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.

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.

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).

A scanning display apparatus (10) is described. The apparatus (10) includes a display (70) operable: (I) to receive driver signals and generate corresponding visual information for presentation on the display (70); and (ii) to sense radiation received at the display (70) and generating corresponding sensing signals corresponding to a region proximate to the display. The apparatus (10) also includes computer hardware (80) coupled to the display (70) for generating the one or more driver signals for the display (70) and for receiving the one or more sensing signals from the display (70), the computer hardware (80) being operable to provide an interactive user interface (ULI) at the display (70). The display (70) comprises an array of pixel devices (150), each such device (150) integrally being operable to emit radiation therefrom or transmit radiation therethrough, and also to sense radiation incident thereupon. Preferably, the pixel devices (150) are implemented in polyLEDs and/or LCD/TFT technologies.

A pointing device (10, 50, 70, 90) is provided for use on an interactive surface (21). The pointing device (10, 50, 70, 90) comprises a grip portion (11, 51, 71, 91) and a shapeable part (12, 52, 72, 92). The grip portion can be manipulated into different positions by a user. The shapeable part (12, 52, 72, 92) has a contact surface for making contact with the interactive surface (21). The grip portion (11, 51, 71, 91) is coupled to the shapeable part (12, 52, 72, 92) in such a way that the manipulation of the grip portion (11, 51, 71, 91) causes a footprint (30, 60, 80, 100) of the contact surface on the interactive surface (21) to take a shape corresponding to the respective different positions of the grip portion (11, 51, 71, 91).
摘要:
A method and apparatus (100) for replacing an advertisement is described. A negative input regarding a current advertisement is received (step 200). At least one feature of the current advertisement is identified which is hypothezied to have caused the received negative input (step 204). A new advertisement that differs to the current advertisement in respect of the identified at last one feature is selected )step 210). The current advertisement is replaced with the selected new advertisement (step 212).
摘要:
First and second media items are synchronized (step 210) on the basis of an extracted data item(s). A plurality of second media items are retrieved (step 206), returned, and selected (step 208) to be reproduced at the same time as occurrence of the extracted data item(s) during reproduction of the first media item.
摘要:
A system (100) has a collection of programs on a central storage device (112). The system (100) supplies a particular program to a plurality of client terminals (104, 106) in a near-video-on-demand fashion using a redundant broadcast schedule. The users of the client terminals have a maximum waiting time until the client terminal can present the start of the program. An individual client terminal (104) may offer a shorter maximum waiting time to its user by prerecording a fraction of the program that is broadcast as part of the broadcast schedule.
摘要:
A system (600), apparatus (500), and method are provided to select a best set of TV programs for reception and recording by at least one tuner said TV programs being broadcast during a given time period [b, e] having a beginning time b and an ending time e. Partial and entire TV programs are considered and for each partial or entire TV program a user preference value is provided for its reception and recording. A minimum-cost network algorithm is used that solves the selection and viewing problem to optimality (guaranteed).
