Abstract
Systems, apparatus, articles of manufacture, and methods are disclosed to synchronize media playback at devices in a multicast environment. Disclosed is a system to synchronize media playback, the system comprising programmable circuitry, and a memory that stores executable instructions that, when executed or instantiated by the programmable circuitry, facilitate performance of operations, comprising transmitting, using a hypertext transfer protocol (HTTP), a first request in a first HTTP message to a first client device and to a second client device, receiving, from the first client device in response to the first request. a first time stamp associated with a first presentation, the first time stamp representing a first playback time within the first presentation, receiving, from the second client device in response to the first request, a second time stamp associated with a second presentation, the second time stamp representing a second playback time within the second presentation, calculating a time difference between the first time stamp and the second time stamp, determining whether the time difference satisfies a threshold, transmitting a second HTTP message to the first cli…
