Video quality

Bosch uses best of breed compression Motion video compression, not still image “Compression agnostic” – best quality/cost trade off

1. Constrained connections – GSM, ISDN, ADSL Medium resolution MPEG4, scaleable frame rate

CIF at a few seconds per frame over GSM 9.6Kbps CIF at 7-10fps over ISDN 100Kbps CIF at 15-25fps over ADSL 200Kbps

2. Typical LAN Medium to full resolution, full-frame rate

CIF at 25ips MPEG4 at 700Kbps average 2CIF at 25ips MPEG4 at 1250Kbps average 4CIF at 25ips MPEG4 at 2.5Mbps average

3. Ultimate quality DVD quality

4CIF at 25ips MPEG2 at 3.5Mbps to 5Mbps

IP Network Video

MPEG4 more efficient than JPEG 6x frame rate of JPEG for same bitrate

4CIF is as good as analog Indistinguishable from analog

Minimal delay MPEG4 under 110ms MPEG2 Low Delay under 180ms Very important for PTZs and domes

Video quality - continued

IP Network Video systems using MPEG-4 deliver higher-quality video than M-JPEG for the same amount of bandwidth.
