Systems, methods, and media for identifying and associating user devices with media cues are provided. In some embodiments, a plurality of data streams from a plurality of endpoints is received. At least one media segment is then received from a user device. It is determined whether the at least one media segment from the user device corresponds with one of the plurality of data streams from the plurality of endpoints. In response to being unable to match the at least one media segment, a media cue is inserted into one of the plurality of data streams. In response to detecting that the media cue in that data stream is received by the user device, identification information is transmitted to the user device that associates the user device with one or more services on a communications server.

Systems for controlling a presentation of data images in a video stream, comprising: at least one processor programmed to: transmit a video bit stream representing a plurality of images to a plurality of receivers using common transmission parameters; determine that a transmission link to one of the plurality of receivers is degraded; select one of the plurality of images for transmission to the one of the plurality of receivers; select degraded-link transmission parameters for transmission of the one of the plurality of images on the degraded transmission link, wherein the degraded-link transmission parameters are different from the common transmission parameters; transmit the one of the plurality of images to the one of the plurality of receivers using the degraded-link transmission parameters; and continue to transmit the video bit stream to at least one other of the plurality of receivers using the common transmission parameters.

Systems, methods, and media for identifying and selecting data images in a video stream are provided. In accordance with some embodiments, methods for identifying and selecting data images in a video stream are provided, the methods comprising: receiving a video bit stream representing a plurality of images; identifying, using a processor programmed to do so, sets of data images in the plurality of images, wherein each of the data images provides an image representation of data and each of the data images in any of the sets of data images corresponds to a single data image; and selecting at least one best data image from the sets of data images using a processor programmed to do so.

Methods for checking available bandwidth using forward error correction are provided, the methods comprising: identifying data to be transmitted; determining an amount of forward error correction data to be sent to a receiver; creating the forward error correction data based on corresponding data in the data to be transmitted; transmitting to the receiver the forward error correction data and the corresponding data in the data to be transmitted; determining an error level in at least one of the corresponding data and the forward error correction data; and when the error level is below a value, increasing the amount of bandwidth used in a transmission to the receiver of other data in the data to be transmitted over the amount of bandwidth used in the transmission to the receiver of the corresponding data and decreasing the amount of bandwidth used for forward error correction data in the transmission of the other data.

Systems, methods, and media for identifying degraded video call links are provided. In some embodiments, systems for identifying degraded video call links are provided, the systems comprising: at least one hardware processor that: calculates network metrics and quality metrics of a video call stream received at a device through a first link and then through a second link; determines whether a network problem is present in the video call stream based on the network metrics; determines whether a quality problem is present in the video call stream based on the quality metrics; and determines that the second link is degraded if both a network problem and a quality problem are determined to be present, and determines that the first link is degraded if a quality problem is determined to be present but a network problem is not determined to be present.
