BIT ERROR CONCEALMENT FOR AUDIO CODING SYSTEMS - …
https://www.patentsencyclopedia.com/app/20090281797
[0032]An embodiment of the present invention comprises a bit error concealment (BEC) system and method that addresses the problem of undetected bit errors in an encoded audio signal received over an audio communication link, wherein the decoding of such undetected bit errors may introduce audible distortions, such as clicks, into the decoded audio signal to be …

6.8.3 Error Concealment. Error concealment is an important component of any error robust video codec. The effectiveness of a error concealment strategy is highly dependent on the performance of the resynchronization scheme. Basically, if the resynchronization method can effectively localize the error then the error concealment problem becomes much more tractable. For low …

The system was designed without channel coding. At the receiver the statistical description is exploited to conceal the errors. The results show that a significant improvement gained in bit error...
Error-Resilient Coding and Error Concealment Strategies ...
https://www.sciencedirect.com/science/article/pii/B9780120884803500047
This chapter discusses the error-resilient coding and error-concealment strategies for audio communication. It explores some of the basic techniques that are used in concealing packet losses and applied to several kinds of codecs, including frame-independent codecs, overlapped transform codecs, and fully predictive codecs.

The current heterogeneity in networks and devices demands for a high degree of flexibility in IPTV systems for digital television. A scalable video coding scheme (in this paper we focus on H.264/AVC’s scalable video coding extension SVC) accommodates this flexibility from the coding point of view. Because the IP-based network delivery chain in IPTV systems may …
