ezStation : Lecture Capture System

Never miss a single word in class.

Recap of ezStation

• ezStation is a multimedia lecture capture system that helps teachers to have a

completed record of every lecture in class easily.

• ezStation records up to 3 sources of video simultaneously.

a. A video of teacher’s lecture on stage

b. A video of students’ in-class reactions and

behaviors

c. The computer screen of teacher’s instructional

materials and in-class annotations

New function of ezStation• Retains all the functions of ezStation with less hardware

a. One encoder box and ezStation software handles everything

b. Cameras, IWB screen are all connected to the encoder

c. Less bandwidth and equal timing:1 video file instead of 3

• It also gives you more…1. HDMI available for higher video quality

2. LIVE streaming through online platform such as YouTube Live

Process

Two cameras record teacher and

students respectively. These two

signals, as well as the screen capture of

teacher’s materials will be sent to the

ezStation encoder.

A video with

combination of 3-

screen to be produced

automatically and

saved on encoder and

upload private cloud.

Students

then can go

online and

review the

lessons.

Feature summary

• Simple and intuitive control: Start the recording function from HiTeach software.

• No shooting area constraints: A Bluetooth microphone with infrared sensor

allows camera to follow teacher’s movement and capture every moment.

• Tag key concepts: students can use their IRS clickers to mark the parts which they

consider them important or difficult for review purposes

• Automatically print Logo on the video

• The recorded video can be uploaded to private FTP or ezCMS on IES for

management and review without time and space limitations.

Storage and management: ezCMS• Videos recorded by ezStation can automatically be uploaded to and saved on ezCMS

(Content Management System), which is an add-on module of our private cloud service,

called IES (Instruction Expert System).

• Teachers can organize videos

by the content, types of

materials, or privacy, and

assign videos to whole class or

specific students to review.

• When integrated with HiTeach,

the video can be consolidated

with other instructional

materials to create a

completed remediation lesson.
