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)
The .ogg file format is a type of audio file that makes use of open source Ogg Vorbis compression. It is supported by devices such as Archos and Samsung but is not supported by Apple iOS devices. The .ogg format has been utilised for the provision of streaming audio. The file format is unlikely at present to take a dominant share of the digital music market due to the synonymous nature of MP3 with digital audio.
The .ogg format is actually a container that potentially allows for different streams of audio, video and metadata. Ogg Vorbis is the compression format. It provides medium to high quality audio at between 16 and 128 kbps/channel and is better quality sound than mp3. The OGG file type is a lossy codec which means that data is discarded as part of the compression technique, resulting in a smaller file size. Ogg files are optimised for music files, but will still be of acceptable quality for speech only files.
