BS EN 61883-4:2005

What is this BS EN 61883-4 - Consumer audio/video equipment about?  

BS EN 61883-4 discusses consumer audio/video equipment and digital interface with a focus on MPEG2-TS data transmission. BS EN 61883-4 is the fourth part of the BS EN 61883 multi-series on consumer audio/video equipment that describes the packetization and the transmission timing for MPEG2 transport streams for the IEEE 1394 digital interface. BS EN 61883-4 describes the specifications for the IEEE 1394 packet, the CIP header, and the transmission timing for use with the transport stream as specified in prETS 300 468. This explanation is based on the transport stream as specified in DVB. 

Who is BS EN 61883-4 - Consumer audio / video equipment for? 

BS EN 61883-4 on consumer audio /video equipment is useful for: 

• Manufacturers of products that provide audio output (televisions, phones) 
• Audio equipment manufactures  
• Audio programmers  
• Music producers 
• Sound technicians 
• Recording and dubbing studios  
• Regulatory bodies 

Why should you use BS EN 61883-4 - Consumer audio / video equipment?  

The timestamp in the source packet header is used by isochronous data receivers for reconstructing the correct timing of the TSPs at their output. The time stamp indicates the intended delivery time of the first bit/byte of the TSP from the receiver output to the transport stream target decoder.  

BS EN 61883-4 discusses the construction of IEEE 1394 packet, a packetization source packet of the MPEG2-TS data stream, CIP header, transmission of isochronous packets, and buffering in the receiver. This will help you with the transmission timing for MPEG2 transport streams.
