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.

An implementation of streaming video in HTML (Hypertext Markup Language) Web pages combines video signals in MPEG digital television format with Internet World Wide Web pages in HTML format. Internet streaming video is transcoded into MPEG-2 digital video format and multiplexed along with other MPEG-2 digital video signals for transport within a multiple channel digital video system. A navigational control map, transmitted from the headend to the CATV set-top box in a fixed location i n the MPEG-2 video data steam, permits the CATV set-top to find the requested video clip in a predetermined Packet Identifier of the MPEG-2 data stream. The viewer controls the video clip (e.g., play, pause, resume, restart etc.) during the session. In the two-way embodiment, the set-top transmits control commands to the headend, which implements the command in MPEG-2 video. The disclosed arrangement allows the available MPEG-2 decoder hardware in the CATV set-top box to be used to display streaming video without requiring additional hardware or additional RAM memory.

A scalable video transmission scheme is provided in which client interaction and video content itself are taken into consideration during transmission. Methods and arrangements are provided to prioritize / classify different types of information according to their importance and to packetize or otherwise arrange the prioritized information in a manner such that lower priority information may be dropped during transmission. Thus, when network congestion occurs or there is not enough network bandwidth to transmit all of the prioritized information about an object, some (e.g., lower priority) information may be dropped at the server or at an intermediate network node to reduce the bit rate. Thus, when the server transmits multiple video objects over a channel of limited bandwidth capacity, the bit rate allocated to each object can be adjusted according to several factors, such as, e.g., information importance and client interaction.

Various embodiments of the invention provide novel apparatus, methods and systems for providing relatively high-speed bandwidth to enable, inter alia, video transmission services over media previously unable to support such services. In accordance with certain embodiments, a device located at the telecommunication service provider can logically couple two or more physical media to provide a single, consolidated source of bandwidth, which can be used to transmit data, which can represent a video signal. In accordance with other embodiments, a device located at the subscriber's location can be used to receive the data from each of the two physical media and recreate the video signal from the data, such that the video signal can be transmitted to a display device, such as a television, monitor, etc.

Described herein are systems and methods for multiplexing and transmitting video data. The systems and methods use excess bandwidth in a channel available after meeting minimum transmission requirements for all bitstreams. A network device of the invention flexibly allocates this available bandwidth to minimize further rate reduction. More specifically, the network device periodically determines the available bandwidth, and divides the available bandwidth among multiple incoming bitstreams being multiplexed in order to increase downstream decoder buffer levels. By maintaining increased decoder buffer levels, future rate reduction of the video data may be avoided or applied to a lesser degree. Minimizing rate reduction in this manner improves bandwidth usage efficiency, and thus improves video data transmission and end-user output video quality.

A method and apparatus for creating a trick play video display from an MPEG-2 digital video transport stream are described. A trick play transport stream frame sequence template for each transport stream frame sequence and trick play video display mode supported by a video recorder is stored in the recorder. When the recorder receives an input transport stream frame sequence, the sequence is identified and template corresponding to that sequence and the selected trick play display mode is selected. The template is used to identify frames of the input transport stream to be appended to the trick play display transport stream frame sequence. When the trick play transport stream frame sequence is constructed the program clock reference, presentation time stamps and decoding time stamps associated with the frames are updated from information in the template.
