Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a video playing method, executed in a terminal device, including:
104, determining a connection state of the first display device and the signal processing device based on the second resolution and the third resolution;
and 105, instructing the first display device to play a first video based on the connection state.
In this embodiment, the video playing method may be applied to any terminal device with a communication function, for example: a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
It should be understood that the signal processing device may be a television box, a set-top box, or the like, and the first display device may be understood as a television, and the television includes a screen projection module supporting a standard protocol, such as Digital Living Network Alliance (DLNA). In the case that the tv box is connected to a tv (e.g. connected via a High Definition Multimedia Interface (HDMI)), the resolution of the tv box is the resolution of the tv connected to the tv box.
It should be understood that Extended Display Identification Data (EDID) is a standard for Display Identification Data that is established by Video Electronics Standards Association (VESA) when a Display Data Channel (DDC) communication protocol is established. In the embodiment of the present invention, i.e., EDID is stored in the DDC memory of the first display device, in the case where the signal processing apparatus is connected to the first display device, the signal processing apparatus reads the EDID stored in the DDC memory of the first display device through the DDC.
The first resolution obtained in step 101 is a resolution in the EDID currently read by the signal processing device, that is, the EDID read by the signal processing device is an EDID of a display device currently connected to the signal processing device, and the first resolution is a resolution at which a video is played by a display device currently connected to the signal processing device; the second resolution obtained in step 103 is the resolution in the EDID read by the signal processing device when the first display device plays the video with the second resolution.
For example: taking the signal processing device as device a, the first display device as device B, and the device currently connected to the signal processing device as device C as examples, acquiring the first EDID of device a, that is, reading the EDID of device C through device a, that is, acquiring the first resolution as the resolution of the video currently displayed by device C; and under the condition that the device B plays the video at the second resolution based on the video playing control instruction, acquiring the second EDID of the device A, namely reading the EDID of the device C through the device A, namely, when the acquired third resolution is the video played by the device B at the second resolution, displaying the video resolution by the device C. It can be understood that the determination of whether the signal processing device (device a) and the first display device (device B) are in the connected state is a determination of whether the device C and the device B are the same device, and if the third resolution is consistent with the second resolution, it may be determined that the device B and the device C are the same device, that is, the device B and the device a are in the connected state.
It should be understood that, if the third resolution is identical to the second resolution, that is, the current resolution of the signal processing device is changed from the first resolution to the second resolution after the step 102 is executed and the current resolution of the first display device is changed to the second resolution, it may be considered that the resolution of the signal processing device is identical to the resolution of the first display device, and thus the first display device is connected to the signal processing device. If the third resolution is different from the second resolution, the resolution of the first display device is not related to the resolution of the signal processing device, and it may be considered that the first display device is not connected to the signal processing device.
It should be understood that there may be a plurality of signal processing apparatuses, and when determining whether the signal processing apparatus and the first display apparatus are in a connected state, the plurality of signal processing apparatuses may be determined individually or collectively.
For example: in the case where there are two signal processing devices, device D and device E, taking the respective determinations for the above multiple signal devices as an example: the connection states of the device D and the device E with the first display device may be respectively determined using the steps 101 to 104, so as to respectively obtain a result of whether the device D is connected with the first display device and a result of whether the device E is connected with the first display device, and the determination processes of the device D and the device E may be performed simultaneously or sequentially; taking the common determination of the multiple signal devices as an example, the resolution of the device D and the resolution of the device E may be obtained in the step 101, respectively, and in the step 102, it may be understood that the second resolution is different from both the resolution of the device D and the resolution of the device E, so that when determining the connection state between the device D and the first display device, the determination as to whether the resolution of the device D and the resolution of the device E change with the resolution of the first display device may be implemented, that is, the connection state between the device D and the first display device may be obtained simultaneously.
It should be understood that whether the first display device plays the video at the second resolution may be determined by the feedback result sent by the first display device in response to the video playing control command, or the first display device may default to play the video at the second resolution after sending the video playing control command to the first display device for a preset time (e.g., 3 seconds, 10 seconds, etc.). In this way, the obtaining of the second EDID of the signal processing device in step 103 may be performed after receiving a response of playing the video at the second resolution sent by the first display device, or may be performed after a preset time of executing step 102, or may actively obtain the current resolution of the first display device at a preset time interval after executing step 102.
