2004 mar 03 41 philips semiconductors product speci?cation pal/ntsc/secam video decoder with adaptive pal/ntsc comb ?lter, vbi data slicer and high performance scaler saa7114 8.3 scaler the high performance video scaler (hps) is based on the system as implemented in previous products (e.g. saa7140), but with some aspects enhanced. vertical upsampling is supported and the processing pipeline buffer capacity is enhanced, to allow more flexible video stream timing at the image port, discontinuous transfers, and handshake. the internal data flow from block to block is discontinuous dynamically, due to the scaling process. the flow is controlled by internal data valid and data request flags (internal handshake signalling) between the sub-blocks; therefore the entire scaler acts as a pipeline buffer. depending on the actually programmed scaling parameters the effective buffer can exceed to an entire line. the access/bandwidth requirements to the vga frame buffer are reduced significantly. the high performance video scaler in the saa7114 has the following major blocks: acquisition control (horizontal and vertical timer) and task handling (the region/field/frame based processing) prescaler, for horizontal downscaling by an integer factor, combined with appropriate band limiting filters, especially anti-aliasing for cif format brightness, saturation, contrast control for scaled output data line buffer, with asynchronous read and write, to support vertical upscaling (e.g. for videophone application, converting 240 into 288 lines, y-c b -c r 4:2:2) vertical scaling, with phase accurate linear phase interpolation (lpi) for zoom and downscale, or phase accurate accumulation mode (acm) for large downscaling ratios and better alias suppression variable phase delay (vpd), operates as horizontal phase accurate interpolation for arbitrary non-integer scaling ratios, supporting conversion between square and rectangular pixel sampling output formatter for scaled y-c b -c r 4:2:2, y-c b -c r 4:1:1 and y only (format also used for raw data) fifo, 32-bit wide, with 64 pixel capacity in y-c b -c r formats output interface, 8 or 16-bit (only if extended by h port) data pins wide, synchronous or asynchronous operation, with stream events on discrete pins, or coded in the data stream. the overall h and v zooming (hv_zoom) is restricted by the input/output data rate relationships. with a safety margin of 2% for running in and running out, the maximum hv_zoom is equal to: for example: 1. input from decoder: 50 hz, 720 pixel, 288 lines, 16-bit data at 13.5 mhz data rate, 1 cycle per pixel; output: 8-bit data at 27 mhz, 2 cycles per pixel; the maximum hv_zoom is equal to: 2. input from x port: 60 hz, 720 pixel, 240 lines, 8-bit data at 27 mhz data rate (itu 656), 2 cycles per pixel; output via i + h port: 16-bit data at 27 mhz clock, 1 cycle per pixel; the maximum hv_zoom is equal to: the video scaler receives its input signal from the video decoder or from the expansion port (x port). it gets 16-bit y-c b -c r 4:2:2 input data at a continuous rate of 13.5 mhz from the decoder. discontinuous data stream can be accepted from the expansion port (x port), normally 8-bit wide itu 656 such as y-c b -c r data, accompanied by a pixel qualifier on xdq. the input data stream is sorted into two data paths, one for luminance (or raw samples) and one for time multiplexed chrominance c b and c r samples. an y-c b -c r 4:1:1 input format is converted to 4 :2:2 for the horizontal prescaling and vertical filter scaling operation. the scaler operation is defined by two programming pages a and b, representing two different tasks, that can be applied field alternating or to define two regions in a field (e.g. with different scaling range, factors and signal source during odd and even fields). each programming page contains control: for signal source selection and formats for task handling and trigger conditions for input and output acquisition window definition for h-prescaler, v-scaler and h-phase scaling. raw vbi data is handled as a specific input format and needs its own programming page (equals own task). 0.98 t_input_field t_v_blanking C in_pixel in_lines out_cycle_per_pix t_out_clk ------------------------------------------------------------------------------------------------------------------------------- ------ - 0.98 20 ms 24 64 m s C 720 288 2 37 ns -------------------------------------------------------- 1.18 = 0.98 16.666 ms 22 64 m s C 720 240 1 37 ns -------------------------------------------------------------- 2.34 =
