A method for determining signal reception quality at a terminal, said method comprising: receiving a digital broadcast signal; detecting a first bit error rate, first BER, of said digital broadcast signal; detecting a second bit error rate, second BER, of said digital broadcast signal after said digital broadcast signal is decoded by a first decoder (152, 250); detecting packet error rate, PER, of said digital broadcast signal after said digital broadcast signal Z decoded by said first decoder is further decoded by a second decoder (154, 270); and determining (S32, 533, S34) reception quality of said digital broadcast signal based upon a value of said first BER, said second BER, and said PER, characterized in that said first bit error rate is detected before said digital broadcast signal is decoded by the first decoder (152, 250), and said determining reception quality comprises: comparing said packet error rate with a first threshold value (Th_C), wherein if said PER exceeds said first threshold value (Th_C), then said reception quality is defined as a first quality level, otherwise said determining reception quality further comprises: comparing said second bit error rate with a second threshold value (Th_A) after comparing said packet error rate with said first threshold value (Th_C), wherein if said second BER exceeds said second threshold value (Th_A), then said reception quality is defined as a second quality level, otherwise, said determining reception quality further comprises: comparing said first bit error rate with a third threshold value (Th_B1) after comparing said second bit error rate with said second threshold value (Th_A), wherein if said first BER exceeds said third threshold value (Th_B1), then said reception quality is defined as a third quality level. receiving a digital broadcast signal; detecting a first bit error rate, first BER, of said digital broadcast signal; detecting a second bit error rate, second BER, of said digital broadcast signal after said digital broadcast signal is decoded by a first decoder (152, 250); detecting packet error rate, PER, of said digital broadcast signal after said digital broadcast signal Z decoded by said first decoder is further decoded by a second decoder (154, 270); and determining (S32, 533, S34) reception quality of said digital broadcast signal based upon a value of said first BER, said second BER, and said PER, characterized in that said first bit error rate is detected before said digital broadcast signal is decoded by the first decoder (152, 250), and said determining reception quality comprises: comparing said packet error rate with a first threshold value (Th_C), comparing said packet error rate with a first threshold value (Th_C), wherein if said PER exceeds said first threshold value (Th_C), then said reception quality is defined as a first quality level, otherwise said determining reception quality further comprises: comparing said second bit error rate with a second threshold value (Th_A) after comparing said packet error rate with said first threshold value (Th_C), wherein if said second BER exceeds said second threshold value (Th_A), then said reception quality is defined as a second quality level, otherwise, said determining reception quality further comprises: comparing said first bit error rate with a third threshold value (Th_B1) after comparing said second bit error rate with said second threshold value (Th_A), wherein if said first BER exceeds said third threshold value (Th_B1), then said reception quality is defined as a third quality level. comparing said second bit error rate with a second threshold value (Th_A) after comparing said packet error rate with said first threshold value (Th_C), wherein if said second BER exceeds said second threshold value (Th_A), then said reception quality is defined as a second quality level, otherwise, said determining reception quality further comprises: comparing said first bit error rate with a third threshold value (Th_B1) after comparing said second bit error rate with said second threshold value (Th_A), wherein if said first BER exceeds said third threshold value (Th_B1), then said reception quality is defined as a third quality level. comparing said first bit error rate with a third threshold value (Th_B1) after comparing said second bit error rate with said second threshold value (Th_A), wherein if said first BER exceeds said third threshold value (Th_B1), then said reception quality is defined as a third quality level.
