The present technology relates to information processing apparatus and method, and a program that make a stress level controllable depending on circumstances. A stress level measuring unit measures a stress level of a user on the basis of a result of detection by various types of sensors included in an input unit. A stress factor specifying unit specifies a factor causing an increase or decrease in the stress level on the basis of an action of the user in a period in which the stress level is increased or decreased. The present technology is applicable to a stress control system, for example.

Information processing apparatus and method

The failure isolation method includes: a first step of performing a predetermined action for the monitoring target, collecting a failure event which is a result of the action, applying the failure event to a failure cause analysis rule, and narrowing down the root cause events together with certainty factors; a second step of determining whether the root cause event and the certainty factor narrowed down in the first step satisfy a predetermined requirement and whether the narrowing-down has been completed; and a third step of, when it is determined in the second step that the narrowing-down has not been completed, performing a predetermined additional action for the monitoring target, collecting an additional failure event which is a result of the additional action, applying the additional failure event to the failure cause analysis rule, and narrowing down the root cause events together with the certainty factors.

Failure isolation method and management server for failure isolation

[Object] To prevent image quality deterioration due to unnecessary format conversion. [Solution] An STB (set top box)receives bit stream data that is transmitted from a broadcast stationin such a manner as to be carried on a broadcast wave, and obtains stereoscopic image data, audio data, and the like. Furthermore, the STBtransmits the stereoscopic image data and the audio data to the TV (television receiver)through the digital interface of HDMI. In a case where the received stereoscopic image data can be handled by a TVand, furthermore, the TVhas requested that transmission of the stereoscopic image data be performed without performing format conversion, the STBdoes not convert the format of the received image data, and transmits the received image data to the TVin the as-is format. Furthermore, in the case of other cases, the STBconverts in advance the format of the received stereoscopic image data into, for example, a format that is set by the user, and transmits the stereoscopic image data to the TV

Image data transmission apparatus, image data transmission method, and image data receiving apparatus

An interconnection between fully synchronous networks and next-generation frame communications networks is disclosed. A means of bidirectional frame format conversion between a synchronous multiplexing system and a logical multiplexing system is provided, along with a method of transmitting data between different networks on a path as if it were being transmitted in the same network. Further, when converting network control information in an STM network into data suitable for a packet network, even across the boundary of a synchronous multiplexing system and a logical multiplexing system, a unified communication management means is provided over the whole path.

System apparatus and method for interconnecting TDM and frame/packet communication networks

To prevent, in using a multicast DA in an OAM frame, an increase in the network bandwidth usage and in the load of node processing and a degradation of the network reliability caused by a frame being transmitted to all routes in a broadcast domain. A MAC address and other basic frame information and the MEGID are associated with each other, and the MEGID information is added to the OAM frame, and these information are transmitted from an edge node serving as an end point of an ME. In a relay node of the ME, a route control table used for OAM frame control is provided, and a filter is generated by snooping of the OAM frame. Furthermore, when the relay node does not support the OAM function, the MEGID is denoted by a VLAN tag and the route control is made using the snooping function of each VLAN tag.

Network system and data transfer device

Provided is a multicast path management method for a connectionless communication. Also provided is a path protection function which is effective when a path has failed. A network is formed by a trunk and a branch path. The multicast path is managed by end-to-end and when a failure has occurred, an instruction is issued from the apex of the multicast tree to respective end-to-end paths so as to switch from the currently used channel to a backup path. Thus, upon failure, an individual path protection can be performed without affecting other parts of the tree to which the same multicast flow as the defective path is distributed or the distribution state of the multicast flow.

Multicast path management and protection

A transmission apparatus for use in fixed bandwidth communications and variable bandwidth communications. The transmission apparatus has a memory unit, which stores information contained in a frame and indicating the amount of data to be transmitted from a terminal device, a computing unit, which calculates a bandwidth amount to be assigned to the terminal device based on the data amount, and a transmission unit, which sends the calculated assigned bandwidth amount to the terminal device. The transmission apparatus is characterized in that the computing unit calculates bandwidth amounts to be assigned to different types of flow of which different transmission qualities are requested according to a priority level that is set to each flow type. The transmission apparatus is also characterized in that bandwidth is controlled by designating, instead of a necessary bandwidth amount, transmission starting timing and transmission ending timing, particularly for fixed bandwidth communication data.
