Embodiment Construction

[0021] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, the TV stick 4 is connected to the second USB interface 12 of the TV, and the second USB interface 12 of the TV supplies power for the TV stick 4 when the TV stick 4 is connected, and transmits the data of the first USB interface of the TV to the TV stick 4 , so that the TV stick 4 can read the data of the external U disk through the first USB interface of the TV. The TV stick 4 is connected to the TV through the HDMI interface, so that the TV stick 4 can transmit audio and video signals to the TV and establish UART communication.

[0023] Such as figure 2 As shown, an integrated circuit of a flat panel TV and a TV stick is mainly composed of a USB switch circuit 1, a TV chip 2, a UART switch circuit 3 and a TV stick 4, and the USB switch circuit 1 is electrically connected to the TV chip 2 , the TV chip 2 is electrically connecte...

Abstract

The invention discloses a flat television and Dongle integrated circuit, which mainly comprises a USB switch circuit, a television chip, a universal asynchronous receiver / transmitter (UART) switch circuit and a Dongle. The USB switch circuit is electrically connected with the television chip. The television chip is electrically connected with the UART switch circuit. The Dongle is electrically connected with the television chip through the UART switch circuit. The invention also discloses a control method. The control method comprises the steps that the television chip gives out a control signal so as to control the USB switch circuit and the UART switch circuit, then whether the Dongle is accessed is detected, and on and off of a USB switch and on and off of a UART switch are realized through the control signal. The flat television and Dongle integrated circuit has the beneficial effects that the flat television and Dongle are integrated, and the port and functions of the television are guaranteed not to be affected while the Dongle is not accessed.

Description

technical field [0001] The invention relates to the technical field of flat-panel TVs, in particular to an integrated circuit and control method for flat-panel TVs and TV sticks. Background technique [0002] In the current domestic consumption concept, flat-panel TV is a kind of durable consumer goods. The development of technology has made the processing speed bottleneck of the TV core more and more prominent with time, and an external TV stick is a convenient and economical way to solve this problem. The traditional TV stick and the TV core are two completely independent systems. The user needs to use a mobile phone or a dedicated remote control to operate the TV stick, and the TV stick is limited in size. It needs to be powered by a power adapter and an external U disk must use an adapter cable. Beautiful and inconvenient. Contents of the invention [0003] The present invention overcomes the problem of inconvenient installation, use and reading of the USB flash driv...
