Abstract:

An audiovisual encoding system using a multipass video encoder and a plurality of one-pass audio encoders. The number of audio encoders used by the system is equal to the number of audio tracks to be encoded divided by the number of passes required for the video encoding rounded up to the nearest integer, if necessary. The system allows the video encoder and audio encoders to be used at the same time so that the encoding of the video is completed at the same time as the encoding of all audio tracks is completed, using the minimum number of audio encoders.

Abstract:

A method is provided for testing a trading system having a verification subsystem and trading environments. Each of the environments has a network interface, memory, and a matching engine executed by a processor. The method includes retrieving, by the verification subsystem, at least one defined use case. Each defined use case includes command lines. The method also includes parsing the command lines based on defined parsing rules to produce parsed command lines. Each parsed command line includes a verb specifying financial transactions. Each parsed command line also includes data fields. The method further includes mapping the verb and fields of each command line based on defined mapping relationships to generate a test case. The method also includes executing the test case to generate messages to be executed by the trading system. The method also includes reading parameters of the trading system for comparison to specified validation values.
