HEB20 - HD/SD-SDI digital audio embedder

Description

The HEB20 is a serial digital component video HD SDI(SMPTE-292M) digital audio embedder. It is capable of inserting or appending 4 free-running AES/EBU digital audio channels (8 channels). The core of the HEB20 consists of four embedder-blocks Emb_A, Emb_B and Emb_C and Emb_D. Each block is capable of embedding 4 audio channels into one group, which gives a total of 16 audio channels into four groups. In addition, four ADD-ON cards can be connected to create a routing matrix. Two ADD-ON cards are needed to get 16 embedded channels. The architecture of Emb_A to Emb_B blocks are identical. The local inputs have the opportunity to do additional Phase and Gain corrections (on the fly). The HEB20 has two HD-SDI processed outputs.
