Device and method for generating feedback signal

A method for generating feedback signals in a device, comprising steps of:

• receiving user input, and setting resolution of the device and media types of the television signals according to the user input;
• tuning to a channel according to the user input to receive channel signals;
• decoding the channel signals;
• counting a period;
• detecting whether the device receives television signals;
• detecting whether an interrupt instruction is received if the device does not receive the television signals;
• and
• generating a feedback signal according to the interrupt instruction, and transmitting the feedback signal to a media server if the interrupt instruction is received.

A method for generating feedback signal in a device, comprising steps of:

• tuning to a channel in a device to retrieve channel signals through said channel from a media server data-communicable with said device;
• decoding said retrieved channel signals;
• starting to count a time period in said device;
• detecting whether said device retrieves television signals out of said decoded channel signals through said channel;
• generating a feedback signal in said device when no television signal is retrieved in said device and said time period expires;
• and
• transmitting said feedback signal from said device to said media server.
