A proposal for second screen DTV and remote control application

Usage of handheld devices such as tablets and smartphones as the second screen devices in television is becoming more popular. The main reason for that is great improvement and development of those handheld devices as well as television popularity. In this paper, the system architecture and framework of the second screen features are presented. The paper focuses on implementation of mosaic content list as well as other digital television services such as Electronic Program Guide, Teletext, Personal Video Recording control or live TV on the second screen.

Remote control android application for second screen DTV environment

Living room is a shared space, in which families carry out their daily routines. The proliferation of personal devices (handhelds or laptops) has modified traditional family behaviors including watching television. Great improvement of hardware performance for handheld devices such as tablets and smartphones is the main reason of their increased usage as a second screen device and their newly acquired popularity with digital TV vendors. In this paper, one proposal of system architecture and SW framework for a second screen concept is presented. The paper focuses on implementation of DVB multimedia second screen broadcasting, providing live TV and mosaic content as well as other digital television services such as: EPG, teletext, subtitles, PVR, and remote controller for the TV or STB on the second screen.

Second screen user experience: A new digital television frontier

Availability and increased hardware performance of handheld devices with high resolution screens encourage users to exploit them as the second screen while watching television. Second screen is a term that refers to an additional screen of a handheld device such as a tablet or a smart phone, with an operating system capable of running desired installed applications. Desire to make additional DTV information available to the user which can be presented on the second screen tends to push the limit of digital television in that direction. This paper presents a framework to distribute and present both premium and free-to-air television content. The framework is based on server/client architecture and includes: TV remote control, streaming of television services, additional content (Electronic Program Guide, reminders...), data protection of streamed services to client devices. The system architecture consists of a media server and its clients. Media server is a Set-Top box with Android OS. Main duty of media server is to receive and process DTV content received from broadcasters and distribute the content to clients (second screen devices). Client application is developed on various OS/Platforms: Android and iOS. Multimedia content can be streamed using supported protocols: HTTP, RTP/RTSP, and adaptive streaming protocols (HLS and MPEG-DASH). Streamed content is protected using DTCP-IP. The main objective of the paper is to describe the utilization of before mentioned standards in a framework to use the DTV data and functions beyond the scope of the main TV screen. The client application also implements the remote controller GUI in order to use one device to control the TV.

EPG data control optimization for DTV Set-Top Box

This paper presents optimized EPG data control on DTV Set-Top Box. Optimization is reflected in lesser memory consumption by the data and lesser time consumption in data control. This leads to faster access to the desired information and its presentation to the end user.

Software upgrade of multi-streaming feature in Common Interface plus V1.4

The paper specifies software upgrade of the multi-streaming feature in CI+ V1.4 (Common Interface plus) as an innovative extension to the CI+ V1.3 specification, which is the industry standard for access to protected TV channels in set-top-box devices. The purpose of this paper is to introduce software upgrade of the resources in previous version of CI+ V1.3 with the multi-streaming functionality of some resources in the new version of CI+ V1.4, in a simple manner in order to enhance capabilities of the previous version of CI+.

One solution of EPG data propagation on digital television set-top box

This paper presents one solution of EPG (Electronic Program Guide) data propagation in DTV set-top box. Propagation is based on a existing solution and extensive process optimization has been done. Optimization reflects in lesser memory consumption and in lesser time consumption in propagating EPG data in contrary to the original state. The result is faster access to the requested data and faster presentation of the data to the end user on the television screen.

A proposal for secured streaming of premium content in second screen environment

With the recent popularization of second screen concept, new security issues in home networks have emerged. In this paper an overview of three different approaches to solving these issues will be presented. Moreover, flaws and advantages of each concept are highlighted, leading to final proposal for secured content sharing with second screen clients.

Integration of RVU remote user interface and DLNA remote media player in Qt framework

This paper describes integration of RVU remote user interface and DLNA media player plug-ins in Qt framework. Usage of RVU concept introduces possibility to achieve same user experience across various platforms such as Android, iOS, Linux, etc. Integration of RVU concept into Qt framework enables execution of Qt applications in home network environment. Qt application is stored and executed on the server, while user interface rendering and A/V content reproduction is done on the RVU client side.
