A server resource provides notification to subscribers in a respective network environment that the content is available for retrieval at a particular bit rate (e.g., a promotional bit rate) or particular level of quality (e.g., promotional level of quality) amongst multiple levels of quality for a limited duration of time. For example, an especially high level of quality (or bit rate) of the content may be available only for the limited duration of time. After making the especially high level of quality of content available for retrieval during a promotional period, the content may be subsequently available for retrieval only at lower levels of quality. Accordingly, one or more configurations as discussed herein include changing the ability to access content encoded at different levels of quality over time.
