SYSTEM DESIGN

• Design of interfaces Well defined, generic set
  of APIs
• Video Library Interface
• Display Interface
• Memory Management Interface
• RTP/RTSP Interface
• An example interface for Video Codec
• vc_alloc(), vc_init(), vc_encode(), vc_decode(),
  vc_free()

IMPLEMENTATION

• Platforms/Tools Linux, C
• Project Phases
• P1 RTP Packetizer, Memory Manager AR
• P2 H.261 library and interfacing SS
• P3 Test suite creation AR, SS
• P4 Display on Linux AR
• P5 Video capture on Linux SS
• P6 System integration AR, SS

9
TESTING

• Unit Testing
• To uncover bugs in the functionality
• Test suites with known input/output
• Integration Testing
• To uncover bugs in the interfaces
• Run COVIT as a client/server/both (in tandem with
  VLC)
• System Testing
• To uncover bugs at the system level
• Plugging into sipc and/or pjsip
