Abstract

A video transcoding card includes a first transcoding assembly and a second transcoding assembly. The first transcoding assembly includes a first circuit board, first transcoding boards, and a first main electrical connector. The first transcoding boards and the first main electrical connector are disposed on the first circuit board and are electrically connected to the first circuit board. The second transcoding assembly includes a second circuit board, second transcoding boards and a second main electrical connector. The second transcoding boards and the second main electrical connector are disposed on the second circuit board and are electrically connected to the second circuit board. The first main electrical connector and the second main electrical connector are connected to each other, and the second transcoding boards are electrically connected to the first circuit board via the second circuit board, the second main electrical connector, and the first main electrical connector.
