Abstract: In the data transmission of coded pixel blocks, coefficients can be arranged in blocks having a fixed mean length. Blocks not filled up are filled up with temporarily stored (4, 10) data from other blocks. In order to enable decoding to occur even in the case of interference, each of the blocks can additionally contain an address pointer information item (POI, FL) which points to addresses in a memory (10) from which the separated data components of blocks having a greater length than the mean word length are recovered and used for decoding. Due to the additional address pointer information item, however, a lower data rate is available for the image data, the channel capacity remaining the same, which leads to a reduced image quality in the case of undisturbed decoding. According to the invention, recovery pointer pairs (REC) with full word length are additionally in each case inserted between a fixed number of information data blocks, the other address pointers only comprising the LSBs of the full word length. As a result, additional data can also be injected into the data stream. <IMAGE>

Abstract: An optical connector (20) includes a ferrule assembly (22) which is adapted to be received in a plug frame (70). The ferrule assembly is held in the plug frame by a cable retention assembly (40) which is adapted to be secured to said plug frame. A leading end of the plug frame is symmetrical in an end cross-section which is normal to a longitudinal axis of the connector. After the ferrule assembly has been assembled to the plug frame, the direction of any eccentricity of the plug passageway or of an optical fiber terminated by the ferrule assembly is determined. Then the plug frame is assembled to a housing of a grip (90) such that the direction of eccentricity is aligned with a key (92) of the grip. The plug frame is capable of being assembled to the grip notwithstanding the rotational orientation of the plug frame with respect to the grip. An optical connection between optical fibers terminated by two connectors is made by inserting the grip of each of the two connectors into a coupling housing (100) so that the keys are aligned. Advantageously, portions of the connector may be factory assembled which facilitates field use of the connector to terminate optical fiber.
