A video delivery apparatus for delivering a video stream with a property according to a request from a client. The video delivery apparatus includes reception means for receiving a delivery request from one client, first estimation means for estimating a current processing load by calculating a sum total of the processing loads for other clients connected to deliver a video stream upon reception of the delivery request from the one client, second estimation means for estimating a processing load upon delivering the video stream to the one client according to the delivery request, and delivery control means for performing the delivery control of the video stream on the basis of at least one of the current processing load estimated by the first estimation means and the processing load upon delivering the video stream to the one client according to the delivery request, which is estimated by the second estimation means.

Video delivery apparatus and method

A wireless LAN system is configured using a communication apparatus for a wireless LAN including an antenna unit comprising an antenna, or an antenna and at least a part of a circuit of the system provided as one body, and a support for supporting the antenna unit. In addition, a pedestal for the support configured so that a terminal device for transmission or reception can be disposed thereon.

Communication apparatus for a wireless local area network

The present invention relates to a spread spectrum signal reception apparatus for receiving a code division multiplex signal, and for receiving a spread spectrum signal for synchronization previous to the code division multiplex signal. The reception apparatus detection means for detecting a reception level of the spread spectrum signal for synchronization previous to the code division multiplex signal, and adjustment means for adjusting a level of the code division multiplex signal in accordance with the reception level detected by the detection means.

Spread spectrum signal reception apparatus

A spread spectrum receiving apparatus is constructed by a generator for generating a reference clock, a phase shift circuit for shifting the phase of the reference clock generated by the generator in accordance with a code timing in a reception signal and the reference clock, and a de-spreading circuit for de-spreading the reception signal in accordance with the reference clock whose phase is shifted by the phase shift circuit. The de-spreading circuit generates a code for de-spreading in accordance with the phase shifted reference clock. The phase shift circuit has a calculator for calculating a phase shift amount so as to synchronize the code timing in the reception signal with the code for reception in accordance with a deviation between the code timing in the reception signal and the reference clock.
