Caro Miguel Freitas,

A placa de aquisi��o de imagem que utilizas n�o possui as 16 entradas de v�deo 
directas. � feita a multiplexagem das c�maras atrav�s de um IC espec�fico. S� depois 
de concretizada a multiplexagem, � que o sinal � transferido para o bt848.

Como o bttv apenas se encarrega da gest�o do bt848, e n�o possuis nenhum software que 
actue o multiplexer, ent�o nenhuma imagem � colocada na placa de v�deo.

Gostaria de saber mais acerca dessa tua placa, uma vez que estou a desenvolver um 
sistema de v�deo vigil�ncia.

No meu caso optei por desenvolver a placa de aquisi��o. Talv�s devas fazer o mesmo.

Um Abra�o,
Duarte Duque
