Abstract
Receiving packets of digital data includes detecting a packet header of a received packet, determining a calculated check value for the received packet, and comparing the calculated check value with a transmitted check value provided with the packet. The packet may be discarded in response to the calculated check value not being equal to the transmitted check value. The transmitted and calculated check values may be CRC values having two or four bytes. The data may be provided via digitized data superimposed onto a video signal.
