Then with the position lateral excursion of image buffer 2; The unit number of skew can change, and is offset fewly, and stereoeffect is not obvious, is offset too greatly, two separation of images, can not produce stereoeffect yet.When watching, can utilize above congener macyscope, the right and left eyes eyeball is only seen respectively and the colour of lens uniform images, and filtered the image of complementary colors, thereby produce stereoeffect, the distance of skew is as the criterion can produce stereoeffect.
Image with image buffer 2 merges to image buffer 1 at last, is integrated into a stereographic map picture frame.
The above-mentioned processing of process just can define to become and play after three-dimensional fragment is treated to stereoeffect.
II, atomizing: will produce atomizing effect if in system's navigation information, defined certain fragment, when playing, will call corresponding program according to this definition, packed data to this fragment is handled, make this fragment produce atomizing effect, produce atomizing effect, as long as replace original pixel in the picture with pixel the interval order line by line of white by certain.
III, transition: if the conversion that has defined in system's navigation information between certain two fragment will realize with transitions, when playing, will call corresponding program according to this definition, packed data to respective segments is handled, that is: regulate the hardware brightness register, the picture brightness that makes current fragment is from normally deepening gradually, and the brightness of the picture of next fragment is from secretly being gradually varied to normal process.
IV, tone are regulated: if defined in system's navigation information the tone of certain fragment is regulated, when playing, will be called corresponding program according to this definition, the packed data of this fragment is handled:
At first the tone mode with the own appointment of user is stored in R_user, and G_user is in the B_user register;
Its subsystem is according to the RGB pattern of user's appointment, increases or reduce the storing value of the RGB of system in specific ratio, that is: with the R_user of user's appointment, and G_user, the value addition of the value of B_user and the RGB of system register or subtract each other.Value with amended RGB register is saved in the system at last, so that reach the effect that changes tone.
More than the process of several variations just illustrate, further processing to image or sound has been a proven technique, simultaneously can be in conjunction with the variation in each program different fragments reproduction time, space, when playing, can produce a lot of combinations, thus when playing, can produce one can with the diverse works of the effect of original works.
If there is not any program disk of D11 navigation information, its player method is:
1) reads program file, carry out catalogue and file identification;
2) judge whether and have decoding file layout coupling;

If other types find the root directory address information by filesystem information, further find the fileinfo under the root directory, judge program format according to file and catalogue, if any: VIDEO_TS and AUDIO_TS directory name, then utilize the DVD decodes and plays; If any the file of .MP3, then utilize the MP3 decoding music file to play under the catalogue; If the file of .MPG is arranged equally, then utilizes MPEG1 decoded picture file to play; If the file of .AVI is arranged, then utilize MPEG4 decoded picture file to play; If the file of .JPG is arranged, then utilize the JPEG picture file to play;
If there is not suitable identification document, whether have self-defined program decoding storehouse, if having, then decode by its definition if can search automatically; If do not have, scan-data bag then, general program file is made up of fixed length/random length packet, scanning by packet header, show that as 00 00 01 Bx this file type is the MPEG2 type, " RIFF " shows that this file type is MPEG1, MPEG4 or other type of codings (determining the decoding sign) by FORCC CODE, programme information according to system's bag is described, can determine resolution and decode rate, voice codec information and stack picture and text all may be included in other packets or the JUNK piece, can determine other supplementarys by scanning 1000 above packets or JUNK piece, determine demoder, it is play by such mode.
If the user wishes self-defined minute fragment and generates special efficacy, also can before decodes and plays, carry out segmentation generation program navigating information by the packed data to this program, again fragment is carried out the preparation of system's navigation information.
In above player method, can be when playing the program of a plurality of different systems, the process that a program switches can be set in playing program, promptly just set one and play priority list, in described priority list, defined program, the precedence of playing for different compression methods at playing program, thereby when one of broadcast has the D11 dish of the multi-system program, can judge automatically and switch the order of playing, particular flow sheet is described as follows as shown in Figure 6:
