A system and a methodology to improve the end-user quality of service both in terms of response time and reliability for the transport of in-call DTMF signals in wireless systems, particularly in geostationary mobile satellite systems. The methodology encompasses several techniques to provide acceptable end-to-end quality of service for DTMF. A technique is applicable for transport of DTMF in the wireless subscriber to network direction, where DTMF digits are carried in the form of an out-band message. The central part of the technique is to allow multiple key presses in the same message, thereby increasing efficiency and throughput in long-delay environment. Another technique utilizes the vocoders functionality to carry DTMF in-band, thereby reducing system complexity. The scheme makes the use of an integrated DTMF detector which can classify a given frame of signal into several classes so that the DTMF encoded packet can carry a unique pattern across the air-interface to the voice decoder at AT, which is capable of identifying the pattern. Another technique pertains to the use of a message based DTMF transport between two-ATs on a separate logical channel with a unique Service Access point Identifier (SAPI) providing guaranteed service for DTMF transport in an AT-AT call.

Non-standard broadcast television signals are processed and converted for proper reception and display. Extra or missing horizontal lines are processed using modulo or digital phase lock loop-type circuit to change clock output signal proportionately according to a difference determined by comparing a standard video signal value with an actual input signal line count value, such that modified clock output signal serves as a clock input signal for circuit accepting standard video format. Non-standard video signal having improper odd-even field sequencing is also processed and converted.

A method, a system and recording medium for maintaining the order of nodes in a hierarchical document. The method may select the maximum and the minimum number of children for each node, build an auxiliary ordered tree having at least as many leaves as atoms within the hierarchical document based upon the selected maximum and minimum number of children for each node, attach the atoms to the leaves of the auxiliary ordered tree, and label each of the nodes in the auxiliary ordered tree.

In a distributed network having a number of server computers and associated client devices, method of isolating infected client devices from uninfected client devices is described. The method is carried out by correlating network related virus infection information, determining if a virus outbreak has occurred based on the correlated information, isolating infected client devices from uninfected client devices when the virus outbreak is confirmed, monitoring all data packets in the network for the virus, identifying a packet type associated with the virus, and blocking only the identified packet type.

A network level virus monitoring system capable of monitoring a flow of network traffic in any of a number of inspection modes depending upon the particular needs of a system administrator. The monitoring provides an early warning of a virus attack thereby facilitating quarantine procedures directed at containing a virus outbreak. By providing such an early warning, the network virus monitor reduces the number of computers ultimately affected by the virus attack resulting in a concomitant reduction in both the cost of repair to the system and the amount of downtime. In this way, the inventive network virus monitor provides a great improvement in system uptime and reduction in system losses.
