For conversion of a first video signal into a second video signal of a different format, a second auxiliary data packet is generated from a header carrying location data for multiplexing a first auxiliary data packet and main data of a first auxiliary data packet in the first video signal, and is multiplexed with the second video signal. One embodiment of a computing device includes a first processor, a memory in communication with the first processor, and computer executable instructions stored in memory and executable on the first processor. The system configuration for consumer use contains additional components and optional features that enhance the system, namely: an operation center, a video distribution system, a home subsystem, including reception, selection, viewing, transacting and transmission capabilities, and a billing and collection system. Thereby, the system provides a manual of which contents and format are customized to a user company, in either electronic or paper-printed information. The present novel compounds are especially well suited for treatment of coccidiosis, and they are represented by general formula wherein R1-R6, X and A are as defined in the specification. A printing section is positioned between the preprinting section and the postprinting section.
