Retractable transport stream collection system and method

Abstract

The invention provides a retractable transport stream collection system and method. The system comprises a switch 1, a switch 2, a switch 3, a transport stream analysis module, a data compression module, a data decompression module, a caching module and a file packaging module. Transport streams are sent to the transport stream analysis module and the data compression module respectively through the switch 1 and the switch 2. The data compression module is connected to the caching module. The caching module is in series connection with the switch 3 and the data decompression module, and then is connected to the transport stream analysis module. The transport stream analysis module is connected to the file packaging module. Compared with the prior art, by employing the system and the method, the efficiency of transport stream collection can be substantially improved, data storage expenses of the transport stream collection can be greatly reduced, abnormal collection tasks can be recovered with the aid of the system when the collection tasks are abnormal, and original transport stream data can be provided for assisting in rapidly analyzing system abnormity reasons.

Description

technical field [0001] The invention relates to the field of data communication, in particular to a scalable transmission stream recording system and method. Background technique [0002] The MPEG organization has formulated the MPEG-2 standard for video and audio compression coding and its encapsulation format. The system layer defines the combination of audio, video and other data into transport stream specifications suitable for transmission and storage. Transport stream has the advantages of fixed packet length, good fault tolerance, high flexibility, strong scalability, and fast processing, so it is widely used in digital TV and other fields. At present, transport stream has become the standard for broadcast television system stream. [0003] The code stream involved in the transport stream can be divided into elementary stream (ES), packetized elementary stream (PES) and transport stream (TS) according to the formation process. The compression layer encodes the origi...

AI Technical Summary

Problems solved by technology

When the online collection encounters an abnormal data stream, the content will be lost and the collection task cannot be recovered, and it will be difficult to troubleshoot the cause, etc.

The disadvantages of offline recording are: the collection efficiency is low, and the task time includes the program duration and analysis, codec, file packaging, etc.; it takes up a lot of storage space, and all programs are stored when recording, and one of multiple programs is recorded. Will take up a lot of storage space when set
