System and method for selective image capture, transmission and reconstruction
View Patent ↗A video processing method and system for generating a foveated video display with sections having different resolutions uses a network channel for communicating video images having video sections of different resolutions, and includes a video transmission system for processing and transmitting the received video images over the network channel. The system assigns a larger portion of the network channel's bandwidth to a video section with higher resolution. Further, the system includes a video receiving system for receiving and seamlessly combining the first and second video sections of different resolutions to form an output video image on a display device, and a control unit for sending one or more video control parameters to the video transmission system to control capturing, transmitting and processing of the video images.
1. A digital, modular video data processing system for the capture, transmission, reception, and reconstruction of video image data over a network, the system comprising:
an input image processing module for sampling and packetizing video images received from an image-capture device;
a network transmission module and a network receiving module for transforming data of the video images to match at least one of a plurality of network protocols, and a first communication channel for coupling the network transmission module and the network receiving module;
a first image processing module, coupled between the input image processing module and the network transmission module, for compressing the video images received from the input image processing module prior to transmission, wherein the first image processing module transmits a first region in the video images at a higher resolution than a second region in the video images by allocating a larger portion of a bandwidth of the first communication channel to the first region;
a second image processing module, coupled to the network receiving module, for de-compressing the compressed video images received from the network receiving module;
an output image processing module, coupled to the second image processing module, for processing, depacketizing and reconstructing the video image data;
a second communication channel coupled between the network receiving module and the network transmission module for selectively controlling selection of the first region in the video images through one of user and software instructions and for communicating user-defined image capture and video processing parameters for transmission and display of the video images; and
a plurality of digital data communication channels for coupling at least one of a plurality of additional image processing modules to the first and second image processing modules for modular scaling of image processing and for providing parallel processing of portions of the video images.
