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.

CVU is an unsigned variant of the CVS telephony audio format, differing in how delta-encoded values are represented in the binary stream. While CVS stores slope delta values as signed quantities, CVU treats them as unsigned, shifting the numerical interpretation of each sample. Both share the underlying CVSD modulation technique — 1-bit adaptive delta coding where step size varies according to recent output bit patterns — operating at comparable rates, typically 16 kbps for narrowband voice at 8 kHz. The signed-versus-unsigned distinction matters at the decoder, where correct interpretation determines proper waveform reconstruction. CVU files appear in telephony and embedded communication contexts where hardware adopted the unsigned convention. A practical advantage is straightforward interfacing with systems using unsigned arithmetic natively, avoiding sign extension in decoders. Like its signed counterpart, CVU achieves extreme bandwidth efficiency, compressing voice into compact bitstreams for constrained links. SoX supports CVU, providing a reliable path for converting these niche telephony recordings into modern formats for analysis or archival.

Frequently Asked Questions

Why convert TS to CVU?

CVU provides CVU variant encoding for telephony platforms. Converting extracts compatible audio data from your TS broadcast recordings.

What software handles CVU?

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

Is CVU widely supported?

CVU 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 CVU audio from each simultaneously in one session.
