Problems solved by technology

This will lead to the following problems: Some special characters, such as "", "&", "$", etc., may be processed by the server but not recognized by the client, or the client thinks that these characters have special meanings and cannot as session identifier
If the session identifier generated by the server contains such special characters, the client cannot process the session identifier (or consider the identifier invalid), resulting in failure to establish the RTSP session

Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] see figure 1 As shown, a method for generating a session identifier in a real-time streaming protocol comprises the following steps:

[0019] Step S101, receiving the "session establishment" request (that is, "SETUP" request) sent by the client; the "session establishment" request includes the character set information supported by the client - "SessionIdCharSet", which is used to identify The set of characters supported by this client that can form session identifiers.

[0020] Step S102, judging whether the number of characters in the character set information is greater than or equal to...

Abstract

The invention provides a method and a device for generating a session identifier in a real time streaming protocol (RTSP). The method comprises the following steps: receiving a session establishing request sent by a client, wherein the session establishing request comprises character set information supported by the client; judging whether the number of characters in the character set information is larger than or equal to a first preset threshold value; if the number of characters in the character set information is larger than or equal to the first preset threshold value, generating the session identifier according to the character set information. According to the method and the device for generating the session identifier in the RTSP provided by the invention, all generated session identifiers can be processed and identified by the client, so that the successful establishment of an RTSP session between the client and a server side is effectively ensured.

Description

technical field [0001] The invention relates to the field of multimedia technology, in particular to a method for generating a session identifier in a real-time streaming protocol and a device for generating a session identifier in the real-time streaming protocol. Background technique [0002] RTSP (Real Time Streaming Protocol, real-time streaming protocol) is an application layer protocol in the TCP / IP protocol system. RTSP is a multimedia streaming protocol used to control sound or video. The protocol uses a client / server model and is a text-based protocol for establishing and negotiating a live streaming session between a client and a server. [0003] In the RTSP protocol, the session identifier (Session Identifier) ​​is used to uniquely identify an RTSP session. The definition of the session identifier in the RTSP protocol is: a character string of any length that is not directly readable, and linear spaces must be URL-escaped. That is, the session identifier can be ...
