ADV212 in CCTV Applications (FAQ)

• Why consider JPEG2000 when there is MPEG2/4 or
  H.264?
• More flexibility - encode at the highest quality
  (for detailed viewing) but only send portions
  that fit lower transmission bandwidth,
  resolution, frame rate, etc.
• To address HDD space concerns, the customer can
  reduce bit rate during scenes with no motion and
  increase quality when motion is detected
• Low latency - useful in remotely operating a
  camera
• Multiplexing multiple cameras - not possible with
  MPEG
• Regions of motion can be enhanced - not possible
  with MPEG
• Higher image quality - MPEG is not conducive
  toward this trend since it is 8-bits only and no
  still image capability
• Legal Issues Some countries (Australia) do not
  allow MPEG still images as legal evidence (JPEG,
  on the other hand, has been used in the UK
  courts)
• What about JPEG2000 software decoders (for PC
  viewing)?

When would MPEG2/4 be better than JPEG2000?

• MPEG2/4 is better with CCTV applications that
  have the following characteristics
• Streaming only (one-way transmission)
• Bandwidth and storage space are the only concerns
• Mediocre image quality is okay
• Not a lot of movement in images
• In short a Digital VHS type of application
• If the customer wants to do anything beyond
  Digital VHS, they should consider JPEG2000.
  For instance
• Court accepted still images
• High quality still images
• Resolution, quality, and frame-rate scalability
• Conclusion There are surveillance application
  that should use MPEG2/4 other surveillance
  applications would be better off with JPEG2000.

  motion pictures.

  MPEG solutions have up to 10 frames worth of
  latency
• Internal rate control is accurate to /-5
• MPEG or JPEG solutions are content dependent
• Tile/image sizes with widths up to 2048 pixels in
  3-component 422 mode 4096 pixels in
  single-component mode.

  (16/32-bit) Interfaces for ease of use
• Flexible pixel interface supporting 8, 10, 12,
  14, 16-bit Y, Cr, Cb pixels

17
JPEG2000 Competition

• TI offers various MPEG2/4 solutions for
  surveillance using TMS320DM642 however, each
  image is scaled to CIF and then compressed which
  degrades image quality
• Other MPEG vendors Equator, LSI, Korean /
  Taiwanese vendors
• ADI offers their own DSP reference design
  contact local ADI sales for more details
• Current DSPs (TI, etc.) are incapable of
  real-time video encoding / decoding of JPEG2000
• JPEG2000 Competition
• Ricoh - D1 (720 x 480 _at_ 30frames/second)
  capable, but in a 420-ball, 35mm x 35mm package
  and also requires external memory.
• Sanyo in-house JPEG2000 solution
• Sony - will use Sanyo OEM
• IP Vendors Adelante, InSilicon, Amphion, others
