As previously stated, a DMR device must provide device description document metadata that indicates whether the device supports WoL. In addition to this requirement, if a DMR device implements one or more low-power modes of operation, the DMR device must support WoL (NETMEDIA-0076).
Although DMR devices are not required to support WoL, we recommend that device manufacturers be proactive and implement WoL in all devices.
Windows 7 allows devices to modify the user’s ratings for a media item and to update the information on the server. If a DMR device allows editing the microsoft:userRatingInStars metadata attribute, then the DMR device must be able to notify digital media servers of the updated metadata by calling the UpdateObject method that the ContentDirectory service implements. The DMR device must call UpdateObject within 0.5 second of receiving approval of the change from the consumer.
