The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the present application, unless otherwise specified, "at least one" means one or more, "a plurality" means two or more. In addition, in order to facilitate clear description of technical solutions of the embodiments of the present application, in the embodiments of the present application, terms such as "first" and "second" are used to distinguish the same items or similar items having substantially the same functions and actions. Those skilled in the art will appreciate that the terms "first," "second," etc. do not denote any order or quantity, nor do the terms "first," "second," etc. denote any order or importance.

At present, one set top box can be used by one television, if a user wants to watch the contents in the set top box on other equipment (for example, another television), a one-to-two screen splitter is needed to realize the simultaneous playing of different televisions, which requires the wiring of an HDMI cable meeting the length requirement, and the operation is difficult. In addition, if a user wants to view the content in the set-top box on a device such as a mobile phone or a tablet, the content sharing of the set-top box cannot be realized through the screen splitter because the device does not have an HDMI port.

The embodiment of the application provides a media content sharing method, and a target device can display a first media content source and a second media content source; the first media content source and the second media content source are associated with a first source device; the target equipment responds to the operation that a user selects a first media content source and sends a first message to the first source equipment; the first source device sends first media content received from the first input port from the first electronic device to the destination device in response to receiving the first message; the target equipment receives the first media content and plays the first media content; the target equipment responds to the operation that the user selects the second media content source and sends a second message to the first source equipment; the first source device sends second media content received from the second electronic device from the second input port to the destination device in response to receiving the second message; the destination device receives the second media content and plays the second media content.

The media content source (the first media content source or the second media content source) may include at least one of an identifier of an input port, an identifier of a source device, an application corresponding to the media content, channel information of the media content, or program information of the media content. The media content source may also be referred to as a data source. The media content sources may include external media content sources (also referred to as external data sources). Or the media content sources may include external media content sources and local media content sources (which may also be referred to as local data sources).

The following description is given for the case where the destination device (e.g., device 602) establishes a connection with the first source device (e.g., device 601), and the first source device is connected to the first electronic device (e.g., set-top box 603) through the first input port (e.g., HDMI-1):

as shown in fig. 6 (a), the device 601 may be a source device (for example, may be a television), the device 601 may currently display an interface 6011 of a live program, and a channel identifier 6012 of the live program may be CCTV1. Device 603 is a set-top box connected to device 601 and the media content of the live program is sent to device 601 by device 603. As shown in fig. 6 (b), the device 602 may be a destination device (e.g., may be a tablet), and icons of a plurality of applications may be included in the main interface 6021 of the tablet, for example, icons of "today", "living room tv", "live tv" 6022 "," video ", and the like may be included. The main interface 6021 may further include a search control, a login control, and the like, which is not limited in this application. The device 602 may receive an operation by the user to click on a first application (e.g., "live television" 6022), in response to which the device 602 may display an interface 6024 as shown in (c) in fig. 6. Interface 6024 may display live programming with channel identification 6023 of CCTV1, the video content and audio content of which are received by device 602 from device 601. Interface 6024 may also include a label 6025, the content of label 6025 may be, for example, "device 601, HDMI-1" to prompt the user that media content for the currently live program is received from the HDMI-1 interface of device 601. The label 6025 may be displayed on the interface 6024 for a short time (e.g., 1s or 2 s) and then hidden to avoid affecting the user's viewing of the live program. After the user quits the live television broadcast, the user can use the device 602 to surf the internet, play games, listen to songs, and the like, which is not limited in the application.

In one possible design, the device 601 may perform compression, encryption, and block transfer encoding to transmit media content to the device 602, such that the live program displayed by the interface 6024 of the device 602 may slightly lag the live program displayed by the interface 6011 of the device 601.

