Forward error correction (FEC) coding is widely used in communication systems to correct transmission errors. In IEEE 802.11a/g transmitters, convolutional codes are used for FEC at the physical (PHY) layer. As is typical in wireless systems, only a limited choice of pre-specified coding rates is supported. These are implemented in hardware and thus difficult to change, and the coding rates are...
In the scalable video coding (SVC) standard, spatial scalable coding outperforms simulcast coding when programs with several display resolutions are needed. Nevertheless, it is not suitable for end devices which only need the high resolution, due to a serious performance loss on the high spatial layer compared with single layer coding. To tackle this dilemma, a selective inter−layer prediction ...
Scalable video coding provides an efficient solution to support video playback on heterogeneous devices with various channel conditions in heterogeneous networks. SHVC is the latest scalable video coding standard based on the HEVC standard. To improve enhancement layer coding efficiency, inter-layer prediction including texture and motion information generated from the base layer is used for en...
