Example techniques relate to cloud queue tombstones. An example implementation may involve a computing system receiving instructions to remove a particular media item from a playback queue. Based on the instructions, the computing system removes the particular media item from the playback queue and adds, to the playback queue, a tombstone indicator indicating that the particular media item has been removed from the playback queue. The computing system receives, from the media playback system, a request for a window of one or more media items from the playback queue. Based on the request, the computing system sends, to the media playback system, data representing a particular window of media items from the playback queue, wherein the particular window includes the tombstone indicator. The computing system detects a given tombstone removal trigger from among multiple tombstone removal triggers and based on the detecting, removes the tombstone indicator from the playback queue.

Methods, apparatus, systems and articles of manufacture to monitor a media presentation are disclosed. An example method includes in response to receipt of a media identifier, extracting, by executing an instruction with a processor, a timestamp from the received media identifier. A time of receipt of the media identifier is determined. A difference between the time of receipt of the media identifier and the timestamp from the received media identifier is determined. A time shifted viewing code is calculated based on the difference The time shifted viewing code is transmitted to a media monitor that transmitted the media identifier, the time shifted viewing code to be reported when the media monitor reports monitoring information.

Methods and apparatus to model on/off states of media presentation devices based on return path data are disclosed. An apparatus includes a memory and processor circuitry to execute instructions stored in the memory to: generate a first probability distribution indicative of actual durations of panel tuning segments, the panel tuning segments corresponding to time periods during which panelists were exposed to first media; generate a second probability distribution indicative of modelled durations of modelled tuning segments, the modelled tuning segments corresponding to modified lengths of the panel tuning segments; and estimate a set-on time for a media set associated with an RPD device based on RPD tuning information and the first and second probability distributions, the RPD tuning information reported from the RPD device, the RPD tuning information indicative of a reported RPD tuning segment during which the RPD device was accessing second media.

Systems, methods, and computer-readable media for porting locally processed media data with low latency to a remote client device via various wireless links are provided. In one example embodiment, a transceiver module may include a local network interface and a controller that may receive a client control signal from a client device over a wireless local area network via the local network interface, transmit a media control signal based on the client control signal to a media device, receive media data based on the media control signal from the media device, and transmit to the client device over the wireless local area network via the local network interface client data based on the media data and a low-latency compression technique. The receipt of the media data and transmission of the client data may be accomplished with substantially no detectable latency. Additional embodiments are also provided.

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.

Methods and system for providing content are disclosed. One method can comprise receiving a request for data at a first time, wherein the data comprises a first time duration, determining a buffer size based upon the first time duration, and determining a playback window based upon the determined buffer size and the first time. The method can also comprise synchronizing presentation of content on a plurality of devices.

Advertisements in broadcast television programming are digitally replaced with different ads prior to viewing. Replacement can occur in time and/or place shifted content, and can be used to promote a particular advertisement that the viewer has not yet seen, thereby improving the reach of the ad without oversaturation. Data reporting by the playback devices is collected in a database of viewed ads. The information in the database can be used to refresh previously-viewed ads, to increase saturation of particular ads, to replace previously-broadcast but no longer relevant ads, or for other purposes as desired.

Video playback quality detection methods, systems, and apparatuses are described. The method can include obtaining a first video data packet of a target video from a bearer network and obtaining a data byte quantity of first video data included in the first video data packet. The method may also include determining a buffer byte quantity stored in a video quality detection buffer. Furthermore, the method can include obtaining video frame data rate information corresponding to the target video and reducing the buffer byte quantity stored in the video quality detection buffer based on a video frame rate of the target video and the video frame data rate information of the target video. The method may further include determining a playback status of playing the target video on a video player, and determining video playback quality of the target video based on the playback status. According to the embodiments of the present invention, user experience and accuracy of the video playback quality detection method can be improved.
