 Section

 MJPEG

 MPEG-4

 Strong Points

 - Maintains constant quality
    regardless of bandwidth
 - Image quality maintained regardless
    of complexity of image
 - Excellent Compatibility: Used as     standard compression for all PC's
 - Easy to manage, use and store
 - Low-cost encoding/decoding used
 - Quick search and easy to handle
    images
 - Separate image per frame
 - Outstanding Recovery: Fast recovery
    for packet losses
 - Short fetching standby time

 - Maintains high frame rate
    even in high bandwidths
 - High Compression: When requested
    in low bandwidth
 - Small Storage Space
 - Constant bit rate (CBR)
    - Used when making network designs
       and bandwidth equipment simple
 - Variable bit rate(VBR)
    - Used when there are no restrictions
       in bandwidth
    - Ensures high image quality
       according to increasing bit rate

 Weak Points

 - Increased bandwidth through higher
    frame rate
 - Needs large storage space
 - Keeps constant bandwidth even when
    there is no motion

 - Complex Video Compression
 - Long video fetching standby time.
 - Requires PC specs with high
    performance monitoring
 - Heavy loss when there is packet
    losses.
 - Additional license costs for encoding
    and decoding
 - Uses many profiles and levels making
    it difficult to procure a standard.
