摘要： This specification describes technologies relating to imparting real-time priority-based network communications in an encrypted session. In general, aspects of the subject matter described can be embodied in methods that include establishing, based on cryptographic information in a reserved, random-data portion of a handshake communication, a session, receiving parameter values relating to a sub media stream, included in a header of a network communication, storing the parameter values, obtaining state information and a data payload included in a second network communication, identifying, from the state information, a purpose of the second network communication, and whether a header of the second network communication includes one or more new values corresponding to one or more of the parameters, updating one or more of the stored values based on the one or more new values, and processing the data payload based on the identified purpose and the stored parameter values.

摘要： This specification describes technologies relating to imparting cryptographic information in network communications. In general, aspects of the subject matter described in this specification can be embodied in methods that include identifying a location in a pre-defined portion of a network communication to be sent in a client-server environment, wherein the pre-defined portion is reserved for random data, inserting cryptographic information into the pre-defined portion of the network communication at the location, and sending the network communication in the client-server environment to facilitate modifying interactions in the client-server environment based at least in part on a result of processing of the cryptographic information; and on a receiving side, receiving cryptographic information inserted into the pre-defined portion of the network communication in the client-server environment, identifying the location, processing the cryptographic information, and modifying interactions in the client-server environment based at least in part on a result of the processing.

摘要： When a user selects to seek to a point in a non-indexed media file, a search starts for the beginning of the frame. Using a search algorithm, the bytes surrounding the selection point are examined to find data equal to a known frame beginning indicator. Once such a byte is found, a subsequent test is performed on the next byte to determine if it contains a valid frame length. The system examines the byte at this length to determine if it contains a value that points to the frame beginning indicator under examination. If such a pointer does exist, the system concludes that the byte with the value equal to a known frame beginning indicator is likely the byte beginning the frame. Additional tests may be performed on the bytes surrounding this frame to increase the confidence level that it is, in fact, a valid complete frame.
