摘要:
An information recording medium wherein a stream which is recorded in a constrained format allowing format conversion from a first format (MPEG-TS) to a second format (MPEG-PS) and is seamlessly connected, can be converted into a second stream, and an apparatus and method for recording information in the information recording medium. The constrained format is provided for enabling conversion from a first format (for example, MPEG transport stream) to a second format (for example, MPEG program stream). Seamless playback is performed by using a third system stream (Bridge-VOB), which is composed of each of the parts the two seamlessly connected system streams. A video information presentation time by data management unit (Capsule) at the beginning of the third system stream is greater than or equal to 0.4 and less than or equal to 1 second, according to the constrained format.

摘要:
Data for storage by holographic data storage is arranged in an intermediate data storage as data segments which are replicas of holographic storage segments. Files of data are aggregated into the data segments, and a destaging control determines the destaging of the data segments to the holographic data storage in accordance with a plurality of policies, such as whether a segment is full, a time threshold has been reached, or whether a threshold number of segments are 'open'. The intermediate data storage may be arranged into a number of partitions at least equal to the number of sources having input to the data destaging system, the partitions comprising integral multiples of the data segments.

摘要:
The present invention relates to reduction of power consumption of electronic mass storage devices, and more particularly to such a reduction of power consumption in mobile infotainment products. These devices are equipped with a subsystem comprising a mass storage device (48) and a buffer memory (43, 44). The size of the buffer memory (43, 44) is adapted in such a way that optimally low power consumption is achieved. This accomplishment by activating or deactivating memory banks (45) comprised in the buffer memory chips. The amount of memory banks (45) activated is determined by operating characteristics of the subsystem, e.g. a desired bit-rate to be achieved for transmissions to/from the mass storage device (48).
