In sum, no case law or other authority dissuades us from concluding that the definition of "fixed" imposes both an embodiment requirement and a duration requirement. Accord CoStar Group Inc. v. LoopNet, Inc., 373 F.3d 544, 551 (4th Cir. 2004) (while temporary reproductions "may be made in this transmission process, they would appear not to be 'fixed' in the sense that they are 'of more than transitory duration'"). We now turn to whether, in this case, those requirements are met by the buffer data.
Cablevision does not seriously dispute that copyrighted works are "embodied" in the buffer. Data in the BMR buffer can be reformatted and transmitted to the other components of the RS-DVR system. Data in the primary ingest buffer can be copied onto the Arroyo hard disks if a user has requested a recording of that data. Thus, a work's "embodiment" in either buffer "is sufficiently permanent or stable to permit it to be perceived, reproduced," (as in the case of the ingest buffer) "or otherwise communicated" (as in the BMR buffer). 17 U.S.C. § 101. The result might be different if only a single second of a much longer work was placed in the buffer in isolation. In such a situation, it might be reasonable to conclude that only a minuscule portion of a work, rather than "a work" was embodied in the buffer. Here, however, where every second of an entire work is placed, one second at a time, in the buffer, we conclude that
