  • Patent number: 8819526
    Abstract: Provided is a method and apparatus for encoding and decoding in which block coding is applied. According to a method and apparatus for block coding encoding and decoding, a minimum quality seamless service may be provided by reliably recovering high importance data even though continuous data loss occurs in a wired and wireless transmission line. A transposed duplication calculation or a post duplication calculation may be performed with respect to the high importance data. Data of a predetermined lost time zone may be recovered by duplicated data of another time zone.

  • Patent number: 8661152
    Abstract: A method and an apparatus for reducing a deterioration of a Quality of Experience (QoE) in a multimedia service. The method includes reproducing a first multimedia stream by the multimedia device, receiving a command for reproducing a second multimedia stream during the reproducing of the first multimedia stream, and reproducing the second multimedia stream with reference to information regarding a unit image that is independently decoded from the second multimedia stream. The information regarding the unit image includes information regarding a number of unit images per unit time included in the second multimedia stream.
