| Overview |
| OGV is a free and an open container format for digital media(Audio, Video and text). It is unpatented software and can be used by users free of cost. It compresses the files using lossy compression and discards the redundant information which human ear incapable to process. It is used especially for online streaming. Furthermore, this format is also good for data manipulation and it is standardized by OGG Vorbis. This format is a container format used for Audio, Video and metadata files. For compressing of files, it uses Vorbis Compression Technology. The recorded content can be played using different software like VideoLan VLC Media player and Helix player; etc. |
| Technical description |
| An OGV file can have separate unrestricted open-source codecs for varied media types like audio, video, text. Theora and DivX are some examples. It supports variable bit rate and based on Discrete cosine transform (DCT) compression pattern. To compress or encode videos it uses Chroma subsampling (Due to low acuity for colours by humans, it uses less resolution to encode images),block-based motion compensation and an 8-by-8 DCT block. The pixels in it are grouped together in various structures- blocks, super blocks and macroblocks. Videos on the web pages can be played using HTML coding i.e. HTML5< video > tag. Although these files have different source code, yet, the videos in this format are often addressed as OGG files in HTML source code. In addition to this, a DirectShow codec pack is provided by the developers so that this format can be used both as open-source and for commercial applications as well. |

| Overview |
| It is a format for audio files which compresses the audios using lossy compression. It neglects the redundant information which can not be processed by the human ear. Internet Engineering Task Force (IETF) has standardized this format. It has superseded the Vorgis and Speex. It offers low latency i.e. there is a less delay in the signal when it enters the system and when it emerges out, this results in real-time interactive communication like video conferencing. Due to its good audio quality, it is widely used by in various listening tests. |
| Technical description |
| OPUS has good compatibility with low-end embedded processors as it is less complex. Ranging from 6kbps to 510kbps, it can support both variable and constant bitrate coding. Also, the frame size from 2.5ms to 60ms is supported by this codec. It works smoothly and maintains stability (by avoiding the distortion) while mixing of packets from distinct streams. Speech, Hybrid and pure-CELT are the three different methods used for encoding the audios of varied frequencies. For compressing the Speech up to 8kHz, SILk is used which is an audio compression developed by Skype Limited. The next mode, Hybrid uses CELT to compress the audio files above 8kHz frequency or for wider bandwidth and frame sizes 10ms and 20ms are supported by this mode. CELT(Constrained Energy Lapped Transform) is an open and free audio compression format which is especially used in communication that requires low latency. For general audio, the last mode pure-CELT is used. CELT is used for frame sizes which are less than 10ms. |
