摘要： In a multimedia streaming network where a client has a receiver buffer to store a plurality of packets received from a server so as to compensate for the difference between data transmission amount by the server and data usage amount by the client, the server should be able to adapt the data transmission rate based on the status of the receiver buffer. For rate adaptation purposes, server reconstructs a list of packets in the receiver buffer based on information provided by the client. The information signaled to the server is indicative of the next unit to be decoded and the sequence number of the packet to which the next unit to be decoded belongs.

摘要： A method, system, device and software code product are disclosed which provide efficient multicast/broadcast distribution of formatted data. Formatted data can comprise metadata and content (media data) and several embodiment of the inventions disclose retransmitting the metadata in order to increase the reliability of the file distribution by increasing the chances that the metadata is received without error. In addition, embodiments of the invention disclose scheduling transmission of data packets of formatted data so that the metadata packets are transmitted at an earlier time location than they occur in the original formatted data file to decrease latency in file playback.

摘要： A method for improving a cooperation between a packetized data bit-rate adaptation and a data packet re-transmission transmits data packets from a server to a client with a first bit-rate; stores transmitted data packets in a server buffer; stores transmitted data packets in a client buffer; signals impairment information related to an impairment of transmitted data packets during transmitting to the server, wherein the signaled impairment information is analyzed by the server to decide if a re-transmission of data packets stored in the server buffer is required; and signals client buffer information related to a state of the client buffer to the server, wherein the client buffer information is analyzed by the server to decide if a re-transmission of data packets is required.

摘要： A method used for communicating packets or other information units from a server (11) to a client (15) over a communication path including a packet scheduler (14-1) followed by a bottleneck path (14-2), with the packet scheduler (14-1) having a buffer for holding packets so as not to transmit over the bottleneck path (14-2) at a rate either too high or too low, the method providing that the server (11) communicate to the client (15) sender information indicating the last packet sent to the client (11) by the server (11) and do so via a mechanism by which the sender information is communicated over the bottleneck path (14-2) ahead of substantially all packets already in the buffer. The client (11) then uses the sender information to provide, as needed, information useful in adapting the rate at which the packets arrive at the packet scheduler (14-1)

摘要： Methods, systems, transmitters, receivers, network elements and software applications in a system for acknowledging the reception of sets of data objects, wherein one or more transmitters transmit one or more sets of data objects within respective point-to-multipoint transmission sessions to a plurality of receivers, and wherein repair requests and/or delivery verification reports are transmitted by at least one of said receivers to network elements within point-to-point transmission sessions. Different back-off times are assigned for delivery verification reports and repair requests, at least two delivery verification reports of one receiver are jointly transmitted within one point-to-point transmission session, and a delivery verification report is transmitted after a completed repair session within the same point-to-point transmission session used by the repair session. Furthermore, a minimum set of parameters to be sent in delivery verification reports is shown.
