Definitions
- TITLE Method for managing equipment within a domestic audiovisual environment, computer program, data carrier and corresponding restitution device.
- the field of the invention is that of the domestic audiovisual network, and the management of electrical consumption in such a network. More specifically, the invention relates to the management of equipment in such a network in the case where a device for reproducing a multimedia stream can be controlled remotely by several remote control devices.
- the home audiovisual network has evolved significantly in recent years, and can now integrate multiple intelligent devices, such as a television (for example a Smart TV type connected television), a TV decoder, a network access gateway Internet, a games console, or even a multimedia stream player terminal such as an HDMI key (for example the Google® Chromecast® or the Orange® TV® Key).
- Each of these pieces of equipment is provided to the user with its own remote control device, which allows it to be controlled remotely, by radio waves, by infrared, or even by wire. Furthermore, given the proliferation of equipment that can be controlled by a dedicated remote control, users are increasingly using so-called “universal” or multifunction remote controls, which make it possible to control several pieces of equipment, but also to coordinate the use of several pieces of equipment. within an activity.
- an H D M I key such as the Orange® TV® Key can, for example, be paired simultaneously with the remote control of the television to which it is connected, and with the proprietary remote control which is dedicated to it.
- remote controls can operate using various technologies (infrared, radio frequency, Bluetooth®, etc.) and, depending on this technology, have more or less significant power consumption.
- technologies infrared, radio frequency, Bluetooth®, etc.
- a standby timer for the remote controls: at the end of this timer, if no activity has been detected on the remote control, she enters automatically in standby state.
- the duration of the delay is chosen by each manufacturer, based on a comparison of the electrical consumption necessary to maintain the remote control in an active state and the electrical consumption necessary to bring the remote control out of a standby state. It also takes into account the time required to wake the remote control from a sleep state. This duration is fixed once and for all, when the remote control is built, and does not depend on its context of use. For example, for the Orange® TV Key, the duration of this “timer” (in French, delay) for putting the remote control into standby mode is set at one hour.
- the invention responds to this need by proposing a method for managing equipment within a domestic audiovisual environment, comprising a device for reproducing a multimedia stream configured to receive commands from at least two separate remote control devices.
- such an equipment management method comprises the following steps, implemented by said restitution device: detection of receipt of a command coming from a first of said remote control devices; disconnection of at least one other of said remote control devices.
- the invention is based on a completely new and inventive approach to the management of equipment in a domestic audiovisual network, and in particular remote control devices capable of controlling such equipment.
- the invention proposes, when a multimedia stream restitution device such as a TV decoder, an HDMI key or a connected television for example, can receive commands from several different remote control devices (for example a remote control dedicated to TV decoder and a remote control dedicated to the television), to disconnect at least one of these remote control devices, when it is detected that another remote control device has taken over control of the restitution device.
- a remote control dedicated to TV decoder and a remote control dedicated to the television to disconnect at least one of these remote control devices, when it is detected that another remote control device has taken over control of the restitution device.
- the user most often has a favorite remote control, which he prefers to use to control the equipment on his network, either because it is more ergonomic, or because it allows him to access more features for example. Based on this observation, it is not useful to keep active a remote control which is not used, when it is noted that the user is controlling his equipment from another remote control.
- the method according to one embodiment of the invention is based on the detection of the reception by the multimedia stream restitution device of a command coming from a remote control device, namely the remote control used by the user of the home audiovisual network: for example, the reception of key codes for changing the audiovisual reception channel coming from this remote control used is detected.
- the restitution device disconnects all or part of these other remote controls. , in order to reduce their electricity consumption. Indeed, once disconnected, these remote controls automatically switch to standby mode.
- the step of disconnecting said at least one other remote control device is implemented at the end of a time delay of determined duration, initialized upon detection of receipt of a command in coming from the first remote control device, and in the absence of reception of a command from said at least one other remote control device during the duration of the delay.
- the disconnection of unused remote control devices can be immediate, as soon as reception of a command from the remote control used is detected: in this case, the time delay is configured to be of zero duration.
- the multimedia stream restitution device receives a command from one of these other remote controls, it deduces that it is also used, and that it must therefore not be disconnected. Only those which have remained inactive for the duration of the timer can be subject to the disconnection step.
- the determined duration is chosen as a function of an objective of reducing the electrical consumption of said at least one other remote control device.
- the device for restoring a multimedia stream comprises a multimedia stream reader terminal and a restitution terminal connected to each other by an HDMI connection (“High-Definition Multimedia Interface”, in French “Interface Multimedia Haute Definition”) and compatible with the HDMI-CEC standard (“Consumer Electronics Control”, in French “control of consumer electronics”).
- said at least two separate remote control devices comprise a remote control device for the multimedia stream reader terminal and a remote control device for the playback terminal.
- HDMI-CEC is an optional function present on many HDMI compatible devices which allows you to transmit commands received from the remote control of a device to other devices connected to it by HDMI link, and therefore to control several HDMI devices from with a single remote control.
