Abstract
Streaming media at an adaptive bitrate streaming media player. Tracking a bitrate history of the player. Determining a startup bitrate from the bitrate history. Streaming at the determined bitrate. Tracking a bitrate history of the player can include storing tracked bitrates in a cookie accessible by the player; and determining a startup bitrate can include determining a startup bitrate from the cookie. Determining a startup bitrate can include determining an average tracked bitrate over the last N tracked bitrates. The average tracked bitrate can be weighted toward more recent tracked bitrates. Determining a startup bitrate can include determining a maximum startup bitrate. The bitrate history can include the maximum bitrate of the player over the last X sessions; and the maximum startup bitrate can be the lowest maximum bitrate over the last X sessions. The maximum startup bitrate can be the mode among maximum bitrates over the last X sessions.
