Embodiment
Provide description below, with the exemplary embodiment of the present invention that helps complete understanding to limit by claim and equivalent thereof with reference to accompanying drawing.This description comprises various specific detail help understanding, but should to be considered to only be exemplary to these details.Therefore, those skilled in the art will appreciate that under situation about not departing from the scope of the present invention with spirit, can carry out various changes and modification embodiment described here.In addition, for clear and simple and clear, the description of known function and structure will be omitted.
Fig. 1 is the method for adding sprite before video record according to the first embodiment of the present invention.
With reference to Fig. 1, below will be described in add sprite before the video record method.At first, determine sprite at step S101.Sprite can derive from the built-in template of video camera, video camera inputting interface, data wire download, network download, but the invention is not restricted to this, also can use the sprite source of other types.The type of sprite for example can comprise memorandum text, photo frame etc., therefore, determines that sprite just edits the memorandum text, and operations such as photo frame color are set.In Fig. 1, text " travel in Tibet " and date " 15/06/2007 " in sprite, have been added.
According to the DVD-Video standard, sprite can only be by following four types of points (promptly, four types pixel) constitute: background (background), pattern (pattern), emphasis-1 (emphasizing-1), emphasis-2 (emphasizing-2), be furnished with 00,01,10,11 binary data value separately.Therefore, a sprite comprises four kinds of colors at most simultaneously, and wherein, color is any one in the 16 tone colour tables.In addition, every type of point all has the transparency attribute, i.e. 16 grades contrast, and transparency is a kind of in the 16 rank transparencies, for example, if value is 0, then expression is transparent fully, if its value is 15, then expression opaque entirely (Fullopacity).Under normal conditions, the some color of background type is not limit, but transparency should be bright for full impregnated.As can be seen from Figure 1, sprite has adopted the bright point of white, the full impregnated of background type as a setting, and adopts the red complete opaque point of pattern type to constitute the memorandum text.
Next, sprite is converted to sub-picture unit SPU_1 (S102).For example, can use the coding method of RLE (run length encoding) that sprite is converted to sub-picture unit.
At this moment, use video camera to begin the DVD video record.In general, the DVD video camera can generate MPEG-2 video flowing (S103) by the video of recording being carried out the MPEG-2 coding.Selectively, can the video of recording be mixed effect (S104) afterwards with sprite by OSD (showing) function preview with screen.In Fig. 2, can see in the preview this moment design sketch, memorandum text " travel in Tibet " and date " 15/06/2007 " have appearred having added on video pictures.
At step S105, the video that SPU_1 is applied to record is just multiplexing with the MPEG-2 video flowing of recording with SPU_1, thus generate the PS stream (program stream) that comprises sprite.Because add sprite in the video record incipient stage, in replayed section, sprite will run through the whole video fragment like this.
When recording end, replenish a VOBU (video object unit) at the PS of multiplexing generation stream tail, in this VOBU, comprise the sub-picture unit SPU_2 (S106) that empties the sprite control command.In general, one section memorandum (perhaps photo frame) only is used for one section continuous videos (that is, from beginning to be recorded to one section continuous videos recording between finishing to record), therefore, need close the sprite demonstration automatically when this section video finishes.Can realize this function by adding aforesaid VOBU.In addition, VOBU also comprises a MPEG-2 video I frame according to the DVD-Video normalized definition, last picture when recording as end.
Then, will constitute a complete cell unit (cell is that dvd goes up minimum video unit), and the 16 tone colour table information that the sprite overall situation is used will be recorded in the IFO file with termination disc (S107) through the PS stream of above-mentioned processing.The IFO file is that the control vob file is play, and can find the relevant control information such as data of how and when playing in the vob file in this file.In the method according to the first embodiment of the present invention, the palette information of sprite is write in the IFO file, thereby can control the formation color of sprite.
With reference to Fig. 2 according to a second embodiment of the present invention the method for adding sprite behind video record is described below.
At first, use the DVD video camera to begin the DVD video record.After video record finishes, replenish a VOBU at PS stream tail, this VOBU comprises the SPU_2 that empties the sprite control command.The DVD video of recording (this video comprises above-mentioned VOBU, promptly comprises the SPU_2 that empties the sprite control command) is constituted a complete cell unit, i.e. a video cell.Next, determine sprite, sprite is converted to SPU_1.As shown in Figure 2, the sprite of determining in the second embodiment of the present invention is basically the same as those in the first embodiment, and, has added memorandum text " travel in Tibet " and date " 15/06/2007 " that is.More than therefore the class of operation among the operation and first embodiment seemingly, is not described in detail above step.
