ABSTRACT:
A testing jig is comprised of a circuit board which replaces and emulates the data transfer between a network interface module and a decoder engine of a settop box in a digital network. The testing jig receives the encoded video output of an encoder used in the network and converts the protocol of the encoded video directly into the protocol used for data transfer between the network interface module and the decoder engine, thus bypassing all of the elements in the network between the encoder and the settop box and facilitating the testing of the video output by an encoder or the decoding performed by a decoder engine of a settop box.
