The operation message comprises an operation type, a message identification and operation content. The operation types may include deletion, addition, or sequential adjustment, etc.
The Message identifier is an identifier that uniquely identifies the Message, and the Message identifier may be a Hash value based on the current time, for example, a Message Digest Algorithm (MD 5) value or a Secure Hash Algorithm (Secure Hash Algorithm, SHA1) value based on the current time. It should be noted that the message identifier may also be other information that can uniquely identify the message, which is not limited in this embodiment.
The operation content is specific operation content of the playlist included in the message, and may include, for example, a MAC address of a terminal that generates the message, a MAC address of a playback device that receives the message, or song information to be deleted.
And 102, receiving a second operation message of other terminals to the playlist broadcasted in the audio and video playing system.
