A system, method, and computer program product are provided for buffering an audio video (AV) stream, audio/video header information, and an audio/video elementary stream for hardware audio/video digital rights management (DRM) processing. In operation, an AV stream encrypted under a shared symmetric key in an M2TS format is buffered, where the AV stream includes content including at least one of audio or video and all content data associated with the AV stream is removed at picture level and below, with the exception of content headers associated with the content data. Additionally, content header information encrypted under the shared symmetric key is buffered, the content header information indicating locations of the content headers associated with the content data. Further, a content elementary stream encrypted under a hardware secret key is buffered for consumption of a hardware bit stream decoding engine. |
