Survey of Catch-up TV and other time-shift services: a comprehensive analysis and taxonomy of linear and nonlinear television

This study analyzes recent changes on the television (TV) market, and the transformation of TV consumption habits, motivated by new transmission and recording technologies. Through an international survey spanning 62 countries and 4 continents, a growing presence of nonlinear TV services and over-the-top (OTT) content offerings is found. A detailed taxonomy of ways of watching TV content on the TV set is proposed to clarify the existing Pay-TV and OTT services, including time-shift and videoon-demand (VoD) terms such as Pause TV, Start-over TV, personal video recorder, Catch-up TV, transaction VoD, and subscription VoD, to name a few. An in-depth literature review is conducted, focusing not only on the technological aspects of nonlinear TV, but also on its business and consumer behavior impacts. The existing research works clearly demonstrate a lack of global reach by mostly concentrating their analyses on specific regions or countries. In addition to the literature review, the survey and taxonomy definition, the impact of nonlinear TV on the complete supply chain is also extensively discussed, indicating structural changes not yet addressed in the current literature.

“…O maior consumo de vídeos online acontece nos primeiros três dias, com 58% da audiência. Resultados semelhantes foram obtidos por investigadores italianos (Nencioni et al, 2013), que acrescentam que os utilizadores preferem conteúdos em série, de curta duração, com 30 ou 60 minutos, e que têm um gosto para certos géneros específicos, como comédia, drama e programação infantil.…”

Este artigo discute as mudanças em curso na televisão, acentuadas pelo aumento da oferta de conteúdos fornecidos on-demand. Tais conteúdos são disponibilizados, principalmente, por operadores de TV por assinatura, possibilitando uma experiência de TV não linear. Para caracterizar o cenário internacional da oferta de conteúdos de TV não linear, realizou-se uma pesquisa em 62 países que permitiu catalogar as diversas tipologias de serviços oferecidos. Complementarmente, foi feita uma revisão detalhada da literatura referente ao tema que evidenciou a inexistência de levantamentos similares. Desta forma, podese constatar a crescente oferta de serviços de TV não linear, comportando dois efeitos: 1. uma migração da audiência televisiva para estes serviços, com mudanças estruturais, ainda que incipientes, na organização dos programas e das narrativas; 2. um fortalecimento da televisão em direto (ao vivo) na TV tradicional, linear. Neste enquadramento, o presente artigo fornece bases empíricas para análises teóricas aprofundadas, discutindo um tema ainda incipiente nas ciências da comunicação e áreas correlacionadas.Palavras chave: Catch-up TV, grelha de programação, vídeo on-demand, TV em direto. AbstractThis article discusses the changes taking place on television, accentuated by the increased supply of ondemand content. Such content is made available primarily by pay-TV providers, allowing a non-linear TV experience. To frame the international scene offering non-linear TV content, a survey was conducted in 62 countries, where the offered services were catalogued. In addition, a detailed review of the relevant literature was made, being possible to realize the lack of similar surveys. In this scope, one can note the growing supply of non-linear TV services, with two effects: 1. a migration of the audience to these services, with structural changes, even if incipient, in the organization of programs and narratives; 2. A reinforcement of live television in the traditional linear TV. The present article provides an empirical basis for in-depth theoretical analysis, discussing a still incipient topic in communication sciences and related areas.Keywords: Catch-up TV, programming schedule, video on-demand, live TV. IntroduçãoA televisão tem sido objeto de estudo em inúmeras áreas. Cientistas e investigadores têm-se dedicado a estudar a televisão em áreas como a produção de conteúdos, tecnologias de transmissão e recepção, a forma como as pessoas consomem o conteúdo, o impacto da programação na sociedade, formas de publicidade, modelos de negócio, opinião pública, psicologia, sociologia, entre outras.Uma área que, de forma direta ou indireta afeta todas as restantes, centra-se no desenvolvimento e na introdução de novas tecnologias, especialmente do lado do cliente. É amplamente reconhecido que as novas tecnologias afetam especialmente o consumo e o modelo de negócios. Por exemplo, o surgimento dos

Abstract-Traffic from wireless and mobile devices is expected to soon exceed traffic from fixed devices. Understanding the behaviour of users on mobile devices is important in order to improve the offered services and the provision of the underlying network. Globally, more than 60% of consumer Internet traffic is estimated to be video traffic, and the most popular video website, YouTube, estimates that mobile access makes up nearly 40% of the global watch time. This paper presents the first work to study the characteristics of YouTube user requests on a nationwide cellular network. This study is based on the analysis of a large dataset generated by 3 million users and collected by a major telecom operator. We show for instance that 20% of the users generate 78% of the requests, and that over 80% of the requests target only 20% of the distinct videos accessed during the data collection period. Our results provide a comprehensive insight into the way people use YouTube on mobile devices, and show a very high potential for video cacheability on the cellular network.
