Abstract: Disclosed are a display apparatus and a split-screen playback method. The method includes: upon receiving media data pushed from the terminal device, detecting a type of a current signal source of the display apparatus; in response to the type of the current signal source being included in a source list, starting a split-screen playback mode in the display apparatus, generating a first window and a second window, presenting the first window and the second window, on a display, and displaying video data from the current signal source in the first window and displaying the media data from the terminal device in the second window; in response to the type of the current signal source being not included in the source list, not generating the first window and the second window, and presenting the video data from the current signal source in a full-screen mode on the display.

Abstract: The present application is directed to a multimedia apparatus and a cast method. The method includes: during a cast process between a display apparatus and multiple devices, determining a target device from among the multiple devices; storing audio data which is sent from the target device in an audio buffer, and discarding audio data sent from other devices; storing video data which is sent from the multiple devices in video buffers corresponding to the devices; and playing the audio data in the audio buffer, and displaying video data in at least one video buffer.
