DATA COMPRESSION METHOD AND APPARATUS, AND DATA ENCODING/DECODING METHOD AND APPARATUS

Номер: WO2020135357A1
Автор: SHAO, Qinglong, GAO, Junping, PU, Yuliang, CUI, Zhenfeng

Disclosed in the present application are a data compression method and apparatus, and a data encoding/decoding method and apparatus; in the data encoding method described in the present application, an encoding block to be processed is first classified before encoding, and lossy encoding or lossless encoding is used for different types of encoding blocks to be processed, thus reducing the occupied transmission bandwidth; moreover, a decoding end uses chromaticity information to perform necessary color compensation on decoded data of a bitstream that has undergone lossy encoding, thus ensuring the fidelity of transmitted data.

Service data processing method for satellite ground application system

Номер: CN116545506A
Автор: XU LIN, ZHOU ZIQI, ZHOU XIAO, ZHANG JUNXIAO, SHAO QINGLONG
Принадлежит:

The invention relates to a satellite ground application system service data processing method, which specifically comprises the following steps: S1, an uplink system processes original data into telemetry information and issues the telemetry information to a service system, the service system performs data analysis after receiving the telemetry information, and a bidirectional filtering matching algorithm is adopted to screen out the telemetry information required by the service system; s2, the data processing module carries out satellite time reversal prevention and data redundancy prevention processing on the screened telemetry information; s3, disassembling the processed telemetry information by a data packaging module, packaging by taking parameter information as a basic data unit, and converting into service data; s4, the data pushing module pushes the service data to the front end in real time through WebSocket; and S5, the data archiving module packages and archives the business ...
