20110043690 | Signal transmission system - A signal transmission system includes a transmission apparatus and a reception apparatus, the transmission apparatus including: a first portion that converts a video signal into differential signals, converts a vertical synchronization signal into a common mode signal, and transmits the converted signals to the reception apparatus via three pairs of signal lines; and a second portion that converts a horizontal synchronization signal into differential signals, converts a first console signal into a common mode signal, transmits the converted signals to the reception apparatus via a single pair of signal lines; the reception apparatus including: a third portion that restores the differential signals to the video signal, and restores the common mode signal to the vertical synchronization signal; and a fourth portion that restores the differential signals to the horizontal synchronization signal, and restores the common mode signal to the first console signal. | 02-24-2011 |
20110063502 | DEVICE AND METHOD FOR SYNCHRONIZING AN INTERACTIVE MARK TO STREAMING CONTENT - The present invention concerns a device and a method for inserting an interactive mark in a streaming content, said method comprising the steps of receiving a streaming content in a first format, receiving the same streaming content in a second format, receiving an interactive mark, corresponding to a first frame of said content in a first format and sending said interactive mark synchronized to a second frame of the content received in the second format, the content in said second frame corresponding to the content in said first frame. | 03-17-2011 |
20110255001 | VIDEO SIGNAL PROCESSING DEVICE, VIDEO SIGNAL PROCESSING SYSTEM, AND VIDEO SIGNAL PROCESSING METHOD - In a video signal processing device, a host CPU sets a number of parameters for a memory table at its low-load timing such as during power-up. The host CPU then enables the function of an automatic setting controller. Being notified of start of automatic setting, the automatic setting controller reads plural clock setting parameters from the memory table, and performs clock setting in a clock generation section while waiting for stabilization of PLL oscillation. The automatic setting control section then reads plural signal processing parameters from the memory table and sets the parameters in a video signal processing section. Thus, in operation of the video signal processing section and the clock generation section according to the format of the input video signal, it is possible to set a number of setting parameters in these sections while reducing the load of the host CPU, shortening the image output time. | 10-20-2011 |
20130033642 | DATA TRANSMISSION ACROSS INDEPENDENT STREAMS - Various systems and methods are provided for transmission of related data components across independent streams. In one embodiment, among others, a transmitting device may separate transmission data into related data components and transmit each related data component in an associated transport stream. Each related data component includes a synchronization tag associated with synchronization of the related data component within the transmission data. In another embodiment, a receiving device may receive related data components transmitted in separate transport streams and decode the related data components based at least in part upon a synchronization tag included in each related data component. In another embodiment, among others, a method for includes receiving data components transmitted on a plurality of transport streams, separating related data components from unrelated data components in the transport streams based at least in part upon a synchronization tag of each related data component; and decoding the related data components. | 02-07-2013 |
20150116594 | Pixel clock generation circuit and method thereof - This invention discloses circuits and methods for generating a pixel clock. The circuits utilize an image signal of a first format to generate a pixel clock, which can be utilized to generate an image signal of a second format. The circuits include a reference clock generation circuit, an image processing circuit, and a clock adjustment circuit. The reference clock generation circuit generates a reference clock. The image processing circuit processes the image signal of the first format to generate a control signal. The clock adjustment circuit, which is coupled to the reference clock generation circuit and the image signal processing circuit, generates the pixel clock according to the reference clock and the control signal. The control signal is substantially a periodic signal, whose frequency is proportional to the frequency of a synchronization signal of the image signal of the second format. | 04-30-2015 |
20150296101 | Universal Film mode detection for interlaced video stream - A universal film mode detection method is presented here which is capable to detect different cadences like 3:2, 2:2, 32322, 4:4 and etc. The film mode detection is based on searching for moving “Sandwich” patterns in the merged adjacent fields. The number of “Sandwich” patterns and amplitude of “Sandwich” patterns are accumulated across the whole field which will be used to determine the film mode. A vertical symmetric “Sandwich” pattern detector is used to avoid different result in ODD and EVEN fields. This improved film mode detection method can provide reliable result for deinterlacer which is used to improve the vertical resolution in interlaced video during converting to progressive. The same structure with different threshold can also provide information for temporal interpolator which can be used to remove judder effect by increasing the frame rate. | 10-15-2015 |
