System And Method Of Performing Digital Multi-Channel Audio Signal Decoding

View page
US Patent:
7079657, Jul 18, 2006
Filed:
Feb 26, 2002
Appl. No.:
10/083052
Inventors:
David Chaohua Wu - San Diego CA, US
Hoang Nhu - Irvine CA, US
Russ Lambert - Fountain Valley CA, US
Alexander G. MacInnis - Los Altos CA, US
Ronald Crochiere - San Diego CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
H04H 5/00
US Classification:
381 2
Abstract:
A system and method are disclosed for performing digital multi-channel decoding of a BTSC composite audio signal. Analog-to-digital conversion is performed on a composite analog audio signal at a fast clock rate to generate a composite digital audio signal at a first sample rate. Digital frequency compensation is performed on the composite digital audio signal at the first sample rate to generate a compensated composite audio signal. Digital channel demodulation and filtering are performed on the compensated composite audio signal at the first sample rate to generate a first single channel audio signal at a second sample rate.

Methods And Systems For Sample Rate Conversion

View page
US Patent:
7409339, Aug 5, 2008
Filed:
Aug 15, 2003
Appl. No.:
10/641034
Inventors:
Hoang Nhu - Irvine CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
G10L 19/14
G10L 21/00
H04B 15/00
US Classification:
704211, 381 944, 704205
Abstract:
Methods and systems for sample rate conversion convert a sampled signal to a higher data rate signal. Conversion pulses are received, having a conversion rate that is higher than the sample rate of the sampled signal. Sample points are then reconstructed from the sampled signal, in real time, on either side of a conversion pulse. An interpolation is performed between the reconstructed sample points, at the time of the conversion pulse. The interpolation results are outputted in real time. The process is repeated for additional conversion pulses. The outputted interpolated amplitudes form the higher data rate signal having a data rate equal to the conversion rate. Sample rate conversion is thus performed in real time according to the higher data rate clock, rather than with fixed ratios. As a result, when the higher data rate clock is affected by, for example, jitter or other frequency variations, the higher data rate samples immediately track the lower data rate samples. This helps to insure that the output higher data rate data tracks the lower rate data, thus providing a more accurate sample rate conversion.

Method And System For Detecting Signal Modes In A Broadcast Audio Transmission

US Patent:
7457420, Nov 25, 2008
Filed:
Aug 15, 2003
Appl. No.:
10/641004
Inventors:
Hoang Nhu - Irvine CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
H04H 20/47
H04H 20/88
H04H 40/36
H04H 20/48
H04H 40/54
H04J 15/00
H04R 5/00
H04N 7/00
H04N 5/60
US Classification:
381 11, 381 2, 381 10, 381 12, 381 22, 348481, 348483, 348485, 348738
Abstract:
A Japanese BTSC audio broadcast signal has three modes of transmission: mono, stereo, or dual mono. The control channel centering at 3. 5 fH is one of the three channels in the J-BTSC signal, and contains information to indicate to the decoder which one of the three modes the audio transmission is in. The present invention uses a bandpass filter directly in the AM band, followed by envelope filtering and a decision circuit. Therefore, the need for AM demodulation and AM carrier detection is eliminated.

Abstract:
A television on a chip (TVOC) system that provides a cost effective approach for providing television functionality on a single integrated circuit chip is disclosed. A TVOC includes the functionality necessary to receive and display television signals in a variety of input and output formats. A TVOC can be used in set-top boxes for cable and satellite television, or directly within a television. All functionality provided can be provided on a single integrated circuit. TVOC includes a data transport module, an IF demodulator, a digital audio engine, an analog audio engine, a digital video engine, and an analog video engine. The TVOC also includes three sets of interfaces including output interfaces, control interfaces and ancillary interfaces.

Method And System For Rejecting Single-Sided Leakage Into An Amplitude Modulated (Am) Channel

US Patent:
7558549, Jul 7, 2009
Filed:
Jul 2, 2004
Appl. No.:
10/884646
Inventors:
Hoang Huy Nhu - Irvine CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
H04B 1/68
US Classification:
455203, 455 631, 455142, 455210, 4552781, 455309, 381 11, 381 15, 348738, 348485
Abstract:
Aspects of the method and system for rejecting single sided leakage into an amplitude modulated channel may comprise an AM demodulator for demodulating a received composite broadcast signal's control channel to generate an amplitude modulated (AM) component. A PM demodulator may demodulate a received composite broadcast signal's control channel to generate a phase modulated (PM) component. At least one subtractor may subtract an AM leakage component and a PM leakage component contributed by the single sided leakage in the received composite broadcast signal's control channel. The system may comprise at least one of each of AM and PM bandpass filters and envelope detectors that filter and detect envelopes of the AM and PM components at 982. 5 Hz and 922. 5 Hz.

System And Method Of Performing Digital Multi-Channel Audio Signal Decoding

US Patent:
7912153, Mar 22, 2011
Filed:
Jun 27, 2006
Appl. No.:
11/426836
Inventors:
David Chaohua Wu - San Diego CA, US
Hoang Nhu - Irvine CA, US
Russ Lambert - Fountain Valley CA, US
Alexander G. MacInnis - Los Altos CA, US
Ronald Crochiere - San Diego CA, US
International Classification:
H04L 27/06
H04B 1/10
US Classification:
375340, 375350
Abstract:
A system and method are disclosed for performing digital multi-channel decoding of a BTSC composite audio signal. Each subsequent stage of the digital multi-channel decoding process is performed at the lowest sampling rate that yields acceptable performance for that stage. Analog-to-digital conversion of the composite audio signal is performed first to generate a composite digital audio signal. After analog-to-digital conversion, all signal processing may be performed in the digital domain. The composite digital audio signal is digitally filtered to frequency compensate for variations caused by previous stages of processing, including IF demodulation. Digital channel demodulation and filtering are performed to isolate single channels of the composite digital audio signal such as SAP, L−R, and L+R channels. SAP and L−R channels are DBX decoded resulting in corresponding decoded signals using a unique combination of digital filters that are an efficient translation of a corresponding combination of analog filters.
