Introduction

TME 3 is a written request. The idea of this exercise is to investigate details inside a codec using Theora and Vorbis.

All relevant information you may find in xiph: http://xiph.org/ogg/

Part 1: Vorbis

Your report should contain the following:

  1. A one- to two-page summary of Vorbis.
  2. Technical details including, but not limited to, sample rate, bit rate, compression ratio, support of variable and constant bit rate, brief specification of Vorbis.
  3. A comparison of Vorbis and MP3. You may search the Internet for any comparison reports of listening quality. Note that you should give the comparison of different bit rates.
  4. A list of references
  5. Total length of part 1 should be about 5 pages.

Part 2: Theora

Your report should contain the following:

  1. A one- to two-page summary of Theora.
  2. Technical details including, but not limited to, algorithms used, brief specification of Theora, bitrate and resolution supported, and o/s supported.
  3. A comparison of Theora and MPEG-4. You may search the Internet for any comparison reports of viewing experience or quality of Theora and MPEG-4. Notice that the concept of video quality is very rich, diverse, and extensively studied. It is not the intention of this exercise to present a survey on the concept of video quality to compare Theora and MPEG-4. You only need to give one or two reports that help the reader understand at least one aspect of the viewing differences between the two codecs. Be sure to include in your report the scope and meaning of video quality.
  4. A list of references
  5. Total length of part 2 should be about 5 pages.
