The platform is directed to various aspects of content transmission. The platform causes a viewing device to receive fragment-level metadata associated with a first fragment of content. The platform receives a request for a second fragment of the content, immediately subsequent to the first fragment of the content. The platform determines that the second fragment of the content is not stored at a content storage device at a time of receiving the request, and that the second fragment of the content is expected to be stored at the content storage device within a defined time period. Responsive to these determinations, the platform holds the received request for the defined time period. The platform determines, prior to expiration of the defined time period, that the second fragment of the content is stored at the content storage device, and transmits the second fragment of the content to the viewing device.