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

Fig. 7 is a schematic diagram of signal transmission between a destination device 100 and a source device 200 according to an embodiment of the present application. 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 the HDMI-1 (port) 2092. The destination device 100 receives an operation of a user to open the TV player 101 (the TV player 101 may be, for example, 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 Identification (ID) (e.g., source device 200) and a port ID (e.g., HDMI-1). The TV player 101 calls the remote adaptation module 1021 of the TV API 102. Remote adaptation module 1021 may send the first message to connection management module 104. The connection management module 104 may manage the connection between the destination device 100 and the source device 200 and may be capable of performing instruction interaction with the source device 200. The connection management module may delete the device identification from the first message, send only the port ID to the connection management module 204 of the source device 200, or the connection management module 104 may send the port ID (e.g., HDMI-1) directly to the connection management module 204 of the source device 200. The connection management module 204 may transmit the port ID to the source manager 2031 of the TV service 203. The source manager 2031 determines from the port ID that the media content needs to be read from HDMI-1, may call the HDMI player 2033 to read the media content (first media content) from HDMI-1 and send the media content to the SoC 207 through the HDMI player 2033. SoC 207 sends the media content to transmission module 206. The transmission module 206 may transmit the media content to the transmission module 106 of the destination device 100. The transmission module 106 may transmit the media content to the SoC107. And a SoC107. The SoC107 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; meanwhile, the SoC107 may decode the audio content in the media content and send the decoded audio content to the speaker 108, so that the destination device 100 may play the program of the set-top box 300. In addition, the SoC 207 may also transmit video content to the display module 2011 of the TV player 201 and transmit audio content to the speaker 208, so that the source device 200 may play a program of the set-top box 300. In this way, multiple devices (destination device and source device) in a home can share one set top box, that is, the requirement of two devices (for example, two televisions) for watching programs can be met simultaneously through one set top box, and the cost of a user can be reduced.

It should be noted that, sharing one set top box by multiple devices means sharing all programs in the set top box, including live programs (such as live broadcast in spring and evening, live broadcast in soldier, live broadcast in world cup, live broadcast in drama, live broadcast in anarchia, etc.) and on-demand programs (such as movies, replayed dramas, anarchia, etc.). For the live programs, since the cable digital television has advantages in terms of program sources and the like, for example, the cable digital television has exclusive copyright of cctv3, cctv5, cctv6 and cctv8, and the cable digital television can only watch the live programs through the set-top box, the set-top box is generally placed at a fixed position (for example, a living room), and when the user watches the live programs, the user easily misses wonderful moments due to temporary events (such as going to the toilet and cooking). Users often have appeal to move to the kitchen and bedroom for continued viewing. Based on the method provided by the embodiment of the application, the user can continuously watch the live program through other equipment (such as a mobile phone or a tablet), so that the user experience can be improved.

In addition, for non-live programs, since many programs are pay programs or member programs, and login and password input are required during watching, according to the method provided by the embodiment of the application, after a user orders the pay programs or the member programs comprising a plurality of devices, when the user plays the pay programs or the member programs through one device, the user does not need to perform operations such as login and password input when watching the pay programs or the member programs through other devices (for example, a mobile phone or a tablet), and the user experience is improved.

In one possible design, soC 207 may decrypt and compress the media content, for example, 4k of the media content may be compressed to 1080p or 960p, and then the compressed media content may be sent to transmission module 106 through 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 upload the decrypted media content to the SoC107, and the SoC107 can decompress and decode the media content. In this way, secure sharing of media content can be ensured.

The following description is given for the example of a scenario in which a destination device (e.g., device 602) establishes a connection with a first source device (e.g., device 601), and the first source device is connected to a first electronic device (e.g., set top box 603) through a first input port (e.g., HDMI-1) and a second electronic device (e.g., set top box 604) through a second input port (e.g., HDMI-2), respectively, to select a media content source and play media content:

As shown in fig. 8 (b), the device 602 may be a destination device (e.g., may be a tablet), and icons of a plurality of applications may be included in the main interface 6021 of the tablet, for example, may include a picture of "today" APP, an icon of "living room tv", an icon of "live tv" 6022, an icon of "video", and the like. The main interface 6021 may further include a search control, a login control, and the like, which is not limited in this application. The device 602 may receive an operation by the user to click on "live tv" 6022, in response to which the device 602 may display an interface 6024 as shown in (c) in fig. 8, the interface 6024 including a preview interface 6026 and a media content source list 6027. The media content sources list 6027 may include external media content sources and native media content sources. External media content sources may include, for example, HDMI-1 for a living room television (i.e., device 601) and HDMI-2 for a living room television, and local media content sources may include, for example, a local AV interface. The identification of the external media content source (device identification and port identification) may be obtained during the process of establishing a connection between the device 602 and the device 601. Illustratively, as shown in fig. 8 (d), in response to a user clicking on 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 display video content from the HDMI-2 interface at the preview interface 6026, and the speakers of the device 602 may play audio content from the HDMI-2 interface. Optionally, the prompt text "accessed" may be displayed after the identification of the selected media content source (e.g., HDMI-2) and the prompt text "not accessed" may be displayed after the identification of the other unselected media content sources.

