About formats

TS (MPEG Transport Stream) is a standard container format specified as part of the MPEG-2 systems layer (ISO/IEC 13818-1), standardized by the Moving Picture Experts Group in 1995. Transport streams are designed for communication and storage environments where data loss or corruption is possible, such as broadcast television, satellite transmission, and network streaming. The format divides content into fixed-size 188-byte packets, each carrying a 4-byte header with synchronization, error indication, and stream identification information. This packet structure enables receivers to rapidly resynchronize after signal interruptions, a critical capability for real-time broadcast delivery that distinguishes transport streams from program streams designed for reliable storage media. TS can multiplex multiple programs into a single stream, with Program Specific Information (PSI) tables describing the structure and content of each program. The format supports virtually any audio and video codec, though it most commonly carries MPEG-2 video, H.264, or HEVC alongside AAC, AC-3, or MPEG audio. TS is the backbone of digital television delivery worldwide, used by DVB, ATSC, and ISDB broadcasting standards as well as IPTV and OTT streaming services utilizing HTTP Live Streaming (HLS). Resilience, standardized structure, and broad codec support make TS equally at home in live broadcast chains and file-based recording workflows.
Initial release: 1995
GSM 06.10 (Full Rate) is the foundational speech codec of the Global System for Mobile Communications standard, ratified by ETSI in 1991 and deployed across hundreds of cellular networks worldwide. Operating at a fixed 13 kbit/s, the algorithm applies Regular Pulse Excitation with Long-Term Prediction (RPE-LTP) to compress 20 ms frames of 8 kHz mono speech into just 33 bytes each. This approach models the vocal tract as a linear predictive filter, encodes the excitation signal, and leverages pitch periodicity for further reduction — tuned to deliver intelligible voice under the bandwidth constraints of early digital mobile channels. The codec powers not only GSM telephony but also many VoIP applications, voicemail systems, and IVR platforms that benefit from its low bitrate. Three concrete advantages stand out. First, extraordinary compression: one minute of speech fits in roughly 100 KB, enabling efficient storage and transmission. Second, universal tooling — libraries such as libgsm and SoX handle encoding and decoding on every major platform. Third, a royalty-free patent landscape that has encouraged adoption across open-source telephony projects like Asterisk and FreeSWITCH.

Frequently Asked Questions

Why convert TS to GSM?

GSM provides GSM 06.10 speech codec for cellular telephony. Converting extracts compatible audio data from your TS broadcast recordings.

What software handles GSM?

Specialized audio tools, SoX, and format-specific applications handle GSM files for playback and processing.

Is GSM widely supported?

GSM serves specific use cases. For general audio, MP3, WAV, or FLAC are more broadly compatible.

Can I adjust settings?

Yes — configure sample rate and encoding parameters before converting to match your target system.

Is batch conversion available?

Upload multiple TS files and extract GSM audio from each simultaneously in one session.
