This paper investigates the design and analysis of data synchronization codes whose decoders have the property that, in addition to reestablishing correct decoding after encoded data is lost or afflicted with errors, they produce the original time index of each decoded data symbol modulo some integer T . The motivation for such data synchronization with timing is that in many situations where data must be encoded, it is not sufficient for the decoder to present a sequence of correct data symbols. Instead, the user also needs to know the position in the original source sequence of the symbols being presented. With this goal in mind, periodic prefixsynchronized (PPS) codes are introduced and analyzed on the basis of their synchronization delay D, rate R, and timing span T . Introduced are two specific PPS designs called natural marker and cascaded codes. A principal result is that when coding binary data with rate R, the largest possible timing span attainable with PPS codes...

In its original formulation, multiple description (MD) coding is a multiuser lossy source coding problem, in which three decoders get to observe encodings of a single source generated by two senders.

In its original formulation, multiple description (MD) coding is a multiuser lossy source coding problem, in which three decoders get to observe encodings of a single source generated by two senders. In general, the rate delivered to each of the decoders is not the same, and based on this it has been argued that MD codes would be suitable for use as joint source/channel codes in a standard pointtopoint problem: lowrate decoders would be used when there is loss of data, and highrate decoders would be used when more data is available at the receiver.
