Abstract for group USBMedia

The project idea stems from the need of a device to enable the use of
personal computers as multimedia entertainment center in a convenient
way and incorporate the use of traditional video equipment that
outputs analog NTSC signals.

The device consists of 2 functional parts. 

1) NTSC signals converter

It takes NTSC signal input from the Xilinx S-video port, decode them
into digital formats (e.g. MPEG, wav) using the Microblaze processor
and output it through the USB port to the computer. The user will be
able to view it from the screen with a custom-made video-viewing
software.
  
2) Remote Control

The remote control is a separate unit that transmits RF signals to the
Xilinx Board. Analog signals will be transmitted and circuitry in the
receiver will digitize the signals and send to the FPGA. Upon
receiving a signal, the FPGA will send the appropriate instructions
through the USB port to the USB host, a personal computer.

Functions of the remote control: 

Video:
1.Start viewing the NTSC signal on the screen. 
2.Stop viewing the NTSC signal on the screen

Audio:
The plan is to use existing music software with APIs (e.g. Winamp). A
program will be built within the USB driver to send commands to
control the software. 
Start Audio program.

Others: 
The USB driver will also send command to control the volume the default soundcard of Windows. 
3.VolumeUp 
4.VolumeDown 

Due to the complexity of the project, our group consists of six group members.
