BCM70015 enables support for H.264/AVC, DivX, MPEG-2/4 and VC-1 video compression for image intensive applications requiring support for 1080p high definition multimedia content.BCM70015 can be put in Apple TV 1 to be used with Crystalbuntu. The BCM70015(marked as BCM970015 in the old version) Crystal HD is a video/audio hardware decoder in the PCIe Mini Card half-height form factor. It is designed to reduce CPU utilization and allows for full HD real-time decoding support for mobile platform solutions.The BCM970015 single-chip Crystal HD advanced media processor is a low cost, low power (less than 1 W energy consumption), highly integrated solution for high definition (HD) video playback applications. It is targeted for multimedia applications such as HD playback and broadcast and other TV sources. It is excellent for use in small form factor systems that require high-end graphics support but can"t compromise power consumption or platform footprint.
