LOS ANGELES, March 22, 2012 /PRNewswire/ -- ICAP Patent Brokerage, a division of ICAP plc and the world's largest intellectual property brokerage firm and organizer of ICAP Ocean Tomo Auctions, is offering for auction patent portfolios from Siemens that improve voice and video interface, networking efficiency, and network security from Siemens Aktiengesellschaft. The lot will be included in the 15th ICAP Ocean Tomo IP Auction on March 29, 2012, at Terranea Resort near Los Angeles, California.
Key Characteristics & Benefits
Two patent portfolios disclose an improved solution for handling video and voice calls and improved techniques for network efficiency and security using improved protocols:
The first portfolio discloses a technique for monitoring the multiple channels provided by a digital line (e.g., ISDN).
- When an incoming call is received while channels are in use, the user is asked to select a priority choice between the incoming and the already established call.
- If the established call is selected, the incoming call is forwarded to a messaging system.
- If the incoming call is the priority choice, then a channel is made available to receive this call.
- Thus, the interface of video and voice calls is improved.
The second portfolio discloses techniques for enhanced network security and efficiency:
- Techniques for security of data transmission in the network.
- Data to be transmitted is split into smaller packets (e.g., separate characters) and sent to a destination through various routes to prevent interception.
- Further, the packets are numbered and sent in a pseudo-random sequence to prevent a third party from assembling the data even if a large percentage of data packets is intercepted.
- Techniques for improving data transfer efficiency in a network.
- An aggregate packet is built from smaller packets for data transmission.
- The original or small packets are transmitted in case the media or port is available before complete construction of the aggregate packet. Otherwise, the aggregate packet is sent.
- Data transfer efficiency is improved.
Techniques for using a network access protocol (Carrier Sense Multiple Access with Collision Detection (CSMA/CD)) for allowing isochronous data flow in a network.
- Periodic time slots can be reserved for isochronous transmission of data in a network.
- When non-isochronous transmissions are desired, the transmission is performed by using CSMA/CD protocols and taking into account the already reserved time slots.
These are key strategic portfolios for companies providing data processing and network communication devices, services, and systems.
