With the foregoing drawings in mind, certain embodiments of the disclosure have been shown and described in more detail below. These drawings and written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the concepts of the disclosure to those skilled in the art by reference to specific embodiments.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The HDMI device related in the present disclosure may be any device that pushes a playback resource to a playback device through an HDMI interface, for example: computers, set-top boxes, DVD players, etc. The playback device related to the present disclosure may be any device that receives the playback resource pushed by the HDMI device through the HDMI interface, for example: a television. When the HDMI device is an HDMI device other than a computer, the playback device may also be a computer.

FIG. 1 is a flow diagram illustrating a method of play matching according to an example embodiment. As shown in fig. 1, an execution subject of the method may be a playback matching apparatus, and may also be an HDMI device integrated with the playback matching apparatus, and the following description takes the execution subject as an HDMI device integrated with the playback matching apparatus (abbreviated as HDMI device) as an example, where this embodiment relates to a specific process of the HDMI device pushing a playback resource to a playback device, and the method may include the following steps:

in step S101, the EDID of the playback device is read from the playback device.

Specifically, when an HDMI interface of the HDMI device is connected to an HDMI interface of the playback device through an HDMI connection line, that is, when a Display Data Channel (DDC) is established between the HDMI device and the playback device, the HDMI device may read Extended Display Identification Data (EDID) preset in the playback device from the playback device through the DDC.

It should be noted that the EDID may be preset in the playback device by a manufacturer of the playback device when the playback device leaves a factory. The EDID may include an identification of the playback device, preset display parameters, and the like. The identifier of the playing device may include, for example: a manufacturer identification of the playback device, a playback device ID, etc. The display parameters may include: resolution, refresh frequency, etc. The preset display parameters in the EDID may include: the resolution ratios of a plurality of levels and the refresh frequency corresponding to the resolution ratios of the levels enable the playing device to adapt to the HDMI device supporting different display parameters. The level of the resolution may be referred to in the related art, and will not be described in detail.

In step S102, an inquiry message carrying the identifier of the playing device is sent to the server.

Specifically, in this embodiment, the server stores a corresponding relationship between the identifiers of the multiple playing devices and the display parameters. The corresponding relationship may reflect a display parameter matched with the playback device corresponding to the identifier of the playback device. When the HDMI device uses the display parameters matched with the playback device to push the playback resource to the playback device, the display effect of the playback device is better when playing the playback resource. The display parameters stored in the server and matched with the playing device may be the same as or different from the preset display parameters in the EDID of the playing device.

Therefore, after acquiring the identifier of the playback device, the HDMI device may send an inquiry message carrying the identifier of the playback device to the server, so as to inquire the display parameters matched with the playback device from the server.

In step S103, a first response message sent by the server in response to the query message is received.

Specifically, after receiving the query message sent by the HDMI device, the server may search for whether the identifier of the playback device exists in the stored correspondence, and when finding the identifier of the playback device, obtain the display parameter corresponding to the identifier of the playback device, and send the display parameter to the HDMI device by carrying the display parameter in the first response message.

In step S104, when the first response message indicates that the display parameter corresponding to the identifier of the playback device is matched, the playback resource is pushed to the playback device according to the display parameter matched with the identifier of the playback device included in the first response message.

Specifically, after receiving a first response message sent by the server response query message, the HDMI device may determine whether the first response message indicates that the display parameter corresponding to the identifier of the playback device is matched. If the first response message indicates that the display parameter of the identifier of the playback device is matched, the HDMI device may push the playback resource to the playback device according to the display parameter matched with the identifier of the playback device included in the first response message, so that the playback device has a better display effect when playing the playback resource. During specific implementation, the server may indicate, to the HDMI device, that the server matches the display parameter corresponding to the identifier of the playback device by sending, to the HDMI device, a first response message carrying the display parameter matched with the identifier of the playback device. The server can also send a first response message carrying the identifier agreed by both parties to the HDMI device, so that the HDMI device determines, through the identifier carried in the first response message, that the server matches the display parameter and the like corresponding to the identifier of the playback device.

