Systems and methods for adaptively adjusting the spin rate of a destabilizer buffer on a remote device in a distributed access architecture. The spin rate can be adjusted based on measurements of the buffer's fullness state taken over time. These measurements can be used to calculate a frequency offset value between the rate at which data leaves the buffer and the rate at which data enters the buffer, and / or to calculate the buffer's current working depth. Adaptive spin rate adjustments can be based on the frequency offset value and / or the current working depth.

A content distributor in a content distribution system may be configured to encode each frame of a content asset individually and separately from a plurality of other frames of the content asset. Each frame of the content asset may be encoded to a plurality of pixel resolutions and may be transmitted using an Internet Protocol (IP) network such that the frame is available for playback by at least one user device. Each frame of the content asset may be placed in one or more buffers where it may be requested by a user device for playback through a content delivery network. The content distributor may be configured to generate a manifest that contains a list of specific network locations (e.g., URL's) for each pixel resolution of the frame.

In some embodiments, a method receives a data structure for an auto decision process for predicting a value for a decision feature of a plurality of features. The data structure is generated using a decision aware splitting process that splits a node in the data structure using the decision feature and a metric-based process that splits other nodes of the data structure by evaluating features in the plurality of features using a metric. Feature values are determined for a combination of features for a playback session. The method evaluates the data structure using the combination of features to determine a plurality of prediction values for a plurality of feature values of the decision feature. The prediction values are used to generate a decision for the playback session by selecting a feature value in the plurality of feature values based on the plurality of prediction values.