Next, generate new cell unit, i.e. a sprite cell with the sprite of determining.In the present embodiment, described sprite cell comprises a VOBU, and this VOBU comprises above-mentioned sprite SPU_1 and the MPEG-2 video I frame according to the DVD-Video normalized definition, herein, and first frame when the I frame begins to record for video cell.
Then, sprite cell is recorded the back of video cell.Because DVD-R/-RW video disc WriteMode restriction, cell can only journal, therefore sprite cell can only write the zone that is right after video cell on the disc (this is that physical write mode by video disc limits), and sprite cell has identical VOB ID number with video cell.Identical with first embodiment, can use OSD to mix to come preview to add the DVD video pictures of sprite.
With program (program, playing sequence information PG) (PGC_PGMAP, C_PBI) be set at sprite cell-video cell, and be recorded in the IFO file.
Because the playing sequence of DVD-Video video is by program chain described in the IFO file (Program Chain) and program tissue, the physical record order of video unit on disc do not place one's entire reliance upon, therefore, when a PGC comprises one or more PG, when played in order, PG always plays in order successively.PG has write down the information (Entry Cell Number) that enters cell, when playing PG, always begins to play from Entry Cell, plays the next cell (Cell Number++) of this cell then.
The address information recording of cell is in C_PBIT (Cell Play Back Information Table), therefore, as shown in Figure 2, allow the physical address of previous Cell (Cell i) record sprite cell in the IFO file, and allow the physical address of a back Cell (Cell i+1) recording of video cell, simultaneously, the Entry Cell Number that other comprises the PG of Cell i and Cell i+1 is i, like this, when playing this PG, will navigate to sprite cell earlier, and broadcast sprite cell, and then navigate to video cell then, and beginning displaying video cell, so can observe the video that is added with sprite.
At last, palette information is recorded in the IFO file, and the termination disc.Identical with first embodiment, palette information is 16 tone colour table information of an overall situation.
It is the method that a DVD video cell (that is DVD video segment) adds a sprite that Fig. 2 shows.Those skilled in the art should be easy to expect, can also use according to the method for second embodiment of the invention and before DVD disc termination, add sprite as the video segment that arbitrary number has been recorded, wherein, the pattern of sprite and type can change according to each video segment.For example, add memorandum text inequality for each fragment, perhaps add the photo frame of different outward appearances, to play the effect that increases different sprites according to the DVD video content according to the content of fragment.
Specifically, the DVD video segment of having recorded for a plurality of numbers method of adding sprite mainly comprises: adopt the method for second embodiment of the invention produce a plurality of video cell and with the corresponding a plurality of sprite cell of described a plurality of video cell; The playing sequence of each sprite cell is set to before its corresponding DVD video cell, and playing sequence is recorded the IFO file to upgrade.Adopt above-mentioned method, can after having recorded a plurality of DVD video segments, unify to have improved treatment effeciency, and also can make overall arrangements video and sprite for it adds sprite.
Fig. 3 shows the design sketch of the DVD video that has added memorandum text and photo frame special efficacy respectively.Shown in the left side of Fig. 3 be the DVD video effect that has added the memorandum text " travel in Tibet " and the memorandum effect on date " 15/06/2007 ", shown in the right side is the DVD video effect that has added the photo frame effect.Yet addible effect is not limited to the example shown in Fig. 3.Any available effect sprite can add the DVD video to by the method for the embodiment of the invention before the termination disc, should be appreciated that these are included within the scope of the present invention.
By the method for various embodiments of the present invention, on-the-spot for the DVD video adds sprite before DVD disc termination after can or recording before the DVD video record, thus simplified the treatment step of DVD video, saved time and cost, be convenient to user's operation.
Though illustrated and described some embodiment of the present invention, but it should be appreciated by those skilled in the art that, under the situation of principle of the present invention that does not break away from the claim qualification and spirit, can make various changes, scope of the present invention limits in claim and equivalent thereof.
