Video security encoders get a boost via McVFE

Electronics design services firm Nuvation introduces the Multichannel Video Front End (McVFE) reference design for accelerating new product development of video security multichannel encoders. Nuvation's McVFE reference design is based on Texas Instruments' DaVinci technology and TVP quad-channel video decoder with complementary FPGA technology provided by Xilinx's Spartan 3A FPGA technology.

Engineering evaluation units are available for purchase and the reference design source files can be licensed, free of charge, from Nuvation.

According to Nuvation, it positions its new McVFE reference design for video security OEMs that need to aggregate multiple CCTV video streams for encoding in TI digital media processors based on DaVinci technology. The McVFE reference design supports 4, 8, or 16 analog video channel inputs from CIF to NTSC/PAL resolution. The video channels can be scaled through the McVFE's four TI TVP5154A quad-channel low power video decoders. The video streams are time-multiplexed in line, field, or frame mode in a Xilinx Spartan-3A FPGA. The video is streamed over BT-1120 from the McVFE board to a TMS320DM6467 digital video evaluation module (DVEVM) via a special adapter card and cable kit also available from Nuvation. Drivers based on TI's DaVinci technology are included with McVFE to receive the BT-1120 input and tile the streamed video to a 1080i component display.

The DM6467 processor, based on DaVinci technology, integrates a high-definition (HD)-capable TMS320C64x+ DSP core, an HD multiformat encode and decode coprocessor, an ARM926E microprocessor, PCI, USB 2.0, DDR2, and 10/100/1000 Ethernet MAC.
