Claim:
1. A method for facilitating power management during real time playback of a digital broadcast on a receiver device comprising a communication interface, comprising: associating a stream of media packets of the digital broadcast with system time clock (STC) timestamps indicating when the stream of media packets were received by the receiver device; storing the stream of media packets in a temporary buffer of the receiver device; determining whether a packet burst threshold for the temporary buffer of the receiver device has been reached, wherein the packet burst threshold is one of a time threshold and a size threshold; configuring a conditional access module coupled to the receiver device to operate in a first operational mode other than a first low-power mode in response to determining that the packet burst threshold for the temporary buffer of the receiver device has been reached, wherein the configuring is by a signal sent from the receiver device; and sending, via the communication interface in a second operational mode other than a second low-power mode and while the conditional access device is in the first operational mode, a burst of media packets from the temporary buffer of the receiver device to the conditional access module in response to determining that the packet burst threshold for the temporary buffer of the receiver device has been reached, wherein the communication interface operates in the second low-power mode when not sending bursts of media packets.
