Abstract: A system and method provide an enhanced listening experience for a user of a radio receiver or other device that receives broadcast or streamed content having a plurality of program channels. The method and system buffer designated channels at the receiver and, when switching among channels, play back the buffered designated channels during reception from a selected point therein depending on the channel or other criteria. When switching to a different channel during reception, a user is able to hear content in a buffered program channel with music from the start of a song, for example, whereas content in a channel with news, talk radio, or live sports is played back from live reception, even though the content segments are transmitted at different start times relative to their selected times for playback following a channel change. User controls allow navigation among buffered designated channels during reception.

Abstract: Disclosed are various embodiments providing selecting various schemes for combining antenna signals for synchronization. For example, processing circuitry determines a first weight for a first antenna based on a signal strength metric of the first antenna and a second weight for a second antenna based on a signal strength metric of the second antenna. The processing circuitry receives a synchronization signal via the first antenna and the second antenna. Then the processing circuitry may weight the synchronization signal received via the first antenna according to the first weight to generate a first weighted synchronization signal and weight the synchronization signal received via the second antenna according to the second weight to generate a second weighted synchronization signal. The processing circuitry further combines the first weighted synchronization signal and the second weighted synchronization signal to generate a combined synchronization signal.
