Content stream processing

A method for content stream processing, the method comprising:

• performing event marking on a content stream to obtain first trigger timing information of a target event in the content stream;
• coding the content stream to obtain a coded content stream, the coded content stream including second trigger timing information of the target event in the coded content stream;
• obtaining stream time change information that indicates a timing change between a first time stamp of target frame information in the coded content stream and a second time stamp of the target frame information in the content stream;
• and
• transmitting the coded content stream based on the first trigger timing information and the stream time change information, the second trigger timing information of the target event in the coded content stream being determined based on a combination of the first trigger timing information and the stream time change information.

An information processing apparatus, comprising:

• processing circuitry configured to:
• receive a coded content stream of a content stream from a server;
• obtain second trigger timing information of the coded content stream, the second trigger timing information being determined based on a combination of first trigger timing information of the content stream and stream time change information, the stream time change information indicating a timing change between a first time stamp of target frame information in the coded content stream and a second time stamp of the target frame information in the content stream, the first trigger timing information indicating a target event in the content stream, and the second trigger timing information indicating the target event in the coded content stream;
• decode the coded content stream;
• play back the decoded content stream;
• and
• perform, when the decoded content stream is played to the target event indicated by the second trigger timing information, specified processing corresponding to the target event.
