Abstract: A scalable hardware accelerator configured to compute video quality metrics is disclosed. In some embodiments, an accelerator for video quality metrics comprises an application-specific integrated circuit that includes a buffer memory configured to store at least a portion of a reference frame of a video and at least a corresponding portion of a distorted frame of a transcoded version of the video and that includes a processing unit configured to receive data from the buffer memory and compute a perception-based video quality metric for the distorted frame with respect to the reference frame.

Abstract: The disclosed computer-implemented method may include receiving video data to be encoded, determining pixels for a first transform unit (TU) of a first prediction unit (PU) of a square shape of the video data, storing the pixels in a buffer, performing intra-prediction for a second PU by reusing the stored pixels for a second TU of the second PU, and encoding the video data based on the intra-prediction. A system may include a video encoder and/or a tape holder apparatus. The tape holder apparatus may include a cubical tape holder to hold multiple tape cartridges in a stack, wherein a tape cartridge may be inserted into a top of the cubical tape holder. The tape holder apparatus may include a handle and a horizontal slot enabling a single tape cartridge to be pushed out from a bottom of the stack. Various other methods, systems, and apparatuses are also disclosed.
