Abstract

The method for distributing video streams performs a simultaneous and continuous capture of different video sequences, which are converted as they are captured into streams of digital video data continuously transmitted in multipoint distribution from one transmitter to at least two remote mobile terminals personal to a user, via a telecommunication network. At the level of each terminal, the streams are received and an interface for controlling their distribution is displayed. The interface permits each user to select one video sequence for viewing at the level of his terminal as well as to control the distribution of viewing by streaming at actual speed, or by changing the frame rate, and/or by choosing the direction of streaming, and/or by selecting a moment of the sequence.

Claims

1. A method for distributing digital data streams to spectators during events onsite, said spectators also being onsite, the method comprising the steps of:

performing a simultaneous and continuous capture of at least two separate video sequences, each separate video sequence being converted while being captured into a respective digital stream of digital data;

continuously transmitting the digital streams in multipoint distribution from at least one transmission terminal to at least two mobile terminals, located at a distance, each termina being personal to a user, via a telecommunication network; and

receiving the digital streams at the level of each terminal and displaying an interface for controlling distribution;

wherein each interface for a respective user permits selection of video sequences for viewing at the level of a respective terminal and controls distribution of said viewing by streaming at actual speed, or by stopping, slowing down, accelerating the frame rate, and/or by choosing the direction of streaming, and/or by selecting a moment of said sequence;

wherein each stream is temporarily stored in a buffer of a circular type, at a level of internal memory of each terminal; and

wherein each stream stored in said buffer after a time interval determined with respect to a duration defined for each video sequence is continuously deleted, said time interval corresponding to a duration from several minutes to several tens of minutes.

2. The distribution method according to claim 1, wherein said time interval corresponds to a duration from 10 to 20 minutes.
