In an example, a method for delivering a multimedia data stream includes determining a frequency for generating one or more repair packets and a placement for positioning the one or more repair packets in the multimedia data stream based on a configuration parameter related to the multimedia data stream. The frequency and the placement may be determined based on a priority derived from a multimedia delivery use-case. Further, the method includes generating the one or more repair packets by network coding source packets of the multimedia data stream based on the determined frequency and the placement and transmitting the network coded multimedia data stream with the repair packets to a receiving device.

Methods, systems, and bitstream syntax are described for the entropy modeling of latent features in image and video coding using a combination of probability density functions. Using high-level syntax elements, an encoder may signal to compliant decoders the multi-distribution entropy model using: the number of one or more PDFs being used, an identifier of each PDF being used among a list of available PDFs, the number of PDF parameters in each PDF, and syntax elements indicating which PDF parameters across two or more PDFs being used are being shared.
