摘要:
An area not displayed by a first stream recorded in a disk is complemented by a second stream which is transmitted from a server through a network to a playback apparatus. A picture represented by the second stream is superimposed on a picture represented by the first stream to display a complete picture. A sound included in the second stream is also mixed with a sound included in the first stream to output a complete sound.

摘要:
A play-back device receiving data including program parts and specific parts, detecting duplicated part in which contents are repeated in the specific part included in the data and before and after the specific part. On playing back the data, when it comes to the specific part or the duplicated part it outputs an indication indicating that it is the specific part or the duplicated part on a display screen. When it receives a skip play-back or fast play-back instruction from a user, it controls to skip play back or fast play back the specific part or the duplicated part. It then becomes possible to provide a play-back device with enhanced usefulness for the user and a method for controlling the same.

摘要:
A base precursor in the form of a salt of an organic base with a carboxylic acid is disclosed. The organic base is a diacidic to tetraacidic base which is composed of two to four guanidine moieties and at least one linking group for the guanidine moities. The organic base is such a hydrophilic compound that the number of carbon atoms contained in the organic base is not more than six times the number of the guanidine moieties. The linking group is a residue of a hydrocarbon or a heterocyclic ring. The guanidine moiety corresponds to an atomic group formed by removing one or two hydrogen atoms from a compound having the following formula (I): ##STR1## where each of R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 independently is hydrogen, an alkyl group, an alkenyl group, an alkynyl group, a cycloalkyl group, an aralkyl group, an aryl group or a heterocyclic group, each of which may have one or more substituent groups, and any two of R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 may be combined together to form a five-membered or six-membered nitrogen-containing heterocyclic ring. A process for formation of an organic base from the base precursor and a light-sensitive material containing the base precursor are also disclosed.
