Software-creating portion 11 creates update data and version-up data and supplies them to a receiver 20 through a delivery portion 13 or a server 15. The update data includes pieces of revision information of the version-up data after a period of time of each of their applications. Revision-information-processing portion 31 supplies revision information relative to software in a memory 34 to rewriting portion 33 and maintains remaining revision information. Data-revising portion 32 extracts revision information relative to the version-up data that is supplied through interfaces 25 and 26 from revision information maintained in the revision-information-processing portion 31, revises it to the latest one with it reflecting the version-up data, and then supplies it to the rewriting portion 33. The rewriting portion 33 rewrites the software in the memory 34 with the revision information and the version-up data thus supplied. This allows the software to be rewritten in which its latest condition is always realized.
摘要:
A video signal transmitting apparatus is arranged by a multiplexing unit for multiplexing digital R (red), R (green), B (blue) video signals in a time divisional manner; and for inserting a synchronization corresponding signal into the digital R, G, B video signals during the multiplexing operation to thereby output the digital R, G, B video signals with the synchronization corresponding signal. Since such a timing signal for notifying the multiplex timing is also contained in the transmitted analog R, G, B signals, the timing signal required to demultiplex the digital R, G, B video signals which have been multiplexed in the time divisional manner is no longer transmitted irrespective of the video signal when the video signal is transmitted. Accordingly, neither the transmitting apparatus, nor the transmission path is required by which the timing signal is transmitted.

The present invention relates to a flat slide valve characterized in that a pair of spacers and a slide board having connecting ports and pressure balancing holes are fitted intimately between two guide plates having valve holes and pressure balancing holes, with the thickness of said slide board being formed slightly thinner than that of the spacers, and that the pressure balancing holes for preventing augmentation of controlling power of the slide board by fluid pressure are formed in communication with the corresponding valve holes in said two guide plates and said spacers.