- said at least two remote control devices comply with the Bluetooth standard
- the restitution device comprises a Bluetooth server module configured to execute the step of disconnecting one of the remote control devices.
- the reproduction device is for example a connected television, to which the remote control provided by the manufacturer for this television is paired, and a multi-function remote control that the user has added to the home audiovisual network. If these two remote controls are of the Bluetooth® type, their power consumption can be high and it is therefore advisable to quickly put the one of the two that is detected not in use into standby mode.
- the invention also relates to a computer program product comprising program code instructions for implementing an equipment management method as described above, when executed by a processor.
- the invention also relates to a computer-readable recording medium on which is recorded a computer program comprising program code instructions for executing the steps of the equipment management method according to the invention as described above.
- Such a recording medium can be any entity or device capable of storing the program.
- the medium may comprise a storage means, such as a ROM, for example a CD ROM or a microelectronic circuit ROM, or even a magnetic recording means, for example a USB key or a hard disk.
- such a recording medium may be a transmissible medium such as an electrical or optical signal, which may be conveyed via an electrical or optical cable, by radio or by other means, so that the program computer it contains can be executed remotely.
- the program according to the invention can in particular be downloaded onto a network, for example the Internet network.
- the recording medium may be an integrated circuit in which the program is incorporated, the circuit being adapted to execute or to be used in the execution of the aforementioned display control method.
- the invention also relates to a device for reproducing a multimedia stream within a domestic audiovisual environment, the device being configured to receive commands from at least two separate remote control devices.
- such a restitution device comprises: a module for detecting receipt of a command coming from a first of the remote control devices; a module for disconnecting at least one other of the remote control devices.
- the disconnection module is configured to disconnect said at least one other remote control device at the end of a time delay of determined duration, initialized upon detection of receipt of a command from the first device remote control by the detection module, and in the absence of reception, by the detection module, of a command coming from said at least one other remote control device during the duration of the delay.
- such a device for reproducing a multimedia stream comprises a multimedia stream reader terminal and a reproduction terminal connected to each other by an HDMI ("High-Definition” link).
- Multimedia Interface in French “High Definition Multimedia Interface” and compatible with the HDMI-CEC (“Consumer Electronics Control”) standard.
- the detection and disconnection modules are integrated into the media stream player terminal, and the disconnection module is configured to disconnect a remote control device from the media stream player terminal when the detection module detects reception of a command coming from a remote control device of the restitution terminal.
- the aforementioned device for rendering a multimedia stream and the corresponding computer program have at least the same advantages as those conferred by the equipment management method according to the present invention.
- the invention can for example be proposed on multimedia stream reader terminals which broadcast video content (set-top-box, Chromecast® type HDMI key, Fire TV Stick, etc.), and which can be connected via HDMI to a reproduction device (e.g. a TV) with the CEC option.
- broadcast video content set-top-box, Chromecast® type HDMI key, Fire TV Stick, etc.

- the general principle of the invention is based on the disconnection of one or more unused remote control device(s) in a domestic audiovisual network, for the purposes of reducing electrical consumption, the non-use of a device remote control being deduced from the detection of the use of another remote control device.
- Figure 1 illustrates an environment for implementing the invention according to a particular embodiment.
- the environment illustrated in Figure 1 includes a DOM network of equipment audiovisual equipment of a user (telephone, TV, decoder, tablet, personal computer, games console, etc.).
- the DOM network comprises in particular:
- PAS home gateway configured to be connected to a RES communications network, for example an Internet network, and to act as a router for user terminals when they are connected to the PAS gateway.
- the PAS gateway is configured to establish a local network to which the user's domestic equipment is able to connect, for example to communicate with each other, or to access the RES Internet network.
- the PAS home gateway also provides the user with additional services such as telephony over IP (for Internet Protocol in English), television over IP, etc.
- the DEC decoder is connected to the domestic gateway to receive television streams over IP, for example wired, or wireless (WIFI), or using CPL (Power Line Carrier) technology.
- IP for example wired, or wireless (WIFI), or using CPL (Power Line Carrier) technology.
- WIFI wireless
- CPL Power Line Carrier
- the television TV1 can be a television connected, for example via WIFI, to the PAS domestic gateway.
- An RCU-TV remote control allows you to remotely control the TV1 television.
- the TV1 television can be connected to the DEC decoder via an HDMI connection, and can be compatible with the HDMI-CEC standard.
- CLETV TV key adapted to broadcast, for example, IP television streams received via the PAS gateway, from the RES network, multimedia content stored on user equipment (Computer, storage memory - not shown); the TV key is connected to the PAS domestic gateway, for example via WIFI, and plugged into an HDMI port of a TV2 television suitable for rendering decoded television streams or multimedia content.
- the TV key is, for example, compatible with the HDMI-CEC standard, and can be controlled remotely using an RCU-CLETV remote control.
