Technical Field
The present disclosure relates to the field of communications technologies, and in particular, to a multi-screen interaction method, an apparatus, and a terminal.
Background
With the continuous development of the smart television, the multi-screen interaction function between the mobile terminal and the smart television is also endless. At present, media resources stored on a mobile terminal are mainly pushed to an intelligent television through a standard DLNA (Digital Living Network Alliance) protocol for playing, and media sharing is realized between the mobile terminal and the intelligent television.
With the rapid development of mobile terminals, more and more functions (such as a screen capture function, a screen recording function, etc.) can be performed by the mobile terminals on the basis of playing and sharing. For this reason, the smart tv also needs to update the system to be compatible with more different interactive functions. At present, a smart television usually updates a system in an OTA (Over-the-Air technology) upgrading mode, a manufacturer releases a new version or a part of new functions in an upgrade package, and after a user downloads the upgrade package on line, the smart television can automatically decompress to a corresponding directory to cover an original file, so as to realize system updating.
However, the OTA upgrade is a planned upgrade mode, the update frequency is low, and the time interval is long; in addition, many users cannot actively download the upgrade package due to various reasons, so that the updating process of the intelligent television system is delayed, the intelligent televisions with different platforms and models have great difference in functions, and the difficulty in adapting the mobile terminal and the television terminal is increased. For example, in a technical scene that a mobile terminal is configured with a function key for screen capture, but a television terminal performing multi-screen interaction with the mobile terminal does not support the screen capture function, the television terminal cannot respond to the trigger operation of a user on the screen capture function key. However, at this time, the user cannot determine the actual reason for the non-response of the television terminal, that is, cannot distinguish whether the television non-response key is the reason for the user operation, the reason for the wrong television receiving instruction, or the reason for the television configuration, so that the experience of the user on the multi-screen interactive operation is reduced.

Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Due to the fact that the functions of the smart televisions are greatly different, when the smart televisions are subjected to multi-screen interaction, the mobile terminal is difficult to be compatible with the smart televisions with all platforms and models by configuring multi-screen interaction software, and software design cost of the mobile terminal is increased greatly. On the other hand, because the mobile terminal cannot know the version update condition of the television terminal, when the television terminal performs the version update (for example, a screen switching function is added), the multi-screen interaction software fixed on the mobile terminal cannot be adapted to the new version of the television terminal. In this case, the user cannot learn and use the new function at the first time, which degrades the user experience.
Aiming at the problems that when multi-screen interaction is carried out, the mobile terminal and a television terminal platform are poor in compatibility, and user experience is reduced, the multi-screen interaction method, the multi-screen interaction device and the multi-screen interaction terminal are provided, the method can be applied to the television terminal and the mobile terminal respectively, and the core idea is as follows: adding an automatically updated configuration file in the television terminal, wherein the configuration file comprises a plurality of configuration items for recording the attributes of the television terminal; when the mobile terminal and the television terminal are subjected to multi-screen interaction, the television terminal expands standard response information of a discovery command based on a DLNA protocol, integrates each configuration item of the television terminal with the standard response information, and feeds the integrated expanded response information back to the mobile terminal. The present invention will be further described with reference to the following detailed description and the accompanying drawings.
The embodiment provides a multi-screen interaction method which is applied to a television terminal. Referring to fig. 1, a flowchart of a multi-screen interaction method according to an embodiment of the present disclosure is shown. As can be seen from fig. 1, the method comprises:
step S100: and modifying a configuration file configured in the television terminal based on the update content corresponding to the television software version update, wherein the configuration file at least comprises a platform model configuration item, a support protocol configuration item and a support function configuration item of the television terminal.
In this embodiment, the television terminal is configured to be capable of automatically detecting the version model issued on the corresponding server, and automatically updating the configuration file according to a comparison result between the version model of the television terminal and the version model issued on the server. Specifically, please refer to fig. 2, which shows a flowchart of a method of step S100 according to an embodiment of the present application. As can be seen from fig. 2, step S100 includes:
step S101: and acquiring the version serial number of the multi-screen interaction program on the television terminal server.
Step S102: and comparing the version number on the television terminal server with the version number built in the television terminal, and executing the step S103 if the version number built in the television terminal is lower than the version number on the television terminal server.