When the destination device is connected to multiple external media content sources (e.g., the source device to which the destination device is connected has multiple media content sources), the user can switch different external media content sources on the destination device, thereby enabling viewing of programs from different external media content sources. If the destination device is a touch device such as a mobile phone or a tablet computer, the user can switch the external media content source through touch operation. For example, as shown in fig. 8 (d), when (living room tv) HDMI-2 is in the selected state, the user clicks HDMI-1 (living room tv) again, and can switch from (living room tv) HDMI-2 to (living room tv) HDMI-1. If the destination device is a television, the user may switch the source of the external media content through voice or a remote control device (e.g., a remote control). Of course, the user may switch from the external media content source to the local media content source (e.g., from HDMI-2 (parlor tv) to the AV interface), or from the local media content source to the external media content source (e.g., from the AV interface to HDMI-2 (parlor tv)), which is not limited in this application.

Optionally, after the user exits the "live tv broadcast" application, the "live tv broadcast" application may store the media content source information (e.g., HDMI-2 (living room television)) selected last time by the user, and when the user opens the live tv broadcast application next time, the media content source information selected last time by the user is selected by default.

Fig. 9 is a schematic diagram of signal transmission between a destination device 100 and a source device 200 according to an embodiment of the present application. A P2P connection may be established between the destination device 100 and the source device 200, or the destination device 100 and the source device 200 may be connected to the same local area network. The source device 200 is connected to two set-top boxes, i.e., a set-top box 300 and a set-top box 400. The set-top box 300 is connected to the source device 200 through the HDMI-1 (port) 2092, and the set-top box 400 is connected to the source device 200 through the HDMI-2 (port) 2094. The destination device 100 may receive an operation of a user to open the TV player 101 (the TV player 101 may be, for example, a "live TV" application), and start the TV player. In response to an operation of the user selecting HDMI-2 (living room TV, i.e., source device 200) from the media content source list of the TV player 101, the TV player 101 may transmit a second message to the TV API 102. The second message may include a device identification (i.e., source device 200) and a port identification (i.e., HDMI-2). The TV player 101 may send the second message to the connection management module 104 through the remote adaptation module 1021 of the TV API 102. The connection management module 104 may manage the connection between the destination device 100 and the source device 200 and may be capable of performing instruction interaction with the source device 200. The connection management module may delete the device identification from the second message, send only the port ID to the connection management module 204 of the source device 200, or the connection management module 104 may send the port ID (e.g., HDMI-2) directly to the connection management module 204 of the source device 200. After receiving the port ID, the connection management module 204 calls the source manager 2031 of the TV service 203. The source manager 2031 calls the HDMI player 2033 to read the media content from the HDMI-2 and sends the media content to the SoC 207 through the HDMI player 2033. SoC 207 sends the media content to transmission module 206. The transmission module 206 may transmit the media content to the transmission module 106 of the destination device 100. The transmission module 106 may transmit the media content to the SoC107. The SoC107 can decode the video content and send the decoded video content to the display module 1011 of the TV player 101; meanwhile, soC107 may perform decoding processing on the audio content and send the decoded audio content to speaker 108, so that destination device 100 may play the program of set-top box 400. Of course, after the source manager 2031 of the source device 200 reads the media content from the HDMI-2, the media content may be transmitted to the SoC 207 at the same time, the SoC 207 may transmit the video content to the display module 2011 of the TV player 201 and transmit the audio content to the speaker 208, so that the source device 200 may play the program of the set-top box 400. Therefore, a plurality of household devices (destination devices and source devices) can share one set top box, that is, the requirement of two devices (for example, two television sets) for watching programs can be met simultaneously through one set top box, and the cost of a user can be reduced.

