Abstract:
A reversible fan tray device is provided for a power supply unit. The fan tray device includes a mounting panel to be removably mounted to the power supply, a fan unit secured to the mounting panel to provide airflow through the electronic device, and an interconnection board secured to the mounting panel to provide an electrical connection between the fan unit and the power supply unit. The mounting panel can be positioned in either of two orientations, the first orientation to draw external air into the power supply unit and the second orientation to force internal air out of the power supply unit. The interconnection board mates with a connector on the power supply unit when the fan tray cassette is in either of the two orientations. The interconnection board provides an airflow direction indication to the power supply unit for an existing orientation of the two orientations.
Abstract:
Multi-chassis systems determine their topology and self-organize through a discovery process. The systems include one or more chassis, each with individual blades and ports, which are serially chained together. When the discovery process is initiated, chassis identification data in buffers in each chassis is propagated to adjacent chassis and is then used to initiate communication via a network connection. Once the chassis are able to communicate via the network connection, at least one chassis in the system receives the chassis identification data of each chassis and can thereby identify each chassis. The chain is then divided into one or more sync-groups and master and slave chassis are designated. Each sync-group is configured to ignore data from other sync-groups. Domains are also configured from sets of ports within each sync-group. Events that may trigger the discovery process include power-up, the connection of a cable, the removal of a cable, or instructions to transition from normal mode to discovery mode.

Abstract:
Described herein are techniques for transmitting alert information in association with television programming in a transport stream. The alert information may be transmitted to a plurality of television receivers for which the message may be applicable to at least a portion of the television receivers. Each television receiver receives the alert information and determines whether to output the alert information for presentation to a user.
Abstract:
Disclosed is a system and method for receiving satellite television signals. A centralized system component may be provided in association with the satellite antenna. The centralized system component includes at least one or more tuners and one or more demodulators. The centralized component may provide output through a network adaptor that provides output through a single output, which is a coaxial cable in one embodiment. The centralized component may send output in the form of packetized data directed to one or more set-top boxes by way of a network transaction. The set-top box or boxes may be operable to receive the network transaction and to process the data, as appropriate, for display on a TV/monitor.
Abstract:
Systems and methods of providing different commercial viewing options for a media content event are disclosed. An example media device receives a user selection identifying one of a plurality of commercial viewing options associated with a media content event; determines if commercials are to be presented within at least one commercial break of the media content event based on the received user selection; selects commercials for presentation based on the received user selected commercial viewing option if commercials are determined to be presented during the at least one commercial break; presents the media content event; and presents selected commercials during designated commercial breaks during presentation of the media content event if commercials are determined to be presented during the at least one commercial break.
Abstract:
Protocol analyzers systems and methods coordinate the capture of network data of interest across multiple chassis. Each chassis has individual blades with accompanying ports and is serially connected to other chassis in the system. Selected ports from each chassis are configured in domains that can be spread across the serially connected chassis and used in coordination to capture network data of interest. A serial protocol containing control signals is used to transmit run, stop, and trigger data between the serially connected chassis and thereby coordinate the activity of ports within each domain. Through the use of the serial protocol the number of wires connecting adjacent chassis is minimized and each of the blades in the multi-chassis systems can be synchronously started, stopped, and triggered at the same time to synchronously capture the network data of interest.
Abstract:
Systems and methods enable three dimensional (3-D) program content viewing in a media environment with different media presentation devices. An exemplary embodiment detects a first synchronization signal transmitted from a first synchronization signal source, wherein the first synchronization signal is associated with first 3-D program content and includes a first signal identifier; detects a second synchronization signal transmitted from a second synchronization signal source, wherein the second synchronization signal is associated with second 3-D program content and includes a second signal identifier; receives a selection of one of the first synchronization signal and the second synchronization signal; discriminates between the first synchronization signal and the second synchronization signal based upon the first signal identifier and the second signal identifier; and controls a left lens and a right lens of 3-D shutter glasses in accordance with the selected one of the first synchronization signal and the second synchronization signal.

An active response network tap for use in monitoring a network comprises a first device interface terminal, a second device interface terminal, a first monitor interface terminal, and a second monitor interface terminal. A tap structure is coupled to the first device interface terminal, second device interface terminal, first monitor interface terminal and second monitor interface terminal. A memory is coupled to the tap structure and configured to store data. In one aspect, the tap structure is configured to communicate full-duplex traffic between the tap structure and a monitor device coupled to a monitor interface terminal. In another aspect, the tap structure is configured to insert data from a monitor coupled to the first monitor interface into the traffic between the first device and the second device. Advantages of the invention include the ability to provide monitor access to a network while also supporting communication with other network devices.
