Various other methods, systems, and computer-readable media are also disclosed.

Aspects of the subject disclosure may include, for example, a method, comprising: receiving, by a media processor including a processor, spherical audiovisual media content from a content delivery network; rendering, by the media processor, video for a point of view in the spherical audiovisual media content at a display device coupled to the media processor; receiving, from a remote control device coupled to the media processor, a control signal panning the point of view, resulting in a new field of view; and generating, by the media processor, audio signals from the spherical audiovisual media content corresponding to the new field of view, wherein the audio signals are adapted to audio reproduction equipment coupled to the media processor. Other embodiments are disclosed.

Real-time latency of audio/video streams is identified. Signatures of a reference audio/video stream and signatures of a test audio/video stream are buffered. A needle is constructed as a vector including a set of signatures of the reference audio/video stream. Correlations of the needle to successive vectors of sets of signatures of the test audio/video stream are computed using a correlation function that calculates relatedness of the needle vector to each of the successive vectors of the test audio/video stream. A synchronization offset is identified between the test stream and the reference stream according to a maximum correlation point of the correlations of the needle to the successive sets of signatures of the test audio/video stream. The reference audio/video stream and the test audio/video stream are aligned according to the synchronization offset.
