Enhanced cablecard processor including OOB simulator

摘要

An enhanced cable card device is described that operates in host devices without requiring an out-of-band data channel. One embodiment includes a broadcast receiver for receiving a broadcast signal, a processor for coordinating processing in the cable card, a memory for storing data normally received by the cable card over an out-of-band signal, an in band data receiver for receiving an in band data signal, and a control program running on the processor to signal reception of an out-of-band signal to a host device electrically connected to the cable card. In addition, the control program processes data from the memory and provides processed output data to the host device simulating data normally received over an out-of-band data channel, and the cable card allows the host device to operate normally without an out-of-band receiver.

主权项

1. A cable card, comprising:
an in-band processor configured to receive an in-band signal extracted from a broadcast signal by a host device, where the in-band processor is configured to coordinate processing in the cable card and the broadcast signal further comprises an out-of-band signal that is not received by the in-band processor; a memory configured to store out-of-band spoofing data utilized by a control program to spoof a host device to interface with the cable card as if the cable card is processing data received from the out-of-band signal; wherein the control program configures the processor to:
send a signal indicative of reception of an out-of-band signal to a host device electrically connected to the cable card despite not receiving the out-of-band signal; andprocess the out-of-band spoofing data from the memory and provide processed output data to a host device simulating data received from an out-of-band signal.
