Abstract: A method is provided in one example and includes receiving first synchronization information associated with a first encapsulated output, receiving second synchronization information associated with a second encapsulated output, and determining whether the first encapsulated output and the second encapsulated output are in synchronization based upon the first synchronization information and the second synchronization information. The method may further include, when the first encapsulated output and the second encapsulated output are determined to out of synchronization, generating corrected synchronization information, and sending the corrected synchronization information to an encapsulator generating at least one of the first encapsulated output and the second encapsulated output.

Abstract: A method is provided in certain example embodiments and may include evaluating a first video stream being encoded by a first encoding element, where the first video stream is provided at a first bit rate. The method may also include evaluating a second video stream being encoded by a second encoding element, where the second video stream is provided at a second bit rate. The method may further include providing an output that is reflective of a time synchronization and a frame alignment for a plurality of frames within the first video stream and the second video stream.

Abstract: A method is provided in one example and includes receiving first synchronization information associated with a first encapsulated output, receiving second synchronization information associated with a second encapsulated output, and determining whether the first encapsulated output and the second encapsulated output are in synchronization based upon the first synchronization information and the second synchronization information. The method may further include, when the first encapsulated output and the second encapsulated output are determined to out of synchronization, generating corrected synchronization information, and sending the corrected synchronization information to an encapsulator generating at least one of the first encapsulated output and the second encapsulated output.
