Toronto, Canada - GAO Research Inc. (www.GAOResearch.com) has enhanced its V.22bis & V.22 modem software for better performance. The software modules implement the ITU-T standards for 1200bps and 2400bps full-duplex data communication on the GSTN and on point-to-point two-wire leased line circuits.

Toronto, Canada - GAO Research Inc. (www.GAOResearch.com) has enhanced its V.22bis & V.22 modem software for better performance. The software modules implement the ITU -T standards for 1200bps and 2400bps full -duplex data communication on the GSTN and on point -to -point two -wire leased line circuits.

In these modems, channels are separated by frequency division and each channel is phase shift modulated. A symbol rate of 600 carries 2bits per symbol at a rate of 1200bps for V.22. For V.22bis, each channel is quadrature amplitude modulated (QAM) to carry 4bits per symbol at 600 symbols per second at a rate of 2400bps. Carrier frequencies are 1200Hz and 2400Hz respectively for the low and high channels. The software has been tested against various impairment combinations using TAS (Telephone Network Emulator).
The software supports commonly used processors such as TI C5000 & C6000 series DSPs, ARM processors and ADI DSPs and OS such as Windows, VxWorks, and Linux.

PureLink - HCE III TX/RX: 4K HDR over HDBaseT Extension System w/ Control and Bi-Directional PoE

The HCE III Tx/Rx HDBaseT™ extension system offers full HDMI 2.0 compliance supporting HDR (High Dynamic Range) and 4K@60Hz with 4:4:4 chroma sampling. Featuring PureLink's proprietary Prcis codec, a light compression technology, the HCE III can transport Ultra HD/4K, multi-channel audio, and High Dynamic Range (10 bits support) content over a single CATx cable. The HCE III provides HDMI extension up to 130 feet (40 meters) at Ultra HD/4K and up to 230 ft. (70 meters) at 1080p over category cable with embedded multi-channel audio, CEC pass-through, bi-directional RS-232 and IR control, and PoE - all with zero loss and zero noise. The HCE III Tx/Rx also supports Dolby TrueHD, Dolby Digital Plus and DTS-HD Master Audio plus LCPM (up to 192 kHz). Additionally, the low profile "slim box" enclosure design make the HCE III ideal for limited space installation environments, such as behind flat panel displays and video walls.
