Mobile Broadcast Solution
Server and Network Solutions
A vital part of mobile TV delivery is the server solution. It controls and protects content streams between content providers and end users, delivers service information, provides means for purchasing and charging for services, and may be used to protect the service.
The solution plays a major role in the interoperability between the device and the content stream, ensuring that the mobile TV client in the device can discover and utilize services using the DVB-H network.
The Nokia Mobile Broadcast Solution is based on IP datacasting over DVB-H, a mobile optimization of the technology that drives digital television, and consists of three tightly integrated major elements:
- The Broadcast Service Manager controls the broadcast and end-to-end protection of streams and also generates the electronic service guide.
- The Broadcast Encapsulator is the gateway that enables broadcast delivery of IP content over DVB-H. These IP encapsulators may also perform the encryption of paid services.
- The Broadcast Account Manager lets the user buy rights for the consumption of protected content and produces charging data of the purchase transactions for billing purposes.
The solution has three major features:
- Streaming control: Enabling both network-wide and regional broadcasts from several content providers.
- Electronic service guide: Generation and broadcast of the service metadata so that consumers can browse available services, view service descriptions and purchase new services.
- Service protection and purchase: End-to-end control of stream encryption if IPsec is used, generation of decryption keys, and delivery of keys to consumers in a billing-integrated manner.
DVB-H Networks
DVB-H broadcast networks are an optimal medium for mobile TV services. These networks offer a relatively inexpensive infrastructure with key handheld reception features such as time slicing for power consumption.
Nokia promotes DVB-H networks consisting of SFN (single frequency network) cells. In an optimal deployment, these cells may deploy one to six low power transmitters and four to ten radio frequency repeaters. A cell diameter might extend up to 60 km and in practice one cell could cover the commuter area of a big city. The SFN cells are economically advantageous and allow effective frequency re-use.
The air interface between the devices and the network-side solution allows for multi-vendor implementations of the mobile broadcast architecture.
New! Nokia Mobile Broadcast Solution 3.3 (Availability 2Q08)
The Nokia Mobile Broadcast Solution (MBS) is a globally deployed DVB-H server platform for commercial mobile TV services. MBS release 3.3 and supports the following features:
- OMA BCAST 1.0 standard
- DVB IPDC Release 1.0 set of specifications submitted to ETSI
- OMA BCAST Smartcard profile
- Service protection using IPSec, SRTP, and ISMACryp
- Both the IPv4 and IPv6 modes
- Backwards compatibility with earlier MBS and DVB-H Mobile TV Implementation Guidelines
The MBS 3.3 solution thus provides full flexibility and interoperability in a widely-deployed solution. The air interface is fully described in the DVB-H Mobile TV Implementation Guidelines to facilitate the availability of compatible terminal implementations from various vendors. MBS 3.3 is also being tested with various different terminal implementations on different test events.
