摘要： A method (2) of controlling memory usage in a portable streaming device (100), a portable streaming device (100) and a computer readable medium (110). The portable streaming device (100) comprises at least one memory (102), at least one processing unit (101), and at least one storage device (103) being operatively connected with said memory (102) under control of said processing unit (101). The size of a disk scheduler buffer memory within said memory in said portable streaming device is adaptively maximised by said method (2) at all times. Free memory available within the portable streaming device is continuously allocated (50) and at least a portion of said allocated free memory is designated as disk scheduler buffer memory (60). Thus results improved solid state memory utilisation of the portable streaming device, and due to larger available disk buffer memory size, less start-stop-cycles of the storage device are initiated, which leads to a longer life-cycle of said portable streaming device.

摘要： A broadcast system 100 for broadcasting at least one title using a near-video-on-demand broadcasting protocol includes a plurality of broadcast receivers 150. A hierarchical network of data distributors starts from a central distributor 110 through at least one layer of intermediate distributors 120, 130, 140 to the broadcast receivers for broadcasting the title as a sequence of data blocks. A least one filter controller 180 receives requests from broadcast receivers for the supply of the title and controls at least one intermediate distributor to filter out data blocks of the title that have not been requested by receivers hierarchically below the intermediate distributor.

摘要： The invention relates to real-time handling of data in more in particular, estimation of time needed to retrieve frames for video rendering, taking fragmentation of frames into account. Especially for data retrieval for trick-play, this is non-trivial, as it is not known on beforehand whether the frames to be retrieved are fragmented. Retrieval of non contiguously fragmented frames takes at least twice as much time as retrieval of a non-fragmented frame. The invention provides various advantageous embodiments, taking into account that when allocation units are substantially larger than the size of frames to be retrieved. An embodiment of the invention provides a method for accurate retrieval time estimation when trick play speed, allocation unit size, frame size and logical data distance between frames to retrieve is known.

摘要： This invention relates to methods of searching for a final number of result strings (30-33) having a partial or an exact match with a query string (34) in a database (80) comprised of many long strings or a long string, said method includes the steps of partitioning the query string in a first number of input query strings (35, 36, 37); determining a second number of neighboring strings (38-41, 42-45, 44-49, respectively) for each string in said first number of input query strings, wherein each string in said second number of neighboring strings has a predetermined first number of errors; searching the database for a third number of exact matches (50-61, 70-74) for each string in said second number of neighboring strings based on a search method; concatenating said searched exact matched strings from the database into a fourth number of intermediate strings (29, 30, 32, 33, 34) wherein said searched exact matched strings (50-61, 70-74) comprised in each of said intermediate strings are in succession to one another in said database; and determining the final number of result strings (30-33) based in said fourth number of intermediate strings, wherein each string in the final number of result strings has a maximum of predetermined second number of errors compared to said query string (34). This enables for a perfect match or a partial match containing only minor errors with respect to said query string, and for a fast search in larger databases with a relative low use of processing power.

摘要： A personal recorder/playback system (10) includes a recording agent (32) configured to transparently receive multiple audio/visual streams from analog and/or digital sources. The streams are temporarily stored in queues (52,54) for subsequent analysis. The streams, after analysis, are either discarded, stored permanently in an audio/visual collection (48,50), or used to improve the quality of previously stored streams in the collection. The recording agent (32) provides features such as virtual channels (42) and a “top-ten” list (38) of most popular stored audio/visual streams.

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).

摘要： A total amount, M, of memory is allocated over streaming data buffers (86). The memory is partitioned over a set of streams (88), each stream being given a partitioned amount of buffer memory. Scheduling is repeatedly performed during each filling/emptying cycle. The scheduling includes: spinning up a storage disk (80), filling/emptying each stream buffer by reading/writing from/to the storage disk until the respective stream buffer is full/empty, determining an earliest next spinning up time, putting the storage disk in standby mode, spinning down the storage disk, re-determining, at or just prior to the earliest next spinning up time, a new earliest spinning up time based on current buffer fullness, iteratively re-determining the new earliest spinning up time until the time is within a predetermined closeness to the previous time, or within a predetermined closeness to the current time, and waiting until the next earliest spinning up time, or just prior to that time.

摘要： A device for scanning a record carrier has a head for scanning a track for reading and/or writing information. A disc scheduler controls receiving requests for accessing the record carrier, the requests including streaming requests regarding real time information and auxiliary requests (44) regarding auxiliary information. The disc scheduler reduces power consumption of the device by switching the scanning means to a stand-by mode when no requests are pending and switching the scanning means to an operational mode when a request has to be executed. The auxiliary requests are executed in a processing interval (45) in combination with a selected one of the streaming requests. Hence the number of spin-ups of the record carrier is reduced.

摘要： A broadcast system for broadcasting data streams includes a hierarchical network of data distributors starting from one central distributor (110) through at least one layer of intermediate distributors (120, 130, 140) to a plurality of broadcast receivers (150). Data streams are broadcast through downstream channels (160) of the network to the plurality of broadcast receivers. At least one distributor hierarchically below the central distributor is operative to insert broadcast data in at least one up-stream channel (170) of the network towards the central distributor. The central distributor is arranged to re-distribute broadcast data received via at least one up-stream channel through at least one downstream channel of the network.
