How does h264 compression work?

H. 264 is an industry standard for video compression, the process of converting digital video into a format that takes up less capacity when it is stored or transmitted. An encoder converts video into a compressed format and a decoder converts compressed video back into an uncompressed format.

What is H 264 AVC format?

Also known as MPEG-4 Part 10 or Advanced Video Coding (MPEG-4 AVC), H. 264 is defined as a block-oriented, compensation-based video compression standard that defines multiple profiles (tools) and levels (max bitrates and resolutions). This format supports 4K and up to 8K Ultra High-Definition.

What is h264 level?

H. 264 levels specify the maximum data rate and video resolution that a device can play back. For example, Apple’s iPad 2 specifications indicate that the device can play video encoded using the Main Profile, Level 3.1.

Is H 264 better than h265?

265 codec, also referred to as High-Efficiency Video Coding (HEVC), is the worthy successor to H. 264. 264, this newer standard offers from 25% to 50% better data compression at the same level of video quality. It basically delivers high-quality videos at the same bitrate.

What are the two types of divergent boundaries?

There are two types of divergent boundaries, categorized by where they occur: continental rift zones and mid-ocean ridges. Continental rift zones occur in weak spots in the continental lithospheric plate.

Are there any divergent boundaries in East Africa?

Divergence is also going on in the Great Rift Valley of East Africa, forming the boundary between the Somalian and Nubian plates. But these rift zones, like the Red Sea, have not opened much even though they are millions of years old. Apparently, the tectonic forces around Africa are pushing on the continent’s edges.

When does an eruption occur at the divergent boundary?

Divergent boundary. Each eruption occurs in only a part of the plate boundary at any one time, but when it does occur, it fills in the opening gap as the two opposing plates move away from each other.

How is the Mid Atlantic Ridge a divergent boundary?

The mid-Atlantic ridge lies beneath the Atlantic Ocean and separates the North and South American plates from the European and African plates. This divergent plate boundary moves apart at a rate of ~2.5 cm per year, relatively slow for a divergent plate boundary, and rises ~2-3 km above the ocean floor.
