The interface 6024 can display a live program, the channel ID 6023 of the live program is CCTV1, and the video content and audio content of the live program are received by the device 602 from the device 601. The interface 6024 may further include a label 6025, and the content of the label 6025 may be, for example, "device 601, HDMI-1", which is used to prompt the user that the media content of the current live program is received from the HDMI-1 interface of the device 601. The label 6025 can be displayed on the interface 6024 for a short period of time (eg, 1 s or 2 s), and then disappear to avoid affecting the user's viewing of the live program. After the user exits "live TV", the device 602 can be used to surf the Internet, play games, listen to songs, etc., which is not limited in this application.

In a possible design, when the device 601 sends media content to the device 602, it can perform processing such as compression, encryption, and block transfer encoding, so that the live program displayed on the interface 6024 of the device 602 may slightly lag behind the interface 6011 of the device 601 Show the live program.

In another possible design, the device 601 may cache the media content of the live program for a specific time, the specific time is determined according to the transmission delay time between the device 601 and the device 602, and the live program is played after a specific time, so as to It is ensured that the device 601 and the device 602 can play the live program synchronously.

As shown in FIG. 7 , a schematic diagram of signal transmission between a destination device 100 and a source device 200 according to an embodiment of the present application is provided. The source device 200 is connected to the set-top box 300 , and the set-top box 300 is connected to the source device 200 through HDMI-1 (port) 2092 . The destination device 100 receives the user's operation of opening the TV player 101 (for example, the TV player 101 may be a "live TV" application), and starts the TV player. The TV player sends a first message to the TV API 102. The first message may include a device identity (ID) (eg, source device 200) and a port ID (eg, HDMI-1). The TV player 101 calls the remote adaptation module 1021 of the TV API 102. The remote adaptation module 1021 may send the first message to the connection management module 104 . The connection management module 104 can manage the connection between the destination device 100 and the source device 200 , and can perform instruction interaction with the source device 200 . The connection management module may remove the device identification from the first message and only send the port ID to the connection management module 204 of the source device 200, or the connection management module 104 may directly send the port ID (eg, HDMI-1) to the source device 200 The connection management module 204. The connection management module 204 may send the port ID to the source manager 2031 of the TV service 203 . The source manager 2031 determines that the media content needs to be read from HDMI-1 according to the port ID, and can call the HDMI player 2033 to read the media content (first media content) from HDMI-1, and send the media content through the HDMI player 2033 to SoC 207. The SoC 207 sends the media content to the transport module 206. The transmission module 206 may transmit the media content to the transmission module 106 of the destination device 100 . The transport module 106 may transmit the media content to the SoC 107 . SoC 107. The SoC 107 can decode the video content in the media content, and send the decoded video content to the display module 1011 of the TV player 101; at the same time, the SoC 107 can decode the audio content in the media content, and send the decoded video content to the display module 1011 of the TV player 101. The decoded audio content is sent to the speaker 108 , so that the destination device 100 can play the program of the set-top box 300 . In addition, the SoC 207 can also send the video content to the display module 2011 of the TV player 201, and send the audio content to the speaker 208, so that the source device 200 can play the program of the set-top box 300. In this way, multiple devices (destination device and source device) in the family can share one set-top box, that is, one set-top box can satisfy the needs of two devices (for example, two TV sets) to watch programs at the same time, which can reduce the cost of users .

It should be noted that sharing a set-top box by multiple devices refers to sharing all programs in the set-top box, including live programs (such as Spring Festival Gala live broadcast, military parade live broadcast, World Cup live broadcast, TV drama premiere, variety show live broadcast, etc.) and on-demand programs (for example, movies, reruns of TV shows, variety shows, etc.). For live programs, because digital cable TV has advantages in program sources, for example, digital cable TV has the exclusive copyrights of cctv3, cctv5, cctv6 and cctv8, users can only watch these live programs through the set-top box, which is generally placed in a fixed location ( For example, the living room), when users are watching live programs, they are easy to miss wonderful moments due to temporary things (such as going to the toilet, cooking). Therefore, users often have a desire to move to the kitchen and bedroom to continue watching. Based on the method provided by the embodiment of the present application, the user can continue to watch the live program through other devices (eg, mobile phone or tablet), which can improve the user experience.

