Blonder Tongue Laboratories will demonstrate its newest solutions for HDTV, SDTV and IPTV applications including the IPAT, HDE-2H-QAM and HDE-2S-QAM, and SD/AV10E-QAM at the NAB Show in April in Las Vegas.The IPAT is the company's latest release. Designed for IPTV applications, the IPAT is a bi-direction ASI-to-IP transcoder, which accepts MPEG2/4-encoded input streams in 1000Base-T Ethernet (GigE) and ASI formats simultaneously. GigE input is transcoded to ASI output while ASI input is transcoded to GigE output. Two optional modules allow input/output in QAM and 8-VSB formats. The product is expected to ship in the second quarter.The HDE-2H-QAM is a 2:1 encoder and multiplexer designed to accept up to two inputs in HDMI and component formats, digitize and MPEG-2 encode each into a HD (1080i/720p) stream, and multiplex the resulting two streams into one QAM output. Any combination of input multiplexing is allowed. It supports Dolby Digital AC-3 encoding and Closed Captioning (EIA-608), and is equipped with an EAS interface. The HDE-2S-QAM is identical to HDE-2H-QAM, but accepts two inputs in HD-SDI and component formats. HDE-2S-QAM is expected to ship in the second quarter.The SD/AV10E-QAM is a 10:1 encoder and multiplexer designed to accept up to 10 inputs in SD-SDI and NTSC Audio/Video formats, digitize and MPEG-2 encode each input, and multiplex the resulting 10 streams into one QAM output. It supports Dolby Digital AC-3 encoding and closed captioning, and is equipped with an EAS interface.
