Abstract
A watermark in Adaptive Bitrate (ABR) content may be provided. First, a cache miss may be determined in response to receiving a request that includes an address that points to a fake media segment. Next, in response to determining the cache miss, a pull request may be sent to an origin server. The pull request may include an identifier corresponding to a client device. Then, in response to sending the pull request, a redirect response may be received from the origin server. The redirect response may include an address of a real media segment with an embedded watermark.
