The IP module is a versatile test pattern generator capable of producing a range of test patterns in colour, greyscale and monochrome formats. The module is invaluable in the prototyping stages
of digital video systems. In addition, the test pattern generator may be used to provide a blank background display.
The video output resolution is controlled by the generic parameters "PPL" and "LPF". The colour, type and dimensions of the test pattern are determined by the parameters INTL, MODE, TYPE and LOG2W.
Application
Generation of a blank video background
Simple screen savers

The IP Core is a fully pipelined video interlacer solution that converts any progressive video format into it's interlaced equivalent. Each interlaced output field will have half the number of lines as an input frame.
The input and output interfaces are streaming interfaces that follow a simple valid-ready pipeline protocol. Input pixels and syncs are sampled on the rising edge of clk when P_VALID and P_READY are both high. Likewise, output pixels and syncs are sampled on the rising edge of clk when PO_VAL and PO_READY are high.
Note that if no flow control is required in the design and the output is guaranteed to accept pixels without stalling, then the signal PO_READY may be tied high and the signal P_READY may be ignored.
Application
Video solutions for flat panel displays, portable devices, video consoles, video format converters, set-top boxes, digital TV etc.
Conversion of all standard and custom video formats such as 1920x1080p to 1920x1080i, 720x480p to 720x480i etc.

The IP Core is a fully configurable video timing generator with the ability to support any video resolution up to 216 x 216 pixels in size. The module is compatible with a wide range of video DACs, CODECs and transceivers and provides a flexible solution for displaying digital or analogue video on an external TV, monitor or flat panel display. The module is capable of clock speeds in excess of 400 MHz on some FPGA platforms, making it ideal for the latest generation HD and UHD video solutions.
After resynchronizing the input pixels to the pixel-clock domain , the controller locks to the first frame (or field) of video. Once frame-lock is achieved, pixels are supplied on demand to the video timing control unit. This module generates the correct RGB video, sync and blanking information depending on the chosen timing parameters.
Application
Legacy (SD) and analogue video applications
Digital TV and multimedia solutions
HD, UHD and SUHD next generation digital video

The IP Core is a fully pipelined chroma resampler that converts pixels between 4:4:4 and 4:2:2 formats in the YCbCr colour space. In total, the IP Core package contains two distinct modules – one module that converts from 4:4:4 to 4:2:2 and the other that performs the reciprocal operation from 4:2:2 to 4:4:4.
Pixels flow into the design in accordance with the valid ready pipeline protocol. Input pixels and syncs are sampled on the rising edge of clk when PIX_VALID and PIX_READY are both high. At the output interface, pixels and syncs are sampled on a the rising edge of clk when POUT_VALID and POUT_READY are high. The input and output sync signals are coincident with the first pixel of a frame and the first pixel of a line. These are useful to identify the video frame and line boundaries.

VID_FB is a high-speed multi-format video frame buffer that asynchronously samples an input video stream and buffers it in an external memory. Output pixels are read out of the buffer and synchronised to the system clock domain.
The VID_FB will automatically adapt to different input and output frame rates. If the input frame rate is too high, then the VID_FB will cleanly drop or 'skip' an input frame. Likewise, if the output frame rate is higher than the input frame rate, then frames will be repeated 3 . The result is a system that seamlessly adapts to the different frame rates at the input and output of the VID_FB.
Applications
Buffering video frames in external memory
Real-time digital video applications

The IP Core is a studio quality video scaler capable of generating interpolated output images from 16 x 16 up to 216 x 216 pixels in resolution. The architecture permits seamless scaling (either up or down) depending on the chosen scale factor. Internally, the scaler uses a 24-bit accumulator and a bank of polyphase FIR filters with 16 phases or interpolation points. All filter coefficients are programmable, allowing the user to define a wide range of filter characteristics.
Pixels flow in and out of the video scaler in accordance with the valid-ready pipeline protocol. Pixels are transferred into the scaler on a rising clock-edge when pixin_val is high and pixin_rdy is high. As such, the pipeline protocol allows both input and output interfaces to be stalled independently.
The scaler is partitioned into a horizontal scaling module in series with a vertical scaling module .
Application
Support for the latest generation video formats with resolutions of 4K and above
Video scaling for flat panel displays, portable devices, video consoles, video format converters, set-top boxes, digital TV etc.
Conversion of all standard and custom video resolutions such as HD720P to HD1080P, XGA to VGA etc.

ITU-R_BT is a digital video encoder with integrated colour-space converter. The encoder accepts 24-bit RGB pixels from sequential odd and even fields. These pixels are then mapped to the YCbCr colour-space and formatted correctly into a BT output stream.
The output of the encoder generates an industry standard ITU-R BT.656 format video stream together with a video_val signal that is asserted with the first valid byte of the output stream.
Applications