Taking the HDMI device as a set-top box and the playback device as a television as an example, after the HDMI interface of the set-top box is connected with the HDMI interface of the television through an HDMI connection line, that is, after the set-top box and the television set establish a DDC, the set-top box can read EDID preset in the television by a television manufacturer from the television through the DDC. The EDID includes the manufacturer identification of the television, the ID of the television, and preset display parameters. Assume that the preset display parameters include: resolution and refresh frequency, wherein the resolution is 1080p, and the refresh frequency is 60 Hz. At this time, if the preset display parameter is not the display parameter matched with the television, when the set-top box pushes the video to the television based on the display parameter, the display effect of the television when playing the video is poor, and the user experience is low. In this embodiment, after reading the EDID of the television from the television, the set-top box may query the display parameters matched with the television from the server according to the vendor identifier of the television and the ID of the television in the EDID. Assume that the tv-matched display parameters queried in the server include a resolution of 4k2k and a refresh rate of 30 hz. Therefore, when the set top box pushes the video to the television based on the matched display parameters, namely the resolution 4k2k and the refresh frequency of 30 Hz, the display effect of the television when the video is played is better, the display effect of the television is improved, and the visual experience of a user is further improved.

Optionally, in another implementation manner of the present disclosure, the HDMI device may further push the acquired display parameters matched with the playback device and the preset display parameters in the EDID to the playback device, so that the playback device may be presented to the user through the display screen, and the user may autonomously select which display parameters the HDMI device adopts to push the playback resources to the playback device, thereby further improving user experience.

According to the playing matching method, the HDMI device can acquire the display parameters matched with the identifier of the playing device from the server according to the acquired identifier of the playing device in the EDID of the playing device, and then can push playing resources to the playing device based on the display parameters matched with the identifier of the playing device, so that the playing effect of the playing device when playing the playing resources is better, the display effect of the playing device is improved, and the visual experience of a user is improved.

Fig. 2 is a flow diagram illustrating a play matching method according to another exemplary embodiment. As shown in fig. 2, this embodiment relates to a specific process of how the HDMI device pushes a playback resource to the playback device when the display parameter matching the identifier of the playback device is not acquired from the server, and after S103, the method may further include:

in step S201, when the first response message indicates that the display parameter corresponding to the identifier of the playback device is not matched, a lowest resolution picture corresponding to the preset display parameter is obtained according to the preset display parameter of the playback device.

Specifically, after receiving the query message sent by the HDMI device, if the server does not find the identifier of the playback device in the stored correspondence, it indicates that the display parameter matched with the identifier of the playback device is not stored in the server. At this time, the first response message sent by the server to the HDMI device is used to indicate to the HDMI device that the server does not match the display parameter corresponding to the identifier of the playback device. In a specific implementation, the server may indicate, to the HDMI device, that the server does not match the display parameter corresponding to the identifier of the playback device by sending a blank first response message to the HDMI device. The server may also send a first response message carrying the identifier agreed by both parties to the HDMI device, so that the HDMI device determines, through the identifier carried in the first response message, that the server does not match the display parameter corresponding to the identifier of the playback device.

As described in the foregoing embodiment, the display parameters preset in the EDID of the playback device may include: the resolution of a plurality of levels and the refresh frequency corresponding to the resolution of the level. Therefore, when the HDMI device determines that the server does not match the display parameter corresponding to the identifier of the playback device according to the first response message, the HDMI device may obtain a lowest resolution picture corresponding to the preset display parameter according to the lowest level resolution in the preset display parameter. The picture with the lowest resolution may be a picture in a playback resource to be pushed to the playback device by the HDMI device, or a preset picture in the HDMI device.

In step S202, the lowest resolution picture is pushed to the playback device.

Specifically, after the HDMI device acquires the lowest resolution picture corresponding to the preset display parameter, the HDMI device may push the lowest resolution picture to the playback device, so that the playback device displays the lowest resolution picture to the user.

In step S203, an adjustment instruction input by the user according to the lowest resolution screen is acquired.

