Harnessing the processing power of Stratix II GX transceiver-based FPGAs from Altera, Axon Digital Design has created a quad split module that is said to be the market’s first video signal processing product to support triple-rate serial digital interface (SDI) standards.
Key applications for the module include high-resolution monitor walls used in the surveillance industry and truck preview monitoring and shading equipment used to deliver live television broadcasts.
With the GQW200, broadcast studio engineers can readily accommodate 270 Mbps, 1,5 Gbps and 3 Gbps SDI signals. The device offers four triple-rate SDI inputs, two triple-rate SDI outputs, or a digital video interface (DVI) output. The module adapts instantly to the three different transmission rates, enabling broadcast studio engineers to work easily with a mix of equipment conforming to standard- and high-definition (HD) formats.
The GQW200 module runs on the Linux operating environment. Its processing power comes primarily from a Stratix II GX FPGA, which supports automatic switching between SDI, HD-SDI and 3 Gbps SDI data speeds with up to 20 triple-rate SDI full-duplex transceiver channels operating across a range of 270 Mbps to 3 Gbps.
Stratix II GX FPGAs offer generous on-chip memory, external DDR2 memory interfaces and powerful digital signal processing (DSP) resources, which are an ideal fit for implementing the post-processing features offered by the GQW200, including colour space conversion, gain, sharpness, graphic overlay and overlay insertion. By leveraging Stratix II GX devices, Axon was able to reduce component count compared to its prior quad split product, which increases the product’s overall reliability, lowers manufacturing cost and reduces form factor.
The Altera Audio Video Development Kit, Stratix II GX Edition, was integral in helping Axon meet its aggressive product development timeline. Broadcast equipment manufacturers can develop triple-rate SDI-based products by taking advantage of this kit, which includes a development board, Quartus II design software, evaluation intellectual property (IP) cores, the SDI reference design and documentation. The kit allows broadcast audio and video equipment designers to develop their systems on a single programmable platform while addressing cost, performance, quality and time-tomarket requirements.
