In response to determining that the at least one media item has been improperly scheduled during the blackout period, the media playout system transmits, to the media scheduling system, a message requesting a replacement media item to replace the at least one media item that has been improperly scheduled during the blackout period. | 2020-04-30 |
20200136735 | SYSTEMS AND METHODS FOR CONTROLLING HOSPITALITY DISTRIBUTION NETWORKS - A system includes a host device to provide a content signal, an end device to receive the content signal, and a branch of amplifiers connected between the host device and the end device to carry the content signal from the host device to the end device. The host device may receive a first signal from the branch of amplifiers connected to the end device, and extract, from the first signal, first characteristics of the content signal measured at one or more points in the branch of amplifiers. The host device may compare the first characteristics of the content signal to second characteristics. The host device may determine, based on the comparison, adjustments for one or more settings of a first amplifier of the amplifiers, and send a second signal to the branch of amplifiers to communicate the adjustments for the one or more settings to the first amplifier. | 2020-04-30 |

20200136737 | TIME SYNCHRONIZATION METHOD AND DEVICE - A time synchronization method includes receiving, by a receive-end device, a first timestamp and a first header signal sent by a transmit-end device, where the first timestamp indicates a first moment at which a first channel medium conversion module sends the first header signal, and a second moment at which the receive-end device receives the first header signal. The method further includes sending a second header signal to the transmit-end device, where a third moment at which the receive-end device sends the second header signal. The method further includes receiving a fourth timestamp sent by the transmit-end device, where the fourth timestamp indicates a fourth moment at which the transmit-end device receives the second header signal. The method further includes synchronizing time with the transmit-end device based on the first moment, the second moment, the third moment, and the fourth moment. | 2020-04-30 |
