TV Transmission over Internet

• Receivers connected over Ethernet with single wiring

• Efficient bandwidth utilisation: Only the currently needed bandwidth is used for each viewer

• Input: With a specific NIM all DVB modulation types (-T, -S, -C): TV and radio services; ASI transport stream

• Output: Several concurrent services (TV or radio) over Ethernet

• Individual multicast adresses for each service (SPTS), unicast, broadcast

• Netto data rates up to 100 Mbit/s

• SAP and SDP announcement of the services

• Transport over UDP/RTP

TV over Internet is a solution that becomes increasingly important when planning the TV supply for new buildings: A daily challenge for the providers of classical cable head-ends.

Supplying the TV viewers over IP-TV saves costs and efforts, because there's only a single wiring necessary. Moreover, the available bandwidth is exploited optimally in the multicast mode: Thanks to the SPTS mode, each viewer demands the currently needed bandwidth only.

IP-TV is an attractive solution for distant locations and for the connection of different buildings, too. Over a low-priced and stable ethernet connection, the IP-TV head-end is able to provide also distant receivers with TV signals.

To transform the incoming DVB signal to an IP-enabled ethernet stream and to make it receivable for the subscriber's IP network, our IP-core is a number one choice.

The IP-core works with the most important standard: RTP. With RTP, video, audio and text data streams can be encapsulated and sent over IP-based networks.

According to the requirements, the data trans-mission may run over broadcast (data transmission to all destinations), unicast (individual data stream) or multicast (smaller network load, SPTS mode); for the distribution, additional Ethernet switches are needed.

The data streams can be received by a computer with video player software, or by an IP-TV-enabled set-top-box that passes the signals over to the television. Other mobile end devices with internet reception may be qualified for IP-TV, too.
