Systems and methods of processing closed captions for live streams are disclosed. For example, a media server may receive closed captioning data associated with a live video stream, where the closed captioning data is represented in a first format. The media server may convert the closed captioning data from the first format to a platform-independent format and convert the closed captioning data from the platform-independent format to a second format. The media server may transmit the closed captioning data in the second format to a destination device.
