Methods and systems are described for generating content identification tiles, such as manifest files, for ensuring content and advertising continuity when changes occur during playback. A user device can request content at a particular bitrate, and a first manifest file comprising references to the content and selected associated content such as advertisements can be created in response to the request. While one of the advertisements is being displayed, the user device can request a change, such as for a different bitrate. A computing device, such as a manifest server can access the first manifest file to determine the content and the associated content, such the advertisements, that were intended for the user. The manifest server can then create a second manifest file in response to the request, where second manifest file can be created with the associated content, for example, the advertisements in the first manifest file.
