Mobile digital television (MDTV) involves delivering video content over a wireless protocol to a handheld device, be it a phone, games console, personal media player (PMP), car navigation system, digital camera, or via USB dongle to a laptop computer.
MDTV can be delivered in two forms: streaming and broadcast.
- Broadcast is live TV delivered over satellite or terrestrial towers, enabling the same signal to be broadcast across a large area regardless of the number of people watching.
- Streaming MDTV is delivered to mobile phones over a mobile operator’s cellular network, and is capacity-constrained in that there is a direct relationship between the number of people watching and the bandwidth of the mobile phone networks’ streaming servers.
It is therefore understandable that it is in broadcast mobile TV where analysts are predicting the greatest growth.
Our world-leading mobile TV products have been built on our strength in DAB and T-DMB, which has enabled us to now offer low-cost third-generation mobile TV chips for handheld devices capable of receiving T-DMB and DAB-IP transmissions.
