16 Nov 1993TL;DR: In this article, the authors describe methods and apparatus for encoding and decoding information in broadcast or recorded segment signals using spread spectrum encoding (SSA) for audio broadcast and recorded segment.
Abstract: Methods and apparatus for encoding and decoding information in broadcast or recorded segment signals are described. In certain embodiment, an audience monitoring system encodes identification information x(w) in the audio signal portion of a broadcast or recorded segment using spread spectrum encoding (100). A personal monitoring device (200) receives an acoustically reproduced version of the broadcast or recorded signal via a microphone (230), decodes the identification information from the audio signal portion despite significant ambient noise and stores (260) this information, automatically providing a diary for the audience member which is later uploaded to a centralized facility. A separate monitoring device (700) decodes additional information from the broadcast signal, which is matched with the audience diary information at the central facility. This monitor (700) may simultaneously send data to the centralized facility using a dial-up telephone line, and receive data from the centralized facility through a signal encoded using a spread spectrum technique and modulated with a broadcast signal from a third-party.

TL;DR: In this paper, a pipelined digital data receiver for a cable TV head-end which is capable of receiving DOCSIS 1.0 or 1.1 or advanced PHY TDMA or SCDMA bursts having programmable symbol rates and programmable modulation types as well as a host of other burst parameters such at Trellis code modulation on or off, scrambling on/off, various values for Reed-Solomon T number and codeword length.
Abstract: A pipelined digital data receiver for a cable TV headend which is capable of receiving DOCSIS 1.0 or 1.1 or advanced PHY TDMA or SCDMA bursts having programmable symbol rates and programmable modulation types as well as a host of other burst parameters such at Trellis code modulation on or off, scrambling on or off, various values for Reed-Solomon T number and codeword length. The receiver has an RF section to filter and digitize incoming RF signals. It also has an input section to detect impulse noise and do match filtering and despread SCDMA bursts. A timing recovery section recovers the symbol clock and detects the start of bursts and collisions. A rotational amplifier and equalizer calculate and track gain, phase and frequency offsets and correct symbols and calculates equalization coefficients. A decoder section decodes TCM and non TCM bursts, and a Reed-Solomon decoder section reconstructs RS codewords and uses them to error correct the payload data.

TL;DR: In this article, a smart card is disclosed which receives, decodes, and stores encoded data signals comprising redeemable coupons, which are embedded within television segments and are transmitted along with the normal television segments.
Abstract: A smart card is disclosed which receives, decodes, and stores encoded data signals comprising redeemable coupons. Encoded data coupons are embedded within television segments and are transmitted along with the normal television segments. The smart card receives the luminescent signals which comprise the encoded data coupons directly from the display. The smart card decodes the data coupons. The coupon is then stored within the smart card for future use. The smart card is equipped with an LCD which enables UPC codes corresponding to each of the stored coupons to be utilized. A scanner reads the UPC codes at the coupon redemption site. Once redeemed, the coupon is erased from the memory in the smart card. Advantageously, all of the functions including receiving, decoding, and storing the data signals are performed by the smart card.

TL;DR: In this article, a system for selectively reading code symbols includes a code-symbol-capturing subsystem for acquiring information about code symbols within the CSA's field of view.
Abstract: A system for selectively reading code symbols includes a code-symbol-capturing subsystem for acquiring information about code symbols within the code-symbol-capturing subsystem's field of view. The system also includes a code-symbol-decoding processor that detects a marked region of interest within the code-symbol-capturing subsystem's field of view. After initialization, the code-symbol-decoding processor decodes only those code symbols falling within the marked region of interest.

29 Oct 2013TL;DR: In this paper, a hybrid approach to decoding barcodes is presented, which includes a primary, basic signal processor for initially decoding indicia information, and a secondary, advanced signal processor to decode information that is not decoded by the primary signal processor.
Abstract: An indicia-reading system is provided that incorporates a hybrid approach to decoding indicia such as barcodes. An indicia-capturing subsystem acquires information about indicia within the indicia-capturing subsystem's field of view. An indicia-decoding module decodes indicia information acquired by the indicia-capturing subsystem. The indicia-decoding module includes a primary, basic signal processor for initially decoding indicia information, and a secondary, advanced signal processor for decoding indicia information that is not decoded by the primary, basic signal processor.
