Is HDMI Over IP Right for Your AV System?
What is HDMI over IP ?
Traditional System Structure VS HDMI over IP:
What's the Difference?
- System Infrastructure
A traditional AV system will require:
- Source: Devices like NVRs, Blu-ray DVD players, PC, and HDMI cameras.
- Transmitter: Processing signal and sending it to the remote end.
- Receiver: Receiving a signal from the local end and sending it to a display.
- Display: Devices like TVs, LCD monitors, and projects for display video sources.
An HDMI over IP system will require:
- Encoder: It can convert an AV source into chunks of digital data called packets and send them through a network.
- Decoder: It can convert packets back to an AV signal and send them to a destination.
- Ethernet Switch/ Network Switch: It can organize Ethernet devices and use packet switching to send packets from one/ multiple sources to different destinations.
Every end-point between an encoder, a decoder, or an Ethernet switch can be 100 meters (300 feet) apart.
Use an encoder, an Ethernet switch, and multiple decoders to distribute an HDMI signal.
Use multiple encoders, an Ethernet switch, and a decoder to switch multiple HDMI signals.
Use multiple encoders and decoders thru an Ethernet switch to route various HDMI signals.
Why use HDMI over IP ?
- Distance: With the use of AV devices such as HDMI extender transmitters and receivers, network switches (which can be “daisy-chained”), and fiber, long distances can be reached.
- Scalability: Adaptability is crucial for any AV system. The need for system changes and improvement is inevitable over time. With HDMI over IP, all you need to upgrade is an additional encoder and decoder.
- Cost-effective: Nowadays, most enterprises have existing network infrastructures. You can easily integrate Ethernet devices into the existing network instead of building a new one. The high scalability of HDMI over IP may also save you some costs shortly from re-cabling and upgrading devices.
- Flexible Controls: Due to the flexibility of Ethernet. Every device within the network can be controlled via not only a keyboard and a mouse but also PC software and a mobile APP. This feature gives users access to intuitively control a large-scale AV system without getting confused by a vast amount of inputs and outputs.
