Day 3 Session Highlight: Content Creation for HDTV
High Definition television has come of age and with it a growing demand for HD programming.
That was the message from the session ‘Content Creation for HDTV’ at the ABU Digital Broadcasting Symposium in Kuala Lumpur.
Participants heard that the transition from Standard Definition to HD has faced challenges from three main aspects: production, technical and commercial. File-based production has brought an environment where the
process of content creation is dictated by technology. For example, HD brings out fine detail in the picture and to meet this requirement more time, skill and id required for makeup, set design and costume maintenance.
The session heard that international collaboration in HD production has already taken place in Malaysia with local production companies and a couple of international channels. Relationship building has forged cooperation with producers from different regions. HD production
in Asia tends to be undertaken by producers from the West and there were calls for change, to use more Asian producers to make the content more authentic.
Another view, posited by EBS-Korea was that broadcasters must also consider viewers who do not have HD receivers. Cropping takes place when down-converting from HD to SD and subtitles are often too small to read in SD. Producers were advised to make two different versions so content is enjoyed by all viewers.
An important aspect of performance was that it should reduce capital and operating expenditure and standards selection was also based on economic drivers as obtaining licences for spectrum could be costly.
The session on Image Acquisition for HD,3DTV and Beyond revealed that significant developments have taken place in capturing enhanced images and their processing for use in the delivery of 3D, HDTV and UltraHDTV, and participants were reminded that content Quality Assurance (QA) was needed to ensure viewers comfort and protect business revenue generated from advertisements. Traditional Quality of Service (QOS) focused on measurement of technical parameters such sync byte error and bitrate but participants were told viewers were not bothered by these technicalities and that Quality of Experience (QOE) provided a better QA method as it measures parameters more likely to generate viewer complaints and changing channels.
The next session heard there had been a rapid transition from traditional multimedia platforms to more versatile platforms such as Hybrid
TV, Broadband, Smart Applications as well as the use of cloud technology. This added a new dimension to the enhanced access that the audiences have to multimedia content.
One of the highlights of the session on Assimilating Effective Workflows and Media Management was a presentation by Turkish Radio Television (TRT) of their experience in setting up a digital archive system. The Korean broadcaster KBS related how it had made the transition to File Based Production Systems by using input from staff, re-using old systems and preparing for stable operation.
The workshop on Content Creation for HDTV heard of growing demand for high definition programming, but it came at a cost: HD brings out fine detail necessitating extra time and effort during makeup, set design and costume maintenance. While the benefits of HD were amazing pictures and longer shelf life, two major downsides were the difficulty of working with mixed SD/HD formats and reduced revenue for SD content.
The sixth session looked at the different approaches that have been developed
for terrestrial and satellite delivery of UHDTV as well as mobile multimedia, and the closing session on Day Three focused on progress and lessons learned about digital radio.
The final day of the symposium started with a session sponsored by the Malaysian Communications and Multimedia Commission on Setting up Infrastructure in Emerging and Developed Markets. Participants were reminded that it was important to plan and optimise infrastructure as it was the major cost issue in setting up a new network. Therefore, careful frequency and coverage planning, optimal selection of transmission parameters and radiated power were required.
The final session of the symposium presented success stories and challenges faced by broadcasters and the industry in digital implementations. Participants were told that broadcasters have many reasons to think green, not just to be environmentally friendly but to reduce operating costs, ranging all the way from optimising power using Modulation Dependent Carrier Level (MDCL) techniques to using LED tower lights and strobe lighting.
