Abstract: A data transmission system (10) is provided for transmitting a data signal between a server (12, 14, 16, 18) and a communications terminal (20, 22) over a transmission link having a variable bandwidth. The data signal is a scalable compressed multimedia clip comprising a sequence of images. Each image has a base layer and a number of enhancement layers. To cope with variability in the bandwidth, the sequence is re-ordered so that the base layers have greater safety times than the enhancement layers. This allows all of the base layers to arrive in time to be played at the expense of the enhancement layers.

Abstract: There is provided a method comprising encoding an uncompressed constituent frame into a first encoded picture, said encoding also resulting into a reconstructed first picture and said constituent frame having an effective picture area within the first reconstructed picture, performing either of the following as a part of said encoding: inserting at least one sample value outside the effective picture area to form a boundary extension for the constituent frame in the reconstructed first picture; or saturating or wrapping oversample locations outside the effective picture area to be within the effective picture area. There is also provided a method comprising receiving an encoded picture, decoding the encoded picture to form a reconstructed constituent frame of the picture having an effective picture area;and performing either of the following: filling an area outside the effective picture area to produce a padded reference picture, wherein the filled area forms a boundary extension; or determining that when referring to sample locations outside the effective picture area in decoding, said sample locations are saturated or wrapped over to be within the effective picture area.