Specifically, after the user sees the lowest resolution picture on the playback device, if the user is not satisfied with the resolution of the currently displayed picture, the user may send an adjustment instruction to the HDMI device to instruct the HDMI device to obtain the optimal display parameters of the playback device. Optionally, in another implementation manner of the present disclosure, the lowest resolution picture pushed to the playback device by the HDMI device may carry prompt information to prompt a user whether to input an adjustment instruction, so as to further improve user experience.

During specific implementation, a user can send an adjustment instruction to the HDMI device through a remote controller for controlling the HDMI device, and the user can also send a control instruction to the HDMI device through a control button arranged on the HDMI device. The user can also send control instructions and the like to the HDMI device through a control screen on the HDMI device.

In step S204, according to the adjustment instruction, the optimal display parameters of the playback device are obtained.

Specifically, after receiving the adjustment instruction, the HDMI device may sequentially push, according to the levels of resolution in the related art and in the order from low to high of the levels, the picture corresponding to each level to the playback device from a resolution greater than the resolution corresponding to the lowest resolution picture until receiving a display error instruction input by a user, where the display error instruction is used to indicate that the currently displayed picture is not normal to the HDMI device. After receiving the display error instruction sent by the HDMI device, the HDMI device may use a display parameter corresponding to a resolution lower than the resolution of the picture indicated by the display error instruction as the optimal display parameter of the playback device, so that the HDMI device may push the playback resource to the playback device based on the optimal display parameter, so that the playback device has a better display effect when playing the playback resource, the display effect of the playback device is improved, and the visual experience of the user is improved.

Illustratively, assume that the resolutions are, in order of rank bottom to top: 720p, 1080p, 4k2 k. At this time, the resolution corresponding to the lowest resolution picture pushed by the HDMI to the playback device is: 720 p. The HDMI device may push a 1080p resolution picture to the playback device from 1080p first after receiving the adjustment instruction, so that the playback device can display the 1080p resolution picture to the user. If the HDMI device does not receive a display error instruction input by the user during the pushing of the 1080p resolution picture, the HDMI device may continue to push the 4k2k resolution picture to the playback device so that the playback device may display the 4k2k resolution picture to the user. If the HDMI device does not receive the display error command from the user during the pushing of the 4k2k resolution frame, the HDMI device uses the display parameters corresponding to the 4k2k resolution as the optimal display parameters for the playback device. If during the pushing of the 4k2k resolution picture, the HDMI device receives a display error instruction input by the user, and then the HDMI device takes the display parameter corresponding to the 1080p resolution as the optimal display parameter of the playback device, so that the HDMI device can push the playback resource to the playback device based on the optimal display parameter, so that the display effect of the playback device when playing the playback resource is better, the display effect of the playback device is improved, and the visual experience of the user is improved. At this time, the display parameter is the display parameter matched with the playing device.

Furthermore, the HDMI device may further send a parameter addition request to the server, so that the optimal display parameter and the identifier of the playback device are carried in the addition request and sent to the server, and the server establishes a corresponding relationship between the identifier of the playback device and the optimal display parameter based on the addition request, thereby expanding the storage capacity of the server. Therefore, other HDMI devices can quickly acquire the display parameters matched with the playing device from the server, and the efficiency of acquiring the display parameters matched with the playing device by the other HDMI devices is improved.

According to the play matching method, the HDMI device can acquire the optimal display parameter of the playing device according to the acquired identifier of the playing device in the EDID of the playing device when the display parameter matched with the identifier of the playing device is not acquired from the server, and then can push the playing resource to the playing device based on the optimal display parameter, so that the playing device has a better display effect when playing the playing resource, the display effect of the playing device is improved, and the visual experience of a user is improved.

Further, the lowest resolution picture pushed to the playback device by the HDMI device may carry query information to query whether the user needs to input an adjustment instruction. Meanwhile, the query information may also carry a type list of type information that enables the user to select the playback device, or the query information may also carry information that prompts the user to input the type information of the playback device, so that the user may carry the type information of the playback device selected or input in the input adjustment instruction. And then the HDMI device can acquire the type information of the playing device based on the adjustment instruction input by the user. Optionally, in another implementation manner of the present disclosure, the HDMI device may further directly push the query information to the playback device when the first response message indicates that the display parameter of the identifier of the playback device is not matched, so as to query whether the user needs to input the adjustment instruction through a display screen of the playback device. When the user inputs the adjustment instruction, the HDMI device can directly acquire the adjustment instruction input by the user when the first response message indicates that the display parameter of the identifier of the playing device is not matched, and the efficiency of the HDMI device for acquiring the adjustment instruction is improved.

