Dvb-t H 264 Codec

What technologies are being used for HD in the UK?Two technologies are being introduced to terrestrial broadcasting for Freeview HD. The first is the H.264 - aka AVC, or MPEG 4 part 10 - video codec. This can be used for both HD and SD pictures, and is much more efficient than the MPEG 2 codec used by Freeview at the moment. H.264 is already used for satellite HD services, and for terrestrial HD in other countries.

The H.264 codec requires new hardware too, in most cases other than general purpose PCs. Set-top boxes rely on custom decoding hardware to do the hard work at a reasonable price, and most current ones just understand MPEG 2 at standard definition.

Both Standard and Professional versions of ProgDVB include MPEG-2 shareware codec by Elecard. You have to register it after 21 days (Start->ProgDVB->Elecard Registrator) or use some alternative codecs. For AVC and H.264 support you should register Elecard AVC H.264 plugin for ProgDVB. The registration is done with the Serial Number provided in your purchase confirmation email..

I checked the Google Playstore and some relevant information is missing.While it says that DVB-T and DVB-T2 works, it does not specify if also H.265 (adopted by Germany) or if only DVB-T2 using the H.264 codec is supported.

The receiver offers excellent picture quality in Full HD 1080p resolution and will also display older DVB-T broadcasts with the H.264 codec. Thanks to the support of the electronic program guide (EPG), you can easily get an overview of the current broadcast of individual programs, for which you can also set up PVR recording on a USB storage device. If you do not want to watch the broadcast, the receiver can play multimedia content in the form of videos, music and pictures from a USB device.

Graceful degradation, which can be provided by employing a UEP transmission scheme, is a desired solution in broadcast transmission systems. This was recognised by DVB [3], an international consortium which develops standards for broadcast transmission. The system support for a UEP transmission scheme is one of the commercial requirements for the second generation of the DVB standard for handheld devices [4]. Moreover, DVB adopted H.264/SVC as one of the video codecs used for broadcast services [5]. However, none of the existing DVB standards natively supports UEP transmission of scalable media.

Our RF performance is such that higher orders of modulation can be used reliably. Operating in 16QAM FEC2/3 GI1/8, we achieve 8.4Mbps. The video quality our of HEVC encoding is such that it matches or exceeds the quality of H.264 codecs operating in standard DVB-T 8MHz bandwidths.

The -vcodec copy -acodec copy part instructs ffmpeg to use the same video and audio codec as in the original file (input.avi), no transcoding will be done. It is important to note that DVB standards such as DVB-T, 8VSB, and DVB-S only support MPEG-2 as the encoding standard (H.264/MPEG-4 is not officially supported).

Hi. For a while I've been using VLC to play DVB-T. It works like a charm, but I would like to use mplayer instead as it's faster and able to use vaapi properly.So what I've done is:-scanning the channels for mplayer in ~/.mplayer/channels.conf with scan utility, all fine-launching it with mplayer dvb://"TV3" for exampleThe channels by the way also appear fine in umplayer's TV list, but the codec should be MPEG4 AVC (h264), I assume that mplayer thinks it's MPEG2.Here is what I get when starting mplayer with the command above:

Thanks in advance! Currently i'm trying x264-git and ffmpeg-git from aur to see if this helps...Any help would be highly appreciated, I know h264 with dvb-t in mplayer should be possible (and maybe even vaapi). I hate VLC's resource usage.. Perhaps somehow forcing the necessary codec to h264 would fix it?

H.264 has the power to lower video bitrates by a much larger margin without compromising the quality of the video nearly as much as previous codecs. This high-efficiency video encoding is precisely what made H.264 become the most widely used codec of all time.

More advanced technology also means that H.265 requires much more advanced hardware, which has been somewhat of an obstacle in this codec gaining popularity. On the other hand, H.265 requires much less bandwidth and processing power to go through the encoding and decoding processes.

H.265 can compress videos with no visible loss of video quality. However, even if there is no perceived quality deterioration, H.265 is considered a lossy codec, so some quality loss is expected.

H.265's high efficiency codec allows users to broadcast in the lauded 4K resolution, the current gold standard for the industry. A sharper image will help your video content stand out from the competition and convey a polished, tech-savvy image of your business to your audience.

The DD4HD-R is a rack mount professional quad HDMI® encoder modulator. DD4HD-R encodes either MPEG2 or H.264 video codecs and modulates to DVB-T with simultaneous multicast IP output. In addition, DD4HD-R features two RF outputs to allow a higher bit rate per service for better picture quality and stability, especially in MPEG2 format.View More Headend Equipment

Video compression (video codecs) are mathematical algorithms that reduce the amount of information needed to depict the image. If data is not compressed it would require a storage space and a transmission bandwidth of so high capacities that its economic cost (and technical viability) would be prohibitive..

We often confuse MPEG-4 and H.264 codecs. They are not the same. MPEG-4 is a video codec featuring a number of variants, being one of them the H.264 which technically is MPEG-4 part 10.

H.264 and H.265 codecs are optimized but not limited to the High Definition and Ultra HD broadcasting respectively. This means it is possible to compress standard definition content in H.265. Therefore an H.265 broadcasting is not necessarily of Ultra HD.

Chip companies and software technology vendors such as Amphion Semiconductor, Envivio, Equator Technologies, iVAST, Texas Instruments, UB Video and VideoLocus will unveil their strategies for the emerging video codec. 2b1af7f3a8
