Generalized Punctured Convolutional Codes with Unequal Error Protection

EURASIP Journal on Advances in Signal Processing, 2009
We conduct a code search restricted to the recently introduced class of generalized punctured convolutional codes (GPCCs) to find good unequal error protection (UEP) convolutional codes for a prescribed minimal trellis complexity.

Historical Information Aware Unequal Error Protection of Scalable HEVC/H.265 Streaming Over Free Space Optical Channels

IEEE Access, 2016
Free space optical (FSO) systems are capable of supporting high data rates between fixed points in the context of flawless video communications. Layered video coding facilitates the creation of different-resolution subset layers for variable-throughput ...

Efficient Multiple Concatenated Codes With Turbo-Like Decoding for UEP Wireless Transmission of Scalable JPEG 2000 Images

IEEE Access, 2019
Most multimedia source encoders produce scalable bit streams that are vulnerable to noisy channel effects. Unequal error protection (UEP) designs are attractive solutions for such scalable bit streams.

A novel super frame Flexible Macroblock Ordering scheme for H.265 video transmission with unequal error protection [PDF]

Serbian Journal of Electrical Engineering
One of the most popular video coding standards in use today is High Efficiency Video Coding (HEVC), also known as H.265. In this paper, a novel Flexible Macroblock Ordering (FMO) scheme known as Super frame FMO (SFMO) is proposed for HEVC video ...

Packetization schemes for forward error correction in Internet video streaming [PDF]

, 2003
In this work, our focus is on video streaming applications with relatively strict delay constraints; for such applications, forward error correction (FEC) is the preferred channel coding technique to recover from packet losses.

Dependency-aware unequal erasure protection codes [PDF]

, 2006
Classical unequal erasure protection schemes split data to be protected into classes which are encoded independently. The unequal protection scheme presented in this paper is based on an erasure code which encodes all the data together according to the ...

Adaptive sub-channel allocation based UEP for video transmission in space-time coded OFDM systems [PDF]

, 2004
In this work, we introduce the idea of adaptive sub-channel allocation based unequal error protection (ASCA-UEP) to a space-time block coded orthogonal frequency division multiplexing (STBC-OFDM) system.
