Abstract: A method of generating timestamps for isochronous data includes locking a data stream time and an isochronous network time to a local clock signal such that a bi-directional mapping may be made between the two time domains. Timing information is extracted from both IEEE 1394 based data packets and a conventional house reference signal in order to obtain scale and offset factors that exist between the two signals. The scale and offset factors are applied to a generated video clock signal in order to predict a future video time in terms of IEEE 1394 time.

Abstract: A method of distributing video reference signals as isochronous data includes distributing a house reference signal among various audio and video devices using isochronous network packets that exclusively contain isochronous header information rather than header information accompanied by audio and/or video data. Because the data associated with a house reference signal typically represents an unused “video black” signal, such data may be discarded without detrimentally affecting to the reference signal.

Abstract: In a device for the cooling of optoelectronic components (1) with an evacuated cooler housing mounted on a base, in which there are provided at least one holding device for components (1) which is thermally coupled with the cold station of a cooling unit through at least one flexible metal band (19), the housing of the cooling unit is for vibrational decoupling connected with the cooler housing and sealed against atmospheric pressure through ring-shaped rubber-elastic sealing means. The at least one holding device (8), through a flexible metal band (19) thermally coupled to a cold station, of a refrigeration unit, that protrudes into the cooler housing, comprises a retaining plate (17) which is arranged on one end of a thin-walled, essentially prismatic or cylindrical body from a thermally poorly conductive material, specifically epoxy resin panels (9, 10, 11, 12).
