Tech insights

Direct-To-Home (DTH) uses some advanced technologies to deliver entertainment to your home directly. Learning about all these technologies is quite daunting. Consequently, most people dread it and happy to treat it as a black-box. However, thanks to advanced technologies and equipment, you don't have to be an expert in setting this up. Hope this guide will help you understand it better and fix small problems on your own rather than depend on call-center executives of your provider. Also, Media reporters use DVB-S technology to stream LIVE feeds to media houses where the feed is recorded and packaged as a TV program. This means one can watch the Live event sans commercials using a STB if it's unencrypted!! Signals, satellites and encryption Initially, TV transmission was Analog . Hence ALL the TVs have built-in analog tuners. However, analog transmission has limited bandwidth which is not sufficient to transmit ever increasing number of channels. This paved the way for Di

Mi Red 2 Prime is an excellent phone with 2 GB RAM and 1.2 GHz quad-core processor. Xiaomi is leaving no stone unturned to make it a smooth experience both in terms of UI and ease of upgrade via upgrade app. However, if you want a feel of stock Android Marshmallow using standard Android upgrade process, this post will help you. It assumes you have a Linux computer. Note: Take a backup of your data before you start. Recovery, android ROM and google apps packages can be downloaded from internet.

If you are setting up a Linux based media center PC, sooner or later you would stumble upon a remote which is not completely supported out-of-the-box. More so, if you have an RF remote like me. I spent couple of days scanning through multiple posts to figure it out. This post outlines the steps to get your remote working as you'd like. Most remotes are Infra-red (IR) devices. However, radio-frequency (RF) remotes allow you flexibility and better control as line of sight is not mandatory. I have an RF remote that came with ATI TV Wonder HD 250. ATI Theater remote (source: http://tv.manualsonline.com/manuals/mfg/amd/ati_theater.html?p=11) Good news is that most of the buttons work out-of-the-box, i.e. the Linux kernel recognizes the device. However, it was annoying that some single key functions like TV or radio were not working. There are total nine buttons that don't work. The first step is to figure out the scancodes of these keys. Run evtest  as root and press the d

While channel surfing is the favorite pastime of couch-potatoes, I prefer watching selective programs; that too with some summary of the program playing. An Electronic Program Guide (EPG) aids in this purpose. This was also the reason why I decided to move to Direct-to-Home (DTH) from analog TV almost a decade back. So when I embarked on the journey of TV on computer , this was the obvious next step. XMLTV is the most widely used standard for EPG information. However, there are no grabbers for India. So I added my own which retrieves information from Indiatimes website . To install, use following commands. % git clone https://github.com/atamariya/xmltv.git % cd xmltv % perl Makefile.PL % make % make install Once installed, you can configure the channels for which you want to retrieve information by running % tv_grab_in --configure Then you can run the command without any arguments whenever you need the information.
