Systems and methods of the present disclosure provide for dynamic delay equalization of related media signals in a media transport system. Methods include receiving a plurality of related media signals, transporting the related media signals along different media paths, calculating uncorrected propagation delays for the media paths, and delaying each of the related media signals by an amount related to the difference between the longest propagation delay (of the uncorrected propagation delays) and the uncorrected propagation delay of the related media signal/media path. Calculating the uncorrected propagation delays and delaying the related media signals may be performed in response to a change to the propagation delay of at least one of the related media signals/media paths. Additionally or alternatively, calculating the uncorrected propagation delays and delaying the related media signals may be performed while transporting the related media signals.

A system clock reference is transmitted to user devices (1, 2, 3) over a short range communication channel (40) and used to calculated a clock offset. The clock offset is stored together with a user identifier in a server memory (15), from which the clock offset can be retrieved when receiving the user identifier together with a video stream (21, 22, 23) of video frames (31, 32, 33) tagged with respective timestamps. The timestamps are converted into capture times according to a system clock (17) using the retrieved clock offsets. Video streams (21, 22, 23) from multiple user devices (1, 2, 3) thereby have video frames timestamped using a same clock reference and can be time aligned.

Disclosed herein is a reception apparatus including: a reception block configured to receive broadcast content broadcast via a broadcasting network; an acquisition block configured to acquire inserted content that is inserted in the broadcast content during the reception thereof; an output block configured to output at least one of the broadcast content and the inserted content; a switch block configured to switch between the broadcast content and the inserted content outputted from the output block; and a buffer configured to sequentially store data of the received broadcast content when the broadcast content is switched to the inserted content; wherein, if the inserted content is switched to the broadcast content, the output block outputs the broadcast content from the buffer while the inserted content is outputted.

Concepts and technologies disclosed herein are directed to audio and video synchronization. According to one aspect disclosed herein, an audio-video (“AV”) synchronization system can simultaneously capture samples of a pre-encode media stream and a post-encode media stream. The pre-encode media stream can include AV content prior to being encoded. The post-encode media stream can include the AV content after being encoded. The AV synchronization system can align a pre-encode video component of the pre-encode media stream with a post-encode video component and can determine a video offset therebetween. The AV synchronization system can align a pre-encode audio component of the pre-encode media stream with a post-encode audio component of the post-encode media stream and can determine an audio offset therebetween. The AV synchronization system can then compare the video offset and the audio offset to determine if the post-encode media stream is synchronized with the pre-encode media stream.
