Claims12
An apparatus configured for receiving a live adaptive bitrate stream of adaptive bitrate segments, the apparatus comprising:
- a processor;
- and
- a memory containing instructions executable by the processor whereby the apparatus is operative:
- to request a manifest file associated with the live adaptive bitrate stream;
- to receive the requested manifest file;
- and
- responsive to a determination that the received manifest file has an associated update hint, wherein the associated update hint includes an indication of when the manifest file will be updated, to request an update to the manifest file.
An apparatus configured for delivering a live adaptive bitrate stream, the apparatus comprising:
- a processor;
- and
- a memory containing instructions executable by the processor whereby the apparatus is operative:
- to receive a video stream and to generate adaptive bitrate segments comprising the live adaptive bitrate stream for delivery to a requesting device;
- to generate a manifest file associated with the live adaptive bitrate stream;
- to generate an update hint indicative of when the manifest file will be updated and to associate the generated update hint with the manifest file;
- to send the manifest file in response to a request for a manifest file from the requesting device;
- and
- to enable access by the requesting device to the associated update hint.
