Mdtv technologies a quick technical fact sheet
MDTV TechnologiesA Quick Technical Fact Sheet


  • DAB

    • OFDM based

    • 1.7MHz per RF channel

    • Targeting to be the digital alternative to FM radio

    • Not necessarily targeted for mobile / handheld

    • Deployed over VHF-III in most cases, L1 band in some cases

    • All DAB services are free-to-air

  • DVB-T

    • OFDM based

    • 6MHz-8MHz per RF channel

    • Developed by the DVB Organization (Europe) as the digital replacement of analog TV (PAL)

    • Originally not targeted for mobile / handheld

    • Deployed over UHF in most cases, VHF-III in some cases

    • Considerable use of the free-to-air model


  • DVB-H

    • Based on DVB-T PHY, can use same infrastructure as DVB-T network with minimal additions

    • Adds mobility using additional FEC in the link layer

    • Adds power consumption provisions suitable for mobile using time slicing (the receiver is operated in TDD mode)

    • Very good spectral efficiency, allows up to 15 TV channels including radio and data channels

    • Uses the Pay-TV (conditional access) model, with FTA model used only in India

  • T-DMB

    • Based on DAB PHY (Eureka 147), can use the same infrastructure using minimal additions

    • Adds additional FEC in the link layer in order to achieve BER suitable for video

    • Inherently has less spectral efficiency than DVB-H and worse power consumption provisioningCan offer 2-3 TV channels per frequency


  • DAB-IP

    • Based on DAB PHY

    • Deployed over VHF-III and L1 band

    • Encapsulates the service (i.e. TV channel or data transmission) in IP packets and sends them over the DAB PHY using more robust FEC

  • ISDB-T

    • Japanese standard, uses up to 13 segments of 429KHz each. Each segment can have its own characteristics (i.e. for mobile, portable, etc.)

    • The mobile transmission is named 1-Seg and uses a single segment of 429 KHz

    • 3-seg mode is considered applicable for “portable” devices

    • Deployed over UHF mainly, with some cases VHF

  • MediaFLO

    • No legacy “parent” standard, developed by Qualcomm

    • Designed for mobile TV. Uses Turbo coding for allegedly best performance

    • Good channel switching time and video quality (equivalent to DVB-H)

    • Deployed over UHF, but newer versions of the spec. add also VHF and L


  • S-DMB

    • A hybrid network that uses satellite coverage for large, nationwide areas and terrestrial repeaters for urban regions; terrestrial technology is based on 3G networks

    • Uses a 25MHz bandwidth in the S-band (2.630-2.655GHz)

    • Used in South Korea, service started in May 1st, 2005

    • Service has around 1.5M users so far; business model in most cases is a fixed monthly fee

  • DVB-SH

    • Stands for DVB-Satellite Handheld

    • A hybrid network that uses satellite and terrestrial, architecture similar to S-DMB, will typically use the 2.167 GHz frequency and between 5-8MHz bandwidth

    • Uses COFDM technology

    • Standard is derived from DVB-H, but adds improved error correction using turbo coding

    • Became an official DVB standard in February 2007


  • CMMB

    • Chinese homegrown standard, stands for China Multimedia Mobile Broadcasting

    • Uses the 2.67 GHz frequency and 25MHz bandwidth and COFDM technology

    • Standard is based on the S-TiMi technology, a combination of satellite and terrestrial transmission

    • Service is in trials during 2007, will be commercial in 2008. Will offer 25 TV channels and 30 radio channels

  • DMB-T (China)

    • Chinese homegrown standard, brewed in Tshingua university in Beijing

    • The Chinese equivalent for DVB-T, targeted for home and portable digital TV services, but will be applied to mobile also

    • Allegedly outperforms DVB-T in terms of the minimum required C/N signal; using TDM-OFDM technology, uses LDPC code for error correction

    • Could not be adopted by the industry as the nationwide standard, will be used in principal urban locations

Dvb t for mdtv a new trend
DVB-T for MDTV – a New Trend

  • Mobile operators are launching mobile phones with DVB-T

    • This is an important trend, that shows that MNO’s are no longer hesitant from dealing with the FTA technologies, and more importantly show that they strongly believe in broadcast TV and (have a good idea) how to make money out of it.

  • The leader in this trend is VF Germany, but T-Mobile and others are expected to follow the same

  • Qualcomm is looking to drive FLO into other regions around the globe, so far without much success (mainly due to the EU blocking move)


Dvb sh

  • Alcatel has practically invented this standard and is also driving it

  • Terrestrial trial is taking place in France, satellite will be launched only in 2009

  • Alcatel has signed an agreement with ICO, an US infrastructure company specializing in satellite and terrestrial equipment, to deliver DVB-SH systems to the US market

    • Trial is expected to start in Spring 2008

  • European MNO’s are not ruling out the possibility of adopting DVB-SH
