Claims
- 1. A signal processing circuit for use in a broadcast receiving apparatus for receiving a broadcast signal, the broadcast receiving apparatus including a tuning request storage section, the signal processing circuit comprising:
a tuning request reception section for receiving an issued tuning request; a tuning process section for performing a tuning process for the broadcast signal corresponding to the issued tuning request, wherein, if at least one tuning request is issued during the tuning process, the tuning process section performs a next tuning process corresponding to one of the at least one tuning request stored in the tuning request storage section during the tuning process; and a tuning request erasure section for erasing, at a predetermined point in time, the at least one tuning request stored in the tuning request storage section during the tuning process, wherein the tuning request received by the tuning request reception section is stored to the tuning request storage section.
- 2. The signal processing circuit according to claim 1, wherein the tuning request erasure section erases the at least one tuning request stored in the tuning request storage section at the beginning of the tuning process.
- 3. The signal processing circuit according to claim 1, wherein
if the tuning process fails, the tuning process section performs a further tuning process corresponding to one of the tuning requests stored in the tuning request storage section during a previous tuning process, and the tuning request erasure section erases the at least one tuning request stored in the tuning request storage section during the previous tuning process after the further tuning is completed.
- 4. The signal processing circuit according to claim 1, wherein, if at least one tuning request is issued during the tuning process, the tuning process section performs a next tuning process corresponding to a most recent tuning request among the at least one tuning request stored in the tuning request storage section.
- 5. The signal processing circuit according to claim 1, wherein the tuning requests are issued by a software application.
