2. THE LIQUID HD PROTOCOLS

Purposely built for consumer electronics networking in the home, Liquid HD

technology consists of an architecture and suite of protocols designed to be easily and

inexpensively incorporated into CE products. Unlike earlier proposals for home networkingthat originated in the PC world, the Liquid HD architecture was designed from the ground up to

be lightweight and low-cost. Liquid HD protocols run on top of industry-standard IP

networking protocols, enabling them to be deployed on coax IP networking like MoCA,

wireless like Wi-Fi , power line like Home Plug or HD-PLC, Ethernet or even next-generation

HDMI which adds a high-speed, bi-directional data channel to the HDMI cable. And since

Liquid HD functionality can be integrated into devices either through silicon or via software, its

implementation is flexible enough to meet both the design needs and cost targets of CE

manufacturers.

Figure 2.1 The Liquid HD Architecture

The Liquid HD suite of protocols includes the following major elements:

Liquid Discover

Liquid Discover is a streamlined, automatic discovery protocol that allows

connected devices to broadcast their capabilities and query each others availability,

simplifying setup and use for consumers. It includes a unique, energy-saving Wake-on-LAN

(WoL) feature, where devices can be put in low-power sleep or standby mode and awakened

remotely when needed.

Liquid Media

Liquid Media is an audio/video (A/V) streaming protocol that enables, robust,

secure distribution of multiple HD compressed streams across the CE network. Liquid Media

leverages standard MPEG transport streams for carrying MPEG-2, h.264 (AVC) and VC-1

compressed media streams.

Liquid Pixels

Liquid Pixels is a powerful protocol for remoting the user interfaces (UIs) of CE

devices and receiving remote control commands from the TV. Its the only CE solution that

allows a source device to project its user interface across the CE network to any display in the

home in a low-latency, low-bandwidth, pixel-accurate manner. A single Liquid HD-certified

remote can now control any device on the Liquid HD network. A tremendous benefit forconsumers, this eliminates the frustration of managing multiple device-specific remotes.

Liquid Control

Liquid Control is the control messaging protocol for Liquid HD networks. Once

devices have discovered each other using Liquid Discover, Liquid Control allows them to set

up media streaming via Liquid Media and manage UI sessions using Liquid Pixels.

Liquid PlayTM

Liquid Play is a comprehensive security architecture that allows consumers to

play content on any of their Liquid HD-certified devices. Liquid Play includes a content

protection architecture, endorsed by Hollywood studios, that meets their requirements for

robustness, revocation, and renewability. In addition to protecting content, Liquid Play also

protects CE devices from network-based attacks, securing all Liquid Discover, Liquid Pixels

and Liquid Control transactions across a Liquid HD network.

3. AN INNOVATIVE APPROACH TO HOME ENTERTAINMENT

Liquid HD technology gives consumers the freedom to enjoy all digital content on their

own terms, whenever and wherever they choose. Source devices are no longer tied to individual

displays, freeing consumers to enjoy their chosen content on their specified display.

With its unique combination of expanded functionality, greater usability, and low

implementation cost, Liquid HD technology offers tremendous benefits to manufacturers and

service operators. From STBs and DVRs to IPTVs, Blu-ray players, game consoles and more

CE manufacturers have a major opportunity to advance their digital product lines and better

differentiate from the competition as the wave of HDTV matures. Liquid HD technology

affords the kind of must have functionality that creates its own demand, simplifies and

streamlines installations, reduces returns and service calls, and generates follow-up sales as

customers expand their Liquid HD networks to include more compliant devices. For service

operators, Liquid HD offers a cost-effective way to bring multi-room and multi-screen services

to their customers, lowering both capital and operating expenses while increasing customer

satisfaction and reducing churn.

Becoming a Liquid HD Adopter

Liquid HD technology enables consumers to quickly and easily link all TV, home theater,

PC, and mobile devices into a feature-rich consumer entertainment network, and unleashes the

freedom to enjoy digital content on any Liquid HD-enabled display, whenever and wherever a

consumer chooses. Powerful, flexible, and easy to use, its the next big step in the evolution of

digital entertainment.

6. WHY WE ARE DIFFERENT

A New Approach to CE Networking

Over the years, many systems have been proposed for the networking of home

entertainment devices, from FireWire-based solutions like HAVI and HANA to DLNA. How is

Liquid HD different from these earlier attempts?

At its core, Liquid HD is a suite of technologies that define how consumer electronics

devices store and share media and communicate with each other. This CE-focused approach

adheres to design principles that yield systems that are simple, low-cost, secure, robust, and

testable in a hardware-intensive fashion. By contrast, previous PC-centric solutions have been

hampered by high cost, excessive complexity, and limited functionality.

Freedom from the PC: Unlike PC-based solutions, Liquid HD embeds functionality in

the TV, freeing users from a host of potential problems and complexities. Under this

approach, the TV evolves from a static receiver into the smart hub and connection point of

the Liquid HD network. Source devices can be likewise embedded with Liquid HD

functionality, or modified with a simple adaptor. In either case, devices will self-discover

and auto-configure when connected to a Liquid HD network, providing true plug-and-play

usability.

Greater flexibility: The Liquid HD architecture embraces the widest possible range of

digital source devices, including home theater components, PCs, gaming consoles, cameras

and camcorders, even mobile phones. Moreover, these devices can be connected to the

Consumer Electronics Network in a wide variety of ways, including coaxial cable, Ethernet

cable, or even Wi-Fi. Users are not limited in what kinds of devices they can access, or

restricted to a particular cable type.

Superior interface: One of the core technologies in the Liquid HD architecture is

LiquidPixels, a powerful set of protocols enabling rich, pixel-accurate, modifiable, remote

user interfaces. To the consumer, this means a consistent, persistent, highly intuitive user


8/9/2019 Liquid HD

experience. And because it can be easily customized and branded, it offers a unique

opportunity for the service operator to boost customer satisfaction and build loyalty.

Digital Rights Management: Liquid HD incorporates a robust security architecture

that enables users to enjoy protected content like Blu-ray Disc movies with the same

convenience and flexibility as their personal content, such as digital photos. Liquid HD

technology uses proven hardware-based security to protect content against unauthorized

copying and sharing while empowering consumers to play their legally obtained content on

any Liquid HD device in the home.

Green technology: Liquid HD takes a unique approach to power management, enabling

devices in a network to go into sleep/standby mode when not being used, and to wake

automatically when requested.

Highest quality: Developed by the same company that led the development of the

HDMI interface, Liquid HD offers a world of new functionality without compromising on

the superior image quality that users have come to expect. It's the next big step in the

evolution of HD technology.
