There is disclosed one or more methods, systems and components therefor for broadcasting captions of a presenter's speech to audience members to accompany the live viewing of the presentation. A host captioning device converts the presenter's speech to text and communicates the text to and for presentation by an audience member's client device. The communication session between the host captioning device and the client device is established by an invitation request from the host captioning device in response to a registration request from the client device. The captioning information may be communicated in real time as text. The host captioning device either connects to a network or provides one itself, thereby serving as an access point for the client devices.

A method for discovering a communication device is disclosed. The method includes: receiving in the communication device a communication including a request for an address and an identification of an application, in response to receiving the communication, associating a dynamic address of the communication device with the identified application, and sending a second communication directly or indirectly to a client device, the second communication including the dynamic address. The communication device may further obtain a dynamic address in response to receiving the communication. The dynamic address may be used for a dedicated purpose, such as for receiving a file for subsequent use by the application.

A computing device is disclosed having two or more perimeters, where each perimeter is a logical separation of computing resources. A computing device and method are also disclosed for generating a data audit trail for data transfers between two perimeters.

Generating a data audit trail for cross perimeter data transfer

A system for relaying data based on a modified reliable transport protocol is provided. According to an aspect, a relay can receive a data packet sent in accordance with a reliable transport protocol. The relay processes the received packet in accordance with modified reliable protocol and relays the received packet. The modifications can be based on alterations to reliability mechanisms which improve communication characteristics of the protocol for real time communications and other time sensitive communications. The modified protocol is nevertheless compatible with the original reliable protocol so that relay can communicate, using the modified protocol with any network component using the unmodified protocol.

A token used when a first device authenticates itself to a third device may be associated with a token issue timestamp. Upon receipt of an indication that all previously issued tokens are to be revoked, a second device may store a revocation timestamp. Upon receiving, from the second device, a request for establishing conditions for a file transfer, from the first device, and an indication of a token issue timestamp associated with the request, the second device may compare the token issue timestamp to the revocation timestamp. Responsive to determining, based on the comparing, that the token issue timestamp precedes the revocation timestamp, the second device may deny the request.

Timestamp-based token revocation

A wireless device is provided. The wireless device has a processor for controlling operation of the wireless device; a first input device coupled to the processor for accepting an input; at least one display device coupled to the processor for communicating an output to the user; a communications subsystem coupled to the processor for communicating with a communications network; a universal serial bus (USB) storage device connected to a USB port of the wireless device; a memory coupled to the processor; and a storage device coupled to the processor. The wireless device includes a USB/network handling module resident in the memory for execution by the processor. The USB/network handling module is configured to establish a secure connection between the wireless device and a server of a network; load a universal serial bus mass storage component; initiate a file share between the wireless device and the server; and mount the USB storage device connected to the USB port of the wireless device as a shared network drive on the network.

Aspects relate to machine recognition of human voices in live or recorded audio content, and delivering text derived from such live or recorded content as real time text, with contextual information derived from characteristics of the audio. For example, volume information can be encoded as larger and smaller font sizes. Speaker changes can be detected and indicated through text additions, or color changes to the font. A variety of other context information can be detected and encoded in graphical rendition commands available through RTT, or by extending the information provided with RTT packets, and processing that extended information accordingly for modifying the display of the RTT text content.

Determining and conveying contextual information for real time text

Techniques for use in controlling data traffic in a wireless local area network (WLAN) which includes at least one access point (AP) are described. In one illustrative example, the terminal is associated with the AP and receives data traffic from a source device via the AP. The terminal identifies whether a processing requirement of the terminal for processing data traffic exceeds a predetermined threshold. In response to such identifying, the terminal produces a control message which includes a source address corresponding to the source device and a destination address corresponding to the terminal, and sends the control message to the AP. The control message is defined to instruct the AP to prohibit transmission of the data traffic originating from the source address and destined to the destination address. In one scenario, the control message further includes a time value indication, for instructing the AP to prohibit transmission of the data traffic only for a time period indicated by the time value indication.

A method for monitoring use of a mobile hotspot function in a wireless device, comprising: storing a last access time for a client within a memory of the wireless device, the last access time being a time when the hotspot function last performed a network address translation for the client; determining whether a difference between a current time and the last access time exceeds a threshold; and, if the difference exceeds the threshold, generating an indication that the mobile hotspot function is not in use by the client.

Example methods and apparatus to manage wireless device power consumption are disclosed. In accordance with a disclosed example method a data frame exchange is initiated with an access point of a wireless network. In response to not successfully completing the frame exchange with the access point, the access point is designated as providing the wireless terminal with fringe wireless signal coverage.
