- the present invention relates to a multimedia device for receiving audiovisual broadcasts which can, for example, be connected to a personal computer.
- the audiovisual reception multimedia device can, for example, consist of a decoder or any other device that can be connected to a two-way cable network.
- This return channel will be used for interactivity functions between the user of the decoded audio video program and the operator of the television network.
- the current digital decoders to be in conformity with the European standard in force, present a standby mode with low consumption. This state is reached when only the functions essential for waking up the multimedia device are supplied. For example, the decoder then in standby mode must be able to be awakened, in order to record a television program on a video recorder.

- a switching circuit the multimedia device from a first mode of operation, called standby, in which the communication circuit has the minimum of active functions towards a second mode of operation, called an alarm clock, in which the communication circuit has its communication function, between the connector and the audiovisual network, activated, the switching being consecutive to the appearance of the bus supply voltage.
- the connector is a client connector (11) of the USB (Universal Serial Bus) type.
- the switching circuit is constituted by a first microprocessor of a means for controlling the multimedia device and a program for triggering the wake-up actions constituting the wake-up sequence of the communication circuit.
- control means is a control keyboard and / or a remote control receiver for said device. multimedia, said control means being connected to an interrupt input of said first microprocessor.
- the detection means are connected to an interrupt input of the first microprocessor receiving the detection signal.
- the first microprocessor is connected to a general supply circuit of the multimedia device to activate said supply circuit in response to the appearance of the detection signal.
- the detection means consist of an electronic switch generating a voltage on one of the inputs of the first microprocessor.
- said apparatus comprises a digital television decoder, said communication circuit comprising a circuit for connection to a bidirectional cable network.
- said device comprises an interface circuit adapted to the type of connector connected to the internal bus of the digital decoder connecting a main processor of the decoder to a return channel processor of the digital decoder, said return channel processor being connected , by an interface circuit to a cable connecting to the bidirectional cable network connecting the digital decoder to the service of the audiovisual operator's server.
- said device includes means for triggering the connection to the Internet through the service of the server of the audiovisual operator.
- FIGS. 1 and 2 show a schematic view of the alarm device according to the invention
- - Figure 2 shows a schematic view of the integration of the wake-up device into a decoder and the communication of this decoder with on the one hand a personal computer and on the other hand the cable of the audiovisual broadcast network.
- FIGS. 1 and 2 A nonlimiting embodiment of the invention will now be described with FIGS. 1 and 2.
- a personal computer (17), portable or not, is connected by a cable (16) of the USB (Universal Serial Bus) type to a USB connector (11) forming part of a decoder (20).
- the computer (20) here plays the role of master of the USB bus.
- the computer is used here as an example of a source device, but any other electronic device requiring a connection to an Internet network can also be used.
- the decoder (20) is given by way of example of a multimedia device with reduced operating mode, but the invention can be applied to any other type of multimedia device for receiving audiovisual broadcast.
- the decoder (20) is connected to a specific cable for digital television (14) which allows, through a service from the operator's server (21), connection to the Internet through the service from the operator's host center 21 audio-visual.
- the advantage of such a system is to allow:
- This link is permitted with a minor modification of the multimedia device, in the example given, of the decoder.
- This minor modification consists in integrating into the decoder a USB connector (11) whose input terminal (VBUS) is connected to a circuit (1) for detecting the VBUS voltage (i.e. the supply voltage of the USB bus generated by the master).
- This circuit (1) belongs to a USB interface circuit (9), which is connected to the input terminals (DATA +, DATA-) and to the ground of the USB connector (11).
- the output of the detection circuit (1) is connected by a link (2) to an input interrupting a microprocessor (3) which is the microprocessor of the decoder keyboard and the front panel.
- This microprocessor is connected by a link (4) to the main power circuit (5) and by an I2C bus (12) to the main processor (7).
- the main power supply supplies the main microprocessor (7).
