This IP is a highly versatile video multiplexer that allows one video stream to be inserted over another. By cascading a series of video overlay modules together, any number of video sources may be multiplexed together. The module supports input video streams of any resolution or aspect ratio up to 216 x 216 pixels in size. Video overlay parameters may be changed on a frame-by-frame basis to dynamically change the size and position of the video overlay.
Pixels and syncs flow in and out of the video overlay module in accordance with the valid-ready pipeline protocol. The pipeline protocol allows both input and output interfaces to be stalled independently.
In addition, the overlay module supports a number of blending operations including an 8-bit alpha channel and bitwise AND, OR and XOR functions.
Application
Network and Tactical operations centres
Digital-video special effects
Broadcast TV and film production
CCTV and security camera systems

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
BT.656 output video generation
PAL & NTSC SDTV video format conversion

The IP Core is a highly versatile On Screen Display (OSD) module that allows text and bitmap graphics to be inserted over RGB video. The module supports a wide range of text effects and the
programming interface is very simple. Text is written to a 64x32 character buffer which is mapped (via a bitmap ROM) directly to the display.
The characters in the buffer are displayed in a 'TEXT BOX' which may be positioned anywhere in the video display area. Bitmaps for each character are stored in a ROM which may be modified to support different font styles or bitmap graphics.
Pixels and syncs flow in and out of the overlay module in accordance with the valid-ready pipeline protocol.
Application
Window movement in the same manner as a 2D 'BitBlt'
Terminal and Console windows
Low cost text and graphics applications

This is a highly versatile on-screen display that allows high-quality anti-aliased bitmap graphics to be inserted over RGB video. The module supports a wide range of graphics effects and the programming interface is very simple to use. The bitmap overlay is partitioned into an array of tiles which are addressed by means of an 8-bit value stored in a 64x64 tile buffer. There are four tile sizes available - either 8x8, 16x16, 32x32 or 64x64.
The tiles in the buffer are displayed in a graphics window which may be positioned anywhere within the display area. Bitmaps for each tile are stored in a user-defined ROM which can contain up to 256 different bitmaps stored over three bit-planes. Depending on the chosen graphics mode, the 3-bits per pixel may be used to select one colour from a palette of eight, eight levels of alpha transparency or seven colours on a transparent background.
Pixels and syncs flow in and out of the overlay module in accordance with the valid-ready pipeline protocol.
Application
Animated 2D graphics including hardware sprites, mouse pointers, cursors , parallax scrolling, moving banners etc.
Interactive guides, menus, tables, lists etc.

Motion-adaptive Video Deinterlacer |

The IP Core is a studio quality 24-bit RGB video deinterlacer capable of generating progressive output video at any resolution up to 216 x 216 pixels. The design is fully programmable and supports any desired interlaced video format.
The design allows for three possible deinterlacing schemes. These are: weave, bilinear interpolation or motion-adaptive interpolation. The weave approach applies no filtering and may be useful to obtain a 'raw' interlaced format for subsequent processing. The other two methods are classed as 'inter-field' interpolation methods as spatial filtering is performed between both odd and even fields to achieve a clean and progressive output. The relative merits and disadvantages of each scheme are discussed further into the document.
The deinterlacer core features a fully integrated video frame buffer. This buffer is completely 'elastic' and will dynamically skip and/or repeat frames depending on the input and output frame rates. All frame buffer management is handled internally with the provision of a simple memory interface for storing odd and even fields off-chip. The memory interface is 128-bits wide and is completely generic. All memory transfers are sequential bursts of N x 128-bit words and may be adapted for connection to a variety of memory types such as SDRAM, DDR2 or DDR3.
Application
Digital TV set-top boxes. Industrial imaging. Automotive, home and personal media solutions
Conversion of 'legacy' SDTV formats to HDTV video formats

The IP Core is a high quality 24-bit RGB video deinterlacer capable of generating progressive output video at up to 4096x4096 pixels in resolution. The design is fully customizable, supporting any desired interlaced video format.
The deinterlacer allows for three possible filter algorithms - either BOB, ELA or LCI. All three methods are 'intra-field' methods that perform spatial filtering within the same field. For this reason, the output video is not subject to combing or tearing which is characteristic of a traditional 'weave' approach.
Each algorithm has it relative merits in terms of image quality and hardware complexity. In particular, the enhanced LCI algorithm provides excellent all-round performance with reduced image softening and crisp clean edges.
