Patent ID: 7653055

Claim:
A method for providing media content, comprising: identifying, in an original packet stream comprising a plurality of data packets conveying media content, a data packet for which an associated importance level satisfies an importance condition, wherein the importance level of the data packet is determined using a frame type of a frame being transported by the data packet, wherein the importance level of the data packet is determined using at least one header parameter of the data packet, wherein the at least one header parameter comprises one of: a value of a random access point (RAP) flag field where the data packet includes an MPEG frame; or a value of a network abstraction layer (NAL) reference indicator (NRI) field where the data packet includes an H.264 frame; duplicating the identified data packet having an importance level satisfying an importance condition; inserting the duplicate data packet within the original packet stream to form thereby a modified packet stream, wherein the duplicate data packet is inserted within the original packet stream within an insertion window determined according to a position of the identified data packet within the original packet stream; and transmitting the modified packet stream toward a wireless terminal adapted for presenting the conveyed media content.
