sda 9415 - b13 preliminary data sheet introduction 13 micronas 1 introduction the sda 9415 is a new component of the micronas megavision ? ic set, which enables the system to reduce large area and line flickering of interlaced tv standards. the scan rate conversion to 100/120 hz interlaced or 50/60 hz progressive scan is motion vector based. for the 100/120 hz (50/60 hz) conversion the sda 9415 really calculates 100/120 hz (50/60 hz) fields with continuous motion phases to avoid double contour effects in the motion display. in the special case of movie sources, which have a non-continuous motion phase, the sda 9415 generates at the output an appropriate sequence with a continuous motion phase ( ? true motion ? ). due to the frame based signal processing, the noise reduction has been greatly improved. furthermore different motion detectors for luminance and chrominance have been implemented. for automatic controlling of the noise reduction parameters a noise measurement algorithm is included, which measures the noise level in the picture or in the blanking period. in addition a spatial noise reduction is implemented, which reduces the noise even in the case of motion. the sda 9415 has two input channels, which can be used for different features like picture-in-picture (maximum approximately 1/9 picture) and ? double-window/split- screen ? . the two input signals can be scaled horizontally and vertically with variable factors. panorama modes will be supported. besides that an algorithm for the detection of letter box pictures is included. the sda 9415 delivers the start and the end line of the active picture part of the input signal to an external c. the c calculates the zoom factors for displaying the active picture part on the full screen and sends this values back to the sda 9415. picture sharpness can be greatly improved by a lti (luminance transition improvement) or/and peaking and a cti (colour transition improvement) algorithm. the resolution of the output signals is 9 bit. the sda 9415 has analog output signals.

sda 9415 - b13 preliminary data sheet system description 23 micronas 5 system description 5.1 introduction the sda 9415 is the first single-chip micronas megavision ? feature box including scan rate conversion and the necessary field memories, a second input channel for split screen applications like picture-and-picture and digital-to-analog converters. the sda 9415 has three application modes: the src (scan rate conversion) mode, the ssc (split screen) mode and the mup (multi picture) mode. the two input channels of the sda 9415 are not equivalent. one input channel is always the so called ? master ? channel and one input channel is always the so called ? slave ? channel. both channels are combined of the output side of the sda 9415 in the ? mux ? block. the master channel is always the "synchronization" master of both channels. in the src mode the sda 9415 can be used as a high performance scan rate converter. scan rate conversion is done by a motion compensated algorithm known as micronas vdu (vector driven up conversion). in addition a high resolution frame based joint-line- free picture-and-picture (maximum approximately 1/9 picture) can be displayed. the figure below shows an example of the src mode. figure 4 principles of src mode
24 micronas sda 9415 - b13 preliminary data sheet system description for this usage the 6 mbit edram core is separated in two luminance fields and two chrominance fields (either 4:2:0 or 4:1:1) and a memory area for luminance and chrominance fields (4:1:1) [maximum circa 1/9 picture] for picture-in-picture applications. the vector based scan rate conversion is possible for the master channel only. for the ssc mode the 6 mbit edram core is split in two 3 mbit areas, which are able to contain a maximum of two luminance fields and two chrominance fields (either 4:2:0 or 4:1:1). the figure below shows different applications ( ? double window ? , ? zoom-in-zoom- out ? ). in this case only a simple scan rate conversion (e.g. field doubling for interlaced conversion: aabb) for both output channels is possible. figure 5 principles of ssc mode
sda 9415 - b13 preliminary data sheet system description 25 micronas the mup mode allows the combination of one life picture and a configuration of still pictures. the figure below shows an application. in this case only a simple scan rate conversion (e.g. field doubling for interlaced conversion: aabb or aaaa) is possible. figure 6 principles of mup mode the behaviour of the master and the slave channel does not differ in general. therefore for further description of the master and the slave channel the figures are also valid for both unless it is pointed out.

