This embodiment makes multimedia messages as one man automatically to issue on different channel terminal based on terminal by all kinds of means from adaptation technique, and this embodiment can also continue to optimize the database comprising display parameters, thus contribute to the efficiency improving multimedia messages layout and issue further.
Particularly, in a step 102, the resolution of the screen gross space that display-object function and the multimedia messages set up take and terminal is relevant, wherein, the screen gross space that multimedia messages takies refers to the pixel count of multimedia messages in the terminal receiving this information shared by reality, the resolution of terminal comprises the resolution L on the length direction of terminal and the resolution H in short transverse, and in an example, this display-object function can show utilance Pc with real space and be expressed as:
Wherein, the gross space of terminal interface is the product of resolution L and resolution H, for the ease of calculating, the total number of word that terminal interface can show can be calculated by the pixel number shared in different font size situation according to character each in text, the gross space that text takies is text total number of word, the gross space shared by picture by picture amount to text after suitable text number of words.
In the present invention, the channel terminal of receiving multimedia information can include but not limited to mobile phone, iPAD, PC, IPTV.When channel terminal is mobile phone, its screen resolution roughly can be divided into QVGA (QuarterVGA), HVGA (Half-sizeVGA), VGA (VideoGraphicsArray), WVGA (WideVGA) four kinds, particularly, the resolution of QVGA is 240 × 320 pixels, it is the resolution levels that smart mobile phone is the most frequently used instantly, the resolution of HVGA is 480 × 320 pixels, the resolution of VGA is 640 × 480 pixels, and the resolution of WVGA is 800 × 480 pixels.When channel terminal is iPAD, its resolution can be 800 × 480 pixels and 854 × 480 pixels two kinds.When channel terminal is IPTV, its resolution can be 720 × 576 pixels (pal mode) or 720 × 480 pixels (TSC-system formula), high definition correspondence 1280 × 720 line by line (namely, 720p), 1280 × 720 interlacing (that is, 720i), 1920 × 1080 line by line (namely, 1080p) or 1920 × 1080 interlacing (that is, 1080i).
In addition, the total capacity of multimedia messages comprises the total number of characters and total picture number that comprise in text, that is, be this two parts capacity sum.
Suppose that multimedia messages to be released is only text (its total number of characters is 285), the terminal receiving this multimedia messages is mobile phone terminal, its resolution is QVGA, then now setly for mobile phone terminal institute input parameter be: 240 × 320 pixels, 285.
In step S104, display parameters can include but not limited to text formatting and picture format, wherein, text formatting can include but not limited to size and the spacing of text font, picture format can include but not limited to the size of picture and position (that is, the relation between picture and text, such as, word and picture around mode), the parameter list of following form can be stored in a database:
Table 1
If the resolution of channel terminal is 240 × 320 pixels, the total number of word of the multimedia messages issued is 204, and do not comprise pictorial information, then directly can select the display parameters that display effect meets the demands from table 1: test font size is No. 11 (each character of No. 11 words comprises 14*14 pixel), the spacing of character is 0.05 set width, and line space is 0.5 set width.
In step s 106, constraints can include but not limited to that the length to height ratio of character is constant and (be out of shape to prevent font, the general size only adjusting word, do not adjust the length to height ratio of word), the resize ratio of picture size and length to height ratio is no more than setting threshold (such as, picture size is between 90% and 110% of original image, when adjusting length and height respectively, each self-adjusting ratio is all between 95% and 105%) and position relationship between character and picture is (such as, character is around picture, and character is not around picture).
Suppose that the resolution of channel terminal is 240 × 320 pixels, total number of characters of the multimedia messages issued is 285, and do not comprise picture in multimedia messages, then can not find directly available display parameters from the database of table 1, now, search from the database shown in table 1 with multimedia messages total capacity (such as, 285 characters) immediate display parameters, in the unequal situation of total capacity, be preferentially immediately search principle with number of characters, search parameter combinations immediate with total number of characters in a database, immediate display parameters can be found, such as, " 240 × 320, 204+0 " " line space of word space+0.5 set width of No. 11+0.05 set widths " in situation, using the immediate display parameters the selected initial value as iterative algorithm.
