In an embodiment, an integrated circuit comprises a decrypt unit configured to decrypt an encrypted, compressed video stream; an on-chip buffer; and a decompressor coupled to the decrypt unit and the on-chip buffer. The decompressor is configured decompress the video stream, and to store a first portion of each of a first plurality of frames decompressed from the video stream in the on-chip buffer. The decompressor is further configured to store a remaining portion of each of the first plurality of frames in an external memory, wherein each frame as stored in the external memory is incomplete because the first portion is not stored in the external memory.
