“…As decoder is very sensitive to the correctness of received encode data [17], it is very necessary to guarantee the reliability of transmission, reliable transmission system usually is in closed-cycle mode with RTCP feedback. The transmission path is comprised of sender, data processing and receiver as Fig.3 shows.…”

-In real world the network environment is varied and the network resource is limited. How to supply real-time and reliable transmission service with less network resource under the explosive transmission scale becomes a hot spot, this paper proposed a novel transmission scheme which supports improved hierarchical feedback architecture, under this architecture the normal group and each emergent node are treated with independent transmission strategy, and under varied network environment each strategy can selforganize transmission structure and self-adjust transmission parameters to adapt different transmission conditions, this scheme also applies partial FEC base on Bayes learning to save bandwidth. Approach was tested on MG3500 embedded platform; experiments showed this scheme can decrease approximate 60% of original error rate on average and save about half network bandwidth compared to original FEC method error.

“…[5,6], pixel differences between two neighboring lines are used to detect transmission errors in pulse code modulation (PCM) and differential PCM (DPCM) coded images. Mitchell and Tabatabai [7] proposed a method which can detect the damage to a single DCT coefficient. However, this method is based on the framework of DCT and fixed-length codes (FLC).…”

This paper proposes a method of error detection based on macroblock (MB) types for video transmission. For decoded inter MBs, the absolute values of received residues are accumulated. At the same time, the intra textural complexity of the current MB is estimated by that of the motion compensated reference block. We compare the inter residue with the intra textural complexity. If the inter residue is larger than the intra textural complexity by a predefined threshold, the MB is considered to be erroneous and errors are concealed. For decoded intra MBs, the connective smoothness of the current MB with neighboring MBs is tested to find erroneous MBs. Simulation results show that the new method can remove those seriously-corrupted MBs efficiently. Combined with error concealment, the new method improves the recovered quality at the decoder by about 0.5-1 dB.

Die effiziente und wirtschaftliche Speicherung von Wärmeenergie steht in engem Zusammenhang mit der Nutzung von Solarenergie. Es wurden mit dem Latentwärmespeichermaterial LC‐58 gefüllte Versuchsspeicher verschiedener Größen entwickelt, die ein neues innovatives System zur Speicherung solarthermischer Energie darstellen. Zur Abdichtung gegen Wasser wurde das korrosive LC‐58 makroverkapselt.
