CTOnews.com, November 5, CTOnews.com learned from Huawei data storage official account that recently, the group standard "Evaluation Indexes and methods of Video Image recompression Technology" has been released, which has established a comprehensive evaluation system for evaluating video image recompression performance in the field of public safety. Under the guidance of this group standard, Huawei intelligent video storage OceanStor IVS3800 has passed the evaluation of the Chinese Academy of Metrology, becoming the first example in the video storage field to pass the group standard.

In the past, the lack of group standards has brought problems that can not be ignored in the video storage industry, such as video image compression coding technology differences, resulting in uneven storage effects. The public safety industry urgently needs an objective evaluation system to quantify the performance of video image compression technology and the deviation of intelligent analysis results after video image compression, and to cover the current mainstream standards. Under this background, the group standard of "Evaluation Indexes and methods of Video Image recompression Technology" came into being.

The group standard comprehensively evaluates the recompressed video image through three categories of indicators: subjective quality evaluation, objective quality damage and intelligent analysis, and rates these three indicators according to a score of 1 to 5. The higher the score, the better the quality. After being evaluated by the Chinese Academy of Metrology, Huawei's intelligent video storage OceanStor IVS3800 has achieved excellent scores, such as an average picture sample quality score of 4.92, making Huawei the first vendor in the video storage field to pass the group standard.

It is worth mentioning that Huawei intelligent video storage Ocean [Road] Stor IVS3800 realizes the secondary coding of video images based on the combination of hardware and software coding, which makes the key targets lossless and encodes the background depth, realizing that 1TB can be used as 3TB and save up to 70% of storage space.