- This microprocessor (3) is the only one in the decoder to be permanently active, even when the decoder returns to standby mode. It suffices that the decoder socket is connected to the power supply network. In fact, in standby mode, only this microprocessor continuously monitors its inputs to detect signals processed as interruptions representing: either a signal from the keyboard on the front of the decoder constituting an interruption for the microprocessor, or a signal, product by the photoreceptor (19) connected by a link (18) to the microprocessor (3), linked to the transmission of a command using the remote control by the user.
- the invention is also used to detect an interruption linked to the detection of the connection of a USB connector.
- the microprocessor can continuously monitor its digital inputs (polling) to detect changes in the states of the inputs and carry out the desired processing.
- the decoder In its operation, the decoder, when it detects by its microprocessor (3) an interruption, sends a signal by the link (4) on the main power supply of the whole of the decoder which then feeds (link (6)) the main processor (7) for awakening the functionalities of the decoder necessary for the commanded function.
- This functionality will allow the recording of a TV program on the video recorder or the viewing of a channel received by the decoder on the television or the use of the decoder as a modem.
- the main processor (7) dialogs with a bus (15) for transporting audio and video signals, digital and the stage (13) of RF reception of the decoder which is connected by a drop cable (14 ') to the cable (14) input-output of the decoder.
- this will be sent by the link (12) of the I2C bus connecting the processor (3) of the front panel to the main processor (7), which will process the information and dialogue with the processor (10), through the processor bus (8) which connects it to the return channel processor (10).
- This processor (10) is connected by an output interface to the cable (14) to allow interactivity between the operator and the user by transmission and reception of digital data.
- the keyboard or front panel microprocessor (3) is associated by its processor bus (31) with a memory, which contains a program module (30) which manages the interruptions appearing on the lines (18) to trigger, according to these interruptions, the awakening of the entire decoder.
- the embodiment of the invention consists in adding, in addition to the detection circuit (1), a line (2) at the output of the circuit (1) for detecting the VBUS voltage, this line being sent to an interrupt input.
- high level of the microprocessor (3) to trigger the execution of a program module (32) performing the processing of this interruption and performing, firstly the sending by the line (4) of a wake-up signal from the main power supply (5) of the decoder then via the I2C bus (12), the sending of a command to the main processor (7), so that this dialogs with the microprocessor (10) of the channel return through the processor bus (8) and to put the latter on standby for the arrival of signals on its bus (8) coming from the interface card (9) of the USB connector (11).
- the role of the interface circuit (9) will be to transform the protocol for exchanging USB signals between the personal computer (17) and the interface circuit (9) into a communication protocol compatible between the two processors (10) return channel and (7) main via the bus (8).
- the VBUS terminal of the connector As can be seen in Figure 1, the VBUS terminal of the connector
- USB is connected to a common point (100), which is connected on the one hand through a resistor (101) to ground and on the other hand to the base of a PNP transistor (106).
- the PNP transistor has its collector connected to ground and its emitter connected to the common point (107) and to a resistor (105), the second end of which is connected to the voltage supply point VCC.
- the last common point (107) delivers the signal for detecting the presence of the voltage VBUS on the line (2) which is connected to the highest level interrupt input of the microprocessor (3) of the front panel.
- the other elements of Figure 2 are identical to those of Figure 1 and are designated by the same references.
- the interface part (9, 10) of the decoder operates in slave mode with respect to the personal computer (17), which means that control signals for interactive television functions from the remote control are either temporarily deactivated by the main processor (7) and a display controlled by this processor (7) indicates to the user that the interactivity function is interrupted following a connection to the Internet , or the microprocessor (7) performs a multiplexing of these signals with those from the personal computer (17).
- the USB interface (9) incorporates an identifier into the signals from the USB bus and the main microprocessor (7) also incorporates into the signals from the remote control a different identifier allowing the service (21) of the operator to distinguish between the signals from the personal computer (17), intended for the Internet link and those intended to produce modifications of the services delivered, coming from the remote control. So the computer automatically wakes up the decoder by activating the voltage on the USB bus, which makes it possible to prepare for communication via the wired network.
