Abstract: In one example, a computing system comprises processing circuitry that executes instructions to determine whether a media content item is eligible for identification of key moments, retrieve a plurality of reactions associated with the media content item, wherein each reaction comprises a reaction timestamp that corresponds to a time at which a reaction was received and a graphical icon that corresponds to one of the reactions, group the reactions based on the reaction timestamp and the selected graphical icon, identify a plurality of key moments within the media content item based on the groupings, wherein each of the key moments is associated with a representative graphical icon that corresponds to an aggregated viewer reaction, and cause an indication of the media content item to be presented in a user interface while presenting the aggregated viewer reaction at each time window associated with each of the key moments.

Abstract: Methods, systems, and media for presenting media content items with aggregated timed reactions are provided.

Abstract: An audio amplifier employs an idle mode to reduce power consumption and improve efficiency of the amplifier. The audio amplifier comprises a modulator configured to receive an analog input signal. The modulator is operable to convert the analog input signal to differential first and second quantized signals, each having a common mode duty cycle. The modulator causes the common mode duty cycle of each of the first and second quantized signals to be shifted when the level of the analog input signal is below a threshold level so that the common mode duty cycle is one of greater than or less than fifty percent (50%). The amplifier further includes a power stage that receives the first and second quantized signals and generates corresponding first and second output signals configured to drive a load, wherein the first and second output signals switched between a supply voltage and a second voltage based on the respective first and second quantized signals.