Fig. 3 is a flowchart illustrating a play matching method according to yet another exemplary embodiment. As shown in fig. 3, based on the foregoing embodiment, the present embodiment relates to a specific process of the HDMI device acquiring the optimal display parameter of the playback device according to the adjustment instruction, and then in S204, the specific process may include:

in step S301, a matching request carrying the type information of the playing device is sent to the server according to the adjustment instruction.

Specifically, in this embodiment, the server may further store a second display parameter corresponding to the type information of the playback device. The second display parameter may be suitable for playback devices produced by all manufacturers corresponding to the type of information.

Therefore, after receiving the adjustment instruction input by the user, the HDMI device may send a matching request carrying the type information of the playback device to the server according to the type information of the playback device input by the user or selected by the user, so as to instruct the server to perform fuzzy matching according to the type information of the playback device, so as to obtain the second display parameter suitable for the playback device. The type information of the playback device may be, for example, the size of the display screen of the playback device, the type of the display screen of the playback device, and the like.

In step S302, a second response message sent by the server in response to the matching request is received.

Specifically, after receiving the matching request sent by the HDMI device, the server may search for whether the type information of the playback device exists in the corresponding relationship stored in the server, and further, when the type information of the playback device is found, obtain a second display parameter corresponding to the type information of the playback device, and send the HDMI device with the second display parameter in a second response message.

In step S303, when the second response message indicates that the second display parameter corresponding to the type information of the playback device is matched, the optimal display parameter of the playback device is obtained according to the second display parameter corresponding to the type information of the playback device and the preset display parameter included in the second response message.

Specifically, after receiving a second response message sent by the server, the HDMI device may determine whether the second response message indicates that the second display parameter corresponding to the type information of the playback device is matched. During specific implementation, the server may indicate, to the HDMI device, that the server matches the second display parameter corresponding to the type information of the playback device by sending a second response message carrying the second display parameter to the HDMI device. The server may further send a second response message carrying the identifier agreed by both parties to the HDMI device, so that the HDMI device determines, through the identifier carried in the second response message, that the server matches the second display parameter and the like corresponding to the type information of the playback device.

When the response message indicates that the second display parameter corresponding to the type information of the playback device is matched, the HDMI device may obtain the optimal display parameter of the playback device according to the second display parameter corresponding to the type information of the playback device and the preset display parameter included in the second response message.

Optionally, the HDMI device may sequentially push the playing resources to the playing device according to the second display parameter and the sequence of the preset display parameters from high to low, and according to the display parameters, until the playing device correctly displays the playing picture corresponding to the playing resource. At this time, the HDMI device may use the display parameter corresponding to the correctly displayed playback resource as the optimal display parameter of the playback device. For example: the preset display parameters include a display parameter 1 and a display parameter 2, wherein the second display parameter, the display parameter 2 and the display parameter 1 are the second display parameter and the preset display parameter in sequence from high to low. At this time, the HDMI device may first push the playback resource to the playback device according to the second display parameter. If the HDMI device does not receive a display error instruction input by the user during the period of pushing the playback resource to the playback device according to the second display parameter, the HDMI device may use the second display parameter as the optimal display parameter of the playback device. If the HDMI device receives the display error instruction input by the user, which indicates that the playback device cannot normally play the playback resource when playing the playback resource corresponding to the second display parameter, for example: abnormal display scale, no picture visible to the user, etc. That is, the second display parameter does not match the playback device, and therefore, the HDMI device can push the playback resource to the playback device according to the display parameter 2. If the HDMI device does not receive a display error instruction input by the user during the period of pushing the playback resource to the playback device according to the display parameter 2, the HDMI device may use the display parameter 2 as the optimal display parameter of the playback device. If the HDMI device receives a display error instruction input by the user, it indicates that the display parameter 2 is not matched with the playback device, so that the HDMI device can push a playback resource to the playback device according to the display parameter 1, and use the display parameter 1 as an optimal display parameter of the playback device. At this moment, when the HDMI device pushes the playing resource to the playing device based on the optimal display parameter, the playing device has an optimal display effect when playing the playing resource, so that the display effect of the playing device is improved, and the visual experience of the user is further improved.

