Abstract

A wireless network for delivering a media asset includes a plurality of media and communication devices. The media asset further includes a video file and an audio file. One of the devices is a controlling device. The video file is delivered by a projector unit and the audio file is delivered by the devices. The projector unit receives the video file from the controlling device when the unit and the device are connected. The controlling device can remotely control operations of the projector unit.

Claims

1. A wireless network for delivering a media asset including a video file and an audio file to a plurality of users, the network comprising:

a. a plurality of media and communication devices, wherein each of said devices is carried by a user and one of said device is a controlling device;

b. a projector unit for delivering a video file through a micro projector;

c. a wireless network for connecting said devices and said projector unit, wherein said projector unit is connectable to at least the controlling device through a wired connector and media assets can be transferred from said controlling device to said projector unit through said wired connector;

wherein said controlling device and said projector unit are in single piece after said device and said projector unit are connected;

wherein said audio file can be transmitted from said controlling device or said projector unit to said devices through said wireless network; and

wherein said controlling device can be used as a remote control device for controlling operations of delivering the video file through said projector unit and delivering said audio files through said devices connected to the wireless network.

2. The network as recited in claim 1, wherein said network further comprising a means of delivering said video file and delivering said audio file in all connected devices in a synchronized manner.

3. The network as recited in claim 1, wherein a data file including metadata of transferred media assets is established by a processor of said controlling device and is stored in a file storage system or a cache of said controlling device, wherein said data file may be transmitted to the devices connected to the wireless network.

4. The network as recited in claim 1, wherein metadata of at least a portion of said transferred assets may be displayed through a user interface of said controlling device for the controlling user to select, wherein selected metadata may be transmitted to said projector unit to initiate an operation of retrieving and delivering said video file.

5. The network as recited in claim 1, wherein said each of media and communication devices further comprising:

a. a processor pertaining to control operation of the device;

b. a file storage system for storing data files;

c. a communication interface for networking; and

d. a battery for supply power for the operation of the device.

6. The network as recited in claim 1, wherein said projector unit further comprising:

a. a processor pertaining to control operation of said unit;

b. a file storage system for storing data files;

c. a communication interface for networking; and

d. a battery for supply power for the operation of the unit,

wherein said processor, said file storage system and said battery may be used as additional resources for the controlling device when said unit and said controlling device are connected through the wired connector.

7. The network as recited in claim 1, wherein said wireless network conforms to one or a combination of following standards:

a. Wi-Fi;

b. Bluetooth; and

c. ZigBee.
