In one aspect, an example method includes (i) while a media playback device of a vehicle is playing back content received on a first channel, generating, by the media playback device, a query fingerprint using second content received on a second channel; (ii) sending, by the media playback device, the query fingerprint to a server that maintains a reference database containing a plurality of reference fingerprints; (iii) receiving, by the media playback device from the server, identifying information corresponding to a reference fingerprint of the plurality of reference fingerprints that matches the query fingerprint; and (iv) while the media playback device is playing back the first content received on the first channel, providing, by the media playback device for display, at least a portion of the identifying information.

An example apparatus to monitor media that is presented via a mobile device includes: an application monitor to determine when media presentation software is being executed by the mobile device; and a metering information collector to collect at least one of a signature or a code of the media presented by the media presentation software based on the media presentation software being executed by the mobile device.

Examples of the present disclosure relate to a device, method, and system for integrating a projection mode of a user mobile device with a terrestrial tuner. In an example, the system may be a vehicle including a head unit and a vehicle projection stack to operate in the head unit. The system may also include a terrestrial tuner communicatively coupled to the vehicle projection stack to receive a terrestrial audio signal from a terrestrial source. The system may also include an audio driver to provide an audio signal to a vehicle interior where the audio signal is from at least one of the terrestrial audio signal and an internet audio signal received at the vehicle projection stack from a user mobile device located inside the vehicle interior.

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.
