The .TS file format is used to broadcast high-definition TV (HDTV) - it is specifically designed for less reliable transmission and broadcast fits well with this. When the signal gets degraded the transport stream (TS) can handle error correction and stream synchronization issues much better than other formats.
Transport stream (TS) is specified in MPEG-2, and it is a standard format for transmission and storage of audio, video, and data, and is used in broadcast systems such as DVB and ATSC. Various elements make up a transport stream - namely; Packet - A packet is the basic unit of data in a transport stream, PID - Each table or elementary stream in a transport stream is identified by a 13-bit packet ID (PID), Programs - Transport stream has a concept of programs. Each single program is described by a Program Map Table (PMT) which has a unique PID, Program Specific Information(PSI) - There are 4 PSI tables: Program Association (PAT), Program Map (PMT), Conditional Access (CAT), and Network Information (NIT), PAT - PAT stands for Program Association Table. It lists all programs available in the transport stream, PMT - Program Map Tables (PMTs) contain information about programs, PCR - To enable a decoder to present synchronized content, such as audio tracks matching the associated video, at least once each 100 ms a Program Clock Reference, or PCR is transmitted in the adaptation field of an MPEG-2 transport stream packet
Using Zamzar it is possible to convert TS files to a variety of other formats:
ts to 3gp (3GPP Multimedia File) ts to 3g2 (3GPP2 Multimedia File) ts to aac (Advanced Audio Coding File) ts to ac3 (AC3 Audio File) ts to avi (Windows video file) ts to flac (Free Lossless Audio Codec) ts to flv (Flash video) ts to gif (Compuserve graphics interchange) ts to ipad (MPEG-4 (H264) Video File) ts to iphone (MPEG-4 (H264) Video File) ts to ipod (MPEG-4 Video File) ts to mp3 (Compressed audio file) ts to mov (Apple QuickTime Movie) ts to mp4 (MPEG-4 Video File) ts to mpg (Moving Picture Experts Group File) ts to ogg (Ogg Vorbis Compressed Audio File) ts to wav (Windows audio file) ts to webm (Multimedia Container Format) ts to wmv (Windows Media Video)
MPG is commonly associated with video and audio compressions MPEG-1 or MPEG-2. This is designed to compress audio and video to formats that can be downloaded. Movies with this extension are of lower sizes and greater quality, but quality differs from original VCR videos. This file format can run on Mac, Windows and other portable devices.
MPEG-1 is a standard for lossy compression of video and audio. It is designed to compress VHS-quality RAW digital video and CD audio down to 1.5 Mbit/s (26:1 and 6:1 compression ratios respectively) without excessive quality loss, making video CDs, digital cable/satellite TV and digital audio broadcasting (DAB) possible. Today, MPEG-1 has become the most widely compatible lossy audio/video format in the world, and is used in a large number of products and technologies. Perhaps the best-known part of the MPEG-1 standard is the MP3 audio format it introduced.