The following describes a process of selecting a media content source and playing media content, taking as an example a scenario where a destination device (e.g., device 602) establishes a connection with two source devices (including a first source device, which may be, for example, device 601, and a second source device, which may be, for example, device 605), the first source device is connected to a first electronic device (e.g., set top box 603) through a first input port (e.g., HDMI-1), the second electronic device (e.g., set top box 604) is connected to a second input port (e.g., HDMI-2), and the second source device is connected to a third electronic device (e.g., set top box 606) through a third input port (e.g., HDMI-3):

as shown in fig. 10 (a), the device 601 may be, for example, a television, and the device 601 may currently display an interface 6011 of a live program, where a channel identifier 6012 of the live program may be CCTV8. Device 603 and device 604 may be set-top boxes connected to device 601, and media content for live programming may be received by device 601 from device 603 or device 604. As shown in fig. 10 (b), the device 605 may be a source device (e.g., may be a television), the device 605 may currently display an interface 6051 for live programming whose channel identification 6052 may be a hunan satellite view. Device 603 and device 604 may be set-top boxes connected to device 605, and media content for live programming may be received by device 605 from device 606. As shown in (c) of fig. 10, the device 602 may be a destination device (e.g., may be a tablet), and the device 602 may display an interface 6024 as shown in (c) of fig. 10, including a preview interface 6026 and a media content source list 6027 in the interface 6024. The media content sources list 6027 may include, among other things, external media content sources and local media content sources. External media content sources may include, for example, HDMI-1 for a living room television (i.e., device 601), HDMI-2 for a living room television, and HDMI-3 for a bedroom television (i.e., device 605), and local media content sources may include, for example, an AV interface. The external media content sources may be obtained during the process of device 602 establishing connections with other devices (i.e., device 601 and device 605). Illustratively, in response to a user clicking on the identification of HDMI-3 (bedroom television), a prompt box 6028 may be displayed to prompt the device 601 to read the HDMI-3 interface of the bedroom television, and video content from the HDMI-3 interface may be displayed at the preview interface 6026, and speakers of the device 602 may play audio content from the HDMI-3 interface.

Alternatively, if all media content sources of other devices (e.g., device 601) connected to device 602 are displayed in media content source list 6027, the prompt text "accessed" may be displayed after the identification of the media content source (e.g., HDMI-3 (bedroom television)) connected to the set top box, the prompt text "not accessed" may be displayed after the identification of the media content source not connected to the set top box, the availability of the media content sources of other devices may be made clear to the user, and the user may select a media content source from the "accessed" media content sources, so that the program of the media content source may be viewed.

Fig. 11 is a schematic diagram of signal transmission between a destination device 100 and a source device 200 (a first source device) and between the destination device 100 and a source device 500 (a second source device) according to an embodiment of the present application. The destination device 100 and the source device 200 and the source device 500 may establish a P2P connection, or the destination device 100 and the source device 200 and the source device 500 may be connected to the same local area network. The source device 200 is connected to two set-top boxes, namely, a set-top box 300 and a set-top box 400. The set-top box 300 is connected to the source device 200 through the HDMI-1 (port) 2092, and the set-top box 400 is connected to the source device 200 through the HDMI-2 (port) 2094. The source device 500 is connected to the set-top box 600, and the set-top box 600 is connected to the source device 500 via the HDMI-3 (port) 5092. In response to an operation of the user selecting the HDMI-3 port of the source device 500 from the media content source list of the TV player 101 of the destination device 100, the TV player 101 sends a fourth message to the TV API 102. The fourth message may include a device identification (i.e., source device 500) and a port identification (i.e., HDMI-3). The TV API 102 sends a fourth message to the connection management module 104 via the remote adaptation module 1021. The connection management module 104 may manage connection of the destination device 100 with different source devices (the source device 200 and the source device 500) and may be capable of performing instruction interaction with the different source devices. The connection management module may delete the device identification from the fourth message, send only the port ID (e.g., HDMI-3) to the connection management module 204 of the source device 200, or the connection management module 104 may send the port ID (e.g., HDMI-3) directly to the connection management module 204 of the source device 200. After receiving the port ID, the connection management module 504 calls the source manager 5031 of the TV service 503. The source manager 5031 acquires the media content from the HDMI-3 port 5094 through the HDMI player 5033, and sends the media content to the SoC 507 through the HDMI player 5033. The SoC 507 sends the media content to the transmission module 506. The transmission module 506 transmits the media content to the transmission module 106, and the transmission module 106 may send the received media content to the SoC107. The SoC107 may decode the video content and send the decoded video content to the display module 1011 of the TV player 101; meanwhile, the SoC107 may perform decoding processing on the audio content and send the decoded audio content to the speaker 108, so that the destination device 100 may play the program of the set-top box 600. Of course, after the source manager 5031 of the source device 500 obtains the media content, the media content may be transmitted to the SoC 507 at the same time, the SoC 507 may transmit the video content to the display module 5011 of the TV player 501 and the audio content to the speaker 508, so that the source device 500 may play the program of the set-top box 600. In this way, the destination device 100 and the source device 500 may share the set-top box 600, that is, the requirement of two devices to watch television may be met simultaneously through one set-top box, which may reduce the cost of the user.

