RESAMPLING FILTERS FOR SCALABLE VIDEO CODING WITH PHASE OFFSET ADJUSTMENT AND SIGNALING OF SAME
Upsampling filters for use in scalable video coding may be selected from a set of filters each with a different phase. In order to accommodate a phase offset introduced from downsampling required to maintain proper luma/chroma color space positions after upsampling, an offset parameter may be used in computing the filter index. Moreover, a different offset may be used for each filter index. These offsets in effect provide a remapping of the filter indices. By remapping the filter indices in this manner the performance of the upsampling process can be improved and errors introduced by rounding or which are caused by the finite precision of the process used to compute the filter indices can be taken into account.

POLICY ENFORCEMENT FOR MULTIPLE DEVICES USING AN AUDIENCE DEFINITION
In one embodiment, a method determines an audience rule to be applied for delivering content. The audience rule specifies an audience that is defined based on a combination of device properties, content properties, and digital rights management (DRM) properties. A device group associated with a group of devices is determined where devices in the device group are associated with content authorization properties, device properties, and digital rights management (DRM) properties. The method then applies the audience rule to the device group to determine any devices in the group of devices in which a content authorization for a device should be altered based on analyzing the content authorization properties, device properties, and digital rights management (DRM) properties of the device group and the combination of device properties, content properties, and digital rights management (DRM) properties of the audience rule.

METHOD FOR PROVIDING MULTICAST DNS SERVICES ACROSS IP SUBNET BOUNDARIES
A network address translation (NAT) gateway intercepts packets and determines whether they contain multicast domain name server (mDNS) query or response messages. Upon receiving an mDNS message, the NAT gateway performs address translation to assign a new source address and stores the original source address in a translation table. The NAT gateway then forwards the message to all adjacent networks in order to expand the reach of the packet. If the mDNS messages establish a new client-server connection, the NAT gateway brokers the connection by either acting as a proxy or continuing to perform network address translation.
