FUNCTIONAL DESCRIPTION Field rate up-conversion with line flicker reduction The line flicker reduction in conjunction with field rate up-conversion is performed by generating a 50 Hz interlace on the 100 Hz field rate display. Median filtering supplies the data for the interlaced output fields. DEFINITIONS Framel: l is the number of an input/output frame temporarily combinating an A and B field. Field n : x is the field raster where A means an odd field and B means an even field. Framel, k: l is the number of an output frame temporarily combinating an origin/interpolated A and B field; k indicates the origin input field with k = 1: odd input field and raster A k = 2: even input field and raster B within framel.

Progressive scan Progressive scan conversion produces a double number of lines per field on the output. The field frequency is not changed, while the line frequency is doubled. Processing for progressive scan is different for two successive output fields, e.g. the first output field has a median operation on the odd lines, while the second has the median operation on the even lines. PROGRESSIVE SCAN CONVERSION NON-INTERLACE MODE
SAA4990H
With non-interlaced progressive scan output, line flicker is removed because interlace is removed. INTERLACE MODE With interlaced progressive scan the output line structure and line flicker is less visible (projection TV).

Progressive scan-Zoom and Noise reduction IC (PROZONIC)
Noise and cross-colour reduction The noise reduction is field recursive with an average ratio between fresh and over previous fields averaged luminance and chrominance. Two operating modes can be used in principal: the fixed and the adaptive mode (see Table 6). In the fixed mode, the averaging produces a constant linear combination of the inputs. Except for k = 1, the fixed mode should not be used for normal operation, because of its smearing effects. In the adaptive mode, the averaging ratio switches softly on the basis of absolute differences in luminance among the inputs. When the absolute difference is low, only a small part of the fresh data will be added. When the difference is high, much of the fresh data will be taken. This occurs in either the situation of movement or where a significant vertical contrast is seen.
SAA4990H
To latter remark, note that recursion is done over a field, and the pixel positions one field apart always have a vertical offset of one frame line. So averaging is not only done in the dimension of time but also in the vertical direction. Therefore averaging vertically on e.g. a vertical black to white edge would provide a grey result if this was not adapted for. The averaging in chrominance is slaved to the luminance averaging. This implies that differences in the chrominance are not taken into account for the k-factor setting. The noise reduction scheme effectively decreases both noise and cross-colour patterns. The cross-colour pattern does not produce an increase of the measured luminance difference, therefore this pattern will be averaged over many fields.

Progressive scan-Zoom and Noise reduction IC (PROZONIC)
Vertical sample rate conversion The variable vertical sample rate conversion is performed on top of the noise reduced and progressively scanned data. The vertical sample rate conversion is intended to cope with the various letter box formats, to be displayed on displays with e.g. 16:9 aspect ratio. For this sample rate conversion, which usually has both a vertical and a horizontal component, the vertical sample rate conversion is taken care of in the PROZONIC, while the horizontal compression can be done in e.g. TDA8753A or SAA4995WP. The vertical sample rate conversion can also be used to convert from an NTSC 525 lines source to a 625 line display, by setting a vertical sample rate conversion factor of 65 and necessarily some line-time reduction. Conversion from 625 to 525 lines is possible with progressive scan output, by setting a vertical sample rate conversion of 56. The principle of vertical sample rate conversion is based on linear interpolation from two successive lines of video in a frame to produce an output line in either a field or a frame. The vertical sample rate conversion factor can be switched to the following settings for increasing the number of output lines w.r.t. the number of input lines; see Table 1.

SAA4990H
While processing video, that was originally film (25 movement phases per second in the case of 50 Hz field rates), median filtering is not needed when fields are combined that have the same movement phase. As this phase is not generally known, the PROZONIC has a detection circuit to help determine it. The detection is based on measurement of absolute luminance differences between successive input fields, pixel by pixel. These differences are summed over all active video and give a number every field. In case of video from film with sufficient movement, the measured number will alternately be HIGH and LOW. With the controlling microcontroller, this data can be filtered appropriately to switch to movie processing in the correct phase. The PROZONIC has a provision to generate a rectangular box, which is position and size programmable. This box can be used to enable the measurement in the movie phase detection circuit, only within this rectangle. Otherwise, the active video part in a field is marked with a derivative of the RE pulse. Box generation A rectangular box is defined by the coordinates of the left-upper edge (hor_start_box, vert_start_box) and the right-lower edge (hor_stop_box, vert_stop_box). The reference for the coordinates are the HD positive edge (with some processing delay) for the horizontal direction and the VD positive edge for the vertical. The box can serve the following purposes: * Switch between adaptive and fixed k in noise reduction. If k-fixed is set to 0, then the box switches between adaptive noise reduced and fully still picture areas. This provides an option for producing multi picture (still) images. If no noise reduction is desired in the area where NR is adaptive, the adaptive setting can be programmed with k steps to all zeros. * Switch the movie phase detect measurement to a defined area of the video.

