摘要： An apparatus comprising a controller configured to divide a section of an encoded multimedia signal into at least two segments depending on a time based decoding criteria; a generator configured to determine an error correction code for each of the at least two time segments; and a distributor configured to associate the error correction code for each of the at least two time segments with the section of the encoded multimedia signal and with a section of at least one further encoded multimedia signal.

摘要： Methods, devices, computer program products and systems for transmitting and receiving media information are disclosed. The media information is protected against errors introduce by an unreliable channel by error-protection information. The error-protection information is generated, transmitter, received and/or used in rendering based on the context of the receiver, e.g. based on a geographical location of the receiver.

摘要： A system and method for providing faster tuning into a chosen program in a time- sliced multicast and/or broadcast transmission environment. Multimedia data of the same source material but of different transmission and presentation characteristics are coded and compressed. According to various embodiments, simulcast streams of a program are time-sliced, placed maximally apart from each other in terms of transmission time, and sent over the channel.
