Detailed Description
To make the objects, technical solutions and advantages of the exemplary embodiments of the present application clearer, the technical solutions in the exemplary embodiments of the present application will be clearly and completely described below with reference to the drawings in the exemplary embodiments of the present application, and it is obvious that the described exemplary embodiments are only a part of the embodiments of the present application, but not all the embodiments.
The present application relates to a display terminal including at least two system-on-chip, and for ease of understanding, a display terminal of a multi-chip structure is described herein.
For the convenience of users, various external device interfaces are usually provided on the display device to facilitate connection of different peripheral devices or cables to implement corresponding functions. When a high-definition camera is connected to an interface of the display device, if a hardware system of the display device does not have a hardware interface of a high-pixel camera receiving the source code, data received by the camera cannot be displayed on a display screen of the display device.
Furthermore, due to the hardware structure, the hardware system of the conventional display device only supports one path of hard decoding resources, and usually only supports video decoding with a resolution of 4K at most, so when a user wants to perform video chat while watching a network television, the user needs to use the hard decoding resources (usually GPU in the hardware system) to decode the network video without reducing the definition of the network video screen, and in this case, the user can only process the video chat screen by using a general-purpose processor (e.g. CPU) in the hardware system to perform soft decoding on the video.
The soft decoding is adopted to process the video chat picture, so that the data processing burden of a CPU (central processing unit) can be greatly increased, and when the data processing burden of the CPU is too heavy, the problem of picture blocking or unsmooth flow can occur. Further, due to the data processing capability of the CPU, when the CPU performs soft decoding on the video chat screen, multi-channel video calls cannot be generally implemented, and when a user wants to perform video chat with multiple other users in the same chat scene, access is blocked.
In view of the above aspects, to overcome the above drawbacks, the present application discloses a dual hardware system architecture to implement multiple channels of video chat data (at least one channel of local video).
The concept to which the present application relates will be first explained below with reference to the drawings. It should be noted that the following descriptions of the concepts are only for the purpose of facilitating understanding of the contents of the present application, and do not represent limitations on the scope of the present application.

The first controller 101 comprises a first control schedule 101-2, the first control schedule 101-2 is configured to register a broadcast listener, and the broadcast listener executes corresponding processing on Intent of a broadcast according to a broadcast type after monitoring the broadcast, and sends out the processed broadcast.
And the second controller 201 comprises a second control schedule 201-1, and the second control schedule 201-1 is configured to receive the broadcast output from the first control schedule 101-2, process the broadcast and send the processed broadcast to the corresponding application 201-2 of the second controller 201.
Here, for convenience of description, the processor 310 in fig. 4 and 5 corresponds to the first controller 101 in fig. 9, and the processor 210 in fig. 4 and 5 corresponds to the second controller 201 in fig. 9, which will not be described below.
The Android system provides an Intent mechanism to assist interaction and communication among applications, the Intent is responsible for describing actions, action related data and additional data of one-time operation in the applications, and the Android system is responsible for finding a corresponding component, transmitting the Intent to a called component and finishing scheduling of the component according to the description of the Intent. The other purpose of Intent is to send broadcast messages, both the application program and the Android system can use Intent to send broadcast messages, and the content of the broadcast messages can be data information closely related to the application program, namely ordinary broadcast; or Android system information, that is, system broadcast, such as application installation uninstallation broadcast, usb disk plug broadcast, monitoring network change broadcast, and the like.
In order to identify whether the broadcast transmitted by the first controller 101 is a system broadcast or a general broadcast, a system broadcast listener for listening whether the first controller 101 transmits the system broadcast or not and a general broadcast listener for listening whether the application 101-1 of the first controller 101 transmits the general broadcast or not are registered in the first control schedule 101-2. As shown in fig. 10, if the system broadcast listener hears the system broadcast transmitted by the first controller 101, the first controller 101 transmits the system broadcast to the first control schedule 101-2. After receiving the system broadcast from the first controller 101, the first control schedule 101-2 needs to modify an Action (attribute Action) corresponding to the Intent of the system broadcast, and adds a broadcast identifier to the Action.
