A computer-implemented method for seamlessly playing a composite media presentation, includes receiving, by a sequencer, a sequential playlist provided by a scheduler. The sequential playlist refers to a sequence of one or more streaming media content items. The sequencer receives calls from a native player application at regular intervals, and sends playback segments and seekbar update information to the native player application based on the sequential playlist in response to the calls. The native player application is configured to play the composite media presentation using at least one core player and generate a corresponding seekbar for the presentation based on the playback segments and the seekbar update information sent by the sequencer.

An electronic MIMO-OFDM carrier frequency recovery method is disclosed. The method includes receiving a wirelessly propagated time-domain signal observation, estimating a data-channel vector from a latest observation vector by correcting for a phase rotation effect based on an initial estimate or an up-to-date estimate of a phase rotation term, removing an effect associated with the data-channel vector from the latest observation vector using the estimated data-channel vector to obtain an up-to-date estimate of the phase rotation term; and repeating those prior acts iteratively to allow for production of FFT input samples that are free or nearly free of carrier frequency and phase error.
