A signal processing apparatus includes: an inputting section inputting plural video signals; a signal processing section subjecting the plural video signals; one or more sub-multiscreen split display signal generating sections selecting P (P: integral number of 2 or more) kinds of video signals from the plural video signals subjected to the signal processing, and intermediate generation signals as one or more video signals generated while the signal processing section subjects the plural video signals to the signal processing, and synthesizing the P kinds of video signals, thereby generating one or more sub-multiscreen split display signals; and a multiscreen split display signal generating section selecting Q (Q: integral number of 1 or more) kinds of sub-multiscreen split display signals from the one or more sub-multiscreen split display signals, and synthesizing the Q kinds of sub-multiscreen split display signals, thereby generating a multiscreen split display signal.

Signal processing apparatus and method, and program

Disclosed herein is a video processing apparatus for performing video processing compatible with a dual link progressive scheme, said video processing apparatus including: two video processing circuits; and a control section.

Video processing apparatus and video processing method

A digital signal switching apparatus is provided. The digital signal switching apparatus inputs and outputs digital signals to which status information formed of a block including a plurality of frames is added. The digital signal switching apparatus includes: a retrieving unit configured to retrieve the status information from the digital signal to which switching processing was performed; a storing unit configured to store one or more blocks of the status information retrieved by the retrieving unit; and an adding unit configured to add again the status information stored in the storing unit by the block to a position of the status information in the digital signal to which the switching processing was performed.

Digital signal switching apparatus and method of switching digital signals

A video apparatus for processing an input video signal in synchronization with an external reference signal is provided. The video apparatus includes a phase compensation FIFO memory and a measuring device. The phase compensation FIFO memory is configured such that the input video signal is written in synchronization with a clock demodulated from the input video signal and the video signal is read in synchronization with an internal reference clock of the apparatus generated from the external reference signal. The measuring device is configured to measure an amount of jitter/wander of the input video signal based on a calculation of a difference between data volume of the video signal obtained in the FIFO memory and a predetermined reference volume.

Video apparatus and method of measuring jitter/wander

A signal switching apparatus includes: a video reference input block; a plurality of synchronous signal generating blocks; a plurality of video signal input blocks; a signal processing block; a video signal output processing block; a switching block; and a control block.

Signal switching apparatus and control method of signal switching apparatus

A sampling frequency conversion apparatus having sampling frequency conversion circuits for a plurality of channels includes a detector detecting phase information of digital signals inputted to the conversion circuit for each channel, and an input section inputting setting information for the conversion circuits for two or more channels to be phase-synchronized. The apparatus further includes a phase information supplier supplying the phase information for the conversion circuit for a specific channel designated by the setting information inputted into the input section to the conversion circuits for the remaining channels of those for two or more channels other than the conversion circuit for the specific channel, and a sampling frequency converter performing sampling frequency conversion on the phase information of the conversion circuits for the remaining channels in synchronization with the phase information for the specific channel supplied from the phase information supplier.

Sampling frequency conversion apparatus and signal switching apparatus

This invention provides a matrix switcher apparatus adapted to arbitrarily distribute signals in a plurality of input channels to a plurality of output channels. The matrix switcher apparatus includes a cross point matrix adapted for connecting one matrix switcher unit to any other matrix switcher unit or units to carry out expansion of input/output, and input and output terminals expandable up to a predetermined maximum number of channels. Further, this invention provides a matrix switcher apparatus comprising a first cross point matrix including a first group of input terminals to receive signals in a plurality of channels, and a first group of output terminals for at least some of the plurality of channels and a second group of output terminals for expansion to any other unit or units; and a second cross point matrix including a second group of input terminals coupled with the first group of output terminals and a third group of input terminals for receiving signals from one or more additional matrix switcher apparatus for expansion, and a third group of output terminals fewer in number than the plurality of channels, thereby making it possible to construct a matrix switching system on a compact scale or in any of a variety of scales, and to reduce its cost.
