Service lists

A guide to how to discover and navigate television and video services in an online world using simple lists of channels and services.

The importance of lists

Television has been organised around lists of channels for decades. You could turn on the television, move up and down through a familiar channel lineup, or enter a channel number, and quickly choose what to watch. As television and video continue to move online, that simple experience has become more complicated.

Today, channels can come from both broadcast television and streaming services. Programmes are no longer limited to a fixed linear schedule, but can be watched whenever you want. The range of programmes available has risen dramatically, from traditional national broadcasters to global media services.

With that expansion of choice, it has become harder to find what to watch and to move easily between different channels and apps.

So are lists still relevant in an online world, and how can they simplify the viewing experience?

What is a channel list?

A channel list is simply an ordered way of organising television and video services so people can easily browse and choose what to watch.

Traditionally, this meant broadcast channels delivered over the air, on cable, or by satellite. These channel lists were typically provided as part of the television service. They were familiar to viewers, easy to navigate, and popular channels could be selected directly by their memorable number.

Channel lists can now include traditional broadcast channels and services delivered over the internet. As well as channels from national and international broadcasters, they can include hundreds of online channels based on a specific theme or even a single series of programmes. Channel lists can also link directly to apps, providing a simple way to access an entire service catalogue.

In an online world, these different types of channels can all sit alongside each other. They are no longer tied to a single type of service.

Why do we need channel lists?

Lists are a simple, useful, and familiar way of organising information.

We use lists every day, whether it is things to do, what to buy, or places to visit. Lists help us make sense of choice by putting things in an order. They can reflect priority, importance, or popularity, and they act as a form of memory, helping us remember things by their position in a list. They make it easier to scan, compare, and choose from a range of possibilities.

A numerically ordered list provides a particularly efficient way of selecting something. Combined with memorable images such as logos, lists become an intuitive way to recognise and select what we are looking for.

Lists provide a simple, structured way to navigate a wide range of services, even when the number of choices is large. In many cases, lists replace searching with choosing, allowing something to be picked directly from a visible set of options.

Ordered lists are easy to navigate using a television remote control, keyboard, or touch screen. That is why lists work so well for visual interfaces, whether presented as rows or columns, or as lists of lists.

Just as television services have long used channel lists, online video services also use lists to present viewing options. Lists remain a natural and effective way to combine the best of television and online video, bringing clarity and simplicity to an expanding world of choice.

How do you find channel lists online?

Channel lists are found in different ways, depending on the television platform or service being used.

Channel lists have been provided as part of a broadcast service. The information needed to organise and present those lists was delivered as part of the digital television signal.

In an online world, there can be many different sources of channel lists. Televisions may provide their own lists of online channels, often with a separate programme guide. Broadcasters offer their own apps, alongside apps from global streaming services, each with their own way of presenting programmes.

Lists of available viewing options are spread across different services and user interfaces. There is no single source, and no single list where everything can be found. This means viewers do not see one complete list of available channels, but a series of partial views, each reflecting a different service or platform.

This fragmentation makes it harder for viewers to find what to watch. It also makes it harder for broadcasters and programme providers to reach their audiences.

To bring back the simplicity of channel lists, they need to be found and brought together across different services, so they can be presented as a single, coherent experience.

How can channel lists simplify viewing?

To simplify viewing, lists of channels, services, and programmes need to be easy to find, consistent in structure, and capable of being combined across different services.

Instead of being tied to a single platform or hidden inside individual apps, these lists need to be available online in a way that televisions can discover and use. This allows lists from different broadcasters and media providers to be brought together into a single, coherent view.

Lists also need to be easy to locate. Just as a search engine helps people find information on the web, televisions need a way to find available lists from different sources.

For this to work, lists need to follow a common structure so they can be understood in the same way, regardless of where they come from. This makes it possible to combine broadcast channels and online channels into a single, unified list.

By making lists discoverable and compatible, it becomes possible to present a complete and organised set of viewing options in one place. This restores the simplicity of a single channel list, while supporting the full range of modern television services.

What is a service list?

A service list is like a channel list, but more flexible and comprehensive. It has many of the familiar properties of a channel list, such as the name of a service, a logo, and often a number. This means it can still be presented and navigated in a way that feels familiar to viewers.

Unlike traditional channel lists, a service list can include services delivered in different ways. It can reference broadcast channels, online channels, and even applications, bringing them together into a single service list.

Service lists are defined in a standardised format, so they can be used across different types of screen, including televisions, tablets, and mobile devices. They are not tied to a single service provider, platform, or manufacturer.

A service list can be provided by a broadcaster, a platform operator, or a national organisation. It can include national services, with appropriate prominence, as well as international services that are available online.

At its simplest, a service list is a structured set of references to where services and applications can be accessed.

How do televisions find service lists?

Service lists are published online by different types of organisation, including broadcasters, platform operators, and national bodies.

For televisions to use these lists, they need a way to locate them. They need to know where to look, and they need to be able to trust what they find.

This is not simply a matter of searching. Televisions need a reliable way to discover available service lists, understand what they contain, and decide which ones to use.

To work effectively, service discovery needs to operate consistently across different services, platforms, and countries, so that televisions can find relevant service lists wherever they are available.

This makes it possible for service lists to be discovered and used at scale, supporting a wide range of television services while maintaining a simple and familiar viewing experience.

What is a service list registry?

A service list registry provides a way for televisions to discover service lists. It acts as a directory of available service lists, allowing televisions to find out what lists exist, where they are located, and what they contain.

Instead of relying on individual platforms or apps to define their own view of available services, a registry provides a shared way to locate service lists from different sources.

A service list registry can include lists provided by broadcasters, platform operators, and national organisations. This makes it possible to discover a wide range of services, from national channels to international online offerings.

In many ways, a service list registry works like an index or a search system for television services. It does not contain the programmes themselves, but helps televisions find the lists that organise and present them.

By providing a consistent way to discover service lists, a registry makes it possible to bring together services from different providers into a single, coherent viewing experience.

Conclusion

Television is moving towards a more open and connected environment, where services are delivered in different ways but need to be presented together. Lists remain a simple and powerful way to organise that choice.

The Service List Registry provides a foundation for this, enabling service lists to be discovered and combined across different services. It supports the future of television and the shift to online delivery, while helping to ensure that viewers can easily find and choose what to watch.