Because the first controller 101 and the second controller 201 belong to two independent systems respectively, each system sends out a system broadcast, and the Action names corresponding to the Intent of the system broadcast are the same, after the system broadcast sent out by the first controller 101 is forwarded to the second controller 201 without modification, the application of the second controller 201 cannot distinguish whether the system broadcast is the system broadcast sent out by the second controller 201 itself or the broadcast transmitted by the first controller 101, and cannot perform corresponding logic processing, so that an identifier needs to be added to the system broadcast, and the system broadcast is sent out by the chip or transmitted by another chip is identified by the identifier.
After the first control schedule 101-2 receives the system broadcast from the first controller 101, the broadcast identification added in the Action is the identification that the system broadcast from the first controller 101, i.e., the addition of. That is, the content of the Intent of the system broadcast transmitted by the first controller 101 is: intent Action: origin, the content of the first control schedule 101-2 after adding the identifier to Intent is: intent Action: from a.
After adding a broadcast identifier to the Intent of the system broadcast sent by the first controller 101, a new Intent is sent to the second controller 201. When the Intent is used to transfer the object, there are two general implementation ways, one is Serializable, that is, an object is converted into a storable or transmittable state, and the serialized object can be transmitted over a network or stored locally; the other is Parcellable, and the realization principle of the Parcellable mode is to decompose a complete object, and each part after decomposition is a data type supported by Intent, so that the function of transferring the object can be realized.
When the first control schedule 101-2 sends Intent to the second controller 201, a serialization mode is adopted, namely the Intent added with the broadcast identifier is serialized and converted into a String character String, and the converted String character String is sent to the second control schedule 201-1.
After receiving the String transmitted from the first control schedule 101-2, the second control schedule 201-1 needs to deserialize Intent, that is, convert the String into an Intent object, to obtain the system broadcast content transmitted by the first controller 101. After the second control schedule 201-1 obtains the converted Intent object, a sendBroadcast interface of the second controller is called, and the Intent object is sent to the application 201-2 registered in the system broadcast in the second controller 201 through the sendBroadcast interface.
The application takes the example that the usb disk is inserted into the first controller 101, and the second controller 201 needs to receive the usb disk plug broadcast of the first controller 101. The first control dispatch 101-2 registers the USB plug system broadcast (action: android. action. MEDIA _ MOUNTED/action: android. action. MEDIA _ UNMOUNTED), when the first controller 101 sends out the USB plug broadcast, the system broadcast monitor in the first control dispatch 101-2 monitors that the first controller 101 sends out the USB plug broadcast, the first control dispatch 101-2 receives the USB plug broadcast sent by the first controller 101, then the first control dispatch 101-2 modifies the action (action: android. action. MEDIA _ MOUNTED. A) corresponding to the instruction, then the first control dispatch 101-2 sequences the modified instruction, converts the modified instruction into the String (file://// C25/78-D496; the instruction 101-2 sequences the modified instruction, converts the modified instruction into the second String [ String ] String _// C25/25F-D # 0030.0010.1.1., converting the String character String into an Intent object, calling a sendBroadcast interface of the second controller 201, and sending the converted Intent to the application registered with the broadcast in the second controller 201, so as to display the usb disk plugging broadcast in the application related to the second controller 201.
As shown in fig. 11, if the general broadcast listener hears the normal broadcast transmitted by the application 101-1 of the first controller 101, the application 101-1 of the first controller 101 transmits the normal broadcast into the first control schedule 101-2. The application 101-1 of the first controller 101 sends the Intent content of the normal broadcast as: intent Action: xxx. COMMON Extra: intetb, where the parameter Extra is Intent sent to the second controller 201.
After receiving the normal broadcast sent by the application 101-1 from the first controller 101, the first control schedule 101-2 obtains intetb to be sent to the second controller 201 from the Intent, that is, the value in the parameter Extra parameter in the Intent, serializes the intetb into a String, and then sends the String to the second control schedule 201-1.
