Signal compensation device and associated method

A method for signal dynamic compensation, comprising:

• receiving a first video signal from a first video source;
• receiving a second video signal from a second video source that is different from the first video source, wherein both the first video signal and the second video signal correspond to a same program;
• storing a first transport stream (TS) packet group corresponding to the first video signal to a first buffer;
• storing a second TS packet group corresponding to the second video signal to a second buffer;
• and
• dynamically storing a first TS packet of the first TS packet group or a second TS packet of the second TS packet group to a third buffer according to a predetermined source in response to TS packet status, wherein the predetermined source is one of the first video source and the second video source;
• wherein the first TS packet corresponds to the second TS packet, and the step of dynamically storing the first TS packet of the first TS packet group or the second TS packet of the second TS packet group to the third buffer according to the predetermined source in response to TS packet status comprises:
• in response to both the first TS packet and the second TS packet being damaged, searching for a third TS packet from a server according to a content of an adaptation field in a header of the first TS packet or the second TS packet;
• and
• in response to the third TS packet being searched from the server, downloading the third TS packet from the server for storing to the second buffer or the third buffer.
