Abstract: A method and system for controlling a processing of video data such that said video data may be transmitted over a connection in a communication network, where said connection employs a plurality of protocol layers. The processing of video data for transmission is performed at a first layer. A value or values of one or more transmission condition parameters indicative of transmission conditions in the network are acquired, where these transmission condition parameters are specific for a second layer provided lower than said first layer. Then one or more values of one or more video control parameters usable at said first layer are derived from said value of said at least one transmission condition parameter and the processing of video data is performed in accordance with the derived one or more values.

Abstract: A system, method, and media edge proxy, MEP, for providing media data such as Internet Protocol Television, IPTV, or Internet radio channels to a media client. The MEP obtains the media data from a media server utilizing a temporary unicast connection and provides the media data obtained from the server to the media client for an initial time period. Upon determining that the initial time period has expired, the MEP obtains the media data via multicast from a multicast router, provides the media data obtained from the router to the media client, and releases the temporary unicast connection. The invention reduces channel switching delay and thus improves quality-of-experience for the end-user. The invention also avoids excessive IGMP JOIN/LEAVE signaling when a user switches quickly through channels.

Abstract: A technique that permits an earlier start of the decoding and play out of media frames received via a point-to-multipoint transmission is described. The media frames comprise frames of a first type that cannot be decoded without knowledge of supplemental information and frames of a second type that include the supplemental information. According to a method aspect of this technique, frames of the first type are received and immediately buffered without waiting for reception of a frame of the second type. In a next step, a request message requesting supplemental information required for a decoding of the buffered frames of the first type is sent. Upon receipt of the requested supplemental information, the buffered frames are decoded based on the received supplemental information.

Abstract: Un método para emitir datos de contenido desde una entidad emisora (110) a una pluralidad de clientes (120, 122, 124, 126, 128), el método que comprende los pasos de: - recibir, por un cliente (120, 122, 124, 126, 128), datos de contenido emitidos desde la entidad emisora (110); - determinar, por el cliente (120, 122, 124, 126, 128), una pluralidad de servidores intermediarios disponibles (130, 132, 134, 136, 138) que pueden ser contactados para post-procesado después de la difusión de los datos de contenido, en donde la pluralidad de clientes (120, 122, 124, 126, 128) es diferente de la pluralidad de servidores intermediarios (130, 132, 134, 136, 138); - seleccionar aleatoriamente, por el cliente (120, 122, 124, 126, 128), uno de los servidores intermediarios disponibles (130, 132, 134, 136, 138) a contactar para post-procesado después de la difusión de los datos de contenido; y - contactar, por el cliente (120, 122, 124, 126, 128), con el servidor intermediario seleccionado (130, 132, 134, 136, 138) para iniciar el post-procesado.

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.

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.
