Patent number: 8130873Abstract: A carrier recovery apparatus usable with a VSB receiver and a method thereof. The carrier recovery apparatus is capable of recovering a carrier even though a pilot signal may be corrupted due to multi-path characteristics of a channel. Accordingly, the carrier recovery apparatus performs a BECM (Band Edge Component Maximization) algorithm on upper and lower sidebands of a received signal to generate phase information therefrom. The phase information is combined in a combiner. Since the BECM algorithm is performed on the upper and lower sidebands, it is possible to execute the carrier recovery even through the upper sideband of a received signal may be corrupted. Therefore, the carrier recovery apparatus can prevent performance degradation of the VSB receiver caused by corruption in the pilot signal.Type: GrantFiled: August 9, 2005Date of Patent: March 6, 2012Assignee: Samsung Electronics Co., Ltd.Inventor: Dong-hoon Lee

Patent number: 8040438Abstract: The present invention offers a method for channel change in digital broadcasting consisting of: a step 1 for recognizing a command for a channel change while the currently connected channel is being decoded at the digital broadcasting terminal; a step 2 for completing reception of the current stream while maintaining the received picture if there is a command for a channel change according to said step 1; a step 3 for receiving and analyzing the information of the newly concatenated stream without re-initializing the decoder and concatenating two streams; and a step 4 for renewing information of the newly concatenated stream in order to maintain continuity between the previous stream and the newly concatenated stream using the information obtained in said steps 2 and 3. Therefore, time delay during channel change will be minimized by changing channels without decoder re-initialization and without break in the channel changing time.Type: GrantFiled: September 17, 2007Date of Patent: October 18, 2011Assignee: Castis Co., Ltd.Inventors: Seung Hak Kim, Bo Kyoung Yoon, Hoon Park

Publication number: 20110249192Abstract: Rate matching for use in data links between a source device and a sink device is provided. A rate matching device includes a first-in-first-out (FIFO) buffer having a write pointer and a read pointer; a write control having a write clock to write an input data stream from the source device onto the FIFO buffer using the write pointer; a read control having a read clock to read data from the FIFO buffer using a read pointer, insert data to an output data stream and transmitting the data stream to the sink device; a processor to provide a bit number based on the write clock period and the read clock period, wherein the read control inserts blanking data into the output data stream while the read pointer is stopped in the FIFO buffer to allow the write pointer to move ahead by the bit number provided by the processor. Some embodiments are thus able to avoid buffer overflow or underflow scenarios.Type: ApplicationFiled: April 7, 2010Publication date: October 13, 2011Inventor: Prashant Shamarao

Patent number: 8036621Abstract: There is provided a receiving apparatus having a simple configuration and an excellent ability to eliminate multipath noise, in which an antenna in a good reception state can be instantly selected. A reception signal from an antenna is inputted to an intermediate-frequency amplifying circuit via an antenna switching circuit, a front end and an A/D converting circuit, and an S meter signal from an S meter circuit is inputted to a controlling section via a noise detecting filter and an absolute value circuit. Then, the controlling section compares noise components outputted from the absolute value circuit (noise level) with a threshold value Vth outputted from a threshold value setting section. When the noise level becomes higher than the threshold value Vth, an antenna selection controlling signal is outputted to the antenna switching circuit, and antennas are switched.Type: GrantFiled: April 4, 2006Date of Patent: October 11, 2011Assignee: Fujitsu Ten LimitedInventor: Kiyotaka Nakagawa

Patent number: 8035754Abstract: First and second signal processing units are each configured by an IC, so that the circuit space occupying in a receiver apparatus can be reduced. The signal path can be shortened from a BPF section inputting a program signal coming from a broadcasting station to a demodulation section compared with the related art. The transmission loss on the signal path can be thus reduced compared with the related art. The possible route for noise entering from the outside to the first and second signal processing units can be made as short as possible. This enables to reduce the noise entering from the outside, and prevents the signals coming over the signal path from being attenuated by the noise so that the signal reception sensitivity can be increased.Type: GrantFiled: July 25, 2006Date of Patent: October 11, 2011Assignee: Sharp Kabushiki KaishaInventors: Hiroyuki Shoji, Yoshikazu Suga, Kouichi Aoto
