摘要： Various aspects include methods for facilitating digital rights management (DRM) within an electronic device. Various aspect methods may include receiving a first broadcast message, storing a DRM license object extracted from the DRM license-related message, receiving a DRM license request message generated by a content decryption module (CDM) of the electronic device, determining that the DRM license object is associated with the encrypted content received by the electronic device during the broadcast content session based on the identification information included in the DRM license request message received from the CDM of the electronic device, and sending the DRM license object to the CDM of the electronic device. The first broadcast message may be a DRM license-related message generated by a broadcast server. The DRM license request message may include identifier information associated with encrypted content received by the electronic device during a broadcast content session.

摘要： A method is described for defining service metadata for multiple RF channel services with no impact to the currently defined service metadata for single tuner receiving devices. One example may include receiving first service layer metadata from a first communication channel and second service layer metadata from a second communication channel; and determining a plurality of services available from the first and second communication channels based on the first and second service layer metadata, wherein at least one of the plurality of services is a multiple channel service that comprises data in a pooled set of the first and second communication channels, wherein the multiple channel service is identified by matching a first service from the first service layer metadata and a second service from the second service layer metadata to identify the at least one of the plurality of service in the pooled set.

Sets of durations are then provided associated with each such integer multiple sequence of carriers that allow for the combined duration of the symbol duration and extended duration cyclic prefix to result in an integer number of carriers for each RB.
