摘要： A hardware-implemented video broadcasting receiver is described that is capable handling back-to-back and parallel time slices in an efficient manner, thereby providing improved receiver performance. In one implementation, the hardware-implemented video broadcasting receiver is capable of handling back-to-back time slices of up to 2 Megabits (Mbits) each and, depending upon the MPE-FEC frame size associated with each time slice, up to 8 parallel time slices or up to 4 parallel time slices transmitted back-to-back with 4 other parallel time slices. The hardware-implemented video broadcasting receiver advantageously permits more efficient and flexible use of the available spectrum and increases interoperability with other DVB-H compliant equipment.

摘要： A hardware-implemented video broadcasting receiver is described. The hardware-implemented video broadcasting receiver includes a radio frequency (RF) tuner, a demodulator connected to the RF tuner, link layer logic connected to the demodulator, and a power manager connected to the RF tuner, the demodulator and the link layer logic. The power manager is configured to receive delta-T values extracted from a transport stream by the link layer logic, to determine whether each of the RF tuner, the demodulator and the link layer logic can be powered down based on the delta-T values, and to power down the RF tuner, the demodulator and the link layer logic based on the determination, thereby reducing the average power consumed by the video broadcasting receiver.
