In practice, since the CI card 120 is a separate sheet-like unit, the adapting unit 30 can mount the CI card 120 on the adapting unit 30 by providing a slot sheet-like matching the CI card 120, and also facilitate replacement of the CI card 120. In addition, in practical application, since the CI interface 111 may be a fixed standard thimble type plug, and the adaptor unit 30 is further configured to be connected to the CI interface 111 in a plug-in manner, the adaptor unit 30 may further implement the plug-in connection with the CI interface thimble type plug by setting a thimble jack corresponding to the CI interface 111.
Fig. 2 shows a schematic structural diagram of a switching unit in a television motherboard CI interface detection device according to an embodiment of the present application. As shown in fig. 2, as an embodiment of the present application, the transit unit 30 includes: the CI card slot 31 and the CI connection terminal 32. Specifically, the method comprises the following steps:
the CI card slot 31 is used for plugging and connecting the CI card 120; the CI connection 32 is used for plug connection to the CI interface 111.
As a possible implementation manner of the present embodiment, the CI card slot 31 comprises a first wall slot 311, a second wall slot 312 and a CI card connector 313, when in use, the CI card 120 is slid into the CI card slot 31 along the first wall slot 311 and the second wall slot 312 in a direction close to the CI card connector 313 until the interface on the CI card 120 is connected with the CI card connector 313 on the CI card slot 31, and similarly, when the CI card 120 is pulled out, the CI card slot 31 is also slid out in a direction away from the CI card connector 313 along the first wall slot 311 and the second wall slot 312, until the CI card 120 is completely pulled out of the adapting unit 30, so that the CI card slot 31 is connected with the CI card 120 in a plugging manner.
As an embodiment of the present application, the CI card connector 313 includes a first port for connecting a CI card 120, which is the same as CI interface 111.
As an embodiment of the present application, the CI card connector 313 is used to connect one end of the CI card 120 to mate with the CI connector 32.
It should be understood that the CI card connection port 313 is the location of the adaptor unit 30 for connecting the CI card 120, and thus the first port of the CI card connection port 313 for connecting the CI card 120 is identical to the CI interface 111, and also matches the CI connection 32.
Taking the CI interface 111 as an example with multiple rows of pins, the CI card 120 is provided with multiple rows of jacks corresponding to the multiple rows of pins, the first port of the CI card connector 313 for connecting the CI card 120 is the same as the CI interface 111, and is also provided with multiple rows of pins, and the CI connection end 32 is used for connecting the CI interface 111, so that the CI connection end 32 is also provided with multiple rows of jacks corresponding to the multiple rows of pins, that is, matched with the first port.
In practical applications, the CI interface detecting device 100 for a tv motherboard can be installed on a production line of the tv motherboard 110. When CI interface detection is required for a plurality of tv motherboards 110 in the production pipeline, the CI card 120 must be repeatedly inserted between a plurality of CI interfaces 111, that is, the CI card 120 needs to be inserted into the CI interfaces 111 a plurality of times, and the CI card 120 needs to be pulled out from the CI interfaces 111 a plurality of times. In order to avoid damage to the physical structure of the CI card 120 for connecting to the CI interface 120 due to multiple plugging operations of the CI card 120, in this embodiment, the adapting unit 30 in the CI interface detecting device 100 for the television motherboard may be used to mount the CI card 120, that is, when detecting the CI interface 111 for the television motherboard, if the CI card 120 is not damaged or needs to be replaced, the CI card 120 does not need to be taken down from the adapting unit 20, and the adapting unit 30 can be plugged and connected to the CI interface 111, so that the adapting unit 20 serves as a physical link between the CI interface 111 and the CI card 120, when the connection between the CI interface 111 and the CI card 120 is realized, loss of the CI card 120 in multiple plugging operations is replaced, further the CI card 120 is protected, and cost loss of detecting the CI interface for the television motherboard is reduced.
It should be understood that since the CI card 120 is a combination of a CAM card and an IC card, and the CI card 120 is used to convert the received encrypted Digital signal into a Television content signal, the CI interface 111 can be detected only when the Television main board 110 operates in an environment corresponding to a Digital Television (DTV) channel. In practical applications, the CI interface detection is usually performed after the DTV channel detection, that is, during the CI interface detection, the television main board 110 is already in the operating environment of the DTV channel, so how to switch to the operating environment corresponding to the DTV channel does not need to be considered. In addition, since controlling the television main board to switch signals (i.e. switch to the DTV channel) is not an improvement of this embodiment, and a scheme for implementing DTV channel switching has also been provided in the prior art, details of this part are not repeated here.
As shown in fig. 3 and 4, the present embodiment is also directed to providing a television main board 110 and a television 200. The control unit included in the television main board 110 in this embodiment is the second main control unit 20 in the previous embodiment, and the television 200 includes the television main board 110 in fig. 3.
It should be understood that, since the contents of the television main board 110 and the television 200 provided in the present embodiment and related to the present application have been described in detail in the previous embodiment, detailed description thereof is omitted.
