    Abstract: A technique for registering a device (10) with a rights issuer system (12) in a digital rights management (DRM) context is described. The device (10) is provided with DRM registration information that is required to use protected content. The DRM registration information is generated from rights issuer information on the one hand and device information on the other hand. The DRM registration technique described herein does not require an interactive registration protocol between a rights issuer server (12) and the device (10). Rather, the DRM registration information may be generated and transferred to the device (10) even if the device (10) is offline, inactive or switched-off.

    Abstract: Presented is a technique for broadcasting content data from a broadcaster (including a multicaster) to a plurality of clients. After a client receives content data from the broadcaster, a plurality of available proxy servers may be contacted, within a specified time interval, for post-processing after the content data broadcast is determined. The client subsequently randomly selects one of the available proxy servers to contact for post-processing after the content data broadcast. The client then randomly selects a delay time within the contact interval for the selected proxy server, at which time the client contacts the selected proxy server at the delay time to initiate post-processing.

    Abstract: In a method for the transmission of a plurality of data packets from a sender (1) to a receiver (2), the data transmission is performed over a link (5) with a transmission capacity having a limit. A presentation time is defined for a first data packet of said plurality, and the receiver (2) performs a first check whether data packets are correctly received. At least one data packet is selected for retransmission according to the result of the first check. In the method, a delay budget (DB) is determined from the presentation time of the first data packet. Furthermore, a delay requirement is determined for the retransmission of the selected data packet from the limit of the transmission capacity and from the transmission capacity required for the selected data packet. A comparison (30) of the delay requirement and the delay budget (DB) is performed, and the retransmission is executed for the selected data packet according to the result of the comparison (30). Devices and software programs for executing the method are also described.

    Abstract: Un método para controlar un receptor (30) que está dispuesto para funcionar en un modo (2,4) operativo de recepción para recibir una cantidad de datos en una transmisión desde un emisor y uno o más modos (1-7) operativos adicionales, dicho método que se lleva a cabo en dicho receptor y, caracterizado porque comprende: establecer (S1) un indicador interno de terminación de la transmisión en un valor inicial, al inicio de dicha transmisión y subsecuentemente adaptar (S2) dicho indicador interno de terminación de la transmisión en el curso de dicha transmisión, monitorizar (S3) dicho indicador interno de terminación de la transmisión en el curso de dicha transmisión con el fin de determinar si se cumple una condición de terminación de la transmisión, y en respuesta a la determinación de que se cumpla dicha condición de terminación de la transmisión, abandonar (s4) dicho modo operativo de recepción para entrar en uno de dichos modos operativos adicionales.

    Abstract: A method for obtaining information about a transmission capability of a transmission link (TL) is disclosed. A sending entity (SE) sends data packets at a sending rate to the transmission link (TL), which transmits the data packets according to its transmission capability to a receiving entity (RE) receiving the data packets at a receiving rate. The sending rate is modulated with a rate modulation and the following steps are executed by an analysis entity (AE): obtaining the sending rate, obtaining the receiving rate, comparing the obtained sending rate and the obtained receiving rate to determine a relation of the obtained sending rate and the obtained receiving rate and to determine an appearance of the rate modulation of the sending rate in the obtained receiving rate, and obtaining the information about the transmission capability based on the determined relation and the determined appearance of the rate modulation.

    Abstract: A method of controlling a receiver that is arranged to operate in a reception operating mode for receiving an amount of data in a transmission from a sender and in one or more further operating modes, the method comprising: setting an internal transmission-over indicator to an initial value at the beginning of the transmission and subsequently adapting the internal transmission-over indicator in the course of the transmission, monitoring the internal transmission-over indicator in the course of the transmission in order to determine whether a transmission-over condition is fulfilled, and, in response to determining that the transmission-over condition is fulfilled, leaving the reception operating mode for entering one of the one or more further operating modes.
