  • Page 76 Base Unit User Guide Issue 1 Tech-X Flex™ received the referenced frame before the B-frame can be decoded, making the frame order different from the actual display order. Therefore, B-frames can cause a delay in the decoding process, because the decoder must buffer the input while reordering the frames for display. Of the three, the loss of a B-frame generally causes the least impact to picture quality.

  • Page 77: About Mpeg Transport

    Tech-X Flex™ Base Unit User Guide Issue 1 Audio compression has some similarity to video compression, in that techniques may be used to eliminate redundant data. Furthermore, audio exhibits the concept of “masking,” where one frequency may mask another and the human ear is unable to perceive it. Because it is unnecessary to transmit any data for sounds that will never be heard, the removal of this data from the original audio stream provides further possibilities for data reduction.
