  • Techniques for limiting live streaming bitrates
    Patent number: 12786262
    Abstract: In various embodiments, an adaptive bitrate ladder (ABL) application limits streaming bitrates during live events. The ABL application receives a value from an edge server included in a CDN and determines a policy based on the value. The policy includes a maximum bitrate for streaming downloadables associated with a live event. The ABL application transmits the policy to the edge server. The edge server implements the policy to prohibit a client device from requesting a first segment of a first downloadable that is associated with the live event and has a bitrate that exceeds the maximum bitrate.