It is understood that the connection management module 104 of the destination device 100 may maintain a connection with the connection management module 204 of the source device 200, and if a user needs to switch the media content source, for example, from the HDMI-3 interface of the source device 500 to the HDMI-1 interface of the source device 200, the connection management module 104 may send a corresponding message to the connection management module 504 of the source device 500 to obtain the corresponding media content based on the connection of the destination device 100 and the source device 200.

The following describes a process of selecting a channel (switching a channel) in a scenario where a destination device (e.g., device 602) establishes a connection with a first source device (e.g., device 601), and the first source device is connected to a first electronic device (e.g., set top box 603) through a first input port (e.g., HDMI-1):

as shown in (a) of fig. 12, a device 601 may be a source device (for example, may be a television), and an interface 6011 currently displayed by the device 601 may display a live program, and a channel identifier 6012 of the live program may be a station caption of a south of the lake satellite television. Device 603 is a set-top box connected to device 601 and media content of a live program of a south of the Hunan satellite is transmitted to device 601 by device 603. As shown in (b) in fig. 12, the device 602 may view a live program of the south of the lake satellite television through the device 601, when a user needs to change channels, the program 6100 may be called through voice or touch operation, where the program 6100 includes a plurality of entries, each entry corresponds to a name and a channel of a television station (satellite television), and for example, the entry 6101 indicates that the channel of the south of the lake satellite television is 023. When the user switches channels (zaps) on the destination device 602, the device 602 may send a zapping (zapping) instruction to the device 601, and the device 601 performs corresponding processing according to the zapping instruction, and may send the zapped media content to the device 602. For example, if the user clicks on the entry 6102 on the program list 6100 while the entry 6101 is in the selected state, as shown in (c) in fig. 12, the device 602 may switch from the interface 6021 to the interface 6029, i.e., from the south of the lake satellite view to the river satellite view. Meanwhile, as shown in (d) in fig. 12, the apparatus 601 may switch from the interface 6011 to the interface 6013, i.e., from the south of lake satellite view to the river satellite view. In the interface 6013, a live program of the zhejiang satellite television may be displayed, and the channel identifier 6014 of the live program may be a station logo of the zhejiang satellite television. In this way, the user can switch channels (zap) on the destination device without the user interacting with the source device to zap (e.g., going to the room where the source device is located to zap), which can improve the user experience.

