CSE 3300 AV conversion analogue to digital


Conversion from AV analogue to an MPEG transport stream

The twin encoder cassette CCE 200 converts two analogue audio video signals into two elementary transport streams.

The cassette supports the format D1 (720 x 576 pixels) with data rates of 1.5 Mbit/s to 6 Mbit/s. A 16-bit stereo sound channel is already included in this data rate.

The audio encoder works with MPEG1 Layer II. The audio bit rates (256fs, 320fs and 384fs) and the AUDIO ES Modes Stereo, Joint Stereo Dual and Mono are adjustable. The audio input signal of the stereo A/D converter can be adapted to the particular situation with an adjustable amplifier.

The audio sample rate (fs) is 48 kHz.

The transport stream according to ISO/IEC 13818 is at the output via SPI interface with an8-bit TS interface with clock and frame-sync signal.

The HDE 200 cassette can be combined with the quadruple converters HDM 203/204/205 QMX.

Quadruple conversion from an MPEG transport stream to Digital Cable (QAM)

The cassette merges four parallel elementary data streams to one elementary data stream and converts it to a QAM modulated carrier. In this connection it is about a static multiplexing of DVB data streams.

Channels can be deleted from the data stream at data input A. Channels which are fed at the inputs B, C and D can be selected and added from the data streams. The available information in the data stream (e.g. time information TDT, event information EIT) are passed unmodified from input A to the output.
