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
GSRT is a purpose-built ringtone format developed by Grandstream Networks for its line of IP phones and VoIP endpoint devices. Each file begins with a fixed-size header identifying sample rate (typically 8 kHz or 16 kHz), bit depth, and payload length, followed by PCM or mu-law encoded audio data optimized for the small speakers found in desk phones. The design prioritizes minimal decode complexity — Grandstream handsets run on embedded processors with limited memory, so the format avoids transform stages or complex bitstream parsing. Ringtones are usually provisioned through a web management interface or a centralized configuration server, letting IT administrators push branded audio to an entire fleet of phones at once. Although GSRT occupies a narrow niche within enterprise VoIP telephony, its straightforward binary layout means conversion tools can map the payload directly to WAV with minimal effort. Key advantages include rock-solid playback reliability on Grandstream hardware, negligible latency from file read to speaker output, and seamless integration with the provisioning ecosystem for company-wide ringtone deployment.