32 micronas sda 9415 - b13 preliminary data sheet system description the figure 9 shows the generation of the internal h- and v-syncs in case of full ccir 656 mode. the h656 sync is generated after the eav. the v656 and f656 signals change synchronously with the eav timing reference code. figure 9 explanation of 656 format the figure 10 explains the functionality of the syncenm/syncens signal. the sda 9415 needs the syncenm/syncens (synchronization enable) signal, which is used to gate the yinm/yins, uvinm/uvins as well as the hinm/hins and the vinm/vins signal. this is implemented for frontends which are working with 13.5 mhz and a large output delay time for yinm/yins, uvinm/uvins, hinm/hins and vinm/vins (e.g. micronas vpc32xx, output delay: 35 ns). for this application the half system clock clkm/clks (13.5 mhz) from the frontend should be provided at this pin. in case the frontend is working at 27.0 mhz with sync signals having delay times smaller than 25 ns, this input can be set to low level (syncenm/syncens= v ss ) (e.g. micronas sda 9206, output delay: 25 ns). thus the signals yinm/yins, uvinm/uvins, hinm/hins and vinm/vins are sampled with the clkm/clks system clock when the syncenm/ syncens input is low. the figure 10 shows the gated inputs signals yinmen, uvinmen, hinmen and vinmen. clk1 (27 mhz) u0 y0 v0 y1 u2 y3 yin ccir 656 interface sav eav 288 tclk1(pal) 276 tclk1(ntsc) eav 1728 tclk1(pal) 1716 tclk1(ntsc) eav x x eav x x sav x clk1 (27 mhz) yin x h656 eav v656 (e.g.) f656 (e.g.) 11111111 00000000 00000000 1fv1p 3 p 2 p 1 p 0 sav 11111111 00000000 00000000 1fv0p 3 p 2 p 1 p 0 f = 0 during field 1(a) f = 1 during field 2(b) v = 0 elsewhere v = 1 during field blanking msb lsb

76 micronas sda 9415 - b13 preliminary data sheet system description figure 31 explanation of memory management i the figure 32 shows a picture (boat, number 1), which is located with the left upper corner at the position (x1,y1). the picture will be compressed in vertical and horizontal direction and stored at the position (x2,y2). the vertical and horizontal compression mechanism of the input signal was explained before (compare "vertical and horizontal compression (vhcomm/vhcoms)" on page 36 ). this result could look like as showed in the picture number 2b. parts of the original boat are still visible. therefore in addition the i 2 c bus parameters lebordm/lebords, ribordm/ribords, upbordm/upbords and lwbordm/lwbords exist. these i 2 c bus parameters specify the amount of pixels at the left side and the right side and the amount of lines at the top and the bottom which has to be written in addition into the memory with coloured border values (i 2 c bus parameters yborderm, yborders, uborderm, uborders, vborderm, vborders). then the result could look like as showed in the picture number 2a (white border colour). the amount of pixels at the left side can be defined by the i 2 c bus parameters lebordm/lebords (amount of border pixels = 4 * lebordm/lebords) and the amount of pixels at the right side can be defined by the i 2 c bus parameter ribordm/ribords (amount of border pixels = 4 * ribordm/ ribords). the maximum amount of pixels, which can be written in addition, is 28 pixels on each side. the i 2 c bus parameters upbordm/s and lwbordm/s specify the amount of lines which has to be written in addition into the memory at the upper and lower edge of the picture with coloured border values. the maximum amount of lines, which can be written in addition, is 15 on each side. but there is a limitation that the sum of upbordm/upbords + lwbordm/lwbords should not exceed 20 (pal) lines. in horizontal direction as mentioned before only blocks (32 pixels) can be written into the memory. that means for instance if the lebordm parameter has a value bigger as zero and the 3 lsbs of iposxm parameter are zero (start position at a begin of a block), that the complete block on the left side of the block specified by iposxm will be filled with border colour. 32 * (iposxm)/8 32 0 64 iposym 0 block 1 2 04 8 32 28 24 4 * (iposxm modulo 8) 3 4 y/lines x/pixels
sda 9415 - b13 preliminary data sheet system description 77 micronas figure 32 explanation of memory management ii so the animation shown in the figure 32 can be done in the following way. the picture (boat) has at the beginning a defined size (defined by the i 2 c bus parameters applm1, alpfm1, inthm1, dezhm1, intvm1, dezvm1) and the left upper corner of the picture is located at the position (x1,y1) (defined by iposxm1, iposym1). specify the new picture size. set the corresponding i 2 c bus parameters (applm2, alpfm2, inthm2, dezhm2, intvm2, dezvm2) to get the new picture size. specify the new vertical and horizontal position (x2,y2) (defined by iposxm2, iposym2). specify in addition the amount of lines at the upper and lower edge, which has to be overwritten with border values. in addition the amount of pixels at the left and right edge, which has to be overwritten with border values (lwbordm, upbordm, lebordm, ribordm). send the new values to the i 2 c interface. remember that the reduction of the picture is limited in horizontal and vertical direction, if the border should be overwritten with border colour. the figure 33 shows in detail what happens by means of a horizontal bar, which is horizontally reduced. the width of the bar is 84 pixels (compare figure 33 ). the position x1, defined by iposx1 is for instance, iposxm1=00001100b=12 => x1 = 32 * 1 + 4 * 4 = 48 the i 2 c bus parameters lebordm and ribordm are both equal 0. the first block and the last block are filled up with border values (black colour - background value). the bar is compressed horizontally and the new width of the bar is 44 pixels. the new position defined by iposx2 after the reduction step may be iposxm2=00010001b=17=>x2 = 32 * 2 + 4 * 1 = 68. that means the actual picture size is reduced for 40 pixels, 20 pixels at the left side (left side = 68 - 48 = 20) and 20 pixels at the right side (right side = 132 - 20). therefore the upbordm lwbordm ribordm lebordm (x2,y2) (x1,y1) 1 2a x = 32 * iposxm/8 + 4 * (iposxm modulo 8) 2b
78 micronas sda 9415 - b13 preliminary data sheet system description i 2 c bus parameter lebordm has to be set to lebordm=5 (amount of pixels = 4*lebordm = 4*5 = 20), if the pixels remaining in the memory should be overwritten with border values. in addition the i 2 c bus parameter ribordm has to be set to ribordm=5 (amount of pixels = 4*ribordm = 4*5 = 20), if the pixels remaining in the memory should be overwritten with border values. the new position of the left edge is 68 and begin of the block is 64, thus the difference between the begin of the bar and the actual block is 68-64=4. that means that from the additional 20 pixels, which have to be written left of the bar, at least 16 pixels belong to the block which begins at the position 32. that means, that the complete block (begin at position 32) is filled up with border values. the same argumentation is valid for the right edge of the bar. figure 33 explanation of memory management iii repeating the procedure described above must be used for an animation as explained in figure 29 . 32 * (iposxm)/8 32 0 64 iposym 0 1 2 vhcomba3 32 * (iposxm)/8 32 0 64 iposym 0 1 2 reduction 48 96 68 iposx1 = 00001100=12 iposx2 = 00010001 x1= 32*1 + 4*4 = 48 lebord1 = 0 x2 = 32*2 + 4*1 = 68 lebord2 = 5 reduction 40 pixels lines pixels pixels lines 1 2 128 132 applm1 = 21 -> 8*21/2 = 84 pixel applm2 = 11 -> 8*11/2 = 44 pixel ribord1 = 0 ribord2 = 5 96 128 112