It should be understood that after the connection state between the first display device and the signal processing device is determined, if the first display device is connected to the signal processing device, no matter a first video is projected to the first display device or projected to the signal processing device, the first video can be played through the first display device, so that when the scenario to be switched, the resolution to be switched, the played video and the like are limited in copyright, the first video can be played through switching between the first display device and the signal processing device. The first video may be a next episode of a currently played video of the first display device, a video with a different resolution of the currently played video, or another video that is projected by a user.
In the video playing method provided by the embodiment of the present invention, first extended display identification data EDID of a signal processing device is obtained, where the first EDID includes a first resolution. Secondly, a video playing control instruction is sent to a first display device based on the first resolution, the video playing control instruction is used for instructing the first display device to play a video with a second resolution, and the second resolution is different from the first resolution. Then, in a case where the first display device plays the video at the second resolution, a second EDID of the signal processing device is acquired, the second EDID including the third resolution. Further, a connection state of the first display device and the signal processing device is determined based on the second resolution and the third resolution. And finally, based on the connection state, instructing the first display device to play a first video. In the method, EDID of the signal processing device before and after sending a video playing control instruction to the first display device is respectively obtained, and based on the comparison between the second resolution and the third resolution, whether the current resolution of the signal processing device is consistent with the first display device is determined, that is, whether the resolution of the signal processing device changes with the change of the resolution of the first display device is determined, which is used as a basis for determining whether the signal processing device is connected to the first display device, and the connection state of the first display device and the signal processing device is determined, and when the conditions of episode switching, resolution switching, video playing and the like meet copyright restrictions, the playing of the first video can be realized based on the connection state of the first display device and the signal processing device.
In addition, the method determines the connection state of the first display device and the signal processing device based on whether the resolution of the signal processing device changes with the change of the resolution of the first display device. The resolution of the first display device may be controlled to change for a plurality of times by the video playing control instruction, and the video playing control instruction is compared with the resolution of the signal processing device after each change, so as to verify whether the resolution of the signal processing device changes dynamically with the change of the resolution of the first display device for a plurality of times, thereby improving the accuracy of determining the connection state.
Optionally, the video playback control instruction includes:
a second screen projection instruction, wherein the second screen projection instruction comprises the second resolution and second video data, and the second screen projection instruction is used for instructing the first display device to play a second video at the second resolution; or the like, or, alternatively,

It should be understood that, for a video without copyright, the first display device cannot be played, and the video without copyright includes situations such as no video playing copyright, no copyright for some episodes in the video, or no copyright for some resolutions in the video, so that when the first display device plays the video, there may be a situation that it is difficult to play smoothly due to no copyright notice, and if the devices such as a television box and a set-top box connected to the first display device have corresponding copyright at this time, the video can be played through the devices such as a television box and a set-top box connected to the first display device.
The acquired first copyright information of the first display device may be all video information of which the first display device has a copyright, or may specifically acquire copyright information related to a video to be screened, for example: when the first display device has copyright to the video a, the video B and the video C, and the video to be projected is the video D, the information of the video a, the video B and the video C may be acquired, or only the information of the video D may be acquired in the embodiment of the present invention. In this way, in the case of sending a screen-casting instruction to the first display device, it may be determined whether the first display device has a copyright of the video D by the acquired information of the video a, the video B, and the video C or the acquired information of the video D. Similarly, the second copyright information of the signal processing device may be all video information of the first display device with copyright, and may also be obtained in a targeted manner from the copyright information related to the video to be projected, and the specific obtaining manner may refer to the obtaining manner of the first display device, which is not described herein again.
It should be understood that the terminal device may send a copyright query request to the first display device to obtain which videos the first display device has, or to obtain whether the first display device has the copyright of the first video. Of course, the terminal device may also send a copyright query request to the signal processing device to obtain the copyright of which video the signal processing device has, or obtain whether the signal processing device has the copyright of the first video.
