Abstract
A method is provided for facilitating error recovery of media stream packets in an access node. The method comprises storing a plurality of data transmission units of a media stream in a buffer of an access node, receiving a request for retransmission of at least one designated data transmission unit for reception by a designated subscriber media decoder apparatus, accessing the at least one designated data transmission unit within the buffer in response to receiving the request for retransmission and transmitting the at least one designated data transmission unit from the access node for reception by the designated subscriber media decoder apparatus in response to successfully accessing the at least one designated data transmission unit.
Claims19
A method, comprising:
- storing a plurality of data transmission units of a media stream in a buffer of an access node;
- receiving a request for retransmission of at least one designated data transmission unit for reception by a designated subscriber media decoder apparatus;
- accessing said at least one designated data transmission unit within the buffer in response to receiving the request for retransmission;
- and
- transmitting said at least one designated data transmission unit from the access node for reception by the designated subscriber media decoder apparatus in response to successfully accessing said at least one designated data transmission unit.
A method, comprising:
- assessing completeness of media stream information accessible within media stream decoder apparatus;
- requesting retransmission of a required portion of said media stream information for reception by the media stream decoder apparatus in response to said assessing having determined that the required portion of said media stream information is not accessible from within the media stream decoder apparatus;
- and
- receiving the required portion of said media stream information from an access node after said requesting retransmission is performed and in response to successfully accessing the required portion of said media stream information from within a buffer of the access node.
An access node, comprising:
- at least one data processing device;
- a buffer connected to said at least one data processing device;
- memory connected to said at least one data processing device;
- and
- instructions accessible from said memory and processable by said at least one data processing device, wherein said instructions are configured for enabling said at least one data processing device to facilitate:
- storing a plurality of data transmission units of a media stream in the buffer;
- receiving a request for retransmission of at least one designated data transmission unit for reception by a designated subscriber media decoder apparatus;
- accessing said at least one designated data transmission unit within the buffer in response to receiving the request for retransmission;
- and
- transmitting said at least one designated data transmission unit for reception by the designated subscriber media decoder apparatus in response to successfully accessing said at least one designated data transmission unit.