Particularly, available display parameters can be determined by following step: utilize immediate display parameters and display-object function to calculate the real space display utilance of the terminal of receiving multimedia information, space according to the real space display utilance calculated and setting shows the adjustment trend of the relation determination display parameters between utilance threshold value and adjusts step-length, because space display utilance threshold value has certain interval range, so when the real space display utilance calculated is in this interval, directly can use selected immediate display parameters, when the real space display utilance calculated is positioned at the left side in this interval (, actual value is much smaller than threshold value), the size of font and/or picture can be increased, when the real space display utilance calculated is positioned at the right side in this interval (, actual value is much larger than threshold value), the size of font and/or picture can be reduced, and (can be adjustment step-length with least unit according to adjustment trend and adjustment step-length, such as, font increases or reduces No. 1, picture ratio increases or reduces 1%) adjust immediate display parameters, until the requirement of real space display utilance meeting spatial display utilance threshold interval.Can hypothesis space display utilance threshold value be 85%, interval range be [83%, 87%], that is, think when the actual displayed utilance calculated is less than or equal to 2% with the absolute value of the difference of display utilance threshold value and meet threshold interval requirement, then iteration terminates.
First, utilize formula (1) calculate font size be No. 11, under word spacing be 0.05 set width and line space is 0.5 set width situation, space display rate shared by 285 character reality, the terminal being 240 × 320 due to resolution can show at most 240 No. 11 Song typeface characters, so can calculate Pc is 118%, as can be seen here, itself and 85% the absolute value of difference much larger than 2%, and on the right side of threshold interval, therefore font size and/or spacing (such as, word space, line space) is needed to turn down.Such as, first font size can be turned down, become No. 9 (each character of No. 9 words comprises 12*12 pixel) from No. 11, do not adjust spacing, at this moment font size is calculated again for space display rate when No. 9 shared by these 285 character reality, the terminal being 240 × 320 due to resolution can show at most 342 No. 9 Song typeface characters, so can calculate now Pc is 83.3%, itself and 85% difference be less than 2%, therefore, iteration terminates, now obtaining available display parameters is " line space of word space+0.5 set width of No. 9+0.05 set widths ", in order to improve the efficiency for issuing of subsequent multimedia information, can these display parameters be updated in database, as described in Table 2:
Table 2
Suppose that the resolution of channel terminal is 240 × 320 pixels again, the total number of word of the multimedia messages issued is 155, and do not comprise picture in multimedia messages, then can not find directly available display parameters from the database of table 2, now, search from the database shown in table 2 with multimedia messages total capacity (such as, 155 characters) immediate display parameters, can find immediate display parameters is " 240 × 320, 204+0 " " line space of word space+0.5 set width of No. 11+0.05 set widths " in situation, using the immediate display parameters the selected initial value as iterative algorithm.
First, utilizing formula (1) to calculate in font size is No. 11, word spacing is 0.05 set width and line space is in 0.5 set width situation, space display rate shared by 155 character reality, the terminal being 240 × 320 due to resolution can show at most 240 No. 11 Song typeface characters, so Pc is now 65%, can find out itself and 85% the absolute value of difference be greater than 2%, and in the left side of threshold region, visible, font size and/or spacing is needed to tune up, first font size can be tuned up, become No. 12 (each character of No. 12 words comprises 16*16 pixel) from No. 11, do not adjust spacing, at this moment font size is calculated again for space display rate when No. 12 shared by 155 character reality, the terminal being 240 × 320 due to resolution can show at most 182 No. 12 Song typeface characters, so can calculate now Pc is 85.2%, itself and 85% difference be less than 2%, therefore, iteration terminates, now obtaining available display parameters is " line space of word space+0.5 set width of No. 12+0.05 set widths ", in order to improve the efficiency for issuing of subsequent multimedia information, can these display parameters be updated in database, as described in Table 3:
Table 3
Based on the processing mode same with text, when not only having comprised text but also comprised picture in multimedia messages, the size of font in preferential adjustment text, when still not meeting above-mentioned threshold requirement after test font size adjustment, can adjust the overall ratio of picture again, or the length ratio of independent adjustment picture consequently finally drops in threshold interval with height ratio.
When adjusting picture size, every width picture equal proportion can be amounted to into number of characters, if picture adopts non-legible around mode, then line number (general every width picture takies 5 row) shared by picture and number of characters that often row can show can calculate the suitable number of characters of this width figure; If adopt word around mode, the line number shared by the length of every width figure and high ratio, picture calculates the suitable number of characters of every width figure, thus finally calculates the space display rate shared by multimedia messages reality comprising text and picture.