After receiving the String transmitted from the first control schedule 101-2, the second control schedule 201-1 needs to deserialize the Intent, i.e., convert the String into an Intent object, to obtain the ordinary broadcast content transmitted by the application 101-1 of the first controller 101. After the second control scheduler 201-1 obtains the converted Intent object, it schedules the sendBroadcast interface of the second controller 201, and sends the Intent object to the application 201-2 registered with the broadcast in the second controller 201 through the sendBroadcast interface.
The application is described by taking an example in which the application of the first controller 101 transmits a general broadcast, and the second controller 201 receives the general broadcast transmitted by the first controller 101. The first control schedule 101-2 registers a COMMON BROADCAST (Action: com. hisense x x.x.x.common _ BROADCAST), when an application of the first controller 101 needs to transmit the BROADCAST to the second controller 201, the application of the first controller 101 sends out a BROADCAST of this Action, carrying a COMMON _ xxx parameter, which is an Intent actually forwarded to the second controller, to the first control schedule 101-2, the first control schedule 101-2 obtains the value in the COMMON _ xxx parameter, and then the first control schedule 101-2 serializes the obtained value, converts it into a String (e.g. "# Intent; ion \ u 003djs. high. senx. xxx; launchtags 003d0x 0010; s.003wu. and sends it to the second control schedule 201. after receiving the String, and sending it to the second control schedule 201. map 1. xxv.m. and sending it to the second control schedule 201. map 1. and sending it to the second control schedule 201. c.m. 2, deserializing Intent, i.e., converting the String into an Intent object, then calling the sendBroadcast interface of the second controller 201, and sending the converted Intent to the application registered in the second controller 201 to display the normal broadcast in the application associated with the second controller 201.
In this example, the first controller 101 may be an a chip, and the second controller 201 is a corresponding N chip, that is, the a chip sends a system broadcast to an application registered in the N chip for the broadcast, or a certain application in the a chip sends a general broadcast to an application registered in the N chip for the broadcast, so that the broadcast of the a chip is spread to the N chip across systems, and synchronization and interaction of data are realized. Similarly, the first controller 101 may also be an N chip, and the second controller 201 is a corresponding a chip, that is, the N chip sends a system broadcast to an application registered in the a chip for the broadcast, or a certain application in the N chip sends a common broadcast to an application registered in the a chip for the broadcast, so that the broadcast of the N chip is spread to the a chip across systems, and synchronization and interaction of data are realized.
When the first controller 101 sends a system broadcast to the second controller 201, after the first control schedule 101-1 receives the system broadcast sent by the first controller 101, when a broadcast identifier is added to an Action corresponding to Intent, and when the first controller 101 is an a chip, the added identifier is fromA; when the first controller 101 is an N chip, the added identifier is fromN, so as to distinguish whether the system broadcast is sent by the chip or transmitted by the opposite-end chip.
When the first controller 101 sends the ordinary broadcast to the second controller 201, the content of the broadcast Intent does not need to add an identifier because: common broadcast is an Action with self-defined application, and in order to prevent conflict with other applications, the uniqueness of the Action is ensured, and the source of the Action cannot be distinguished after the broadcast is transmitted.
In the display device provided by the embodiment of the application, when the first controller sends the system broadcast to the second controller, the application migration only needs to add the identifier x. fromA or x. fromN to the Action corresponding to the Intent, no additional coding processing needs to be applied to the cross-system broadcast transmission, and the workload of the dual-system application migration is reduced; the modified application can also be installed on non-social television, the versatility of throw pillow power applications. When the application of the first controller sends the ordinary broadcast to the second controller, the application for receiving the secondary broadcast does not need to be modified, and only the broadcasting end needs to modify Intent according to the standard, that is, the ordinary broadcast carries a parameter Extra, and the median value of the parameter Extra is Intent sent to the second controller. Through cross-system scheduling between the broadcast of the first controller and the broadcast of the second controller, synchronization and interaction of data on dual-system display equipment are achieved, and actual experience of users is greatly improved.
