Abstract
A video processing device is configured to: generate a frame number which represents a frame to which video data belong and a value of which changes between consecutive frames; for each data block of a predetermined size in the video data, embed the frame number in a portion of the data block; write, in a frame order, the video data into a memory by using a data block as a unit; successively read data blocks written into the memory; and generate an abnormality determination signal indicating frozen video in a case where a state in which the frame number in the data block currently read does not change from the frame number in the data block read last time continues for a predetermined number of times or more.
Claims14
A video processing device, comprising:
- a generation part, generating a frame number which represents a frame to which video data belong, wherein a value of the frame number changes between consecutive frames;
- an embedding part, for each data block of a predetermined size in the video data, embedding the frame number in a portion of the data block;
- a writing part, writing, in a frame order, the video data into a memory by using a data block as a unit;
- a reading part, successively reading the data blocks written into the memory;
- and
- a determination part, generating an abnormality determination signal indicating frozen video in a case where a state in which the frame number in the data block currently read by the reading part does not change from the frame number in the data block read last time has continued for a predetermined number of times or more.
