Patents by Inventor Jiri HALAK

Jiri HALAK has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9491333
    Abstract: The presented invention enables the reception of video signals with variable channel synchronization. All logic elements are located on the receiver side that can work with any transmitter. The receiver comprises one or more sets of modules for image processing. These sets of modules adapt the speed of sending data to the frame generator to the speed of data creation on the transmitter side without the use of a precise time pulse source on both sides of the transfer and without feedback from the receiver to the transmitter. The receiver further includes a memory of channel synchronization configuration which determines the allocation of synchronized channels to groups and the detector of starts of frames. These, along with multiplexers of clock signals, ensure the synchronization of channels within groups and allows for modifying this channel distribution.

  • Publication number: 20120327302
    Abstract: A device based on the proposed solution allows high-definition video transmissions with low latency over an asynchronous packet computer network such as Ethernet. The transmitter and receiver comprise a video input or output module, an FPGA board, and an optical transceiver for transmission and reception of a signal over the Ethernet network. The principle of the new device is that the receiver comprises one or more tunable oscillators connected to the FPGA board comprising a module for packet reception, and one or more sets of modules for video data processing.
