functional description stw8009/stw8019 10/65 4 functional description 4.1 general stw80x9 operates either in master mode where it supplies all sync signal or in slave mode. the digital input is an 8-bit bus carrying y, cb and cr at 13.5 mhz. input samples are latched in on the rising edge of the clock input signal. stw80x9 is able to encode interlaced (in all standards) and non interlaced (in pal and ntsc) video. stw80x9 outputs interlaced or non-interlaced video in pal-b,d,g,h,i,pal-n,pal-m or ntsc-m standards (?ntsc-4.43? is also possible). the burst sequences are internally generated, subcarrier generation being performed numerically with the 27 mhz as reference. 4-frame bursts are generated for pal or 2-frame bursts for ntsc. rise and fall times of synchronization tips and burst envelope are internally controlled according to the relevant itu_r and smpte recommendations. 4.2 master & slave modes in master mode, stw80x9 supplies hsync and odd/even sync signals (with independently programmable polarities) to drive other blocks. stw80x9 starts encoding and counting clock cycles as soon as the master mode has been loaded into the control register (reg 0). configuration bits ?syncout_ad[1:0]? (reg 4) allow to shift the relative position of the sync signals by up to 3 clock cycles to cope with any ycbcr phasing. in slave modes, several modes are available, odd/even+hsync based, vsync+hsync based, odd/even-only based, vsync-only based or sync-in-data based. 4.3 auto test mode an auto test mode is available, which causes stw80x9 to produce a color bar pattern, in the appropriate standard, independently from the video input. 4.4 input demultiplexor the incoming ycbcr 4:2:2 data are demultiplexed into chroma information stream, a ?blue- difference? and a ?red-difference?, and a luma information stream. incoming data bits are treated as blue, red or luma samples according to their relative position with respect to the sync signals. brightness, saturation and contrast are then performed on demultiplexed data. the itu-r601 recommendation defines the black luma level as y=16dec and the maximum white luma level as y=235dec. similarly it defines 255 quantification levels for the color difference components (cr, cb) centered around 128. accordingly, incoming ycbcr samples can be saturated. in this case stw80x9 provides a saturation limitation feature to avoid having heavily saturated signal before digital to analog conversion and to avoid generating a distorted signal at stw80x9 cvbs or y/c outputs.
stw8009/stw8019 functional description 11/65 4.5 video timing the denc outputs video in pal-b,d,g,h,i, pal-n, pal-m or ntsc-j, m standards (?ntsc- 4.43? is also possible). the burst sequences are internally generated, subcarrier generation being performed numerically with pix_clk as reference. 4-frame bursts are generated for pal or 2-frame bursts for ntsc. rise and fall times of synchronization tips and burst envelope are internally controlled according to the relevant itu-r and smpte recommendations. figure 5 , 6 , 7 and 8 depict typical vbi waveforms. it is possible to allow encoding of incoming ycrcb data on those lines of the vbi that do not bear line sync pulses or pre/post-equalization pulses ( figure 5 , 6 , 7 and 8 ). this mode of operation is referred to as ?partial blanking? and is the default set-up. it allows to keep in the encoded waveform any vbi data present in digitized form in the incoming ycrcb stream. alternatively, the complete vbi may be fully blanked, so no incoming ycrcb data encoded on these lines. the ?complete? vbi comprises of the following lines: ? for 525/60 systems (smpte line numbering convention): lines 1 to 19 and second half of line 263 to line 282 ? for 625/50 systems (ccir line numbering convention): second half of line 623 to line 22 and lines 311 to 335 the ?partial? vbi consists of: ? for 525/60 systems (smpte line numbering convention): lines 1 to 9 and second half of line 263 to line 272 ? for 625/50 systems (ccir line numbering convention): second half of line 623 to line 5 and lines 311 to 318 full or partial blanking is controlled by configuration bit ? blkli in configuration register1?. note: line 282 in 525/60/smpte systems is either fully blanked or fully active. line 23 in 625/60/ccir systems is always fully active. in an itu-r656-compliant digital tv line, the active portion of the digital line is the portion included between the sav (start of active video) and eav (end of active video) words. however, this digital active line starts somewhat earlier and may end slightly later than the active line usually defined by analog standards. the denc permits two approaches: encodes the full digital line (720 pixels / 1440 clock cycles). in this case, the output waveform will reflect the full ycrcb stream included between sav and eav. drops some ycrcb samples at the extremities of the digital line so that the encoded analog line fits within the ?analog? itu-r/smpte specifications. selection between these two modes of operation is performed with bit ?aline? in configuration register 4. in all cases, the transitions between horizontal blanking and active video are shaped to avoid too steep edges within the active video. figure 11 on page 15 gives timings concerning the horizontal blanking interval and the active video interval.

stw8009/stw8019 functional description 15/65 4.6 sub-carrier generation a direct digital frequency synthesizer (ddfs) generates the required color sub-carrier frequency using a 24-bit phase accumulator. sub-carrier frequency is programmable with a 1.6 hz step. 4.7 luminance encoding the luminance that is added to the chrominance to create the composite cvbs signal can be trap-filtered at 3.58 mhz (ntsc) or 4.43 mhz (pal). this supports application oriented towards low-end tv sets which are subject to cross-color. a 7.5 ire pedestal can be programmed if needed with all standards. this allows in particular to encode argentinian and non-argentinian pal-n, or japanese ntsc. a programmable delay can be inserted on the luminance path to offset any chroma/luma delay introduced by off-chip filtering. stw80x9 output signals are if modulated in ntsc m standard so that a sound notch filter is required. the notch filter which is on the luma path is defined by a set of coefficients and is implemented in the stw80x9 as default values. the set is also programmable. table 2. ntsc and pal timings ntsc-m pal-bdghi pal-n pal-m a (1) 1. these are typical values. actual values will depend on the static offset programmed for subcarrier generation 5.38 s (even lines) 5.52 s (odd lines) 5.54 s (a-type) 5.66 s (b-type) 5.54 s (a-type) 5.66 s (b-type) 5.73 s (a-type) 5.87 s (b-type) b1 1.56 s1.3 s1.3 s1.56 s b2 1.56 s1.52 s 1.52 s1.56 s c1 8.8 s9.6 s9.6 s8.8 s c2 9.41 s10.48 s10.48 s9.41 s d 9 cycles of 3.58mhz 10 cycles of 4.43mhz 9 cycles of 3.58mhz 9 cycles of 3.58mhz
