Content-specific archive files can be generated concurrently with the encoding of an output stream, such as for broadcast content. Tags or triggers, such as SCTE-35 messages, can be detected in the input content stream, and those triggers used to determine actions to be taken with respect to the content stream. As an example, program start tags and end tags can be used to determine when to begin, and end, the archiving of content to an output file specific to that program content. For archives that should not include advertising, secondary content, or any non-program content, triggers such as advertising start and stop tags can be used to determine when to pause and resume recording for those archives. Once completed, these archive files can be made accessible to users, such as through a video-on-demand service or other such offering.

Dynamic archiving of streaming content

A content streaming system and methodology for facilitating the dynamic management of adaptive bitrate streaming bundles in content streaming. The dynamic management of the adaptive bitrate streaming bundles can include the utilization of an efficiency matrix that associates meta-data associated with the delivery of content streaming data with available bitrate encodings or bitrate/format combinations. The content streaming system can then dynamically manage bitrate manifests to dynamically change encoding bitrates or bitrate/format combinations offered to clients based on network conditions, client attributes, content attributes, and the like.

Optimizing adaptive bit rate streaming for content delivery

A content streaming system and methodology for facilitating the management of adaptive bitrate streaming bundles in content streaming. The management of the adaptive bitrate streaming bundles can include the utilization of an efficiency matrix that associates meta-data associated with the delivery of content streaming data with available bitrate encodings or bitrate/format combinations. The adaptive bitrate streaming bundles can be sent and managed at edge locations in the network. The content streaming system can then manage bitrate manifests to dynamically change encoding bitrates or bitrate/format combinations offered to clients based on network conditions, client attributes, content attributes, and the like.

Optimizing adaptive bit rate streaming at edge locations

A content provider might be responsible for content transmitted over a large number of channels, including premium channels that may have fixed quality settings. In order to provide the appropriate quality, the encoders for the premium channels are able to obtain the bit rates (and other capacity) needed. The total bit rate used for the premium channels can then be compared against a maximum bit rate for all channels for the provider to determine a remaining bit rate. The remaining bit rate can then be allocated, evenly or otherwise, across the various non-premium channels. Transmission components such as statmuxes used for the non-premium channels can be configured to adjust the bit rates as necessary based at least in part upon the allocation. Such an approach enables the premium channels to provide the fixed quality ensuring that the aggregate bandwidth meets the bit rate limit.

Dynamic quality adjustments for media transport

Systems and methods are described to enable a personalized content stream whose content can be dynamically altered by a user, such that multiple underlying contents can seamlessly be included within the personalized content stream. Multiple input content streams are encoded to include time-aligned splice point frames, which break inter frame dependency before and after a given splice point frame. Time-aligned segments are then generated from the encoded streams. A user may thereafter select segments of any of the input content streams to be included within a personalized content stream, and an output device may decode segments generated from different input content streams as part of the personalized content stream, without errors being introduced into the content stream due to the segments stemming from different input content streams. Thus, as user may dynamically alter the content of a personalized content stream based on their preferences.

Personalized content streams using aligned encoded content segments

A content streaming system and methodology for facilitating the management of content streaming. A video packaging and origination service receives streaming content that is organized according to content segments. Individual content segments will be encoded according to a plurality of encoding bitrates including a reference bitrate and one or more additional renditions. The one or more additional renditions include pointers to the baseline rendition.

Managing storage and transmission data size in video packaging systems

Systems and methods are described to enable replacement, in a packaged content stream, of a first encoded content stream with a second encoded content stream, without requiring decoding of the encoded content streams. A controller can receive a request to replace the first encoded content stream with the second encoded content stream at a specified location (e.g., a particular time). The controller can then instruct encoders associated with the respective content streams to insert a splice point frame into the respective content streams at the specified location, which splice point frame breaks inter frame dependency before and after the splice point frame. A packager can then replace the first encoded content stream with the second encoded content stream at the location of the splice point frame in the packaged content stream, without introducing errors into the packaged content stream as a result of broken inter frame dependency.

Output switching for encoded content streams

Quality parameters, such as encoding bitrate, can be determined for the providing of media content based at least in part upon aggregate consumption data. An unknown number of media players can obtain content at a bitrate that depends upon network conditions, and encoders can use variable bitrate encoding, such that egress bandwidth usage can vary widely over time. Aggregate consumption data can be obtained for the various client devices to project the egress costs for a particular period. If the projected resources deviate unacceptably from the target for the period, new quality setting values can be determined, such as new maximum, minimum, target bitrate, or target quality values for the various quality levels. These settings can be automatically applied or suggested to customers, who can then accept any or all of the suggestions, or choose to adjust at least some of the settings based on the suggestions or cost projections.

Egress service for media content

Instantaneous egress management service

Media content relating to an event can be obtained from multiple sources, such as multiple client devices associated with various users. The uploaded media can be associated with an event or identified as related to an event based upon location and timing information. The obtained media can be analyzed, and one or more filters applied to remove clips that do not satisfy certain selection criteria. Selected clips are ordered sequentially and synchronized by time code, and at least a primary audio track obtained from the devices is selected and synchronized with the video content. The content can be arranged per a determined layout, stitched together, and encoded into a single output file or stream. Media players can obtain and present the content, and can potentially switch the audio tracks or display individual clips from the output file.
