The present invention provides a method and bypass device of IP allocation based on the network, the method comprising: establishing a mapping relation between the parameters of a visitor and an IP address; filing a request for visiting the network using the parameters of the visitor; performing authentication of AAA according to parameters of the visitor; finding the IP address corresponding to the successful parameters of the visitor from the mapping relation between the parameters of the visitor and the IP address and allocating the found IP address via DHCP to the network terminal being used by the visitor, to achieve the allocation of IP address based on the parameters of the visitor. The problem of the determination of the true identity of the visitor is solved and the safety of the network and the reasonable allocation of the network sources are improved. Other on-line or off-line devices are set using the IP address section correspond to the parameters of the visitor and thus, making these devices to realize the existing functions of the network devices according to the parameters of the visitor.

There is provided an apparatus and method for performing unique word detection and frequency offset estimation for a receiver for DPSK signals comprising in-phase I and quadrature Q components for a plurality of symbols k. The apparatus comprises: a differential detector for performing differential detection of a received signal over a given symbol span; a frequency corrector for performing an initial correction of I and Q using a previously estimated value of the frequency offset; accumulators for averaging I and Q for each symbol k over a given number K of symbols, where K is the number of symbols in the unique word to be detected; a frequency offset estimation block for calculating an estimate of the frequency offset from averaged I and averaged Q; and a unique word detection block for determining, from differentially detected I, differentially detected Q, averaged I and averaged Q, whether or not the unique word is present in a received signal.

A backlight includes a light source and one or more light recycling films. The light source generates light that exits the light source with an angular exit distribution. The light recycling films are oriented in relation to the light source so that the prism peaks of the recycling films are oriented away from the light source. The recycling films have a range of optimal incident angles that allow light to pass through the recycling films without recycling. The components of the light source, the characteristics of the recycling films, or both, are configured to control the overlap between the exit distribution of the light source and the optimal incident angle range of the recycling films.

A method and apparatus for allocating time slots in a baseband EPCN system is provided. The method includes: obtaining a period type of a current period; and determining a proportion between uplink time slots and downlink time slots for the current period according to the period type. According to present invention, different proportions between uplink time slots and downlink time slots may be respectively applied to different periods such as a registration period and a communication period in the baseband EPCN system. Thus, the register time of a new CNU in the registration period is shortened and the requirement for high downlink bandwidth for normal communications in the communication period is guaranteed at the same time.

Automated wireless three-dimensional (3D) video conferencing is provided using a tunerless television device. A 3D video conference is automatically established with a wireless device capable of 3D video conferencing using a wireless communication interface of the tunerless television device. A first and a second two-dimensional (2D) video stream are received, using a camera interface module, from a first and a second video camera associated with the tunerless television device. A merged 3D video stream is created from the first 2D video stream and the second 2D video stream using a 3D video offload processing module operatively coupled to the camera interface module. The merged 3D video stream is sent to the wireless device using the wireless communication interface. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

Embodiments of the present invention provide a data transmission method, a Coaxial-Cable Network Unit (CNU) and a Coaxial-cable Line Terminal (CLT). The method is applied to a point-to-multipoint Coaxial-cable Network, wherein the point-to-multipoint Coaxial-cable Network includes a Coaxial-cable Line Terminal, CLT, and a plurality of Coaxial-Cable Network Units, CNUs; the CLT shares transmission medium with the CNUs. The method includes: obtaining, by the CLT, an uplink receiving scrambling code, and decrypting, by the CLT, with the obtained uplink receiving scrambling code, data sent from a CNU after being encrypted with an uplink transmission scrambling code; and obtaining, by the CNU, a downlink receiving scrambling code, and decrypting, by the CNU, data received by the CNU with the obtained downlink receiving scrambling code; wherein the uplink receiving scrambling code is different from the downlink receiving scrambling code. In embodiments of the present invention, the CNU includes a scrambling code obtaining unit, a decryption execution unit and a data interaction unit. The CLT includes a scrambling code processing unit, a decryption execution unit and a data interaction unit. With the embodiments of the present invention, the security of the uplink data transmission in an Ethernet Passive Coaxial Network (EPCN) system is guaranteed, and the QoS of services is greatly enhanced.

A 3D video conferencing system includes two cameras at each of two video conferencing locations. Images from the two cameras are exchanged between the locations and are combined at the receiving location in accordance with the angle at which the viewer at the receiving location is viewing an otherwise 2D display to give the illusion of depth perception.
