AV Conversion to ASI and IPTV HDE 210
Conversion from AV analogue to an MPEG transport stream and IPTV (AV – ASI and IPTV)
The twin encoder cassette HDE 210 converts two analogue video and audio signals into two MPEG2 data streams. These data streams are outputted at the ASI interface or LAN (IPTV) interface.
The analogue video signal can be fed in either the video (yellow) cinch connectors (CVBS) or via the S-Video connectors (Y/C). The stereo audio signals are fed in via the audio (red and white) cinch connectors. PAL BG (4.43 MHz) and PAL N (3.58 MHz) are supported.
The analogue video and audio signals are digitalized and are the input signal for the MPEG2 encoder. An existing teletext signal is digitalized via the MPEG2 encoder and can be used at the output of the ASI transport stream.
The MPEG2 encoder generates a transport stream according to ISO/IEC 13818-2 at an 8-bit wide TS interface with clock and frame sync signal with data rates between 2 MBit/s and 15 Mbit/s. The data rate of the audio channel is between 192 kbit/s and 384 kbit/s and supports the following sound modes: stereo, joint stereo, mono and dual.
The ASI transport stream can be cascaded. This means that the encoded AV data streams are fed in automatically or they can be edited manually.
The transport stream can be outputted alternatively as SPTS (Single Program Transport Stream) resp. MPTS (Multi Program Transport Stream) in UDP (User Data Protocol) format or RTP (Real-Time Data Protocol).
The transport stream (ASI/SPTS/MPTS) contains every necessary service IDs which are necessary for the reception with a DVB receiver unit (e.g. set-top box).
The firmware update of this cassette can be done via the RS-232 interface.