Control and microcontroller (SNERT-) interface CONTROL SIGNALS
SNRST
Field frequent asynchronous reset signal, used in PROZONIC to reset the communication with microcontroller. After the rising edge of SNRST, communication is in its defined state. SNRST is also used to define the initial phase of the line-sequencer.
CK
Line-locked clock of nominal 27 or 32 MHz. This is the system clock, nominally 864 or 1024 x fh, where fh is the line frequency. Within the PROZONIC, CK is distributed to different blocks.
SNCL
microcontroller interface clock signal. This signal is transferred asynchronous to CK by a microcontroller (UART of 8051 family, mode 0) as communication clock signal at a frequency of 1 MHz.
HD
Horizontal reference signal. This signal defines with its rising edge the start phase of the UV 4 : 1 : 1 format. If the HD signal has a period equal to 4 clock periods, the UV data will remain in phase without disruptions, once it has become in phase. For any mismatch between the applied HD to the UV data phase, an appropriate HD delay can be set in the PROZONIC. HD is also used to count lines for boxing.
SNDA
microcontroller interface data signal. This signal is transferred or received (asynchronous to CK) by a microcontroller (UART of 8051 family, mode 0) as communication data signal at 1 MBaud, related to SNCL. EXTERNAL CONTROL The PROZONIC is controlled via the microcontroller (SNERT) interface, by sending an address byte and a data byte to it, with the controllable items as in the register descriptions in Tables 2 and 3.
RE
Master read enable from memory controller or ECOBENDIC. This signal controls the memory read enable if only one field memory is present. To control two field memories, the PROZONIC generates RE1, RE2 and WE2 from RE. The vertical sample rate conversion function has a major influence on these signals.
RE1
Read enable for FM1, processed from RE by PROZONIC.

Microcontroller interface (SNERT) In the microcontroller interface the external signals SNDA and SNCL are processed to address and data. Data enable pulses are derived from the received addresses. The data enable pulses are used elsewhere for input enabling the delivered data into various control registers. The microcontroller interface operates in a few stages: 1. SNCL positive and negative edges are sampled 2. on each negative edge of SNCL and SNDA data is shifted in a shift register 3. starting from phase 0, a counter counts positive edges of SNCL 4. during phase 7, but waited for a negative edge of SNCL, so after the 8th negative edge of SNCL, an address latch enable pulse is made, whereby the shift register contents are taken over in the address register 5. in the address range 10H to 27H, the addresses are decoded in two steps 6. during phase 15, but waited for a negative edge of SNCL, so after the 16th negative edge of SNCL, the address has been decoded and will be passed to any of the data enable pulses.

For each of the functions vert_start_box and vert_stop_box, two addresses are used, in which the LSB from the address is taken as an extra MSB for the data. This is done because vert_start_box and vert_stop_box must be supplied with 9-bit data. All other data from the SNERT-bus has only relevance in the 7:0 range. During the data phases (phase 8 to 15), each negative edge produces a shift pulse for the movie phase detect circuit that produces output data on the SNDA signal. The data enables for the movie phase detect circuit are active in all of the data phases, when an address 26 or 27 has been decoded. After an MPD read transmission it is necessary to send a second (dummy) transmission to the PROZONIC.

APPLICATION INFORMATION The basic application of PROZONIC in a feature box is shown in Fig.15. Here, apart from the data streams, the `timed control data' streams indicate that some memory control signals have to be processed by the PROZONIC, in order to let the vertical sample rate conversion function correctly. Horizontal scaling factors are performed by the memory controller SAA4951WP/SAA4952H. All basic clock signals in the feature box are provided by the memory controller, nominal frequencies on the double scan parts of the system are 27, 32 or 36 MHz. In any case the display frequency is decoupled from the acquisition clock. The memory controller supplies the deflection processor with clock, horizontal and vertical pulses. The SNERT-bus is used to control the PROZONIC at a data rate of typically 1 Mbits/s.

SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). Reflow soldering Reflow soldering techniques are suitable for all QFP packages. The choice of heating method may be influenced by larger plastic QFP packages (44 leads, or more). If infrared or vapour phase heating is used and the large packages are not absolutely dry (less than 0.1% moisture content by weight), vaporization of the small amount of moisture in them can cause cracking of the plastic body. For more information, refer to the Drypack chapter in our "Quality Reference Handbook" (order code 9397 750 00192). Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. Several techniques exist for reflowing; for example, thermal conduction by heated belt. Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 C. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 C. Wave soldering Wave soldering is not recommended for QFP packages. This is because of the likelihood of solder bridging due to closely-spaced leads and the possibility of incomplete solder penetration in multi-lead devices.
SAA4990H
If wave soldering cannot be avoided, the following conditions must be observed: * A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. * The footprint must be at an angle of 45 to the board direction and must incorporate solder thieves downstream and at the side corners. Even with these conditions, do not consider wave soldering the following packages: QFP52 (SOT379-1), QFP100 (SOT317-1), QFP100 (SOT317-2), QFP100 (SOT382-1) or QFP160 (SOT322-1). During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. Maximum permissible solder temperature is 260 C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 C within 6 seconds. Typical dwell time is 4 seconds at 250 C. A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. Repairing soldered joints Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 C.
