Abstract: A projection apparatus capable of being built into an inflatable product is provided and includes an inflatable cloth sleeve. A projection device and an audio playback device are fixedly connected inside the inflatable cloth sleeve, an imaging space is arranged between a front end of the projection device and the inflatable cloth sleeve, and the projection device and the audio playback device are wirelessly connected with an intelligent terminal. By combining the projection device with the inflatable cloth sleeve, the projection device has a larger imaging distance and a wider imaging range, and video pictures are dynamically displayed on the surface of the inflatable cloth sleeve, thus improving the display effect of the inflatable cloth sleeve. The projection device has a variety of installation and connection methods, which can meet different installation requirements, and can also play recordings or audio through the audio playback device, further improving interactive effect.

Abstract: A broadcast system for media content sharing includes a receiver, a verification module, a communication module, a storage, a processor and a transmitter. The receiver receives a configuration information of a media program from a first client. The verification module verifies the configuration information of the media program. The communication module communicates with a second client to confirm a transmission time period when the verification performed by the verification module is passed. The processor transforms the media program as a data stream and stores the data stream in the storage. The transmitter transmits the data stream to the second client.
