Abstract: Server-side trick mode restrictions in a stream may be provided. The stream may comprise, for example, a Video on Demand (VOD) Adaptive Bitrate (ABR) stream. First, a playlist request corresponding to a stream may be received from a user device. Next, a current stream position in the stream may be determined. In response to receiving the playlist request and when the current stream position corresponds to a non-skip segment, a playlist may be created having a last chunk comprising a next chunk of the stream from the current stream position. The playlist may then be provided to the user device.

Abstract: A first manifest request may be received and, in response, a first manifest may be requested. Next, at least one interstitial content insertion source may be queried based on the first manifest and, in response to querying the interstitial content insertion source, interstitial content details may be retrieved from the at least one interstitial content insertion source. Then it may be determined that a version of interstitial content corresponding to the interstitial content details does not exist in a service provider back end at same bitrates as content corresponding to the first manifest. Next, local ingest and encoding of the interstitial content to the service provider back end may then be triggered in response to determining that the version of interstitial content corresponding to the interstitial content details does not exist in the service provider back end at the same bitrates as the content corresponding to the first manifest.
