High Definition Video Viewer So, are you ready to join the blessings of civilization and enjoy viewing your favorite (or new) movie in the standard HD (High Definition Video). For the full HD video requires the perception of a bunch of three components - the receiver, source content. Let's start from the end) of video standard HD - the media file with a resolution of 720p (1280x720) - HD Ready, or 1080p / i (1920x1080) - Full HD. Containers that are usually put video and audio tracks standard HD - mkv, ts, m2ts. Container (Mediakonteyner) (not to be confused with codec!) - a file format (extension) of a multimedia file containing video, audio and other flows, as well as metadata. Flows themselves contained in the container, remain unchanged (similar to conventional archives. RAR, etc.). Can extract video / audio tracks and subtitles, and then put them into another container, or even convert to reproduce separately. If you need to disassemble or repack the container, ie, Change the file format, you will need special programs such as MKVToolnix to mkv or ts or tsMuxeR for m2ts. Container *. mkv (aka matroska / doll /) - the most popular multimedia container may contain a large number of streams of audio, video and subtitles, allowing you to store a single file and a movie reproduce its multimedia player. Containers ts, m2ts (transport stream / transport stream /) - 'commercial' container: *. ts designed for streaming media (IPTV, DVB) and better perceived stationary equipment; *. m2ts is designed to read from the file system (with media). This is a standard container for Blu-ray video and it can be activated provided for Blu-ray video and audio formats and subtitles in a graphic format PGS. Video Codec - Program / compression algorithm video (ie, reduce the size of the video...

Education System Problem solving is an activity composed of several different processes, and in this sense, is a means by which individuals use previously acquired knowledge, declarative or procedural, in order to meet the demands of a new situation. In education, we must solve problems where it attaches great importance to the correct solution, however, it is necessary to modify this concept and ensure that teachers accept the notion that the primary objective in teaching is to help solve problems students to develop thinking skills and processes that allow them to achieve correct solutions. Krulik and Rudnick (1982) suggest that the educator must: Create an appropriate environment for the resolution of problems. To provide a wide and varied repertoire of problems that create an intensive and extensive practice, in addition to posing a challenge for learners. Teach students to develop strategies that enable them to read the problems in the form analytical. Call on students to invent their own problems. Allow students to work in pairs or small groups. Promote the students' use of alternative strategies: recognize patterns of problems, work in reverse, to predict and test, simulate, experiment, data reduction, offset, etc. Make questions while students are in the process of discussing the procedures to solve problems. Allow students to check their answers. Using strategies for the development of thought processes. Make representing students, through a flowchart, its own procedures for solving problems. In the area of problem solving have developed several instructional models: direct instruction, self-study and implementation guided or directed learning: The direct instruction has been used more frequently to teach specific strategies for a particular task. Students are taught a specific action sequence and the sequence is modeled within the context of the task. This instruction is structured, step by step, to secure control of the proceedings before...
