    Abstract: Embodiments of the present invention provide a media data processing method and apparatus. The media data processing method includes: obtaining each media segment in a coding representation; and performing content protection processing on at least a part of media segments in the coding representation. In the embodiments of the present invention, a media segment in a coding representation is used as a unit of content protection, and the content protection may be performed on at least a part of media segments in the coding representation, so that protection manners of media segments in the coding representation are differentiated, so as to improve reliability and flexibility of performing the content protection on an HTTP streaming media service.

    Abstract: A method, a server, and a user terminal for providing and acquiring media content are provided. The providing method includes: receiving a file segment acquiring request sent by a user terminal, where the file segment acquiring request is generated and sent by the user terminal according to an identifier of the user terminal, and the media segment description file includes a storage address and an embedded identifier of each media file segment that is divided from media content; and providing the user terminal with a media file segment that is embedded with the identifier of the user terminal. In the technical solution of the present invention, a server no longer processes media content in real time and responds to an acquiring request of a user terminal, thereby reducing concurrent load of the server and reducing concurrent bandwidth occupied by media content distribution.

    Abstract: Embodiments of the present invention provide a frequency offset detection method and apparatus. The frequency offset detection method in the present invention includes: calibrating a frequency offset of a clock signal output by a local crystal oscillator of a network element device, and performing frequency offset detection on a tracked reference clock signal by using the calibrated clock signal output by the local crystal oscillator. The embodiments of the present invention solve a problem in the prior art that a detection result for a frequency offset of a reference clock signal is inaccurate because of an existence of a frequency offset of a local crystal oscillator and a parameter drift caused by aging, thereby improving detection precision without replacing hardware.

    Abstract: The present invention discloses a method for generating media information, a terminal, a server, and an adaptive streaming system. Media code streams of m types of code rate, which are generated by an AHS system, are divided into h groups, and tracing codes are separately embedded into code stream segments of each group. The tracing codes embedded into the code stream segments, and code stream group information are stored in a media presentation description MPD file. In a downloading process of a terminal, tracing of an end user that downloads media data is implemented.
