Transition from Analog to Digital Terrestrial TV

The international migration from analog broadcasting to digital terrestrial television (DTT) marches on with a significant impact on the television set market, according to In-Stat.

Many nations have announced an analog broadcast shutoff date, but how they implement this change varies. Some countries are allocating spectrum so they can transmit analog and digital broadcasts concurrently for a number of years. Other countries are rolling out DTT regionally and shutting down analog service as the roll-out is completed.

"There are now four main standards for digital television (DTV) broadcasting, with some similarities between these standards in audio and video compression, but the demodulation schemes are all different," says Chris Kissel, In-Stat analyst.

"Consumers that wish to receive free, over-the-air broadcasts must buy either a digital television with a digital tuner, or must have a set top box or converter box to receive the signal."

Recent research by In-Stat found the following:

- DTV tuner integration is happening faster in North America and Japan than it is in Europe or other parts of Asia.

- In-Stat anticipates that flat-panel displays will overtake CRTs by 2007.

- However, only 11.6 percent of all respondents to an In-Stat U.S. consumer survey plan to buy a new DTV set within the next six months.

The Cloud Imperative for Telecom Operators

The telecom sector is undertaking an update of its IT infrastructure. As demand for data continues to soar with the proliferation of 5G and new apps, network operators can't rely on their legacy hardware and network architectures. The process of "Cloudification" offers a path to reduce costs, improve efficiency and scalability, plus meet increasingly ambitious infrastructure sustainability goals. According to the latest market study by Juniper Research, cloudification spending by telecom operators will see tremendous growth in the coming years, rising from $26.6 billion in 2024 to $64.9 billion by 2028 -- that's a 144 percent increase in just four years.

However, operators must insulate mission-critical traffic when reducing power, to guarantee quality of service for enterprises," said Alex Webb, research analyst at
