The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 2 is a schematic flowchart of a play control method in an audio/video play system according to an embodiment of the present invention. The method is suitable for the situation that the playing equipment is switched to play the network audio and video data which is downloaded from the internet and is the same as the Bluetooth audio and video data from the playing sound source equipment, and can be executed by a playing control device in an audio and video playing system. The device can be realized by software and/or hardware and can be configured in a playing device which establishes Bluetooth connection with an audio source device. As shown in fig. 2, the method includes:
step 101, when a preset playing switching condition is detected, downloading network audio and video data corresponding to a current audio and video according to current audio and video information of the current audio and video corresponding to Bluetooth audio and video data sent by a sound source device and received by the current playing device.
The audio source device of the present invention is a device that can output audio and/or video data.
The audio/video information may include information related to the song as much as possible, such as the title of the song, the album, the singer, and the like, so that the network audio/video data downloaded by the current playing device is completely the same as the bluetooth audio/video data. The preset play switching condition may include:
the Bluetooth signal intensity of the sound source equipment is smaller than a preset Bluetooth signal intensity threshold value; or,
the packet loss rate of a Bluetooth transmission path between the current playing equipment and the sound source equipment is greater than a preset packet loss rate threshold value; or,
the error rate of the Bluetooth transmission path between the current playing equipment and the sound source equipment is larger than a preset error rate threshold value.
The preset Bluetooth signal intensity threshold, the preset packet loss rate threshold and the preset error rate threshold can be set to be a normal value close to an abnormal value, so that enough downloading time can be reserved for the current playing device before the Bluetooth transmission quality is seriously deteriorated, and the current playing device can still receive Bluetooth audio and video data with higher quality sent by the sound source device in the process of switching to complete playing switching.
And when any one of the conditions of the preset playing switching conditions is detected, the current playing equipment downloads the network audio and video data corresponding to the current audio and video.
For example, the current playing device is configured with a WIFI module, and can connect to a router to access a music server on the internet. Specifically, downloading the network audio and video data corresponding to the current audio and video according to the audio and video information of the current audio and video corresponding to the bluetooth audio and video data sent by the sound source device and received by the current playing device may include:

Specifically, according to the downloading speed of the network audio and video data, the downloading amount of the network audio and video data, namely the size of the downloaded network audio and video data, is calculated, meanwhile, the playing progress of the current audio and video is checked, and the size of the played Bluetooth audio and video data is determined. When the downloaded network audio and video data is determined to be larger than the played Bluetooth audio and video data, the playing progress of the current audio and video is recorded, such as the played time or the played Bluetooth audio and video data, and meanwhile, the network audio and video data is correspondingly positioned, the switching from the Bluetooth audio and video data to the network audio and video data is completed, the process is completed instantly, and the continuous playing of the current audio and video without interruption can be completely realized.
In addition, when the resources of the network audio and video data are determined, the network audio and video data can be immediately positioned and downloaded according to the current audio and video playing progress, the network audio and video data can be directly switched and played without waiting for buffering the network audio and video data, and the time for switching and playing of the current playing equipment is further shortened.
In this embodiment, after the current audio/video is played, the current playing device may query the audio/video information of the next segment of audio/video according to a pre-stored play list of the sound source device, and continue to acquire the network audio/video data from the internet for playing according to the audio/video information of the next segment of audio/video.
The playing control method in the audio/video playing system provided by the embodiment of the invention is characterized in that when a playing device plays audio/video of a sound source device connected with a Bluetooth device, a preset playing switching condition is detected periodically or in real time, and if the preset playing switching condition is detected, network audio/video data corresponding to the current audio/video is downloaded from the internet according to audio/video information (such as a song name, an album and a singer of the current audio/video) of the current audio/video being played by the playing device; and then, stopping receiving the Bluetooth audio and video data sent by the sound source equipment corresponding to the current audio and video, switching into the position corresponding to the network audio and video data from the position where the current audio and video is stopped to play the current audio and video continuously, effectively preventing the current audio and video from being interrupted due to the variation of the Bluetooth signals, and improving the audio and video playing quality of the audio and video playing system.
