12 CCTV (ADV212, ADA4851-1, AD8131, AD8130, AD8113, ADSP-BF548)

14 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)?

15 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.

16 ADV212 Features Compliance to the JPEG2000 standard for still and motion pictures. SURF (Spatial Ultra-efficient Recursive Filtering) technology No external memory needed – competitive solutions need frame buffer memory Lower power – ~500mW of power dissipation Low Latency - <1.5 frames for encode or decode; 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 4:2:2 mode; 4096 pixels in single-component mode. Various standard video and microcontroller (16/32-bit) Interfaces for ease of use Flexible pixel interface supporting 8, 10, 12, 14, 16-bit Y, Cr, Cb pixels Compact 12x12 or 13 x 13 BGA package

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 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
