Abstract
Systems, methods, apparatus and computer program products for providing forward error correction with low latency to live streams in networks are provided, including outputting source data at a rate less than the rate of a source stream, building a buffer, FEC decoding the source data; and outputting the packets at a rate equal to the rate of the source stream.

1-16. (canceled)
A method for providing forward error correction, comprising steps of:
- receiving source data at a first rate;
- outputting the source data at a rate less than the first rate;
- collecting the source data in a buffer;
- FEC decoding the source data, thereby generating decoded data;
- and
- outputting the decoded data at a rate equal to the first rate, either after collecting the source data in the buffer for a predetermined time duration or after collecting a predetermined amount of the source data in the buffer.
A receiver for providing forward error correction, comprising:
- a receiving unit configured to receive source data at a first rate;
- an output unit configured to output the source data at a rate less than the first rate;
- a buffer configured to collect the source data;
- an FEC decoder configured to FEC decode the source data, thereby generating decoded data;
- and
- said output unit further configured to output the decoded data at a rate equal to the first rate, either after collecting the source data in the buffer for a predetermined time duration or after collecting a predetermined amount of the source data in the buffer.
A non-transitory computer-readable medium having stored therein a computer program that, when executed by a computer processor, causes the computer processor to perform a method for providing forward error correction, wherein the method comprises steps of:
- receiving source data at a first rate;
- outputting the source data at a rate less than a first rate;
- collecting the source data in a buffer;
- FEC decoding the source data thereby generating decoded data;
- and
- outputting the decoded data at a rate equal to the first rate, either after collecting the source data in the buffer for a predetermined time duration or after collecting a predetermined amount of the source data in the buffer.
A method for providing forward error correction, comprising steps of:
- receiving source packets at a first rate;
- outputting the source packets at a rate less than the first rate;
- collecting the source packets in a buffer;
- correcting packet losses while the buffer is being built;
- and
- outputting reconstructed source packets at a rate equal to the first rate, either after collecting the source packets in the buffer for a predetermined time duration or after collecting a predetermined amount of the source packets in the buffer.
A receiver for providing forward error correction, comprising:
- a receiving unit configured to receive source packets at a first rate;
- an output unit configured to output the source packets at a rate less than the first rate;
- a buffer configured to collect the source packets;
- a correction unit configured to correct packet losses while the buffer is being built;
- and
- said output unit further configured to output reconstructed source packets at a rate equal to the first rate, either after collecting the source packets in the buffer for a predetermined time duration or after collecting a predetermined amount of the source packets in the buffer.
A non-transitory computer-readable medium having stored therein a computer program that, when executed by a computer processor, causes the computer processor to perform a method for providing forward error correction, wherein the method comprises steps of:
- receiving source packets at a first rate;
- outputting the source packets at a rate less than the first rate;
- collecting the source packets in a buffer;
- correcting packet losses while the buffer is being built;
- and
- outputting reconstructed source packets at a rate equal to the first rate, either after collecting the source packets in the buffer for a predetermined time duration or after collecting a predetermined amount of the source packets in the buffer.
A method for providing forward error correction, comprising steps of:
- receiving video data at a first frame rate;
- outputting the video data at a frame rate less than the first frame rate;
- collecting the video data in a buffer;
- FEC decoding the video data, thereby generating decoded video data;
- and
- outputting the decoded video data at a frame rate equal to the first frame rate, either after collecting the video data in the buffer for a predetermined time duration or after collecting a predetermined amount of the video data in the buffer.
A receiver for providing forward error correction, comprising:

- an FEC decoder configured to FEC decode the video data, thereby generating decoded video data;
- and
- said output unit further configured to output the decoded video data at a frame rate equal to the first frame rate, either after collecting the video data in the buffer for a predetermined time duration or after collecting a predetermined amount of the video data in the buffer.
A non-transitory computer-readable medium having stored therein a computer program that, when executed by a computer processor, causes the computer processor to perform a method for providing forward error correction, wherein the method comprises steps of:
