[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In the prior art, a set-top box needs to include interface circuits such as HDMI, Ethernet, and power supply, and requires a dedicated remote control, which has the problems of high cost and large size. In order to overcome the above problems, the present application proposes a set-top box that can effectively meet the high bandwidth requirements of ultra-high-definition video transmission, while reducing the number of interfaces, reducing costs, and achieving lightweight equipment.

[0037] The present application embodiment discloses a set-top box 10, see Figure 1 As shown, the set-top box may include a universal multimedia interface circuit 11 and a processor 12 .

[0038] The universal multimedia interface circuit 11 includes a universal multimedia interface chip and a peripheral circuit; the universal multimedia interface circuit 11 is connected to the processor 12; the universal multimedia interface chip is connected to the universal multimedia interface chip of the television;

[0039] The universal multimedia interface chip is used to decompose the signal sent by the universal multimedia interface chip of the television, and forward the decomposed signal to the processor; the signal includes a remote control signal and network data; the universal multimedia interface chip is used to obtain the voltage transmitted by the television;

[0040] The processor 12 is used for data processing.

[0041] The set-top box contains a general purpose multimedia interface (GPMI), which can support extremely high data transmission rates and integrate functions such as video, audio, data streaming and power transmission. GPMI can reach up to 144Gbps, significantly exceeding the current 48 Gbps of the HDMI2.1 interface, and can easily handle the transmission of 8K120FPS ultra-high-definition video data streams. At the same time, GPMI supports up to 480W power supply and network communication rates of gigabit and above. In addition, GPMI supports technologies such as the Advanced Digital Content Protection (ADCP) content protection protocol to provide a safe and high-quality multimedia experience.

[0042] Current set-top boxes generally have HDMI, USB, RJ45 Ethernet, and power interfaces. For set-top boxes based on the GPMI interface, only the GPMI interface needs to be reserved. The GPMI audio and video transmission channel replaces the HDMI or DP display interface, which can easily meet the current ultra-high-definition video transmission needs; in addition, the GPMI interface includes USB interfaces such as Type-B and Type-C, which can share the TV USB interface and remove the USB interface of the set-top box.

[0043] The GPMI interface circuit includes a GPMI interface chip and peripheral circuits. The interface circuit is responsible for GPMI interface power supply protocol negotiation, power supply negotiation with the TV GPMI interface chip, and determining the power supply voltage level. At the same time, it has the function of converting HDMI / DP display signals and audio signals into GPMI ultra-high-definition audio and video signals. In addition, the interface chip can distinguish data signals and decompose GPMI channel data signals into specific application data, such as remote control signals, network data, basic transmission data, etc., reducing the data processing capacity of the processor (such as CPU). The CPU is responsible for operating system operation, audio and video decoding, system control, encryption and decryption, storage management, network communication and other functions.

[0044] Furthermore, the universal multimedia interface chip is used to negotiate power supply with the universal multimedia interface chip of the television, and to accept the voltage output by the power supply unit of the television through the universal multimedia interface chip of the television after the negotiation is passed; the universal multimedia interface chip of the television is used to negotiate power supply with the universal multimedia interface chip of the set-top box after detecting that a powered device including the universal multimedia interface chip is connected; the power supply negotiation includes power supply mode and power supply voltage, and the power supply mode includes single power supply and multi-power supply. That is, by using the power supply feature supported by GPMI, the power supply requirements of current mainstream devices can be basically met, so the use of the power interface can be eliminated, and the need for a set-top box power adapter is also eliminated. For example Figure 2 As shown, first, the set-top box is connected to the TV through the GPMI interface. The TV GPMI interface chip will perform plug / unplug detection. After detecting that the GPMI powered device is connected, power supply negotiation is performed. According to the power demand of the set-top box, it is determined whether it is single power supply or dual power supply, and the power supply voltage level is specified. Finally, the TV interface chip controls the TV power module to output the corresponding voltage according to the negotiated power supply information to complete the power supply of the device.

[0045] The set-top box also includes a power supply unit; the power supply unit is connected to the general multimedia interface circuit and is used for voltage conversion and power supply. The power supply unit is connected to the GPMI interface power supply signal and is responsible for converting the power provided by the GPMI into different voltage levels required by the set-top box; if the GPMI interface power supply negotiation is abnormal, the GPMI interface chip can control it to shut down the power supply.

