Cross layer coding for satellite mobile TV broadcast method and apparatus

摘要

Methods and apparatus providing error protection in multicast-broadcast service by encoding multimedia content according to a first protocol to provide a plurality of distinct video streams, coding each of the distinct video streams using respective coding protocols, wherein each coding protocol has associated with it corresponding descriptors and coefficients, and multiplexing the coded video streams toward a wireless network.

主权项

1. A method, comprising:
encoding multimedia content according to a first protocol; disassembling the encoded multimedia content to provide a plurality of distinct video streams comprising descriptors and coefficients; coding each of the plurality of distinct video streams using a respective one of a plurality of coding protocols which are distinct from the first protocol; and multiplexing the coded video streams for transmission toward a user equipment (UE) via a wireless network, each of said multiplexed coded video streams being configured for UE decoding using a corresponding decoding protocol adapted to minimize long shadowing and long fading effects by using error detection and correction for reconstructing the multimedia content.
