摘要： A system for distributing digital content includes two or more digital content sources. Each source has a separate session manager that is distinct from other session managers associated with other digital content sources. The system further includes at least one set of network resources that receive digital content from the two or more digital content sources, modulate the digital content onto a carrier signal suitable for transmission over an access network, and transmit the carrier signal over the access network. The system also includes a receiving device for terminating the carrier signal. The receiving device generates a digital content stream corresponding to the digital content from the two or more digital content sources. The system further includes a policy server for allocating bandwidth of the network resources to the digital content sources, and for monitoring a utilization state of the network resources.

摘要： A transmitting method includes: inputting, per unit time, a plurality of transfer packets less than or equal to a predetermined number; and transmitting, per the unit time, the plurality of transfer packets that have been input, in a state where definitions compliant with a receiving buffer model are satisfied (S2301). Each of the plurality of transfer packets includes a variable-length packet header and a variable-length payload. The definitions compliant with the receiving buffer model are predetermined for guaranteeing a buffering operation of a receiving device, and specify converting a first packet into a second packet and outputting the second packet from a buffer of the receiving device at a predetermined extraction rate. The first packet is included in the transfer packets received and includes a variable-length packet header and a variable-length payload. The second packet has a fixed-length packet header that is extended.

摘要： Media comprising media segments (1) is played in a browser application. The segments comprise video (4) and/or audio (5) payload data encoded by a codec supported by this browser application. To play the media, several steps are performed by the browser application. First a first subset (2) of media segments of the media are obtained from a server. Then, a first media file is constructed comprising the video and/or audio payload data of the first subset of media segments. In a third step, a second subset (3) of media segments of the media are obtained from the content distribution network whereas the second subset is consequent in time to the first subset. Then, the second media file is constructed comprising the video and/or audio payload data of the second subset of media segments. Finally the first and second media file are played in the browser according to the codec.

摘要： A method is provided of providing a content-on-demand service to a user terminal in a system comprising a plurality of content-on-demand servers and a packet-switched network. The method comprises the steps of: a first of the content-on-demand servers seeking to reserve packet-switched network resources to enable service delivery to the user terminal, said first server sending a message that resource reservation was insufficient, a further of the content-on-demand servers seeking to reserve packet-switched network resources to enable service provision to the user terminal, said further server sending a message that resource reservation is sufficient, and said further server providing the content to the user terminal via the packet-switched network.