Optionally, the HDMI device may further sequentially push the playing resources to the playing device according to the second display parameter and the sequence of the preset display parameters from low to high, and according to the display parameters, until the playing device cannot correctly display the playing picture corresponding to the playing resource. At this time, the HDMI device may use the display parameter corresponding to the played back resource that is "before the played back resource that cannot be correctly displayed is pushed" as the optimal display parameter of the HDMI device. The implementation manner of the method is similar to the above-mentioned manner of "sequentially pushing the playing resources to the playing device according to the display parameters in the second display parameter and the preset display parameter from high to low, and according to the display parameters", which is not described again.

Optionally, in an implementation manner of the present disclosure, when the HDMI device pushes a playing resource to the playing device based on the optimal display parameter, the HDMI device may further carry an inquiry message about whether to use the optimal display parameter in the playing resource, so that the display screen of the playing device may display the inquiry message, and then the user may determine whether to continue to use the optimal display parameter according to a display effect when the playing device plays the playing resource, thereby improving user experience. Further, if the user returns a response message to the HDMI device to continue using the optimal display parameters based on the query message, it is indicated that the optimal display parameters are the display parameters matched with the playback device. At this time, the HDMI device may further send a parameter addition request to the server, so as to carry the optimal display parameter and the identifier of the playback device in the addition request and send the addition request to the server, thereby enabling the server to establish a corresponding relationship between the identifier of the playback device and the optimal display parameter based on the addition request, and expanding the storage capacity of the server. Therefore, other HDMI devices can quickly acquire the display parameters matched with the playing device from the server, and the efficiency of acquiring the display parameters matched with the playing device by the other HDMI devices is improved.

According to the play matching method, the HDMI device can acquire the second display parameter of the playing device from the server based on the adjustment instruction of the user when the display parameter matched with the identifier of the playing device is not acquired from the server according to the acquired identifier of the playing device in the EDID of the playing device, and further can acquire the optimal display parameter based on the second display parameter and the preset display parameter, so that the HDMI device can push the playing resource to the playing device based on the optimal display parameter, the playing device plays the playing resource with a better display effect, the display effect of the playing device is improved, and the visual experience of the user is improved.

The following describes in detail the play matching method provided by the present disclosure, taking HDMI devices as set-top boxes and playback devices as television sets as examples. Fig. 4 is a signaling flow diagram illustrating a play matching method according to yet another exemplary embodiment. As shown in fig. 4, the method may include:

in step S401, the set-top box reads the EDID of the television from the television.

The EDID may be preset in the television when the television is shipped from a television manufacturer. The EDID may include an identification of the television, preset display parameters, and the like. Wherein, the identification of the television comprises: television manufacturer identification, television ID, etc. The display parameters may include: resolution, refresh frequency, etc. The preset display parameters in the EDID may include: the television comprises a plurality of levels of resolution and refresh frequencies corresponding to the levels of resolution, so that the television can be adapted to set-top boxes supporting different display parameters. The level of the resolution may be referred to in the related art, and will not be described in detail.

In step S402, the set-top box sends a query message carrying the identifier of the television to the server.

In step S403, the set top box receives a first response message sent by the server in response to the query message.

In step S404, the set-top box determines whether the first response message indicates that the display parameter corresponding to the identifier of the television is matched. If yes, go to step S405, otherwise, go to step S406.

In step S405, when the first response message indicates that the display parameter corresponding to the identifier of the television is matched, and the set-top box pushes the play resource to the television according to the display parameter matched with the identifier of the television included in the response message.

