  • Page 22 The MD8000 Series system offers a choice of three (3) platforms to best fit your network configuration:  The MD8000SX is a 2U chassis device with one (1) SWCNT-9 board for packet switching between up to six (6) Trunk and Channel boards installed in the chassis.

  • Page 23: Features

    Features The MD8000 Series Transport System has the following features:  High quality video signal transmission Uncompressed video signals (HD-SDI/SD-SDI/DVB-ASI) are IP encapsulated for transmission. Loss of any one whole packet in a row of 40 consecutive packets can be recovered using robust forward error correction and interleave technique.

  • Page 42: Hitless Switching

    Hitless Switching Hitless Switching from a primary circuit to a backup circuit requires two (2) MD8000 streams to be sent and received. These should traverse the network on diverse paths. Using the Delay Adjustment buffers in the receiving Channel Service board, packet processing for the two circuits is aligned so that the same packets from the primary and backup circuits are processed at the same time.

    Delay Adjustment Buffer The delay adjustment buffer has several functions. It provides for packet buffering in order to reproduce an accurate video/audio clock and to absorb any network induced jitter. The Loading Base point setting must accommodate these functions. Additionally, for Hitless switching both the primary and protect path packets will be buffered at the receiving line board so that they can be synchronized and aligned by sequence number.
