HDMI CEC IP

Overview

Key Features

• Supports HDMI-CEC version 1.4b and 2.0 specifications
• CEC 2.0 is designed to be a backward compatible extension of CEC 1.4b
• HDMI-CEC device supports full Initiator and Follower functionality.
• Supports automatic synchronization to align sampling point.
• Supports programmable Safe sample point period.
• Supports programmable data bit timing for Logic 0 and Logic 1
• Supports the full range of CEC bit timings that guarantees receiving CEC messages from any CEC device
• Supports following CEC Features,
• -> One Touch Play - Allows a device to be played and become the active source with a single button press.
• -> System Standby - Enables the user to switch all devices to the Standby state with one button press.
• -> One Touch Record - Offers a What You See Is What You Record (WYSIWYR) facility.
• -> Timer Programming - Allows the user to program the timers in a Recording Device from an EPG running on a TV or STB.
• -> Deck Control - Enables a device to control (e.g. play, fast forward etc.) and interrogate a Playback Device (a deck).
• -> Tuner Control - Allows a device to control the tuner of another device.
• -> Device Menu Control - Enables a device to control the menu of another device by passing through user interface commands.
• -> Remote Control Pass Through - Enables remote control commands to be passed through to other devices within the system.
• -> System Audio Control - Allows an Audio Amplifier / Receiver to be used with the TV.
• -> Device OSD Name Transfer - Enables devices to upload their preferred OSD name to the TV.
• -> Device Power Status - Allows the current power status of a device to be discovered.
• -> OSD Display - Enables a device to use the on-screen display of the TV to display text strings.
• -> Routing Control - Allows the control of CEC Switches for streaming of a new source device.
• -> System Information - Queries the system to determine device addresses and language.
• -> Vendor Specific Commands - Allows a set of vendor-defined commands to be used between devices of that vendor.
• -> Audio Rate Control - Allows an Amplifier to fractionally increase or decrease the playback rate of an audio source.
• -> General Protocol - Defines the protocol general rules
• Supports to configure with multi-logical address, making it suitable for devices that have multiple functions
• Supports to generate interrupts whenever Follower detects new header targetted to itself
• Supports to handle Signal Free Time rules, transmission collision, arbitration and initiator error notification
• Fully synthesizable
• Static synchronous design
• No internal tri-states
• Scan test ready
• Simple interface allows easy connection to microprocessor/microcontroller devices

Benefits

• Single site license option is provided to companies designing in a single site.
• Multi sites license option is provided to companies designing in multiple sites.
• Single Design license allows implementation of the IP Core in a single FPGA bitstream and ASIC.
• Unlimited Designs, license allows implementation of the IP Core in unlimited number of FPGA bitstreams and ASIC designs.
