the work is embodied in the buffer.
Does any such embodiment last "for a period of more than transitory duration"? Id. No bit of data remains in any buffer for more than a fleeting 1.2 seconds. And unlike the data in cases like MAI Systems, which remained embodied in the computer's RAM memory until the user turned the computer off, each bit of data here is rapidly and automatically overwritten as soon as it is processed. While our inquiry is necessarily fact-specific, and other factors not present here may alter the duration analysis significantly, these facts strongly suggest that the works in this case are embodied in the buffer for only a "transitory" period, thus failing the duration requirement.
Against this evidence, plaintiffs argue only that the duration is not transitory because the data persist "long enough for Cablevision to make reproductions from them." Br. of Pls.-Appellees the Cartoon Network et al. at 51. As we have explained above, however, this reasoning impermissibly reads the duration language out of the statute, and we reject it. Given that the data reside in no buffer for more than 1.2 seconds before being automatically overwritten, and in the absence of compelling arguments to the contrary, we believe that the copyrighted works here are not "embodied" in the buffers for a period of more than transitory duration, and are therefore not "fixed" in the buffers. Accordingly, the acts of buffering in the operation of the RS-DVR do not create copies, as the Copyright Act defines
