detailed description

A combined television provided in the present application and a video signal display method and a host chip in the startup process thereof will be described in more detail below with reference to the accompanying drawings and embodiments.

The embodiment of the present application provides a combined television, including a processor, a memory controller, a memory, a host signal source interface, a combination module, a display, and a bus. As shown in FIG. 1 , the combined television further includes:

The conversion module 101 is respectively connected to the bus 102 and the display 103 for reading the video signal of the target signal source from the memory 105 through the bus 102 with the assistance of the memory controller 104, and converting the acquired video signal into the display 103. The supported transmission mode is output to the display 103, and the target signal source is a host signal source interface or a combination module.

The memory controller 104 is connected to the bus 102, and the memory 105 is connected to the memory controller 104.

The bus 102 provides a data transmission channel for the memory controller 104, the conversion module 101, and the like.

The host signal source interface is a signal source input interface of the host of the combined TV.

In the embodiment of the present application, the conversion module 101 is respectively connected to the bus 102 and the display 103. The conversion module 101 is configured to read a video signal from the memory 105 through the bus 102 with the assistance of the memory controller 104, convert the transmission mode, and output the signal to Display 103. Since the video signal can be displayed after being converted by the transmission mode, the video signal display during the startup of the combined television can be realized by the conversion module 101.

It should be noted that the above combined television consists of a main unit, a combination part and a display part. The host of the combined television includes the above-described processor, memory controller, memory, host signal source interface, conversion module 101 and bus 102, and the like; the combination module is a combination portion; the display is a display portion. The video signal of the combination module is input into the host through the bus, and the video signal of the host is from the host signal source interface, and the conversion module 101 in the host outputs the video signal conversion mode of the combination module or the host to the display 103.

If there is no conversion module 101, the host computer of the combined TV realizes the display of the video signal of the combined module through software. Specifically, after the host of the combined TV is started, the channel switching to the combined module is completed, and the software is processed by the software. The video signal content of the combined module is displayed in the display. In this way, the display of the video signal of the combined module is realized, and the waiting time for display is long. It can be seen that if there is no conversion module 101, the display of the video signal of the combined module is implemented by the host through software switching, and the processing speed of the software switching is slow.

Thus, if there are multiple combination modules 107, only one video signal input of the combination module 107 is guaranteed.

In the embodiment of the present application, the switch module 106 is configured to strobe a combination module 107 and write the video signal of the combination module 107 into a preset position of the memory 105. Since the video signal of the combination module 107 is written to the preset position in the memory 105 and only needs to be converted into the transmission mode supported by the display 103 by the conversion module 101, the display 103 can display the video signal. Therefore, the video signal of the combination module 107 does not need to wait for the host to start up and then display it by software processing, reducing the waiting time for display. It can be seen that, in the embodiment of the present application, the display of the video signal of the combination module is implemented by the host to switch the hardware of the conversion module 101 and the switch module 106, and the hardware switching response speed is faster, compared with the manner of the software switching, waiting for display.

The video signal is read from the preset position of the video signal of the host signal source interface 109 in the memory 105 via the bus 102; if the target signal source is a combination module 107 gated by the switch module 106, the conversion module 101 is in the memory controller 104. With the assistance of the bus 102, the video signal is read from the preset position of the video signal of the combining module 107 in the memory 105.

As shown in FIG. 6, the conversion input interface 1011 includes a first conversion input interface 1013 for inputting a video signal of a host signal source interface and a second conversion input interface 1014 for inputting a video signal of the combination module.

The instructions sent by the processor 108 to the conversion output interface 1012 are sent to the conversion output interface 1012 through the conversion input interface 1011 and the converter 1010.

The conversion input interface 1011 can also be connected to the bus 102, as shown in FIG. The instructions sent by the processor 108 to the conversion output interface 1012 are sent directly to the conversion output interface 1012.

The switch module can write the video signal of the gated combined module to a preset position in the memory through the bus with the assistance of the memory controller.

In the embodiment of the present application, if there are multiple combination modules, one of the combination modules can be strobed through the switch module to ensure that only one combination module has a video signal input. Moreover, since the video signal of the combined module is written into the preset position in the memory, only the conversion module needs to be converted into the transmission mode supported by the display, and the display can display the video signal. Therefore, only the hardware such as the processor, the memory controller, the conversion module, and the switch module needs to be started to realize the display, that is, only the hardware initialization is completed, and the video signal of the combined module does not need to wait for the host to start after being processed by the software.
