摘要： A content access device includes an interface module that receives a transport stream and outputs a processed transport stream. An input buffer buffers the received transport stream. A polling processor processes the transport stream based on the at least one key to generate the processed transport stream, wherein the polling processor operates to descramble individual packets of the transport stream in a plurality of polling slots of a polling loop. An output buffer buffers the processed transport stream for output by the interface module.

摘要： A universal serial bus (USB) dongle device includes a USB interface for receiving a video signal in a first format and for sending a processed video signal in a second format wherein the first format differs from the second format. An encoding module generates the processed video signal based on the video signal. In a further embodiment, A video card includes a video receiver for receiving a video signal in a first format, based on a selection command. An encoding module generates a processed video signal in a second format based on the video signal, wherein the first format differs from the second format. A USB interface transfers the processed video signal to the host device, receives the selection command from the host device and receives a power signal from the host device to power the video receiver and the encoding module.
