Why the new H.264-SVC Scalable Video Coding is exciting!
These days, video based applications are on the rise and the Internet is expected to satisfactorily cater to the bandwidth intensive and latency sensitive video content, notwithstanding its shortcomings like packet loss, etc. While we cannot do much about the physical network that makes the Internet, we can sure make video encoding techniques more efficient and effective. If H.264-SVC is standardized to give interoperability and backward compatibility, we might just hit gold!

Why H.264 AVC (MPEG-4 Part 10) Video Codec is critical for Video Transmission
Transmission of video has become an important function that needs to be supported by WAN networks including the Internet. But, if video is handled in its raw form, the bandwidth consumed/ size of video could be huge. Hence video compression through codec’s was introduced. Let’s learn something about one of the most popular video compression technologies – H.264 AVC (MPEG-4 Part 10) in this article. Whether you are handling Video Conferencing systems, IP Video Surveillance systems, HD DVD, HDTV, Online video storage and streaming, video game consoles, mobile video through 3G/4G… you need to be conversant about one important technology that all of them use – H.264 AVC (Advanced Video…