- the user's home equipment network may include other home equipment not shown, for example a tablet, a personal computer, a landline or mobile telephone, Bluetooth speakers or those able to connect to the PAS home gateway, etc. . and various additional remote control devices, which may for example take the form of a voice control interface.
- a voice recognition module embedded in one of the devices, or in a remote server, analyzes the words spoken by the user and translates them into a command which is then routed to the device to be controlled.

- the user changes channels on the CLETV terminal but uses the numeric buttons on the RCU-TV remote control of the TV set to do so.
- the receipt of this channel change command in the form of a key code, is detected, during a step referenced E4, by the CLETV terminal thanks to the HDMI-CEC functionality it has on board. Indeed, this command received by the infrared receiver of the TV television is conveyed to the CLETV terminal by the HDMI cable connecting the TV television to the TV key.
- HDMI-CEC technology allows devices connected to the TV through the HDMI ports to communicate with the TV.
- the CLETV terminal integrates an order detection module, whose Operation is controlled by a daemon type computer program, which scans the key codes received and has the list of equipment in the DOM domestic environment. Upon receipt of a key code, it can identify the equipment that issued it.
- the CLETV terminal upon detection of this command received from the RCU-TV remote control, the CLETV terminal initializes a timer during a step referenced E5. This timer will preferably be of short duration D, for example one minute. During the duration D of this delay, the command detection module of the CLETV terminal scans any other key codes received, to check if another command is received from the RCU-CLETV remote control (step E6).
- step E7 End_Temp the CLETV terminal deduces that the user prefers the use of the RCU-TV remote control dedicated to the TV television rather than the use of the RCU- remote control.
- CLETV dedicated to the CLETV multimedia stream player terminal and that the latter can therefore advantageously go into standby mode, in order to save energy.
- the principle illustrated in Figure 3 is particularly advantageous in the case where the use of the RCU-TV remote control of the TV television provides the user with a more favorable service than the remote control of the RCU-CLETV multimedia stream player terminal, thanks to example to an interface including a greater number of keys or access to more varied control functions. It helps preserve the electrical energy contained in the battery of the RCU-CLETV remote control, which the user will always need for certain specific uses, and to issue certain dedicated commands, not accessible with other remote controls.
- the general principle of the invention also applies advantageously in the context of a single restitution device, for example a connected television TVC, which can be controlled by two separate remote control devices, for example a classic RCU-TVC remote control, and an RCU-SmartTV type intelligent remote control, both operating using Bluetooth® technology.
- the TVC connected television integrates a Bluetooth® server, capable of managing the connections and disconnections of the various remote controls to the TVC television.
- the user turns on the TVC television using the classic RCU-TVC remote control during a step referenced Eli.
- a step referenced E12 it sends a command to the TVC television, for example a channel change command, and uses the same RCU-TVC remote control to do this.
- the control detection module integrated into the TVC television therefore detects the preferred use of the classic RCU-TVC remote control by the user, to the detriment of the RCU-SmartTV intelligent remote control.
- the Bluetooth® server integrated into the TVC television can then immediately disconnect, during a step referenced E16, this unused RCU-SmartTV remote control, so that it goes into standby mode and thus reduces its power consumption.
- this E16 disconnection is only carried out at the end of an observation period during which it is ensured that no additional command is received from the RCU-SmartTV intelligent remote control.
- the connected television TVC initializes a time delay during a step E13, and checks, throughout the duration D of this time delay, the possible reception (step E14) of a command coming from the RCU-SmartTV remote control. .
- Disconnection E16 of the remote control to be put on standby is only carried out at the end of the time delay initialized in E13 (End_Temp step referenced E15), and on the condition that no command comes from the RCU-SmartTV remote control. was received during step E14.
- a restitution device for example the connected television TVC whose operation has been illustrated in relation to Figure 4, or the assembly constituted by the multimedia stream reader terminal CLETV and the TV restitution terminal, the operation of which has been illustrated in relation to Figure 3.
- Such a restitution device 10 is configured to receive commands from at least two separate remote control devices (not illustrated in Figure 5). He understands : a DET_CMD module for detecting receipt of commands from one or other of the remote control devices; a DCNX_RCU module for disconnecting one or other of these remote control devices.
- the restitution device 10 conventionally comprises memories M associated with a CPU processor.
- the memories can be of the ROM type (from the English “Read Only Memory”) or RAM (from the English “Random Access Memory”) or even Flash.
- It also includes an I/O input/output module that can be connected via wired or wireless 1 connection to other equipment in the home audiovisual network.
- link 1 is a wired connection of the HDMI type, or a wireless connection of the Bluetooth® type.
- the various commands received from the remote control devices are received by the I/O module.
- the restitution device 10 also includes a module for restitution of multimedia streams, denoted REST.
- This module can be a screen integrated into the restitution device 10 (for example in the case of a connected television TVC); it can also be a restitution terminal (for example a TV television) connected by an HDMI link to a multimedia stream reader terminal (for example a TV key or a decoder) integrating the other modules of the device 10 of the Figure 5.
