Negotiated/dynamic error correction for streamed media

An apparatus for use in a receiving device, the apparatus comprising:

• a receiver operatively configurable to receive streamed media from a sending device;
• a transmitter operatively configurable to output requests for the streamed media;
• and
• logic operatively coupled to the receiver and the transmitter, the logic being configured to generate a request for the streamed media that specifies a requested error correction level and provide the request to the transmitter.

A computer-readable medium comprising computer-executable instructions for:

• identifying a sending device configurable to provide streamed media with dynamic error correction;
• generating a request for the streamed media that identifies a requested error correction level;
• and
• providing the request for the streamed media to the sending device.

A method for use in a sending device configured to provide streamed media to a receiving device, the method comprising:

• receiving a request for streamed media from the receiving device, the request for streamed media having a requested error correction level;
• in response, generating at least one error correction data packet associated with a span of data packets to be streamed in accordance with the requested error correction level;
• and
• outputting the span of data packets and the at least one error correction data packet.

An apparatus for use in a sending device capable of streaming media to a receiving device, the apparatus comprising:

• a receiver configurable to receive a request for streamed media from the receiving device, the request for streamed media having a requested error correction level;
• logic operatively coupled to the receiver and configured to generate at least one error correction data packet associated with a span of data packets to be streamed in accordance with the received requested error correction level;
• and
• a transmitter operatively coupled to the logic and configurable to transmit the span of data packets and the at least one error correction data packet to the receiving device.

A system comprising:

• a network;
• a first device operatively coupled to the network and configured to output a request for streamed media over the network and receive streamed media over the network, the request for streamed media comprising a requested forward error correction level;
• and
• a second device operatively coupled to the network and configured to receive the request for streamed media over the network and in response generate at least one error correction data packet associated with a span of data packets to be streamed in accordance with the received requested error correction level, and output the at least one error correction data packet and the span of data packets over the network to the first device.

A computer-readable medium having stored thereon a data structure, comprising:

• at least one parameter requesting streamed media;
• at least one parameter identifying the requested streamed media;
• and
• at least one parameter establishing a receiving device requested error correction level to be applied by a sending device when providing the requested streamed media.

A computer-readable medium having stored thereon a data structure, comprising:

• an error correction packet extended real-time transport protocol (RTP) header having:
• a first parameter identifying a number of streamed data packets within a span;
• a second parameter identifying a specified number of error correction data packets associated with the span;
• and
• a third parameter identifying a sequence number of the error correction data packet with respect to the specified number of error correction data packets associated with the span.
