DVB makes play for IP delivery
November 20, 2013 13.58 Europe/London By Julian Clover
The DVB has placed a marker for IP delivery standards with the ratification of a new DVB-GSE-Lite (Generic Stream Encapsulation) specification.
At the 75th meeting of the DVB Steering Board gave approval for a completely functional subset of DVB-GSE that the Geneva-based organisation said was designed to lower the cost of consumer receiver equipment.
The DVB-GSE protocol allows for efficient encapsulation of IP and other network layer packets over the second generation DVB physical layer specifications – DVB-S2, DVB-C2, DVB-T2, and DVB-NGH. The first generation of DVB standards only supported data transport using the MPEG format with a Transport Stream packet multiplex (MPEG-TS). DVB-GSE maximizes the efficiency of IP datagrams transport, thereby reducing the overhead by a factor of 2 to 3 with respect to DVB-MPE over MPEG-TS. This is achieved without any compromise of the functionalities provided by the protocol owing to the variable length Layer 2 packet size that is suited to IP traffic characteristics.
“DVB strives to provide up-to-date market solutions with is specifications and the GSE-Lite profile is a perfect example of this work. This new specification will enable the creation of cost savings for consumers purchasing receiver equipment designed for DVB second generation standards,” said Peter Siebert, Executive Director, DVB.
The GSE-Lite profile has been conceived to provide a simple, yet completely functional sub-set of DVB-GSE. The new profile reduces the memory and processing requirements at both the transmitter and the receiver.
