20100208714 | WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION APPARATUS, WIRELESS COMMUNICATION METHOD, AND COMPUTER PROGRAM - Random access operation is performed under a communication environment in which a plurality of communication modes having different transmission rate coexist with small overhead. A high-grade communication station spoofs information of a packet length and a rate in a decoding portion so that a value of (packet length)/(rate) corresponds to a duration where the communication is hoped to be stopped. The other station receiving the spoofed information receives the rest of the packet with the designated rate during the interval designated by the value of (packet length)/(rate). In this case, the packet length and the rate are not those of actually transmitted packet so that this packet is discarded. | 2010-08-19 |
20100208723 | SYSTEMS AND METHODS FOR NETWORK FACSIMILE TRANSMISSIONS - Disclosed herein are systems and methods for sending and receiving facsimile transmissions in a voice-over-IP system.

20100208724 | Power Savings For Network Telephones - In an example embodiment, an IP phone is connected to a network switch that has an established communications channel to a call control server.

20100208808 | Apparatus and Method for Coding an Information Signal into a Data Stream, Converting the Data Stream and Decoding the Data Stream - More customization and adaptation of coded data streams may be achieved by processing the information signal such that the various syntax structures obtained by pre-coding the information signal are placed into logical data packets, each of which being associated with a specific data packet type of a predetermined set of data packet types, and by defining a predetermined order of data packet types within one access unit of data packets. The consecutive access units in the data stream may, for example, correspond to different time portions of the information signal. By defining the predetermined order among the data packet types it is possible, at decoder's side, to detect the borders between successive access units even when removable data packets are removed from the data stream on the way from the data stream source to the decoder without incorporation of any hints into the reminder of the data stream. Due to this, decoders surely detect the beginnings and endings of access units and therefore are not liable to a buffer overflow despite a removal of data packets from the data stream before arrival at the decoder. | 2010-08-19 |
