Internet Protocol TV

Explore the development of a proof-of-concept for a standardized set-top box compatible with various service providers to display internet media streams on a standard TV without a PC. The project aims to stream real-time Real Media files from remote servers, convert them to MPEG4 format, and play the resulting audio/video via an LCD screen. The system uses a TI DaVinci SoC, MPlayer for media playback, and MEncoder for transcoding. Challenges include integrating different media formats and optimizing processing efficiency. Future developments include GUI development, commercialization, and algorithmic enhancements for better performance.

  1. Internet Protocol TV Next Generation Set-Top Box Proof-of-Concept Hugo Kwok David Shen Jimmy Jeong Allen Lai Group 10

  2. Agenda • Background • Objective • System Overview • Challenges • Future Developments • Conclusion • Demo • Questions?

  3. Background • Currently, the TV market is dominated by cable and satellite providers • IPTV is a new technology where users are able to view TV contents over the internet. • IPTV is already available in certain cities • (e.g. TELUS, AT&T)

  4. Background (continued) • Two segments • Live broadcasts • Stored broadcasts or Video On Demand (VOD) • Users stream contents after they are downloaded (e.g. to a hard drive) • Can be easily integrated into the household • Internet connection

  5. IPTV – Graphical Representation

  6. Objective • Standardized set top box compatible for multiple service providers • Display internet media streams on a standard television set with-out using a PC • Proof-of-concept to commercialization

  7. Proof of Concept • Stream real time Real Media file from a remote server on the Internet via RTSP • Convert Real Media file through decode/encode algorithms into MPEG4 format • Play resulting audio/video with Media Player (MPlayer) on a Linux development platform via an attached LCD screen on the development board

  8. Equipment • TI DaVinci System-on-Chip • Dual-core with ARM9 and C6000 DSP CPU • LCD screen output • Internet connection • Helix Server • Simulates online media streaming from a local directory

  9. System Flow Diagram

  10. Why MPEG4? • The set-top box shall stream various media format and convert it into MPEG4 video and MP2 audio format for storage and display due to the following reasons • Easy to manage • High compression ratio • Further software development focused on MPEG4 format media file

  11. Why MPlayer? • Physical media • CDs, DVDs, Video CDs • Container formats • 3gp, AVI, ASF, FLV, Matroska, MOV (QuickTime), MP4, NUT, Ogg, OGM, RealMedia • Video codecs • Cinepak, DV, H.263, H.264/MPEG-4 AVC, HuffYUV, Indeo, MJPEG, MPEG-1, MPEG-2, MPEG-4 Part 2, RealVideo, Sorenson, Theora, WMV • Audio codecs • AAC, AC3, ALAC, AMR, FLAC, MP3, RealAudio, Shorten, Speex, Vorbis, WMA

  12. Large selection of supported media formats Open source software MPlayer (continued)

  13. MEncoder • Transcoder with MPlayer bundle • Converts wide range of multimedia files to a specific file format • Able to save a video and audio stream separately onto a memory location for post processing

  14. In the proof of concept device, the real media video will be developed such that the set-top box can stream media content in RM format Codec developed based on the source code of RV30 from the Helix Community MEncoder (continued)

  15. Transcoding – High Level

  16. Transcoding – Conversion Block

  17. Problems Encountered • Setting up development platform and OS • Researching and understanding the technical backgrounds • Understanding source code • Obtaining Real Media Source Code • Not open source like other codecs (only binary files available) • Requires license from Helix Community • Not successful in compiling

  18. Problems Encountered • Cross-compiling RealPlayer source code for the ARM • Attempted to understand header files of codecs suggested by Dr. Bajic • Tried different binary files of real video codecs • RealMedia codec in binary form for Palm, which ran on ARM processor • Extracted files were not compatible

  19. Implement streaming of all other input media formats, convert and output to one universal format e.g. Windows Media, VLC, etc.  MPEG 4 Migrating system from ARM CPU to C6000 Digital Signal Processing CPU for more efficient processing and algorithmic calculations Developing a GUI Integrate proof of concept and commercialize it in set top box Future Developments
