Chapter 1 Introduction
1.1 Product Overview
B-QAM-SDI-IP-2CH-LL
series products are
QuestTel
‟s new breakthrough all-in-
one devices which integrate encoding (MPEG-2 HD/SD, MPEG-4/AVC H.264 HD/
SD) and modulating to convert V/A signals into DVB-C RF output. It has equipped
with 2 SDI channels input and 1 ASI input and output with 2 ASI ports and 1 UDP IP
port.
Now, the latency problem has been greatly reduced to achieve an extremely low value
from the encoding progress to the decoding terminals.
It adopts inner drawer-type structural design which greatly facilitates the change of
encoding modules (HDMI/SDI /…) as needed.
The signals source could be from satellite receivers, closed-circuit television
cameras, Blue-ray players, and antenna etc. Its output signals are to be received by
DVB-C TVs or STBs and etc.