2004 mar 03 42 philips semiconductors product speci?cation pal/ntsc/secam video decoder with adaptive pal/ntsc comb ?lter, vbi data slicer and high performance scaler saa7114 in vbi pass through operation the processing of prescaler and vertical scaling has to be set to no-processing, however, the horizontal fine scaling vpd can be activated. upscaling (oversampling, zooming), free of frequency folding, up to a factor of 3.5 can be achieved, as required by some software data slicing algorithms. these raw samples are transported through the image port as valid data and can be output as y only format. the lines are framed by sav and eav codes. 8.3.1 a cquisition control and task handling ( subaddresses 80h, 90h, 91h, 94h to 9fh and c4h to cfh) the acquisition control receives horizontal and vertical synchronization signals from the decoder section or from the x port. the acquisition window is generated via pixel and line counters at the appropriate places in the data path. from x port only qualified pixels and lines (lines with qualified pixel) are counted. the acquisition window parameters are as follows: signal source selection regarding input video stream and formats from the decoder, or from x port (programming bits scsrc[1:0] 91h[5:4] and fsc[2:0] 91h[2:0]) remark : the input of raw vbi data from the internal decoder should be controlled via the decoder output formatter and the lcr registers; see section 8.2 vertical offset defined in lines of the video source, parameter yo[11:0] 99h[3:0] 98h[7:0] vertical length defined in lines of the video source, parameter ys[11:0] 9bh[3:0] 9ah[7:0] vertical length defined in number of target lines, as a result of vertical scaling, parameter yd[11:0] 9fh[3:0] 9eh[7:0] horizontal offset defined in number of pixels of the video source, parameter xo[11:0] 95h[3:0] 94h[7:0] horizontal length defined in number of pixels of the video source, parameter xs[11:0] 97h[3:0] 96h[7:0] horizontal destination size, defined in target pixels after fine scaling, parameter xd[11:0] 9dh[3:0] 9ch[7:0]. the source start offset (xo11 to xo0 and yo11 to yo0) opens the acquisition window, and the target size (xd11 to xd0 and yd11 to yd0) closes the window, however the window is cut vertically if there are less output lines than expected. the trigger events for the pixel and line counts are the horizontal and vertical reference edges as defined in subaddress 92h. the task handling is controlled by subaddress 90h; see section 8.3.1.2. 8.3.1.1 input ?eld processing the trigger event for the field sequence detection from external signals (x port) are defined in subaddress 92h. from the x port the state of the scalers h reference signal at the time of the v reference edge is taken as field sequence identifier fid. for example, if the falling edge of the xrv input signal is the reference and the state of xrh input is logic 0 at that time, the detected field id is logic 0. the bits xfdv[92h[7]] and xfdh[92h[6]] define the detection event and state of the flag from the x port. for the default setting of xfdv and xfdh at 00 the state of the h-input at the falling edge of the v-input is taken. the scaler directly gets a corresponding field id information from the saa7114 decoder path. the fid flag is used to determine whether the first or second field of a frame is going to be processed within the scaler and it is used as trigger condition for the task handling (see bits strc[1:0] 90h[1:0]). according to itu 656, when fid is at logic 0 means first field of a frame. to ease the application, the polarities of the detection results on the x port signals and the internal decoder id can be changed via xfdh. as the v-sync from the decoder path has a half line timing (due to the interlaced video signal), but the scaler processing only knows about full lines, during 1st fields from the decoder the line count of the scaler possibly shifts by one line, compared to the 2nd field. this can be compensated for by switching the v-trigger event, as defined by xdv0, to the opposite v-sync edge or by using the vertical scalers phase offsets. the vertical timing of the decoder can be seen in figs 22 and 23. as the h and v reference events inside the itu 656 data stream (from x port) and the real-time reference signals from the decoder path are processed differently, the trigger events for the input acquisition also have to be programmed differently.
