摘要:
The apparatus is suitable for managing a data carrier (1) obtaining a fast data transfer from it to the apparatus when the carrier is driven with a constant angular velocity (CAV). It comprises a motor (3) for driving the carrier, an optical head having light source (16) for reading and/or writing data stored form and in it. Furthermore, it comprises means, involving a processor set (50) for determining the frequency of the use of files contained in the data carrier, such that the more frequently used ones are put in a location for a faster transfer. While the transfer is being performed, the motor and the light source arc stopped so that supply energy is economized, which is interesting for a battery-operated apparatus. Application: The invention is well suited for small size R/W optical discs (SFFO).

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.

A service that provides playback of media content, that may include advertising content, to a user. The system comprises device, that may be a portable wireless device, where the wireless device has a media drive and an application that reads content from a medium inserted in the media drive. The system further comprises a service that communicates with the wireless device via a wireless network. The service provides control commands to the application program for controlling playback of content from the medium when inserted in the media drive. The service may also provide advertising content to the user based on a user profile. A fee may be paid for the delivery of the content and/or the advertising to the user.

A method and a system for mobile ad-hoc Internet sharing. The system comprises a first portable device (10) that is provided with wireless communication capability (11) and that is enabled to identify a user A of the device (10), a second device (20I;20II) that is provided with wireless communication capability (21I;21II) and with capability (22I;22II) to connect to the Internet via an ISP, and that is enabled to identify a user B responsible for the connection, and an ISP (30). The method comprises wirelessly sending information from the first device (10) to the second device (20I;20II), for initiating a connection between the first device (10) and the ISP (30), forwarding the information from the second device (20I;20II) to the ISP (30), identifying, at the ISP (30), that the information is sent from user B and originates from user A, and initiating, at the ISP (30), registration for charging of an account (36) of user A for said connection.
摘要:
A data processing apparatus (800) has an input (810) for receiving a first and second sequence of frame-based A/V data. A processor (830) edits the two sequences forming a third combined sequence. So-called “I-frames” are intra-coded, without reference to any other frame of the sequence. “P-frames” are coded with reference to one prior reference frame, and “B-frames” are coded with reference to one prior and one subsequent reference frame. The referential coding of a frame is based on motion vectors in the frame indicating similar macro blocks in the frame referred to. The processor identifies frames in the first sequence up to and including a first edit point and frames in the second sequence starting at a second edit point that have lost a reference frame. The processor (830) re-encodes each identified B-frames into a corresponding re-encoded frame by deriving motion vectors of the re-encoded frame solely from motion vectors of the original B-frame.

Portable devices for rendering multimedia data objects are widely known; mainly for reproducing audio, but also for reproducing video. These devices are powered by battery, which is known to have a limited amount of energy available. This carries the risk that no energy is available any more, while a multimedia data object that is rendered, is not rendered in full this leaves a user unsatisfied. Therefore, the amount of energy of the battery is checked and when a multimedia data object selected to be rendered can be rendered in full, it is rendered. When it cannot be rendered in full, it is not rendered. In an embodiment according to the invention, this check is made for a group of selected multimedia data objects.

A method and apparatus for recording a data stream on a storage medium for improving non-linear playback performance of the recorded data is disclosed. First, the data stream is received. The I-pictures from the data stream are stored in a first buffer and the remaining data from the data stream is stored in a second buffer. Each time the first buffer becomes full, the I-pictures stored in the first buffer are written onto an intra-coded allocation unit on the storage medium. Then, the contents of the second buffer are written onto preferably a subsequent inter-coded allocation unit.

The invention provides a method and system for obtaining updated information using a portable disk-based information device. The disk-based information device may be included within or attached to a portable networking device such as a personal data assistant (PDA) or a cellular telephone. Update information may be received from a data provider through, for example, a mobile telephone network. The update information may be compared with information provided on the disk. Updated information may then be delivered to a user in response to a user request, reporting new information and replacing outdated information provided on the disk with information received from the data provider.
