The GEB950 is a 3GB/s SDI, HD SDI and SD SDI audio embedder. It is capable of inserting or appending free-running AES/EBU digital audio channels or analog audio channels. The card has 2 option input boards: 4 mono analog audio inputs (4ch total) per board, or 4 stereo AES/EBU inputs (8ch total) per board.
The core of these modules consists of four embedder-blocks Emb_A, Emb_B, Emb_C and Emb_D and 2 delay blocks. These blocks can be used in series for a single SDI 4 group embedder with up to 1 sec of video offset delay, or in parallel for 2 individual channels with each 2 group embedders and individual 500ms offset delay in a fully separate (clock lock*) channel TWINS function. Each block is capable of embedding 4 audio channels into one group, which gives a total of 16 audio channels into four (or 2x2) groups. The TWINS mode is a single command operation and controls 4 individual selection switches as can be seen in the block diagram.
In addition, four ADD-ON cards can be connected to create a routing matrix. The architecture of Emb_A to Emb_D blocks is identical. The local AES inputs can be controlled to adjust Phase, Gain and delay (on the fly).