Optionally, when the response message includes the display parameter matched with the identifier of the television, the set-top box may further push the display parameter matched with the acquired identifier of the television and the preset display parameter in the EDID to the television, so that the television may be presented to the user through the display screen, and the user may autonomously select which display parameter is adopted by the set-top box to push the playing resource to the television. During specific implementation, a user can input a selection instruction to the set top box in a mode of selecting a certain display parameter through a remote controller of the set top box so as to indicate which display parameter is adopted by the set top box to push playing resources to a television, and user experience is further improved.

In step S406, when the first response message indicates that the display parameter corresponding to the identifier of the television is not matched, the set top box acquires a lowest resolution picture corresponding to the preset display parameter according to the preset display parameter of the television.

In step S407, the set-top box pushes the lowest resolution picture to the television.

In step S408, the set-top box acquires an adjustment instruction input by the user according to the lowest resolution picture.

Specifically, when the set-top box pushes the lowest resolution picture to the television, the set-top box can also push inquiry information to the television to inquire whether the user needs to input an adjustment instruction. The query information may carry a type list of type information that enables the user to select the television, or the query information may also carry information that prompts the user to input the type information of the television, so that the set-top box may obtain the type information of the television based on the operation of the user. The type information of the television may be a size of the television, a kind of a display screen of the television, and the like.

Optionally, in another implementation manner of the present disclosure, the set top box may further directly push the query information to the television when the first response message indicates that the display parameter of the identifier of the television is not matched, so as to query whether the user needs to input the adjustment instruction through a display screen of the television. And when the user inputs the adjusting instruction, the set-top box can directly acquire the adjusting instruction input by the user when the first response message indicates that the display parameter of the identifier of the television is not matched, so that the efficiency of acquiring the adjusting instruction by the set-top box is improved. Namely, the above-mentioned S406-S408 can be replaced by the following steps:

and when the first response message indicates that the display parameters corresponding to the television identification are not matched, the set top box acquires an adjusting instruction input by the user.

In step S409, the set-top box sends a matching request carrying the type information of the television to the server according to the adjustment instruction.

In step S410, the set-top box receives a second response message sent by the server in response to the matching request.

Specifically, the server fuzzily matches a second display parameter of the television to the television through the type information of the television, and carries the second display parameter in a second response message to send to the set top box.

In step S411, when the second response message indicates that the second display parameter corresponding to the type information of the television is matched, the set-top box sequentially pushes the playing resource to the television according to the display parameters in the second display parameter and the preset display parameter from high to low until the television correctly displays the playing picture corresponding to the playing resource, and uses the display parameter corresponding to the correctly displayed playing resource as the optimal display parameter of the playing device.

In step S412, the set-top box pushes the playing resource to the television according to the optimal display parameter.

In step S413, the set-top box transmits a parameter addition request to the server.

Wherein the parameter addition request comprises: identification of the television, and optimal display parameters.

Specifically, when the set-top box pushes the playing resource to the television based on the optimal display parameter, the set-top box may further carry an inquiry message about whether to adopt the optimal display parameter in the playing resource, so that the display screen of the television may display the inquiry message, and then the user may determine whether to continue to use the optimal display parameter according to the display effect when the playing resource is played by the television, thereby improving user experience. If the user returns a response message for continuously using the optimal display parameter to the set-top box based on the inquiry message, the optimal display parameter is the display parameter matched with the television. At this time, the set top box may send a parameter addition request to the server to carry the optimal display parameter and the identifier of the television in the addition request and send the addition request to the server, so that the server establishes a corresponding relationship between the identifier of the television and the optimal display parameter based on the addition request, thereby expanding the storage capacity of the server. Therefore, other set top boxes can quickly acquire the display parameters matched with the television from the server, and the efficiency of acquiring the display parameters matched with the television by other set top boxes is improved.

According to the playing matching method, the set top box can acquire the display parameters really matched with the television according to the acquired television identification in the EDID of the television, and then can push the playing resources to the television based on the display parameters, so that the display effect of the television when the playing resources are played is better, the display effect of the television is improved, and the visual experience of a user is improved.
