Abstract: Techniques are described for just-in-time variable adaptive encoding and delivery of media content. Fragments of media content are encoded at bitrates corresponding to available bandwidth of client devices. If the available bandwidth changes, the bitrate at which fragments are being encoded is adjusted to correspond with the changed bandwidth.

Abstract: Methods and apparatus are described for providing thinned manifests during a live event. As network usage of a regional internet service provider (ISP) or content delivery network (CDN) becomes unsustainable, new streaming sessions for a live event are provided a thinned manifest that does not have playback options for bitrates above a bitrate limit.

Abstract: Methods and apparatus are described for stitching independently encoded content streams together such that they appear to be part of a single streaming session.

Abstract: Methods and apparatus are described for making broadcast content available as an on-demand asset soon after all of the video fragments of the broadcast content have been made available. As the video fragments of the broadcast content are made available, they are requested and archived. When all of the fragments for the duration of the broadcast content are available (e.g., a live event ends), a VOD-style manifest is generated and the archived fragments are made available for downloading or streaming using the VOD-style manifest.

Abstract: Methods and apparatus are described for reducing subtitle information for just-after-broadcast (JAB) content. Redundant information in subtitle entries is removed so that some client devices with limited memory can handle the single subtitle file that is delivered with JAB content.
