CRC posted test results for two Linx (now Micronas) ATSC Receiver Prototypes (Apr02 and Mar03) and a Zenith/LG ATSC Receiver Prototype (Sep03). CRC has not posted the fol. report on a Samsung ATSC Receiver Prototype: http://www.crc.ca/en/html/crc/home/research/broadcast/rtnt "Lab. Eval. of a Prototype Samsung ATSC Receiver" dtg 30Aug05. The Samsung prototype uses a commercially available ALPS Tuner Module and Samsung's "Gemini" ATSC Decoder chip (whatever that is...) The ALPS Tuner Module has a desired signal overload point of +1.5 dBm and a sensitivity of -84.7 dBm (that's a Noise Figure of about 6 dB). Perhaps it's the Alps Electric TEQH Tuner Module??? Samsung performance met all ATSC A/74 Guidelines (unlike other tested prototypes), with performance under most test conditions, exceeding the performance of both the Zenith/LG Prototype and the two versions of Linx (now Micronas) Prototypes. Under marginal SNR conditions, the Samsung could not handle low delay echos (< 1 usec, i.e. less than 0.2 mile path differential), where the multipath components are within a few dB of each other. This can occur when there are nearby reflecting objects (e.g. your neighbor's house and/or your interior/attic location). Nonetheless the Samsumg Prototype still outperformed the Linx and especially the Zenith/LG Prototypes under these so-called "zero echo" test conditions. As always, these are results for PROTOTYPE equipments and may or may not be representative of (hopefully improved) production equipment. I also have been unable to determine exactly WHAT was in the Linx (Micronas) and Zenith/LG Prototypes relative to production chips.... --------------------------------- Yahoo!
