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: To improve transmission of digital broadcast information, there is proposed a method of transmitting digital broadcast information from a main transmitter (12) to at least one repeater (14). There is generated a composite digital broadcast signal carrying first digital broadcast information according to a first digital broadcast specification (DVB-T) and second digital broadcast information according to a second digital broadcast specification (DVB-H). The composite digital broadcast is then broadcasted such that the second digital broadcast information (DVB-H) is sent in a transmission mode used for transmission of the first digital broadcast information (DVB-T).

Abstract: The media session management of the invention encompasses a media server having access to multiple unicast-based media channels and a user terminal. The user terminal generates and transmits a generic, channel-transparent session request to the server. This request initiates a generic, channel-transparent media session setup procedure between the terminal and the server. The setup procedure involves exchange of requests and responses but no media channel is yet selected or notified at the server. Once the channel-transparent setup has been completed, the user terminal transmits a channel-specific rendering request for a desired media channel to the server. In a subsequent channel switch, the terminal simply transmits a new channel-specific request for a new channel to the server during the ongoing session and reusing the negotiated transport parameters of the channel-transparent setup procedure.

Abstract: The invention is embodied in 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 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 may further randomly select a delay time within a 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: 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: A technique for controlling a point-to-multipoint (PTM) transmission of data over a PTM-enabled network (150) to a user group is proposed. In a first PTM transmission, a location information query message is distributed into a group service area (154). Upon receiving the query message, items of user equipment respond with location information response messages comprising location information indicative of a location of the respective user equipment. On the basis of the received location information response messages, a content transmission area (156, 157, 158) is determined. A second PTM transmission is then initiated into the content transmission area for content distribution. Furthermore, the content may be distributed via unicast retrieval.

Abstract: A method of managing a unicast-based media session is disclosed. A user terminal having access to channel identifiers of media channels available at a media server compiles a SIP-based channel request comprising a channel identifier of one of the available media channels and a port identifier of at least one media input port of the terminal. This message is sent to a network node for initiating delivery of media data of selected media channel to the announced media input port. The SIP-based data signaling also allows switching between unicast-based media channels and switching between unicast-bast and multicast/broadcast-based media channels during the ongoing media session.

In this respect, the invention offers a technology to improve the yield of functionally expressed recombinant proteins.

Abstract: A method for scheduling the delivery of a plurality of data portions to respective recipients in a data distribution network, wherein the recipients are commonly utilizing a bottleneck element limiting the performance of the data distribution network. A proportion of recipients automatically requesting a respective data portion is determined upon receiving a respective notification message. A preferred time span for delivering the data portions is determined according to a capacity of the bottleneck element, the amount of data that is to be delivered and the proportion of recipients automatically requesting the respective data portion. The delivery of a data portion is delayed according to the preferred time span for delivering.

Abstract: A compressor (25) serves to compress headers of media packets and sends context information to a decompressor (60) for use by the decompressor in decompressing compressed headers (26) of the media packets. With regard to a flow (56) of the media packets from the compressor (25) to the decompressor (60), the compressor (60) controls inclusion of the context information in the flow in accordance with a media characteristic of the media packets. For example, in an illustrative, non-limiting illustration, a context transmission controller (46) of the compressor controls timing of generation of packets which include the context information in accordance with the media characteristic of the media packets. In one mode of operation, the predetermined characteristic which causes inclusion of the context information is media codec access information included in a payload of a packet.

Abstract: The application describes a method and system for controlling a processing of video data such that the video data may be transmitted over a connection in a communication network, where the 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 the first layer. Then one or more values of one or more video control parameters usable at the first layer are derived from the value of the least one transmission condition parameter and the processing of video data is performed in accordance with the derived one or more values.

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).

Abstract: A technique for controlling a download of an electronic service guide (ESG) for media content distribution services to a user device is proposed. First, a user behaviour related to the user device is monitored. Second, a ranking of fragments of the electronic service guide to be downloaded interactively onto the user device is determined, based on the monitoring. The download of one or more of the fragments to the user device is then initiated based on the ranking. This technique is particularly useful when a transmission capacity available for downloading fragments of the ESG is limited.
