Abstract: The problem of reliable transmission of correlated sources over the broadcastchannel, originally studied by Han and Costa, is revisited. An alternativecharacterization of their sufficient condition for reliable transmission isgiven, which includes results of Marton for channel coding over broadcastchannels and of Gray and Wyner for distributed source coding. A``minimalistic- coding scheme is presented, which is based on joint typicalityencoding and decoding, without requiring the use of Cover-s superpositioncoding, random hashing, and common part between two sources. The analysis ofthe coding scheme is also conceptually simple and relies on a new multivariatecovering lemma and an application of the Fourier-Motzkin eliminationprocedure.
