Description

A high-definition digital set-top box with mobile hard disk function

technical field

The utility model relates to a high-definition digital set-top box with the function of a mobile hard disk. the

Background technique

With the rapid development of high-definition digital TV, set-top boxes are rapidly entering thousands of households as digital high-definition receiving terminals. Visual effects have become a trend. The current high-definition set-top boxes are generally not equipped with hard disks, and only a few PVR set-top boxes have their own hard disks. This makes it impossible for users to bookmark their favorite programs and share them with others, and even those models equipped with hard drives can generally only record TV programs on the TV network and store them on the hard drive for later playback. The function of its built-in hard disk is limited to storing and playing the programs uploaded and uploaded from the digital TV network, and it cannot copy the user's favorite video programs from the computer like a high-definition player and store and play them. the

Contents of the invention

The utility model aims at the above problems, and develops a high-definition digital set-top box with a mobile hard disk function. The technical means adopted in the utility model are as follows:

A high-definition digital set-top box with a mobile hard disk function, comprising: an embedded multimedia processor for comprehensive control of the set-top box, a tuner module for decoding data on the TV network and a power supply module for supplying power to the entire set-top box; it is characterized in that Including: the USB interface used to connect the set-top box to the computer; connect the USB interface and the embedded multimedia processor, and convert the data received by the USB interface to a USB-SATA conversion module; connect the USB-SATA conversion module to convert the USB-SATA The built-in hard disk that stores the data converted by the conversion module and the data decoded by the tuner module; connect the power module, USB interface and USB-SATA conversion module, and control the power supply module to supply power to the USB interface and USB-SATA conversion module to realize USB The interface and the working mode control circuit controlled by the USB-SATA conversion module; the connection mode of the above-mentioned modules is data connection, and the power supply module is connected with each functional module through wires. The working mode control circuit includes a single-chip microcomputer GPIO control circuit for judging whether the USB interface is connected to the computer through a USB cable, and the GPIO pins of the single-chip microcomputer GPIO control circuit are connected to the level pins of the USB interface. the

Compared with the prior art, the utility model adds a USB-SATA conversion module and a working mode control circuit to the high-definition digital set-top box, and the audio and video program data that the user likes can be copied from the computer for playback through the USB interface, and can also be The program data in the hard disk is copied to the computer to share with others, which means that the built-in hard disk of the set-top box can be used as a mobile hard disk. In addition, its structure is simple, easy to produce, and its cost is very suitable for wide promotion. the

Description of drawings

The utility model has a drawing:

FIG. 1 is a schematic structural diagram of the set-top box described in the present invention. the

Detailed ways

As shown in Figure 1, this high-definition digital set-top box includes an embedded multimedia processor 1 (CPU), a tuner module 2 (i.e. a tuner), a power supply module 3, a USB interface 4, a USB-SATA conversion module 5, a built-in hard disk 6, and a working mode Control circuit 7, wherein the operating mode control circuit includes a single-chip microcomputer GPIO control circuit 8. Wherein the embedded multimedia processor 1 is connected to the tuner module 2, the USB interface 4 is connected to the USB-SATA conversion module 5, the USB-SATA conversion module 5 and the hard disk 6 are connected by the SATA bus, and the USB-SATA conversion module 5 acts as a USB conversion SATA role. The power supply module 3 is respectively connected with other modules to provide power supply for each module, and it is controlled by the working mode control circuit 7 . The working mode control circuit 7 includes a single-chip microcomputer GPIO control circuit 8, which is connected with the power supply module 3, the USB interface 4, and the USB-SATA conversion module 5 respectively. the

The specific work process is as follows: in the case of shutdown, the power supply module 3 stops supplying power to each module. At this time, the GPIO pin of the single-chip microcomputer GPIO control circuit 8 detects the level pin of the USB interface 4, and judges whether the USB interface 4 is connected by a USB cable. When the set-top box is connected to the computer, the single-chip microcomputer GPIO control circuit 8 immediately controls the power supply module to supply power to the USB-SATA conversion module 5 and the built-in hard disk 6, and enables the USB-SATA conversion module 5 to realize data exchange between the hard disk 6 and the computer. Change, the set-top box hard disk will be used as a mobile hard disk at this time. In the case of starting up, the single-chip microcomputer GPIO control circuit 8 controls the power supply module 3 to supply power to the remaining modules except the USB-SATA conversion module 5. At this time, the embedded multimedia processor 1 receives data from the tuner module 2 and stores the decoded program data to the internal hard drive. Even if the set-top box is connected to the computer at this time, the single-chip microcomputer control circuit 8 will also ignore the signal on the level pin of the USB interface 4, so that the USB-SATA conversion module 5 is in a non-working state. the

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Any equivalent replacement or change of the new technical solution and its inventive concept shall be covered by the protection scope of the present utility model. the