Fig. 13 is a schematic diagram of signal transmission between a destination device 100 and a source device 200 according to an embodiment of the present application. A P2P connection is established between the destination device 100 and the source device 200, or the destination device 100 and the source device 200 may be connected to the same local area network. 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 an HDMI-1 (port) 2092. The transmission module 106 of the destination device 100 may receive the media content of the HDMI-1 (port) 2092 from the transmission module 206 of the source device 200 and transmit the received media content to the SoC107. The SoC107 can decode the video content and send the decoded video content to the display module 1011 of the TV player 101; meanwhile, the SoC107 may decode the audio content and send the decoded audio content to the speaker 108, so that the destination device 100 may play the program of the set-top box 300. In response to a user operation to switch channels (e.g., from channel 023 to channel 024), the TV player may send a fifth message to the TV API 102, which may include information of the channel to be switched (the information of the channel to be switched may be an identification of the previous, next or channel (e.g., channel 024), etc.). The TV player 101 calls the remote adaptation module 1021 of the TV API 102. The remote adaptation module 1021 may send the fifth message to the connection management module 104. The connection management module 104 may manage the connection between the destination device 100 and the source device 200 and may be capable of performing instruction interaction with the source device 200. The connection management module transmits information of the channel to be switched to the connection management module 204 of the source device 200. The connection management module 204 may determine a port DI corresponding to a channel to be switched, and may send the port ID and information of the channel to be switched to the switching service API 205. The switching service API 205 may send a sixth message to the switching device 700 through a bluetooth connection, where the sixth message may include a port ID and information of a channel to be switched, the switching device 700 sends a seventh message to the set top box 300, and the switching device may send the seventh message to the set top box 300 through an infrared or bluetooth connection. The seventh message may include information of a channel to be switched, and the set-top box 300 may switch the channel in response to receiving the seventh message. Then, the source manager 2031 acquires the media content from the HDMI-1 (port) 2094 through the HDMI player 2033, and transmits the media content to the SoC 207 through the HDMI player 2033. SoC 207 sends the media content to transmission module 206. The transmission module 206 transmits the media content to the transmission module 106, and the transmission module 106 may send the received media content to the SoC107. The SoC107 can decode the video content and send the decoded video content to the display module 1011 of the TV player 101; meanwhile, the SoC107 may decode the audio content and send the decoded audio content to the speaker 108, so that the destination device 100 may play the program switched by the set-top box 300. In addition, after the source manager 2031 of the source device 200 transmits the switched media content to the SoC 207, the SoC 207 may transmit the video content to the display module 2011 of the TV player 201 and transmit the audio content to the speaker 208, so that the source device 200 may play the program switched by the set-top box 300.

As shown in fig. 14 (a), the device 601 may be a source device (e.g., may be a television), and the device 601 is in a screen-off state. As shown in fig. 14A, when the source device 200 is turned off, the connection management module 204 may be guaranteed to be in an operating state by "heartbeat", and other modules except the connection management module 204 may be in a sleep state (e.g., the source manager 2031, the display module 2011 and the speaker 208, and the AP in the SoC 207, etc.). Wherein, the "heartbeat", i.e. the interaction of the heartbeat message by the connection management module 204 and the connection management module 104 is performed according to a preset period (e.g. 30 s). When the connection management module 204 receives a specific message (e.g., a first message) sent by the connection management module 104, the source manager 2031 entering the sleep may be woken up. Device 603 is a set-top box connected to device 601. As shown in fig. 14 (b), the device 602 can view a live program of the south of the lake satellite through the device 601. When the user switches a channel (zaps) on the destination device 602, the device 602 may send a zapping instruction to the device 601, the device 601 may forward the zapping instruction to the switching device via the bluetooth connection, and the switching device switches the channel of the set-top box 603 via infrared signals. In this way, device 601 may receive the zapped media content from device 603, and device 601 may send the zapped media content to device 602. For example, when the user needs to change channels, the program list 6100 may be called through voice or touch operation, and the program list 6100 includes a plurality of entries. When the entry 6101 is in the selected state, if the user clicks on the entry 6102 on the program guide 6100, as shown in (c) of fig. 14, the device 602 may switch from the interface 6021 to the interface 6029, i.e., from the south of the lake satellite view to the river satellite view.

In one possible design, as shown in fig. 13, after the source manager 2031 of the source device 200 sends the switched media content to the SoC 207, the SoC 207 does not send the video content to the display module 2011 of the TV player 201 and does not send the audio content to the speaker 208), that is, the source device 200 does not play the program of the set-top box 300, and is in the off-screen state.

In another possible design, as shown in fig. 14A, the TV service 203 of the source device 200 may receive unencrypted media content from the set top box 300 (digital television set top box) 2092 from HDMI player 2033, and the HDMI player 2033 may send the unencrypted media content to the transmission module 206 for the transmission module 206 to send the media content to (the transmission module 106 of) the destination device 100.

The following describes a process of selecting a channel (switching channels) in a scenario in which a destination device (e.g., device 602) establishes a connection with a first source device (e.g., device 601), and the first source device is connected to a first electronic device (e.g., set top box 603) through a first input port (e.g., HDMI-1) and a second electronic device (e.g., set top box 604) through a second input port (e.g., HDMI-2), respectively:

