Abstract: A sidelink connection is created between each device of a plurality of devices. A first device connected to a content source retrieves a manifest file for the media from the content source. The first device then notifies other devices, including a second device not connected to the content source, that the manifest file is available from the first device. Based on connection metrics of each device, it is determined which of the devices has the highest quality connection to the content source. If, for example, the first device is determined to have the highest quality connection, then the first devices retrieves a segment of the media from the content source, stores the segment in a cache of the first device, and delivers the segment to other devices in response to requests for the segment received from each device.

If the segment is requested from a first device by a second device and the sidelink connection between the first device and the second device is not sufficient to transmit the first version of the segment, the first device may cause transmission of the lower quality version of the segment retrieved by a third device to the second device.
