Step 603, first vision signal and the second vision signal are transmitted to media output interface by transmitting device.
In integrated terminal, transmitting device is connected with collection coding chip, therefore in collection coding chip to collection
Or receive after video flowing encoded, the vision signal after its coding exported can be exported by transmitting device to media
Port exports, also i.e., it is possible to transmit the first vision signal and the second vision signal to media output port by transmitting device.
For example, after issue is live, integrated terminal is gathered by cradle head camera or receives video flowing all the way, at the same time
It can be adopted by such as high-definition multimedia interface (High Definition Multimedia Interface, HDMI) numeral
Video flowing, this two-path video stream, can be defeated with transmitting device after decoding all the way for the collection of the media input interfaces such as Ji Kou or reception
Go out to decoding chip, to be decoded by decoding chip, and pass through such as HDMI output interface (HDMI OUT) after the decoding
Deng media output interface output at least video flowing all the way, so that the display for connecting the HDMI OUT, which closes screen, shows high-definition image.
Optionally, the integrated terminal in the embodiment of the present application can also include decoding chip, to use decoding chip pair
The vision signal that transmitting device 53 is transmitted is decoded, and decoded video flowing is exported to media delivery outlet 54, and
At least video flowing all the way is exported by the media delivery outlet 54, so that the display device for connecting the media output interface can be with
Video flowing composograph according to the media delivery outlet 54 output.Wherein, decoding chip one end connection transmission device 53, to receive
The vision signal that transmitting device 53 is transmitted, other end connection media output interface 54, decoded video is streaming to
The media output interface 54.The decoding chip specifically can be used for solving the vision signal of the transmitting device 53 transmission
Code, and at least video flowing all the way is exported by the media output interface 54 after the decoding.
