LOW POWER DOWNLOAD OF SOFTWARE APPLICATIONS FOR DIGITAL HYBRID TV

摘要

Energy consumption is reduced in a hybrid analog-digital television receiver (100) by providing an active standby mode where the television display (170) is depowered, but the digital part (110) remains powered to search transport streams in the digital broadcast signal for software or a download schedule indicating a date and time to download the software. Once the digital part recovers the necessary information, it reports back to the analog part (130), and the analog part depowers the digital part to achieve a normal standby mode. A time for downloading the software may also be reported to the analog part. The analog part includes a timer (160) for waking up the digital part to cause it to enter the active standby mode to download the software at the indicated time. An interface (120) enables communication between the digital and analog parts.
