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. 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 play-back 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 on-screen concurrently.
