Abstract: A multimedia processing device implements a script having a data structure that is formed of a drawing information describing portion where media data is chronologically described, and a user navigation information describing portion where correspondence between events and actions and implementation conditions are chronologically described. The multimedia processing device implements this script, and thereby, media data is chronologically reproduced, and at the same time, a user interface showing operations that can be chronologically carried out is outputted. Then, a predetermined process, such as an insertion of media data, can be implemented by carrying out the operations following the user interface according to predetermined timing.

Abstract: A system and method manages Quality-of-Service (QoS) in a network by allocating resources, such as available network bandwidth. The network devices transmit and receive data traffic streams, each of which includes QoS parameters, including a priority level and bandwidth allocation. The method includes choosing which existing QoS allocations are pre-empted, notifying original requesters of pre-empted allocations, and re-establishing pre-empted allocations with appropriate modifications. If a new QoS request cannot be accommodated due to the previous allocations to lower-priority requesters, the existing lower-priority allocations are released until enough allocations are released to accommodate the new request. Once the new request is allocated, the pre-empted configurations may be reallocated.

Abstract: A system and method in a local area network based on the Universal-Plug-and-Play (UPnP™) technology represents an infrared (IR) remote control (RC) pass-through protocol in the Content Directory Service (CDS) of a media server that transmits an audio-video (AV) media stream over the network to a media renderer. The CDS includes a listing of media content items that represent media source devices that provide media content to the media server, and a listing of associated IR pass-through protocol identifiers (IRPT-IDs) for each media content item. Each IRPT-ID identifies an IR pass-through encoding/decoding protocol usable by the IR decoder in the media server and each IRPT-ID has an associated internet protocol (IP) connection point (IRPT-CP). The media renderer browses the CDS to identify the media content item and its associated IRPT-ID/IRPT-CP pair. The IR RC at the media renderer sends RC commands to the media renderer that are encoded using the IR pass-through protocol represented by the IRPT-ID.
