Mechanisms are provided to transmit media stream bursts upon recognizing that a device buffer is low or empty. In particular examples, a content server transmits 6 seconds of video in 2 seconds in order to quickly replenish a device buffer so that the device can start playback sooner. Content server buffers for particular channels can be prefilled even before any stream is requested for that channel. The content server can transmit at a higher bit rate for a short period of time or alternatively can switch to transmitting a lower quality stream for a short period of time. A media stream burst can be provided without disrupting system operation or requiring client rebuffering.
