Claims
- 1. Broadcast signal channel selecting apparatus, comprising:
- means for receiving a plurality of broadcast signals;
- means for assigning a respective priority to each of said plurality of broadcast signals in accordance with a respective amount of previous selection time of said each broadcast signal;
- selection means operable to select one of said plurality of broadcast signals in accordance with the priorities assigned to the received broadcast signals; and
- tuning means tunable to the selected broadcast signal for supplying said selected broadcast signal as an output,
- said selection means being operable in both an up mode and a down mode to select other one of said broadcast signals having an assigned priority immediately lower in the down mode and immediately higher in the up mode than the assigned priority of the broadcast signal to which said tuning means presently is tuned.
- 2. The apparatus of claim 1, wherein said means for assigning is operable to assign a highest priority to the one of said broadcast signals whose previous selection time is greatest.
- 3. The apparatus of claim 1, wherein said selection means is operable to initially select the one of said broadcast signals having the highest assigned priority when said broadcast signal channel selecting apparatus is turned on.
- 4. The apparatus of claim 1, wherein said selection means is operable to automatically select the one of said broadcast signals having the highest assigned priority.
- 5. The apparatus of claim 1, wherein said means for assigning includes detection means for detecting at predetermined time intervals the one of said broadcast signals to which said tuning means is tuned, and priority assigning means for assigning a respective priority to each of said broadcast signals as a function of the number of times said each broadcast signal is detected as said one broadcast signal to which said tuning means is tuned.
- 6. The apparatus of claim 5, wherein said priority assigning means is operable to assign a highest priority to the one of said broadcast signals that is detected the greatest number of times.
- 7. The apparatus of claim 1, wherein said broadcast signals include video and audio signals, and the output from said tuning means includes a video signal and an audio signal.
- 8. The apparatus of claim 1, wherein
- said means for assigning includes means for determining days of the week and time periods in each day, and means for assigning respective priorities to each of said broadcast signals for each time period in each day as a function of said respective amount of previous selection time of the respective broadcast signal during said time period,
- said selection means is operable to select one of said broadcast signals in accordance with the priority assigned to each of said broadcast signals for a current time period of a current day, and
- said tuning means is controlled to be tuned to the broadcast signal selected for said current time period.
- 9. The apparatus of claim 8, wherein said means for assigning assigns the highest priority for each time period to one of said broadcast signals whose selection time is greatest for that time period.
- 10. The apparatus of claim 8, wherein said selection means is further operable to automatically select the one of said broadcast signals having the highest assigned priority for said current time period.
- 11. The apparatus of claim 10, wherein said selection means automatically selects the one of said broadcast signals having the highest assigned priority only at a beginning of said current time period.
- 12. The apparatus of claim 8, wherein said means for assigning includes detection means for detecting at predetermined time intervals during said current time period the one of said broadcast signals to which said tuning means is tuned, and means for assigning a respective priority to each of said broadcast signals as a function of the number of times said each of said broadcast signals is detected as said one of said broadcast signals to which said tuning means is tuned during said current time period.
- 13. The apparatus of claim 12, wherein the means for assigning is operable to assign a highest priority for each time period to the one of said broadcast signals that is detected the greatest number of times during that time period.
- 14. Broadcast signal channel selecting apparatus, comprising:
- means for receiving a plurality of broadcast signals;
- tuning means tunable to one of said broadcast signals;
- means for determining days of the week and time periods in each day;
- means for assigning respective priorities to each of said broadcast signals for each time period in each day as a function of a respective amount of previous selection time of said each of said broadcast signals during said time period; and
- selection means operable in both an up mode and a down mode to select one of said broadcast signals having an assigned priority for a current time period of a current day immediately lower in the down mode and immediately higher in the up mode than the assigned priority of one of said broadcast signals to which said tuning means presently is tuned;
- said tuning means being operable to tune to said one of said broadcast signals selected by said selection means.
- 15. The apparatus of claim 14, wherein said means for assigning includes detection means for detecting at predetermined time intervals during said current time period one of said broadcast signals to which said tuning means is tuned, and means for assigning a respective priority to each of said broadcast signals as a function of the number of times said each of said broadcast signals is detected as said one of said broadcast signals to which said tuning means is tuned during said current time period.
- 16. The apparatus of claim 15, wherein the means for assigning is operable to assign a highest priority for each time period to the one of said broadcast signals that is detected the greatest number of times during that time period.
- 17. The apparatus of claim 14, wherein said broadcast signals include video and audio signals, and the output from said tuning means includes a video signal and an audio signal.
- 18. The apparatus of claim 1, wherein said means for assigning further identifies each of said broadcast signals as a high priority broadcast signal or a low priority broadcast signal; and said selection means is operable to select one of said high priority broadcast signals having a carrier frequency higher than a carrier frequency of said broadcast signal to which said tuning means is tuned, and is further operable to select one of said high priority broadcast signals having a carrier frequency lower than the carrier frequency of said broadcast signal to which said tuning means is tuned.
