摘要： By reducing the number of seek operations in an operation to play back a signal from a recording medium, the amount of data temporarily stored in a read buffer memory employed in a signal recording/playback apparatus is large enough to be output as a playback signal during a seek operation, allowing a continuous playback operation to be carried out. In order to reduce the number of seek operations, a signal is always recorded onto the recording medium in continuous free areas each having a size equal to or larger than a predetermined recording/playback time length which is typically set at 1 minute. If it is necessary to insert an additional signal having a length smaller than the predetermined recording/playback time length into a point of insertion in an area already occupied by an existing signal, a continuous free area with a size equal to or larger than the predetermined recording/playback time length is newly allocated to the additional signal. The additional signal is then recorded in the free area instead of being inserted into the point of insertion. Since the free area is larger in size than the length of the additional signal, the rest of the free area is filled up with a portion of the existing signal adjacent to the point of insertion.

摘要： A video signal recording/reproduction apparatus utilizes time division writing and reading to implement simultaneous recording and reproduction of different video signals to and from a common recording medium. In one operating mode, a first video signal being recorded and a second video signal being reproduced are simultaneously displayed in separate windows on a display. In other operating modes, two or more video signals are simultaneously recorded or reproduced to/from a common recording medium, and simultaneously displayed in separate windows.

摘要： An information processing apparatus capable of accurately detecting commercials included in a television broadcast. A commercial candidate section detector detects a commercial candidate section based on the characteristics of transitions between a program and a commercial and based on the characteristics of commercials. Transitional criteria include quiet sections, scene change points and changes in the audio multiplex mode. A commercial block detector detects a commercial block, which is composed of a plurality of commercial sections and is interposed between program portions, in conformity with the number of frames of the individual commercial candidate sections detected by the commercial candidate section detector, and then outputs to a switch a control signal based on the result of such commercial block detection.

摘要： The invention provides a broadcast signal recording and playback apparatus and method which can detect a CM included in a television broadcast signal with certainty without an error. A CM candidate period detection section detects a CM using an audio mode signal outputted from a tuner, a sound absence discrimination output from a sound absence detection section and a scene change detection output from a scene change detection section as basic materials. A detection operation discrimination section limits operation of the CM candidate period detection section when it is known that the broadcast signal includes no CM or when the electric field is weak.
