The present document also contains a recommendation clause, which provides simple measures to improve interoperability between ASI equipment. The packet length can be bytes or bytes. Additionally, an ASI input should be designed with an receiver buffer that accommodates as wide a variety of ASI outputs as possible within appropriate commercial constraints.

The line driver and receiver shall be LVDS-compatible, i. The link is used by the interconnected ports to perform communication. NOTE 4 For the purpose of these masks, the rise time and delay time should be measured between -0,04 V and 0,4 V, and should not exceed 4 ns.

BS EN 50083-9:2002

Methods of measurements are given in ENchapter 3. Data are removed from this buffer at a constant rate, determined by the receiver clock rx-clk.

The basic unit of Layer-0 is the link. NOTE 4 For the purpose of these masks, the rise time and delay time should be measured between —0,4 V and 0,4 V, and should not exceed 4 ns.

Add to Alert PDF. Physical equipment such as video or audio compressors, multiplexers, modulators, etc. SSI is synchronous to the Transport Stream which is transmitted on the serial link. A version in any other language made by translation under the responsibility of a CENELEC member into its own language and notified to the Central Secretariat has the same status as the official versions. As the actual rate may deviate from the average, we introduce the peak rate as the highest rate found in the N time slices.

This code provides error checking through both invalid transmission code points and the notion of ‘running’ disparity. We use cookies to make our website easier to use and to better understand your needs. If this is not the case, the receiver buffer will overflow. This specification is similar to EN and EN It is important to notice that various parameters which are important for interoperation are not specified in this standard.

The present document assumes that the receiver clock is linked to the transmission clock, but is silent about how to achieve this in practice. The encoding rules are as follows: ENEN The inverse operations are performed in the receiver. The links are unidirectional point to point. The synchronous parallel interface is specified to cover short or medium distances, i.

The standardization of any user terminals i. The line data stream is locked to the TS data stream. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

RD at the beginning of a subblock is the calculated RD of the last sub-block. The number of bytes in the receiver buffer is shown in the right-hand curve. You may delete a document from your Alert Profile at any time. Interfaces pour les tetes de resaux pour antennes communautaires, antennes collectives par satellite et materiels professionnels a.

The Transport Packets shall be presented to Layer-2 either as contiguous byte packets, or separated by 16 dummy bytes, or contiguous Reed Solomon encoded byte packets.

RF interfaces and interfaces to telecom networks are not covered in this document. The standard deviation of the time is now ns, or about 40 times the results of Table E. The packet synchronization byte 47H or B8H is used as a byte alignment pattern which serves for initializing the serial to parallel conversion. Document Status Indicators The Green document status indicator indicates that the document is: The standardization of any user terminals i.

Therefore, to ensure correct operation, care must be taken that equipment interface circuitry of the non-inverting type is used.
