Abstract

The invention provides wireless broadcast transmitting and receiving equipment and a communication system. The wireless broadcast transmitting equipment and the wireless broadcast receiving equipmentcommunicate in a time period of a broadcast interval and a control interval, wherein a second time period in the broadcast interval is used for transmitting to-be-broadcasted data broadcasted by the wireless broadcast transmitting equipment, a first time period in the control interval is used for transmitting a control sequence sent by the wireless broadcast transmitting equipment, and a second time period in the control interval is used for transmitting feedback information sent by the wireless broadcast receiving equipment. Due to the fact that an information feedback channel and an information feedback mechanism are established in the wireless broadcast communication system, a broadcast receiving end can inform a broadcast transmitting end of local state information and control information of the broadcast receiving end, and the broadcast transmitting end can know the information in time.

Description

technical field

[0001] The present application relates to the technical field of wireless broadcasting, in particular to a wireless broadcasting transmitting and receiving device and a communication system. Background technique

[0002] The rapid development of radio frequency wireless connection technologies such as Bluetooth and WiFi have made wireless audio sharing a part of people's lives. For example, WiFi smart speakers centered on routers, and Bluetooth smart speakers or smart headphones centered on smartphones bring great convenience for people to share audio. In particular, point-to-multipoint wireless broadcasting enables the sharing of audio in multiple rooms. For example, the point-to-multipoint wireless audio broadcasting function realized by adopting classic Bluetooth's connectionless slave broadcast (CSB: Connectionless SlaveBroadcast) technology and low-power Bluetooth broadcast synchronous stream (BIS: Broadcast Isochronous Stream) technology.
