Abstract: In a system for viewing accumulated contents by using a cellular phone, if an error prevents the content to be viewed, a simple operation is performed to view the rest at home. In accordance with a viewing request from a cellular phone, a television receiver (100), while sequentially receiving data from D-VHS (130), converts the data into a format suitable for reception and play in a cellular phone (300) by using an encoder (122). After this format conversion, the television receiver (100) stores in a play position memory (124) a time stamp indicating a position information of a content and a sequence number used for transmission in TCP/IP. The cellular phone notifies the television receiver (100) of a decode error of a reception data. When receiving a confirmation response of a normal play from the cellular phone, the television receiver (100) clears the data of the play position memory (124), and otherwise holds the data of the play position memory (124).

Abstract: A method and system for sensing and reporting various types of user presence using 'buddy list' applications. A buddy list client senses various types of user presence of a user and sends status information corresponding to the sensed user presence to a server. The buddy list client also receives status information from the server corresponding to various types of user presence information of buddies, and displays a buddy list indicating the various types of user presence information of the buddies. This can be implemented on an IPTV client in order to sense and display presence information relating to a user watching television.

Abstract: The invention relates to media management and combats media degradations arising when transcoding the media (1OA, 30A). The invention solves this by- generating processing hints based on the media transcoding. The hints are employed for controlling a post-transcoding processing of the transcoded media content (1OB, 2OB, 30B) in connection with rendering the media. The hints and this controlled processing increases the user-perceived quality when rendering the media (1OC, 2OC, 30C) by mitigating the media degradations caused by the transcoding. The processing hints could specify how the actual transcoding was performed by including values of the employed transcoding parameters or information of the alterations to the media (1OB, 2OB, 30B) caused by transcoding. Furthermore, instructions or commands for appropriate post-transcoding processing could also be processing hints according to the invention.

Abstract: A broadcast transmitting apparatus, method of transmitting broadcast data, broadcast receiver, and method of receiving broadcast data are disclosed. If data of a contents guide is updated, updated information of the contents guide is transmitted to the broadcast receiver. The broadcast receiver receives the updated information and can determine whether the contents guide data has been updated, based on the updated information. Therefore, the updated contents guide data can be requested and received as needed, thus reducing burdens of a network and receiver. Further, the receiver can maintain the latest information about contents, so as to increase reliability of information.

Abstract: Activity-based or experienced-based operations are created and defined during an initialization or setup session for one or more system component, with minimum or no user interaction. The system components include legacy and/or non-legacy devices, which are configured and managed within a controlled environment, such as a home or business peer-to-peer or client-server network. During an initialization or setup session, relevant device information and device metadata are collected via a conventional or discovery protocol interface. For a legacy device that is not automatically discoverable, a user adds the legacy device to the controlled environment by inputting the device information. The device information can also be automatically collected from an accessible database. Once the device information has been collected, the system components are configured to support one or more activity-based or experienced-based operations.
