Method and apparatus for retransmission decision making

A method and apparatus are described including receiving, by a transmitter, a report from an associated client, setting and using a downlink transmit power level responsive to the report for data transmissions to the associated client, determining a downlink data loss rate and adjusting the downlink transmit power level responsive to the downlink data loss rate, wherein said report includes received signal strength, client transmit power level and one of link margin and receiver sensitivity. Also described are a method and apparatus including receiving, by a receiver, a request for a report, transmitting the requested report, receiving an instruction to use an uplink transmit power level, setting and using the uplink transmit power level, determining an uplink data loss rate and adjusting the uplink transmit power level responsive to the uplink data loss rate, wherein said report includes said received signal strength, client transmit power level and one of said link margin and said receiver sensitivity.

Method and apparatus for transmit power control in wireless networks

A method and apparatus are described including categorizing each channel into one of four categories, selecting a channel from a first category of channels, if there are any channels in the first category of channels, selecting a channel from a second category of channels, if there are any channels in the second category of channels and selecting a channel from a third category of channels, if there are any channels in the third category of channels.

Channel selection method for wireless networks

A method and system of providing a content guide that identifies a spatial relationship between the elements in the content guide is described. A controller receives electronic program guide data. The received electronic program guide data is parsed to identify a plurality of programs listed in the electronic program guide and data corresponding to at least one program description attribute for the identified programs. A relationship is determined between each identified program based on the at least one program description attribute. At least one cluster is generated and includes at least one of the plurality of identified programs based on the determined relationship. A user interface display processor generates a user interface display image representing a clustered content guide and including the at least one generated cluster enabling the user to view the relationship of the plurality of programs.

Media content spatial navigation

A method and apparatus are described including a data packet having a data packet header, storing the received data packet as shared payload, determining if the received data packet is a first data packet, initializing a sequence starting number responsive to the determination, generating a new data packet header, calculating a sequence number for the received data packet using the sequence starting number, inserting the new sequence number into the new data packet header, unicasting the new data packet header and the shared payload to a plurality of client devices.

Method and apparatus for converting a multicast session to a unicast session

A method and system of providing access to related content includes a primary display that is tuned to a desired program. Information that identifies the desired program is retrieved from an electronic program guide using a content processor. A plurality of locations on a communication network are automatically searched for additional episodes of the desired program using the retrieved information via an interne interface. Links for accessing the additional episodes of the tune program are provided via a user interface display processor on a secondary display.

Smart catch-up for media content viewing

A method and system including a controller with an internet interface of providing enhanced content is provided. The controller receives an electronic program guide data and retrieves at least one characteristic identifying a program currently being displayed on a primary display device within the electronic program guide. At least one external content source is searched using the internet interface for information related to the program based on the at least one characteristic and the information related to the program obtained during the search is stored into a memory. The information stored in the memory and related to the first program is displayed by a user interface display processor on a second display.
