A “communications rate controller” provides various techniques for maximizing a quality of real-time communications (RTC) (including audio and / or video broadcasts and conferencing) over multi-hop networks such as, for example, the Internet. Endpoints in such networks generally communicate via a segmented path that extends through one or more routers between each endpoint. Maximization of conferencing quality is generally accomplished by providing in-session bandwidth estimation across segments of the network path between endpoints (i.e., communication / conference participants) in combination with a robust non-oscillating dynamic rate control strategy for maximizing usage of available bandwidth between RTC endpoints. Further, the dynamic rate control techniques provided by the communications rate controller are designed to prevent degradation in end-to-end delay, jitter, and packet loss characteristics of the RTC.

A method and apparatus for deriving performance statistics from real time tracking of a sporting event. The method according to the present invention includes a step of obtaining a spatio-temporal trajectory corresponding to the motion of an athlete and based on real time tracking of the athlete. The trajectory is then broken down so that performance information corresponding to the motion of the athlete (such as speed, distance covered, acceleration, etc.) can be derived with respect to time. The information so obtained can be stored in a database or the like for later retrieval or can be used to graphically supplement a video broadcast of a sporting event. The apparatus includes a device for obtaining the trajectory, a computational device for obtaining the performance information based on the obtained trajectory, and a statistical device for compiling the performance information. In particular, the spatio-temporal trajectory may be obtained by an operation on a video image of the sporting event, in which motion regions in the image are identified, and feature points on the regions are tracked as they move, thereby defining feature paths. The feature paths, in turn, are associated in clusters, which clusters generally correspond to the motion of some portion of the athlete (e.g., arms, legs, etc.). The collective plurality of clusters corresponds with the motion of the athlete as a whole.

A video recording device includes the ability to record a video broadcast or video program while concurrently replaying a previously recorded video broadcast. This previously recorded video broadcast can be the same video broadcast that is recording or a different video broadcast. The record and playback operations are preferably triggered and controlled through a television on which the user can watch the playback of the recorded program. The viewer enters the data and commands for recording and playback preferably using a remote control device. Video programs are preferably recorded on a mass storage device. Preferably, the mass storage device is a hard disk drive coupled to the television through an IEEE 1394 serial bus network. Alternatively, any other appropriately configured memory device can be used to store the video programs. The television uses write commands to transmit to and record the program onto the mass storage device and read commands to retrieve previously recorded portions of a program to be replayed from the mass storage device. When playing back a previously recorded program or the recorded portions of a program which is still being recorded, the television will retrieve the packets of data from the mass storage device in sequence, using read commands to read from the appropriate locations where the appropriate packets have been stored. Each packet is then retrieved in sequence from the beginning of the program, even if the end portion of the program is still being recorded.
