A 1974 study by Katz, Blumler, and Gurevitch stated five basic assumptions for a framework for understanding the correlation between media and audiences. These assumptions are: [17] The audience is conceived as active. In the mass communication process, much initiative in linking gratification and media choice lies with the audience member.
This is a listing of open-source codecs—that is, open-source software implementations of audio or video coding formats, audio codecs and video codecs respectively. Many of the codecs listed implement media formats that are restricted by patents and are hence not open formats.
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
Media psychology is a branch of psychology that focuses on the interactions between human behavior, media, and technology.Media psychology is not limited to mass media or media content; it includes all forms of mediated communication and media technology-related behaviors, such as the use, design, impact, and sharing behaviors.

Three types of pictures (or frames) are used in video compression: I, P, and B frames.. An I‑frame (intra-coded picture) is a complete image, like a JPG or BMP image file.. A P‑frame (Predicted picture) holds only the changes in the image from a previous frame.
VP8 is a traditional block-based transform coding format. It has much in common with H.264, e.g. some prediction modes. [8] At the time of first presentation of VP8, according to On2 the in-loop filter [9] and the Golden Frames [10] were among the novelties of this iteration.
