Abstract:
It is desired to link photo data and video data taken by a digital camcorder. Therefore, there is provided a device and method for linking multimedia data, wherein linking information is formed on the basis of first and/or second multimedia data. The linking information is stored on a recording medium together with the first multimedia data. The second multimedia data may be stored together with respective linking information to the first multimedia data on a second recording medium. Thus, a camera-man while recording is able to set up logo or index pictures for a video film.

Abstract:
An architecture for a multimedia peer-to-peer home network allows the simple definition of peer groups, or zones, where each peer is capable of automatically identifying whether other peers are members of the same group, or of another group, by using group labels. Each peer may freely cooperate with the other peers of the same group, or with peers of previously specified other groups. e.g. exchange information or share resources. The architecture aims to map an atmosphere of trust existing between users to a technical system. namely their respective home networks. Using this architecture, it is e.g. possible that users who trust each other may give each other access to their own home network, or parts of it.
Abstract:
Motion-compensated hybrid codecs are used in data compression for moving picture sequences. By virtue of the regular insertion of intraframe-coded pictures, these compression methods enable access to any desired individual pictures in the entire bit stream or the playback of the bit stream from virtually any desired location. A disadvantage is the high bit outlay necessary for intraframe-coded pictures. In a feedback loop, a codec usually contains a simulation of the receiver-end decoder, whose coding errors can thus also be taken into account by the encoder. According to the invention, an attenuation element is inserted into this feedback loop. The coding and the receiver-end decoding of intraframe-coded pictures becomes superfluous. After the receiver-end decoding of a few pictures, beginning with a grey-scale picture as starting picture, a viewer does not perceive a difference between picture sequences which are coded in a known manner, and contain I pictures at relatively short intervals, and picture sequences which are coded according to the invention.
Abstract:
The handling of large amounts of data on storing media shall be simplified. Therefore, a method for maintaining a storage media by generating, editing or reading log data related to the content and usage of a data item stored or to be stored on a storage medium is provided. Data items are deleted or recommendations for deletion are provided on the basis of the log data from the storage medium. Thus, the user is relieved from the unpleasant and time-consuming task of deleting data items from recording media.
Abstract:
An architecture for a multimedia peer-to-peer home network allows the automated definition of peer groups, or zones, by using group labels, where each peer is capable of automatically identifying whether other peers are members of the same group, or of another group, and where each peer may freely cooperate with other peers of the same group, e.g. exchange information or share resources like storage capacity. Using this architecture, it is e.g. possible that a user who is accessing a node within a peer group has also access to any other node of the peer group, without being requested for authentication. Another characteristic is that other peer groups can be defined which have access rights to network resources and services. Advantageously, the invention simplifies network creation and operation by not requiring the user to have special networking knowledge.
Abstract:
Metadata transmitted in parallel to the broadcast information shall be made accessible independent of Internet availability. Therefore, it is proposed to download and store the data located on an Internet address pointed at by metadata link information. The storage is performed in parallel to the recording and is typically done onto the same media; i.e. DVR, hard disk, etc. By playing back the recorded data it is possible to access the complete data including all Internet pages pointed at.
Abstract:
The present invention relates to a hand-held device comprising connection means for supporting an internet data transmission link between the hand-held device and the internet; browser means for fetching internet data from the internet; input means for receiving a user input; and generating means for generating a command script in response to said user input, where said command script is related to said searched internet data; where said command script, when the hand-held device is connected to a multimedia home device, can be processed to initiate a transmission of at least part of said searched internet data and/or other internet data to said multimedia home device.
Abstract:
Several data streams contain video, audio and/or other data. Some of the data streams are pre-recorded in a multiplex on a storage medium while other data streams are located out of the data stream multiplex on the storage medium. The data streams are synchronized using a navigation file (List_of_PlayItems), which comprises descriptors (PlayItems, SubPlayItems) pointing to parts of said data streams, wherein said descriptors define the arrangement in time for said data streams by means of data sub stream paths.
Abstract:
MPEG video uses motion compensated prediction for coding pictures. A GOP includes at least one intra-coded picture to start decoding with and a number of inter-coded pictures and normally also includes bi-directionally predicted pictures. However, the GOP structure is not constructed for playing GOPs in backward direction in a trickplay mode across GOP boarders. The invention facilitates, for different GOP structures, a smooth backward video mode thereby reducing the required number of frame buffers and achieving near real-time speed presentation. In some embodiments some I and/or P pictures are decoded more than once. The invention also allows backwards decoding of MPEG-4-AVC GOPs including B-stored pictures.
