• the aforementioned additional information data can be received from the terminal (STB) for playback by the playback device (TV).
• TER user equipment
• SER management server
• the service order registration signal can be generated by the management server
• the command recording signal is in reality aimed at a pre-recording of the command, and this command is finally recorded only after validation by the user.
• the equipment (TER) can receive from the management server (SER) (or even a server managed by a service provider) an order confirmation request to be validated via for example a touch screen of the equipment. (TER).
• the equipment (TER) can present on a screen a list of services whose command is to be confirmed and the user can choose to validate one by one by pressing on the touch screen the various services offered to him.
• the SER management server can be a single server for the implementation of the various steps above or be connected to other servers (managed by the advertiser, by the service provider, and / or others), thus forming a “server entity” in general (also called “platform” in the detailed description which follows).
• the aforementioned comparison of the timestamps to choose the timestamp corresponding to the timestamp of generation of the control signal, and the determination of the service identifier corresponding to the chosen timestamp, at least, are carried out by the server management (SER).
• SER server management
• the server (SER) interrogates the terminal (STB) receiving the stream to retrieve the timestamps of the sequences programmed in the stream, and to perform the aforementioned comparison.
• the server can query a third-party server (SERA) making available a publication of the timestamps of the programmed sequences, with the corresponding identifiers, this third-party server (SERA) being able to be maintained by an advertising agency of a broadcasting channel TV, for example.
• SERA third-party server
• the comparison of the timestamps to choose the timestamp corresponding to the timestamp of generation of the control signal, and the determination of the service identifier corresponding to the chosen timestamp are carried out by the terminal (STB), and this terminal (STB) transmits to the management server the service identifier corresponding to the chosen timestamp.
• This embodiment can be advantageous in particular in the case where simply a remote control button is pressed by the user to control the terminal (STB) instead of providing a voice assistant type HMI interface.
• the terminal (STB) which performs the comparison between the timestamps of the sequences it receives and that of the event of pressing the remote control button, until it can thus retrieve the identifier of the service whose sequence has nearest timestamp and send that service identifier to the server (SER).
• HMI voice assistant type interface
• the aforementioned stream of multimedia data (F) can typically be a stream of television or radio data, broadcast in real time (or slightly delayed), or even in rebroadcast or “replay” (or else a broadcast data stream, recorded for example on a personal recorder (or “PVR”) and replayed).
• PVR personal recorder
• this stream may appear advertising spots corresponding to the aforementioned sequences containing information relating to respective services.
• the expected broadcast time of these sequences (in real time relative to an instant at which data was sent from a station head end, or even deferred with respect to an instant at the start of reading of the stream) is known. and a timestamp can thus be associated with each sequence and thence with each service identifier corresponding to this sequence.
• the terminal can play a list (“playlist”) of several video streams often comprising a sequence of N streams starting with one or more advertising sequences and continuing with content.
• a device configured for, with a view to ordering a service and following:
• multimedia content comprising a plurality of sequences containing information relating to respective services, at respective times of reproduction of the content
• the terminal receiving, in addition to multimedia data, data:
• Such a device can be a management server (SER) which, as indicated above, can be configured to implement steps of the above method and more particularly the aforementioned comparison of the timestamps to choose the timestamp corresponding to the timestamp of generating the control signal, and determining the service identifier corresponding to the selected timestamp.
• SER management server
• such a device can be a terminal (STB) for receiving a stream (F) of multimedia data, configured to implement steps of the above method and more particularly the comparison of the timestamps to choose the corresponding timestamp. at the time stamp of generation of the control signal, determining the service identifier corresponding to the time stamp chosen, and transmission to the management server of the service identifier corresponding to the chosen timestamp.
• STB terminal
• F stream
• a system for controlling a service comprising at least:
• a reproduction device connected to the terminal, for reproducing multimedia content corresponding to multimedia data, said multimedia content comprising a plurality of sequences containing information relating to respective services, at respective times of reproduction of the content,
• a man-machine interface available to a user for generating a command signal for a service, the sequence of which may be being restored by the device, and transmitting the command signal with a time stamp for generating the command signal, and a user reference,
• a management server able to process the service control signal with a view to recording a service order for this user
• the terminal is arranged to receive, in addition to the multimedia data, data:
• the terminal and the management server is designed to:
• a computer program comprising instructions for the implementation of all or part of a method as defined. herein when this program is executed by a processor.
• a non-transient, computer-readable recording medium on which such a program is recorded.
