The present invention provides a system that creates virtual events within a virtual world. A virtual event may be akin to a real event, but is completely computer generated within a computer-generated world and is based on statistical measures, either real world or created. Numerous characteristics about the competitors and the competition location parameters are available before a competition event. Based on the known parameters about the location of an event and the characteristics of the participants and their historical past performances in similar events enable bettors to make informed wagers on an event that greatly enhances the satisfaction and involvement in a competition event. As such, Histories of virtual events are maintained on actual virtual performance data of competitors in the virtual world. The histories can include all relevant virtual data about a competitor and the past events the competitor competed.The virtual event may be created by an event engine, scheduled, and broadcast or simulcast in real-time through-out the real-world using existing and conventional video transport media, such as web, TV, satellite, telephone network, and cable. A video delivery system is used that will allow high quality high definition video to be broadcast worldwide with very low bandwidth requirements (<20 kb / s).Individuals throughout the real-world may place wagers (e.g., bets) on the outcome of either a pari-mutuel event or a fixed odds event, utilizing either pari-mutuel, exchange wagering or fixed odds wagering systems. The virtual event may be any type of sport, or skill based game that is usually between competitors.

A system and method for improving a surgeon's vision by overlaying augmented reality information onto a video image of the surgical site. A high definition video camera sends a video image in real time. Prior to the surgery, a pre-operative image is created from MRI, x-ray, ultrasound, or other method of diagnosis using imaging technology. The pre-operative image is stored within the computer. The computer processes the pre-operative image to decipher organs, anatomical geometries, vessels, tissue planes, orientation, and other structures. As the surgeon performs the surgery, the AR controller augments the real time video image with the processed pre-operative image and displays the augmented image on an interface to provide further guidance to the surgeon during the surgical procedure.

The consistency callback mechanisms employed by local file systems such as NTFS and distributed file systems such as DDS, NFS and CIFS are extended to provide a shared memory foundation for efficiently broadcasting real-time high definition video from a source object to large numbers of viewers via the Internet. Distributed applications such as video viewing client applications establish connections to a common distributed file system object, and then each application registers with the underlying distributed file system to receive notifications whenever the video source modifies the source object. The data required to update images maintained by viewing clients is included in notification messages. The distributed file system employs a network of proxy cache nodes. Proxy cache nodes receive notification messages (complete with image update data) and update their cached images of the source object and then retransmit the notification messages towards the viewing clients using IP multicast techniques. In this manner, the distributed file system's consistency mechanism efficiently employs network resources to enable the real-time distribution of video content streams.

Additionally, each sub-block can be implemented independently with localized interconnection so that parallelism can be exploited and a much higher DCT / IDCT throughput can be achieved.

An adaptive digital image processor precedes an MPEG2 encoder. The processor receives a high definition video signal intended for broadcast or storage, and adaptively low-pass filters the signal. The signal is subjected to low-pass two-dimensional filtering to eliminate encoding artifacts and related noise. The video signal is then horizontally down-sampled to create a lower resolution hybrid signal. A receiver decodes and decompresses the hybrid signal. The hybrid signal is upsampled to its original resolution using existing hardware and software with a software modification.
