    摘要： In some cases, an IPTV client may send multiple IGMP Report/Join requests to an IPTV gateway, primarily due to a system or software failure. This may flood the IPTV client device with unwanted streaming data. A method and an apparatus for managing Internet Group Management Protocol (IGMP) multicast groups of IPTV service are suggested. The method comprises receiving a request from an IPTV client device for joining a new IGMP multicast group of IPTV service; and adjusting IGMP multicast groups of the IPTV client device according to a preset rule as a function of the number of the IGMP multicast groups which are joined by the IPTV client device over a preset value. According to the disclosure, only a preset number of IGMP groups are allowed for an IPTV client device, which can reduce the risk of streaming data flooding the system.

    摘要： A communications module, a gateway device incorporating the communications module, or a local network system incorporating the gateway device, incorporating a readily installable and removable module which contains internal computer instructions to operate a digital video recorder which may be controllable using the local network system. The module may control at least one of the functions including dynamic video up-conversion, pausing, and recording. The module may obtain timing data from the network with which it is associated.

    摘要： An apparatus and a system are provided to proxy one or more media signals between at least one local client device and at least one remote client device. For instance, the apparatus can include a first network interface, a rate controller and media transcoder, and a second network interface. The first network interface receives a plurality of media signals over a first communication network, where the plurality of media signals is encoded into at least one codec format. The rate controller and media transcoder transcodes one or more of the plurality of media signals into a different codec format based on channel and processing capabilities associated with one or more local client devices and one or more control messages. The second network interface transmits the one or more of the transcoded plurality of media signals to a respective plurality of remote client devices over a second communication network.
