Abstract

In order to satisfy the individual needs of consumers for recording TV programs in some different ways, an improved scheme is presented to implement Personal Video Recorder (PVR) function in Android set-top box (STB). As for live TV programs, there are three alternative ways which are continuous recording, timer recording and time-shifting recording being designed. As for TV programs in the future, the way of scheduled recording is designed. Namely, monitor task in the background is checked by the updating of Time and Date Table (TDT) in accordance with Electronic Program Guide (EPG) information. The results show that this scheme is effective and feasible, and it enriches the interface function between TV and consumers. DOI : http://dx.doi.org/10.11591/telkomnika.v12i2.3928

Abstract

In order to satisfy the constantly increasing appetite of consumers for content in today’s world, Personal Video Recorder (PVR) function is implemented in digital TV set-top box (STB) based on Android platform. An algorithm that adjusts video Presentation Time Stamp (PTS) based on audio PTS is presented, which aims at the problem that audio is not synchronized with video existing during playback. And a method of generating index file based on the information of I-picture is presented, which aims at the implementation of trick modes. Namely, the location of I-picture which is used to generate index is recorded while audio and video data are being sent to storage medium in Packetized Elementary Streams (PES) format. The test results show that the TV STB designed can implement synchronization of audio and video accurately and reliably and the recorded programs can be played on the STB at different speeds. DOI : http://dx.doi.org/10.11591/telkomnika.v12i1.3231
