  • Patent number: 10095575
    Abstract: A user equipment node, upon determining that the data loss in a requested file is above, or likely to be above a threshold value, transmits a delivery missing report to a server node indicating that the data loss in the requested file is above the threshold value. The delivery missing report is used by the server node for determining whether or not a multicast file repair procedure should be enabled, based on the number of delivery missing reports it has received from other user equipment nodes. This enables a point-to-multipoint file repair procedure to be enabled sooner, and prevent a flood of point-to-point file repairs.
    Type: Grant

  • Patent number: 8542622
    Abstract: A method and apparatus are provided for delivering multicast media in a network in which at least some nodes do not support delivery of multicast packets. A RTSP SETUP request is sent to a streaming server to send multicast packets, encapsulated within unicast wrappers, to a gateway node in the network. The RTSP SETUP request includes details both of the multicast destination address, and of the unicast destination address of the gateway node, requiring an extension to the RTSP protocol as currently defined and enabling the media server to send multicast packets in a unicast tunnel dynamically.

  • Publication number: 20110035768
    Abstract: The present invention relates to a server and a client for providing parental control of media content and methods thereof. In order to achieve a more flexible service deployment of the parental control, the parental control is implemented in the service consumption period according to the present invention. The operator can then offer content services which do not require a specific service order. The server sends a message to the client indicating that a parental control verification code is required in response to a request of a content during the consumption phase. A parental control verification code such as a PIN code is then inserted in a field in an authentication field originally intended for a password for authenticating the user. Thereby, parental control can be achieved even if a specific service order is not performed.
