LG Electronics Assigned Patent for DTV Receiver and Method of Processing Broadcast Signal

Strategic Insights

— 1 min read

LG Electronics, Seoul, South Korea, has been assigned a patent developed by seven co-inventors for a "DTV receiver and method of processing broadcast signal in DTV receiver." The co-inventors, namely Byoung Gill Kim, In Hwan Choi, Woo Chan Kim, Jae Hyung Kim, Yong Hak Suh, Hyoung Gon Lee, and Jong Moon Kim, have successfully created a device that can receive and process digital television (DTV) signals. The patent's abstract describes the device as having a tuner, a demodulator, a known sequence detector, and a frequency domain equalizer. This setup enables the device to initially receive a broadcast signal, demodulate it, detect a known sequence, and then compensate for channel distortion in the frequency domain using the detected sequence.

Key Takeaways:

  • The patented DTV receiver and method of processing broadcast signal (8,050,316) was developed by seven co-inventors, Byoung Gill Kim, In Hwan Choi, Woo Chan Kim, Jae Hyung Kim, Yong Hak Suh, Hyoung Gon Lee, and Jong Moon Kim.
  • The DTV receiver includes a tuner, a demodulator, a known sequence detector, and a frequency domain equalizer.
  • The device initially receives a broadcast signal, demodulates it, detects a known sequence, and then compensates for channel distortion in the frequency domain using the detected sequence.
  • The patent application was filed on December 20, 2006 (11/613,923).
  • The DTV receiver may also include a time domain equalizer to further compensate for channel distortion in the time domain signal, or a noise canceller to remove predicted noise from the time domain signal.
