Abstract: PROBLEM TO BE SOLVED: To provide a data transmission system for transmitting a data signal between a server and a communications terminal over a transmission link having a variable bandwidth. SOLUTION: The data signal is a scalablely 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. COPYRIGHT: (C)2007,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To prevent encoding efficiency from being reduced when indicating a shape or expansion rate of a region in start of decoding in a decoder concerning a method for indicating size, shape and location of a region within a digital picture, encoder, decoder and the like. SOLUTION: The method for indicating size, shape and location of a region within a digital picture divided into a set of blocks is characterized in that a value for at least one size parameter which is indicative of a number of the blocks within the region of the digital picture is defined, and a value for at least one shape evolution parameter which is indicative of a selection order of the blocks in the region is selected. Then, preferably, the values for the at least one size parameter and the at least one shape evolution parameter are encoded into a bitstream of a video sequence in order to indicate size, shape and location of the region within the digital picture.

Abstract: A system and method provides a first integrity check code that can be calculated at an encoder and then sent to a decoder as a supplemental enhancement information message. The decoder can then calculate a second integrity check code over the actual received network abstraction layer units. This second integrity check code can be compared with the encoder-generated first integrity check code sent via the supplemental enhancement information message to indicate if in fact all of the transmitted NAL units from which the integrity check code was generated have been received without changes in their content. In addition, an error tracking algorithm is provided that can be run at either the encoder or the decoder in order to determine if the network abstraction layer units are correct in content at the decoder level. Therefore, pictures that are sent as just intra coded frames and pictures that are sent as just inter coded frames can both be checked for errors. Hence, error checking can be provided in those situations where the decoder fails to provide adequate information to the encoder as to what has actually been decoded.

Abstract: For enabling a time-shifted presentation of at least one received media stream, at least one media fragment is created. The at least one media fragment includes meaia data from a section of the at least one received media stream and associated media data. The media data is stored to a media data section of a file and the associated meta data is stored to a meta data section of this file. In case of a user request to start a time- shifted presentation, the file may then be parsed for retrieving media data of a respective media fragment for presentation.
