A digital printing device, comprising a suction transport means (). The suction transport means () comprises a transport belt () used for transporting a sheet material. At least one first suction box (), which is used for sucking the sheet material on the transport belt () by means of negative pressure during transport, is provided in the space defined by the transport belt (). Multiple first suction holes in communication with the first suction box () are provided on the transport belt (). At least one side of the first suction box () is provided with a movable door () which moves in a direction perpendicular to the transport direction to make the first suction box () fit the sheet material to maintain a negative pressure state. Using the transport belt () during printing, the digital printing device avoids the problem of poor registration accuracy, and improves the printing effect.

The present disclosure discloses a method and a device for bandwidth self-adapting data ranking protection. The method comprises: performing redundancy protection computation on a data block to be transmitted so as to generate a redundant code of the data block, and setting a priority for the redundant code; determining whether bandwidth occupied by a redundant code with a highest priority is greater than current residual bandwidth; if the bandwidth occupied by the redundant code with the highest priority is not greater than the current residual bandwidth, carrying the redundant code with the highest priority in the current residual bandwidth; otherwise, according to a descending order of the priority, searching in residual redundant codes for a redundant code whose data amount is less than or equal to the current residual bandwidth, and carrying a found redundant code in the current residual bandwidth. The present disclosure improves the error tolerance of a system.
