OPUS Technical Specifications

File extension	.opus
File category	Audio
Stands for	Ogg OPUS
Developer	Xiph.Org
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 It has superseded the Vorgis and Speex.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.

WMV Technical Specifications

File extension	.wmv
File category	Video
Stands for	Windows Media Video
Developer	Microsoft
Overview	It is a video format based on the Microsoft Advanced systems format(ASF) and it is a sequel of video codecs. There are three varied codecs for this format. Actual WMA compression technique was developed only for internet streaming applications and it gave tough competition to RealVideo. The other compression techniques include WMV screen and WMV image which are designed for specialized content. These files are compatible with both Mac and Personal computers ;etc. This format attracts companies those want to sell audios and videos online due to DRM technology. This is the most popular among its family members. Interlaced videos can also be played using this video extension. There is an advanced version named WMA 9 which automatically comes into play when video resolution exceeds 300,000 pixels and the bitrate 1000 kbit/sec.
Technical description	It is based on DRM(Direct Rights Management), thereby, it restricts users from making unauthorized copies that are often bought online from stores. HD DVD and Blu-ray Disc are formats for physical delivery which were adapted when WMV version was standardized by the SMPTE(Society of Motion picture and Television Engineers). It is now termed as VC-1. MPEG-4 AVC, AVS and MPEG-4 ASP are other competitors against this format. Furthermore, it can also provide support to the variable bit rate, average bit rate and constant bit rate. It enables makers to use non-square pixels as well. Lastly, it can process videos using frame interpolation in which intermediate animation frames are created between the existing frames.
