Methods, systems, apparatus, including computer programs encoded on computer storage media, for generating and routing modified multimedia data frames. In one aspect, the method includes maintaining, by a first network node, channel membership data that includes data indicating, for each channel of a plurality of channels, leaf node membership for a plurality of channels, and for each channel of the plurality of channels: determining, based on the channel membership data, the leaf nodes that are subscribed to access the channel, generating, based on the leaf nodes that are subscribed to access the channel, a modified multimedia data frame for the channel that includes (i) a hub node identifier, (ii) data that describes a destination address of each leaf node that is subscribed to access the channel and (iii) a payload, and transmitting, by the first network node, the generated modified multimedia data frame to a second network node.

An example method is described in which a controller initiates, with a control point, control point discovery for an endpoint managed by the control point. The controller, receives, from the control point, a message in response to the initiation of control point discovery. The message is an Internet Protocol Detail Record (IPDR) message or Simple Network Management Protocol (SNMP) message that includes registration information of the endpoint. Based on the registration information of the endpoint, the controller determines an association between the control point and the endpoint. This allows the controller to apply a controlling function on the control point when the endpoint accesses a service via the control point.

A method (300) for extending television content by a system comprising the steps of establishing (302) an IP address for the system through DHCP server, with or without local domain name, establishing (304) a wireless intranet network for a plurality of portable user devices to get connected, receiving (306) a plurality of input signals that contains a plurality of television content, processing (308) the received plurality of input signals in real-time, connecting (310) the plurality of portable user devices with the established wireless intranet network and assigning unique IP for each device through DHCP server, and broadcasting (312) the processed plurality of input signals as plurality of live media streams along with channel change options to the connected plurality of portable user devices for accessing and rendering the plurality of live media streams via the connected wireless intranet network.

Disclosed are methods, apparatus, systems, and computer-readable storage media for representing a portion of a user interface of a web browser as a web address. In some implementations, a computing device receives a request to encode as a web address a portion of a user interface provided in a web browser at the computing device. The computing device then generates a web address to identify content of the portion of the user interface. The portion of the user interface represented by the web address includes a primary user interface component and one or more secondary user interface components associated with the primary user interface component.
