Abstract

The invention discloses a TLV data generation method, a TLV data reading method, an intelligent device and a storage medium, and the TLV data generation method comprises the following steps: obtaininga descrambling key corresponding to first TLV data, and generating second TLV data according to the descrambling key; generating mixed TLV data according to the second TLV data and the first TLV data, and storing the mixed TLV data. According to the method, the data storage process can be optimized, the descrambling and encrypting processes of the data are reduced, the scrambled data are directlystored, bandwidth resources occupied by data processing in the storage process are reduced, the data storage efficiency can be guaranteed in intelligent equipment with different hardware configurations, the data storage efficiency is improve, and the reduction of the storage efficiency caused by bandwidth bottleneck is avoided.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a TLV data generation method, a reading method, an intelligent device and a storage medium. Background technique [0002] When existing smart devices use the PVR (Personal video recorder, personal video recording) function, the recorded data stream needs to be encapsulated into TLV (Type-length-value, type-length-value structure) format after scrambling When storing the TLV data in the storage module, it is necessary to descramble the scrambled data, and encrypt and store the data stream after descrambling. And in order to ensure the security of data processing, the descrambling and re-encryption of the data stream need to be processed in TEE (Trusted Execution Environment, Trusted Execution Environment). That is, when the recorded audio and video data is stored in a storage medium such as a hard disk, multiple data processing procedures need to be performed. During the data proc...
