A monitor camera photographs a whole monitor area for capturing the photographed whole monitor area as high definition image data higher in resolution than a display screen. A new object detection / extraction unit detects a new object in the monitor area based on the high definition image data captured by the monitor camera, extracts partial image data of an area, which contains the new object, from the high definition image data, and obtains location information on the partial image data in relation to the high definition image data. A whole-monitor-area image data down-sampling unit down-samples the high definition image data to produce standard definition image data corresponding to the resolution of the display screen. An image enlargement unit enlarges the standard definition image data based on entered enlargement instruction information. An image combination unit overlaps the partial image data on image data, enlarged by the image enlargement unit, based on the location information and sends resulting image data to the display screen.

A system and method for testing radio coverage of a land mobile radio system. The system configuration generally employs a fixed unit, a mobile unit and the two-way radio system (not part of the invention) subject to testing. The test system and method are compatible with any land-mobile radio system (conventional, trunked, using proprietary or standards-based protocols, FDMA or TDMA) operating in any frequency band. One of three methods may be selected to perform testing at any one time: continuous testing, grid testing or receive-only testing. In the continuous and grid modes, both the talk-out and talk-in paths are measured. Test results are recorded in a computer file after being converted to a digital format, and are compared to an original “reference file” via the Perceptual Evaluation of Speech Quality (PESQ) algorithm as defined by ITU-T standard P.862. The PESQ output is then converted to a Delivered Audio Quality (DAQ) score by application of an empirical set of weighting factors to certain of the PESQ parameters.

A multi-camera high-definition or standard-definition switched video signal is distributed from the Point of Capture (POC) using industry standard technology for broadband distribution such as fiber optic or satellite, to a Point Of Display (POD) where multiple video projectors or displays integrated with a digital light show and high-end audio are utilized to provide a totally immersive entertainment environment. That environment is controlled using a graphically based tool called the LightPiano™, and is then extended through the festival atmosphere in the Club Annex, where licensed merchandise, auctions, and swap meets are located. Online Instant Messaging, Short Message System (SMS) text messaging, Chat, and Fan Clubs generate additional content, which is sent back to the POD. There is extensive use of the Worldwide Web for both local and remote access to the chat, fan clubs, SMS and instant messaging systems, as well as for online access for customers to view scheduling, and purchase ticketing, webcasts and archive access. The Web is also used by the venue owner to manage the entire system for booking, data mining, scheduling, ticketing, webcasting, and facilities management. The Web interface combined with the power of the LightPiano makes this complex interrelated system relatively easy and intuitive to operate. It significantly lowers the cost of operation and makes the system scalable to a large network of POCs and PODs. It allows one POC to feed many PODs, enabling a truly global distributed, immersive entertainment environment.

The invention relates to upscaling of images such as upscaling of video images from standard definition to high definition. An input image is upscaled to a resolution enhanced image (207) by weighting pixel values in the input image depending on a match metric combining two match metrics. A first image generator (103) generates a blurred version of the input image and a second image generator (103) generates an upscaled 5 interpolated version. The first metric is generated bycomparing pixel sets of the blurred image and the upscaled interpolated image. A second metric is generated by comparing pixel sets of the input image and already synthesized pixel values of the resolution enhanced image (207). For each location in a search area, a resolution enhancement processor (107) generates the combined match metric and uses this to weigh the pixel value of that location when 10 generating the unknown pixel value of the resolution enhanced image (207).
