Latencyadjusts encoder latency. Affected by video
rate, frame size and rate, and GOP structure.LONG: latency measures close to 1 second
NORMAL: latency is approximately 1/2
second. Best option for standard
transmission and contribution.
LOW: latency approximately three (3) frames
less than the NORMAL setting.
VERYLOW: latency approximately five (5)
frames less than the NORMAL setting.*.ECMD ELANote: the Adtec mediaHubHD 422 encoder function does not support MPEG1 Layer 3 or MP3.Latency Notes:When encoding PAL video with VERYLOW latency, we recommend using IP GOP Structure if the decoder is TT
1260. Otherwise, the TT 1260 will underflow video.• Long IBBP GOPs will produce higher latency over short IP GOPs.• Short IP GOPs at lower bit rates produce lower quality video.• www.adtecdigital.com Pages: 1 … 16 17 18 19 20 … 104 wrong Brand wrong Model non readable See also other documents in the category Adtec digital Video: DPI-1200 (version 01.04.08U) Quick Start (2 pages) DPI-1200 (version 01.04.08U) Manual (58 pages) mediaHUB-HD 422 (version 1.01.10_M_2) Quick Start (2 pages) mediaHUB-HD 422 (version 1.01.10_M_2) Quick Start (67 pages) mediaHUB-HD 422 (version 1.01.10_M_2) Quick Start (68 pages) mediaHUB-HD 422 (version 1.01.10_M_2) Quick Start (2 pages) mediaHUB-HD 422 (version 1.01.10_M_2) Quick Start (2 pages) EN-80 (version 2.02.28) Quick Start (2 pages) EN-30 (version 1.02.02) Manual (59 pages) RD-30 (version 2.1.1) Quick Start (1 page) RD-30 (version 2.1.1) Manual (39 pages) mediaHUB-HD 422 (version 1.01.10_M_2) Quick Start (2 pages) mediaHUB-HD 422 (version 1.01.10_M_2) Quick Start (2 pages) mediaHUB-HD 422 (version 1.01.10_M_2) Quick Start (2 pages) YUV2QAM (version 01.02.01) Manual (46 pages) Soloist-HD Pro (version 02.07.09) Manual (77 pages) EN-91 / EN-91P (version 1.02.29) Quick Start (2 pages) DTA-3050 (version 6.02.14) Manual (94 pages) EN-20 (version 2.03.06) Manual (63 pages) mediaHUB-HD Pro (version 03.07.19) Studio Encoder Quick Start (2 pages) RD-60 (version 1.13.02) Quick Start (2 pages) edje-5110 (version 01.02.05) Manual (98 pages) eyeMonitor (42 pages) TBGS w/adManage (50 pages) Soloist 4111 (version 02.07.03) (1 page) EN-40 (version 2.02.24) (2 pages) mediaHUB (version 02.00.13) (24 pages) edje-5110 (version 01.02.05) Quick Start (2 pages) MAS & iptvManage (44 pages) AVS2 (5 pages) Sitemap

Latency Notes:
When encoding PAL video with VERYLOW latency, we recommend using IP GOP Structure if the decoder is TT
1260. Otherwise, the TT 1260 will underflow video. •
Long IBBP GOPs will produce higher latency over short IP GOPs. •
Short IP GOPs at lower bit rates produce lower quality video. •
