A method of relaying data between mobile stations in a cellular communications system is provided. The system comprises a number of mobile stations and base stations. Each base station makes synchronization transmissions within its area of covers, which define a broadcast control channel for the transmission of broadcast data from the base station to mobile stations within the area of coverage. The synchronization transmissions are received at mobile stations within the area of coverage, which extracts data defining the broadcast control channel, and at least one calling channel on which mobile stations can transmit probe data to one another. The probe data is used by the mobile stations to obtain connectivity information relating to the availability of other mobile stations. The synchronization transmissions also contain data which is used to define at least one traffic channel which is used by the mobile stations to relay message data between themselves. Effectively, the method of the invention provides a hybrid system which combines conventional cellular technology with opportunistic relaying technology.

A method and apparatus for supporting a priority transmission of broadcasting data in a transmitter of a digital broadcasting system.

The data of the broadcasting service is mapped to the plurality of subchannels according to the priority. Data streams mapped to the plurality of subchannels are encoded in different encoders and the encoded data streams are transmitted.

An interactive television system includes a plurality of client devices connected to a server through a network. The client devices display broadcast contents based on received broadcast data. Icon buttons are displayed superimposed on the displayed broadcast contents. Each icon button represents a different icon. When one of the displayed icon buttons is selected at one of the client devices, then the client device sends a request to the server, asking to execute, at another client device, an icon represented by the selected icon button. When the server receives the request over the network, the server sends icon identification data that corresponds to the icon over the network to the other client device. The other client device executes the icon based on the received icon identification data.

The invention is directed to techniques for maintaining a map of node relationships for a network of nodes (e.g., network of computers). In one example, the map of node relationships represents relationships overlaying and typically different from the network of physical connections among the nodes. Each child node periodically checks in with its parent nodes, and the parent nodes can thus determine when a child node has terminated a relationship with the parent or created a new relationship with a new parent. Changes in relationships propagate upward through the network of nodes so that each node maintains a map of the relationships among the descendants of that node. A root node receives the propagated change relationship information and maintains a map of the entire network and valid pathways through the network. The root node can use the map when responding to a request from a client to receive services from a node in the network and redirects the client to attach to a node in the network that has a valid path to the root node. The root node can then broadcast data (e.g. a stream of video data) throughout the network, which is received by all the clients attached to nodes in the network.

A system and method for recording and playback of game data is provided. A recording engine may be configured to record and playback game data, including broadcast data received over a network. The recording engine may be included in a game console or at other network-enabled devices, such as a desktop computer. The recording engine may be configured to record the game data in a buffer memory, an archival memory, and to assist in the display of the game (e.g., interacting with a graphics processing unit). Game data stored in the buffer memory may later be transferred to the archival memory. Playback commands may be operable when a portion of the game broadcast has been recorded. When a playback command is received, the game recording engine may access a portion of the game data from buffer or archival memory and displays a selected portion and may be subject to certain seek functions (e.g., fast forward and rewind). Spectators may be able to independently archive and playback game data using local memory.

A communication apparatus that shares precise return channel uplink timing information includes a common symbol timing reference and one or more control stations that each transmit independent asynchronous DVB data streams which evenly share the common symbol timing. The control stations each include respective delay trackers to determine broadcast transmission delays associated with the particular control station and transmission path. Each broadcast data stream includes the same non real-time frame marker and a transmission delay message particular to the respective control station. A remote receiver receives one of the broadcast streams and timestamps the non real-time frame marker with a local time of receipt. A timing recovery circuit determines an upcoming return channel frame start time by adjusting the local time of receipt by the particular broadcast transmission delay and a unique receiver offset time. A local transmitter subsequently uplinks a TDMA message in a predetermined time-slot after the return channel frame start time. The method for transmitting a frame synchronized message includes receiving a non real-time frame reference marker in a receiver, timestamping the received frame reference marker with a reception time, and subsequently receiving a control node timing differential at the receiver. The local reception time of the non real-time frame marker is corrected to determine the proper return channel frame transmit start time by applying the control node timing differential and the local offset time. Users then uplink a message during an assigned period after the return channel frame transmit start time.
