摘要：
The present invention relates to a method for verifying video data encoded in an encoder unit, wherein the encoder unit comprises a safe part and a non-safe part, wherein loop filtering in the encoder unit is disabled, and wherein the method (1) comprises the steps of:
- Acquiring video data in the safe part of the encoder unit (2,11,21);
- Encoding the acquired video data by a non-safe encoder in the non-safe part of the encoder unit (3,12,22);
- Decoding the encoded video data by a non-safe decoder in the non-safe part of the encoder unit (4,13,23); and
- Comparing the decoded video data with the acquired video data in the safe part of the encoder unit (5,14,24), wherein a safety focused reaction is initiated if the decoded video data does not correspond to the acquired video data, and wherein a first safety sequence is generated based on the decoded video data in the safe part of the encoder unit, wherein the encoded video data and the first safety sequence are transmitted to a decoder unit for decoding the encoded video data, if the decoded video data corresponds to the acquired video data.
- Acquiring video data in the safe part of the encoder unit (2,11,21);
- Encoding the acquired video data by a non-safe encoder in the non-safe part of the encoder unit (3,12,22);
- Decoding the encoded video data by a non-safe decoder in the non-safe part of the encoder unit (4,13,23); and
- Comparing the decoded video data with the acquired video data in the safe part of the encoder unit (5,14,24), wherein a safety focused reaction is initiated if the decoded video data does not correspond to the acquired video data, and wherein a first safety sequence is generated based on the decoded video data in the safe part of the encoder unit, wherein the encoded video data and the first safety sequence are transmitted to a decoder unit for decoding the encoded video data, if the decoded video data corresponds to the acquired video data.