as shown in fig. 15 (a), a device 601 may be a source device (e.g., may be a television), and a device 603 and a device 604 are set-top boxes connected to the device 601. Device 603 may connect to device 601 through an HDMI-1 port and device 604 may connect to device 601 through an HDMI-2 port. The device 601 may currently display the interface 6011, and the program content of the interface 6011 may be obtained by the device 601 from the device 604 through the HDMI-2 port, or the program content of the interface 6011 may be obtained from a network (huaye video server). As shown in fig. 15 (b), device 602 can view live programming through the HDMI-1 port of device 601, the media content of which is from device 603. When the user switches channels (zaps) on the destination device 602, the device 602 may send a zapping (zapping) instruction to the device 601, and the device 601 performs corresponding processing according to the zapping instruction, and may send the zapped media content to the device 602. Illustratively, when a user needs to change channels, the program 6100 may be called through voice or touch operation, where the program 6100 includes a plurality of entries, each entry corresponds to a name and a channel of a satellite television, for example, the entry 6101 indicates that the channel of the satellite television in the south of the lake is 023. When the entry 6101 is in the selected state, if the user clicks on the entry 6102 on the program list 6100, as shown in (c) in fig. 15, the device 602 may switch from the interface 6021 to the interface 6029, that is, from the hunan satellite view to the zhejiang satellite view. Meanwhile, as shown in (d) of fig. 15, the program currently played by the device 601 is not changed, i.e., the program content from the device 604 is still displayed in the interface 6011.

Fig. 16 is a schematic diagram illustrating signal transmission between a destination device 100 and a source device 200 according to an embodiment of the present application. A P2P connection may be established between the destination device 100 and the source device 200, or the destination device 100 and the source device 200 may be connected to the same local area network. The source device 200 is connected to two set-top boxes, namely, a set-top box 300 and a set-top box 400. The set-top box 300 is connected to the source device 200 through the HDMI-1 (port) 2092, and the set-top box 400 is connected to the source device 200 through the HDMI-2 (port) 2094. The transmission module 106 of the destination device 100 may receive the media content of the HDMI-2 (port) 2094 from the transmission module 206 of the source device 200 and transmit the received media content to the SoC107. The SoC107 can decode the video content and send the decoded video content to the display module 1011 of the TV player 101; meanwhile, soC107 may perform decoding processing on the audio content and send the decoded audio content to speaker 108, so that destination device 100 may play the program of set-top box 400. In response to a user's operation to switch channels (e.g., from channel 023 to channel 024), the TV player 101 may send a fifth message to the TV API 102, which may include information of the first channel (which may be a last channel, a next channel, or an identification of a channel (e.g., channel 024), etc.). The TV player 101 calls the remote adaptation module 1021 of the TV API 102. The remote adaptation module 1021 may send the fifth message to the connection management module 104. The connection management module 104 may manage the connection between the destination device 100 and the source device 200 and may be capable of performing instruction interaction with the source device 200. The connection management module may transmit the information of the first channel to the connection management module 204 of the source device 200. The connection management module 204 may determine a port ID (e.g., HDMI-2) corresponding to the first channel, and may transmit the port ID and information of the first channel to the switching service API 205. The switching service API 205 may transmit the information of the port ID and the first channel to the switching device 700 through a bluetooth connection, and the switching device 700 transmits an infrared signal to the set-top box 400 to control the set-top box 400 to switch the channel. The switching device 700 is an infrared control device paired with the set top box 400, and the source device 200 may establish a bluetooth connection with the switching device 700 and perform signaling interaction with the switching device 700 based on the bluetooth connection, so that the switching device 700 controls the set top box 400 to switch channels. Then, the source manager 2031 acquires the media content of the set top box 400 from the HDMI-1 (port) 2094 through the HDMI player 2033, and transmits the media content to the SoC 207 through the HDMI player 2033. SoC 207 sends the media content to transmission module 206. The transmission module 206 transmits the media content to the transmission module 106, and the transmission module 106 may send the received media content to the SoC107. The SoC107 may decode the video content and send the decoded video content to the display module 1011 of the TV player 101; meanwhile, the SoC107 may decode the audio content and send the decoded audio content to the speaker 108, so that the destination device 100 may play the program switched by the set-top box 400.

Meanwhile, the source manager 2031 of the source device 200 may acquire the media content of the set-top box 300 from the HDMI-1 (port) 2092 through the HDMI player 2034 and transmit the media content to the SoC 207, and the SoC 207 may transmit the video content to the display module 2011 of the TV player 201 and the audio content to the speaker 208, so that the source device 200 may play the program of the set-top box 300.
