For example, multimedia content from the network, such as video resources from online movies and TV, or short videos in applications, can be obtained through HTTP protocol. The central display screen 22 is connected to the central control host 21 , and can play the multimedia content acquired by the central control host 21 . The A-pillar display module 23 can also be used to receive and play the multimedia content acquired by the central control host 21 .

Further, the central control host 21 is configured to play multimedia content through the central display screen 22 (usually a horizontal screen) when it is determined that the playback mode is horizontal screen playback, and when it is determined that the playback mode is vertical screen playback, send multimedia content. The content is played on the A-pillar display module 23 (with a vertical screen).

Specifically, the multimedia content acquired by the central control host 21 may have a display label, the display label includes a vertical screen display label and a horizontal screen display label, and the central control host 21 is configured to determine through the display label that the playback mode of the multimedia content is landscape. Play or play in portrait orientation. For example, when the multimedia content has a horizontal screen display label, the central control host 21 determines that the playback mode is horizontal screen playback, and when the multimedia content has a vertical screen display label, the central control host 21 determines that the playback mode is vertical screen playback.

More specifically, the A-pillar display module 23 may further include a touch screen 230 , and the A-pillar display module 23 is configured to display a play button, a pause button and a fast forward/backward button on the touch screen 230 .
