In an embodiment, a content server has multiple queues, each of which includes records. Each record in a queue represents a frame in a logical group of frames. Each of the queues transitions between a control state, an ingestion state, and a distribution state. During the control states, records are added to the queues. During the ingestion states, the frames are copied into memory at the content server. During the distribution states, the content server sends the logical groups to a client. Each of the control state, the ingestion state, and the distribution state has a time duration equal to the amount of time needed to play the logical group.
