摘要： A set-top box for changing channels and method for use of the same are disclosed. In one embodiment, the set-top box includes a network interface controller that is configured to receive a source internet protocol television signal, which includes two channels, from an external source and at least partially prepare the source internet protocol signal in order to forward the tuned signal to a television. The set-top box saves in a buffer the at least partially prepared second channel beginning at a recent periodic, sequential signal access point. In response to receiving a channel change instruction when the set-top box is forwarding the at least partially prepared first channel signal, the set-top box causes the television tuner to forward the at least partially prepared signal based on the second channel stored in the buffer beginning at the recent periodic, sequential signal access point.

摘要： A blind scan method includes setting a tuner to scan a first spectrum block with a first center frequency as a center and determining whether the first spectrum block comprises a possible signal; adjusting the tuner to scan a second spectrum block with a second center frequency as the center according to a first rise point and a first drop point when it is determined that the first spectrum block comprises the possible signal; and determining whether the second spectrum block comprises a valid signal.

摘要： In one example, a remote tuner module includes: a first tuner to receive, process and demodulate a first radio frequency (RF) signal to output an analog audio signal, and to receive and process a second RF signal to output a first downconverted modulated signal; a second tuner to receive and process the second RF signal to output a second downconverted modulated signal; a demodulator circuit coupled to the first and second tuners to demodulate and link the first and second modulated signals, to output a linked demodulated signal. The remote tuner module may further include a gateway circuit coupled to at least the demodulator circuit to output the analog audio signal and the linked demodulated signal.

摘要： Two-tuner media device systems and methods are operable to pre-tune a second tuner in anticipation of a channel surfing activity. An exemplary embodiment receives a first content stream associated with a currently presented channel at a first tuner, determines an anticipated channel based upon the currently presented channel and a historical channel surfing pattern, receives a second content stream associated with the anticipated channel at a second tuner, detects an initiation of a channel surfing activity, and presents at least a video portion of the second content stream associated with the anticipated channel in response to detecting the initiation of the channel surfing activity.

摘要： A terminal apparatus having a function of remotely controlling a video display apparatus includes a communication unit that transmits a command related to setting of the video display apparatus and receives status information, a signal receiving unit that receives a signal output from a broadcast station and decodes a video content, a memory unit that stores a content of a command including a channel of the video content, and a display unit that displays the video content and various types of information. In this terminal apparatus, the communication unit transmits an identification code specific to the terminal apparatus when transmitting the command, and when the status information is received after a channel of the video display apparatus is set by remote control, the video content of the channel stored in the memory unit is decoded by the signal receiving unit and is displayed on the display unit.
