摘要:
A media content monitoring system uses a rack adapted to receive multiple carrier boards to improve the system's ability to be configured to specific applications. Each carrier board contains tuner modules for receiving AM/FM broadcasts, satellite radio broadcasts, TV audio broadcasts, HD, IBOC, DAB and DRM digital radio broadcasts, etc. The tuner modules produce a USB output that is combined by a USB hub on the carrier boards into a single USB output. The carrier board outputs are in turn combined by a rack based USB hub into single USB output that is provided to a host computer. The host computer includes content identification software that automatically identifies selected media content received by the tuner modules and stores the selected content in a database. The host computer can send control codes to the tuner modules to alter their reception parameters.

A transmitting accessory couples with a portable electronic device such that audio signals or data from the device can be digitally transmitted to a remote receiver. The accessory includes an input port for receiving audio data from the portable electronic device. A digital transmitter transmits digital data corresponding to the audio signals or data from the portable electronic device to the remote digital receiver. If the audio signal is an analog signal, the accessory uses encoding circuitry to digitally encode the analog audio signal for transmission. The audio signal may be encoded into an HD radio format for reception by an HD radio receiver. The user inputs of the portable electronic device can preferably be used to control functions of the accessory and the device's display to display the selected transmission frequency or channel.

A system and method of identifying an audio track uses music identification software that produces a fingerprint or audio profile for an audio segment recorded with a portable communication device. The audio profile is transmitted from the portable communication device to a remote service provider over a communication network. The remote server receives the transmitted audio track profile and compares the profile to a stored database of audio tracks. If a matching audio track is identified by the remote server, metadata relating to the identified audio track is transmitted from the remote server to the portable communication device. The received audio track metadata is then displayed on the portable communication device.

An accessory for use with an existing portable electronic device has a housing that removably couples to a housing of the existing portable electronic device such that the accessory and portable electronic device function and can be portably carried as a single unit. A tunable FM radio receiver in the housing receives an FM broadcast signal and produces a broadcast audio output. A connector on the housing electrically connects the broadcast audio output to a corresponding connector on the device. Application software residing on the device utilizes an internet connection of the device to download digital content related to the broadcast audio output and display the digital content on a display of the device.
摘要:
A system for communicating digital data between a first and second device through audio input/output ports encodes the digital data into a series of audio frequency tones. The audio frequency tones are transferred between the devices as audio inputs. Audio decoding software residing on the devices monitors the audio inputs of the devices for audio signals representing digital data and decodes the audio signals into digital data when they are detected. The audio decoding and encoding software is preferably aftermarket software that is downloaded to the device through a digital data port and executed by the device's operating system software. The system can be used to provide a low cost accessory that can communicate digital data to a device without using the device's digital input/output port or requiring any expensive digital communication circuitry in the accessory.
摘要:
An improved accessory for an electronic device that allows the device to interface with a standard radio receiver or another electronic device using an incompatible digital transmission format. The accessory includes a digital transceiver for establishing digital communications with a first remote device having a digital transceiver. The accessory receives audio data from the device over the digital wireless channel and produces an FM broadcast output signal based upon the received digital audio data. Thus, music from a personal computer or digital music player can be listened to over a standard radio receiver. The accessory can also be configured to produce a Wi-Fi or Bluetooth formatted output such that the audio data can be transmitted to a previously incompatible radio or headphone receiver. The user inputs of the portable electronic device can preferably be used to control functions of the accessory and the device's display to display the selected transmission frequency or channel of the accessory.

A charging accessory for a portable electronic device having a device input connector includes a main charger body portion having a power supply connection to an AC wall outlet that receives an AC power supply voltage. Power conversion circuitry converts the AC power supply voltage to a DC power supply voltage. A device connector is electrically coupled to the DC power supply voltage and configured to couple the DC power supply voltage to the device input connector of the portable electronic device. The main body also has a battery pack connector that is electrically coupled to the DC power supply voltage. The battery pack connector couples to a battery pack through a charging body connector that electrically connects to the battery pack connector and receives the DC power supply voltage when the battery pack is mounted on the main charger body portion. A rechargeable battery in the battery receives the DC power supply voltage to recharge the rechargeable battery. A device connector allows the battery pack to be directly coupled to the device input connector on the portable electronic device to provide an addition portable power supply for the device.
摘要:
A carrying case for a portable electronic device such as a digital music player or mobile telephone having a digital camera includes a lens for modifying an optical input of the digital camera. The lens is positioned on the carrying case to correspond to a location of an input lens of the digital camera when the device is held within the case such that the camera can be used when the device is held by the carrying case. A plurality of lens of preferably mounted on a rotating disc so that a user can select a particular lens having a desired optical effect. Alternatively, a socket can be used to selectively mount a desired lens from a set of lenses. An illuminating LED may also be included on the case exterior to provide a flash for the camera.
摘要:
An audio system uses two frequencies to transmit a left and right audio signal to a pair of wireless earphones. Mono receivers in each of the earphones respectively receive the right or left audio signals and produce an audio output. The system includes a base that docks to the earphones such that they can be charged and configured to receive an audio output at the selected transmission frequency. The audio signal can be produced by the base or received from a portable electronic device to which the base is coupled. The base can also function as an FM transmitter for the device and utilize the device's controls and display.
摘要:
A radio accessory for a portable electronic device, such as a digital music player, includes a connector that allows the radio to use accessories designed to couple with the portable electronic device. In addition, the radio includes a pass through connector that allows the radio to couple to the portable electronic device and accessory at the same time such that signals are transferred from the accessory to the portable electronic device through the radio. The radio preferably has a power supply and audio output such that it can function as a stand alone device. The radio can be configured to receive AM, FM or satellite broadcasts. The accessory is preferably a speaker dock designed to receive the portable electronic device.
