“…Background pictures, graphics and on-screen text and logos are all elements that were identified as problematic, and are all items that could be broadcast as media objects in an object-based media broadcast. BBC research has developed example personalisation for weather graphics that could be personalised by the viewer (Leonard, 2015), radio that can adapt the level of content detail based on listener preferences (BBC, 2015), and have proposed tools and workflows for scalable object-based media production (Cox et al, 2017). It seems likely that such methods could be used to personalise broadcast media for people with dementia, particularly in the case of augmented elements such as graphics and on-screen text.…”

Purpose The purpose of this paper is to understand factors that affect viewing of television news programmes by people living with dementia, and to identify dementia-friendly design principles for television news programmes and factors for personalising object-based media broadcast. Design/methodology/approach Extensive public involvement comprising two discussion groups with people with dementia and family carers informed the study design and provided supplementary secondary data. Primary data collection comprised a focus group interview with people with dementia (n=4) and family carers (n=4). Past viewing experiences and perceived barriers and facilitators to viewing television were explored. Participants commented on an array of video clips comprising varying segments of fictional news programmes, plus control versions of each segment. Findings Four themes were identified: content (general comments, context, type of media and pace); presenter (body language, clothing and accent); background (location and studio appearance); and technical aspects (graphics, sound, colours, camera, transitions, general issues). Research limitations/implications Limitations included a modest sample size which is offset by exemplary public involvement in informing the study design. Practical implications Measures ensured research involvement and participation was made accessible to people living with dementia. Social implications Participants benefited from sharing views with peers and expressed enhanced wellbeing from knowing their participation could lead to improved television viewing, an important social occupation, for people with dementia in the future. Originality/value This study is the first to be published which focusses on dementia-friendly television news programmes.

“…Sixteen projects meeting this criteria were identified. Two additional projects were initially identified and later excluded as they did not specifically describe audio personalization [59,60]. The majority of projects addressed speech to noise ratio (15 projects).…”

“…Implementation of any OBA personalization may have substantial implications for production workflows and for production costs [134]. The BBC's Responsive Radio experiment, which created an object-based variable length radio documentary, took considerable resources to create [135], though efforts are underway to develop tools that move the process into a scalable workflow [59]. In addition to much-needed tool development, interactions between different dimensions of personalization, and between personalization and other access services, are currently undetermined.…”

Hearing loss is widespread and significantly impacts an individual's ability to engage with broadcast media. Access can be improved through new object-based audio personalization methods. Utilizing the literature on hearing loss and intelligibility this paper develops three dimensions that are evidenced to improve intelligibility: spatial separation, speech to noise ratio, and redundancy. These can be personalized, individually or concurrently, using object-based audio. A systematic review of all work in object-based audio personalization is then undertaken. These dimensions are utilized to evaluate each project's approach to personalization, identifying successful approaches, commercial challenges, and the next steps required to ensure continuing improvements to broadcast audio for hard of hearing individuals.

“…A dependency graph between objects allows for dynamically altering the length of a piece of content while retaining the narrative, and layering allows customised rendering for particular clients. Adoption of OBM has been limited by a more complex production phase, and work is being done to address this [9]. OBM does not however provide focus tracks as such, making it necessary for multiple assets to be provided in order to for example alter the aspect ratio of video without risking losing important parts of the picture.…”

Media is to a large extent consumed on devices that have non-standard aspect ratios, both physically or while rendering content. For example, social media platforms, televisions, tablets, and android devices, most commonly utilise varying aspect ratios of 1, 16:9, 4:3/3:4, 16:9/9:16, respectively. Web pages tend to use responsive design and can therefore have almost any aspect ratio. As current solutions are static, multiple encoded versions of the content must be created to cater for different aspect ratios, increasing workload, storage space requirements and content management complexity. With this in mind, there is a case for client side dynamic aspect ratios that adapt suitably to the user's device to improve their viewing experience based on a common encoded version of the content. In this paper we make the case for a client side dynamic aspect ratio solution, present work on implementation and experimentation, and finally provide some insights into how such a system could be implemented and provided in real world systems. Our solution was tested on content provided by NRK, including both drama series and TV debates.
