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 displaying still video images related to video content in an interactive broadcast television system. The system and method of the present invention may also be used for simulating an Internet home page on an interactive television system. The present invention thus supports hyperlinked web-like navigational capabilities in an interactive television system. According to the method of the present invention, the video delivery system provides or broadcasts one or more audio / video channels each comprising video content and also provides or broadcasts at least one still image channel comprising a plurality of still video images, preferably MPEG-2 compressed still images. The user or viewer can select options displayed on the television screen to view desired information. When the set top box receives user input selecting an option to view one of the linked still images, the set top box captures the requested image from the still image broadcast channel, stores the image in memory, and displays the captured still video image corresponding to the selection. The still image being displayed may have associated interactive program content for displaying further selections, wherein these selections may be for viewing other images or content, for ordering information, or purchasing products. The user can thus selectively navigate between the video content and stills in a web-like hyperlinked fashion. In one embodiment, when a user is navigating through still images, the television program or video content which was being viewed is displayed in a small window overlaid on the still image being displayed. Also, when the set top box captures a requested image from the still image broadcast channel, the set top box preferably also pre-caches or pre-loads other related still images based on the probabilty that these related images will be subsequently requested by the user. The invention also includes an embodiment which provides user requested still images "on demand" on a dedicated "search" channel.

A system and a method are disclosed for delivering a video to a destination device using multiple sources and multiple protocols. The video can be on demand or a live video. A video is divided into several chunks distributed across devices and servers in the network. A node is selected for delivering a video chunk based on criteria including the cost of delivery of the chunk from the node to the destination node. This also improves the throughput of the entire system. Different nodes can use different communication protocols for delivering chunks of videos. Portions of videos are forward-cached to a node before a request for the video is made by the node. Activities associated with a device are gathered to determine a profile for the device. The profile of the device is used to select videos to be forward-cached to the peer device.

During times of congestion, the multiplexer will discard packets from its internal queues. Packets are intelligently chosen to minimize the effects on the output from the receivers (22) by taking into account timing information related to the packets and priority.

A circular buffer in a video delivery server tracks a second copy of a live video stream to provide instant replay capability. When an end-user initiates the instant replay function, the circular buffer is copied to an instant-replay buffer, from which a replay of the video is sent to the end-user. During replay the end-user can use playback functions such as pause, slow-play, freeze frame, etc. Upon leaving the replay function the end user rejoins the live stream. The circular buffer also enables transmission of delayed copies of the live stream, time-shifted by predetermined intervals, which copies are multicasted to end-users. Upon request, an end-user may join a delayed version of interest. This allows the user to replay interesting content by jumping to a time-delayed version without missing the show and to catch up with real-time during e.g. commercial breaks.

Adaptive video encoding based on predicted wireless channel conditions. Based on at least one of a number of transmitter side indications of the available throughput of a wireless channel for video delivery, an encoder rate adaptation mechanism generates an estimate of the supportable throughput of the wireless channel under different operating conditions. An encoding parameter, such as encoder bit rate, is subsequently altered based on the estimated throughput value. In one instance, transmitter side throughput indicia is used to generate target encoder bit rates for multiple potential PHY data rates / channel MCS selections that may be used in video delivery. In anticipation of or immediately following a transition to one such PHY data rate / MCS selection, the encoder bit rate is altered in accordance with an associated target bit rate. In another mode, average transmit queue latency information is used to further regulate the encoder bit rate.
