A method, reception device and host device are provided for aligning data streams at a multi-source receiver. Portions of data for a plurality of data streams are received at a reception device, the plurality of data streams carrying respective content, wherein the content of each data stream is misaligned with at least one other data stream with respect to time. The portions of data are forwarded to a host device to be stored in respective delay buffers. Indexing information is maintained for each of the delay buffers. The portions of data are forwarded to the host device along with the indexing information.

A radio includes a first tuner and a second tuner. A processor compares a first perceivable volume level of a station tuned by the first tuner to at least one second perceivable volume level of at least one background station tuned by the second tuner. The processor enables automatic volume knob changes using a pre-calibrated lookup table that associates a volume step of the volume knob with a difference between the first perceivable volume level and the second perceivable volume level.

Embodiments of methods and systems for reception improvement of FM tuners are provided. An example method according to the disclosure includes receiving one or more FM broadcast signals in a common channel (Co-C) situation and provides for receiving one or more FM broadcast signals, selecting a preferred signal and outputting said signal as an IF signal. When a Co-C situation occurs, the method calculates a correlation of the one or more signals and outputs the signal showing a larger consistency value.

A radio receiver includes: a plurality of tuners that receives a broadcast signal through separate antennas; phase shifters, an adder, and a phase diversity processing unit for adjusting and compositing a phase of an output signal of each tuner of the tuners; a demodulating unit that performs demodulation processing to an input signal; a noise component detecting unit that detects a predetermined noise component included in composited output of phase diversity; and a switching processing unit that sets the signal before the composition of the phase diversity to be an object to which the demodulating unit performs the demodulation processing when the detected noise component exceeds a threshold value, and sets the signal after the composition of the phase diversity to be the object to which the demodulating unit performs the demodulation processing when the noise component has not exceeded the threshold value.

A method of operating a single-tuner radio includes tuning into a first frequency. A pause in a first signal associated with the first frequency is detected. Tuning is switched from the first frequency to a second frequency during the pause. Fieldstrength, multipath, adjacent channel energy, frequency offset and FM modulation for the second frequency are measured. Tuning is switched from the second frequency to the first frequency. Tuning is switched from the first frequency to the second frequency dependent upon the measuring step.

A radio includes a first tuner and a second tuner. A processor compares a first perceivable volume level of a station tuned by the first tuner to at least one second perceivable volume level of at least one background station tuned by the second tuner. The processor enables automatic volume knob changes using a pre-calibrated lookup table that associates a volume step of the volume knob with a difference between the first perceivable volume level and the second perceivable volume level.

A method of performing alternate frequency switching in a radio includes tuning the radio to a primary frequency. A candidate alternate frequency is identified. It is determined whether the candidate alternate frequency is a third order inter-modulation artifact. Tuning is switched from the primary frequency to the candidate alternate frequency only if it is determined in the determining step that the candidate alternate frequency is not a third order inter-modulation artifact.

A receiver-server device that is a multi-tuner radio equipped with antenna capacity suitable for acquiring signal from multiple stations and providing remote access to that signal on a live or near-live basis via circular memory buffers accessible via the Internet is provided. Further, a smart user device is connected with the receiver-server device through the Internet as an input/output controller to select, scan and hear the available stations in live, near-live and fully time-shifted modes as well as in place-shift mode. A user may rewind or fast-forward the audio stream in a variety of increments or to pause the audio stream or return the audio stream to live monitoring. A home radio is provided for a user that can be accessed from anywhere, irrespective of the user's location, and performs in live, near-live and time-shifted modes.

Various arrangements are directed to locating a television receiver. Multiple tuners of the television receiver may be simultaneously tuned to different television distribution satellites to receive timing signals. Using these timing signals, the location of the television receiver may be determined. Based on a comparison between a stored, expected location of the television receiver and the determined location, the functionality of the television receiver may be adjusted.

An audio system includes an audio device and a control device. The control device receives a second broadcast signal for an alternative frequency associated with the first broadcast signal with receive sensitivity of specified first reference sensitivity or more than the predetermined first reference sensitivity and verifies and stores a second radio frequency for transmitting the same broadcast as a radio broadcast of the first radio frequency, receives a third broadcast signal for the alternative frequency, when the first broadcast signal with receive sensitivity less than the specified first reference sensitivity, but greater than or equal to specified reference sensitivity is received, and change the frequency of the audio device from the first radio frequency to a third radio frequency, and changes the frequency of the audio device based on the second radio frequency, when the first broadcast signal with receive sensitivity less than the specified second reference sensitivity is received.