Step S103: and acquiring a multi-screen interaction program stored on the television terminal server, and storing configuration items built in the multi-screen interaction program into the configuration file, so that original configuration items in the configuration file are covered, and self-upgrading is realized.
For example, if the protocol type is modified by the new version of the multi-screen interactive program, the configuration file before modification is:
DLNA_LIST@\nconf_version＝1.0\ntransport_protocol＝1\nplatform＝2\nremote_type＝2\nemanual＝0\n
network_wakeup＝0\ninput＝1\nvoice＝1\nwire＝1\ncap＝1\nsetname＝1\nnumerickey＝1\n@DLNA_LIST_END；
the configuration file before modification is as follows:
DLNA_LIST@\nconf_version＝1.0\ntransport_protocol＝2\nplatform＝2\nremote_type＝2\nemanual＝0\n
network_wakeup＝0\ninput＝1\nvoice＝1\nwire＝1\ncap＝1\nsetname＝1\nnumerickey＝1\n@DLNA_LIST_END。
step S200: when a discovery command sent by the mobile terminal is detected, integrating the configuration item information in the configuration file and the standard response information in the DLNA protocol into extended response information, and feeding back the extended response information to the mobile terminal so that the mobile terminal can adapt according to the extended response information.
In this embodiment, a DLNA module of the television terminal is started when monitoring a start broadcast, reads the content of the configuration file through the data/favorite directory, and intercepts configuration item information between DLNA _ LIST @ and @ DLNA _ LIST _ END in the configuration file:
\nconf_version＝1.0\ntransport_protocol＝2\nplatform＝2\nremote_type＝2\nemanual＝0\n
network_wakeup＝0\ninput＝1\nvoice＝1\nwire＝1\ncap＝1\nsetname＝1\nnumerickey＝1\。
when the television terminal detects a discovery command sent by the mobile terminal, the configuration item information and standard response information in a DLNA protocol are spliced into extended response information, and the extended response information is fed back to the mobile terminal, so that the mobile terminal can know the latest configuration item information of the television terminal performing multi-screen interaction with the mobile terminal and adapt according to the configuration item information.
The specific form of the standard response message is as follows:
Type＝1\ndevice_id＝uuid:aa15c5a0-998f-11db-91f7-2dd1bf685f2d\n
hostname＝http://192.168.1.157:38400/MediaServer/rendererdevicedesc.xml。
the specific form of the extended response information is as follows:
Type＝1\ndevice_id＝uuid:aa15c5a0-998f-11db-91f7-2dd1bf685f2d\n
hostname＝http://192.168.1.157:38400/MediaServer/rendererdevicedesc.xml\n
modeldescription＝#CAP#mac＝94e9792caf6c\nip＝192.168.1.157\nconf_version＝1.0\n
transport_protocol＝1\nplatform＝2\nremote_type＝2\nemanual＝0\n
network_wakeup＝0\ninput＝1\nvoice＝1\nwire＝1\ncap＝1\nsetname＝1\nnumerickey＝1\n。
the method comprises the steps that a configuration file capable of being automatically updated is additionally arranged on a television terminal, wherein the configuration file comprises a plurality of configuration items for recording the attributes of the television terminal; when the mobile terminal and the television terminal are subjected to multi-screen interaction, the television terminal expands standard response information of a discovery command based on a DLNA protocol, integrates each configuration item of the television terminal with the standard response information, and feeds the integrated expanded response information back to the mobile terminal.
In addition, referring to fig. 3, in other embodiments of the present application, before step S100, the method further includes:
step S010: detecting whether a first configuration file with a writable attribute exists;
step S020: if yes, detecting whether the current television software version is updated;
step S030: if the current television software version does not exist, the non-writable second configuration file preset by the television terminal is saved as the first configuration file with the writable attribute, and whether the current television software version is updated or not is detected.
