Web14 de nov. de 2013 · Compressed video streams transmitted over error-prone environments are usually corrupted by transmission errors. Error-concealment techniques can be used to recover the lost information. In this paper, a hybrid model is proposed to improve the error-concealment performance. The model combines two hierarchical B-picture coding … Web21 de mar. de 2016 · I am using trying to setup an arbitrary GOP structure (a GOP structure other than hierarchical B or IPPP...) in HM-16.3. I fiddled around with the configuration file setting up the GOP pattern. However, I do not know how I can force the encoder to choose a particular reference frame from a list of reference frames in the reference picture set.
