Abstract
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.
Claims20
A method comprising:
- receiving a live video stream and first closed captioning data associated with the live video stream at a computing device, wherein the first closed captioning data is represented in a first format;
- loading a first converter that is compatible with the first format to convert the first closed captioning data from the first format to a platform-independent format and to convert the first closed captioning data from the platform-independent format to a second format;
- transmitting the first closed captioning data in the second format to a first destination device;
- receiving second closed captioning data associated with the live video stream, wherein the second closed captioning data is represented in a third format;
- loading a second converter that is compatible with the third format to convert the second closed captioning data from the third format to the platform-independent format and to convert the second closed captioning data from the platform-independent format to a fourth format;
- and
- transmitting the second closed captioning data in the fourth format to a second destination device.

An apparatus comprising:
- a processor;
- and
- a memory storing instructions that, when executed by the processor, cause the processor to perform operations comprising:
- receiving first closed captioning data associated with a live video stream, wherein the first closed captioning data is represented in a first format;
- loading a first converter that is compatible with the first format to convert the first closed captioning data from the first format to a platform-independent format and to convert the first closed captioning data from the platform-independent format to a second format;
- transmitting the first closed captioning data in the second format to a first destination device;
- receiving second closed captioning data associated with the live video stream, wherein the second closed captioning data is represented in a third format;
- loading a second converter that is compatible with the third format to convert the second closed captioning data from the third format to the platform-independent format and to convert the second closed captioning data from the platform-independent format to a fourth format;
- and
- transmitting the second closed captioning data in the fourth format to a second destination device.

A computer-readable storage device comprising instructions that, when executed by a computer, cause the computer to:
- receive a live video stream and first closed captioning data associated with the live video stream, wherein the first closed captioning data is represented in a first format;
- load a first converter that is compatible with the first format to convert the first closed captioning data from the first format to a platform-independent format and from the platform-independent format to a second format;
- transmit the first closed captioning data in the second format to a first destination device;
- receive second closed captioning data associated with the live video stream, wherein the second closed captioning data is represented in a third format;
- load a second converter that is compatible with the third format to convert the second closed captioning data from the third format to the platform-independent format and to convert the second closed captioning data from the platform-independent format to a fourth format;
- and
- transmit the second closed captioning data in the fourth format to a second destination device.
