Patent ID: 8212940

Claim:
A television (TV) receiving system comprising: a converter, included in a dongle attachable to the computing device, receiving a radio frequency (RF) signal and producing data representing an intermediate frequency (IF) signal, wherein the converter includes: a RF tuner configured to receive the RF signal and produce the IF signal; an analog-to-digital converter (ADC), coupled to the RF tuner, receiving the IF signal and producing the data representing the IF signal; an automatic gain controller (AGC) provided to ensure that the IF signal is properly produced by the RF tuner; a port interface to be communicated with a corresponding port interface of the computing device to transmit the data to the computing device; a compression unit provided to compress the data to satisfy a transmission rate determined by a protocol between the port interface and a corresponding port interface of the computing device; and a module being executed in a computing device to receive via a port thereof the data from the converter, the module including a plurality of demodulators, each of the demodulators corresponding to one TV standard, the module configured to activate a corresponding one of the demodulators according to characteristics of the IF signal pertaining to one TV standard and decompress and demodulate the data to produce an audio data stream and a video data stream with the corresponding one of the demodulators.