sda 9415 - b13 preliminary data sheet 87 micronas 5.7.3 switching from h-and-v-freerunning to h-and-v-locked mode in h-and-v-freerunning mode, generally, the phase of the generated synchronization line-scanning pattern has no correlation to the input line-scanning pattern. a hard switch from the h-and-v-freerunning mode to the h-and-v-locked mode therefore would cause visible synchronization artefacts. to avoid these problems the sda 9415 enlarges the line and the field lengths of the output sync signals hout and vout in a defined procedure to enable an invisible synchronization of the freerunning output to the input. for vertical synchronization the maximum synchronization time is 260 ms for interlaced and 520 ms for progressive display modes. horizontal synchronization is performed in a maximum time of 50 ms. to get the best performance it is recommended to change at first the vertical and after the mentioned delay times the horizontal mode from free running to locked. 5.7.4 operation mode generator the vout generator determines the vout signal. for proper operation of the vout generator information about the line-scanning pattern sequence is necessary. the i 2 c bus parameters stopmom (static operation mode master), stopmos (static operation mode slave) and the i 2 c bus parameter adopmom (adaptive operation mode master) define the line-scanning pattern sequence and the scan rate conversion algorithms.

sda 9415 - b13 preliminary data sheet 101 micronas the figure 42 shows the block diagram of the motion estimation and motion compensation block. the field information is read line-wise from the internal field store and written to a line-to-block converter. the motion estimation and the motion compensation block read the field information in parallel block wise from the line-to-block converter. the cache in front of the blocks enables a random access of the field information. the result of the motion estimation is stored in the vector memory, which is also used as a vector field memory for the 3-d recursive block matching algorithm. at that time only vector information of block resolution is available. the post processing block computes a vector information of pixel resolution basis, which can be used from the motion compensation block for the up conversion process. finally the results of the motion compensation block are written to the block-to-line converter block. figure 42 block diagram of motion estimation and compensation the figure 43 illustrates a more detailed block diagram of the motion estimation block. the motion estimation block is separated in two branches. the left one is only responsible for still area detection and the right one for all kind of areas. the additional left branch can be switched off or on by the i 2 c bus parameter menullfunon (i 2 c bus parameter 4bh). different preprocessing blocks are located in both branches due to the different tasks of the branches. after preprocessing of the input data the main computation, the block matching, is executed. for the right branch, the motion estimator applies two concurrent recursive block matchers, that individually check three candidate vectors with different convergence directions. among the three candidates there is one spatial prediction vector taken from a previously processed block and a temporal prediction vector. the temporal prediction has the characteristic feature that its position is shifted with respect to the block currently processed in the opposite direction compared to the spatial prediction. the figure 44 field store edram cache motion estimation motion compensation vector post processing vector memory line to block converter block to line converter me03 bvmcon mesmoothon me-i2c bus parameter filsel vecdison cache bvmres
