Apparatus for updating content of television internal USB storing equipment

Abstract

The equipment renovates the content of USB storage equipment inside TV set and the said TV set relates to one player, one inside USB storage equipment connecting with the player and one extended USB interface. The USB interface connects with the said player and USB storage equipment by data line, and the USB interface connects with one USB interface of computer. There are one inverter (U1B) and one switching tube (Q2) between the PC-VCC of the USB interface to computer and USB-VCC of USB storage equipment. There are one inverter (U1A) and one switching tube (Q1) between the MAIN-VCC of the said player and USB-VCC of USB storage equipment. The equipment can quickly renew the content of the USB storage equipment inside TV set with sample renovating operation.

Description

【Technical field】 [0001] The invention relates to a device for updating data of a built-in storage device, in particular to a device for quickly updating data of a built-in USB device through a USB interface. 【Background technique】 [0002] With the development of digital multimedia technology and digital TV broadcasting technology, TV receivers are changed from analog TV to digital TV. The digital processing circuit that digital TV must have realizes the mutual compatibility between digital TV and other digital products. The current digital TV can not only passively receive TV signals, but there are some TVs with built-in storage devices (such as USB devices or IDE hard disks), such as advertising machines placed in shopping malls and office buildings, which have the function of information storage. . [0003] At present, a TV set with a built-in storage device mainly includes a built-in USB storage device, a player, an external USB device interface, and electronic compone...

AI Technical Summary

Problems solved by technology

If the computer is used to update the content of the built-in USB storage device through the USB interface of the TV set, since the power supply end of the player, the power supply end of the built-in USB storage device, and the power supply end of the computer USB interface are directly connected, the computer and the player are the same. The source of power supply, if the two voltages are inconsistent, or if one is turned off, the current of the computer or player will flow to the other party, affecting the normal operation of the other party's system, or even damage the other party.

Therefore, nowadays, it is generally used to turn on the TV, remove the built-in USB storage device, update its data through the computer, and then reinstall it to the TV. This way the update speed is fast, but the operation is troublesome.

There is also a method to update the content of the built-in USB storage device. Use the data update function of the player itself to copy and paste the new content to the built-in USB storage device through its USB interface. This is easy to operate, but the update function of the player itself is limited. , and its USB interface copy speed is too slow, not very practical
