Extended Signaling Methods for Reduced Video Decoder Power Consumption Using Green Metadata
In this paper, we discuss one aspect of the latest MPEG standard edition on
energy-efficient media consumption, also known as Green Metadata (ISO/IEC
232001-11), which is the interactive signaling for remote decoder-power
reduction for peer-to-peer video conferencing. In this scenario, the receiver
of a video, e.g., a battery-driven portable device, can send a dedicated
request to the sender which asks for a video bitstream representation that is
less complex to decode and process. Consequently, the receiver saves energy and
extends operating times. We provide an overview on latest studies from the
literature dealing with energy-saving aspects, which motivate the extension of
the legacy Green Metadata standard. Furthermore, we explain the newly
introduced syntax elements and verify their effectiveness by performing
dedicated experiments. We show that the integration of these syntax elements
can lead to dynamic energy savings of up to 90% for software video decoding and
80% for hardware video decoding, respectively.Comment: 5 pages, 2 figure
