Abstract
Systems and methods are disclosed for generating an adaptive bitrate ladder for a content item based on the actual quality of the content item. A broadcaster determines a quality score of a content item and multiplexes a message indicating the quality score with data packets of the content item to an OTT provider. The OTT provider uses the quality score to determine an ABR ladder with a set of bitrates for the content item. The OTT provider then encodes a plurality of portions of the content item for each bitrate. The OTT provider then generates a manifest indicating a portion of a URL corresponding to each portion and transmits the manifest to a client device.
Claims12
A method comprising:
- receiving, at a quality determination system of an over-the-top (OTT) provider from a broadcaster, data packets, wherein the broadcaster was configured to:
- access a content item from a source;
- access a quality score of the content item;
- encode the content item to generate a broadcaster-encoded content item;
- multiplex a message indicating the quality score into a plurality of data packets that comprise at least a part of the broadcaster-encoded content item;
- and
- transmit the data packets to the OTT provider;
- identifying, by the quality determination system of the OTT provider, the quality score based on the message multiplexed into the plurality of data packets;
- selecting, by a backoffice of the OTT provider, a set of bitrates for the content item based on the quality score;
- encoding, by an adaptive bitrate (ABR) transcoder of the OTT provider, for each respective bitrate of the set of bitrates a respective plurality of encoded portions based on content item data from the plurality of data packets;
- generating, by a packager of the OTT provider, a manifest indicating, for each encoded portion of each respective plurality of encoded portions, at least a respective encoded portion of a uniform resource locator (URL);
- and
- transmitting, by the OTT provider, the manifest to the client device.
A system comprising:
- a quality determination system of an over-the-top (OTT) provider configured to:
- receiving, from a broadcaster, data packets, wherein the broadcaster was configured to:
- access a content item from a source;
- access a quality score of the content item;
- encode the content item to generate a broadcaster-encoded content item;
- multiplex a message indicating the quality score into a plurality of data packets that comprise at least a part of the broadcaster-encoded content item;
- and
- transmit the data packets to the OTT provider;
- and
- identify the quality score based on the message multiplexed into the plurality of data packets;
- the backoffice of the OTT provider configured to select a set of bitrates for the content item based on the quality score;
- an adaptive bitrate (ABR) transcoder of the OTT provider configured to encode for each respective bitrate of the set of bitrates a respective plurality of encoded portions based on content item data from the plurality of data packets;
- a packager of the OTT provider configured to generate a manifest indicating, for each encoded portion of each respective plurality of encoded portions, at least a respective encoded portion of a uniform resource locator (URL);
- and
- the OTT provider configured to transmit the manifest to the client device.
