因為手持式數位影像廣播(Digital Video Broadcasting – Handheld DVB-H)技術的出現，使得在手機或可攜式裝置上收看數位廣播影像節目變的有可能。而原本的地面數位影像廣播(Digital Video Broadcasting – Terrestrial)，由於傳送的資料是連續的且每個節目分配到的頻寬(bit rate)不多因此不同的頻寬內會有不同的頻道在使用及不同的節目，所以再同樣的時間內接收器可以收到不同頻道的節目但收看者只解碼出自己要看的節目位元串流資料，因此其它接收到的節目位元串流資料因為不是接收者要收到的節目所以不需要解碼在效率上來看有點浪費功率，且由於DVB-T是給固定的裝置接收的所以採用8K正交分頻多工編碼的方式，涵蓋的範圍比較大但比較不利於高速移動的時候接收信號，由於如果要在手機或手攜式的裝置上接收影像節目，必需要持久的電力來維持。
因此DVB-H採用分時方式的資料傳送形式，把原本通道頻寬是由其它節目共同分配享有的，現在只可以讓某一個節目使用全部的頻寬所以讓節目傳送的位元率提高了，相對的減少傳送的時間，但跟DVB-T一樣在單位時間內(cycle time)所傳送的資料是一樣多的，由於DVB-H採用分時多工的方式傳送資料所以接收器只在該節目傳送的時間內接收該筆資料，而其它時間則不接收然後在等一個單位時間內(cycle time)，該節目的資料再傳送時在接收，如此開關開關達到收到整部節目的資料，並大量的減少持續接收節目所消耗的功率，接下來由於DVB-H採用4K正交分頻多工編碼的方式，雖然涵蓋的範圍沒有DVB-T大但對高速移動的時候接收信號時的效果會比較好。

To meet the Commercial Requirements set by the DVB-M (CM) group for a new DVB transport mechanism, a Call for Technologies was released by the DVB in January 2003. Based on the responses received and using the technology elements of several proposals (plus some development work carried out inside the DVB-H group) a full DVB-H concept has been composed by combining elements in the Physical and Link layers. The DVB-H group took into account the guidance and requests set by the DVB-TM and DVB-SB for the new standard.
Although the DVB-T transmission system has proven its ability to serve fixed, portable and mobile terminals; handheld terminals (defined as light-weight, battery-powered apparatus) require specific features from the transmission system serving them:
• The transmission system shall offer the possibility to repeatedly turn the
power off to some parts of the reception chain. This will reduce the average
power consumption of the receiver.
• The transmission system shall ensure it is easy for receivers to move from
one transmission cell to another while maintaining the DVB-H service.
• For a number of reception scenarios; indoor, outdoor, pedestrian and inside a
moving vehicle, the transmission system shall offer sufficient flexibility and scalability to allow the reception of DVB-H services at various speeds, whilst
optimizing transmitter coverage.
• As services are expected to be delivered in environments that suffer high levels of man-made noise, the transmission system shall offer the means to mitigate their effects on the performance of the receiving terminal.
• As DVB-H aims to provide a generic way to serve handheld terminals in various part of the world, the transmission system shall offer the flexibility to be used in various transmission bands and channel bandwidths.
