Linear Acoustic takes care of transcoding at China Central Television

LA5269 at CCTV ChinaMaster Control racks at CCTV's new HD facilities in Beijing, featuring Linear Acoustic LA-5269 Dolby Digital/Plus Transcoders. Three LA-5269s are already on the air on CCTV-3, CCTV-5, and CCTV-8.
As the predominant state television broadcaster in mainland China, Chinese Central Television (CCTV) programs 24 channels accessible to more than 1 billion viewers.  Their new broadcast facilities were built to be "100% HD ready."

Since the ability to properly handle program metadata was a top priority, they specified 24 Linear Acoustic® LA-5269 Dolby® Digital/Plus Transcoders for the new plant, several of which are already up and running on CCTV-3 (Arts and Entertainment), CCTV-5 (Sports), and CCTV-8 (Series Television).

Most of CCTV's programming relies upon static metadata as set on the encoder, but from time to time, they need the ability to handle dynamic metadata as well, which the LA-5269 does with ease.  That feature played a big part in their decision to choose Linear Acoustic.

The ability to accept SDI input, which simplifies workflow, was also appealing.  Having SNMP and dual power supplies provides the stability, security, and reliability broadcasters demand in a transmission-critical

Mr. Xu Gangming, Director of CCTV's Transmission Department, summed it up this way: "The Linear Acoustic LA-5269 Dolby® Digital/Plus Transcoder plays a critical role in the MCR at CCTV's new facility.  It has not only simplified the system structure, but also provides stable, high performance 5.1-channel surround encoding for our HD channels.

It fits the rigorous requirements of handling audio metadata and supporting the top quality program production and distribution we demand at CCTV."

Daniel Wang, Linear Acoustic Senior Business Development Manager, Asia, says the company's reputation for providing excellent support was also a determining factor in choosing the LA-5269.  "We've been working side by side with the CCTV engineers since the early design phase of the project, doing our best to help make their transition to HD as smooth as possible," Wang said.
