Title: **Innovative Contributions of Tian-Min Liu in High Definition Television Technology**
Introduction
Tian-Min Liu, a remarkable inventor based in Laguna Niguel, California, has made significant strides in the realm of telecommunications and broadcasting technology. With an impressive portfolio of 20 patents, he stands out as a key figure in the development of advanced systems that enhance the performance of high-definition television (HDTV) receivers.
Latest Patents
Among his latest patents is the invention titled "Equalization and decision-directed loops with trellis demodulation in high definition TV." This innovative technology offers improved decision feedback equalizer and decision-directed timing recovery systems designed for dual mode QAM/VSB (Quadrature Amplitude Modulation/Variable Symbol Rate) receiver systems. The patent describes a trellis decoder that works in conjunction with a decision feedback equalizer (DFE) circuit on trellis-coded 8-VSB modulated signals. The trellis decoder features a 4-state traceback memory circuit that outputs maximum likelihood decisions and several intermediate decisions based on the maximum likelihood sequence path. Notably, the technology ensures that both input signals in the timing recovery system loops bear the same timestamp, thus enhancing the DFE's ability to operate effectively even in low signal-to-noise ratio (SNR) environments.
