DTS HD Encoder Suite 40: A Comparison with Other Audio Encoding and Delivery Solutions



JVC 2K - Fire TV released in UK/Ireland, provides a smart TV with Freeview Play (FVP). This device runs on the MTK T22 chipset and has Fire OS 7. JVC 2k is available with sizes 32" (HD), 40" (FHD) and 43" (FHD). Freeview Play provide access to over 70 live channels and the full suite of UK TV catch-up apps.


The EZ-KIT Lite includes an ADSP-BF548 Blackfin Processor desktop evaluation board along with an evaluation suite of the VisualDSP++ development and debugging environment, including the C/C++ compiler, assembler, and linker. The evaluation suite of VisualDSP++ is designed to be used with the EZ-KIT Lite only.

Layer 3: Known everywhere as MP3, it's the .avi of audio formats - anything can play it. Audio quality is 'average', i.e., it's the worst out of all formats, but since audio files are pretty small, people are happy to just increase the bitrate. Encoded with LAME (LAME Ain't an MP3 Encoder - yes, this is a recursive acronym. Just ignore the fact that LAME is an MP3 encoder and you'll do fine).


Different AAC encoders & decoders will implement support for different profiles above. Generally you can rely on LC support being in whatever tool you use, but HE and HEv2 are a little more hit and miss. Computer decoders should support all three, but your mileage may vary. In particular, Apple stuff only does LC.On the bright side, AAC implements 'graceful degradation', which means if a decoder tries to play back a file encoded with an unsupported profile, at least something should come out:


Implementation of the ATSC A/52 standard by Dolby Studios. Dolby Digital AC3 is Dolby's base lossy audio codec in which they have enhanced over the years to create a large umbrella suite of codecs. It is the standard audio format for DVDs and most Digital TV Broadcasts. If the file contains AC3 audio it usually means it is the original audio from the source, essentially the highest possible quality. Compared to other lossy codecs however, it is quite inefficient and space-consuming. Maximum bitrate of 640kbits and a limit of 5 channels.
