5. A computing device, comprising:

one or more processors and memory configured to:

receive a first indication that a first viewer device has requested media content;

generate first manifest data representing playback options of the media content at a first plurality of quality levels selected based on characteristics of the first viewer device, each of the first plurality of quality levels being associated with one of a plurality of request formats for requesting fragments of the media content, each of the plurality of request formats corresponding to playback of the requested media content corresponding to the first indication, a first quality level of the first plurality of quality levels being associated with a first request format in the plurality of request formats, the first request format representing a fragment of the media content that is at a quality level different than the first quality level;

provide the first manifest data for playback of the media content at the first viewer device;

receive a first request from the first viewer device for a first fragment corresponding to a first segment of the media content, the first request having been generated by the first viewer device to obtain a fragment at the first quality level of the first plurality of quality levels represented in the first manifest data;

provide to the first viewer device, in accordance with the first manifest data, a second fragment corresponding to the first segment of the media content, the second fragment corresponding to a second quality level of the first plurality of quality levels represented in the first manifest data that is different than the first quality level represented in the first manifest data.

6. The computing device of claim 5 , wherein the first plurality of quality levels has a different number of quality levels than the second plurality of quality levels.

7. The computing device of claim 5 , wherein the first and second manifest data include data representing fragments corresponding to segments of a video portion of the playback of the media content, and the quality levels correspond to different bitrates corresponding to playback of the media content.

8. The computing device of claim 5 , wherein the first plurality of quality levels is based at least in part on a determination that the first viewer device is a first device type, and the second plurality of quality levels is based at least in part on a determination that the second viewer device is a second device type, the first device type and the second device type being different.

9. The computing device of claim 5 , wherein the first plurality of quality levels is based at least in part on a playback history corresponding to the first viewer device, and the second plurality of quality levels is based at least in part on a playback history corresponding to the second viewer device.

10. The computing device of claim 5 , wherein the first plurality of quality levels is based at least in part on characteristics of the first indication, and second plurality of quality levels is based at least in part on characteristics of the second indication.

11. A computer program product comprising one or more non-transitory computer-readable media having computer program instructions stored therein, the computer program instructions being configured such that, when executed by one or more computing devices, the computer program instructions cause the one or more computing devices to:

receive a first indication that a first viewer device has requested media content;

generate first manifest data representing playback options of the media content at a first plurality of quality levels selected based on characteristics of the first viewer device, each of the first plurality of quality levels being associated with one of a plurality of request formats for requesting fragments of the media content, each of the plurality of request formats corresponding to playback of the requested media content corresponding to the first indication, a first quality level of the first plurality of quality levels being associated with a first request format in the plurality of request formats, the first request format representing a fragment of the media content that is at a quality level different than the first quality level;

provide the first manifest data for playback of the media content at the first viewer device;
