A power-optimized joint source channel coding for scalable video streaming over wireless channel
Scalable video streaming over wireless link is a very challenging task due to the time-varying characteristics of wireless channel and limited battery resource in the handheld devices. This paper first describes a general approach for joint source channel coding (JSCC) with optimal power consumption. Then, an end-to-end power-optimized architecture for video streaming is presented. Therein the ...
متن کاملJoint Source-Channel Coding for Video Communications
The compression or coding of a signal (e.g., speech, text, image, video) has been a topic of great interest for a number of years. Numerous results and successful compression standards exist. Source compression is the enabling technology behind the multimedia revolution we are experiencing. The two primary applications for data compressing are storage and transmission. Video transmission is the...
متن کاملJoint power control and source-channel coding for video communication over wireless networks
Video communication over wireless link is a challenging task due to the time-varying characteristics of a wireless channel and limited battery resource in the handheld devices. This paper proposes a power-optimized approach for video communication, which simultaneously controls the transmission power, source rate and error protection level to minimize the total power consumption for all users. ...
متن کاملDistributed Joint Source-Channel Coding in Wireless Sensor Networks
Considering the fact that sensors are energy-limited and the wireless channel conditions in wireless sensor networks, there is an urgent need for a low-complexity coding method with high compression ratio and noise-resisted features. This paper reviews the progress made in distributed joint source-channel coding which can address this issue. The main existing deployments, from the theory to pra...
متن کاملJoint Source/Channel Coding using DCT for Video Games over Mobile Networks
Interactive computer games are increasingly demanding mobile support and video-realism. Quality of Service (QoS)-guarantee for the mobile video game applications is significantly important. An architectural framework for multimedia networks based on substreams or flows is effectively exploited for combining source and channel coding for multimedia data. But the existing frame by frame approach ...
