Read supplementary from CD 101 or local portion memory 102 again.In the present embodiment, from realizing the viewpoint of picture-in-picture function, read the subsidiary supplementary of second image information from local portion memory 102.The supplementary of reading is sent to supplementary analysis unit 109.In supplementary analysis unit 109, carry out the parsing of supplementary, extract the effective coverage information of second image out and use time information.The effective coverage information of extracting out is sent to control part 111, and the application time information that will extract out is again delivered to comparing section 112.
In comparing section 112, carry out above-mentioned application time information and, export comparative result to control part 111 from the benchmark comparison constantly that reference time counter 110 is imported.
In control part 111, in the moment of the comparative result demonstration of importing from comparing section 112 " unanimity ", to use from the effective coverage information of supplementary analysis unit 109 inputs, the indication that relevant second image is shown conveys to display image formation portion 108.
In display image formation portion 108, utilize first image information, second image information and above-mentioned graphical information, synthetic output image picture.At this moment, according to from controlling 111 instruction contents that send, carry out the synthetic of second image information.
Now, explain the action of display image formation portion 108 a little with reference to Fig. 2.
Fig. 2 is the schematic diagram of an example of the structure of expression display image formation portion 108.201 is first video plane; 202 is second video plane; 203 is present graphical plane (presentation graphics plane); 204 is interactive graphics plane (interactive graphicsplane); 205,206,208,209,211,212 is multiplier; 207,210,213 is adder.With the corresponding part of Fig. 1 with identical symbolic representation.
In the present embodiment, the effective coverage for being stored in second image information in second video plane 202 that becomes feature limits this point and this effective coverage information is input to additional multipliers 205 and 206 this point.These effective coverages limit basic identical with existing structure with the inapplicable situation of effective coverage information.In order to represent the characteristic point in the present embodiment, use Fig. 3 at first in the lump, the basic display mode of the picture-in-picture shown in the above-mentioned existing example is described.
Be stored in first video plane 201 from first image information of Video Decoder 1 (104) output.In addition, second image information from Video Decoder 2 (105) outputs is stored in second video plane 202.As shown in Figure 3, represent that first video plane 201 and second video plane 202 are with respect to the HD size, second image information has the resolution as the HD size of image, but the effective coverage is the SD size all, and only is pasted with the situation of image on the part of second video plane 202.
Secondly, the situation of the image of HD size as second image information used in explanation simply with reference to Fig. 4.Shown in second video plane 202 of Fig. 4, second image information is common HD size.The output of first video plane and second video plane is estimated with opacity α 1 on the Zone Full of HD size, exports display image 401 at last.Decision about α 1 is: brightness or aberration composition are that the pixel of setting following (or more than) is all carried out the processing of α 1=0.Because the determining method of the opacity of this pixel composition, be general (for example chroma key etc.) as the method for image construction, omit its detailed description.
Like this, in second image information, under the situation of the image of use HD size, the decoding capability of HD size must be arranged in Video Decoder 2 (105), such as described above, consider with Video Decoder 1 (104) to cooperate that treating capacity is very many.
In the present embodiment, shown in Fig. 5 A, 5B, limit the effective coverage of second image information.Shown in Fig. 5 A, the content author utilizes only demonstration to make image encoding as the mode in the zone of second image information necessity, shown in Fig. 5 B, generates the area information of effective coverage altogether.For example, be limited in below 1/6 of HD size by the aggregate value with the effective coverage, even encode with the HD size, the effective value of coding is the SD size.
Particularly, the situation that makes second encoding image information with the MPEG2 visual form is described simply.As shown in Figure 6, take out the time of each frame of image and the relevant information in space with the MPEG2 video mode, difference value is encoded.Obtain the stipulate unit (macro block) of unit for being made of brightness and aberration of relevant information, also can make the interior inactive area of 1 frame is that skipped macroblocks (skipmacro block) (encoding amount minimum) is encoded.
But, even still reproduce as second image information, the essential determining method of opacity in early stage that utilizes is correctly synthetic because inactive area is not qualification, therefore, can with in the input of the effective coverage information shown in the above-mentioned Fig. 5 B multiplier 205 and 206 as the decisive factor of the opacity α 1 of Fig. 2.In multiplier 205 and 206, according to above-mentioned effective coverage information, get α 1=0 in (being inactive area) beyond the effective coverage, show first image information always.In addition, in the effective coverage, can use above-mentioned opacity determining method (chroma key etc.) in addition.
As described above, according to present embodiment, with second encoding image information, make that the effective coverage is below the regulation ratio of HD size as the HD size, during reproduction, owing to also use effective coverage information, can carry out the synthetic of first image information and second image information, therefore in carrying out picture-in-picture function, the treating capacity of the decoder that can reduce can realize that desirable image is synthetic.
In addition, in the present embodiment, basically before the coding result that the inactive area of considering second image information has been described changes a little, do not utilize effective coverage information according to this state, the opacity that unconditionally makes inactive area is 0 situation, if but for example under uniform state, under the situation about inactive area can be encoded, the ratio of effective coverage during by the restriction coding, Zone Full in decoded second image information is used above-mentioned opacity determining method (chroma key etc.), also can obtain desirable effect.In addition, in the present embodiment, illustrated and used the MPEG2 visual form, the situation that second image is encoded, but if in the effective coverage, emphasis ground allocated code, the mode of encoding then is not limited to its form.
[embodiment 2]
Secondly, the second embodiment of the present invention is described.
Because the block diagram of the transcriber of present embodiment is identical with Fig. 1, omits detailed explanation.With the difference of first embodiment is that second image information is the SD size, and is littler than the size on the picture of first image information.As described in first embodiment, if second image information is the SD size, then the situation with the HD size compares, and only just can reduce the treating capacity of Video Decoder like this.But under the situation of SD size, the use zone of second video plane 202 is restricted, making the different place of a plurality of sprites, can not synthesize etc.
In the present embodiment, shown in Fig. 7 A, second image information is divided into for example 4 parts, in each zone, disposes different personage etc.,, can be used as the SD size and encode as image.And for example shown in Fig. 7 B, in each zone of cutting apart, finally be created in the demonstration of first image information, dispose all intelligible positional information in any position and use timing, this information is provided.Promptly in the supplementary analysis unit 109 of Fig. 1, extract the positional information of above-mentioned cut zone out and use timing, these information are imported display image formation portion 108 by control part 111 from supplementary.
Fig. 8 is an example of the formation of the display image formation portion 108 of this situation of expression.The part identical with Fig. 2 is with identical symbolic representation, detailed.Be input to the position correction portion 801 from the sticking position information of the cut zone of control part 111 output.In position correction portion 801, after carrying out position correction, the data of the pixel unit read from second video plane 202 are used opacity, and carry out add operation according to above-mentioned positional information.
The object lesson of this situation of expression in Fig. 9.Second image information utilizes the SD size to encode, and is 4 parts with Region Segmentation.On video plane 202, second image information is the SD size still, but utilizes position correction portion 801, to area unit correction display position, finally can obtain display image output in any local mode that shows desirable zonule as 901 as picture-in-picture function.
As above such, use present embodiment, second image information as the SD size, is limited treating capacity, and as picture-in-picture function, can show sprite on a plurality of positions.
In the present embodiment, constitute position correction portion 801 is configured on the back segment of second video plane 202, but, also can obtain same effect the leading portion that position correction portion is configured in second video plane 202.In this case, second image information of decoding is stored on second video plane 202 through position correction.
[embodiment 3]
