A few quotations in fact:

"Users will be able to receive a new service from Tricolor TV while in public places - for this they will need to download and install on their mobile device (smartphone or tablet running Android or iOS) a special application with a user-friendly interface. They will be able to watch TV channels in high quality through a local Wi-Fi network connected to a node on the basis of an inexpensive and compact satellite set-top box that receives these channels directly from the satellite ... "

"On the transmitting side ... IP streams [channels] are converted from unicast to multicast, packaged in a DVB transport stream and transmitted through the satellite as part of a standard platform running in DVB-S2."

"The receiver decodes DVB-S2 transport stream, pulls out original IP packets from it and transfers it to smartphones, tablets or other devices intended for working with IP through a standard Wi-Fi access point or home router." Live content is processed and retransmitted " On the fly ", while VOD content (video on demand) is stored for access at any convenient time."

"Tricolor TV" and Eutelsat really reached an agreement on launching a new service. However, it is too early to speak about it in more detail. Now the service is under development. More details about the launch date and the service itself will be discussed later, "said Ulyana Rasskazov, spokesman for Tricolor TV, ComNews.

Data Carousels and object carousels

One of the main differences between DSM-CC in a digital TV scenario and DSM-CC as it was originally intended to be used is the nature of the network. Originally, DSM-CC was intended to be implemented using some kind of RPC mechanism. In this model, objects would reside on one node in the network and any other node that needed to manipulate them would make an RPC call to the node containing the object.

Broadcast systems are by their very nature one-way, however. Data is sent from a transmitter (the digital TV head-end) to a receiver (the set-top box or IDTV) and the receiver can't request specific data from the transmitter. This means that a receiver can't request a specific file from the server, like a PC can request a file from the network or from its hard disk. Given that a receiver can't access data in the normal way, another solution has to be found.

The solution is actually quite a simple one - the broadcaster periodically transmits every file in the filesystem, and the receiver waits for the file it wants. File operations on the receiver tell it which files it should look for in the broadcast. The best example of this kind of solution is a teletext system: each page has a unique number, and each page is transmitted in turn. When the user enters a page number, the TV must wait for that page to be broadcast before it decodes and displays it. This type of solution is known as a carousel - every page goes round it turn, and the receiver must wait for that page to come round again in the broadcast before it can use it. Of course, this solution is not terribly efficient, and later in this tutorial we'll examine ways of improving performance.

In DSM-CC, data is transmitted in blocks called modules rather than in pages, but the principle is the same. The data to be transmitted is split up into modules, some description of that module is added and then each module is transmitted in turn.