The configuration file includes a platform model configuration item, a support protocol configuration item, and a support function configuration item of the television terminal, and may also include configuration item information such as an IP address, a device name, and a max address. The configuration file in the embodiment has a writeable attribute, and can be automatically updated in subsequent steps. The specific form of the configuration file may be as follows:
DLNA_LIST@\nconf_version＝1.0\ntransport_protocol＝1\nplatform＝2\nremote_type＝2\nemanual＝0\n
network _ wakeup is 0\ input is 1\ nwice is 1\ ncap is 1\ nsetname is 1\ nnumerickey is n @ DLNA _ LIST _ END. The information between DLNA _ LIST @ and @ DLNA _ LIST _ END is a configuration item capable of representing the configuration attribute of the television terminal, and the conf _ version represents the version of the configuration file; transport _ protocol represents the protocol type supported by the television side; the platform represents the platform type of the television; remote _ type represents a supported remote controller type; the email indicates whether the electronic specification is supported; network _ wakeup indicates whether wifi wakeup is supported; input indicates whether an input method is supported; the functional items such as wifi awakening and input methods are represented as support by 1, and are not supported by 0, and if no corresponding configuration item exists, the function items are not supported by default; the settings of protocol type, platform type, etc. are represented with 1, 2, 3.
In this embodiment, a writeable file may be directly stored in/under the data/service directory of the television terminal as a configuration file, so that when a version update is detected, only the updated configuration item needs to be overwritten with the stored configuration file.
However, some television terminals with lower versions still exist in the current market, and a configuration file a is preset in the television terminal under a directory system/etc, and the configuration file a also contains the above configuration information, but is usually a non-writeable file, cannot be automatically updated in the subsequent process, and needs to be saved as a writeable configuration file B, so as to perform the subsequent updating process. In view of the above situation, the present application further provides a method for setting a configuration file with writable attributes, so as to be compatible with more types and versions of television terminals.
In this embodiment, the second configuration file is the configuration file a, the first configuration file is the configuration file B, when a multi-screen interactive service (Hiservice) of the television terminal is started, the second configuration file is read, and the content of the second configuration file is copied to the first configuration file, at this time, the content of the first configuration file is consistent with that of the second configuration file, and the first configuration file is stored in a directory/data/Hiservice.
Corresponding to the above embodiments, the present embodiment further provides a third multi-screen interaction method, which is applied to a mobile terminal. Referring to fig. 4, a flowchart of another multi-screen interaction method according to an embodiment of the present application is shown. As can be seen from fig. 4, the method comprises:
step S10: and sending a discovery command to the television terminal.
Step S20: analyzing the extended response information sent by the television terminal, and extracting configuration items in the extended response information.
Step S30: and adapting a user interface, a protocol interface and a function entrance of a multi-screen interaction program according to the configuration item.
After receiving the extended response information, the mobile terminal intercepts the content behind the # CAP #, and then analyzes the specific support capability of the television terminal according to different fields. For example, if "voice" can be read, the following bit of "voice" is continuously read, and if "voice" is 1, the television platform is recorded to support voice; if the next bit is 0, then the television platform is not voice enabled. If the 'cap' can be read, the 'cap' is continuously read as the next bit, if the 'cap' is 1, the fact that the television platform supports screen capture is recorded, otherwise, screen capture is not supported. If "platform" can be read, then "platform" is read again, if 1, the television terminal is recorded as an out-selling television, if 2, the television terminal is recorded as an in-selling television, and then "platform" can be set to 3, 4, 5, etc. next, so as to continue to expand other platforms. If the "transport _ protocol" can be read, then the "transport _ protocol" is read, if the "transport _ protocol" is 1, the television terminal is recorded to support the mqtt protocol, if the "transport _ protocol" is 2, the television terminal is recorded to support the private protocol, and then the "transport _ protocol" can be set to 3, 4, 5 and the like, so that other protocols can be continuously extended.
The mobile terminal adapts the user interface, the protocol interface, the function entry and the like of the multi-screen interaction program according to the extracted configuration items so as to facilitate the smooth operation of the multi-screen interaction function, and meanwhile, the mobile terminal can show the adaptive interface and function entry in combination with the configuration of the television terminal so that the user can clearly judge the function attribute supported by the television terminal. For example, if the interactive television terminal analyzed by the mobile terminal is a foreign marketing television, the user interface is adapted to a foreign style theme interface, and if the interactive television terminal analyzed by the mobile terminal is a domestic marketing television, the user interface is adapted to a domestic style theme interface. In addition, the mobile terminal can hide functions which are not supported by the television terminal so as to prevent misleading users. For example, if the television terminal does not support the voice function, the voice entry will not be displayed on the mobile terminal, and so will the other functions.
