Abstract: In one embodiment, a method includes receiving an access request for a video service from a client device, authorizing the client device to access the video service when the client device is initiating connection to the video service via a home Internet access point in a home associated with an authorized account for the video service, determining a time restriction for access to at least part of the video service when the client device is initiating connection to the video service via a non-home Internet access point located outside the home, a duration of the time restriction being dependent upon a usage behavior of the client device, and authorizing the client device to access the at least part of the video service subject to the time restriction when the client device is initiating connection to the video service via the non-home Internet access point.

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.
