheet segment base table 210 read the audio, video data of preview film to initial address 21N again.
Each section program can only have a kind of video data of single resolution in this DVD technology, that is media play system can't be handled two kinds of video datas that resolution is different simultaneously, so when making menu preview film, after need be labelled to the preview film earlier and become new film in the background pages (background page), carry out the film compression again, be stored to the DVD discs then.Yet the data quantity after the compression is because of comprising the background pages view data, so can occupy bigger storage area.
Among prior art, button and audio, video data mostly do not link (link), so can't random selection pre-looking.People's (United States Patent (USP) number 5963704) such as Mimura had disclosed a kind of menu system (as shown in Figure 3) 304 in 1998, and it is to be formed by a background dynamics image sequence 301, one sub-captions image 302 and 303 stack combinations of a highlight information.Wherein, comprised the image of all buttons in the sub-captions image, and highlight information has write down the information of each button, media play system can be known the position of each button by highlight information, and each button needs the order of execution under start-up mode.
When the user chooses a button, promptly enter preference pattern, media play system continues to play the background dynamics image sequence, find this information of choosing button by highlight information again, will belong to the image overlay of this button in the sub-captions image on the background dynamics image sequence according to key information at last.By foregoing description as can be known, this menu system only can be play the fixing background dynamics image sequence of a resolution, and preference pattern and start-up mode are only arranged, and can't change the film of playing under preference pattern, so can not reach the purpose of random selection pre-looking.
People's (United States Patent (USP) number 6266478) such as Yoshio had disclosed a kind of playing device in 1999, play sub-captions image, and this sub-captions image highlight picture (highlight display).(video object unit VOBU) is least unit with video object unit to be stored in data on the recording medium.Navigation bag among each VOBU (navigation pack) has write down highlight information, and this playing device, and is play understanding the information such as button, play position, color and reproduction time of the sub-captions image among the VOBU according to highlight information.The highlight information that sub-captions are only arranged in this highlight information not with the relevant information of video sequence (videosequence), does not just link between highlight information and the video sequence, is independent irrelevant.Therefore also can't select different buttons to change the video sequence of broadcast, can not reach the purpose of random selection pre-looking according to the user.
When viewing and admiring DVD or VCD film,, in the time of viewing and admiring again, can only the one section one section broadcast original film of jumping look for breakpoint at present if interruption is arranged, quite consuming time.If the function of random selection pre-looking is arranged, for a certain fragment of looking for film or want whole film is had the user of superficial impression, very large help will be arranged.
