Method and system for realizing simultaneous decoding and transcoding output of TS streams

Abstract

The technical scheme of the invention discloses a method and system for realizing simultaneous decoding and transcoding output of TS streams, and the method comprises the steps: receiving a TS code stream, carrying out the demultiplexing of the TS code stream, and obtaining PES / ES audio and video data with a packaging format; receiving the PES / ES audio and video data with the packaging format, anddecoding the PES / ES audio and video data with the packaging format to obtain de-packaged audio and video data; receiving a reading instruction for reading the card number of the intelligent card, andinputting the card number of the intelligent card into the graphic data; receiving the audio and video data and the graphic data, and superposing the audio and video data and the graphic data; and outputting and displaying the superposed data. Therefore, the code stream can be decoded and output, and the hotlinking phenomenon can be prevented and information protection can be performed on the decoding and output process by setting the card number and acquiring the card number on the audio and video data in the decoding and output process.

Description

Technical field[0001]The present invention relates to the field of digital signal processing, in particular to a method and system for realizing simultaneous decoding and transcoding output of TS streams.Background technique[0002]With the development and popularization of networks, traditional wired digital set-top boxes are gradually eliminated, and IP set-top boxes are gradually replaced. With the rapid development of IPTV, there is an increasing demand for TS (Transport Stream) to IP stream conversion, but the security problem of program sources has always existed. Most of the current solutions on the market just simply send the code stream through IP for network users to watch. The current technology cannot observe in real time whether the output IP stream is abnormal, such as stuck, and it is easy to be stolen. Chain (hotlinking refers to the content that the service provider does not provide services, bypassing other beneficial end user interfaces (such as advertisements) thro...

Problems solved by technology

Most of the solutions currently on the market simply send the code stream through IP for network users to watch. The current technology cannot observe whether the output IP stream is abnormal in real time, such as freezing, etc., and it is easy to be stolen. Chaining (hotlinking refers to content that service providers do not provide services themselves, bypassing other beneficial end-user interfaces (such as advertisements) through technical means, and directly providing end users with service content of other service providers on their own websites , to defraud end users of browsing and click rates)
