Pixtree transcoder settings
The second pioneers in the MP4 market appeared on the Korean peninsula. The format, best known as the MP4 extension (although individual manufacturers may use others), is a joint product of local companies Telechips and Pixtree. He appeared in 2004 at the same time as MTV, but technically surpassed the latter by a head.
It was a full blown video. The proprietary Pixtree algorithm based on MPEG4 was used. This allowed for very compact video files, especially for the low resolution displays common at the time. An MP4-compressed song clip was only slightly larger than the same song in a high-bitrate MP3.
In 2004, players using the new format did not come out: small amounts of memory and the non-proliferation of color displays interfered. But even in 2005, MTV failed to take the lead in portable video. Now the sharp loss of their positions in the market by the majority of Korean companies, the high cost of the Telechips platform prevented.
However, many Pixtree MP4 players have been released. Some models are still on sale.
Pixtree MP4 was perhaps the most successful of the proprietary formats. The power of the Telechips SOC eliminated the shortcomings of MTV and AMV. MP4 players on this format played video with resolutions up to QCIF +, and, probably, nothing prevented the creation of a QVGA player. The main disadvantages were the low frame rate – a maximum of 15 per second – and proprietary, i.e. inability to use third-party transcoders and players. In new editions of the software for the next generation of platforms, Telechips has eliminated these shortcomings by switching to support for the open Xvid format.
