BASEBAND<br />
Limited alternatives for service creation<br />
Service creation is the core business for digital TV operators. Operators<br />
receive compressed content from broadcasters, mainly from satellites,<br />
and use these services as building blocks to create their own bouquets.<br />
Designing a new multiplex by staying in the compressed domain<br />
is theoretically possible, but in practice only applicable to limited<br />
turnaround services. This is due to the complexity of manipulating MPEG<br />
compressed video: MPEG is very efficient for bandwidth optimization<br />
but doesn’t lend itself to program customization. In particular, inserting<br />
new content — commercials, local news — is not a frame accurate<br />
workflow, whether performed manually via a GPI or automatically with an<br />
automation system.<br />
In order to achieve real content differentiation that will attract viewers<br />
and as a result advertisers, digital TV operators usually have to adopt<br />
baseband architecture for uncompressed video processing.<br />
A baseband process offers many features for designing value-added<br />
content, but it is complex and the investment and operational costs<br />
are high. It also demands the right level of expertise, which has a price.<br />
Another drawback is the successive decoding and re-encoding, which<br />
negatively impacts video quality.<br />
Operators have been looking for a solution that offers architectural<br />
simplicity while also enabling them to efficiently design differentiated<br />
content.<br />

COMPRESSED<br />
Breakthrough in processes and economics<br />
Based on these requirements, <strong>Thomson</strong> <strong>Video</strong> <strong>Networks</strong> has developed<br />
the Sapphire, an innovative platform that leverages our extensive<br />
experience in MPEG processing:<br />
››<br />
Sapphire allows frame-accurate splicing and logo/graphic insertion<br />
in the compressed domain, resulting in fully deterministic and<br />
seamless playout and program switching.<br />
The goal here is not to deliver the sophisticated effects (fade in/fade out,<br />
squeeze back, wipe or voice over) found in baseband servers. It is to<br />
achieve unsurpassed insertion: clean, seamless, frame accurate MPEG<br />
insertion.<br />
››<br />
The 1 RU platform integrates a number of processes that often require<br />
multiple boxes with other compressed domain solutions: not only a<br />
native server but also a splicer, router, character generator, and logo<br />
inserter.<br />
Digital TV operators can add commercials, logos, combine live services<br />
in a new bouquet, and inject personalized content. In short they can<br />
perform playout tasks in a compressed mode and benefit from flexibility<br />
that is comparable to baseband. Sapphire’s simplicity, lightness and ease<br />
of operation, however, spare the operators from the constraints imposed<br />
by a baseband system.<br />
››<br />
From a service perspective, the elimination of unnecessary encoding<br />
and re-encoding naturally benefits video quality, which remains at the<br />
level originally delivered in incoming sources.<br />
››<br />
For the processing of MPEG-2, H.264, SD and HD content, it is<br />
possible to handle up to 20 channels in a single box. This is a true<br />
industry revolution in terms of processing architecture and economy.<br />
A channel in a box<br />
With Sapphire, digital TV operators can conciliate high-service<br />
customization and quality transparent program switching, while improving<br />
investment and operational cost.<br />
The addition of new SD/HD channels is a real breakthrough since it<br />
means that a single platform can support one, five or a dozen new<br />
channels at a marginal cost compared to having to duplicate the systems.<br />
Sapphire defines a new business model where service cost and breakeven<br />
levels are significantly lower.<br />
Moreover, evolving to HD often implies a forklift upgrade of the legacy<br />
system: this is the perfect opportunity to choose a new generation<br />
platform, associating high density, flexibility and scalability.<br />
Digital TV operators now have an effective alternative to limited<br />
customization in a compressed mode versus complex editing in<br />
baseband.<br />
