A dual codec DVR offers the best solution for those needing to efficiently manage the viewing and recording of multiple cameras both locally and remotely without compromising video quality over data throughput and vice versa.The ARM Electronics JH8D3000 uses JPEG 2000 for recording and H.264 for network transmission. This way you are assured of getting maximum image quality when it's needed most and at the same time reduce the load on the network.ARM Electronics also equipped the JH8D3000 with a jog shuttle so you'll get to control playback speeds and frame by frame advancement in the same convenient and accurate manner you are accustomed to in an industrial grade VTR.Also of great importance is the DVR's built-in DVD burner, which by recording footage to readily available optical media provides you with a fast and easy way for transferring and archiving event material.

• H.264 Codec

H.263 General InformationH.263 is a standard video-conferencing codec. Video Codec Reference Source CodeI have had so many requests for reference code, Well here is a link, you on you own after that.These are NOT OPEN SOURCE or FREE. There are all sorts of Liscences and Patents, so I recomend you do you homework before making a product from this. All of these links were found through Google once you know what your looking for.They are on other peoples server, I am not in any way responsibe for this code being available publicly nor for it's integrity or even explaining how it works.That being said, it's a great source to learn how these codec's work, the code all in C (Not C) and run well on Unix/Linux. The code is NOT Optimized in any way, shape or form, so it's slow! If any of these links are broken, shoot me an E-mail, I recomend google searching the file names, your bound to find someone with this code lying around.H.263 Source Code.Draft, ITU H.263 Standards DocumentITU H.263, H.263L, H.26L, H.263E, ISO/IEC 14496 These video codecs are the Basis for MPEG4 Simple Profile. MPEG-4 adds advanced error detection and correction services on top of H.263.3GPP and ISMA are versions of H.263 and MPEG-4 for streaming and mobile applications.

These are really a variation of Transport stream.There is now MPEG-4 AVC/H.264Also called JVT ITU H.264 ITU-T Rec. H.264 MPEG-4 Part 10 ISO 14496-10 AVC Advanced Video Coding AVC.whatever you call it, this is revolutionary.

H.264 is being widely recognized as the future platform of video compression for applications such as new HDTV services, portable game console, mobile broadcast video services, video on solid-state camcorders, instant video messaging on cell phone. H.264 is the most advanced video coding standard available today. It uses many new coding techniques not available in MPEG2, MPEG4 and H.263. This chart shows the evolution of video coding standards. This revolutionary technology promises to facilitate whole new applications, and to unleash dramatic cost savings in the broad spectrum of video applications. Examples include:.

Transmission of HDTV programs twice as efficiently than with MPEG2. Storing 2 Hrs of HD Movies on an ordinary red laser DVD.

H.264 Codec

Facilitating the emergence of HD content PVR for consumer use. Mintek rc 600b manually. Doubling the stored program time of PVRs by transcoding the recorded content to H264. Affordable high picture quality solid state/HDD based camcorder.

CIF quality Video programming for mobile devices. For you who are already familiar with video compression standards and want to know more about the H.264 standard, the following publication (19 pages) is an excellent source:A draft of the whole H.264 Standard (264 pages) from the 'ITU-T 7th meeting: Pattaya, Thailand, 7-14 March 2003', is also downloadable below:H.264 PerformanceThe new H.264 video compression standard is the first to be ratified by both the ISO/IEC. It raises the bar considerably compared to MPEG4-ASP and yields better picture quality while significantly lowering the bit rate. This allows lower overall system cost, reduced infrastructure requirements and enables many new video applications. H.264 is considered the greatest achievement in video compression in the past 10 years and is already finding its way into many mainstream video applications.Below follow some practical comparisons between different coding technologies for 90 min of DVD quality video:H.264 Patent Licensing FeesOne more great aspect of H.264 is the licensing fee structure by the patent holders of technology that went into the standard. MPEG4 was significantly hampered by complicated and excessive licensing fees demanded by its patent holder. For H.264 the industry has learned from its mistakes with MPEG-4 and created a very simple and low cost licensing structure.

There are two H.264 patent licensing organizations: MPEG-LA and Via Licensing. Both have similar licensing terms.
