Live TV in Digital Signage
In this article we are going to cover the deployment of Live TV content in digital signage. One of the main reasons for creating zones in digital signage is to enable multiple messages from different sources on the same screen. Basically any video input source can to be displayed on the screen with surrounding advertisements or any type of content. The main advantage of using live feed is to entertain your audience with live video content and at the same time engaging this very audience with advertising or other information. There are several ways to integrate Live TV to your digital signage display. We will cover some of the options while pointing the pros and cons of each technology.
Inputs and Outputs:
When choosing a video capture device for your player it’s important to consider the inputs you have to integrate with. Most video cameras, DVDs and live feed devices come with an Analog Composite connector or HDMI out. If you want to capture video from these devices, you’ll want to make sure your capture device supports your live feed out connector. If you want to use a CCTV camera or analog signal with your video capture device, you will more than likely need RCA A/V inputs.
There are some factors to consider when choosing a USB capture card for your digital signage. With prices ranging from only $30 to up to over $150, making the decision doesn’t have to be difficult or costly. We’ll attempt to help you choose the device that’s right for you.
USB Capture Card:
A USB TV and Video Capture Device is a device that is capable of transferring an analog audio and video signal from DVD, cable TV or satellite to your digital signage screen. The USB TV Capture Device inputs the video signal by either Composite, S-Video or RF inputs. The signal from the USB Capture Device is output to the player by a USB 2.0 connection. The USB TV capture card can support Analog signal in NTSC format with Max Resolution of 720x480 at 30FPS and PAL Video Capture: 720x576 at 25FPS. UCView’s digital signage software, bundled with the USB TV Capture device, captures a signal and plays it in the appropriate zone or in full screen.

Streaming HD and SD Feeds:
Steaming technology has become a main stream content distribution in the last couple of years, allowing you to broadcast HD content through WAN / LAN networks. This technology allows you to utilize it in digital signage by broadcasting the live feed signal to your digital signage players. Streaming media is a multimedia that is constantly received by and presented to the digital signage player while being delivered by a streaming server or streaming device. The distinction is usually applied to media that is distributed over telecommunication networks.
This type of content distribution is a great solution to broadcast live feed in an intranet environment like universities or corporate communications. Your digital signage screen can be fed on demand content from one or multiple streaming feed devices.
