According to some embodiments, a method includes selecting a length for an advanced television system committee (ATSC) 3.0 frame for transmission by a single frequency network (SFN) transmitter and aligning the SFN transmitter with a global positioning system (GPS) epoch. The method further includes storing geographical coordinates of the SFN transmitter and a corresponding SFN transmitter identification (TX ID) in a database. The method also includes encoding the SFN TX ID in a non-coherent symbol of a plurality of positioning navigation timing (PNT) symbols comprising a plurality of coherent symbols and the non-coherent symbol with orthogonal frequency-division multiplexing (OFDM) numerology to support positioning. The method further includes prepending the plurality of PNT symbols to the ATSC 3.0 frame to generate a modified ATSC 3.0 frame and transmitting the modified ATSC 3.0 using a SFN transmitter antenna of the SFN transmitter.

Techniques are described herein for optimizing the presentation of content through obtaining viewership metrics, generating multiple renditions of presentations of content, and selecting optimized renditions of content. One aspect includes associating a request for viewership metrics with a presentation of content, publishing the presentation of content, and receiving information of the viewership metrics associated with the presentation. Another aspect includes copying a presentation of a content item, creating a second presentation of the content item for publishing over one or more channels, and linking the presentation of the content item to the second presentation of the content item, such that a change to one propagates to the other of the presentation of the content item or the second presentation of the content item. In yet another aspect, a content rendition may be selected for presentation based on performance of the rendition out of multiple renditions in an auction.

Systems, devices and methods are described herein for segmentation of content, and more specifically for segmentation of content in a content management system. In one aspect, a method may include receiving content associated with speech, text, or closed captioning data. The speech, the text, or the closed captioning data may be analyzed to derive at least one of a topic, subject, or event for at least a portion of the content. The content may be divided into two or more content segments based on the analyzing. At least one of the topic, the subject, or the event may be associated with at least one of the two or more content segments based on the analyzing. At least one of the two or more content segments may then be published such that each of the two or more content segments is individually accessible.

The ATSC 3.0 physical layer broadcast standard is extended with new OFDM numerology, L1 signaling and frame structure aligned with 5G. This is done to enable improved broadcast mobility and convergence 5G release 16 as a Non-3GPP access network. The 5G core network and Broadcast core network interwork over defined interfaces to enable convergence layer 3. This enables improvements of broadcast physical layer for physics of broadcast. The 5G unicast physical layer is enhanced for physics of unicast, and then both are converged at layer 3. This is novel and has many benefits compared to the legacy LTE broadcast method (e.g., Evolved Multimedia Broadcast Multicast Services (eMBMS)), which combines both broadcast and unicast into a single shared LTE frame at layer 1. The eMBMS method is then improved for dominate unicast mode in shared L1 frame. The result is the broadcast performance and efficiency in eMBMS are less than optimal.

Systems, methods, and devices are described herein for placing secondary content into a break of unknown duration in a stream of primary content. In one aspect the described techniques may include receiving information indicative of a break in streaming of the primary content, such as metadata data that is inserted into the stream of primary content, for example, on a client device. A duration of the stream of the primary content may be obtained. Secondary content may be played, for example during a break in the streaming of the primary content. Upon detecting that the duration of the stream of the primary content has increased to a second duration, for example, in response to the client device receiving additional primary content, the primary content may be streamed.

Systems, methods, and devices are described herein for placing secondary content into a break of unknown duration in a stream of primary content. In one aspect, the described techniques may include streaming a segment of primary content, for example, by a reduce capability client device, such as a mobile device or tablet. The device may receive information indicative of a break in the streaming of the primary content. The device may play secondary content based on receiving the information indicative of the break. The device may determine when a next segment of the primary content is available, and begin streaming the next segment of the primary content upon detecting that the second segment of the primary content is available.

Systems, devices, and methods are described herein for distributing syndicated content or content with one or more distribution restrictions. In one aspect, a method may include assigning a unique ID to a plurality of content items, where the unique ID of at least one of the content items is associated with one or more property distribution restrictions. The method may further include streaming in a video stream the content items to at least two properties and monitoring the unique IDs of the plurality of content items streamed in the video stream to detect least one content item associated with the one or more property distribution restrictions. The distribution of the least one content item associated with the one or more property distribution restrictions may be blocked from the one or more properties concurrently with streaming the video stream, based on the one or more property distribution restrictions.
