Abstract: The disclosure discloses a playing control method and apparatus for a device group, and a playing system. The method of the disclosure includes that: a master device and one or more slave devices are determined from multiple playing devices, the multiple playing devices form a device group, a network connection is established between the master device and a server side; an intra-group connection relationship is established between the master device and the one or more slave devices; in response to acquisition of user data, the one or more slave devices transmit the user data to the master device based on the intra-group connection relationship, and the master device interacts with the server side based on the user data.

Abstract: Disclosed are methods for equipment networking, and equipment. Equipment acquires at least one of first information indicating a state of the equipment or second information indicating a state of peer equipment. The equipment determines whether a pre-set condition is met by at least one of the first information or the second information. When the pre-set condition is met by at least one of the first information or the second information, the equipment forms a group with the peer equipment. The equipment monitors data characterizing a signal transmitted by the peer equipment. When a first pre-set condition is not met by the data characterizing the signal transmitted by the peer equipment, the equipment quits the group formed with the peer equipment.

When the pre-set condition is met by at least one of the first information or the second information, the equipment forms a group with the peer equipment.

Abstract: Provided is a User Datagram Protocol (UDP)-based control command transmission method, in which a sender sends a control command packet to a receiver based on a UDP; and the receiver sends an Acknowledgement (ACK) packet to the sender based on the UDP after receiving the control command packet. A sender and a receiver are also provided.

Abstract: The present disclosure discloses a playing method and a playing device. The playing method for a multiroom sound system includes that: a control channel between a master sound box and a slave sound box is established, wherein the control channel is independent of an audio stream channel or has a priority higher than that of the audio stream channel; during audio playing, when a command configured to pause playing operation is received, the command configured to pause the playing operation is notified to the slave sound box through the control channel; and when the command configured to pause the playing operation is received, data acquisition from a first buffer is stopped to pause the playing operation, wherein the first buffer is an audio buffer of the master sound box.