In addition, for non-live programs, since many programs are paid programs or membership programs, it is necessary to log in and enter a password when watching. , when the user plays paid programs or membership programs through one of the devices, when the user watches these paid programs or membership programs through other devices (for example, mobile phones or tablets), there is no need to log in and enter passwords and other operations, which improves the user experience. .

In a possible design, the SoC 207 can decrypt the media content and then compress it, for example, compress the 4k media content into 1080p or 960p, and then send the compressed media content to the transmission module 106 through the transmission module 206 . The transmission module 206 can encrypt the media content based on HDCP, and then transmit the encrypted media content to the transmission module 106. The transmission module 106 decrypts the media content based on HDCP, and then uploads the decrypted media content to the SoC 107, and the SoC 107 can encrypt the media content. Perform decompression and decoding processing. In this way, it can be ensured that the media content can be safely shared.

Next, a destination device (eg, device 602) is used to establish a connection with a first source device (eg, device 601), and the first source device is connected to a first electronic device (eg, Set-top box 603), take the scenario of connecting a second electronic device (for example, set-top box 604) through a second input port (for example, HDMI-2) as an example, and describe the process of selecting a media content source and playing media content:

Device 603 can be connected to device 601 through an HDMI-1 port, and device 604 can be connected to device 601 through an HDMI-2 port. The media content of the live program displayed in the interface 6011 may be received by the device 601 from the device 604 through the HDMI-2 port. As shown in (b) of FIG. 8 , the device 602 may be a destination device (for example, a tablet computer), and the main interface 6021 of the tablet computer may include icons of multiple applications, such as a picture of the “Today” APP. , the icon of "Living Room TV", the icon of "Live TV" 6022, the icon of "Video", etc. The main interface 6021 may also include search controls, login controls, etc., which are not limited in this application. The device 602 may receive an operation of the user clicking on “Live TV” 6022, and in response to the operation, the device 602 may display an interface 6024 as shown in (c) in FIG. 8 , the interface 6024 includes a preview interface 6026 and a media content source list 6027 . The list of media content sources 6027 may include external media content sources and native media content sources. The external media content sources may include, for example, the HDMI-1 of the living room TV (ie, device 601 ) and the HDMI-2 of the living room TV, and the local media content sources may include, for example, the local AV interface. The identifiers (device identifiers and port identifiers) of external media content sources may be acquired during the process of establishing a connection between the device 602 and the device 601 . Exemplarily, as shown in (d) of FIG. 8 , in response to the user's operation of clicking on the HDMI-2 (living room TV), the device 602 may display a prompt box 6025 to prompt access to the HDMI-2 interface of the living room TV, and may The video content from the HDMI-2 interface is displayed in the preview interface 6026, and the speakers of the device 602 can play the audio content from the HDMI-2 interface. Optionally, the prompt text "connected" may be displayed after the identification of the selected media content source (for example, HDMI-2), and the prompt text "not connected" may be displayed after the identification of other unselected media content sources. .

When the destination device is connected to multiple external media content sources (for example, the source device connected to the destination device has multiple media content sources), the user can switch different external media content sources on the destination device, so as to be able to access different external media content from different external media content sources. source to watch the show. If the destination device is a touch device such as a mobile phone or tablet, the user can switch the source of the external media content through a touch operation. For example, as shown in (d) in Figure 8, when (living room TV) HDMI-2 is selected, the user can click HDMI-1 (living room TV) again to switch from (living room TV) HDMI-2 to (living room TV) HDMI-2 TV) HDMI-1.
