An information processing apparatus includes a selecting unit for selecting extraction information concerning contents to be extracted from among a plurality of contents organized in time sequence, the extraction information prepared on a per content basis for the contents to be extracted and including a feature contained in the content to be extracted, and an extraction range that is represented with respect to the position of the feature, a detecting unit for detecting, from the contents, the same feature as the feature contained in the extraction information selected by the selecting unit, and an extracting unit for extracting a predetermined content in accordance with the extraction range contained in the extraction information selected by the selecting unit if the detecting unit detects the same feature as the feature contained in the extraction information.

Apparatus, method, and computer program for processing information

An information processing apparatus includes a selector for selecting removal information concerning contents to be removed, the removal information prepared on a per content basis for the contents to be removed and including a value uniquely determined from data within a data range of whole or part of a content to be removed, a first range that is the data range, and a second range that is a removal range represented by the position of the first range, a detector for detecting a range at a predetermined position within the whole content, having the same range as the first range contained in the removal information selected by the selector and the same value as the value uniquely determined and contained in the removal information, and a remover for removing a predetermined content based on the second range contained in the removal information selected by the selector if the detector detects the range at the predetermined position.

A CPU controls the storage of isochronous packets into a main memory. The CPU inserts a nullpacket, which will be ignored by a reception apparatus, into isochronous packets so that the isochronous packets have the same size. A 1394 DMA controller controls the transmission of stored isochronous packets, which have the same size due to the inserted nullpacket, over a 1394 bus.
