Abstract: Videos may be loaded to an electronic device at any of a plurality of bitrates, each bitrate corresponding to a certain video quality level. The bitrate selected may be based on, for example, bandwidth capabilities and/or video quality standards. However, bandwidth capabilities may be taxed or exceeded if multiple videos are loaded simultaneously to the electronic device. Examples of the disclosure can be used to manage bandwidth, adjust bitrates, and/or selectively load video and audio in accordance with bandwidth capabilities to provide uninterrupted video playback at a relatively high quality. Further, video players may be allocated in memory and re-used as a user scrolls and switches through a number of videos playing onscreen concurrently.

However, bandwidth capabilities may be taxed or exceeded if multiple videos are loaded simultaneously to the electronic device.

Abstract: Techniques are disclosed for measuring propagation delay of a media distribution system based on content output by rendering devices. An output from an output device of the media distribution system may be captured and a token may be detected from the captured content. A timecode may be derived from the detected token. The system's propagation delay may be determined from the derived timecode and may provide a basis to analyze system delays and other processing artifacts. In this manner, propagation artifacts may be estimated between multiple rendering devices that lack controls to synchronize their operation.
