Placeshifting Technology



In this postwe will see 1. What is Placeshifting? 2. What is difference between Placeshifting and Timeshifting technologies? 3. Various players in this market and their offerings.

Placeshifting technology

In late 80s VCR brought the technology to watch your favorite program TV whenever you want to. It is basically a timeshifting technology. In contrast Placeshifting technology enables you to watch TV wherever you want to. It allows anyone with a broadband Internet connection to forward video streams from any source (your home television set, DVR , DVD player or home security camera) for remote viewing on a computer, tablet, or mobile phone at any location using high-speed Internet. Placeshifting can be done at home, between rooms using Home network.

Placeshift content can be of live TV or from DVRs. The desire to view sports events live anywhere created the demand for Placeshifting products. Customers see a value, flexibility, and ease of use.

The important players in this field are Sling Media, Mansoon Multi media (http://www.myvulkano.com/) and Sony Location Free. We will see products from Sling Media in details.

Time Shifting Technology

About 3 years back with the introduction of Tata Sky+, we began to hear about timeshifting technology and a new category of products called digital video recorders (DVRs) or PVRs or personal video recorders came into Indian market. Other DTH providers followed soon. The PVR allowed users to record a program and watch it later, at a more convenient time. Consumers could record programs using their VCR, but the DVR automated the process and added more features and capabilities like pause, replay etc on live programs. Since Placeshifting source can be a DVR or PVR it can be considered as superset which encompasses timeshifting too.

Types of Placeshifting technology

Consumer devices using IP can provide palceshifting functionality from any video source and can be standalone products, ex: sling box from Sling media . Placeshifting technology can be built into the PVR itself ex: DishNetwork Sling Loaded. Another way is to run a placeshifting apps in a PC or a MAC to stream media to a remote laptop or a phone. Ex: MythTV, Orb Networks, Sugar sync, etc. These software applications work similarly to remote desktop software like pcAnywhere, providing the ability to view and control devices (and specifically media stored on those devices) remotely.
