ISDB-T Encoder Modulator VCAN1474

ISDB-T Encoder Modulator

ISDB-T Encoder Modulator

General Description

The encoder & modulator is designed based on consumer electronics which allow audio/video signal input in TV distributions with applications in home entertainment, surveillance control, hotel Digital Signage, shops, nezvimwewo.
It is an all-in-one device integrating MPEG-4 AVC/H.264 encoding and modulating to convert audio/video signals into ISDBT/DVB-T RF out.
The signal source could be from STB, satellite receiver, closed-circuit television cameras, and antenna, nezvimwewo. Its output signal is to be received by ISDBT/DVB-T TV sets or STBs etc.