[0046] Furthermore, the universal multimedia interface chip is used to receive the remote control signal sent by the TV and forward the remote control signal to the processor; the remote control signal is sent by the control device received by the TV through the wireless receiving module on the TV side, the wireless receiving module on the TV side is used to forward the remote control signal to the processor on the TV side, the processor on the TV side is used to decode the remote control signal, and if it is determined that the remote control signal is for the set-top box, the remote control signal is sent to the universal multimedia interface chip of the set-top box through the universal multimedia interface chip on the TV side. For example Figure 3 As shown, the set-top box and the TV reuse control devices such as remote controllers or game controllers, and use Bluetooth or low-latency, high-reliability Star Flash wireless technology to transmit remote control commands to the TV CPU. The TV CPU decodes the received remote control signal and identifies whether the signal is used to control the TV or the set-top box. If it is identified as a control signal of the set-top box, the corresponding control command is transmitted to the CPU of the set-top box through the GPMI interface, thereby realizing the control of the set-top box.

[0047] Furthermore, the universal multimedia interface chip is used to receive network data sent by the TV and forward the network data to the processor; the network data is the Ethernet signal received by the TV from the external Ethernet converted into a USB signal and then forwarded to the set-top box. Figure 4 As shown in the figure, the RJ45 interface of the TV is connected to the external Ethernet, and then the Ethernet signal is converted into a USB3.0 signal, which is transmitted to the CPU through the GPMI interface for network data access. The GPMI interface includes the Type-C interface function, and uses the USB3.0 channel for network data transmission. Since the USB3.0 transmission rate supports 5Gbps communication, which is far higher than the current 1Gbps of the Gigabit network, it can achieve Gigabit and above network access.

[0048] Furthermore, the set-top box also includes an indicator light; the indicator light is connected to the processor and is used to indicate the operating status of the set-top box. The indicator light mainly indicates the operating, standby and abnormal status of the set-top box. For example, when the set-top box is operating normally, it will display green; when the set-top box is on standby, it will display orange; when the set-top box has a fault, it will display red.

[0049] Furthermore, the universal multimedia interface chip is used to receive the upgrade data sent by the TV, and forward the upgrade data to the processor so that the processor can perform version upgrade based on the upgrade data; the upgrade data is read by the TV from an external device connected to the TV, or read from an upgrade server through the network interface of the TV. Figure 5 As shown in the figure, the new set-top box has two modes: local upgrade and online upgrade. Local upgrade is performed through the USB interface of the TV. First, store the correct software upgrade package in the USB peripheral, then insert the USB peripheral into the USB interface of the TV, and then operate the set-top box to select the operating system software upgrade package in the USB peripheral for local upgrade. For online upgrade, operate the set-top box to select network online upgrade, and receive the operating system software upgrade package sent by the upgrade management server through the network channel for upgrade.

[0050] For example Figure 6As shown in the figure, the new set-top box consists of a GPMI interface circuit, a processor, a power supply unit and an indicator light. The set-top box communicates with the network through the data transmission channel of GPMI. The Ethernet signal on the TV side is converted into a GPMI data signal, which is then transmitted to the set-top box to achieve network access. Therefore, the use of Ethernet circuit components such as the Ethernet chip and RJ45 socket of the set-top box can be reduced; the TV remote control transmits the remote control command to the set-top box through the GPMI data channel, and the set-top box executes the relevant commands to achieve the remote control operation of the set-top box by the TV remote control, thus reducing the number of remote controls. Integrating interfaces such as USB and Ethernet on the TV, while retaining the core and fast-growing audio and video decoding part in the set-top box, is conducive to reducing the cost of users replacing set-top boxes, promoting the development of set-top boxes in the direction of miniaturization and lightweight, and also meeting users' needs for the simplicity and beauty of smart home appliances.

[0051] As can be seen from the above, the set-top box in this embodiment includes a universal multimedia interface circuit and a processor; the multimedia interface circuit includes a universal multimedia interface chip and a peripheral circuit; the universal multimedia interface circuit is connected to the processor; the universal multimedia interface chip is connected to the universal multimedia interface chip of the TV; the universal multimedia interface chip is used to decompose the signal sent by the universal multimedia interface chip of the TV, and forward the decomposed signal to the processor; the signal includes a remote control signal and network data; the universal multimedia interface chip is used to obtain the voltage transmitted by the TV; the processor is used for data processing. It can be seen that the universal multimedia interface chip can realize power reuse, which is powered by the TV, and the set-top box does not need a power interface and a power adapter; remote control reuse can be realized, the set-top box and the TV share a remote control, and the TV sends the remote control signal to the set-top box; network reuse can be realized, the set-top box accesses the TV network through the universal multimedia interface chip, and the set-top box does not need an Ethernet circuit and a network interface; thus, a universal multimedia interface can effectively meet the high bandwidth requirements of ultra-high-definition video transmission while reducing the number of interfaces, reducing costs, and realizing lightweight equipment.
